  • Psychological/behavioral interventions for emerging adults with chronic pain. Frontiers in pain research (Lausanne, Switzerland) Foy, J. G., Kechichian, S., Foy, M. R., Ziadni, M. 2024; 5: 1253700

    Abstract

    Emerging adults, of whom significant numbers report chronic pain, are characterized as having unique needs and challenges. Psychological/behavioral treatments found to be beneficial for reducing pain outcomes in children and adults are understudied in emerging adults. Following a systematic review of the literature, our objective is to report on quantitative studies of psychological/behavioral interventions for chronic pain in emerging adults.We conducted a search of six databases (Cochrane Central Register of Controlled Trials, Google Scholar, ProQuest, PsycINFO, PubMed, and Web of Science) and reference sections in dissertations and systematic reviews to 4/29/2023. Keywords and phrases were search term combinations of "chronic/persistent pain", "emerging/young adults," and "intervention/treatment" using Boolean logic.Our review resulted in identifying 37 articles, of which 2 duplicates were removed, and 31 were further excluded by a screening process based on various inclusionary and exclusionary criteria. The search yielded four studies on psychological/behavioral interventions (yoga, acceptance and commitment therapy and relaxation), all of which positively affected the pain experience and/or pain-related outcomes. These studies presented issues in design such as not being blinded or randomized, having a small sample size, and potential confounds that were not reported or examined.The low number of studies reveals a large gap in the literature and is a call-to-action to further expand our understanding of effective and safer psychological/behavioral therapies for chronic pain in emerging adults. Successful pain management during this developmental phase may help young adults achieve positive trajectories for personal, occupational, relational, and health aspects of their lives.

  • Is there an association between lateralization of chronic pain in the body and depression? The journal of pain Edwards, K. A., Lii, T., Schouten, T. D., Kearney, K. M., Ziadni, M. S., Darnall, B. D., Mackey, S. C., Gilam, G. 2024

    Abstract

    Depression commonly co-occurs with chronic pain and can worsen pain outcomes. Recent theoretical work has hypothesized that pain localized to the left hemibody is a risk factor for worse depression due to overlap in underlying neural substrates. This hypothesis has not been tested a priori. Using a large sample of treatment-seeking adults with mixed-etiology chronic pain (N=1,185), our cross-sectional study tested whether patients with left-sided pain endorse worse depressive symptoms. We also examined differences in other pain-related functioning measures. We tested four comparisons based on painful body areas using the CHOIR bodymap: 1) only left-sided (OL) vs. any right-sided pain; 2) only right-sided (OR) vs. any left-sided pain; 3) OL vs. OR vs. bilateral pain; and 4) more left-sided vs. more right-sided vs. equal-sided pain. ANOVA models showed OL pain was not associated with worse depression (F=5.50, p=.019). Any left-sided pain was associated with worse depression, though the effect was small (F=8.58, p=.003, Cohens d=.29). Bilateral pain was associated with worse depression (F=8.05, p<.001, Cohens d=.24-.33). Regardless of pain location, more body areas endorsed was associated with greater depression. Although a more rigorous assessment of pain laterality is needed, our findings do not support the hypothesis that left lateralized pain is associated with worse depression. PERSPECTIVE: Pain lateralized to the left side of the body has been hypothesized as a risk factor for worse depression in chronic pain, despite never being tested in a large, real-world sample of patients with chronic pain. Findings showed that more widespread pain, not pain laterality, was associated with worse depression.

  • Empowered Relief, cognitive behavioral therapy, and health education for people with chronic pain: a comparison of outcomes at 6-month Follow-up for a randomized controlled trial. Pain reports Darnall, B. D., Burns, J. W., Hong, J., Roy, A., Slater, K., Poupore-King, H., Ziadni, M. S., You, D. S., Jung, C., Cook, K. F., Lorig, K., Tian, L., Mackey, S. C. 2024; 9 (1): e1116

    Abstract

    We previously conducted a 3-arm randomized trial (263 adults with chronic low back pain) which compared group-based (1) single-session pain relief skills intervention (Empowered Relief; ER); (2) 8-session cognitive behavioral therapy (CBT) for chronic back pain; and (3) single-session health and back pain education class (HE). Results suggested non-inferiority of ER vs. CBT at 3 months post-treatment on an array of outcomes.Here, we tested the durability of treatment effects at 6 months post-treatment. We examined group differences in primary and secondary outcomes at 6 months and the degree to which outcomes eroded or improved from 3-month to 6-month within each treatment group.Empowered Relief remained non-inferior to CBT on most outcomes, whereas both ER and CBT remained superior to HE on most outcomes. Outcome improvements within ER did not decrease significantly from 3-month to 6-month, and indeed ER showed additional 3- to 6-month improvements on pain catastrophizing, pain bothersomeness, and anxiety. Effects of ER at 6 months post-treatment (moderate term outcomes) kept pace with effects reported by participants who underwent 8-session CBT.The maintenance of these absolute levels implies strong stability of ER effects. Results extend to 6 months post-treatment previous findings documenting that ER and CBT exhibit similarly potent effects on outcomes.

  • Establishing the interpretability and utility of the 4-item BriefPCS. Scientific reports You, D. S., Cook, K. F., Lannon, E. W., Ziadni, M. S., Darnall, B. D., Mackey, S. C. 2023; 13 (1): 21272

    Abstract

    To reduce the patient burden associated with completing the 13-item Pain Catastrophizing Scale (PCS), the 4-item "BriefPCS" was developed. To date, no crosswalk has been developed that associates scores on the BriefPCS with PCS scores. Further, no study has compared the use of BriefPCS and PCS scores in a randomized clinical trial (RCT). We aimed to: (1) establish the interpretability of BriefPCS scores in reference to PCS scores, (2) compare the concurrent validity between the BriefPCS and PCS, and (3) asssess the use of BriefPCS in an RCT. First, we conducted equipercentile linking, created a crosswalk that associated scores of BriefPCS with PCS, and calculated differences between PCS and crosswalked PCS scores. Secondly, we compared Bootstrap correlation coefficients between PCS and self-reported measures of other domains. Lastly, we compared results from an RCT using BriefPCS scores versus PCS scores. Findings indicated that the correlation coefficient estimates with the BriefPCS and PCS scores were not significantly different. BriefPCS and PCS scores had similar ability to detect treatment-related changes. The BriefPCS scores validly, reliably, and accurately distinguish levels of pain catastrophizing. Additionally, the BriefPCS scores are sensitive to changes after behavioral interventions, with less respondent burden compared to the PCS scores.

  • A Longitudinal Investigation of the Impact of COVID-19 on Patients with Chronic Pain. The journal of pain Ziadni, M. S., Jaros, S., Anderson, S. R., You, D. S., Darnall, B. D., Mackey, S. C. 2023

    Abstract

    The COVID-19 pandemic prompted unexpected changes in the healthcare system. This current longitudinal study had two aims: 1) describe the trajectory of pandemic-associated stressors and patient-reported health outcomes among patients receiving treatment at a tertiary pain clinic over two years (May 2020 to June 2022); and 2) identify vulnerable subgroups. We assessed changes in pandemic-associated stressors and patient-reported health outcome measures. The study sample included 1,270 adult patients who were predominantly female (74.6%), White (66.2%), non-Hispanic (80.6%), married (66.1%), not on disability (71.2%), college-educated (59.45%), and not currently working (57.9%). We conducted linear mixed effect modeling to examine the main effect of time with controlling for a random intercept. Findings revealed a significant main effect of time for all pandemic-associated stressors except financial impact. Over time, patients reported increased proximity to COVID-19, but decreased pandemic-associated stressors. A significant improvement was also observed in pain intensity, pain catastrophizing, and PROMIS-pain interference, sleep, anxiety, anger, and depression scores. Demographic-based subgroup analyses for pandemic-associated stressors revealed that younger adults, Hispanics, Asians, and patients receiving disability compensation were vulnerable groups either during the initial visit or follow-up visits. We observed additional differential pandemic effects between groups based on participant sex, education level, and working status. In conclusion, despite unanticipated changes in pain care services during the pandemic, patients receiving pain treatments adjusted to pandemic-related stressors and improved their health status over time. As the current study observed differential pandemic impacts on patient subgroups, future studies should investigate and address the unmet needs of vulnerable subgroups. PERSPECTIVE: Over a two-year timeframe, the pandemic did not adversely influence physical and mental health among treatment-seeking patients with chronic pain. Patients reported small but significant improvements across indices of physical and psychosocial health. Differential impacts emerged among groups based on ethnicity, age, disability status, gender, education level, and working status.

