Abstract Objectives The established link between subjective views of aging (VoA) and well-being shows variations across different cultures. Although VoA show daily fluctuations, little is known about cultural differences in such fluctuations and the daily coupling of VoA and well-being. We compared Israeli Arabs to Israeli Jews in the daily coupling of VoA and negative affect (NA). Methods Community-dwelling older adults (N=76, Mage=66.71) completed measures of subjective age, subjective accelerated aging, ageist attitudes, and NA over 14 consecutive days. Results Respondents reported higher daily NA when they felt older, reported to be aging faster, or had more ageist attitudes. The daily coupling between subjective age/subjective accelerated aging and NA was stronger among Israeli Arabs compared to Israeli Jews. There was no such interaction with ageist attitudes. Discussion It is important to adopt a cultural perspective when investigating daily fluctuations in VoA and their correlates. In applied contexts, this might help to identify cultural groups that are particularly sensitive to the effects of VoA.
