Replication and extension of dietary adherence as a predictor of suboptimal weight-loss outcomes in postbariatric patients.
Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery
BACKGROUND: Sarwer et al. found that poor dietary adherence at 6 months postoperatively predicted lower weight loss.OBJECTIVES: To replicate and extend these findings.SETTING: University bariatric clinic.METHODS: Fifty-four adults (72% female; age 51.1 ± 11.3 yr; mean body mass index [BMI] = 43.8 ± 7.4 kg/m2; 53.7% = Roux-en-Y gastric bypass, 42.6% = laparoscopic sleeve gastrectomy, and 3.7% = gastric banding) were identified as low or high dietary adherers following the method of Sarwer et al. Patients self-reported dietary adherence with a 9-point Likert scale. Splitting the group at the median, low adherers scored <7 and high dietary adherers ≥7. BMI, percentage excess weight loss (%EWL), and percentage total weight loss (%TWL) were prospectively assessed at 12, 24, and 36 months. Two-tailed independent t tests and Cohen's d effect sizes were used to compare between-group outcomes.RESULTS: BMI did not differ between low (n = 24) and high (n = 30) dietary adherers at 6 months after surgery. At 12 months, the BMI of low (n = 17) adheres was significantly higher (34.1 ± 4.61 versus 30.3 ± 3.90 kg/m2, P = .006, d = 0.90) than that of high (n = 25) adherers, with significantly less %EWL (49.0 ± 24% versus 70.7 ± 21.5%; P = .004; d = 0.95) and %TWL (20.7 ± 11.5% versus 28.9 ± 10.5, P = .02, d = 0.74). At 24 months, BMI remained significantly higher for low (n = 12) versus high (n = 10) adherers (33.7 ± 4.77 versus 29.7 ± 3.82 kg/m2, P = .045, d = 0.92), but %EWL and %TWL were not significantly different, despite large effect sizes. At 36 months, moderate effects supported continued higher BMIs and lower %EWL and %TWL for low (n = 5) versus high (n = 8) adherers. Attrition from follow-up was 22.2% (12 mo), 59.3% (24 mo), and 75.9% (36 mo). Post hoc analyses revealed no impact of baseline characteristics on low follow-up rates except younger age (at 1 yr).CONCLUSIONS: Findings that 6-month postoperative dietary adherence predicts 12-month BMI, %EWL, and %TWL were replicated. Medium to large effects suggest findings extend to 24 and 36 months, with low follow-up rates likely affecting statistical significance.

Correlates of Dietary Adherence and Maladaptive Eating Patterns Following Roux-en-Y Bariatric Surgery
2018; 28 (4): 1130–35
Self-reported poor dietary adherence following bariatric surgery is associated with less successful weight loss outcomes. Poor dietary adherence is a global construct lacking specificity regarding its underlying, clinically targetable, maladaptive eating behaviors.Comprehensive online survey data were obtained from a sample of 274 adults who underwent Roux-en-Y surgery in the prior 1-12 years. Correlations between dietary adherence and six eating-related behaviors were calculated, with the frequency of each behavior reported on a 7-point scale. Linear regression modeling was applied.All six maladaptive eating behaviors were highly correlated with dietary adherence (Pearson's r > 0.5): grazing (r = - 0.565), mindless eating (r = - 0.572), loss of control eating (r = - 0.517), eating "more than is best" after dinner (r = - 0.518), eating foods off of one's plan (r = - 0.557), and "when I eat something off-plan, I feel like I have blown it and I give up and eat more" (r = - 0.574). The estimated regression coefficients in the linear model was statistically significant, [F(5, 261) = 60.006, p < 0.001] and accounted for approximately 54% of the variance of global dietary adherence (R 2 = 0.535, adjusted R 2 = 0.526).Six maladaptive eating behaviors accounted for a highly significant portion of post-Roux-en-Y patients' poor self- reported dietary adherence. Prospective studies are needed to investigate the relationship between targetable maladaptive eating behaviors and bariatric surgery outcomes.

Study protocol and rationale for a randomized double-blinded crossover trial of phentermine-topiramate ER versus placebo to treat binge eating disorder and bulimia nervosa.
Contemporary clinical trials
2018; 64: 173–78
Bulimia nervosa (BN) and binge eating disorder (BED) are associated with severe psychological and medical consequences. Current therapies are limited, leaving up to 50% of patients symptomatic despite treatment, underscoring the need for additional treatment options. Qsymia, an FDA-approved medication for obesity, combines phentermine and topiramate ER. Topiramate has demonstrated efficacy for both BED and BN, but limited tolerability. Phentermine is FDA-approved for weight loss. A rationale for combined phentermine/topiramate for BED and BN is improved tolerability and efficacy. While a prior case series exploring Qsymia for BED showed promise, randomized studies are needed to evaluate Qsymia's safety and efficacy when re-purposed in eating disorders. We present a study protocol for a Phase I/IIa single-center, prospective, double-blinded, randomized, crossover trial examining safety and preliminary efficacy of Qsymia for BED and BN.Adults with BED (n=15) or BN (n=15) are randomized 1:1 to receive 12weeks Qsymia (phentermine/topiramate ER, 3.75mg/23mg-15mg/92mg) or placebo, followed by 2-weeks washout and 12-weeks crossover, where those on Qsymia receive placebo and vice versa. Subsequently participants receive 8weeks follow-up off study medications. The primary outcome is the number of binge days/week measured by EDE. Secondary outcomes include average number of binge episodes, percentage abstinence from binge eating, and changes in weight/vitals, eating psychopathology, and mood.To our knowledge this is the first randomized, double-blind protocol investigating the safety and efficacy of phentermine/topiramate in BED and BN. We highlight the background and rationale for this study, including the advantages of a crossover design.Clinicaltrials.gov identifier NCT02553824 registered on 9/17/2015. https://clinicaltrials.gov/ct2/show/NCT02553824.

