Objective:The present study was designed to assess the construct validity and reliability of the Persian version of the 12-item Expectations Regarding Aging (ERA) survey among the older adult Iranian population. Methods: The Persian version of this scale was developed using translation and revision in the current study. The construct validity was assessed through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The reliability was assessed through internal consistency (Cronbach’s alpha and McDonald’s omega), composite reliability (CR), and maximal reliability (MaXR). The data compiled online was based on a sample of 400 older adults aged 65 years and older. Results: The Persian version includes 12 items loading onto three factors with 12 items explaining 46.633% of the total variance with excellent internal consistency and reliability. Conclusion: The Persian version of ERA is reliable and valid that can be used to assess the ERA concept among older adults.

目标：本研究旨在评估伊朗老年人口中 12 项关于老龄化 (ERA) 调查的波斯语版本的结构有效性和可靠性。方法：该量表的波斯语版本是在当前研究中使用翻译和修订开发的。通过探索性因素分析 (EFA) 和验证性因素分析 (CFA) 评估结构效度。可靠性通过内部一致性（Cronbach's alpha 和 McDonald's omega）、复合可靠性 (CR) 和最大可靠性 (MaXR) 进行评估。在线编制的数据基于 400 名 65 岁及以上老年人的样本。结果：波斯语版本包括加载到三个因素的 12 个项目，其中 12 个项目解释了总方差的 46.633%，具有出色的内部一致性和可靠性。结论：波斯语版本的 ERA 可靠且有效，可用于评估老年人的 ERA 概念。
