Does interpersonal therapy help patients with binge eating disorder who fail to respond to cognitive-behavioral therapy?
The aim of this quasi-experimental study was to examine the effectiveness of group interpersonal therapy (IPT) in treating overweight patients with binge eating disorder who did not stop binge eating after 12 weeks of group cognitive-behavioral therapy (CBT). Participants in this study were randomly allocated to either group CBT or to an assessment-only control group. After 12 weeks of treatment with CBT, 55% of participants met criteria for improvement and began 12 weeks of weight loss therapy, whereas the nonresponders began 12 weeks of group IPT. Over the 24-week period, participants who received treatment reduced binge eating and weight significantly more than the waiting-list control group. However, IPT led to no further improvement for those who did not improve with CBT. Predictors of poor outcome were early onset of, and more severe, binge eating.
