: A reasonable assessment of the self-perception of aging (SPA) is of great significance to the health outcomes of older adults. This study aimed to develop the Modified Aging Perception Questionnaire (M-APQ) and to verify its psychometric properties. : A multi-method study was conducted. In phase I, a qualitative study was conducted to supplement items to form the draft M-APQ. In phase II, three rounds of cognitive interviews were conducted to revise ambiguous items and form the prefinal M-APQ. In phase III, items were selected using Classical Test Theory (CTT) and Item Response Theory (IRT) to form the final M-APQ. In phase IV, the psychometric properties of the final version of M-APQ were validated. : Three items were added in Phase I. Six items were revised in Phase II. Eleven items were removed in phase III, leaving twenty-four items in the final version of M-APQ. In phase IV, the M-APQ showed good construct validity and convergent validity. The known-group validity analysis indicated significant differences in the M-APQ dimension scores on different self-rated health statuses. The Cronbach's α for M-APQ and each dimension ranged from 0.798 to 0.888, and the intraclass correlation coefficients ranged from 0.704 to 0.883. The IRT analysis showed that item discrimination parameters ranged from 1.746 to 3.630, and difficulty parameters increased sequentially. : The 24-item M-APQ includes seven dimensions and is a valid tool for assessing the self-perception of aging (SPA) among community-dwelling older adults.
对衰老自我认知（SPA）进行合理评估对老年人的健康状况具有重要意义。本研究旨在开发改良衰老认知问卷（M-APQ）并验证其心理测量学特性。
开展了一项多方法研究。在第一阶段，进行了一项定性研究以补充项目，形成M-APQ草案。在第二阶段，进行了三轮认知访谈以修订模糊项目，形成预终版M-APQ。在第三阶段，使用经典测验理论（CTT）和项目反应理论（IRT）选择项目，形成最终版M-APQ。在第四阶段，对最终版M-APQ的心理测量学特性进行了验证。
在第一阶段增加了3个项目。在第二阶段修订了6个项目。在第三阶段删除了11个项目，最终版M-APQ保留24个项目。在第四阶段，M-APQ显示出良好的结构效度和收敛效度。已知组效度分析表明，不同自评健康状况下M-APQ维度得分存在显著差异。M-APQ及其各维度的克朗巴赫α系数在0.798至0.888之间，组内相关系数在0.704至0.883之间。IRT分析表明，项目区分参数在1.746至3.630之间，难度参数依次增加。
24项M-APQ包括七个维度，是评估社区居住老年人衰老自我认知（SPA）的有效工具。
