Summary

The primary objectives of this randomized clinical trial are a) to implement and test the impact of a 1-year lifestyle obesity treatment program based on Self-Determination Theory on 3-year change in physical activity and motivation for exercise/physical activity, body weight and fat, and selected eating variables, b) to identify behavioral and psychosocial theory-based moderators or mediators of primary outcomes, especially physical activity and body weight.

Interventions

BEHAVIORAL

SDT and Motivational Interviewing in Obesity Treatment

Thirty group sessions, designed to follow SDT, covering PA, eating/nutrition, body image, and other cognitive-behavioral contents. Central to the intervention are improving autonomy, intrinsic motivation, and self-regulation of behavior change. Accepting ambivalence for change, rolling with resistance, and developing discrepancy were used throughout the program, with an emphasis on promoting intrinsic, self-regulated motivation for exercise and weight control.
