Assess graduate learners' ability to analyze and compare major behavior-change theories (e.g., Social Cognitive Theory, Transtheoretical Model, Self-Determination Theory, Health Belief Model) and evidence-based interventions (e.g., motivational interviewing, goal-setting, action planning, mHealth, supervised exercise) used to promote long-term physical activity adherence in adults with chronic conditions; evaluate theoretical mechanisms, strengths and limitations, contextual moderators, measurement of adherence, evidence quality, and provide recommendations for scalable, sustainable program design and future research.
