Assess learners' ability to design an evidence-based, culturally tailored community physical activity intervention for older adults with type 2 diabetes, requiring specification of target population and cultural adaptations; theoretical framework and behavior-change techniques (e.g., goal-setting, self-monitoring, MI); implementation plan (settings, partners, session format, accessibility); monitoring strategies (wearables, logs, clinical measures, adherence tracking); and an evaluation plan with process, outcome, and impact metrics (e.g., HbA1c, physical activity, function, QoL, cost-effectiveness), justified by guidelines and evidence.
