BACKGROUND Population aging is an important phenomenon for many countries worldwide. Considering the growing trend of aging population in Iran, it is very important to consider beliefs and perceptions of old people about aging. The Aging Perception Questionnaire (APQ) is one of the most common instruments that used to measure aging comprehension. The present study was a methodological inquiry that aimed to examine validity and reliability of the Persian version of the Aging Perception Questionnaire (APQ). METHODS Forward-backward procedure was used for translation. Content validity and face validity were evaluated qualitatively. In order to evaluate construct validity a cross section study was conducted and both exploratory and confirmatory factor analyses were performed. In order to determine reliability, internal consistency (the Cronbach's alpha) and stability (Intraclass Correlation Coefficient -ICC) were estimated. RESULTS A total of 500 elderly people attending the community centers in Tehran, Iran were entered in other study and completed the Persian version of the questionnaire. Most elderly were female (52.8%).The mean age of participants was 68.33 (SD ± 6.10) years. The results obtained from exploratory factor analysis showed a four-factors solution (consequences negative, emotional representation, control positive and consequences positive) that jointly explained 52.8% of the total variance observed. In addition the confirmatory factory analysis showed a good fit for the data. Finally, the Cronbach's alpha coefficient of 0.83 ranging from 0.80 to 0.87 was obtained for the whole scale and the subscales. The ICC value of 0.96 ranging from 0.90 to 0.98 was found for the whole scale and the subscales. CONCLUSION The results indicated that the Persian version of APQ is valid and can be used to measure aging perception in Iran.

波斯简写的《老龄感知问卷》（APQ-P）：一项验证研究。

背景技术人口老龄化是全世界许多国家的重要现象。考虑到伊朗人口老龄化的趋势，考虑老年人对老龄化的看法和看法非常重要。衰老感知问卷（APQ）是用于衡量衰老理解力的最常见工具之一。本研究是一种方法学探究，旨在检查波斯语版《老龄感知问卷》（APQ）的有效性和可靠性。方法采用向前-向后程序进行翻译。定性评估内容有效性和面部有效性。为了评估构建体有效性，进行了横断面研究，并进行了探索性和确认性因素分析。为了确定可靠性，内部一致性（Cronbach' 估计值和稳定性（类内相关系数-ICC）。结果总共有500名参加伊朗德黑兰社区中心活动的老年人参加了另一项研究，并填写了波斯语问卷。大多数老年人为女性（52.8％）。参与者的平均年龄为68.33（SD±6.10）岁。从探索性因素分析获得的结果显示出四因素解决方案（后果为负，情绪表征，控制积极和后果为积极）共同解释了观察到的总方差的52.8％。此外，工厂验证性分析表明该数据非常合适。最后，对于整个量表和子量表，Cronbach的α系数为0.83到0.80至0.87。ICC值为0.96，范围从0.90到0。在整个量表和子量表中发现98个。结论结果表明，APQ的波斯版本是有效的，可用于测量伊朗的老龄化感知。
