Validation of a Chinese Version of the Self-Efficacy for Managing Chronic Disease 6-Item Scale in Patients with Hypertension in Primary Care

Abstract

The aim of this study was to validate a Chinese version of the Self-Efficacy for Managing Chronic Disease 6-Item Scale (SES6C). In 2012, a cross-sectional study was conducted in a community clinic, in Beijing, China. A total of 262 hypertension patients participated in this study. Concurrent validity was validated by Pearson’s correlations between the SES6C and Hospital Anxiety and Depression Scale (HADS). Intraclass correlation coefficients (ICC) were performed to evaluate test-retest reliability of the scale. Related factors of self-efficacy were explored in linear regression models. The results of our study display acceptable psychometric properties: the scale was two-dimensional, reproducible (ICC = 0.78; 95% CI, 0.70–0.84), and the reliability was good (Cronbach’s alpha = 0.88). Significant ( r = - 0.30 ; P < 0.001 ) correlation was found between the level of self-efficacy and the level of psychological distress. In multivariable analysis, the factors significantly associated with self-efficacy were regular exercise ( β = 0.659 , P < 0.01 ), HADS total score ( β = - 0.076 , P < 0.001 ) and health status ( β = - 0.530 , P < 0.001 ). The study provides evidence that the SES6C is acceptable, valid and repeatable for hypertension patients.
