Abstract

Introduction: Self-care, behavior changes and health maintenance are the essential factors to prevent the exacerbation of cardiovascular disease. Having a valid and reliable tool is essential to evaluate self-care status of patients with hypertension. Relatively, the present study aimed to evaluate the psychometric properties of the Persian version of the Hypertension Self-Care Profile (HTN-SCP) in patients with high blood pressure. Materials and Methods: In this methodological research, using multi-stage cluster sampling, 325 patients with high blood pressure were selected to complete the Persian version of the hypertension self-care profile. The questionnaire was translated according to WHO guidelines. Face, content and construct validity (by exploratory and confirmatory factor analysis) was investigated. Reliability was measured using the McDonald's Omega and Cronbach's alpha coefficients. Results: Four factors, including diet and activity regimen, medication regimen, food labels and disease management were extracted based on exploratory factor analyses. They were able to explain 51.39% of the variance of all self-care variables. The fitness of the four-factor model of self-care construct was approved based on standard indices (NFI=0. 92, CFI=0. 96, PNFI=0. 80, RMSEA=0. 067). Reliability of HTN-SCP was 0.865 based on the Cronbach’s alpha coefficient. Conclusion: The four-factor structure of HTN-SCP suitable validity and reliability. Conclusively, given to its proper psychometric properties, this questionnaire can be used in patients with hypertension in future researches in Iran. © 2019, Semnan University of Medical Sciences.