A Standardized Preoperative Group Intervention Is Feasible and Acceptable to Orthognathic Surgery Patients.
Journal of oral and maxillofacial surgery : official journal of the American Association of Oral and Maxillofacial Surgeons
PURPOSE: Nearly 10% of patients remain dissatisfied after orthognathic surgery, largely because of psychoeducational or psychosocial factors. The purpose of this study was to evaluate the feasibility and acceptability of a psychoeducationally based group intervention to improve preoperative preparation of orthognathic surgical patients and their caregivers.MATERIALS AND METHODS: The intervention consisted of 2 group sessions, with each session lasting 2hours. The sessions provided realistic expectations of the surgery, offered teaching strategies for coping with pre- and postoperative symptoms of psychopathology, and highlighted the importance of social support. Feasibility was based on attendance, homework completion, and data collection rates, and acceptability was based on post-treatment participant satisfaction scores on the Client Satisfaction Questionnaire-8 (CSQ-8) and credibility and expectancy scores on 2 subscales of the Credibility/Expectancy Questionnaire-Modified (CEQ-M).RESULTS: Twenty-six orthognathic surgical patients were recruited from an outpatient oral and maxillofacial surgery clinic to attend the group-based intervention. Seventy percent of patients who attended at least 1 session completed the 2 sessions, and 64% of those who attended the 2 sessions completed at least 1 homework assignment. The authors successfully collected 84% of the total measures given to patients and their caregivers. The mean satisfaction rating of the patients was 30.12 of 32 (CSQ-8; n=13; standard deviation [SD], 2.33), the mean credibility rating of the patients and their caregivers was 25.2 of 27 (CEQ-M; n=20; SD, 1.85), and the mean expectancy rating of the patients and their caregivers was 20.54 of 27 (CEQ-M; n=20; SD, 4.39).CONCLUSION: The psychoeducationally based group intervention was feasible and acceptable for participants and their caregivers. This article offers suggestions to further improve the feasibility and acceptability of the intervention, including optimizing standardization of data collection procedures, decreasing barriers to access, and increasing participant engagement.

Shifts in the Enjoyment of Healthy and Unhealthy Behaviors Affect Short- and Long-Term Postbariatric Weight Loss.
Bariatric surgical practice and patient care
2017; 12 (1): 35–42
Objective: To investigate whether bariatric patients experience changes in the enjoyment of health-promoting behaviors, and how those changes relate to weight loss success. Materials and Methods: Online lifestyle survey for bariatric patients ≥18 years old who had undergone gastric bypass or sleeve gastrectomy ≥1 year earlier. Changes in the enjoyment of eating behaviors and exercise were surveyed, and associations with weight loss success were analyzed. The role of obtaining external support since surgery was investigated. Results: Of 877 respondents, 475 were eligible (95% women, 53.3±9.0 years, body mass index 34.2±8.0kg/m2), of whom 21%, 36%, and 43% had had surgery 12-24, 24-60, and >60 months earlier, respectively. Postsurgery, patients enjoyed eating healthy foods more (63%), exercise more (46%), eating junk food less (66%), and overeating less (95%). Increased enjoyment of healthy foods and exercise were only associated with weight loss success among patients with surgery ≥24 months previously. While obtaining external support was associated with successful weight loss overall, external support correlated with enjoying healthy food and exercise more in patients who had had their surgery at least 60 months previously. Discussion: Learning to enjoy health-promoting behaviors after bariatric surgery may not coincide with improved weight loss outcomes before 2 years have passed.