  • Spontaneous self-affirmation: an adaptive coping strategy for people with chronic pain. Scandinavian journal of pain You, D. S., Hettie, G., Darnall, B. D., Ziadni, M. S. 2023

    Abstract

    OBJECTIVES: Self-affirmation may be a promising treatment strategy for improving clinical outcomes. This study examined the association between self-affirmation and self-reported health status among people with chronic pain.METHODS: In this cross-sectional study, 768 treatment seeking people (female 67.2%, mean age=50.4years with SD of 17.1, White/Caucasian 59.9%) completed surveys using a learning healthcare system. Measures included spontaneous self-affirmation (SSA) items, PROMIS outcome measures, and Pain Catastrophizing Scale (PCS). Multiple regressions were conducted to examine if strength-based SSA, value-based SSA, and their interaction would predict perceived health status and pain coping strategy. Sensitivity analysis was done by performing additional regressions with covariates (age, sex, race/ethnicity, and education). Lastly, exploratory analysis examined if average SSA scores would have a linear relationship with perceived health status.RESULTS: The strength x value-based SSA interaction significantly predicted the PROMIS-depression, anxiety, and social isolation T-scores (ps≤0.007), but not anger T-scores (p=0.067). Specifically, greater tendency to use both SSA styles predicted less symptoms of depression, anxiety and social isolation. This interaction remained significant when controlling for the covariates. The two SSA styles and their interaction did not significantly predict pain interference, sleep disturbance, fatigue, average pain rating and PCS scores (ps≥0.054). Exploratory analysis revealed SSA average scores did not have a significant linear relationship with perceived health status.CONCLUSIONS: The current study showed self-affirmation as being associated with better psychosocial health, but not associated with physical health and pain catastrophizing among patients with chronic pain. Our findings suggested the potential benefit of incorporating strength- and value-based affirmations in pain intervention approaches.

  • Association between history of childbirth and chronic, functionally significant back pain in later life. BMC women's health Zhang, M., Cooley, C., Ziadni, M. S., Mackey, I., Flood, P. 2023; 23 (1): 4

    Abstract

    BACKGROUND: Back pain is more prevalent among women than men. The association with sex could be related to pregnancy and childbirth, unique female conditions. This association has not been thoroughly evaluated.METHODS: Using a retrospective cohort design, we evaluated the relationship between history of childbirth on the prevalence and severity of functionally consequential back pain in 1069 women from a tertiary care pain management clinic. Interactions among preexisting, acute peripartum, and subsequent back pain were evaluated as secondary outcomes among the parous women using logistic and linear regression as appropriate.RESULTS: The women who had given birth had a higher risk for functionally significant back pain compared to women who had not given birth (85% vs 77%, p<0.001, Risk Ratio 1.11 [1.04-1.17]). The association was preserved after correction for age, weight, and race. Back pain was also more slightly severe (Numerical Rating Score for Pain 7[5-8] vs 6[5-7] out of 10, p=0.002). Women who recalled severe, acute postpartum back pain had a higher prevalence of current debilitating back pain (89% vs 75%, Risk Ratio 1.19 (1.08-1.31), p=0.001). Twenty-eight percent of acute postpartum back pain never resolved and 40% reported incomplete resolution.CONCLUSIONS: A history of pregnancy and childbirth is a risk factor for chronic functionally significant back pain in women. Severe acute postpartum back pain is a risk factor for future disability suggesting that the peripartum period may provide an important opportunity for intervention. Early recognition and management may mitigate future disability.TRIAL REGISTRATION: The study was registered with clinicaltrials.gov as "Association Between Chronic Headache and Back Pain with Childbirth" (NCT04091321) on 16/09/2019 before it was initiated.

  • Innovative treatment formats, technologies, and clinician trainings that improve access to behavioral pain treatment for youth and adults. Frontiers in pain research (Lausanne, Switzerland) Darnall, B. D., Edwards, K. A., Courtney, R. E., Ziadni, M. S., Simons, L. E., Harrison, L. E. 2023; 4: 1223172

    Abstract

    Chronic pain is prevalent across the life span and associated with significant individual and societal costs. Behavioral interventions are recommended as the gold-standard, evidence-based interventions for chronic pain, but barriers, such as lack of pain-trained clinicians, poor insurance coverage, and high treatment burden, limit patients' ability to access evidenced-based pain education and treatment resources. Recent advances in technology offer new opportunities to leverage innovative digital formats to overcome these barriers and dramatically increase access to high-quality, evidenced-based pain treatments for youth and adults. This scoping review highlights new advances. First, we describe system-level barriers to the broad dissemination of behavioral pain treatment. Next, we review several promising new pediatric and adult pain education and treatment technology innovations to improve access and scalability of evidence-based behavioral pain treatments. Current challenges and future research and clinical recommendations are offered.

  • "Pain, Stress, and Emotions": Uncontrolled trial of a single-session, telehealth, emotional awareness and expression therapy class for patients with chronic pain. Frontiers in pain research (Lausanne, Switzerland) Ziadni, M. S., Sturgeon, J. A., Lumley, M. A. 2022; 3: 1028561

    Abstract

    Trauma- and emotion-focused chronic pain interventions, particularly Emotional Awareness and Expression Therapy (EAET), show much promise for reducing pain and improving functioning. We developed a novel, single-session, telehealth-delivered EAET class ("Pain, Stress, and Emotions"; PSE) and tested it on adults with chronic pain of mixed etiology.After an initial developmental phase, we conducted an uncontrolled trial, providing PSE to 74 individuals with chronic pain (63.5% female; 64.9% White; 60.8% with pain duration >5 years) in four class administrations. Participants completed self-report measures (primary outcomes: pain intensity and pain interference) at baseline and multiple follow-ups to 12 weeks. Linear mixed-models examined changes over time, and effect sizes were calculated on change from baseline to 4-week (primary endpoint) and 12-week follow-ups. The trial was registered with clinicaltrials.gov (NCT05014126).Participants reported high satisfaction with the PSE class. Pain intensity showed a significant, medium reduction across time (p < .001; d = 0.60 at 4 weeks); one-quarter of participants had clinically meaningful pain reduction (≥30%). Pain interference had a large reduction (p < .001; d = 0.74). There were significant but smaller improvements in most secondary outcomes (ds = 0.15 to 0.55; ps < .01). Effects were generally maintained or increased at 12-week follow-up. Higher education and baseline ambivalence over emotional expression predicted greater pain reductions.People taking this EAET class had reduced pain severity and interference and improvements in other pain-related outcomes. The single-session, telehealth class holds promise as an easily delivered, efficient, and potentially impactful intervention for some patients with chronic pain, although controlled trials are needed.

  • Patient Responses to the Term Pain Catastrophizing: Thematic Analysis of Cross-sectional International Data. The journal of pain Webster, F., Connoy, L., Longo, R., Ahuja, D., Amtmann, D., Anderson, A., Ashton-James, C. E., Boyd, H., Chambers, C. T., Cook, K. F., Cowan, P., Crombez, G., Feinstein, A. B., Fuqua, A., Gilam, G., Jordan, I., Mackey, S. C., Martins, E., Martire, L. M., O'Sullivan, P., Richards, D. P., Turner, J. A., Veasley, C., Würtzen, H., Yang, S. Y., You, D. S., Ziadni, M., Darnall, B. D. 2022

    Abstract

    Pain catastrophizing is understood as a negative cognitive and emotional response to pain. Researchers, advocates and patients have reported stigmatizing effects of the term in clinical settings and the media. We conducted an international study to investigate patient perspectives on the term pain catastrophizing. Open-ended electronic patient and caregiver proxy surveys were promoted internationally by collaborator stakeholders and through social media. 3,521 surveys were received from 47 countries (77.3% from the U.S.). The sample was mainly female (82.1%), with a mean age of 41.62 (SD 12.03) years; 95% reported ongoing pain and pain duration > 10 years (68.4%). Forty-five percent (n = 1,295) had heard of the term pain catastrophizing; 12% (n= 349) reported being described as a 'pain catastrophizer' by a clinician with associated high levels of feeling blamed, judged, and dismissed. We present qualitative thematic data analytics for responses to open-ended questions, with 32% of responses highlighting the problematic nature of the term. We present the patients' perspective on the term pain catastrophizing, its material effect on clinical experiences, and associations with negative gender stereotypes. Use of patient-centered terminology may be important for favorably shaping the social context of patients' experience of pain and pain care. PERSPECTIVE: : Our large international patient survey results show that 45% of the sample had heard of the term pain catastrophizing, about one-third spontaneously rated the term as problematic, and 12% reported having the term applied to them with most reporting this to be a negative experience. Clinician education regarding the use of patient-centered terminology may help to improve patients' experience of care and reduce stigma.

