Eating attitudes and behaviors in 1,435 South African Caucasian and non-Caucasian college students.

OBJECTIVE: The purpose of this study was to examine the presence and severity of eating disorder pathology in students representing South Africa's ethnically and culturally diverse population. METHOD: A questionnaire survey, which involved the Eating Attitude Test and the Bulimic Investigatory Test, was administered to 1,435 South African college students (739 Caucasian and 696 non-Caucasian) from six universities in two urban centers. RESULTS: Black students scored significantly higher than the other ethnic groups on these measures. In addition, a comparable percentage of black and Caucasian female students had scores within the clinical range on these scales. Male students scored consistently lower than female students. CONCLUSIONS: This study's findings challenge the notion that eating disorders are primarily a Western, Caucasian phenomenon and raise the possibility that the risk of eating disorders may increase in developing societies.

Dialectical behavior therapy for bulimia nervosa.

OBJECTIVE: The effects of dialectical behavior therapy adapted for the treatment of binge/purge behaviors were examined. METHOD: 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. RESULTS: 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. CONCLUSIONS: The use of dialectical behavior therapy adapted for treatment of bulimia nervosa was associated with a promising decrease in binge/purge behaviors.

Pharmacologic and cognitive-behavioral treatment for bulimia nervosa: a controlled comparison.

OBJECTIVE: This study examined the relative effectiveness of desipramine, cognitive-behavioral therapy, and their combination in the treatment of bulimia nervosa, together with the effects of withdrawing medication after two different lengths of treatment. METHOD: Seventy-one patients meeting DSM-III-R criteria for bulimia nervosa, recruited from an eating disorders clinic or by advertisements, were assigned at random to one of five groups: desipramine (withdrawn at 16 or 24 weeks), combined treatment (medication withdrawn at 16 or 24 weeks), and cognitive-behavioral therapy (15 sessions). All treatments were conducted individually in an outpatient clinic. The primary outcome measures were binge eating and purging rates assessed at pretreatment, 16, 24, and 32 weeks. The results were analyzed as three groups (medication, cognitive-behavioral therapy, and combined treatment) at 16 weeks and as five groups at subsequent assessments. RESULTS: At 16 weeks, both cognitive-behavioral therapy and the combined treatment were superior to medication given for 16 weeks in reducing binge eating and purging. At 32 weeks, however, only the combined 24-week treatment was superior to medication given for 16 weeks. The combined treatment was also more effective in reducing dietary preoccupation and hunger. Continuing cognitive-behavioral therapy appeared to prevent relapse in patients withdrawn from medication at 16 weeks. CONCLUSIONS: Overall, the results favor the use of a combination of medication and cognitive-behavioral therapy in the treatment of bulimia nervosa, with medication continued for at least 24 weeks.

One-year follow-up of psychosocial and pharmacologic treatments for bulimia nervosa.

BACKGROUND: This study examined the outcome 1-year posttreatment of the use of desipramine, cognitive-behavioral therapy (CBT), and their combination in the treatment of bulimia nervosa. METHOD: Sixty-one patients meeting DSM-III-R criteria for bulimia nervosa were randomly assigned to one of five groups--desipramine (withdrawn at 16 or 24 weeks), CBT (18 sessions), or the combined treatment (18 sessions of CBT plus desipramine withdrawn at 16 or 24 weeks)--and were followed to 1-year posttreatment. RESULTS: At 1-year follow-up, both the combined 24-week treatment and CBT alone were significantly superior in reducing binge eating to desipramine given for 16 weeks. The combined treatment was also superior to 16 weeks of desipramine in reducing emotionally driven eating and dietary restraint. Only 18% (2 of 11) of those receiving 16 weeks of desipramine were free of binge eating and purging at follow-up compared with 78% (7 of 9) of those receiving the combined 24-week treatment. The other groups fell between these two extremes. CONCLUSION: With the exception of the group treated for 16 weeks with desipramine alone, maintenance of improvement appeared satisfactory with all the treatments. Since the poorest results were found with 16 weeks of desipramine treatment, this study suggests that desipramine should be continued for at least 24 weeks either alone or combined with CBT. The broadest gain in reducing the psychopathology associated with bulimia nervosa was found with the combined 24-week treatment.

Psychiatric comorbidity in women with binge eating disorder: prevalence rates from a non-treatment-seeking sample.

This study provides estimates of comorbid psychiatric disorders in women with binge eating disorder (BED). Sixty-one BED and 60 control participants, who were recruited from the community, completed the Structured Clinical Interview for DSM-III-R Axis I and Axis II disorders and self-report measures of eating and general psychiatric symptomatology. Regarding psychiatric diagnoses, women with BED had higher lifetime prevalence rates for major depression, any Axis I disorder, and any Axis II disorder relative to controls. BED women also evidenced greater eating and psychiatric symptomatology than did controls. Results suggest that the prevalence of comorbid psychiatric disorders in BED may be lower than previously indicated by clinical studies.

Dialectical behavior therapy for binge eating disorder.

