Factors associated with oncology patients' involvement in shared decision making during chemotherapy.
Oncology patients are increasingly encouraged to play an active role in treatment decision making. While previous studies have evaluated relationships between demographic characteristics and decision-making roles, less is known about the association of symptoms and psychological adjustment characteristics (eg, coping styles and personality traits) and decision-making roles.As part of a larger study of symptom clusters, patients (n = 765) receiving chemotherapy for breast, gastrointestinal, gynecological, or lung cancer provided information on demographic, clinical, symptom, and psychological adjustment characteristics. Patient-reported treatment decision-making roles (ie, preferred role and role actually played) were assessed using the Control Preferences Scale. Differences among patients, who were classified as passive, collaborative, or active, were evaluated using χ(2) analyses and analyses of variance.Over half (56.3%) of the patients reported that they both preferred and actually played a collaborative role. Among those patients with concordant roles, those who were older, those with less education and lower income, and those who were less resilient were more likely to prefer a passive role. Several psychological adjustment characteristics were associated with decision-making role, including coping style, personality, and fatalism.Oncology patients' preferences for involvement in treatment decision making are associated with demographic characteristics as well as with symptoms and psychological adjustment characteristics, such as coping style and personality. These results reaffirm the complexities of predicting patients' preferences for involvement in decision making. Further study is needed to determine if role or coping style may be influenced by interventions designed to teach adaptive coping skills.

Predictors of Altered Upper Extremity Function During the First Year After Breast Cancer Treatment.
American journal of physical medicine & rehabilitation
2016; 95 (9): 639-655
The purpose of this study was to evaluate trajectories of and predictors for changes in upper extremity (UE) function in women (n = 396) during the first year after breast cancer treatment.Prospective, longitudinal assessments of shoulder range of motion (ROM), grip strength, and perceived interference of function were performed before and for 1 year after surgery. Demographic, clinical, and treatment characteristics were evaluated as predictors of postoperative function.Women had a mean (SD) age of 54.9 (11.6) years, and 64% were white. Small but statistically significant reductions in shoulder ROM were found on the affected side over 12 months (P < 0.001). Predictors of interindividual differences in ROM at the 1-month assessment were ethnicity, neoadjuvant chemotherapy, type of surgery, axillary lymph node dissection, and preoperative ROM. Predictors of interindividual differences in changes over time in postoperative ROM were living alone, type of surgery, axillary lymph node dissection, and adjuvant chemotherapy. Declines in mean grip strength from before through 1 month after surgery were small and not clinically meaningful. Women with greater preoperative breast pain interference scores had higher postoperative interference scores at all postoperative assessments.Some of the modifiable risk factors identified in this study can be targeted for intervention to improve UE function in these women.

Differences in demographic, clinical, and symptom characteristics and quality of life outcomes among oncology patients with different types of pain.
2016; 157 (4): 892-900
The purposes of this study, in oncology outpatients receiving chemotherapy (n = 926), were to: describe the occurrence of different types of pain (ie, no pain, only noncancer pain [NCP], only cancer pain [CP], or both CP and NCP) and evaluate for differences in demographic, clinical, and symptom characteristics, and quality of life (QOL) among the 4 groups. Patients completed self-report questionnaires on demographic and symptom characteristics and QOL. Patients who had pain were asked to indicate if it was or was not related to their cancer or its treatment. Medical records were reviewed for information on cancer and its treatments. In this study, 72.5% of the patients reported pain. Of the 671 who reported pain, 21.5% reported only NCP, 37.0% only CP, and 41.5% both CP and NCP. Across the 3 pain groups, worst pain scores were in the moderate to severe range. Compared with the no pain group, patients with both CP and NCP were significantly younger, more likely to be female, have a higher level of comorbidity, and a poorer functional status. In addition, these patients reported: higher levels of depression, anxiety, fatigue, and sleep disturbance; lower levels of energy and attentional function; and poorer QOL. Patients with only NCP were significantly older than the other 3 groups. The most common comorbidities in the NCP group were back pain, hypertension, osteoarthritis, and depression. Unrelieved CP and NCP continue to be significant problems. Oncology outpatients need to be assessed for both CP and NCP conditions.

