Abstract：
UNASSIGNED: Measuring socioeconomic status (SES) as an independent variable is challenging, especially in epidemiological and social studies. This issue is more critical in large-scale studies on the national level. The present study aimed to extensively evaluate the validity and reliability of the Iranian SES questionnaire.
UNASSIGNED: This psychometric, cross-sectional study was conducted on 3000 households, selected via random cluster sampling from various areas in East Azerbaijan province and Tehran, Iran. Moreover, 250 students from Tabriz University of Medical Sciences were selected as interviewers to collect data from 40 districts in Iran. The construct validity and internal consistency of the SES questionnaire were assessed using exploratory and confirmatory factor analyses and the Cronbach\'s alpha. Data analysis was performed in SPSS and AMOS.
UNASSIGNED: The complete Iranian version of the SES questionnaire consists of 5 factors. The Cronbach\'s alpha was calculated to be 0.79, 0.94, 0.66, 0.69, and 0.48 for the occupation, self-evaluation of economic capacity, house and furniture, wealth, and health expenditure, respectively. In addition, the confirmatory factor analysis results indicated the data\'s compatibility with the 5-factor model (comparative fit index = 0.96; goodness of fit index = 0.95; incremental fit index = 0.96; root mean square error of approximation = 0.05).
UNASSIGNED: According to the results, the confirmed validity and reliability of the tool indicated that the Iranian version of the SES questionnaire could be utilized with the same structure on an extensive level and could be applicable for measuring the SES in a broader range of populations.

摘要：
■将社会经济地位（SES）作为自变量进行测量具有挑战性，尤其是在流行病学和社会研究中。这个问题在国家一级的大规模研究中更为关键。本研究旨在广泛评估伊朗SES问卷的有效性和可靠性。
■这种心理测量学，对3000户家庭进行了横断面研究，通过随机整群抽样从东阿塞拜疆省和德黑兰的不同地区选出，伊朗。此外，来自大不里士医科大学的250名学生被选为采访员，从伊朗40个地区收集数据。使用探索性和验证性因素分析以及Cronbachα评估SES问卷的结构效度和内部一致性。数据分析采用SPSS和AMOS。
■完整的伊朗版本的SES问卷由5个因素组成。Cronbach的α值计算为0.79、0.94、0.66、0.69和0.48，经济能力的自我评估，房子和家具,财富,和卫生支出，分别。此外,验证性因素分析结果表明数据与5因素模型（比较拟合指数=0.96；拟合优度指数=0.95；增量拟合指数=0.96；近似均方根误差=0.05）的相容性。
■根据结果，该工具的确证的有效性和可靠性表明,伊朗版本的SES问卷可以广泛使用相同的结构,并且可以适用于更广泛人群的SES测量.