This study evaluated the use of dialectical behavior therapy (DBT) adapted for binge eating disorder (BED). Women with BED (N = 44) were randomly assigned to group DBT or to a wait-list control condition and were administered the Eating Disorder Examination in addition to measures of weight, mood, and affect regulation at baseline and posttreatment. Treated women evidenced significant improvement on measures of binge eating and eating pathology compared with controls, and 89% of the women receiving DBT had stopped binge eating by the end of treatment. Abstinence rates were reduced to 56% at the 6-month follow-up. Overall, the findings on the measures of weight, mood, and affect regulation were not significant. These results support further research into DBT as a treatment for BED.

Cognitive-behavioral treatment with and without exposure plus response prevention in the treatment of bulimia nervosa: a reply to Leitenberg and Rosen.

In this reply to Leitenberg and Rosen (1989), we conclude that the evidence that response prevention of vomiting adds significantly to the efficacy of cognitive-behavioral treatment of bulimia nervosa is not strong. In this context and given the finding in our previous study (Agras, Schneider, Arnow, Raeburn, & Telch, 1989) that the addition of response prevention did not increase the efficacy of cognitive-behavioral treatment and may have reduced it, we believe that our cautionary note concerning the addition of response prevention to cognitive-behavioral treatment should stand.

Cognitive-behavioral and response-prevention treatments for bulimia nervosa.

This study was designed to assess the additive effects of major components of cognitive-behavioral treatment for bulimia nervosa. Seventy-seven female patients with bulimia nervosa were allocated at random to one of four conditions: wait-list control, self-monitoring of caloric intake and purging behaviors, cognitive-behavioral treatment, and cognitive-behavioral treatment combined with response prevention of vomiting. In the treatment conditions, participants were seen individually for fourteen 1-hr sessions over a 4-month period. All the treatment groups showed significant improvement, whereas the wait-list control group did not. Cognitive-behavioral treatment was, however, the most successful in reducing purging and in promoting positive psychological changes. Fifty-six percent of participants in this condition ceased binge eating and purging by the end of treatment, and the frequency of purging declined by 77.2% during the same period. Of the three treatment conditions, only cognitive-behavioral treatment was superior to the wait-list control. At the 6-month follow-up, 59% of the cognitive-behavioral group were abstinent, and purging had declined by 80%. Cognitive-behavioral treatment was significantly superior to the other treatment groups at this time. Thus, the addition of response prevention of vomiting did not enhance the efficacy of cognitive-behavioral treatment, and the evidence suggests that it may have had a deleterious effect.

One-year follow-up of cognitive-behavioral therapy for obese individuals with binge eating disorder.

The results of a 1-year posttreatment follow-up of 93 obese women diagnosed as having binge eating disorder (BED) and treated with group cognitive-behavioral therapy (CBT) followed by weight loss treatment are described. The group as a whole maintained both reductions in binge eating and abstinence rates fairly well. However, they regained the weight lost during treatment. Those who stopped binge eating during CBT maintained a weight loss of 4.0 kg over the follow-up period. In contrast, those who continued to binge gained 3.6 kg. Twenty-six percent of those abstinent after CBT met criteria for BED at follow-up and had gained weight, whereas the remaining 74% had lost weight. Stopping binge eating appears critical to sustained weight loss in BED.

Group cognitive-behavioral treatment for the nonpurging bulimic: an initial evaluation.

This study tested the initial effects of cognitive-behavioral therapy for binge eating in Ss who do not purge. Forty-four female binge eaters were randomized to either cognitive-behavioral treatment (CB) or a waiting-list (WL) control. Treatment was administered in small groups that met for 10 weekly sessions. At posttreatment a significant difference was found, with 79% of CB Ss reporting abstinence from binge eating and a 94% decrease in binge eating compared with a nonsignificant reduction (9%) in binge eating and zero abstinence rate in WL Ss. Following the posttest assessment, WL Ss were treated and evidenced an 85% reduction in binge episodes and a 73% abstinence rate. Binge eating significantly increased at 10-week follow-up for initially treated Ss; however, the frequency remained significantly improved compared with baseline levels.

Group cognitive-behavioral therapy and group interpersonal psychotherapy for the nonpurging bulimic individual: a controlled comparison.

This study evaluated the effectiveness of group cognitive-behavioral treatment (CBT) and group interpersonal psychotherapy (IPT) for binge eating. Fifty-six women with nonpurging bulimia were randomly assigned to 1 of 3 groups: CBT, IPT, or a wait-list control (WL). Treatment was administered in small groups that met for 16 weekly sessions. At posttreatment, both group CBT and group IPT treatment conditions showed significant improvement in reducing binge eating, whereas the WL condition did not. Binge eating remained significantly below baseline levels for both treatment conditions at 6-month and 1-year follow-ups. These data support the central role of both eating behavior and interpersonal factors in the understanding and treatment of bulimia.

Does interpersonal therapy help patients with binge eating disorder who fail to respond to cognitive-behavioral therapy?

