The report by Halmi and colleagues1 on "relapse" in bulimia nervosa is of considerable importance since it raises serious doubts about the clinical value of cognitive behavior therapy (CBT), the leading evidence-based treatment for this eating disorder.2 The finding of note is that 44% of those participants with an excellent posttreatment outcome (total remission from binge eating and purging) relapsed within just 4 months of completing treatment. However, we suggest that to interpret this observation, 2 points need to be clarified.