Associations between catecholaminergic, GABAergic, and serotonergic genes and self-reported attentional function in oncology patients and their family caregivers
EUROPEAN JOURNAL OF ONCOLOGY NURSING
2015; 19 (3): 251-259
Evaluate for associations between variations in genes involved in catecholaminergic, gamma-aminobutyric acid (GABA)-ergic, and serotonergic mechanisms of neurotransmission and attentional function latent classes.This descriptive, longitudinal study was conducted at two radiation therapy departments. The sample included three latent classes of individuals with distinct trajectories of self-reported attentional function during radiation therapy, who were previously identified using growth mixture modeling among 167 oncology patients and 85 of their family caregivers. Multivariable models were used to evaluate for genotypic associations of neurotransmission genes with attentional function latent class membership, after controlling for covariates.Variations in catecholaminergic (i.e., ADRA1D rs4815675, SLC6A3 rs37022), GABAergic (i.e., SLC6A1 rs2697138), and serotonergic (i.e., HTR2A rs2296972, rs9534496) neurotransmission genes were significant predictors of latent class membership in multivariable models.Findings suggest that variations in genes that encode for three distinct but related neurotransmission systems are involved in alterations in attentional function. Knowledge of both phenotypic and genetic markers associated with alterations in attentional function can be used by clinicians to identify patients and family caregivers who are at higher risk for this symptom. Increased understanding of the genetic markers associated with alterations in attentional function may provide insights into the underlying mechanisms for this significant clinical problem.

Cytokine gene variations associated with trait and state anxiety in oncology patients and their family caregivers
SUPPORTIVE CARE IN CANCER
2015; 23 (4): 953-965
Anxiety is common among cancer patients and their family caregivers (FCs) and is associated with poorer outcomes. Recently, associations between inflammation and anxiety were identified. However, the relationship between variations in cytokine genes and anxiety warrants investigation. Therefore, phenotypic and genotypic characteristics associated with trait and state anxiety were evaluated in a sample of 167 oncology patients with breast, prostate, lung, or brain cancer and 85 of their FCs.Using multiple regression analyses, the associations between participants' demographic and clinical characteristics as well as variations in cytokine genes and trait and state anxiety were evaluated.In the bivariate analyses, a number of phenotypic characteristics were associated with both trait and state anxiety (e.g., age, functional status). However, some associations were specific only to trait anxiety (e.g., number of comorbid conditions) or state anxiety (e.g., participation with a FC). Variations in three cytokine genes (i.e., interleukin (IL) 1 beta, IL1 receptor 2 (IL1R2), nuclear factor kappa beta 2 (NFKB2)) were associated with trait anxiety, and variations in two genes (i.e., IL1R2, tumor necrosis factor alpha (TNFA)) were associated with state anxiety.These findings suggest that both trait and state anxiety need to be assessed in oncology patients and their FCs. Furthermore, variations in cytokine genes may contribute to higher levels of anxiety in oncology patients and their FCs.

A Systematic Review and Meta-analysis of Psychotherapy for Late-Life Depression
AMERICAN JOURNAL OF GERIATRIC PSYCHIATRY
2015; 23 (3): 261-273
To determine the efficacy of psychotherapy in late-life depression and to determine the effect of the type of control group on the magnitude of psychotherapy effects.A systematic review and meta-analysis of randomized controlled psychotherapy trials for late-life depression.Outpatient clinics or in subjects' home.Subjects aged 55 years or older with acute-phase depressive disorder.Change in depressive symptoms was measured with validated scales. Standardized mean differences (SMD) were calculated for each therapy-control contrast, as meta-analytic summaries for contrasts using a similar control, and for all contrasts combined.The search identified 27 trials with 37 therapy-control contrasts and 2,245 subjects. Trials utilized five types of control groups (waitlist, treatment-as-usual, attention, supportive therapy, placebo). In the combined contrasts, psychotherapy was effective (SMD: 0.73; 95% confidence interval [CI]: 0.51, 0.95; z=6.42, p<0.00001). The SMD varied widely (from 0.05 to 1.36) and significantly (χ2=35.67, df=4, p<0.00001) between subgroups by type of control. In five trials that compared psychotherapy with supportive therapy, the SMD was 0.39 (95% CI: 0.16, 0.61; z=3.37, p<0.0007; I2=0%). The SMD was 0.11 within the waitlist controls and 1.10 within the supportive therapy subgroup.Psychotherapy is effective for late-life depression, but the magnitude of the effect varies widely with the type of control group. Supportive therapy appears to best control for the nonspecific elements of psychotherapy and is associated with considerable change itself, but few trials have utilized it as a control.

