Abstract
Objective The aim of the study was to assess the long-term efficacy of Cognitive-Behavioral Treatment (CBT) and Behavioral Weight-Loss-Treatment (BWLT) in patients with binge eating disorder (BED) and to identify potential predictors of long-term treatment success. Method In a sample of overweight to obese BED patients from a randomized comparative trial we evaluated the efficacy of four months of CBT or BWLT, followed by 12 months extended care, and a final follow-up assessment 6 years after the end of active treatment. Outcomes included binge eating, eating disorder pathology, depressive feelings, and body mass index. Results After a strong improvement during active treatment, outcomes worsened during follow-up, yet remained improved at 6-year follow-up relative to pretreatment values. Long-term effects between CBT and BWLT were comparable. Rapid response during the early treatment phase was the only characteristic that was predictive of favorable treatment outcome in the long term. Conclusions Both CBT and BWLT can be considered to be comparably efficacious in the long-term. Patients not responding strongly enough during the first four therapy sessions might be in need of tailored interventions early during the treatment phase.
