Linardon J, et al. - Researchers planned this meta-analysis of randomized controlled trials to determine the prevalence of patients who abstain from binge eating and/or purging following all psychological treatments for bulimia nervosa (BN). They also tested whether these abstinence estimates were moderated by the type of treatment modality delivered, the definition of abstinence applied, and trial quality. Findings revealed that even after receiving the most empirically-supported treatments, over 60% of patients fail to fully abstain from core BN symptoms. They thereby highlight the urgency toward improving the effectiveness of psychological treatments for BN.
