Abstract
This study examined factors that influence youth participation in heart disease prevention activities asmong 2,609 ninth graders in six inner-city public high schools. Constructs derived from social cognitive, empowerment, and community development theories informed the conceptual framework employed. Study participants were diverse with respect to gender, ethnicity, parent education, acculturation, and academic achievement. Perceived incentive value, self-efficacy, outcome expectancies, sense of community, and perceived policy control were all significantly associated with participation in community activities promoting heart health. In multivariate analyses, perceived incentive value, defined as the extent to which participants valued a heart-healthy environment, was most strongly associated with community participation, accounting for 11.9% of the total variance. These findings have implications for designing school curricula and after-school and community programs targeting adolescents' involvement in health advocacy activities.
