N2 - Objective: Excess weight has been associated with numerous psychological problems, including depression and anxiety. This study examined the impact of intentional weight loss on the psychological well-being of adults participating in three clinical weight loss interventions. Methods: This population consisted of 588 overweight or obese individuals randomized into one of three weight loss interventions of incremental intensity for 12 months. Psychological well-being was measured at baseline and 6, and 12 months using the Psychological Well-Being Index. Results: Mean weight loss was 5.0 pounds at 12 months. Weight change at 12 months was associated with higher overall psychological well-being (r = -.20, p <. 001), lower levels of anxiety (r = -.16, p =. 001) and depression (r = -.13, p =. 004), and higher positive well-being (r = -.19, p <. 001), self-control (r = -.13, p =. 004), and vitality (r = -.22, p <. 001). Vitality was found to be the best predictor of weight change at 12 months (p <. 001). Conclusions: Weight loss was associated with positive changes in psychological well-being. Increased vitality contributed the largest percentage of variance to this change.
