Abstract

The purpose of this study was to perform a receiver operator characteristics (ROC) analysis on a treatment sample from a randomized controlled treatment trial of participants with binge eating disorder (BED). An ROC analysis was completed with 179 adults in a 20-week treatment trial for BED to predict abstinence from binge eating at end of treatment. Percent reductions in binge eating episodes were examined following weeks 1 through 10 of treatment. The rate of percent decrease in binge eating episodes during treatment for BED was a significant predictor of clinical outcome at end of treatment. Participants who demonstrated a 15% reduction in binge eating episodes at week one were more likely to respond positively to treatment and achieve clinical remission. Findings from the current study suggest that a significant reduction in binge eating during the first week of treatment may be predictive of end of treatment remission in those with BED.