  • Intensity of Chronic Low Back Pain and Activity Interference: A Daily Diary Study of the Moderating Role of Cognitive Pain Coping Strategies. Pain medicine (Malden, Mass.) Vertsberger, D., Talmon, A., Ziadni, M., Kong, J., Darnall, B. D., Manber, R., Mackey, S., Gross, J. J. 2022

    Abstract

    OBJECTIVE: Chronic low back pain (CLBP) has a significant negative impact on daily functioning, particularly for those with challenges coping adaptively with ongoing pain. However, the dynamics of pain coping in daily life remain understudied. Therefore, we examined the extent to which pain intensity interferes with daily activities, and assessed whether pain coping strategies (as assessed using daily diaries) moderated this link.METHOD: We analyzed diary data from a sample of 84 participants with CLBP who completed daily diaries for up to 30days rating pain intensity, pain interference with daily activities, and their use of pain coping strategies, including pain rumination (i.e., repetitive thinking about the pain and its causes), reappraisal (i.e., evaluating one's pain less negatively or more positively), and distraction (i.e., diverting attention from the pain). We hypothesized that these coping strategies would moderate the associations between pain and pain interference with daily activities, although in different directions.RESULTS: Results suggest that pain rumination strengthens the association between pain intensity and pain interference both on the person and day level, while pain reappraisal and distraction weaken this association, at the day and person levels, respectively.CONCLUSION: Our findings suggest that those who are more preoccupied with their pain and those who are less likely to reappraise their pain have more pain interference with daily activities. These findings build on prior work on pain coping by using daily diaries and highlight two pain coping strategies that have particular relevance for reducing the impact of CLBP in daily life.

  • CHOIRBM: An R package for exploratory data analysis and interactive visualization of pain patient body map data. PLoS computational biology Cramer, E., Ziadni, M., Scherrer, K. H., Mackey, S., Kao, M. 2022; 18 (10): e1010496

    Abstract

    Body maps are commonly used to capture the location of a patient's pain and thus reflect the extent of pain throughout the body. With increasing electronic capture body map information, there is an emerging need for clinic- and research-ready tools capable of visualizing this data on individual and mass scales. Here we propose CHOIRBM, an extensible and modular R package and companion web application built on the grammar of graphics system. CHOIRBM provides functions that simplify the process of analyzing and plotting patient body map data integrated from the CHOIR Body Map (CBM) at both individual patient and large-dataset levels. CHOIRBM is built on the popular R graphics package, ggplot2, which facilitates further development and addition of functionality by the open-source development community as future requirements arise. The CHOIRBM package is distributed under the terms of the MIT license and is available on CRAN. The development version of the package with the latest functions may be installed from GitHub. Example analysis using CHOIRBM demonstrates the functionality of the modular R package and highlights both the clinical and research utility of efficiently producing CBM visualizations.

  • "My Surgical Success": Feasibility and Impact of a Single-Session Digital Behavioral Pain Medicine Intervention on Pain Intensity, Pain Catastrophizing, and Time to Opioid Cessation After Orthopedic Trauma Surgery-A Randomized Trial. Anesthesia and analgesia Ziadni, M. S., You, D. S., Keane, R., Salazar, B., Jaros, S., Ram, J., Roy, A., Tanner, N., Salmasi, V., Gardner, M., Darnall, B. D. 2022

    Abstract

    Behavioral pain treatments may improve postsurgical analgesia and recovery; however, effective and scalable options are not widely available. This study tested a digital perioperative behavioral medicine intervention in orthopedic trauma surgery patients for feasibility and efficacy for reducing pain intensity, pain catastrophizing, and opioid cessation up to 3 months after surgery.A randomized controlled clinical trial was conducted at an orthopedic trauma surgery unit at a major academic hospital to compare a digital behavioral pain management intervention ("My Surgical Success" [MSS]) to a digital general health education (HE) intervention (HE; no pain management skills). The enrolled sample included 133 patients; 84 patients were randomized (MSS, N = 37; HE, N = 47) and completed study procedures. Most patients received their assigned intervention within 3 days of surgery (85%). The sample was predominantly male (61.5%), White (61.9%), and partnered (65.5%), with at least a bachelor's degree (69.0%). Outcomes were collected at 1-3 months after intervention through self-report e-surveys and electronic medical record review; an intention-to-treat analytic framework was applied. Feasibility was dually determined by the proportion of patients engaging in their assigned treatment and an application of an 80% threshold for patient-reported acceptability. We hypothesized that MSS would result in greater reductions in pain intensity and pain catastrophizing after surgery and earlier opioid cessation compared to the digital HE control group.The engagement rate with assigned interventions was 63% and exceeded commonly reported rates for fully automated Internet-based e-health interventions. Feasibility was demonstrated for the MSS engagers, with >80% reporting treatment acceptability. Overall, both groups improved in the postsurgical months across all study variables. A significant interaction effect was found for treatment group over time on pain intensity, such that the MSS group evidenced greater absolute reductions in pain intensity after surgery and up to 3 months later (treatment × time fixed effects; F[215] = 5.23; P = .024). No statistically significant between-group differences were observed for time to opioid cessation or for reductions in pain catastrophizing (F[215] = 0.20; P = .653), although the study sample notably had subclinical baseline pain catastrophizing scores (M = 14.10; 95% confidence interval, 11.70-16.49).Study findings revealed that a fully automated behavioral pain management skills intervention (MSS) may be useful for motivated orthopedic trauma surgery patients and reduce postsurgical pain up to 3 months. MSS was not associated with reduced time to opioid cessation compared to the HE control intervention.

  • The impact of COVID-19 on patients with chronic pain seeking care at a tertiary pain clinic. Scientific reports Ziadni, M. S., You, D. S., Cramer, E. M., Anderson, S. R., Hettie, G., Darnall, B. D., Mackey, S. C. 2022; 12 (1): 6435

    Abstract

    Empirical data on the health impacts of the COVID-19 pandemic remain scarce, especially among patients with chronic pain. We conducted a cross-sectional study matched by season to examine patient-reported health symptoms among patients with chronic pain pre- and post-COVID-19 pandemic onset. Survey responses were analyzed from 7535 patients during their initial visit at a tertiary pain clinic between April 2017-October 2020. Surveys included measures of pain and pain-related physical, emotional, and social function. The post-COVID-19 onset cohort included 1798 initial evaluations, and the control pre-COVID-19 cohort included 5737 initial evaluations. Patients were majority female, White/Caucasian, and middle-aged. The results indicated that pain ratings remained unchanged among patients after the pandemic onset. However, pain catastrophizing scores were elevated when COVID-19 cases peaked in July 2020. Pain interference, physical function, sleep impairment, and emotional support were improved in the post-COVID-19 cohort. Depression, anxiety, anger, and social isolation remained unchanged. Our findings provide evidence of encouraging resilience among patients seeking treatment for pain conditions in the face of the COVID-19 pandemic. However, our findings that pain catastrophizing increased when COVID-19 cases peaked in July 2020 suggests that future monitoring and consideration of the impacts of the pandemic on patients' pain is warranted.

  • Comparing Perceived Pain Impact Between Younger and Older Adults With High Impact Chronic Pain: A Cross-Sectional Qualitative and Quantitative Survey. Frontiers in pain research (Lausanne, Switzerland) You, D. S., Ziadni, M. S., Hettie, G., Darnall, B. D., Cook, K. F., Von Korff, M. R., Mackey, S. C. 2022; 3: 850713

    Abstract

    High impact chronic pain (HICP) is a recently proposed concept for treatment stratifying patients with chronic pain and monitoring their progress. The goal is to reduce the impact of chronic pain on the individual, their family, and society. The US National Pain Strategy defined HICP as the chronic pain associated with substantial restrictions on participation in work, social, and self-care activities for at least 6 months. To understand the meaning and characteristics of HICP from the younger (<65 years old) and older adults (≥65 years old) with chronic pain, our study examined patients' perceived pain impact between the two age groups. We also characterize the degree of pain impact, assessed with the Patient-Reported Outcomes Measurement Information System (PROMIS) pain interference (PI), between adults and older adults with HICP. We recruited patients at a tertiary pain clinic. The survey included open-ended questions about pain impact, the Graded Chronic Pain Scale-Revised to identify patients' meeting criteria for HICP, and the Patient-Reported Outcomes Measurement Information System (PROMIS) 8-item PI short form (v.8a). A total of 55 younger adults (65.5% women, 72.7% HICP, mean age = 55.0 with SD of 16.2) and 28 older adults (53.6% women, 64.3% HICP, mean age = 72.6 with SD of 5.4) with chronic pain participated in this study. In response to an open-ended question in which participants were asked to list out the areas of major impact pain, those with HICP in the younger group most commonly listed work, social activity, and basic physical activity (e.g., walking and standing); for those in the older group, basic physical activity, instrumental activity of daily living (e.g., housework, grocery shopping), and participating in social or fun activity for older adults with HICP were the most common. A 2 * 2 ANOVA was conducted using age (younger adults vs. older adults) and HICP classification (HICP vs. No HICP). A statistically significant difference was found in the PROMIS-PI T-scores by HICP status (HICP: M = 58.4, SD = 6.3; No HICP: M = 67.8, SD = 6.3), but not by age groups with HICP. In conclusion, perceived pain impacts were qualitatively, but not quantitatively different between younger and older adults with HICP. We discuss limitations and offer recommendations for future research.

