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.
We translated the CMSS into Persian and assessed its validity, reliability, and psychometric properties in Iranian patients with CVD.
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.
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).
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.
自我效能感在心血管疾病（CVD）的管理中起着重要作用。最初的心血管管理自我效能感量表（CMSS）是 2016 年在意大利 CVD 患者中开发的；然而，伊朗 CVD 患者中不存在这样的量表。
我们将 CMSS 翻译成波斯语，并评估其在伊朗 CVD 患者中的有效性、信度和心理测量特性。
这项研究于 2017 年在伊朗克尔曼沙阿的一家心血管医院进行了 4 个月，纳入了一组同意的 CVD 患者（N=363）。评估了波斯语 CMSS 的可靠性。我们使用一般自我效能感量表、医院焦虑抑郁量表和 36 项简短健康调查问卷评估了有效性，包括表面、内容、结构、收敛、发散和判别有效性。在高血压患者中评估了已知组的有效性。
波斯语 CMSS 具有可接受的表面和内容有效性。总量表没有发现地板或天花板效应。Cronbach α 计算为.68。通过组内相关系数（ICC1,3 = 0.98，P <.001）确认了测试-再测试的可靠性。通过探索性因子分析，确定了 3 个与原始版本相似的亚量表。波斯语 CMSS 与一般自我效能感量表（r = 0.94，P <.001）和医院焦虑抑郁量表（r = -0.35，P <.05）显著相关。使用波斯语 CMSS 测量的自我效能感在患者健康状况的 2 个水平之间存在统计学差异（P <.05）。高血压患者的自我效能感低于健康组（P <.05）。
CMSS 的波斯语版本为评估波斯语伊朗 CVD 患者临床管理中的自我效能感提供了一种实用、可靠和有效的量表。
