Development of a structural model of quality of life of heart patients based on the Center for Health Control and Disease Perception with the mediating role of mood dysphoria and cognitive flexibility

The aim of this study was to develop a structural model of quality of life of heart patients based on the Center for Health Control and Disease Perception with the mediating role of mood dysphoria and cognitive flexibility.

The method of this study was descriptive-correlation. The statistical population of the study included all heart patients referred to Shahid Rajaei Hospital, Tehran Heart Center and Khatam Al-Anbia Hospital in Tehran. A total of 281 patients were selected by convenience sampling and answered the Minnesota Quality of Life Questionnaire for Patients with Heart Failure, the Short Disease Perception Questionnaire, the Health Center Multidimensional Scale, the Cognitive Flexibility Questionnaire, and the Toronto Mood Dysfunction Scale.

Data analysis using structural equation modeling showed that the structural model of quality of life of heart patients based on health control and disease perception with the mediating role of mood dysphoria and cognitive flexibility fits. Also, there is a positive and significant relationship between health control center, disease perception and cognitive flexibility with quality of life (P <0.05), negative and significant relationship between mood distress and quality of life (P <0.05), between health control center and perception. Disease has a negative and significant relationship with quality of life (P <0.05) and there is a positive and significant relationship (P <0.05) between health control and disease perception with cognitive flexibility.

As a result, paying attention to the psychological dimensions and characteristics of patients with heart disease can bring a better understanding of this disease for patients and increase the quality of life.