Follow-up of selective eaters from childhood to adulthood.
2017; 26: 61-65
The aim of this study was to examine the prevalence and course of selective eating, the stability of its behavioral profile over time, and the presence of eating disorder psychopathology among selective eaters in a non-treatment seeking cohort of young adults followed longitudinally from birth to age 23.A prospective design tracking a subset of the original participants from the Stanford Infant Growth Study (n=216) who had been followed since birth. At age 11, 120 participants had completed all assessments. The current study included a subset of the original participants who, at age 11, had completed all assessments (n=120) and, at age 23, had current contact information available (n=62) and agreed to participate (n=61).Of the 61 young adults, 17 (28%) were identified as selective eaters at age 23. The selective eating-related behaviors reported during adulthood were similar to those endorsed during childhood. New onset selective eating cases were reported during adolescence or young adulthood by 35% of the selective eating sample. Participants who were selective eaters for >6years prior to age 11 remained selective at age 23. There was no evidence of increased eating disorder psychopathology, excessive thinness, or obesity in selective eaters compared with non-selective eaters.These results suggest that a proportion of selective eaters continue from childhood into adulthood with similar eating patterns; new onset selective eating occurs in adolescence or young adulthood; and selective and non-selective eaters at age 23 do not differ with regard to weight or eating psychopathology.

Does implicit emotion regulation in binge eating disorder matter?
2015; 18: 186-191
To examine if implicit emotion regulation (occurring outside of awareness) is related to binge eating disorder (BED) symptomatology and explicit emotion regulation (occurring within awareness), and can be altered via intervention.Implicit emotion regulation was assessed via the Emotion Conflict Task (ECT) among a group of adults with BED. Study 1 correlated BED symptomatology and explicit emotion regulation with ECT performance at baseline (BL) and after receiving BED treatment (PT). Study 2 generated effect sizes comparing ECT performance at BL and PT with healthy (non-eating disordered) controls (HC).Study 1 yielded significant correlations (p<.05) between both BED symptomatology and explicit emotion regulation with ECT performance. Study 2 found that compared to BL ECT performance, PT shifted (d=-.27), closer to HC. Preliminary results suggest a) BED symptomatology and explicit emotion regulation are associated with ECT performance, and b) PT ECT performance normalized after BED treatment.Implicit emotion regulation may be a BED treatment mechanism because psychotherapy, directly or indirectly, decreased sensitivity to implicit emotional conflict. Further understanding implicit emotion regulation may refine conceptualizations and effective BED treatments.

Student Bodies, an internet-based intervention, has successfully reduced weight/shape concerns and prevented eating disorders in a subset of college-age women at highest risk for an eating disorder. Student Bodies includes an online, guided discussion group; however, the clinical utility of this component is unclear. This study investigated whether the guided discussion group improves program efficacy in reducing weight/shape concerns in women at high risk for an eating disorder. Exploratory analyses examined whether baseline variables predicted who benefitted most. Women with high weight/shape concerns (N = 151) were randomized to Student Bodies with a guided discussion group (n = 74) or no discussion group (n = 77). Regression analyses showed weight/shape concerns were reduced significantly more among guided discussion group than no discussion group participants (p = 0.002; d = 0.52); guided discussion group participants had 67% lower odds of having high-risk weight/shape concerns post-intervention (p = 0.02). There were no differences in binge eating at post-intervention between the two groups, and no moderators emerged as significant. Results suggest the guided discussion group improves the efficacy of Student Bodies in reducing weight/shape concerns in college students at high risk for an eating disorder.

Change in emotion regulation during the course of treatment predicts binge abstinence in guided self-help dialectical behavior therapy for binge eating disorder.
Journal of eating disorders
2014; 2 (1): 35-?
Dialectical behavior therapy (DBT), which appears to be an effective treatment for binge eating disorder (BED), focuses on teaching emotion regulation skills. However, the role of improved emotion regulation in predicting treatment outcome in BED is uncertain.This secondary analysis explored whether change in self-reported emotion regulation (as measured by the Difficulties in Emotion Regulation Scale) during treatment was associated with abstinence from binge eating at post-treatment and 4-, 5-, and 6-month follow-up in individuals who received a guided self-help adaptation of DBT for BED. Participants were 60 community-based men and women with BED who received a self-help manual and six 20-minute support phone calls.Greater improvement in self-reported emotion regulation between pre- and post-treatment predicted abstinence from binge eating at post-treatment, 4-, 5-, and 6-month follow-up. However, some follow-up results were no longer significant when imputed data was excluded, suggesting that the effect of emotion regulation on binge abstinence may be strongest at 4-month follow-up but decline across a longer duration of follow-up.This study provides preliminary support for the theoretical role played by improved emotion regulation in achieving binge eating abstinence. If this finding is replicated with larger samples, further research should identify specific techniques to help more individuals to effectively regulate their emotions over a longer duration.

