Older adults who are physically frail have poorer cognition compared to their robust peers. The mechanisms behind this association have yet to be established. Recent research has suggested that self-perceptions of aging are important predictors of physical and cognitive function in later life. This paper investigated whether self-perceptions of aging modify the relationship between frailty and cognitive function. 4135 participants from the Irish Longitudinal Study on Aging (TILDA) completed the Brief Aging Perceptions Questionnaire (B-APQ), a cognitive battery, and frailty measures. Frailty was associated with poorer cognition in participants with negative perceptions of aging but not in those without. There was a significant interaction between negative perceptions of aging and frailty in predicting global cognition (B = − 0.11, SE = .04) executive function (B = − 0.09, SE = .04) and attention (B = 0.13, SE = .04) but not memory (B = − 0.03, SE = .04). Negative perceptions of aging may modify the association between frailty and frontal cognitive domains in older adults.
