Purpose: Because obesity has not responded well to instructing affected adults in healthier eating behaviors and increased physical activity/exercise, enhanced research on psychosocial determinants of those behavioral changes is needed. Intervention foci on self-regulation have been suggested, but targeted research is required. Method: Women with obesity participated in community-based treatments that were either self-regulation-focused (self-regulation emphasis group; n = 52) or typical instruction-based (education [treatment-as-usual] group; n = 54). Results: There were overall significant increases in exercise-related self-regulation, physical activity/exercise, exercise-related self-efficacy, and eating-related self-regulation that were each significantly more pronounced in the self-regulation emphasis group. Increase in exercise-related self-regulation over 3 months predicted eating-related self-regulation over 6 months; however, sequential entry of changes in physical activity and exercise-related self-efficacy significantly mediated that relationship. However, only the path from changes in exercise-related self-regulation to exercise self-efficacy to eating-related self-regulation was significant. In a revised model where change in exercise self-efficacy was the sole mediator, treatment group did not significantly moderate the exercise self-regulation to eating self-regulation change relationship, but full mediation of that relationship occurred. Conclusion: Findings indicated salience for perceived ability/self-efficacy for physical activity, over actual physical activity progress, and its role in the transfer of self-regulatory skills from an exercise to eating context. Increased eating self-regulation significantly predicted weight loss over 6, 12, and 24 months. In the self-regulation emphasis group that translated to meaningful weight loss/weight-loss maintenance of greater than 5% of initial weight. Findings contributed to an increased understanding of psychosocial-change processes within obesity treatment research.
