Summary
Cognitive-behavioral therapy (CBT) effectively treated binge eating in women who do not purge. CBT significantly reduced binge eating episodes and increased abstinence rates compared to a waiting list control group.
Area of Science:
- Psychology
- Clinical Psychology
- Behavioral Science
Background:
- Binge eating disorder (BED) is a significant public health concern.
- Effective treatments for individuals with BED who do not engage in purging behaviors are crucial.
- Cognitive-behavioral therapy (CBT) is a leading treatment for eating disorders.
Purpose of the Study:
- To evaluate the initial efficacy of cognitive-behavioral therapy (CBT) for binge eating in individuals who do not purge.
- To compare CBT outcomes against a waiting-list control group.
Main Methods:
- Forty-four female participants with binge eating were randomized to either CBT or a waiting-list (WL) control.
- Treatment consisted of 10 weekly group sessions.
- Assessments were conducted at posttreatment and 10-week follow-up.
Main Results:
- At posttreatment, 79% of CBT participants achieved abstinence from binge eating, with a 94% decrease in binge episodes.
- Waiting-list participants showed a nonsignificant 9% reduction in binge eating and 0% abstinence rate.
- Following treatment, WL participants showed an 85% reduction in binge episodes and a 73% abstinence rate.
Conclusions:
- Cognitive-behavioral therapy (CBT) is an effective treatment for binge eating in individuals who do not purge.
- Treatment gains were maintained at a 10-week follow-up, although some increase in binge eating was observed.
- CBT offers a promising therapeutic option for this specific population.