Predictors of Initial Levels and Trajectories of Anxiety in Women Before and for 6 Months After Breast Cancer Surgery
2014; 37 (6): 406-417
The diagnosis of breast cancer, in combination with the anticipation of surgery, evokes fear, uncertainty, and anxiety in most women.Study purposes were to examine in patients who underwent breast cancer surgery how ratings of state anxiety changed from the time of the preoperative assessment to 6 months after surgery and to investigate whether specific demographic, clinical, symptom, and psychosocial adjustment characteristics predicted the preoperative levels of state anxiety and/or characteristics of the trajectories of state anxiety.Patients (n = 396) were enrolled preoperatively and completed the Spielberger State Anxiety inventory monthly for 6 months. Using hierarchical linear modeling, demographic, clinical, symptom, and psychosocial adjustment characteristics were evaluated as predictors of initial levels and trajectories of state anxiety.Patients experienced moderate levels of anxiety before surgery. Higher levels of depressive symptoms and uncertainty about the future, as well as lower levels of life satisfaction, less sense of control, and greater difficulty coping, predicted higher preoperative levels of state anxiety. Higher preoperative state anxiety, poorer physical health, decreased sense of control, and more feelings of isolation predicted higher state anxiety scores over time.Moderate levels of anxiety persist in women for 6 months after breast cancer surgery.Clinicians need to implement systematic assessments of anxiety to identify high-risk women who warrant more targeted interventions. In addition, ongoing follow-up is needed to prevent adverse postoperative outcomes and to support women to return to their preoperative levels of function.

Trajectories of Depressive Symptoms in Women Prior to and for Six Months After Breast Cancer Surgery.
Journal of applied biobehavioral research
2014; 19 (2): 79-105
Depressive symptoms are common in women with breast cancer. This study evaluated how ratings of depressive symptoms changed from the time of the preoperative assessment to 6 months after surgery and investigated whether specific demographic, clinical, and symptom characteristics predicted preoperative levels of and/or characteristics of the trajectories of depressive symptoms. Characteristics that predicted higher preoperative levels of depressive symptoms included being married/partnered; receipt of adjuvant chemotherapy; more fear of metastasis; higher levels of trait anxiety, state anxiety, sleep disturbance, problems with changes in appetite; more hours per day in pain; and lower levels of attentional function. Future studies need to evaluate associations between anxiety, fears of recurrence, and uncertainty, as well as personality characteristics and depressive symptoms.

Preliminary Evidence of an Association Between an Interleukin 6 Promoter Polymorphism and Self-Reported Attentional Function in Oncology Patients and Their Family Caregivers
BIOLOGICAL RESEARCH FOR NURSING
2014; 16 (2): 152-159
Subgroups of individuals may be at greater risk of cytokine-induced changes in attentional function. The purposes of this study were to identify subgroups of individuals with distinct trajectories of attentional function and evaluate for phenotypic and genotypic (i.e., cytokine gene polymorphisms) differences among these subgroups. Self-reported attentional function was evaluated in 252 participants (167 oncology patients and 85 family caregivers) using the Attentional Function Index before radiation therapy and at six additional assessments over 6 months. Three latent classes of attentional function were identified using growth mixture modeling: moderate (36.5%), moderate-to-high (48.0%), and high (15.5%) attentional function. Participants in the moderate class were significantly younger, with more comorbidities and lower functional status, than those in the other two classes. However, only functional status remained significant in multivariable models. Included in the genetic association analyses were 92 single nucleotide polymorphisms (SNPs) among 15 candidate genes. Additive, dominant, and recessive genetic models were assessed for each SNP. Controlling for functional status, only Interleukin 6 (IL6) rs1800795 remained a significant genotypic predictor of class membership in multivariable models. Each additional copy of the rare "G" allele was associated with a 4-fold increase in the odds of belonging to the lower attentional function class (95% confidence interval: [1.78, 8.92]; p = .001). Findings provide preliminary evidence of subgroups of individuals with distinct trajectories of attentional function and of a genetic association with an IL6 promoter polymorphism.

Association between an interleukin 1 receptor, type I promoter polymorphism and self-reported attentional function in women with breast cancer
2014; 65 (2): 192-201
Subgroups of patients with breast cancer may be at greater risk for cytokine-induced changes in cognitive function after diagnosis and during treatment. The purposes of this study were to identify subgroups of patients with distinct trajectories of attentional function and evaluate for phenotypic and genotypic (i.e., cytokine gene polymorphisms) predictors of subgroup membership. Self-reported attentional function was evaluated in 397 patients with breast cancer using the Attentional Function Index before surgery and for six months after surgery (i.e., seven time points). Using growth mixture modeling, three attentional function latent classes were identified: High (41.6%), Moderate (25.4%), and Low-moderate (33.0%). Patients in the Low-moderate class were significantly younger than those in the High class, with more comorbidities and lower functional status than the other two classes. No differences were found among the classes in years of education, race/ethnicity, or other clinical characteristics. DNA was recovered from 302 patients' samples. Eighty-two single nucleotide polymorphisms among 15 candidate genes were included in the genetic association analyses. After controlling for age, comorbidities, functional status, and population stratification due to race/ethnicity, IL1R1 rs949963 remained a significant genotypic predictor of class membership in the multivariable model. Carrying the rare "A" allele (i.e., GA+AA) was associated with a twofold increase in the odds of belonging to a lower attentional function class (OR: 1.98; 95% CI: 1.18, 3.30; p=.009). Findings provide evidence of subgroups of women with breast cancer who report distinct trajectories of attentional function and of a genetic association between subgroup membership and an IL1R1 promoter polymorphism.

