Assess understanding of core constructs and practical application of Self-Determination Theory (autonomy, competence, relatedness, intrinsic vs. extrinsic motivation) and the Transtheoretical Model (precontemplation to maintenance, processes of change, decisional balance, self-efficacy) for adult physical activity interventions. Test ability to compare theoretical assumptions, select stage-matched and need-supportive strategies, interpret case examples, choose appropriate measures, and discuss implications for intervention design, evaluation, and expected outcomes.
