Feasibility, Acceptability, and Exploratory Outcomes of Acceptance and Commitment Therapy for Binge Eating Symptoms...

Overweight and obesity are disabling problems for veterans and place a heavy toll on their physical and mental health. Acceptance and commitment therapy (ACT) is an empirically supported intervention that shows promise in improving binge eating, weight, and psychological functioning. This preliminary study evaluated the feasibility and acceptability of an 8-week ACT group intervention for binge eating in veterans (N = 85) who were overweight or obese and explored preliminary intervention effects on binge eating and physical and mental health functioning. Veterans were predominantly male (86.7%) with an average age of 58 years, and 65% endorsed clinically significant binge eating. Qualitative results indicated the majority of veterans found the intervention useful. Baseline to post-treatment comparisons found significant reductions in binge eating symptoms, depression, global psychological distress, and body mass index, as well as improvement in functioning. Findings suggest implementing ACT for binge eating in veterans is feasible and deserves further exploration, addressing binge eating and weight control. Future studies should examine ACT for this population in a randomized controlled trial.