Assessing Professionalism and Ethics Knowledge and Skills: Preferences of Psychiatry Residents
2013; 37 (6): 392-397
Professionalism is one of the fundamental expectations and a core competency in residency education. Although programs use a variety of evaluative methods, little is known about residents' views of and preferences regarding various methods of assessment.The authors surveyed residents at seven psychiatry residency programs in the United States regarding their attitudes on professionalism, ethics preparation, and evaluation in psychiatry residency training. This report describes their views on methods of assessing professionalism.Residents strongly agreed that clinical supervision is an appropriate assessment method. Moreover, they rated clinical supervision more highly than oral examinations, short-answer questions, essays, and standardized patient interactions. Residents also strongly favored direct faculty observation of residents' interactions with actual patients and clinical team members.This study suggests that both direct faculty supervision and other clinically-based assessments are methods accepted by psychiatry residents. Future research on the validity and effectiveness of these modes of assessment is needed.

"Thinking About It for Somebody Else": Alzheimer's Disease Research and Proxy Decision Makers' Translation of Ethical Principles Into Practice
AMERICAN JOURNAL OF GERIATRIC PSYCHIATRY
2013; 21 (4): 337-345
Ethical guidelines suggest that, when enrolling patients with dementia in research, alterative decision makers (proxies) should base their decision on a "substituted judgment" of how the patient would have decided. If unable to make a substituted judgment, proxies are asked to decide on the basis of the patient's best interests. This mixed-methods study is the first to examine explicitly whether and to what degree proxies differentiate between these two approaches and what considerations influence their mode of decision making.Interview study regarding enrollment of relative in hypothetical clinical trial of an investigational drug for Alzheimer disease. Participants were randomized to respond to questions about one of four hypothetical clinical trials that differed by levels of described risk and potential benefit.Proxy decision makers (N = 40).Open-ended and rating-scaled items.Half of the proxies agreed with both of two rating-scaled items asking about different approaches to decision making-that is, agreeing that they would decide on the basis of how their relative would have decided and agreeing that they would decide on the basis of what they believed was in their relative's best interests. Narrative responses elaborated on themes within the following three major domains: Substituted judgment, best interests, and weighing substituted judgment and best interests. Substituted judgment was framed as honoring the patient's wishes and values. Best interests was described as a perceived duty to maintain quality of life and avoid burdens or risks. Weighing the two standards emerged as a challenging yet important, way of honoring wishes while maintaining quality of life. An unexpected theme was the attempt by alternative decision makers to discern their loved one's current versus premorbid research preferences.Tensions exist between abstract ethical principles regarding decision-making "standards" and their translation into research decisions.

Alternative Decision-Makers' Perspectives on Assent and Dissent for Dementia Research
AMERICAN JOURNAL OF GERIATRIC PSYCHIATRY
2013; 21 (4): 346-354
Investigators generally address the ethical dilemma of patients' decisional impairment in Alzheimer disease (AD) research by obtaining consent from alternative or surrogate decision makers ("proxies") as well as assent from patients. How these proxies conceptualize patient assent, or lack of objection, to participate may influence decisions made of the patients' behalf, but has been little studied. This report examines statements of proxies relevant to how they conceptualized assent and dissent to research.Surveys and in-depth interviews of proxies presented with hypothetical scenario related to enrolling relatives with AD in a clinical trial of an investigational drug for AD.Proxies (n = 25) for people with AD.Open-ended and rating-scaled items assessing perspectives on enrollment in research, influences on decision-making, and willingness to override a relative's preferences regarding research participation. Statements with relevance to assent or dissent were coded.Proxies described looking for consistent behavioral or verbal indications of assent versus objection when trying to determine patients' preferences. However, proxies sometimes expressed willingness to override patients' desires in favor of patients' presumed best interests. The amnestic nature of the disorder led some proxies to justify overriding temporary dissent or discomfort in the interest of promoting patients' values. Patients' dependence on their caregivers for decision-making, and caregivers' awareness of their ability to persuade their relatives, also emerged in descriptions of the decision-making process.Proxies' statements regarding a hypothetical research enrollment decision revealed several themes with implications for the concepts of assent and dissent. Proxies may persuade or influence patients to promote the patient's best interests or values. Further work, particularly examining actual decision-making, is warranted to determine how best to operationalize the concepts of assent and dissent in the context of research involving decisionally impaired adults.

