The extent to which CBT tested in controlled research settings generalizes to real\u2010world circumstances is unknown. We conducted a meta\u2010analysis of nonrandomized studies of CBT for eating disorders, with three aims: (a) to estimate the prevalence of patients who achieve binge\u2010purge abstinence after CBT in routine practice; (b) to compare these estimates with those derived from two recent meta\u2010analyses of randomized controlled trials (RCTs) of CBT for bulimia nervosa (BN) and binge\u2010eating disorder (BED); (c) to examine whether the degree of clinical representativeness of studies was associated with effect sizes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>Twenty\u2010seven studies, mainly involving BN, were included.

The intention\u2010to\u2010treat (ITT) estimate was lower (34.6% [95% CI\u2009=\u200929.3\u201340.4]). However, abstinence rates varied across diagnoses, such that the completer and ITT analysis abstinence estimates were larger for BED samples (completer\u2009=\u200950.2%, 95% CI\u2009=\u200929.4\u201370.9; ITT\u2009=\u200947.2%, 95% CI\u2009=\u200929.8\u201365.2) than for BN (completer\u2009=\u200937.4%, 95% CI\u2009=\u200929.1\u201346.5; ITT\u2009=\u200929.8%, 95% CI\u2009=\u200924.9\u201335.3) and atypical eating disorder samples (completer\u2009=\u200937.8%, 95% CI\u2009=\u200920.2\u201359.3; ITT\u2009=\u200928.8%, 95% CI\u2009=\u200918.2\u201342.4).