  • Lack of Premeditation Predicts Aberrant Behaviors Related to Prescription Opioids in Patients with Chronic Pain: A Cross-Sectional Study. Substance use & misuse Hettie, G., Nwaneshiudu, C., Ziadni, M. S., Darnall, B. D., Mackey, S. C., You, D. S. 2021: 1-6

    Abstract

    OBJECTIVE: In light of the opioid epidemic, there is a need to identify factors that predict aberrant opioid behaviors including misuse and abuse. Impulsivity has been extensively studied in addiction literature, but not in the context of opioid misuse. Hence, this study aimed to identify which of the impulsivity facets (negative urgency, positive urgency, sensation seeking, lack of perseverance, and lack of premeditation) would predict current aberrant opioid-related behaviors in patients with chronic pain.METHODS: Data were collected through an online survey from patients with chronic pain who visited a tertiary pain clinic. Patients were predominately female (74%), middle aged (M=55years), and White/Caucasian (84%). Upon consent, they completed a series of surveys including UPPS-P Impulsive Behavior Scale, the Current Opioid misuse Measure, Pain Catastrophizing Scale, PROMIS-anxiety, depression, and physical function, and a 0-10 numerical pain rating scale. Ordinal regression analyses were conducted to test study hypotheses.RESULTS: Contrary to expectations, only lack of premeditation predicted higher odds of aberrant opioid-related behaviors in the past 30days, after controlling for known covariates, and explained 26% of variance. Interestingly, lack of premeditation together with pain catastrophizing as a covariate explained 56% of the variance in aberrant opioid-related behaviors.DISCUSSION: The current study is the first to identify a potential role of lack of premeditation as an impulsivity facet predicting aberrant opioid-related behaviors among patients with chronic pain.

  • Comparative efficacy of a single-session "Empowered Relief" videoconference-delivered group intervention for chronic pain: study protocol for a randomized controlled trial. Trials Ziadni, M. S., Anderson, S. R., Gonzalez-Castro, L., Darnall, B. D. 2021; 22 (1): 358

    Abstract

    BACKGROUND: Chronic pain is naturally aversive and often distressing for patients. Pain coping and self-regulatory skills have been shown to effectively reduce pain-related distress and other symptoms. In this trial, the primary goal is to pilot test the comparative efficacy of a single-session videoconference-delivered group pain education class to a waitlist control among patients with chronic pain.METHODS: Our study is a randomized clinical trial pilot testing the superiority of our 2-h single-session videoconference-delivered group pain education class against a waitlist control. We will enroll 120 adult patients with mixed etiology chronic pain and randomize 1:1 to one of the two study arms. We hypothesize superiority for the pain education class for bolstering pain and symptom management. Team researchers masked to treatment assignment will assess the outcomes up to 3 months post-treatment.DISCUSSION: This study aims to test the utility of a single-session videoconference-delivered group pain education class to improve self-regulation of pain and pain-related outcomes. Findings from our project have the potential to significantly reduce barriers to effective psychological treatment for pain, optimizing the delivery of increasingly vital online and remote-delivered intervention options.TRIAL REGISTRATION: ClinicalTrials.gov NCT04546685 .

  • Customizing CAT administration of the PROMIS Misuse of Prescription Pain Medication Item Bank for patients with chronic pain. Pain medicine (Malden, Mass.) You, D. S., Cook, K. F., Domingue, B. W., Ziadni, M. S., Hah, J. M., Darnall, B. D., Mackey, S. C. 2021

    Abstract

    OBJECTIVE: The 22-item PROMIS-Rx Pain Medication Misuse item bank (Bank-22) imposes a high response burden. This study aimed to characterize the performance of the Bank-22 in a computer adaptive testing (CAT) setting based on varied stopping rules.METHODS: The 22 items were administered to 288 patients. We performed a CAT simulation using default stopping rules (CATPROMIS). In 5 other simulations, a "best health" response rule was added to decrease response burden. This rule stopped CAT administration when a participant selected "never" to a specified number of initial Bank-22 items (2-6 in this study, designated CATAlt2-Alt6). The Bank-22 and 7-item short form (SF-7) scores were compared to scores based on CATPROMIS, and the 5 CAT variations.RESULTS: Bank-22 scores correlated highly with the SF-7 and CATPROMIS, Alt5, Alt6 scores (rs=.87-.95) and moderately with CATAlt2- Alt4 scores (rs=.63-.74). In all CAT conditions, the greatest differences with Bank-22 scores were at the lower end of misuse T-scores. The smallest differences with Bank-22 and CATPROMIS scores were observed with CATAlt5 and CATAlt6. Compared to the SF-7, CATAlt5 and CATAlt6 reduced overall response burden by about 42%. Finally, the correlations between PROMIS-Rx Misuse and Anxiety T-scores remained relatively unchanged across the conditions (rs=.31-.43, ps < .001).CONCLUSIONS: Applying a stopping rule based on number of initial "best health" responses reduced response burden for respondents with lower levels of misuse. The tradeoff was less measurement precision for those individuals, which could be an acceptable tradeoff when the chief concern is in discriminating higher levels of misuse.

    Abstract

    Introduction: Critical for the diagnosis and treatment of chronic pain is the anatomical distribution of pain. Several body maps allow patients to indicate pain areas on paper; however, each has its limitations.Objectives: To provide a comprehensive body map that can be universally applied across pain conditions, we developed the electronic Collaborative Health Outcomes Information Registry (CHOIR) self-report body map by performing an environmental scan and assessing existing body maps.Methods: After initial validation using a Delphi technique, we compared (1) pain location questionnaire responses of 530 participants with chronic pain with (2) their pain endorsements on the CHOIR body map (CBM) graphic. A subset of participants (n = 278) repeated the survey 1 week later to assess test-retest reliability. Finally, we interviewed a patient cohort from a tertiary pain management clinic (n = 28) to identify reasons for endorsement discordances.Results: The intraclass correlation coefficient between the total number of body areas endorsed on the survey and those from the body map was 0.86 and improved to 0.93 at follow-up. The intraclass correlation coefficient of the 2 body map graphics separated by 1 week was 0.93. Further examination demonstrated high consistency between the questionnaire and CBM graphic (<10% discordance) in most body areas except for the back and shoulders (15-19% discordance). Participants attributed inconsistencies to misinterpretation of body regions and laterality, the latter of which was addressed by modifying the instructions.Conclusions: Our data suggest that the CBM is a valid and reliable instrument for assessing the distribution of pain.

  • Comparison of a Single-Session Pain Management Skills Intervention With a Single-Session Health Education Intervention and 8 Sessions of Cognitive Behavioral Therapy in Adults With Chronic Low Back Pain: A Randomized Clinical Trial. JAMA network open Darnall, B. D., Roy, A., Chen, A. L., Ziadni, M. S., Keane, R. T., You, D. S., Slater, K., Poupore-King, H., Mackey, I., Kao, M. C., Cook, K. F., Lorig, K., Zhang, D., Hong, J., Tian, L., Mackey, S. C. 2021; 4 (8): e2113401

    Abstract

    Chronic low back pain (CLBP), the most prevalent chronic pain condition, imparts substantial disability and discomfort. Cognitive behavioral therapy (CBT) reduces the effect of CLBP, but access is limited.To determine whether a single class in evidence-based pain management skills (empowered relief) is noninferior to 8-session CBT and superior to health education at 3 months after treatment for improving pain catastrophizing, pain intensity, pain interference, and other secondary outcomes.This 3-arm randomized clinical trial collected data from May 24, 2017, to March 3, 2020. Participants included individuals in the community with self-reported CLBP for 6 months or more and an average pain intensity of at least 4 (range, 0-10, with 10 indicating worst pain imaginable). Data were analyzed using intention-to-treat and per-protocol approaches.Participants were randomized to (1) empowered relief, (2) health education (matched to empowered relief for duration and format), or (3) 8-session CBT. Self-reported data were collected at baseline, before treatment, and at posttreatment months 1, 2, and 3.Group differences in Pain Catastrophizing Scale scores and secondary outcomes at month 3 after treatment. Pain intensity and pain interference were priority secondary outcomes.A total of 263 participants were included in the analysis (131 women [49.8%], 130 men [49.4%], and 2 other [0.8%]; mean [SD] age, 47.9 [13.8] years) and were randomized into 3 groups: empowered relief (n = 87), CBT (n = 88), and health education (n = 88). Empowered relief was noninferior to CBT for pain catastrophizing scores at 3 months (difference from CBT, 1.39 [97.5% CI, -∞ to 4.24]). Empowered relief and CBT were superior to health education for pain catastrophizing scores (empowered relief difference from health education, -5.90 [95% CI, -8.78 to -3.01; P < .001]; CBT difference from health education, -7.29 [95% CI, -10.20 to -4.38; P < .001]). Pain catastrophizing score reductions for empowered relief and CBT at 3 months after treatment were clinically meaningful (empowered relief, -9.12 [95% CI, -11.6 to -6.67; P < .001]; CBT, -10.94 [95% CI, -13.6 to -8.32; P < .001]; health education, -4.60 [95% CI, -7.18 to -2.01; P = .001]). Between-group comparisons for pain catastrophizing at months 1 to 3 were adjusted for baseline pain catastrophizing scores and used intention-to-treat analysis. Empowered relief was noninferior to CBT for pain intensity and pain interference (priority secondary outcomes), sleep disturbance, pain bothersomeness, pain behavior, depression, and anxiety. Empowered relief was inferior to CBT for physical function.Among adults with CLBP, a single-session pain management class resulted in clinically significant improvements in pain catastrophizing, pain intensity, pain interference, and other secondary outcomes that were noninferior to 8-session CBT at 3 months.ClinicalTrials.gov Identifier: NCT03167086.

