Developing a theory-based intervention to enhance physical activity in older adults with atrial fibrillation and frailty: a behavior change wheel approach

The BCW provides a systematic approach to designing behavioral change interventions that can improve physical activity, delay frailty in older patients with AF, and reduce healthcare burdens. Our findings indicate that interventions should focus on enhancing disease knowledge, teaching physical activity skills, providing social support, and using appropriate BCTs in older patients with AF and frailty. Our next step will be to conduct a feasibility study to assess the acceptability and effectiveness of these intervention programs.
