title: Determinants of physical activity among Taiwanese adolescents: an application of the health promotion model.
abstract: The purpose of this study was to examine the relationships among interpersonal influences (i.e., social support, norms, modeling), behavior-specific cognitions (i.e., self-efficacy, perceived benefits/barriers), competing demands, and physical activity among Taiwanese adolescents (N = 832). The results from structural equation modeling indicated that perceived self-efficacy was the most important predictor of physical activity. Interpersonal influences, when considered in total, had a weak and nonsignificant direct effect on physical activity but had indirect effects on physical activity thorough perceived benefits and perceived self-efficacy. When sources of interpersonal influences were considered separately, parental influences did not have direct effects on physical activity. In contrast, peers did have a significant direct effect on physical activity and also indirect influences on physical activity through perceived self-efficacy. All variables accounted for 30% of the variance in physical activity. Results of this study identify important influences useful to health professionals for promoting physical activity in this population.