  • Effectiveness of a multidisciplinary rehabilitation program in real-world patients with chronic back pain: A pilot cohort data analysis JOURNAL OF BACK AND MUSCULOSKELETAL REHABILITATION You, D. S., Ziadni, M. S., Cooley, C. E., Talavera, D. C., Mackey, S. C., Poupore-King, H. 2021; 34 (6): 965-973

    Abstract

    Randomized clinical trials (RCT) suggest a multidisciplinary approach to pain rehabilitation is superior to other active treatments in improving pain intensity, function, disability, and pain interference for patients with chronic pain, with small effect size (ds= 0.20-0.36) but its effectiveness remains unknown in real-world practice.The current study examined the effectiveness of a multidisciplinary program to a cognitive and behavioral therapy (pain-CBT) in real-world patients with chronic back pain.Twenty-eight patients (M𝑎𝑔𝑒= 57.6, 82.1% Female) completed a multidisciplinary program that included pain psychology and physical therapy. Eighteen patients (M𝑎𝑔𝑒= 58.9, 77.8% Female) completed a CBT-alone program. Using a learning healthcare system, the Pain Catastrophizing Scale, 0-10 Numerical Pain Rating Scale, and Patient-Reported Outcomes Measurement Information System® measures were administered before and after the programs.We found significant improvement in mobility and pain behavior only after a multidisciplinary program (p's < 0.031; d= 0.69 and 0.55). We also found significant improvement in pain interference, fatigue, depression, anxiety, social role satisfaction, and pain catastrophizing after pain-CBT or multidisciplinary programs (p's < 0.037; ds = 0.29-0.73). Pain ratings were not significantly changed by either program (p's > 0.207).The effect of a multidisciplinary rehabilitation program observed in RCT would be generalizable to real-world practice.

  • Efficacy of a Single-Session "Empowered Relief" Zoom-Delivered Group Intervention for Chronic Pain: Randomized Controlled Trial Conducted During the COVID-19 Pandemic. Journal of medical Internet research Ziadni, M. S., Gonzalez-Castro, L., Anderson, S., Krishnamurthy, P., Darnall, B. D. 2021; 23 (9): e29672

    Abstract

    Cognitive behavioral therapy-pain is an evidence-based treatment for chronic pain that can have significant patient burden, including health care cost, travel, multiple sessions, and lack of access in remote areas.The study aims to pilot test the efficacy of a single-session videoconference-delivered empowered relief (ER) intervention compared to waitlist control (WLC) conditions among individuals with chronic pain. We hypothesized that ER would be superior to WLC in reducing pain catastrophizing, pain intensity, and other pain-related outcomes at 1-3 months posttreatment.We conducted a randomized controlled trial involving a web-based sample of adults (N=104) aged 18-80 years with self-reported chronic pain. Participants were randomized (1:1) to 1 of 2 unblinded study groups: ER (50/104, 48.1%) and WLC (54/104, 51.9%). Participants allocated to ER completed a Zoom-delivered class, and all participants completed follow-up surveys at 2 weeks and 1, 2, and 3 months posttreatment. All the study procedures were performed remotely and electronically. The primary outcome was pain catastrophizing 1-month posttreatment, with pain intensity, pain bothersomeness, and sleep disruption as secondary outcomes. We also report a more rigorous test of the durability of treatment effects at 3 months posttreatment. Data were collected from September 2020 to February 2021 and analyzed using intention-to-treat analysis. The analytic data set included participants (18/101, 17.8% clinic patients; 83/101, 82.1% community) who completed at least one study survey: ER (50/101, 49.5%) and WLC (51/104, 49%).Participants (N=101) were 69.3% (70/101) female, with a mean age of 49.76 years (SD 13.90; range 24-78); 32.7% (33/101) had an undergraduate degree and self-reported chronic pain for 3 months. Participants reported high engagement (47/50, 94%), high satisfaction with ER (mean 8.26, SD 1.57; range 0-10), and high satisfaction with the Zoom platform (46/50, 92%). For the between-groups factor, ER was superior to WLC for all primary and secondary outcomes at 3 months posttreatment (highest P<.001), and between-groups Cohen d effect sizes ranged from 0.45 to 0.79, indicating that the superiority was of moderate to substantial clinical importance. At 3 months, clinically meaningful pain catastrophizing scale (PCS) reductions were found for ER but not for WLC (ER: PCS -8.72, 42.25% reduction; WLC: PCS -2.25, 11.13% reduction). ER resulted in significant improvements in pain intensity, sleep disturbance, and clinical improvements in pain bothersomeness.Zoom-delivered ER had high participant satisfaction and very high engagement. Among adults with chronic pain, this single-session, Zoom-delivered, skills-based pain class resulted in clinically significant improvement across a range of pain-related outcomes that was sustained at 3 months. Web-based delivery of ER could allow greater accessibility of home-based pain treatment and could address the inconveniences and barriers faced by patients when attempting to receive in-person care.ClinicalTrials.gov NCT04546685; https://clinicaltrials.gov/ct2/show/NCT04546685.

  • Validation of CARE Scale-7 in treatment-seeking patients with chronic pain: measurement of sex invariance. Pain reports Ziadni, M., You, D. S., Chen, A., Wilson, A. C., Darnall, B. D. 2020; 5 (6): e862

    Abstract

    Objectives: Social and interpersonal factors impact the trajectory of chronic pain. We previously developed and validated a 2-factor, 7-item measure to assess interpersonal factors, including relationship guilt and worry and difficulty prioritizing self-care in chronic pain. Here, we confirm the factor structure and examine the sex invariance of the two-factor structure of the CARE Scale-7.Methods: Data were collected as part of routine clinical care at a tertiary pain clinic using the Collaborative Health Outcomes Information Registry. Patient participants (67% women) were predominantly middle-aged (M = 50.9 years, SD = 17.8), married (55.2%), and White/non-Hispanic (55.7%). Data included demographics, pain characteristics, CARE Scale-7, pain catastrophizing, and Patient-Reported Outcomes Measurement Information System psychological and physical function measures. Confirmatory factor analysis was conducted to validate the factor structure of the CARE Scale, and a stepwise approach to measurement invariances by sex examined configural, metric, and scalar invariance.Results: Internal consistency of the scale items ensured suitability for factor analyses. Confirmatory factor analysis findings revealed an overall good fit of the 2-factor model among males and females and that CARE Scale-7 is in fact sex invariant. Finally, CARE Scale-7 showed convergent validity with pain-related outcomes.Discussion: The CARE Scale is the first validated instrument to assess self-care in both sexes among patients with chronic pain. The subscale of difficulty prioritizing self-care emerged as a potentially unique factor that should be integrated in clinical assessment. CARE Scale may facilitate standardized measurement in research and clinical contexts, which may inform a comprehensive treatment focus that integrates individualized self-care planning.

  • Association of State Policies Allowing Medical Cannabis for Opioid Use Disorder With Dispensary Marketing for This Indication. JAMA network open Shover, C. L., Vest, N. A., Chen, D., Stueber, A., Falasinnu, T. O., Hah, J. M., Kim, J., Mackey, I., Weber, K. A., Ziadni, M., Humphreys, K. 2020; 3 (7): e2010001

    Abstract

    Importance: Misinformation about cannabis and opioid use disorder (OUD) may increase morbidity and mortality if it leads individuals with OUD to forego evidence-based treatment. It has not been systematically evaluated whether officially designating OUD as a qualifying condition for medical cannabis is associated with cannabis dispensaries suggesting cannabis as a treatment for OUD.Objective: To examine whether state-level policies designating OUD a qualifying condition for medical cannabis are associated with more dispensaries claiming cannabis can treat OUD.Design, Setting, and Participants: This cross-sectional, mixed-methods study of 208 medical dispensary brands was conducted in 2019 using the brands' online content. The study included dispensaries operating in New Jersey, New York, and Pennsylvania, where OUD is a qualifying condition for medical cannabis, and in Connecticut, Delaware, Maryland, Ohio, and West Virginia, where this policy does not exist.Exposures: Presence of OUD on the list of qualifying conditions for a state's medical cannabis program.Main Outcomes and Measures: Binary indicators of whether online content from the brand said cannabis can treat OUD, can replace US Food and Drug Administration-approved medications for OUD, can be an adjunctive therapy to Food and Drug Administration-approved medications for OUD, or can be used as a substitute for opioids to treat other conditions (eg, chronic pain).Results: After excluding duplicates, listings for nonexistent dispensaries, and those without online content, 167 brands across 7 states were included in the analysis (44 [26.3%] in states where OUD was a qualifying condition and 123 [73.7%] in adjacent states). A dispensary listed in a directory for West Virginia was not operational; therefore, comparison states were Connecticut, Delaware, Maryland, and Ohio. In policy-exposed states, 39% (95% CI, 23%-55%) more dispensaries claimed cannabis could treat OUD compared with unexposed states (P<.001). For replacing medications for OUD and being an adjunctive therapy, the differences were 14% (95% CI, 2%-26%; P=.002) and 28% (95% CI, 14%-42%; P<.001), respectively. The suggestion that cannabis could substitute for opioids (eg, to treat chronic pain) was made by 25% (95% CI, 9%-41%) more brands in policy-exposed states than adjacent states (P=.002).Conclusions and Relevance: In this study, state-level policies designating OUD as a qualifying condition for medical cannabis were associated with more dispensaries claiming cannabis can treat OUD. In the current policy environment, in which medical claims by cannabis dispensaries are largely unregulated, these advertisements could harm patients. Future research linking these policies to patient outcomes is warranted.

