Project Health: Enhancing Effectiveness of a Dissonance-Based Obesity Prevention Program

This project seeks to improve the effectiveness of a novel dissonance-based obesity prevention program that has reduced future BMI gain and overweight/obesity onset by (a) experimentally testing whether implementing it in single- versus mixed-sex groups, which should increase dissonance-induction that contributes to weight gain prevention effects, and (b) experimentally testing whether adding food response and attention training, which theoretically reduces valuation of and attention for high-calorie foods, increases weight gain prevention effects. This randomized trial would be the first to experimentally manipulate these two factors in an effort to produce superior weight gain prevention effects. A brief effective obesity prevention program that can be easily, inexpensively, and broadly implemented to late adolescents at risk for excess weight gain, as has been the case with another dissonance-based prevention program, could markedly reduce the prevalence of obesity and associated morbidity and mortality.
