Pilot Trial of a Telephone Weight Loss, Nutrition, Exercise Study

Completed · Not applicable

Conditions studied: Weight Loss, Weight, Body

In brief

Many behavioral weight loss interventions have been developed, but still have significant limitations in terms of achieving clinically significant, sustained weight loss. A recent study incorporating Acceptance and Commitment Therapy (ACT) in a randomized clinical trial resulted in participants who attained significantly greater 12-month weight loss in the ACT arm than those assigned to standard behavioral treatment, suggesting that ACT may have the potential to improve behavioral weight loss outcomes. The investigators have developed a novel telephone-delivered version of the ACT behavioral weight loss intervention, based on proven success using ACT telephone counseling intervention for smoking cessation.