Do end of treatment assessments predict outcome at follow-up in eating disorders?
International journal of eating disorders
2013; 46 (8): 771-778
To examine the predictive value of end of treatment (EOT) outcomes for longer term recovery status.We used signal detection analysis to identify the best predictors of recovery based on outcome at EOT using five different eating disorder samples from randomized clinical treatment trials. We utilized a transdiagnostic definition of recovery that included normalization of weight and eating related psychopathology.Achieving a body weight of 95.2% of expected body weight by EOT is the best predictor of recovery for adolescents with anorexia nervosa (AN). For adults with AN, the most efficient predictor of weight recovery (BMI > 19) was weight gain to greater than 85.8% of ideal body weight. In addition, for adults with AN, the most efficient predictor of psychological recovery was achievement of an eating disorder examination (EDE) weight concerns score below 1.8. The best predictor of recovery for adults with Bulimia Nervosa (BN) was a frequency of compensatory behaviors less than two times a month. For adolescents with BN, abstinence from purging and reduction in the EDE restraint score of more than 3.4 from baseline to EOT were good predictors of recovery. For adults with binge eating disorder, reduction of the Global EDE score to within the normal range (<1.58) was the best predictor of recovery.The relationship between EOT response and recovery remains understudied. Utilizing a transdiagnostic definition of recovery, no uniform predictors were identified across all eating disorder diagnostic groups. © 2013 Wiley Periodicals, Inc.

A randomized wait-list controlled pilot study of dialectical behaviour therapy guided self-help for binge eating disorder.
Behaviour research and therapy
2013; 51 (11): 723-728
This study examined the efficacy of guided self-help based on dialectical behaviour therapy (DBTgsh) for binge eating disorder (BED). Individuals (88.3% female; mean 42.8 years) were randomized to DBTgsh (n = 30) or wait-list (WL; n = 30). DBTgsh participants received an orientation, DBT manual, and six 20-min support calls over 13 weeks. All participants were assessed pre- and post-treatment using interview and self-report; also, DBTgsh participants were re-assessed six months post-treatment. At treatment end, DBTgsh participants reported significantly fewer past-month binge eating episodes than WL participants (6.0 versus 14.4) and significantly greater rates of abstinence from binge eating (40.0% versus 3.3%). At six-month follow-up, DBTgsh participants reported significantly improved quality of life and reduced ED psychopathology compared to baseline scores. In addition, most improvements in the DBTgsh group were maintained, although binge eating abstinence rates decreased to 30%. These preliminary positive findings indicate that DBTgsh may offer an effective, low-intensity treatment option for BED.

Race/Ethnicity, Education, and Treatment Parameters as Moderators and Predictors of Outcome in Binge Eating Disorder
JOURNAL OF CONSULTING AND CLINICAL PSYCHOLOGY
2013; 81 (4): 710-721
Objective: Binge eating disorder (BED) is prevalent among individuals from minority racial/ethnic groups and among individuals with lower levels of education, yet the efficacy of psychosocial treatments for these groups has not been examined in adequately powered analyses. This study investigated the relative variance in treatment retention and posttreatment symptom levels accounted for by demographic, clinical, and treatment variables as moderators and predictors of outcome. Method: Data were aggregated from 11 randomized, controlled trials of psychosocial treatments for BED conducted at treatment sites across the United States. Participants were N = 1,073 individuals meeting criteria for BED including n = 946 Caucasian, n = 79 African American, and n = 48 Hispanic/Latino participants. Approximately 86% had some higher education; 85% were female. Multilevel regression analyses examined moderators and predictors of treatment retention, Eating Disorder Examination (EDE) global score, frequency of objective bulimic episodes (OBEs), and OBE remission. Results: Moderator analyses of race/ethnicity and education were nonsignificant. Predictor analyses revealed African Americans were more likely to drop out of treatment than Caucasians, and lower level of education predicted greater posttreatment OBEs. African Americans showed a small but significantly greater reduction in EDE global score relative to Caucasians. Self-help treatment administered in a group showed negative outcomes relative to other treatment types, and longer treatment was associated with better outcome. Conclusions: Observed lower treatment retention among African Americans and lesser treatment effects for individuals with lower levels of educational attainment are serious issues requiring attention. Reduced benefit was observed for shorter treatment length and self-help administered in groups. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

Group dialectical behavior therapy adapted for obese emotional eaters; a pilot study
2012; 27 (4): 1141-1147
Dialectical Behavior Therapy (DBT) has been shown to effectively target binge eating disorder (BED). This study pilots the effectiveness of group DBT for obese "emotional eaters" to reduce eating psychopathology and achieve weight maintenance. Thirty-five obese male and female emotional eaters receiving 20 group psychotherapy sessions of DBT adapted for emotional eating were assessed at end-of-treatment and 6 month follow-up for reductions in eating psychopathology and weight maintenance. DBT resulted in significant reductions in emotional eating and other markers of eating psychopathology at the end-of-treatment that were maintained at follow-up. The drop-out rate was very low, with only 1 participant dropping from treatment. Thirty-three (94%) of the sample provided data at every assessment point. Of these, 80% achieved either weight reduction or weight maintenance after treatment and throughout the follow-up period. The effect size for weight reduction was small. This pilot study demonstrates group DBT targeting emotional eating in the obese to be a highly acceptable and effective intervention for reducing eating related psychopathology at both at end-of-treatment and during follow-up. The ability of DBT to limit the upward trajectory of weight gain in obese patients with high degrees of emotional eating suggests that DBT may also help limit the increase or even prevent onset of obesity related morbidity in these patients.

