Abstract
BACKGROUND: Hypertension (HTN) is a public concern and treatment adherence has a key role in its management. This study was conducted to develop and test the reliability and validity of the Hypertensive Treatment Adherence scale (HTA-scale). METHODS: This was a cross-sectional and methodological study. After item generation using a qualitative study and literature review, the scale was developed. The psychometric properties of the scale were evaluated using face, content, construct, and criterion validity and reliability. RESULTS: Data analysis showed that the HTA-scale had acceptable face and content validity. The scale had excellent stability Intraclass correlation coefficient (ICC) = 0.74 and good acceptability and internal consistency (Cronbach's = 0.76). Exploratory factor analysis (EFA) showed that the HTA-scale consisted of 6 meaningful subscales including medication adherence and monitoring, adherence to safe diets, avoiding unsafe diets, self-medication, activity, and smoking. Participants in the controlled blood pressure group had significantly higher HTA-scale scores than the uncontrolled blood pressure group. At the cut-off point of 86, the scale had significant sensitivity and specificity. CONCLUSION: All of the psychometric properties of the HTA-scale achieved the standard level and were sufficient to recommend this scale for patients with HTN. © 2020, Isfahan University of Medical Sciences(IUMS).
