The effectiveness of mindfulness-based intervention on perceived stress and perception of disease in patients with acute coronary syndrome

Abstract

Context: One of the most important issues in patients with coronary artery disease is their mental health indices such as perceived stress and perception of disease. Aims: The aim of this study was to evaluate the effectiveness of mindfulness-based intervention on the perceived stress and disease perception of patients with acute coronary syndrome. Materials and Methods: This is a clinical trial, two-group, and three-stage study on 76 patients with acute coronary syndrome who were randomly divided into intervention and control groups. Nine weekly sessions of mindfulness-based training program were administered to the intervention group. The control group received routine services during this period. Data collection was done before, immediately, and 1 month after the intervention, using the Perceived Stress Scale and the Illness Perception Questionnaire. Data were analyzed using descriptive and inferential statistics. Results: There was no significant difference between the mean scores of perceived stress and illness perception before intervention. After the intervention and 1 month after it, the mean score of perceived stress in the intervention group was statistically significantly lower than the control group (P < 0.001), and the perception of disease in the intervention group was statistically significantly higher than that of the control group (P < 0.001). Conclusions: It is worthwhile to suggest the mindfulness-based training program to reduce the perceived stress and correct the perception of disease for patients with acute coronary syndrome.