  • Perceived Injustice Mediates the Relationship Between Perceived Childhood Neglect and Current Function in Patients with Chronic Pain: A Preliminary Pilot Study. Journal of clinical psychology in medical settings Ziadni, M. S., You, D. S., Sturgeon, J. A., Mackey, S. C., Darnall, B. D. 2020

    Abstract

    Cumulative evidence supports the association between perceived childhood neglect and adulthood psychological and physical health. To date, pathways mediating this association remain largely unknown, though other evidence suggests that negative patterns of appraisal, including injustice perception related to pain, may be shaped by prior adverse social experiences. Consequently, the current study examined perceived injustice about chronic pain as a possible factor connecting childhood neglect and pain-related outcomes, given its relevance for both adaptation to chronic pain and to prior adverse life experiences. Patients (n = 742) visiting a tertiary pain clinic completed a survey administered via the Collaborative Health Outcomes Information Registry. Path modeling analyses were used to examine perceived injustice as a mediator of the relationships between childhood neglect and affective distress and physical function, after controlling for pain intensity and pain catastrophizing. Patients endorsing childhood neglect reported higher levels of perceived injustice and worse affective distress and physical function. Further, inclusion of perceived injustice as a mediator fully accounted for the relationship between neglect and current levels of physical function, and accounted for a significant proportion of the relationship between neglect and current levels of affective distress. These preliminary findings suggest that perceived injustice appears to be a more proximal factor by which prior experiences of neglect may adversely affect adaptation to chronic pain. Given the single-item assessment of childhood neglect and cross-sectional nature of the current findings, further research may focus on replicating these findings in longitudinal studies with validated measures and examining other adverse social experiences (e.g., abuse, social disparities) that may contribute to injustice perception and poor pain-related outcomes.

  • Efficacy and mechanisms of a single-session behavioral medicine class among patients with chronic pain taking prescription opioids: study protocol for a randomized controlled trial. Trials Ziadni, M. S., Chen, A. L., Winslow, T. n., Mackey, S. C., Darnall, B. D. 2020; 21 (1): 521

    Abstract

    Independent of pain intensity, pain-specific distress is highly predictive of pain treatment needs, including the need for prescription opioids. Given the inherently distressing nature of chronic pain, there is a need to equip individuals with pain education and self-regulatory skills that are shown to improve adaptation and improve their response to medical treatments. Brief, targeted behavioral medicine interventions may efficiently address the key individual factors, improve self-regulation in the context of pain, and reduce the need for opioid therapy. This highlights the critical need for targeted, cost-effective interventions that efficiently address the key psychological factors that can amplify the need for opioids and increased risk for misuse. In this trial, the primary goal is to test the comparative efficacy of a single-session skills-based pain management class to a health education active control group among patients with chronic pain who are taking opioids.Our study is a randomized, double-blind clinical trial testing the superiority of our 2-h, single-session skills-based pain management class against a 2-h health education class. We will enroll 136 adult patients with mixed-etiology chronic pain who are taking opioid prescription medication and randomize 1:1 to one of the two treatment arms. We hypothesize superiority for the skills-based pain class for pain control, self-regulation of pain-specific distress, and reduced opioid use measured by daily morphine equivalent. Team researchers masked to treatment assignment will assess outcomes up to 12 months post treatment.This study aims to test the utility of a single-session, 2-h skills-based pain management class to improve self-regulation of pain and reduce opioid use. Findings from our project have the potential to shift current research and clinical paradigms by testing a brief and scalable intervention that could reduce the need for opioids and prevent misuse effectively, efficiently, and economically. Further, elucidation of the mechanisms of opioid use can facilitate refinement of more targeted future treatments.ClinicalTrials.gov, ID: NCT03950791. Registered on 10 May 2019.

    Abstract

    Emotional approach coping (EAC) is a potentially adaptive emotion-focused coping style that involves understanding or processing one's emotions and expressing them appropriately. Although EAC has been studied in various populations, little is known about this construct among people with chronic pain, including potential mediators such as negative affect, which might link EAC to pain-related variables, and moderators of these relationships.Participants (N = 670; 76% women; 30% older adults-age 60 or over) with chronic pain completed online the Emotional Approach Coping Scale and measures of pain severity, pain interference, and negative affect. Analyses correlated EAC to pain severity and interference and tested whether gender and age group (older adults vs. young/middle-age adults) moderated the mediated relationships of EAC with pain-related variables through negative affect.Findings reveal that higher EAC was associated with lower pain intensity through lower negative affect in the young/middle-age portion of the sample, but not older adults. Also, higher EAC was associated with lower pain interference through lower negative affect among women in the sample, but not men. The associations of EAC to pain intensity and interference are small in magnitude, however, and should be considered preliminary.EAC is associated with lower pain intensity in young/middle-age adults and lower pain interference in women, and lower negative affect mediates these relationships. These results suggest the potential value of assessing and bolstering emotional approach coping processes in some people with chronic pain.

    Abstract

    OBJECTIVE: This study aims to assess the feasibility of digital perioperative behavioral pain medicine intervention in breast cancer surgery and evaluate its impact on pain catastrophizing, pain, and opioid cessation after surgery.DESIGN AND SETTING: A randomized controlled clinical trial was conducted at Stanford University (Palo Alto, CA, USA) comparing a digital behavioral pain medicine intervention ("My Surgical Success" [MSS]) with digital general health education (HE).PARTICIPANTS: A convenience sample of 127 participants were randomized to treatment group. The analytic sample was 68 patients (N=36 MSS, N=32 HE).MAIN OUTCOMES: The primary outcome was feasibility and acceptability of a digital behavioral pain medicine intervention (80% threshold for acceptability items). Secondary outcomes were pain catastrophizing, past seven-day average pain intensity, and time to opioid cessation after surgery for patients who initiated opioid use.RESULTS: The attrition rate for MSS intervention (44%) was notably higher than for HE controls (18%), but it was lower than typical attrition rates for e-health interventions (60-80%). Despite greater attrition for MSS, feasibility was demonstrated for the 56% of MSS engagers, and the 80% threshold for acceptability was met. We observed a floor effect for baseline pain catastrophizing, and no significant group differences were found for postsurgical pain catastrophizing or pain intensity. MSS was associated with 86% increased odds of opioid cessation within the 12-week study period relative to HE controls (hazard ratio = 1.86, 95% confidence interval = 1.12-3.10, P=0.016).CONCLUSIONS: Fifty-six percent of patients assigned to MSS engaged with the online platform and reported high satisfaction. MSS was associated with significantly accelerated opioid cessation after surgery (five-day difference) with no difference in pain report relative to controls. Perioperative digital behavioral pain medicine may be a low-cost, accessible adjunct that could promote opioid cessation after breast cancer surgery.

    Abstract

    OBJECTIVE: The National Institutes of Health's Patient-Reported Outcomes Measurement Information System (PROMIS) includes an item bank for measuring misuse of prescription pain medication (PROMIS-Rx Misuse). The bank was developed and its validity evaluated in samples of community-dwelling adults and patients in addiction treatment programs. The goal of the current study was to investigate the validity of the item bank among patients with mixed-etiology chronic pain conditions.METHOD: A consecutive sample of 288 patients who presented for initial medical evaluations at a tertiary pain clinic completed questionnaires using the open-source Collaborative Health Outcomes Information Registry. Participants were predominantly middle-aged (M [SD]=51.6 [15.5] years), female (62.2%), and white/non-Hispanic (51.7%). Validity was evaluated by estimating the association between PROMIS-Rx Misuse scores and scores on other measures and testing the ability of scores to distinguish among risk factor subgroups expected to have different levels of prescription pain medicine misuse (known groups analyses).RESULTS: Overall, score associations with other measures were as expected and scores effectively distinguished among patients with and without relevant risk factors.CONCLUSION: The study results supported the preliminary validity of PROMIS-Rx Misuse item bank scores for the assessment of prescription opioid misuse in patients visiting an outpatient pain clinic.