The aim of this quasi-experimental study was to examine the effectiveness of group interpersonal therapy (IPT) in treating overweight patients with binge eating disorder who did not stop binge eating after 12 weeks of group cognitive-behavioral therapy (CBT). Participants in this study were randomly allocated to either group CBT or to an assessment-only control group. After 12 weeks of treatment with CBT, 55% of participants met criteria for improvement and began 12 weeks of weight loss therapy, whereas the nonresponders began 12 weeks of group IPT. Over the 24-week period, participants who received treatment reduced binge eating and weight significantly more than the waiting-list control group. However, IPT led to no further improvement for those who did not improve with CBT. Predictors of poor outcome were early onset of, and more severe, binge eating.

Maintenance following a very-low-calorie diet.

The authors posed 2 questions in this randomized study of maintenance procedures in which participants were followed for 15 months after completion of a very-low-calorie diet: Would stimulus narrowing during the reintroduction of solid food, achieved by the use of prepackaged foods, improve weight losses and the maintenance of those losses as compared with the use of regular food? Would reintroduction of foods dependent on progress in losing or maintaining weight be superior to reintroduction on a time-dependent basis? Neither the stimulus narrowing condition nor the reintroduction procedure enhanced either maximum weight loss or maintenance of those losses. The stimulus narrowing condition appeared to be poorly tolerated; compliance and attendance were poorer in this condition than in the regular food condition.

Comparing the cost effectiveness of psychiatric treatments: bulimia nervosa.

We conducted an exploratory post hoc study that compared the cost effectiveness of five treatments for bulimia nervosa: 15 weeks of cognitive behavioral therapy (CB) followed by three monthly sessions, 16 weeks (Med16) and 24 weeks (Med24) of desipramine (< or = 300 mg/day), and CB combined with desipramine for those durations (Combo16 and Combo24). We illustrate how a treatment's cost effectiveness varies according to when evaluation is done and how effectiveness and cost are defined. At 32 weeks, Med16 appears the most cost-effective treatment, and Combo16 appears the least. At 1 year, Med24 appears the most cost-effective treatment, and Combo16 appears the least. Using this post hoc analysis as an example, we discuss the pitfalls and limitations of cost-effectiveness analysis of psychiatric treatments.

Role of cognitive appraisal in panic-related avoidance.

The present study examined several dimensions of panic cognitions to test whether panic appraisals predict phobicity among panic sufferers. Thirty-five patients meeting DSM-III-R criteria for panic disorder with minimal or no phobic avoidance were compared to 40 patients meeting DSM-III-R criteria for panic disorder with agoraphobia (severe). The two groups looked strikingly similar on measures of panic symptoms, panic frequency and panic severity. As expected, patients diagnosed as having panic disorder with agoraphobia reported significantly more depression and phobic avoidance than patients with PD. Striking differences emerged on each of the following panic appraisal dimensions: (a) anticipated panic, (b) perceived consequences of panic, and (c) perceived self-efficacy in coping with panic. In each case, patients with panic disorder and agoraphobia reported significantly more dysfunctional panic appraisals than patients with panic disorder and no avoidance. Of those panic appraisal dimensions studied, anticipated panic emerged as the most potent correlate of agoraphobic avoidance. These findings support the hypothesis that cognitive appraisal factors may play an important role in the genesis or maintenance of phobic avoidance among panic patients.

A comparison of cessation strategies for the outpatient alcoholic.

The present study compared the relative effectiveness of group-administered covert sensitization, supportive group therapy, and a non-specific control in disrupting the drinking response of 28 outpatient alcoholics. Multiple measures of treatment outcome were examined to insure a more comprehensive assessment of treatment effects. These included (a) randomly sampled blood/alcohol levels, (b) reported mean daily drinking frequencies and (c) reported urges to drink. Results indicated that supportive group therapy was significantly more effective than the other two treatments in reducing subjects' reported daily drinking. No significant differences were found on measures of blood/alcohol concentration or subjects' ratings of frequency of urges to drink. All three groups reported significant improvement over time on urge ratings. Results seriously question the efficacy of covert sensitization in helping outpatient alcoholics reduce their intake of alcohol.

Development and validation of the Eating Disorder Diagnostic Scale: a brief self-report measure of anorexia, bulimia, and binge-eating disorder.

This article describes the development and validation of a brief self-report scale for diagnosing anorexia nervosa, bulimia nervosa, and binge-eating disorder. Study 1 used a panel of eating-disorder experts and provided evidence for the content validity of this scale. Study 2 used data from female participants with and without eating disorders (N = 367) and suggested that the diagnoses from this scale possessed temporal reliability (mean kappa = .80) and criterion validity (with interview diagnoses; mean kappa = .83). In support of convergent validity, individuals with eating disorders identified by this scale showed elevations on validated measures of eating disturbances. The overall symptom composite also showed test-retest reliability (r = .87), internal consistency (mean alpha = .89), and convergent validity with extant eating-pathology scales. Results implied that this scale was reliable and valid in this investigation and that it may be useful for clinical and research applications.