Moderators of dialectical behavior therapy for binge eating disorder: Results from a randomized controlled trial
INTERNATIONAL JOURNAL OF EATING DISORDERS
2012; 45 (4): 597-602
Investigate moderators of a randomized clinical trial of group Dialectical Behavior Therapy for Binge Eating Disorder (DBT-BED) compared to an active comparison group control (ACGT) on the post-treatment outcome of binge frequency after twenty 2-h weekly sessions.Moderation analyses.Participants were 101 adults with BED [mean (SD) age, 52.2 (10.6) years and BMI, 36.4 (8.6)]. Analyses identified two moderators of post-treatment outcome. Participants with (1) Avoidant Personality Disorder or (2) an earlier onset of overweight and dieting (<15 years old) evidenced significantly worsened outcome when treated with ACGT versus DBT-BED.Participants with certain indicators of higher baseline pathology respond better to DBT-BED than ACGT at post-treatment.

Racial/Ethnic Differences in Adults in Randomized Clinical Trials of Binge Eating Disorder
JOURNAL OF CONSULTING AND CLINICAL PSYCHOLOGY
2012; 80 (2): 186-195
Recent studies suggest that binge eating disorder (BED) is as prevalent among African American and Hispanic Americans as among Caucasian Americans; however, data regarding the characteristics of treatment-seeking individuals from racial and ethnic minority groups are scarce. The purpose of this study was to investigate racial/ethnic differences in demographic characteristics and eating disorder symptoms in participants enrolled in treatment trials for BED.Data from 11 completed randomized, controlled trials were aggregated in a single database, the Clinical Trials of Binge Eating Disorder (CT-BED) database, which included 1,204 Caucasian, 120 African American, and 64 Hispanic participants assessed at baseline. Age, gender, race/ethnicity, education, body mass index (BMI), binge eating frequency, and Eating Disorder Examination (EDE) Restraint, Shape, Weight, and Eating Concern subscale scores were examined.Mixed model analyses indicated that African American participants in BED treatment trials had higher mean BMI than Caucasian participants, and Hispanic participants had significantly greater EDE shape, weight, and eating concerns than Caucasian participants. No racial or ethnic group differences were found on the frequency of binge eating episodes. Observed racial/ethnic differences in BED symptoms were not substantially reduced after adjusting for BMI and education. Comparisons between the CT-BED database and epidemiological data suggest limitations to the generalizability of data from treatment-seeking samples to the BED community population, particularly regarding the population with lower levels of education.Further research is needed to assess alternative demographic, psychological, and culturally specific variables to better understand the diversity of treatment-seeking individuals with BED.

Suprathreshold duloxetine for treatment-resistant depression, anorexia nervosa binge-purging type, and obsessive-compulsive disorder: a case report.
Innovations in clinical neuroscience
2012; 9 (3): 13-16
Duloxetine, a serotonin norepinephrine reuptake inhibitor (SNRI) indicated for the treatment of depression, is used for off-label purposes such as treatment-resistant obsessive compulsive disorder, bulimia, and binge eating disorder. Although establishing a dose-response relationship for antidepressants in the treatment of depression is difficult, it is possible that for certain patterns of comorbidity, suprathreshold doses may be important to achieve remission. There is currently a paucity of literature regarding the use of suprathreshold doses of duloxetine in treatment refractory cases. This case report describes a clinical situation in which suprathreshold duloxetine was used to treat a patient with severe depression as well as co-morbid anorexia nervosa binge-purging type and obsessive compulsive disorder. One year after the initial increase to 180mg, the patient's mood remains improved. Our clinical account appears to be only the second case report describing the efficacy of high dose 180mg duloxetine in the management of symptoms refractory to treatment at standard doses.

Does rapid response to two group psychotherapies for binge eating disorder predict abstinence?
BEHAVIOUR RESEARCH AND THERAPY
2011; 49 (5): 339-345
Extend understanding of a rapid response (RR) to treatment by examining its prognostic significance at end-of-treatment (EOT) and 1 year follow-up within two group treatments for binge eating disorder (BED): Dialectical Behavior Therapy for BED (DBT-BED) and an active comparison group therapy (ACGT).101 adults with BED randomized to 20-weeks DBT-BED versus ACGT (Safer, Robinson, & Jo, 2010). RR defined as ≥65% reduction in the frequency of days of binge eating by week 4. RR across and within treatment conditions used to predict binge eating abstinence and secondary outcomes (e.g., binge eating pathology, treatment attrition) at EOT and 1 year follow-up.(1) Significantly higher binge eating abstinence for rapid responders (RR; n = 41) vs. non-rapid responders (non-RRs; n = 60) at EOT (70.7% vs. 33.3%) and 1 year follow-up (70.7% vs. 40.0%), respectively, as well as improvement on most secondary measures (2) Significantly less attrition among RRs vs. non-RRs (3) Significantly higher binge eating abstinence rates at both time points for DBT-RRs vs. DBT-non-RRs, but not for ACGT-RRs vs. ACGT-non-RRs.Current study extends prognostic significance of RR to 1 year follow-up. RR more prominent for those randomly assigned to DBT-BED than ACGT. Implications discussed.

