The Effectiveness of Acceptance and Commitment Therapy on Quality of Life in a Patient with Myocardial Infarction: A Randomized Control Trial

Objective: Acceptance and commitment therapy (ACT) interventions increase psychological flexibility and improve mental health and quality of life in patients with myocardial infarction. Study design: A controlled clinical trial study was conducted to evaluate the efficacy of an ACT intervention in improving the quality of life in patients with MI in Isfahan, Iran. Method: The present controlled clinical trial with a pre and post-test design was conducted on a statistical population consisting of patients with MI admitted to hospitals in Isfahan (n = 60) who were selected through sequential sampling based on the study inclusion criteria and were randomly divided into an intervention and a control group (n1 = n2 = 30). The case group received 8 weekly 90-minute sessions of ACT and the control group received no interventions. The pretest-posttest design was administered in both groups using a demographic questionnaire and the Minnesota Living with Heart Failure Questionnaire (MLHFQ) designed to assess the health status of patients with heart failure in terms of quality of life. The data obtained were analyzed in SPSS-20 using descriptive statistics and the ANCOVA. Results: In this study, 2 general areas of quality of life, including physical and mental health, were examined in the patients. There was a significant increase in the quality of life and subscales of mental and physical health in the experimental group (p < 0.001). Conclusion: Considering the effectiveness of ACT in improving quality of life in these patients, this method of intervention can be used as a complementary therapy in health care centers to reduce the side-effects experienced by these patients.
