Abstract

Despite considerable clinical interest, attempts to link perceived self-efficacy with successful weight control have had mixed success. Definitive data on prospective associations between self-efficacy and weight loss are particularly sparse. This study examined relationships between self-efficacy beliefs, weight control behaviors, and weight change among individuals participating in a weight loss trial (N = 349, 87% women). Cross-sectionally, eating and exercise self-efficacy beliefs were strongly associated with corresponding weight loss behaviors. Self-efficacy beliefs prospectively predicted weight control behavior and weight change during active treatment but not during follow-up. Mediational models indicate that people's weight control behaviors mediate the impact of self-efficacy on weight change.
