Abstract

Abstract : Background: Self-efficacy plays a major role in the management of cardiovascular disease (CVD). The original Cardiovascular Management Self-efficacy Scale (CMSS) was developed in 2016 in Italian patients with CVD; however, no such scale exists for Iranian patients with CVD. Objective: We translated the CMSS into Persian and assessed its validity, reliability, and psychometric properties in Iranian patients with CVD. Methods: This study was conducted for 4 months in 2017 on a group of consenting patients with CVD (N = 363) recruited from a cardiovascular hospital in Kermanshah, Iran. The reliability of the Persian CMSS was evaluated. We assessed validity, including face, content, construct, convergent, divergent, and discriminate validity, using the General Self-efficacy Scale, the Hospital Anxiety and Depression Scale, and the 36-item Short Form Health Survey Scale. Known-group validity was assessed among patients with high blood pressure. Results: The Persian CMSS had acceptable face and content validity. No floor or ceiling effects were found for the total scale. Cronbach α was calculated as .68. Test-retest reliability was confirmed by intraclass correlation coefficient (ICC1, 3 = 0.98, P < .001). Using exploratory factor analysis, 3 subscales were identified, similar to the original version. Significant correlations were found between the Persian CMSS and both the General Self-efficacy Scale ( r = 0.94, P < .001) and Hospital Anxiety and Depression Scale ( r = −0.35, P < .05). Self-efficacy measured using the Persian CMSS was statistically different between 2 levels of patients' health status ( P < .05). Patients with hypertension had a lower level of self-efficacy than those in the healthy group ( P < .05). Conclusions: The Persian version of CMSS provides a practical, reliable, and valid scale for evaluating self-efficacy in the clinical management of Persian Iranian patients with CVD.
