Identifying Specific Gaps in Knowledge of Aging and Examining Its Relation to Biases Toward Older Adults.

Abstract

Accurate aging knowledge is key to reducing ageist attitudes that impact older adult well-being. We first investigated how aging knowledge and negative and positive age-bias indirectly expressed via aging knowledge responses were related to an explicitly negative ageism measure. We then identified specific gaps in the aging knowledge of emerging adults and middle-aged adults. More negative ageism correlated with less aging knowledge overall and in psychological and social, but not biological, domains. Negative ageism correlated with negative age-bias, but not positive age-bias, expressed via aging knowledge responses. Knowledge of aging was poorest regarding social and psychological aspects of aging and best regarding biological aging. Middle-aged adults had slightly, but significantly, more accurate aging knowledge and less negative age-bias than emerging adults; positive age-bias did not differ by age-group. These results suggest that effectiveness of anti-ageism educational interventions may be enhanced if focused on improving knowledge of social and psychological aging.