  • Perceived lack of training moderates relationship between healthcare providers' personality and sense of efficacy in trauma-informed care. Anxiety, stress, and coping Stevens, N. R., Ziadni, M. S., Lillis, T. A., Gerhart, J. n., Baker, C. n., Hobfoll, S. E. 2019: 1–15

    Abstract

    Medical patients often have trauma histories that are not routinely assessed, which can adversely affect health outcomes. Despite growing awareness of this issue, there is limited understanding of factors that influence provider competency in trauma-informed care (TIC). The study examined healthcare providers' personality traits in relation to their sense of TIC efficacy, taking into account perceived barriers to TIC and professional quality of life.The study used cross-sectional survey methods to examine our central hypothesis that provider personality traits and perceived barriers to TIC would be associated with TIC-efficacy, and to explore interactions among study variables.Survey data were collected from 172 healthcare providers examining TIC knowledge, TIC-efficacy, perceived barriers to TIC, personality traits, and professional quality of life.TIC-efficacy was positively correlated with "intellectence/openness" and inversely correlated with "neuroticism" and perceived lack of training as a barrier. "Intellectence/openness" interacted with perceived lack of training to predict TIC-efficacy, suggesting that providers with lower "intellectence/openness" report greater TIC-efficacy when lack of training is not perceived as a barrier.Provider personality traits and perceived barriers to TIC appear related to providers' TIC-efficacy. Implications for overcoming barriers to TIC through training and implementation are discussed.

  • Injustice Appraisal but not Pain Catastrophizing Mediates the Relationship Between Perceived Ethnic Discrimination and Depression and Disability in Low Back Pain. The journal of pain : official journal of the American Pain Society Ziadni, M. S., Sturgeon, J. A., Bissell, D. n., Guck, A. n., Martin, K. J., Scott, W. n., Trost, Z. n. 2019

    Abstract

    Despite growing evidence of significant racial disparities in the experience and treatment of chronic pain, the mechanisms by which these disparities manifest have remained relatively understudied. The current study examined the relationship between past experiences of racial discrimination and pain-related outcomes (self-rated disability and depressive symptomatology), and tested the potential mediating roles of pain catastrophizing and perceived injustice related to pain. Analyses consisted of cross-sectional path modeling in a multiracial sample of 137 individuals with chronic low back pain (Hispanics N=43; Blacks N=43; Whites N=51). Results indicated a positive relationship between prior discriminatory experiences and severity of disability and depressive symptoms. In mediation analyses, pain-related appraisals of injustice, but not pain catastrophizing, were found to mediate these relationships. Notably, the association between discrimination history and perceived injustice was significantly stronger in Black and Hispanic participants and was not statistically significant in White participants. The findings suggest that race-based discriminatory experiences may contribute to racial disparities in pain outcomes and highlight the specificity of pain-related, injustice-related appraisals as a mechanism by which these experiences may impair physical and psychosocial function. Future research is needed to investigate temporal and causal mechanisms suggested by the model through longitudinal and clinical intervention studies. PERSPECTIVE: More frequent prior experiences of racial discrimination are associated with greater depressive symptomatology and pain-related disability in individuals with chronic low back pain. These associations are explained by the degree of injustice perception related to pain, but not pain catastrophizing, and were stronger among Black and Hispanic participants.

    Abstract

    Post-traumatic Stress Disorder (PTSD) commonly co-occurs with chronic pain. Although PTSD symptoms are associated with negative health outcomes in patients with chronic pain, PTSD is typically under-detected and under-treated in outpatient pain settings. There is a need for rapid, brief screening tools to identify those at greatest risk for severe PTSD symptoms. To achieve that goal, our aim was to use item response theory (IRT) to identify the most informative PTSD symptoms characterizing severe PTSD in patients with chronic pain.Fifty-six patients (71% female, 61% White) with mixed etiology chronic pain completed the PTSD Checklist Civilian Version (PCL-C) as part of their appointment with a pain psychologist at a tertiary outpatient pain clinic. We used an IRT approach to evaluate each item's discriminant (a) and severity (b) parameters.Findings revealed that 'feeling upset at reminders' (a = 3.67, b = 2.44) and 'avoid thinking or talking about it' (a = 3.61, b = 2.17) as being highly discriminant for severe PTSD.We identified two candidate items for a brief PTSD screener as they were associated with severe PTSD symptoms. These two items may provide clinical utility in outpatient pain treatment settings to identify those suffering from severe PTSD enabling physicians to refer them to trauma-specific evaluation or therapy. Future research is needed to further validate and confirm these candidate PTSD items in a larger clinic sample.

    Abstract

    Introduction: Chronic pain in late adolescence and young adults is understudied and poorly characterized.Objectives: We sought to characterize key variables that may impact pain interference in late adolescents and young adults with chronic pain, including prescription opioid use, marijuana use, psychological symptoms, and obesity.Methods: Retrospective, cross-sectional medical chart review for patients aged 17 to 23 years (N = 283; 61% Females) seeking care at a tertiary care pain clinic. Data on pain characteristics, health behaviors, and mental health distress were examined, in addition to self-reported pain intensity and interference.Results: Overlapping pain conditions were common in this young adult sample (mean ≥ 2 pain conditions). Back pain was the most commonly cited pain condition, and the majority of pain was of unknown etiology. Results revealed high rates for current opioid prescription, overweight or obese status, and mental health problems. Those using prescription opioids were more likely to endorse tobacco use and had greater pain interference. Importantly, the presence of mental health distress and opioid use were predictive of higher levels of pain-related interference.Conclusion: Treatment-seeking adolescents and young adults with chronic pain evidence complex care needs that include pain and mental comorbidities, as well as risky health behaviors. Pain and mental health distress were associated with poorer physical health, opioid prescription and marijuana use, and pain-related interference. Findings underscore the need for additional research on pain, treatment patterns, and health behaviors and their impact on developmental trajectories, as well as the need to develop and apply effective early interventions in this at-risk population.

  • Sleep quality buffers the effects of negative social interactions on maternal mood in the 3-6month postpartum period: a daily diary study. Journal of behavioral medicine Lillis, T. A., Hamilton, N. A., Pressman, S. D., Ziadni, M. S., Khou, C. S., Boddy, L. E., Wagner, L. M. 2018; 41 (5): 733–46

    Abstract

    Sleep and social relationships are two key determinants of psychosocial health that undergo considerable change across the transition to motherhood. The current study investigated the bidirectional relationship between daytime Positive and Negative Social Interactions (PSIs & NSIs) and nighttime sleep quality on maternal mood across 1week in the 3-6month postpartum period. Sixty healthy, non-depressed first-time mothers completed 7-consecutive days of daily social interaction and sleep diaries. Results indicated that higher than average sleep quality buffered the effect of higher than average NSIs on maternal mood (i.e., buffered mood reactivity) and appeared to promote mood recovery following a particularly "bad day" (i.e., higher than average NSIs). In addition, although PSIs were more common than NSIs overall, the most frequent and positively rated PSIs were with baby as were the most frequent and negatively rated NSIs. To our knowledge, our results are the first to characterize the impact of PSIs on postpartum maternal mood, assess maternal-infant social interactions in daily diary study of postpartum social relationships, and demonstrate the role that maternal sleep quality plays in social discord-related mood reactivity and mood recovery processes in the 3-6month postpartum period.

    Abstract

    Introduction: Unsafe opioid prescribing practices to treat acute and chronic pain continue to contribute to the opioid overdose crisis in the United States, a growing public health emergency that harms patients and their communities. Poor opioid prescribing practices stem in part from a lack of education and skills training surrounding pain and opioid management.Methods: As part of the Clinical Pain Medicine Fellowship at Stanford University, physicians were given the opportunity to participate in a pilot program to practice opioid management in a live, simulated interaction. Twenty-seven physician trainees participated in the simulation with a live, standardized patient actor. Before beginning the simulation, participants were given a detailed patient history that included the patient's risk for opioid abuse. They were also provided with relevant risk evaluation and mitigation (REM) tools. All simulation interactions were video-recorded and coded by two independent reviewers. A detailed coding scheme was developed before video analysis, and an inter-rater reliability score showed substantial agreement between reviewers.Results: Contrary to expectations, many of the observed performances by trainees contained aspects of unsafe opioid prescribing, given the patient history. Many trainees did not discuss their patient's aberrant behaviors related to opioids or the patient's risk for opioid abuse. Marked disparities were also observed between the trainees' active patient interactions and their written progress notes.Discussion: This simulation addresses a pressing need to further educate, train, and provide point-of-care tools for providers prescribing opioids. We present our experience and preliminary findings.

