Abstract

Objective: The aim of this study was to replicate and extend results of a previous blended efficacy and effectiveness trial of a low-intensity, manual-based guided self-help form of cognitive-behavioral therapy (CBTGSH) for the treatment of binge eating disorders in a large health maintenance organization (HMO) and to compare them with usual care. Methods: To extend previous findings, the investigators modified earlier recruitment and assessment approaches and conducted a randomized clinical trial to better reflect procedures that may be reasonably carried out in real-world practices. The intervention was delivered by master's-level interventionists to 160 female members of a health maintenance organization who met diagnostic criteria for recurrent binge eating. Data collected at baseline, immediately posttreatment, and at six- and 12-month follow-ups were used in intent-to-treat analyses. Results: At the 12-month follow-up, CBT-GSH resulted in greater remission from binge eating (35%, N=26) than usual care (14%, N=10) (number needed to treat=5). The CBT-GSH group also demonstrated greater improvements in dietary restraint (d=.71) and eating, shape, and weight concerns (d=1.10, 1.24, and .98, respectively) but not weight change. Conclusions: Replication of the pattern of previous findings suggests that CBT-GSH is a robust treatment for patients with recurrent binge eating. The magnitude of changes was significantly smaller than in the original study, however, suggesting that patients recruited and assessed with less intensive procedures may respond differently from their counterparts enrolled in trials requiring more comprehensive procedures.