Amyloid imaging, risk disclosure and Alzheimer's disease: ethical and practical issues.
Neurodegenerative disease management
2013; 3 (3): 219-229
PET ligands that bind with high specificity to amyloid plaques represent a major breakthrough in Alzheimer's disease (AD) research. Amyloid neuroimaging is now approved by the US FDA to aid in the diagnosis of AD, and is being used to identify amyloid-positive but asymptomatic individuals for secondary AD prevention trials. The use of amyloid neuroimaging in preclinical populations raises important ethical and practical challenges, including determining appropriate uses of this technology, evaluating the potential benefits and harms of disclosing results, and communicating effectively about testing with patients and family members. Emerging policy issues also require consideration (e.g., legal safeguards for biomarker-positive individuals). Further research is needed to inform effective and ethical implementation and regulation of amyloid imaging.

Evidence of Associations between Cytokine Genes and Subjective Reports of Sleep Disturbance in Oncology Patients and Their Family Caregivers
2012; 7 (7)
The purposes of this study were to identify distinct latent classes of individuals based on subjective reports of sleep disturbance; to examine differences in demographic, clinical, and symptom characteristics between the latent classes; and to evaluate for variations in pro- and anti-inflammatory cytokine genes between the latent classes. Among 167 oncology outpatients with breast, prostate, lung, or brain cancer and 85 of their FCs, growth mixture modeling (GMM) was used to identify latent classes of individuals based on General Sleep Disturbance Scale (GSDS) obtained prior to, during, and for four months following completion of radiation therapy. Single nucleotide polymorphisms (SNPs) and haplotypes in candidate cytokine genes were interrogated for differences between the two latent classes. Multiple logistic regression was used to assess the effect of phenotypic and genotypic characteristics on GSDS group membership. Two latent classes were identified: lower sleep disturbance (88.5%) and higher sleep disturbance (11.5%). Participants who were younger and had a lower Karnofsky Performance status score were more likely to be in the higher sleep disturbance class. Variation in two cytokine genes (i.e., IL6, NFKB) predicted latent class membership. Evidence was found for latent classes with distinct sleep disturbance trajectories. Unique genetic markers in cytokine genes may partially explain the interindividual heterogeneity characterizing these trajectories.

EVALUATION OF THE CONTENT AND PROCESS OF INFORMED CONSENT DISCUSSIONS FOR NEONATAL RESEARCH
JOURNAL OF EMPIRICAL RESEARCH ON HUMAN RESEARCH ETHICS
2012; 7 (3): 78-83
Studies of informed consent for neonatal research suggest that there are gaps in parental understanding of key aspects of research. Few studies have examined parental understanding and investigator disclosure simultaneously. This pilot study evaluated the content and processes of 21 audio-recorded consent discussions with parents of eligible newborns, as well as parents' self-reported comprehension of research elements following these discussions. Gaps in both investigator disclosure and parental understanding were found. Nevertheless, parents reported comprehension of a greater number of research elements than were actually disclosed by investigators. Our preliminary results indicate the feasibility and potential utility of jointly examining parental understanding and investigator behavior to characterize consent for neonatal research. Directions for future research are suggested.

Participants' Perceptions of Deep Brain Stimulation Research for Treatment-Resistant Depression: Risks, Benefits, and Therapeutic Misconception.
AJOB primary research
2011; 2 (4): 33-41
Deep brain stimulation (DBS) for treatment-resistant depression (TRD) is the focus of great interest and numerous studies. Given the state of this research, the risks of DBS, the uncertainty of direct benefits, and the potential for therapeutic misconception (TM), examination of research participants' perspectives is critical to addressing concerns about the adequacy of consent among people with TRD.Among 31 participants considering DBS studies at two sites, self-report questionnaires were used to examine three dimensions of TM (eight true/false items). Additional Likert-scale items assessed perceptions of risks, potential benefits, and altruistic motivations.Participants correctly identified the surgery itself as the riskiest study procedure, although only four participants rated the surgery as "high risk." Most participants rated the entire DBS study as "moderate" or lower risk. Participants rated the likelihood of others benefiting in the future more strongly than they did the likelihood of personal benefit. Participants held positive attitudes toward research, and were moderately altruistic. Nearly two-thirds of the 31 participants (64.5%) answered at least one of the true/false TM items incorrectly.Individuals considering DBS studies for TRD demonstrated reasonable perceptions of risks and benefits, distinguished among procedural risks, and expressed hopes for personal benefit as well as altruism. Findings related to TM were mixed: Participants understood the experimental stage of DBS for depression and endorsed the possibility of no personal benefit, yet there was some evidence for TM. Although these findings are reassuring, investigators must nevertheless remain vigilant about identifying and addressing potential misconceptions.

