Previous studies on health promotion in adolescents, using Pender’s HPM and social cognitive theory, have revealed that perceived benefits, perceived barriers, interpersonal influences (social support, social norms, and modeling) and perceived self-efficacy have an influence on physical activity. Of these, self-efficacy is the strongest predictor of physical activity among adolescents. Empirical evidence has shown that children and adolescents, who enjoy physical activity, are more likely to participate in physical activity.