Appetite-Focused Dialectical Behavior Therapy for the Treatment of Binge Eating with Purging: A Preliminary Trial
INTERNATIONAL JOURNAL OF EATING DISORDERS
2011; 44 (3): 249-261
This treatment development study investigated the acceptability and efficacy of a modified version of dialectical behavior therapy (DBT) for bulimia nervosa (BN), entitled appetite focused DBT (DBT-AF).Thirty-two women with binge/purge episodes at least one time per week were randomly assigned to 12 weekly sessions of DBT-AF (n = 18) or to a 6-week delayed treatment control (n = 14). Participants completed the EDE interview and self-report measures at baseline, 6 weeks, and posttreatment.Treatment attrition was low, and DBT-AF was rated highly acceptable. At 6 weeks, participants who were receiving DBT-AF reported significantly fewer BN symptoms than controls. At posttest, 26.9% of the 26 individuals who entered treatment (18 initially assigned and 8 from the delayed treatment control) were abstinent from binge/purge episodes for the past month; 61.5% no longer met full or subthreshold criteria for BN. Participants demonstrated a rapid rate of response to treatment and achieved clinically significant change.Results suggest that DBT-AF warrants further investigation as an alternative to DBT or cognitive behavior therapy for BN.

Use of Mirtazapine in an Adult with Refractory Anorexia Nervosa and Comorbid Depression: A Case Report
INTERNATIONAL JOURNAL OF EATING DISORDERS
2011; 44 (2): 178-181
The objective of this report was to describe an efficacious treatment of an adult with long-standing anorexia nervosa (AN). A 50-year-old woman with an over 7-year history of AN and comorbid major depression had been treated unsuccessfully with numerous psychotropic medications, manualized cognitive behavior therapy, and an intensive outpatient treatment program before referral. After treatment with mirtazapine, she gained weight and her depression improved. A 9-month follow-up revealed a maintenance of these benefits. Mirtazapine may be useful for older, chronically ill patients presenting with AN and comorbid depression.

Outcome From a Randomized Controlled Trial of Group Therapy for Binge Eating Disorder: Comparing Dialectical Behavior Therapy Adapted for Binge Eating to an Active Comparison Group Therapy
2010; 41 (1): 106-120
Dialectical Behavior Therapy for Binge Eating Disorder (DBT-BED) aims to reduce binge eating by improving adaptive emotion-regulation skills. Preliminary findings have been promising but have only compared DBT-BED to a wait-list. To control for the hypothesized specific effects of DBT-BED, the present study compared DBT-BED to an active comparison group therapy (ACGT). Men and women (n=101) meeting DSM-IV BED research criteria were randomly assigned to 20 group sessions of DBT-BED (n=50) or ACGT (n=51). DBT-BED had a significantly lower dropout rate (4%) than ACGT (33.3%). Linear Mixed Models revealed that posttreatment binge abstinence and reductions in binge frequency were achieved more quickly for DBT-BED than for ACGT (posttreatment abstinence rate=64% for DBT-BED vs. 36% for ACGT) though differences did not persist over the 3-, 6-, and 12-month follow-up assessments (e.g., 12-month follow-up abstinence rate=64% for DBT-BED vs. 56% for ACGT). Secondary outcome measures revealed no sustained impact on emotion regulation. Although both DBT-BED and ACGT reduced binge eating, DBT-BED showed significantly fewer dropouts and greater initial efficacy (e.g., at posttreatment) than ACGT. The lack of differential findings over follow-up suggests that the hypothesized specific effects of DBT-BED do not show long-term impact beyond those attributable to nonspecific common therapeutic factors.

A comparison of ethnic groups in the treatment of bulimia nervosa.
2007; 8 (4): 485-491
This exploratory study investigated whether White and ethnic minority bulimic participants differ on key features of eating psychopathology and treatment outcome. Data from a randomized controlled multi-site study comparing the efficacy of either cognitive-behavioral therapy (CBT) or interpersonal therapy (IPT) for 219 women with bulimia nervosa were analyzed. A significant baseline ethnic difference for body mass index (BMI) (p<.001) was found as well as an ethnicity by center interaction for a prior history of depression (p<.05). In addition, there was a significant ethnic difference for the Weight Concerns subscale of the Eating Disorder Examination (EDE). However, once BMI was controlled, this difference did not retain significance. At post-treatment, while all ethnic groups responded with higher abstinence rates to CBT than IPT, an ethnicity by treatment effect was found for the reduction of objective binge eating episodes. Black participants, compared to other groups, showed greater reductions in binge eating episodes when treated with IPT than CBT. Other findings related to secondary outcome measures, though limited by small sample size, are discussed as providing directions for future research.