Sleep-Wake Circadian Activity Rhythm Parameters and Fatigue in Oncology Patients Before the Initiation of Radiation Therapy
2011; 34 (4): 255-268
Little is known about the relationships between sleep parameters and fatigue in patients at the initiation of radiation therapy (RT).The objectives of this study were to describe values for nocturnal sleep/rest, daytime wake/activity, and circadian activity rhythm parameters measured using actigraphy and to evaluate the relationships between these objective parameters and subjective ratings of sleep disturbance and fatigue severity, in a sample of patients at the initiation of RT.Patients (n = 185) with breast, prostate, lung, or brain cancer completed self-report measures for sleep disturbance (ie, Pittsburgh Sleep Quality Index, General Sleep Disturbance Scale) and fatigue (Lee Fatigue Scale) and wore wrist actigraphs for a total of 48 hours prior to beginning RT. Actigraphy data were analyzed using the Cole-Kripke algorithm. Spearman rank correlations were calculated between variables.Approximately 30% to 50% of patients experienced sleep disturbance, depending on whether clinically significant cutoffs for the subjective or objective measures were used to calculate occurrence rates. In addition, these patients reported moderate levels of fatigue. Only a limited number of significant correlations were found between the subjective and objective measures of sleep disturbance. Significant positive correlations were found between the subjective, but not the objective measures of sleep disturbance and fatigue.A significant percentage of oncology patients experience significant disturbances in sleep-wake circadian activity rhythms at the initiation of RT. The disturbances occur in both sleep initiation and sleep maintenance.Patients need to be assessed at the initiation of RT for sleep disturbance, so appropriate treatment is initiated.

Results of a Multisite Survey of US Psychiatry Residents on Education in Professionalism and Ethics
2011; 35 (3): 175-183
The authors assess the perspectives of psychiatry residents about the goals of receiving education in professionalism and ethics, how topics should be taught, and on what ethical principles the curriculum should be based.A written survey was sent to psychiatry residents (N=249) at seven U.S. residency programs in Spring 2005. The survey was based on an instrument originally developed at the University of New Mexico, consisting of 149 questions in 10 content domains, with 6 questions regarding ethics experiences during training and 5 demographic questions.A total of 151 psychiatry residents (61%) returned usable responses to our survey. Residents reported receiving a moderate amount of ethics training during medical school (mean: 5.20; scale: 1: None to 9: Very Much) and some ethics training during residency (mean: 4.60). Residents endorsed moderate to moderately-strong agreement with all 11 goals of medical education in professionalism and ethics (means: 5.29 to 7.49; scale: 1: Strongly Disagree to 9: Strongly Agree). Respondents were more likely to endorse the value of clinically- and expert-oriented learning methods over web-based educational approaches.U.S. psychiatry residents endorse a range of goals for education in professionalism and ethics. At the same time, they prefer that these topics be taught in clinically relevant ways and through expert instruction. The value of web-based approaches warrants further investigation.

Psychiatric Residents' Needs for Education About Informed Consent, Principles of Ethics and Professionalism, and Caring for Vulnerable Populations: Results of a Multisite Survey
2011; 35 (3): 184-190
The authors examined psychiatric residents' perceived needs for education in informed consent, principles of ethics and professionalism, and treating vulnerable populations.A written survey was distributed to psychiatric residents (N=249) at seven U.S. residency programs in 2005. The survey contained 149 questions in 10 content domains, 6 questions regarding personal ethics experiences during training, and 5 demographic questions. Here, the authors report responses to items regarding informed consent, professional principles, and care of vulnerable populations.A total of 151 psychiatric residents responded to the survey (61% overall response rate). On a scale of 1: Much Less, to 5: Same, to 9: Much More Education Desired, psychiatric residents indicated that 9 topics relating to informed consent, 10 issues surrounding professional principles, and 25 topics relating to care of vulnerable populations should receive more educational attention than currently provided. No topics were rated as needing less education. Higher ratings of the need for additional educational attention were associated with more reported ethical conflicts encountered during training.Psychiatric residents at seven diverse U.S. training programs expressed the need for greater educational attention to issues around informed consent, ethical and professional principles, and treating vulnerable populations. These findings reflect the ongoing need for educators to devote curricular attention to these areas so that trainees can incorporate such knowledge effectively into their daily clinical practice in an always-complex, highly fragmented medical care environment.

