Objective-Despite proven efficacy of cognitive-behavioral therapy (CBT) for treating eating disorders with binge eating as the core symptom, few patients receive CBT in clinical practice. Our blended efficacy-effectiveness study sought to evaluate whether a manual-based guided self-help form of CBT (CBT-GSH), delivered in 8 sessions in a Health Maintenance Organization setting over a 12-week period by masters level interventionists, is more effective than treatment as usual (TAU).Method-In all, 123 individuals (mean age = 37.2, 91.9% female, 96.7% non-Hispanic White) were randomized, including 10.6% with bulimia nervosa (BN), 48% with Binge Eating Disorder (BED), and 41.4% with recurrent binge eating in the absence of BN or BED. Baseline, post-treatment, and 6-and 12 month follow-up data were used in intent-to-treat analyses. At 12-month follow-up, CBT-GSH resulted in greater abstinence from binge eating (64.2%) than TAU (44.6%, Number Needed to Treat = 5), as measured by the Eating Disorder Examination (EDE, Fairburn & Cooper, 1993). Secondary outcomes reflected greater improvements in the CBT-GSH group in dietary restraint (d = .30), eating-, shape-, and weight concern (d's = .54, 1.01, .49) (measured by the EDE-Questionnaire, respectively, Fairburn & Beglin, 2008), depression (d = .56) (Beck Depression Inventory, Beck, Steer, & Garbin, 1988), and social adjustment (d = .58) (Work and Social Adjustment Scale, Mundt, Marks, Shear, & Greist, 2002), but not weight change.Correspondence concerning this article should be addressed to Ruth Striegel-Moore, Department of Psychology, Wesleyan University, Middletown, CT 06459. rstriegel@wesleyan.edu.

NIH-PA Author ManuscriptConclusions-CBT-GSH is a viable first-line treatment option for the majority of patients with recurrent binge eating who do not meet diagnostic criteria for BN or anorexia nervosa.Keywords binge eating; cognitive behavior therapy; guided self-help; effectivenessCognitive-behavioral therapy (CBT) has been shown to be an effective treatment for bulimia nervosa (BN) and binge eating disorder (BED) Shapiro et al., 2007;Wilson, Grilo, & Vitousek, 2007) and has been recommended as the psychological treatment of choice for these disorders (Wilson & Shafran, 2005). Yet, only a minority of patients receives this treatment (Currin, et al., 2007...
