Evaluation of Extended Model of Health Related Quality of Life in Patients with Coronary Artery Disease

Quality of life compared to health or illness has a special position for policymakers and health-care specialists. The goal of this study was to evaluate the expanded model of health-related quality of life in patients with coronary artery disease.

This is a descriptive correlational study that is based on structural equation modeling. The statistical population includes all patients with coronary artery disease who referred to Tehran and Karaj medical centers and received a diagnosis by a specialist. 650 persons were selected by available sampling method and responded to Illness Perception Questionnaire, Quality of Life Questionnaire, Self-Care of Heart Failure Index, Emotional Well-being Scale, Psychological Well-being Questionnaire of Reef, Social Well-being Questionnaire of Keyesand Seattle Angina Questionnaire.

The results of this study showed that the developed model of Wilson has a good fit. That is, by adding self-management and psychological, social, and emotional well-being, this model can be adopted to explain the quality of life. However, compared to the original model of well-being indices, due to the multidimensionality and the multiple relationships, it should be considered as a comprehensive well-being construct. Self-management can also explain comprehensive well-being.

Self-management and positive indicators of well-being can have a special role in the process of health-related quality of life in patients with coronary artery disease.
