Reliability and validity of the Turkish version of the Self-care of Hypertension Inventory Version 3.0 in adults with hypertension

Abstract

Background: Hypertension is an important cardiovascular disease risk factor. Blood pressure control for hypertensive patients is crucial to prevent hypertension related complications. Ensuring and assessing self-care of hypertensive patients is important for blood pressure control and hypertension management. The Self-care of Hypertension Inventory (SC-HI) is an inventory developed for assessing self-care of hypertensive individuals. SC-HI has three subscales; maintenance, monitoring and management.

Objective: The aim of this study was to conduct Turkish version of SC-HI Version 3.0 (SC-HI V3.0) and assessing its psychometric properties for adults with hypertension.

Methods: We included 120 hypertensive patients in this methodological study. SC-HI V3.0 translated Turkish and tested for reliability and validity. To analyse structural validity item-total correlations and factor analyses was used. Intraclass correlation coefficient (ICC) method was selected for analysing scale's consistency and convergent validity was conducted.

Results: The mean age of participants were 54.74 ± 7.19 years and the mean duration from hypertension diagnosis were 38.19 ± 19.42 months. Translated Turkish version's factor loadings were ranged between 0.419 and 0.841. Cronbach's alpha coefficient values were 0.661, 0.880, 0.805 and ICC values were 1.0, 0.99, 0.99 for maintenance, monitoring and management, respectively. Convergent validity's correlation coefficients weak to very strong and statistically significant.

Conclusions: Turkish version of the SC-HI Version 3.0 is reliable, valid and useful scale for assessing self-management in hypertensive adults for clinical practice and research purposes.
