Identification of significant predictors of physical activity in adolescents: by testing an integrated model of the theory of planned behavior that considers additional constructs such as habit, structural and environmental factors, past behavior, and self-discipline using structural equation modeling.

Identification of social cognition constructs (e.g., attitudes, risk perceptions, self-efficacy) that are correlated with individuals' intentions toward, and actual participation in, preventive behaviors towards minimizing respiratory infection transmission (e.g. hand washing, social distancing, vaccination for infections such as influenza, common cold, COVID-19): we will develop and test an integrated theoretical model that specifies the unique effects of each social cognition construct on intentions and preventive behavior participation, as well as identify moderators of these effects.
