The effects of a transtheoretical model-based exercise stage-matched intervention on exercise behavior in patients with coronary heart disease: A randomized controlled trial

摘要

Objective: To determine whether a transtheoretical model-based exercise stage-matched intervention (ESMI) has positive effects on the exercise behavior of sedentary patients with coronary heart disease (CHD). Methods: The study was a randomized controlled trial with a repeated measures design. Participants (N= 196) were randomly allocated to either a conventional (C) group, a patient education (PE) group, or an ESMI group. Exercise behavior was measured by exercise stages of change, exercise self-efficacy, exercise decisional balance, and duration of moderate exercise at baseline, immediate post-intervention, and at 3- and 6-month follow-up. Results: Our results showed that the ESMI group demonstrated a more positive shift in exercise stages of change (p< 0.01), higher exercise self-efficacy (p< 0.01), greater exercise benefits (p< 0.01), fewer exercise barriers (p< 0.01), and longer moderate exercise duration (minutes/week) (p< 0.01) after completion of the 8-week intervention compared with the C and PE groups. These significantly positive effects were maintained at 3- and 6-month follow-up. Conclusion: The transtheoretical model-based ESMI had significantly positive effects on the exercise behavior of sedentary CHD patients. Practice implications: It is important to provide a structured education program for CHD patients, preferably guided by the transtheoretical model.
