Integrative Response Therapy for Binge Eating Disorder.

Area of Science:

• Psychiatry and Behavioral Science
• Clinical Psychology
• Public Health

Background:

• Binge Eating Disorder (BED) is a chronic condition with significant public health implications, characterized by psychopathology and disability.
• Existing specialty treatments for BED are effective but limited in public health utility due to time and cost demands.
• Guided Self-Help (GSH) treatments offer a promising, accessible, and cost-effective alternative for BED management.

Purpose of the Study:

• To describe Integrative Response Therapy (IRT), a novel group-based GSH treatment for BED.
• To evaluate the initial promise of IRT, incorporating affect regulation models into BED treatment.
• To assess the efficacy and acceptability of IRT in a pilot sample of adults with BED.

Main Methods:

• IRT is a group-based guided self-help intervention grounded in the affect regulation model of binge eating.
• A pilot study was conducted with adult participants meeting DSM IV criteria for BED.
• Data collected included abstinence rates, binge days, and scores on the Eating Disorder Examination Questionnaire and Emotional Eating Scale.

Main Results:

• Post-treatment and 3-month follow-up abstinence rates were 54% and 67%, respectively.
• Significant reductions in binge days were observed from baseline to post-treatment (p<.001) and follow-up (p<.001).
• All subscales of the Eating Disorder Examination Questionnaire and Emotional Eating Scale significantly decreased post-treatment.

Conclusions:

• IRT demonstrates initial promise as an effective and acceptable treatment for Binge Eating Disorder.
• The treatment's focus on affect regulation appears beneficial for reducing binge eating behaviors.
• Further investigation into IRT's longer-term efficacy is underway in a randomized controlled trial.