Differences in Sleep Disturbance Parameters Between Oncology Outpatients and Their Family Caregivers
JOURNAL OF CLINICAL ONCOLOGY
2011; 29 (8): 1001-1006
This study compared the occurrence rates for and severity ratings of sleep disturbance in patient-family caregiver (FC) dyads.In total, 102 dyads were recruited from two radiation therapy (RT) departments. Patients and their FCs completed the Pittsburgh Sleep Quality Index (PSQI) and the General Sleep Disturbance Scale (GSDS) and wore wrist actigraphs to obtain subjective and objective measures of the occurrence and severity of sleep disturbance at the initiation of RT. Match paired t tests were used to evaluate for dyadic differences.No differences were found in the occurrence of clinically significant levels of sleep disturbance between patients and their FCs that ranged between 40% and 50% using subjective and objective measures. Few differences were found in the severity of any of the sleep-wake parameters between patients and FCs using both the subjective and objective measures of sleep disturbance.The findings from this study suggest that patients with cancer and their FCs experience similar levels of sleep disturbance and that both groups could benefit from interventions that aim to promote restful sleep. In addition to routine and systematic assessment of sleep disturbance by oncology clinicians, interventions are needed that take into account the specific needs of the patient and the FC as well as the potential for partners' sleep patterns to influence one another.

Psychiatric residents' interest in psychotherapy and training stage: a multi-site survey.
American journal of psychotherapy
2011; 65 (1): 47-59
Most psychiatric residents enter training intent on learning both psychopharmacologic and psychotherapeutic interventions. After graduation, however, many emphasize pharmacotherapy over psychotherapy.A multisite survey of psychiatry residents queried psychotherapy interests, attitudes, and practice intentions. Factors associated with self-reported decreased interest in psychotherapy since beginning residency were examined.Although 11.8% of the entire sample (n = 229 PGY1-PGY4 residents) reported decreased interest in psychotherapy during training, among PGY4s the corresponding figure was 16.4%. Positive attitudes towards psychotherapy, and self-perceived competence in cognitive-behavioral and psychodynamic psychotherapy were most highly correlated with maintained interest in psychotherapy. Dissatisfaction with the quality of psychotherapy faculty and curriculum, and viewing departmental leadership as unsupportive of psychotherapy training were correlated with decreased interest during training.Maintaining residents' interest in psychotherapy requires improvements in curriculum, teaching, and supervision throughout training. Our data underscore the crucial role that departmental leadership must play in supporting trainees' goals of becoming comprehensively trained psychiatrists.

Ethical Issues in Deep Brain Stimulation Research for Treatment-Resistant Depression: Focus on Risk and Consent.
2011; 2 (1): 29-36
Deep brain stimulation (DBS) is currently in pivotal trials as an intervention for treatment-resistant depression (TRD). Although offering hope for TRD, DBS also provokes ethical concerns-particularly about decision-making capacity of people with depression-among bioethicists, investigators, institutional review boards, and the public. Here, we examine this critical issue of informed consent for DBS research using available evidence regarding decision-making capacity and depression. Further, we explore the implications of the nature of TRD as well as that of the intervention (invasive brain surgery) for informed consent. Based on these analyses, we argue that additional safeguards specific to DBS research for TRD, beyond those that might be used in any higher risk study, are not supported by available empirical evidence. We nevertheless underscore the limited data on such invasive procedures in severely ill psychiatric patients and advocate a research agenda for the systematic study of ethical issues raised by these research endeavors.

