The aim of this study was to translate and evaluate the validity and reliability of the Impact of Events Scale-Revised (IES-R) among the Iranian general population during the coronavirus disease 2019 (COVID-19) pandemic. This study was methodological cross-sectional. It was conducted on an Iranian public population from April to July 2020 which was during the COVID-19 pandemic. Construct validity was determined through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) with a total of 500 adults recruited online data gathering. Reliability was checked through the average inter-item correlation (AIC), Cronbach's alpha, and McDonald's omega. Convergent and divergent validity was determined using Fornell and Larcker's approach. The results showed that the Persian version of IES-R had three factors, including intrusion (six items), avoidance (seven items), and hyperarousal (five items), that explained 59.22% of the total variance of the IES-R. The CFA findings indicated that all goodness-of-fit indices confirmed the model fit. The Cronbach's alpha, McDonald's omega, composite reliability (CR), and maximal reliability were excellent, and the three factors have good convergent validity. The findings of this study indicated that the Persian version of the IES-R scale is efficient and useful to assess post-traumatic stress disorder among Iran general population in the COVID-19 outbreak.
本研究的目的是翻译并评估事件影响量表修订版（IES-R）在2019年冠状病毒病（COVID-19）大流行期间伊朗普通人群中的有效性和可靠性。本研究为方法学横断面研究。于2020年4月至7月在COVID-19大流行期间对伊朗公众进行。通过探索性因子分析（EFA）和验证性因子分析（CFA）确定结构效度，共招募500名成年人进行在线数据收集。通过平均项目间相关性（AIC）、克朗巴哈α系数和麦克唐纳ω系数检查信度。使用福尔内尔和拉克尔的方法确定收敛效度和区分效度。结果表明，IES-R的波斯语版本有三个因子，包括侵入（6个项目）、回避（7个项目）和过度唤醒（5个项目），解释了IES-R总方差的59.22%。CFA结果表明，所有拟合优度指标均证实模型拟合良好。克朗巴哈α系数、麦克唐纳ω系数、组合信度（CR）和最大信度都非常好，这三个因子具有良好的收敛效度。本研究结果表明，IES-R量表的波斯语版本在评估COVID-19疫情期间伊朗普通人群的创伤后应激障碍方面是有效且有用的。