The relationship of weight suppression and dietary restraint to binge eating in bulimia nervosa
INTERNATIONAL JOURNAL OF EATING DISORDERS
2007; 40 (7): 640-644
Recent research has raised important questions about the relationships between weight suppression (WS) (discrepancy between highest-ever and current weight), dietary restraint, and binge eating in bulimia nervosa (BN).In the current study, these variables were studied cross-sectionally through secondary analyses of baseline data collected in a multi-site treatment study. Participants (N = 182) were treatment-seeking women diagnosed with BN. Dietary restraint and binge eating were measured via the Eating Disorders Examination.WS was directly and dietary restraint was inversely related to frequency of binge eating. The inverse relationship between dietary restraint and binge eating may be explained in part by the fact that the most restrained patients with BN had the greatest desire to lose weight.Implications of these findings for future research on the perpetuation and treatment of BN are discussed.

Designing a control for a behavioral group therapy
2006; 37 (2): 120-130
To evaluate whether the specific techniques of a newly developed behavioral therapy exceed the effects of its common factors (e.g., therapeutic alliance), an ideal comparison control must omit the unique ingredients of the active treatment while possessing the common factors in equal measure. Reviews of the controlled-trial psychotherapy research literature show that such systematic matching is not a common practice. Addressing this gap between theory and practice, we delineate 7 steps for designing a credible control for a recently developed behavioral therapy adapted for binge eating disorder--dialectical behavior therapy (DBT). Our detailed description of matching the common factors to the extent possible and specifically measuring these offers a useful research design template for investigators of controlled behavioral treatment trials.

Weight suppression is a robust predictor of outcome in the cognitive-behavioral treatment of bulimia nervosa
JOURNAL OF ABNORMAL PSYCHOLOGY
2006; 115 (1): 62-67
This study examined weight suppression (difference between highest premorbid weight and pretreatment weight) as a predictor of outcome in 188 outpatients with bulimia nervosa enrolled in a cognitive-behavioral therapy intervention. Participants who dropped out of treatment had significantly higher levels of weight suppression than treatment completers. Of participants who completed treatment, those who continued to engage in binge eating or purging had significantly higher levels of weight suppression than those who were abstinent from bingeing and purging. Results did not change when body mass index, dietary restraint, weight and shape concerns, or other relevant variables were controlled. Relinquishing bulimic behaviors and adopting normal eating patterns may be most feasible for patients who are closest to their highest premorbid weights.

Comparing two measures of eating restraint in bulimic women treated with cognitive-behavioral therapy
INTERNATIONAL JOURNAL OF EATING DISORDERS
2004; 36 (1): 83-88
To examine changes in dietary restraint patterns revealed by the Eating Disorders Examination Restraint subscale (EDE-R) and the Three-Factor Eating Questionnaire Cognitive Restraint scale (TFEQ-CR) in a large sample of women with bulimia nervosa (BN) who completed 18 weeks of cognitive-behavioral therapy (CBT).Data from 134 subjects were obtained from a larger study and analyzed using repeated-measures analysis of variance (ANOVA).The EDE-R showed statistically and clinically significant decreases post-CBT, whereas the TFEQ-CR did not change significantly.This is the first study to directly compare the EDE-R and TFEQ-CR before and after CBT in the same population. The contrasting results suggest the two measures tap different aspects of the dietary restraint construct. The EDE-R may primarily reflect dieting to lose weight whereas the TFEQ-CR may reflect dieting to avoid weight gain. In assessing changes in dietary restraint targeted by CBT for BN, the TFEQ-CR appears less useful.

Predictors of relapse following successful dialectical behavior therapy for binge eating disorder
INTERNATIONAL JOURNAL OF EATING DISORDERS
2002; 32 (2): 155-163
To identify predictors of relapse at 6-month follow-up for women with binge eating disorder (BED).Participants were 32 women with BED who had initially achieved abstinence from binge eating after 20 weeks of dialectical behavior therapy (DBT) adapted for patients with BED. Posttreatment predictor variables included the subscales Restraint, Weight Concerns, and Shape Concerns from the Eating Disorders Examination (EDE), the Emotional Eating Scale score, the Rosenberg Self-Esteem Scale, body mass index, and early versus late age of binge eating onset.The largest effect sizes for predicting relapse were found with early onset of binge eating and higher EDE Restraint scores.Previous findings that earlier age of onset (age 16 years or younger) is linked to less successful treatment outcome are now extended to the 6-month follow-up assessment. The finding that higher restraint scores after treatment predict relapse adds to the literature concerning the role of restraint in patients with BED.

Early body mass index and other anthropometric relationships between parents and children
INTERNATIONAL JOURNAL OF OBESITY
2001; 25 (10): 1532-1536
To assess longitudinally the relationship between measures of adiposity in children over the first 8 y of life with that of their parents and to explore the role of parental adiposity in the development of childhood adiposity.Longitudinal study of measures of adiposity in children.A community sample from three health service systems including 114 children followed annually from infancy to age 8 and their 228 biological parents.Measurements were assessed at baseline for parents (6 months post-partum for mothers) and at regular intervals for children beginning at age 2 months. Measurements included weight, height, triceps skinfold, subscapular skinfold, midarm circumference, waist and hip.The major findings were: (1) significant correlations between parental body mass index (BMI), both maternal and paternal, and their biological offspring first emerged at age 7; (2) children with two overweight parents had consistently elevated BMI compared to children with either no overweight parents or one overweight parent. These differences became significant beginning at age 7.This study supports the hypothesis that familial factors (biological and/or environmental) affecting the development of adiposity emerge at specific ages and are related to the adiposity of both parents.