Multimedia Consent for Research in People With Schizophrenia and Normal Subjects: a Randomized Controlled Trial
2009; 35 (4): 719-729
Limitations of printed, text-based, consent forms have long been documented and may be particularly problematic for persons at risk for impaired decision-making capacity, such as those with schizophrenia. We conducted a randomized controlled comparison of the effectiveness of a multimedia vs routine consent procedure (augmented with a 10-minute control video presentation) as a means of enhancing comprehension among 128 middle-aged and older persons with schizophrenia and 60 healthy comparison subjects. The primary outcome measure was manifest decisional capacity (understanding, appreciation, reasoning, and expression of choice) for participation in a (hypothetical) clinical drug trial, as measured with the MacArthur Competence Assessment Tool for Clinical Research (MacCAT-CR) and the University of California San Diego (UCSD) Brief Assessment for Capacity to Consent (UBACC). The MacCAT-CR and UBACC were administered by research assistants kept blind to consent condition. Additional assessments included standardized measures of psychopathology and cognitive functioning. Relative to patients in the routine consent condition, schizophrenia patients receiving multimedia consent had significantly better scores on the UBACC and on the MacCAT-CR understanding and expression of choice subscales and were significantly more likely to be categorized as being capable to consent than those in the routine consent condition (as categorized with several previously established criteria). Among the healthy subjects, there were few significant effects of consent condition. These findings suggest that multimedia consent procedures may be a valuable consent aid that should be considered for use when enrolling participants at risk for impaired decisional capacity, particularly for complex and/or high-risk research protocols.

Multimedia educational aids for improving consumer knowledge about illness management and treatment decisions: A review of randomized controlled trials
JOURNAL OF PSYCHIATRIC RESEARCH
2008; 42 (1): 1-21
Psychiatric practice is becoming increasingly more complex in terms of the available treatment options, use of new technologies for assessments, and a need for psychiatric patients and their caregivers to be familiar with general medical procedures. This trend will only intensify in the years to come. Routine methods of providing information relevant to clinical decision making about healthcare evaluations or management are often suboptimal. Relatively little research has been done on enhancing the capacity of psychiatric patients and the caregivers to make truly informed decisions about management. In this paper, we review studies that compared the effects of multimedia (video- or computer-based) educational aids with those of routine procedures to inform healthcare consumers about medical evaluations or management. Although most of these investigations were conducted in non-psychiatric patients, the results should be relevant for psychiatric practice of tomorrow. We searched MEDLINE, PsycINFO, and CINAHL bibliographic databases. Randomized controlled trials that used objective measures of knowledge or understanding of the information provided were selected. Studies were rated as positive if the multimedia educational aid resulted in a greater improvement in knowledge or understanding than the control condition. The quality of each study was also rated using a newly developed Scale for Assessing Scientific Quality of Investigations (SASQI). A total of 37 randomized controlled trials were identified. Nearly two-thirds of the studies (23/37) in diverse patient populations and for varied medical assessments and treatments reported that multimedia educational aids produced better understanding of information compared to routine methods. SASQI scores for the positive and negative studies were comparable, suggesting that lower quality was not related to positive findings. In conclusion, multimedia educational aids hold promise for improving the provision of complex medical information to patients and caregivers. It is likely that as psychiatric patients and their treating clinicians face increasingly complex choices regarding mental health treatment, multimedia decisional aids could become an effective supplement to the clinician patient interaction in near future.

A new brief instrument for assessing decisional capacity for clinical research
ARCHIVES OF GENERAL PSYCHIATRY
2007; 64 (8): 966-974
There is a critical need for practical measures for screening and documenting decisional capacity in people participating in different types of clinical research. However, there are few reliable and validated brief tools that could be used routinely to evaluate individuals' capacity to consent to a research protocol.To describe the development, testing, and proposed use of a new practical instrument to assess decision-making capacity: the University of California, San Diego Brief Assessment of Capacity to Consent (UBACC). The UBACC is intended to help investigators identify research participants who warrant more thorough decisional capacity assessment and/or remediation efforts prior to enrollment.We developed the UBACC as a 10-item scale that included questions focusing on understanding and appreciation of the information concerning a research protocol. It was developed and tested among middle-aged and older outpatients with schizophrenia and healthy comparison subjects participating in research on informed consent. In an investigation of reliability and validity, we studied 127 outpatients with schizophrenia or schizoaffective disorder and 30 healthy comparison subjects who received information about a simulated clinical drug trial. Internal consistency, interrater reliability, and concurrent (criterion) validity (including correlations with an established instrument as well as sensitivity and specificity relative to 2 potential "gold standard" criteria) were measured.Reliability and validity of the UBACC.The UBACC was found to have good internal consistency, interrater reliability, concurrent validity, high sensitivity, and acceptable specificity. It typically took less than 5 minutes to administer, was easy to use and reliably score, and could be used to identify subjects with questionable capacity to consent to the specific research project.The UBACC is a potentially useful instrument for screening large numbers of subjects to identify those needing more comprehensive decisional capacity assessment and/or remediation efforts.
