    Abstract: BACKGROUND AND OBJECTIVES: This study examined the psychometric properties and measurement invariance of the 10-item Awareness of Age-Related Change Short Form (AARC-SF) questionnaire in a Chinese-speaking sample of older adults in Taiwan. RESEARCH DESIGN AND METHODS: Data from 292 participants (Mage = 77.64 years) in the Healthy Aging Longitudinal Study in Taiwan (HALST) cohort were used for Study 1, whereas data from young-old adult samples in Germany were used for Study 2. RESULTS: Study 1 showed that the AARC-SF had satisfactory reliability and validity for assessing adults' AARC in Taiwan. Analyses confirmed the two-factor structure of AARC-gains and AARC-losses. Study 2 demonstrated strong measurement invariance across men and women, whereas direct comparisons of the item scores between young-old adults and old-old adults need to be made with caution. Non-invariance of loadings indicated that certain items were more closely linked to AARC-gains and AARC-losses in Taiwan than in Germany. Non-invariance of intercepts suggested potential biases in comparing item scores between Taiwanese and German older adults. DISCUSSION AND IMPLICATIONS: The AARC-SF emerged as a reliable and valid instrument for capturing positive and negative subjective aging experiences among Taiwanese older adults. However, it is noteworthy that some items on the AARC-SF may solicit different responses from individuals of different ages and different countries of origin, requiring caution with age group and cross-cultural comparisons.
