Abstract

Abstract : Objective: To evaluate the efficacy, as well as potential moderators and mediators, of a revised acceptance‐based behavioral treatment (ABT) for obesity, relative to standard behavioral treatment (SBT). Methods: Participants with overweight and obesity ( n = 190) were randomized to 25 sessions of ABT or SBT over 1 year. Primary outcome (weight), mediator, and moderator measurements were taken at baseline, 6 months, and/or 12 months, and weight was also measured every session. Results: Participants assigned to ABT attained a significantly greater 12‐month weight loss (13.3% ± 0.83%) than did those assigned to SBT (9.8% ± 0.87%; P = 0.005). A condition by quadratic time effect on session‐by‐session weights ( P = 0.01) indicated that SBT had a shallower trajectory of weight loss followed by an upward deflection. ABT participants were also more likely to maintain a 10% weight loss at 12 months (64.0% vs. 48.9%; P = 0.04). No evidence of moderation was found. Results supported the mediating role of autonomous motivation and psychological acceptance of food‐related urges. Conclusions: Behavioral weight loss outcomes can be improved by integrating self‐regulation skills that are reflected in acceptance‐based treatment, i.e., tolerating discomfort and reduction in pleasure, enacting commitment to valued behavior, and being mindfully aware during moments of decision‐making.
