About this study

Official title: A Randomized Comparison of Group-Behavioral Therapy and Group Interpersonal Psychotherapy for the Treatment of Overweight Individuals With Binge-Eating Disorder

Cognitive-behavioral therapy (CBT) has documented efficacy for the treatment of binge eating disorder (BED). Interpersonal psychotherapy (IPT) has been shown to reduce binge eating but its long-term impact and time course on other BED-related symptoms remain largely unknown. This study compares the effects of group CBT and group IPT across BED-related symptoms among overweight individuals with BED.

Cognitive-behavioral therapy (CBT) has documented efficacy for the treatment of binge eating disorder (BED). Interpersonal psychotherapy (IPT) has been shown to reduce binge eating but its long-term impact and time course on other BED-related symptoms remain largely unknown. This study compares the effects of group CBT and group IPT across BED-related symptoms among overweight individuals with BED. METHODS: One hundred sixty-two overweight patients meeting DSM-IV criteria for BED were randomly assigned to 20 weekly sessions of either group CBT or group IPT. Assessments of binge eating and associated eating disorder psychopathology, general psychological functioning, and weight occurred before treatment, at posttreatment, and at 4-month intervals up to 12 months following treatment. RESULTS: Binge-eating recovery rates were equivalent for CBT and IPT at posttreatment (64 [79%] of 81 vs 59 [73%] of 81) and at 1-year follow-up (48 [59%] of 81 vs 50 [62%] of 81). Binge eating increased slightly through follow-up but remained significantly below pretreatment levels. Across treatments, patients had similar significant reductions in associated eating disorders and psychiatric symptoms and maintenance of gains through follow-up. Dietary restraint decreased more quickly in CBT but IPT had equivalent levels by later follow-ups. Patients' relative weight decreased significantly but only slightly, with the greatest reduction among patients sustaining recovery from binge eating from posttreatment to 1-year follow-up. CONCLUSIONS: Group IPT is a viable alternative to group CBT for the treatment of overweight patients with BED. Although lacking a nonspecific control condition limits conclusions about treatment specificity, both treatments showed initial and long-term efficacy for the core and related symptoms of BED.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To investigate the short and long-term efficacy of two treatments for binge eating among the overweight: Group Cognitive-Behavior (CBT) and Group Interpersonal Therapy (IPT).. It is what the study was designed to measure, not a finding.