  • Examining injustice appraisals in a racially diverse sample of individuals with chronic low back pain. The journal of pain : official journal of the American Pain Society Trost, Z., Sturgeon, J., Guck, A., Ziadni, M., Nowlin, L., Goodin, B., Scott, W. 2018

    Abstract

    Injustice perception has emerged as a risk factor for problematic musculoskeletal pain outcomes. Despite the prevalence and impact of chronic low back pain (CLBP) no study has addressed injustice appraisals specifically among individuals with CLBP. In addition, despite racial/ethnic disparities in pain, existing injustice research has relied almost exclusively on White/Caucasian participant samples. The current study examined associations between perceived injustice and pain, disability, and depression in a diverse community sample of individuals with CLBP (N=137) - 51(37.2%) White, 43(31.4%) Hispanic, 43(31.4%) Black or African American). Anger variables were tested as potential mediators of these relationships. Controlling for demographic and pain-related covariates, perceived injustice accounted for unique variance in self-reported depression and disability outcomes, but not pain intensity. State and trait anger, and anger inhibition mediated association between perceived injustice and depression; no additional mediation by anger was observed. Significant racial differences were also noted. Compared to White and Hispanic participants, Black participants reported higher levels of perceived injustice related to CLBP, as well as higher depression, and pain-related disability. Black participants also reported higher pain intensity than White participants. Current findings provide initial evidence regarding the role of injustice perception specifically in the context of CLBP and within a racially diverse participant sample. Results highlight the need for greater diversity within injustice and CLBP research as well as research regarding socially-informed antecedents of injustice appraisals.PERSPECTIVE: Perceived injustice predicted worse outcomes in chronic low back pain, with effects partially mediated by anger. Black participants reported worse pain outcomes and higher injustice perception than White or Hispanic counterparts. Given racial inequities within broader health and pain-specific outcomes, this topic is critical for CLBP and perceived injustice research.

  • CARE Scale - 7: Development and Preliminary Validation of a Measure to Assess Factors Impacting Self-care in Chronic Pain. The Clinical journal of pain Ziadni, M., You, D. S., Wilson, A. C., Darnall, B. D. 2018

    Abstract

    Social and interpersonal factors may impact chronic pain self-care and self-management; however, no integrated measure exists to assess the interplay of these factors. We developed and tested a measure designed to assess salient interpersonal factors, including relationship guilt and worry, and difficulty prioritizing self-care in chronic pain.We tested self-report items broadly relevant to locus of care, limit-setting capacity, and worry/guilt about relationships in 3 discrete chronic pain samples (total N=1,452): (1) online sample of chronic pain clinic patients (N=729; 21 candidate CARE items, sociodemographics, and measures of psychological and physical functioning). Analytic results supported a final 7-item CARE Scale which was next tested in (2) an anonymous online sample of 578 adults with chronic pain. (3) Finally, preliminary validation of the CARE Scale was performed in a tertiary pain clinic sample (N=145).Exploratory factor analysis revealed a 7-item, 2-factor solution (difficulty prioritizing self-care and guilt/worry) that accounted for a combined total of 58% of the variance. CARE Scale-7 had modest convergent validity with pain intensity, pain-related interference, and emotional distress. Extreme difficulty with both factors was reported by about one-third of the total sample, suggesting that relationship factors significantly impact pain management and self-care.Social factors are gaining attention for their influence on the trajectory of chronic pain. The CARE Scale is a brief, integrated measure that may be used to reveal specific interpersonal and personal impediments to self-care, and identify important therapeutic targets to optimize self-management behaviors.

    Abstract

    The Institute of Medicine (IOM) reported that chronic pain affects about 100 million U.S. adults, with chronic low back pain (CLBP) cited as the most prevalent type. Pain catastrophizing is a psychological construct shown to predict the development and trajectory of chronic pain and patient response to pain treatments. While effective treatment for pain catastrophizing typically includes eight-session groups of cognitive behavioral therapy (CBT), a single-session targeted treatment class yielded promising results which, if replicated and extended, could prove to efficiently and cost-effectively reduce pain catastrophizing. In this trial, we seek to determine the comparative efficacy of this novel single-session pain catastrophizing class to an eight-session course of pain CBT and a single-session back pain health education class. We will also explore the psychosocial mechanisms and outcomes of pain catastrophizing treatment.In this trial we will randomize 231 individuals with CLBP to one of three treatment arms: (1) pain-CBT (eight weekly 2-h group sessions with home exercises and readings); (2) a single 2-h pain catastrophizing class; or (3) a single 2-h back pain health education class (active control). For the primary outcome of pain catastrophizing, the trial is designed as a non-inferiority test between pain-CBT and the single-session pain catastrophizing class, and as a superiority test between the single-session pain catastrophizing class and the health education class. Team researchers masked to treatment assignment will assess outcomes up to six months post treatment.If the single-session targeted pain catastrophizing class is found to be an effective treatment for patients with CLBP, this low cost and low burden treatment could dismantle many of the current barriers and burdens of effective pain care. Further, elucidation of the mechanisms of pain catastrophizing treatments will facilitate future research on the topic as well as further development and refinement of treatments.ClinicalTrials.gov, NCT03167086 .

  • A Life-Stress, Emotional Awareness, and Expression Interview for Primary Care Patients With Medically Unexplained Symptoms: A Randomized Controlled Trial HEALTH PSYCHOLOGY Ziadni, M. S., Carty, J. N., Doherty, H. K., Porcerelli, J. H., Rapport, L. J., Schubiner, H., Lumley, M. A. 2018; 37 (3): 282–90

    Abstract

    Lifetime trauma, relationship adversities, and emotional conflicts are elevated in primary care patients with medically unexplained symptoms (MUS), and these risk factors likely trigger or exacerbate symptoms. Helping patients disclose stressors, increase awareness and expression of inhibited emotions, and link emotions to physical symptoms may improve health. We developed an emotional awareness and expression interview that targets stressful life experiences and conflicts and then tested its effects on primary care patients with MUS.Patients (N = 75) with MUS were recruited at a family medicine clinic and randomized to an interview condition or treatment-as-usual (TAU) control condition. In a single 90-min interview in the clinic, the interviewer elicited disclosure of the patient's stressors, linked them to the patient's symptom history, and encouraged emotional awareness and expression about unresolved relationship trauma or conflict. At baseline and 6-week follow-up, patients completed self-report measures of their physical and psychological health.Analyses of covariance, controlling for baseline symptoms, compared patients in the interview condition with TAU at 6-week follow-up. Compared with TAU, the interview led to significantly lower pain severity, pain interference, sleep problems, and global psychological symptoms.This study provides preliminary evidence for the value of integrating a disclosure and emotional awareness and expression interview into the primary care setting for patients with MUS.

  • Perceived injustice in chronic pain: an examination through the lens of predictive processing. Pain management Bissell, D. A., Ziadni, M. S., Sturgeon, J. A. 2018; 8 (2): 129–38

    Abstract

    Chronic pain conditions have been shown to be exacerbated by psychological factors, and a better understanding of these factors can inform clinical practice and improve the efficacy of interventions. The current paper investigates perceived injustice, a novel psychosocial construct, within a framework influenced by the tenets of predictive processing. The proposed conceptual model derived from tenets of predictive processing yields a single hierarchical self-reconfiguring system driven by prediction, which accounts for a wide range of human experiences such as perception, behavior, learning and emotion. This conceptualization can inform the development and implementation of more targeted therapeutic interventions for chronic pain.

  • Pain catastrophizing, perceived injustice, and pain intensity impair life satisfaction through differential patterns of physical and psychological disruption. Scandinavian journal of pain Sturgeon, J. A., Ziadni, M. S., Trost, Z., Darnall, B. D., Mackey, S. C. 2017; 17: 390-396

    Abstract

    Previous research has highlighted the importance of cognitive appraisal processes in determining the nature and effectiveness of coping with chronic pain.

    Abstract

    Previous research has highlighted the importance of cognitive appraisal processes in determining the nature and effectiveness of coping with chronic pain. Two of the key variables implicated in appraisal of pain are catastrophizing and perceived injustice, which exacerbate the severity of pain-related distress and increase the risk of long-term disability through maladaptive behavioural responses. However, to date, the influences of these phenomena have not been examined concurrently, nor have they been related specifically to quality of life measures, such as life satisfaction.Using data from an online survey of 330 individuals with chronic pain, structural path modelling techniques were used to examine the independent effects of pain catastrophizing, perceived injustice, and average pain intensity on life satisfaction. Two potential mediators of these relationships were examined: depressive symptoms and pain-related interference.Results indicated that depressive symptoms fully mediated the relationship between pain catastrophizing and life satisfaction, and pain interference fully mediated the relationship between pain intensity and life satisfaction. Both depressive symptoms and pain interference were found to significantly mediate the relationship between perceived injustice and life satisfaction, but perceived injustice continued to demonstrate a significant and negative relationship with life satisfaction, above and beyond the other study variables.The current findings highlight the distinct affective and behavioural mediators of pain and maladaptive cognitive appraisal processes in chronic pain, and highlight their importance in both perceptions of pain-related interference and longer-term quality of life.
