Abstract
Background: Self-care plays a crucial role in managing hypertension (HTN). The Hypertension Self- Care Activity Level Effects (H-SCALE) is a comprehensive tool for assessing self-management behaviors in hypertensive patients. However, its validity and reliability have not yet been evaluated in Vietnam.
Objectives: This study aimed to assess the validity and reliability of the H-SCALE in evaluating self-care behaviors among hypertensive patients in primary care.
Methods: A cross-sectional study was conducted with 268 hypertensive patients. The reliability of the scale was assessed using Cronbach’s alpha. Exploratory Factor Analysis (EFA) was performed to determine the factor structure and evaluate convergent validity. Confirmatory Factor Analysis (CFA) was conducted to assess the model’s goodness-of-fit.
Results: The overall Cronbach’s alpha for the scale was 0.68, indicating an acceptable level of reliability. EFA identified five behavioral components: Medication Adherence, Physical Activity, Weight Management, Healthy Diet Compliance, and Smoking-Alcohol Consumption, with a total explained variance of 61.2%. CFA confirmed the five-factor model with good model fit (Chi-square/df = 1.70, p < 0.001, RMSEA = 0.05, GFI = 0.87, TLI = 0.90, CFI = 0.91, PCLOSE = 0.38).
Conclusions: The H-SCALE is a valid and reliable tool for assessing hypertension self-management behaviors in Vietnam. This instrument can assist healthcare providers in monitoring and counseling patients to improve their lifestyle behaviors, ultimately enhancing hypertension control.