Prolonged bottle feeding in a cohort of children: Does it affect caloric intake and dietary composition?
2001; 40 (9): 481-487
Little is known about the consequences to children of bottle feeding prolonged beyond age 1 year on caloric intake and overall dietary composition. To obtain these data, 165 children, followed up from infancy, were assessed in these respects for a 24-hour period at age 3 1/2 years. Bottle-fed children (n = 14) consumed more milk than their weaned counterparts (p < 0.001), had a higher mean daily calcium intake (p < 0.05), received fewer calories from carbohydrates (p = 0.034), and received a greater percentage of calories from protein (p = 0.033). There were no significant differences between the groups in total caloric intake, total iron intake, total volume ofjuice, or calories from fat. Pediatricians questioned about the effects of continuing to offer children nutritive liquids from bottles as well as cups (versus offering cups alone) may inform parents that this feeding practice is associated with significantly greater milk consumption and daily calcium intake. However, this study could not find evidence that prolonged bottle feeding at age 3 1/2 years is associated with a significantly decreased total daily iron intake or an increased risk for factors associated with adiposity such as a greater daily calorie intake, a higher body mass index, or greater percentage of total calories derived from fat.

Dialectical behavior therapy adapted for bulimia: A case report
INTERNATIONAL JOURNAL OF EATING DISORDERS
2001; 30 (1): 101-106
This case report describes the application of dialectical behavior therapy (DBT) to the treatment of bulimia nervosa in a 20-session manualized therapy.The treatment, based on an affect regulation model of eating disorders, was developed to teach emotion regulation skills to replace eating-disordered behaviors. The patient, a 36-year-old woman, had a long history of binge eating and purging that had not responded to 2 years of counseling. In the 4 weeks before treatment began, she reported 13 objective binges and 21 purging episodes.Upon initiating DBT, her binge eating and purging rapidly declined. She achieved abstinence by the fifth week of treatment and maintained it through treatment. In the 6 months following treatment, she reported a total of two objective binge episodes and two purge episodes.

Dialectical behavior therapy for bulimia nervosa
AMERICAN JOURNAL OF PSYCHIATRY
2001; 158 (4): 632-634
The effects of dialectical behavior therapy adapted for the treatment of binge/purge behaviors were examined.Thirty-one women (averaging at least one binge/purge episode per week) were randomly assigned to 20 weeks of dialectical behavior therapy or 20 weeks of a waiting-list comparison condition. The manual-based dialectical behavior therapy focused on training in emotion regulation skills.An intent-to-treat analysis showed highly significant decreases in binge/purge behavior with dialectical behavior therapy compared to the waiting-list condition. No significant group differences were found on any of the secondary measures.The use of dialectical behavior therapy adapted for treatment of bulimia nervosa was associated with a promising decrease in binge/purge behaviors.

AFFINITY LABELING OF BOVINE LIVER GLUTAMATE-DEHYDROGENASE WITH 8-[(4-BROMO-2,3-DIOXOBUTYL)THIO]ADENOSINE 5'-DIPHOSPHATE AND 5'-TRIPHOSPHATE
1990; 29 (30): 7112-7118
Bovine liver glutamate dehydrogenase reacts with 8-[(4-bromo-2,3-dioxobutyl)thio]adenosine 5'-diphosphate (8-BDB-TA-5'-DP) and 5'-triphosphate (8-BDB-TA-5'-TP) to yield enzyme with about 1 mol of reagent incorporated/mol of enzyme subunit. The modified enzyme is catalytically active but has decreased sensitivity to inhibition by GTP, reduced extent of activation by ADP, and diminished inhibition by high concentrations of NADH. Since modified enzyme, like native glutamate dehydrogenase, reversibly binds more than 1 mol each of ADP and GTP, it is unlikely that 8-BDB-TA-5'-TP reacts directly within either the ADP or GTP regulatory sites. The rate constant for reaction of enzyme exhibits a nonlinear dependence on reagent concentration with KD = 89 microM for 8-BDB-TA-5'-TP and 240 microM for 8-BDB-TA-5'-DP. The ligands ADP and GTP alone and NADH alone produce only small decreases in the rate constant for the reaction of enzyme with 8-BDB-TA-5'-TP, but the combined addition of 5 mM NADH + 200 microM GTP reduces the reaction rate constant more than 10-fold and the reagent incorporation to about 0.1 mol/mol of enzyme subunit. These results suggest that 8-BDB-TA-5'-TP reacts as a nucleotide affinity label in the region of the GTP-dependent NADH regulatory site of bovine liver glutamate dehydrogenase.
