Test graduate-level understanding of core constructs from three major behavior change models used in physical activity promotion—Transtheoretical Model (stages of change, processes of change, decisional balance, self-efficacy), Social Cognitive Theory (self-efficacy, outcome expectations, observational learning, reciprocal determinism), and Theory of Planned Behavior (attitudes, subjective norms, perceived behavioral control, intentions)—including concise definitions and the ability to match each construct to simple intervention strategies or examples in physical activity contexts.
