Objective: To test the reliability and validity of the 50-item Awareness of Age-related Change (AARC-50) Questionnaire among Chinese elderly people. Methods: AARC-50, the Personal Experience of Aging Scale (PEAS) and Philadelphia Geriatric Center Morale Scale(PGCMS) were applied to 960 individuals aged 60 years or older. Results: Exploratory factor analysis found that the revised questionnaire with 49 items presented a 2-factor model of the original English questionnaire, namely AARC-Gain and AARC-Loss, which contained 5 dimensions in respectively, explaining 73.26% of the total variation. Factor loadings of all 10 dimensions range from 0.79 to 0.89; Confirmatory factor analysis revealed that the two-factor model of AARC fits the data well （x²=130.11，df=32，x²/df=4.07，CFI=0.97，TLI=0.96, SRMR=0.05, RMSEA=0.08).The revised questionnaire had the good reliability: Cronbach's a coefficient was 0.86, specificly the positive valence (AARC-Gain) of the measure 0.91 and the negative valence (AARC-Loss) 0.90. the retest reliability of 56 elderly individuals was 0.84 over a 4-week period, meanwhile negative and positive valence dimensions having retest reliability of 0.93 and 0.94, respectively. The revised questionnaire was also proved to have good differentiation criterion validity and measurement invariance across gender. Conclusion: The revised questionnaire has good reliability and validity, and is suitable for measuring the subjective aging among elderly people in China.

目的：检验50条目的年龄变化觉知量表(Awareness of Age- related Change， AARC-50)在中国老年人中的信效度。方法：采用老年人年龄变化觉知量表、个人老化体验量表和费城老年中心信心量表对960名60岁及以上老年人进行施测。结果：探索性因子分析发现，含49个条目的修订后量表呈现了原量表的2因子模型，即增益因子和减损因子（各包含5个维度），解释总变异的73.26%的，10个维度的因子载荷均在 0.79～0.89之间；验证性因子分析显示其具有良好拟合度(χ~(2) =130.11，df=32，χ~(2)/df=4.07，CFI=0.97，TLI=0.96， SRMR=0.05， RMSEA=0.08)。修订后量表信度较好，Cronbach’s α系数为0.86，增益因子和减损因子的Cronbach’s α系数分别为0.91和0.90。四周后对56人的重测信度为0.84，增益因子和减损因子的重测信度分别为0.93和0.94。量表还被证实具有良好区分度、效标关联效度及跨性别的等值性。结论：修订后的量表具有较好的信效度，适用于中国老年人年龄变化觉知的测量。
