This study aimed to assess the psychometric properties of the Farsi version of the Electroconvulsive Therapy-Related Anxiety Questionnaire (ERAQ).
This methodological study was conducted among patients undergoing or with a history of Electro Convulsive Therapy (ECT) in Mashhad, Iran, during 2024-2025. Data were collected using a demographic profile form and the ERAQ. The questionnaire was translated into Farsi using the forward-backward translation method, and its face and content validity were assessed both qualitatively and quantitatively. To evaluate construct validity, exploratory factor analysis (n = 150) and confirmatory factor analysis (n = 150) were performed. Convergent validity was examined using Composite Reliability and Average Variance Extracted values, while discriminant validity was assessed through the Heterotrait-Monotrait ratio. Reliability was determined by estimating internal consistency through Cronbach's alpha and McDonald's omega coefficients.
During exploratory factor analysis, item 9 was removed because its factor loading was less than 0.30, and the remaining 16 items were distributed across three factors: life disruption, socio-physical disruption, and memory disruption, which collectively explained 45% of the total variance. Confirmatory factor analysis demonstrated a good fit for the proposed model. All composite reliability, maximum reliability, and heterotrait-monotrait ratios supported the convergent and discriminant validity of the ERAQ. Additionally, Cronbach's alpha and McDonald's omega coefficients confirmed the acceptable internal consistency of the Farsi version of the ERAQ.
Based on the findings of this study, the Farsi version of the ERAQ demonstrates sufficient validity and reliability to assess anxiety symptoms associated with ECT in the Iranian population.
本研究旨在评估波斯语版电休克治疗相关焦虑问卷（ERAQ）的心理测量特性。
本方法学研究于2024年至2025年期间在伊朗马什哈德接受电休克治疗（ECT）或有ECT病史的患者中进行。使用人口统计学资料表和ERAQ收集数据。问卷采用前后翻译法翻译成波斯语，并对其表面效度和内容效度进行了定性和定量评估。为了评估结构效度，进行了探索性因子分析（n = 150）和验证性因子分析（n = 150）。使用组合信度和提取的平均方差值检验收敛效度，同时通过异质特质-同质特质比率评估区分效度。通过Cronbach's alpha和McDonald's omega系数估计内部一致性来确定信度。
在探索性因子分析中，第9项因因子载荷小于0.30而被删除，其余16项分布在三个因子上：生活干扰、社会-身体干扰和记忆干扰，这三个因子共同解释了总方差的45%。验证性因子分析表明所提出的模型拟合良好。所有组合信度、最大信度和异质特质-同质特质比率均支持ERAQ的收敛效度和区分效度。此外，Cronbach's alpha和McDonald's omega系数证实了波斯语版ERAQ具有可接受的内部一致性。
基于本研究结果，波斯语版ERAQ在评估伊朗人群中与ECT相关的焦虑症状方面具有足够的效度和信度。
