The assessment of exercise self-efficacy in patients with cardiovascular disease (CVD) is necessary to conduct tailored interventions. The aim of the current study was to validate the Iranian version of the Cardiac Exercise Self-efficacy Scale (CESE) for patients with CVD.
To develop the Iranian version of the CESE scale, a forward and back translation procedure was followed. Data were collected from 260 patients with CVD who were admitted to Imam Ali Cardiovascular Hospital, Iran, using convenience sampling. Psychometric properties of the scale including validity (face and content validity, discriminant, concurrent, convergent, divergent, and construct validity) and reliability (internal consistency, and test-retest reliability) were assessed. SPSS software was used for statistical analysis.
The questionnaire had a good face and content validity and reliability, with Cronbach's alpha of 0.87 and intraclass correlation coefficient (ICC) of 0.42. The questionnaire discriminated well between subgroups according to their medical conditions and the "health transition" item in the Short-Form Health Survey (SF-36). There was a significant correlation between CESE and the physical components of the SF-36 (P < 0.001). In addition, a strong to moderate significant correlation was found between the CESE and the Exercise Self-efficacy Scale (ESES) (r = 0.77; P < 0.01) and between CESE and the Hospital Anxiety and Depression Scale (HADS) total (r = -0.45; P < 0.001). The exploratory factor analysis (EFA) identified a four-factor structure model, explaining 71.02% of the observed variance.
The Persian version of the CESE is a valid and reliable instrument for the evaluation of CVD patients' exercise self-efficacy level in performing regular exercise behaviors.
评估心血管疾病（CVD）患者的运动自我效能对于开展针对性干预措施很有必要。本研究的目的是验证用于CVD患者的伊朗版心脏运动自我效能量表（CESE）。
为编制伊朗版CESE量表，采用了正向和反向翻译程序。通过便利抽样，从伊朗伊玛目阿里心血管医院收治的260例CVD患者中收集数据。评估该量表的心理测量学特性，包括效度（表面效度和内容效度、区分效度、同时效度、收敛效度、发散效度和结构效度）和信度（内部一致性和重测信度）。使用SPSS软件进行统计分析。
该问卷具有良好的表面效度和内容效度以及信度，克朗巴哈系数为0.87，组内相关系数（ICC）为0.42。根据患者的病情以及简短健康调查问卷（SF-36）中的“健康转变”项目，该问卷在不同亚组之间具有良好的区分度。CESE与SF-36的身体成分之间存在显著相关性（P < 0.001）。此外，CESE与运动自我效能量表（ESES）之间存在强到中度的显著相关性（r = 0.77；P < 0.01），CESE与医院焦虑抑郁量表（HADS）总分之间也存在显著相关性（r = -0.45；P < 0.001）。探索性因子分析（EFA）确定了一个四因子结构模型，解释了71.02%的观察方差。
CESE的波斯语版本是评估CVD患者进行常规运动行为时运动自我效能水平的有效且可靠的工具。
