Daily ageism and negative affect as a function of older adults’ sexual orientation.

= 59.73, range = 50-79) completed measures of daily ageism as indicated by ageist messages, experiences of age-based discrimination, internalization of ageist beliefs, and NA over 14 consecutive days. Results showed that participants reported higher daily NA on days when they experienced higher levels of ageism. The daily association between ageist messages and the internalization of ageist beliefs (both descriptive and prescriptive) and NA was stronger among older adults belonging to sexual minorities compared to their heterosexual counterparts. No such interaction was found for experiences of age-based discrimination. Investigating daily fluctuations in ageism and well-being among older adults from diverse sexual orientation groups is essential, as it captures the context-dependent and recurring nature of age-related stigma in everyday life. From an applied perspective, this research helps identify daily vulnerabilities in well-being faced by an understudied sexual minority population, namely, older sexual minority adults. It underscores the importance for practitioners to recognize these day-to-day challenges and consider timely, context-sensitive interventions to support their well-being.
