Cognitive-behavioural treatment for women who binge eat.

PURPOSE: A dietitian-administered, shortened form of the Apple and Agras cognitive-behavioural therapy (CBT) method was evaluated in a group setting to determine its effect on improving obese women's self-esteem and reducing binge-eating behaviours, depression, and negative body image. METHODS: Participants were recruited through newspaper and radio advertisements. Respondents who met study selection criteria were randomly assigned to either a CBT group (n=13) or a delayed group (D-CBT) (n=9). The treatment was administered over six weekly sessions to the CBT group, and then twice weekly over three weeks to the D-CBT group. Two measures of bingeing behaviour (severity and frequency), three measures of mood (depression, body image, and self-esteem), and body weight were assessed. RESULTS: The intervention did not result in any changes in body weight. There were statistically significant and clinically important changes after treatment (p<0.05) for all five measures. Binge-eating severity and frequency decreased, depression decreased, body image improved, and self-esteem improved. All changes were greater in the six-week treatment group. CONCLUSIONS: The dietitian-administered, group setting CBT program is effective for reducing binge eating and improving emotional state in obese women.
