Development of the Persian hypertension self-management questionnaire

Abstract

Background: Hypertension results in severe health problems and intensifies the risk of stroke, heart and kidney diseases, and death. Having a valid and reliable questionnaire for self-management of hypertension is very important. Objectives: This study aimed to evaluate the psychometric properties of the Persian hypertension self-management questionnaire. Methods: This psychometric exploratory research was conducted in Tabriz in 2017. In this exploratory research, the Persian version of diabetic patients’ self-management questionnaire, which had proper psychometric properties, was modified in order to assess hypertensive patients’ self-management. The face and content validity of the Persian hypertension self-management questionnaire was evaluated. Content Validity Ratio (CVR), Content Validity Index (CVI), and Impact Score (IS) of the questionnaire were calculated by participation of 49 hypertensive patients and 14 experts. Cronbach’s alpha coefficient and Intra-class Correlation Coefficient (ICC) were considered to assess the reliability of the questionnaire. Results: The questionnaire’s overall CVI, CVR, and IS were 0.82, 0.63, and 4.41, respectively. Additionally, the CVIs of all questions were over 0.62. Moreover, the internal consistency of the questionnaire was approved by Cronbach’s alpha = 0.882 and its ICC was 0.94. Conclusion: The study findings revealed that the Persian hypertension self-management questionnaire had optimal psychometric properties. Hence, application of this questionnaire by physicians and health educators can be helpful in establishing evidence-based self-management support programs for hypertensive patients.
