Personality and functional impairment. Evidence from the Survey of Health, Ageing and Retirement in Europe

Abstract

Background: To date, only a few studies have investigated the association between personality and functional impairment. Therefore, our purpose was to add to this knowledge. Methods: Data from wave 7 of the Survey of Health, Ageing and Retirement in Europe (SHARE) were used (70 028 individuals in the analytical sample). Personality was measured using the 10-item Big Five Inventory (BFI-10). Functional impairment was quantified using activities of daily living (ADL) and instrumental activities of daily living (IADL) indices. Multiple linear regressions were conducted. Results: Regressions showed that an increased likelihood of limitations in ADL was associated with higher extraversion, higher agreeableness, lower conscientiousness, higher neuroticism, and higher openness to experience. Similarly, an increased likelihood of limitations in IADL was associated with higher agreeableness, lower conscientiousness, higher neuroticism, and higher openness to experience (only with one IADL index). Conclusions: This knowledge of associations between personality and functional limitations may help in determining individuals at risk for increased functional impairment (e.g., individuals with low conscientiousness or high neuroticism). Future research is needed to clarify the underlying mechanisms.
