| description | Background and Aim: Hypertension is the strongest independent and modifiable factor for heart failure, ischemic heart disease, cerebrovascular accident and chronic kidney disease worldwide, which affects the quality of life of patients. In order to accurately assess the quality of life of patients, it is necessary to design a special questionnaire consisting of different dimensions in order to provide a good view of the quality of life of these patients. The purpose of this study is “Design and psychometrics of quality of life tools for patients with hypertension.”
Materials and Methods: The present study is a methodological research that was conducted in qualitative and quantitative parts. Participants in this study were 260 patients with hypertension referring to medical centers affiliated to Tehran University of Medical Sciences (TUMS). The items were designed based on the qualitative part of the study and review of texts. The validation characteristics of the questionnaire were performed using face validity, content (qualitatively and quantitatively using two indicators CVR and CVI) and structure (with exploratory factor analysis approach). The reliability of the questionnaire was assessed by internal consistency and stability methods.
Results: In the qualitative section, 55 items were extracted, which after calculating the item impact score index with values higher than 1.5, content validity ratio greater than 0.56 and content validity index higher than 0.57, 45 items were selected. Using heuristic factor analysis, 42 items and three factors: 1) disease dominance including two subscales of physical (7 items) and psychosocial (20 items), 2) coping with the disease (12 items) and 3) compliance with Drug therapy (3 items) was found to jointly account for 53.30% of the observed variance. Cronbach’s alpha reported the internal reliability of the questionnaire as excellent, at 91%.
Conclusion: The designed questionnaire has appropriate and approved psychometric properties (validity and reliability) to measure the quality of life of patients with hypertension. Therefore, this tool is recommended for measuring the variables in Iranian patients with hypertension. |
