Interventions

  • ITHBC-Based Sedentary Behavior Intervention — BEHAVIORAL
    The intervention is a 1-month nurse-delivered sedentary behavior intervention based on the Integrated Theory of Health Behavior Change (ITHBC). It addresses three core components of ITHBC: knowledge and beliefs, self-regulation skills and abilities, and social facilitation. Intervention strategies include health education related to sedentary behavior and coronary heart disease, individualized goal setting, self-monitoring, action planning, feedback, and professional and family/social support to facilitate reduction of sedentary behavior and promote physical activity. After the 1-month intervention period, participants will receive a 2-month follow-up to support maintenance of behavior change.

Study Details

This study aims to evaluate the feasibility and effectiveness of a sedentary behavior intervention based on the Integrated Theory of Health Behavior Change (ITHBC) in older adults with coronary heart disease and frailty. Participants will be randomly assigned to an intervention group or a control group. The intervention is designed around the three core components of ITHBC-knowledge and beliefs, self-regulation skills and abilities, and social facilitation-to help participants reduce sedentary behavior, improve physical activity, and enhance their ability to manage health-related behaviors. The study will include a 1-month intervention period followed by a 2-month follow-up period, with a total study duration of 3 months for each participant. Changes in sedentary behavior and other health-related outcomes will be assessed throughout the study period.

Arms

  • Experimental: ITHBC-Based Sedentary Behavior Intervention
    Participants in this arm will receive a 1-month sedentary behavior intervention based on the Integrated Theory of Health Behavior Change (ITHBC), in addition to usual care. The intervention incorporates strategies targeting knowledge and beliefs, self-regulation skills and abilities, and social facilitation. Participants will subsequently be followed for 2 months, resulting in a total study duration of 3 months.
  • No Intervention: Usual Care
    Participants in this arm will receive usual care provided by the clinical team and will not receive the ITHBC-based sedentary behavior intervention. Participants will be followed for the same 3-month study period as the intervention group.
