Understanding the mechanisms underlying the effects of negative age stereotypes and perceived age discrimination on older adults' well-being.

Although numerous studies have documented that negative age stereotypes and perceived age discrimination are related to older adults' lower well-being, few studies have investigated the mechanisms underlying these relationships. In this study, we tested whether self-perceptions of aging and subjective age would help to account for the relation between stereotypes and discrimination and self-esteem. According to the internalization hypothesis, we expected that the effects of negative age stereotypes and greater perceived age discrimination would be driven by more negative self-perceptions of aging and older subjective age. A total of 151 older adults completed questions assessing their endorsement of negative age stereotypes, perceived age discrimination, self-perceptions of aging, subjective age, and self-esteem. Relationships among these variables were assessed using serial mediation analyses. Consistent with the internalization hypothesis, negative age stereotypes and perceived age discrimination indirectly predicted older subjective age and lower self-esteem through worsening self-perceptions of aging. However, we did not find a direct effect of negative age stereotypes or perceived discrimination on subjective age, nor an indirect effect of negative age stereotypes and perceived age discrimination on self-esteem through subjective age. These results support the internalization hypothesis: among older adults, holding more negative age stereotypes and perceiving more age discrimination is associated with feeling older and with lower self-esteem through worsened perceptions of one's own aging. Given the central role of self-perceptions of aging, these findings highlight the importance of promoting more positive self-perceptions in order to maintain or increase older adults' well-being.
