Summary
Emotion-related treatments significantly reduce binge eating and improve emotion regulation in patients. These positive effects on binge eating disorder are maintained long-term, showing promise for effective therapy.
Area of Science:
- Psychology
- Psychiatry
- Behavioral Science
Background:
- Emotions can trigger binge eating, which is often used as a maladaptive emotion regulation strategy.
- Investigating emotion-focused interventions is crucial for understanding binge eating disorder (BED) treatment.
Purpose of the Study:
- To systematically review and meta-analyze the efficacy of emotion-related treatments for individuals with binge eating.
- To identify potential factors influencing treatment outcomes in binge eating.
Main Methods:
- Systematic review and meta-analysis of 38 studies (31 in meta-analysis) on emotion-related treatments for binge eating.
- Primary outcome: change in binge eating frequency. Secondary outcomes: eating disorder pathology and emotion regulation.
- Investigated influencing factors: BMI, diagnosis, treatment type, age, sex.
Main Results:
- Significant reductions in binge eating frequency were observed post-treatment.
- Emotion-related treatments outperformed waitlist controls and were comparable to active controls.
- Improvements in binge eating, eating disorder pathology, and emotion regulation were noted, with effects stable at follow-up (1-12 months).
Conclusions:
- Emotion-related treatments show significant promise for treating binge eating and improving emotion regulation.
- Emotion regulation appears to be a key mechanism of change in these interventions.
- Treatment efficacy was not significantly influenced by factors like BMI, diagnosis, or demographics.

Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert...
