Assess graduate-level understanding of core constructs and mechanisms of Social Cognitive Theory (e.g., self-efficacy, outcome expectancies, observational learning), Theory of Planned Behavior (attitudes, subjective norms, perceived behavioral control, intention), and the Transtheoretical Model (stages of change, processes, decisional balance) as applied to promoting physical activity in adults; require definition of constructs, comparison of overlaps and divergences, explanation of causal mechanisms, and concise application by critiquing or designing brief interventions and measurement strategies, noting strengths, limitations, and evaluation metrics.
