Abstract
OBJECTIVES: Prior studies of age-restricted samples have demonstrated that, in older adulthood, neuroticism is negatively associated with difficulties performing specific daily activities. No studies of neuroticism and physical functioning have been conducted on life-span samples. This study tested the hypothesis that the relationship between neuroticism and physical functioning is stronger in older people compared with younger and middle-aged adults. METHOD: Data were obtained from 2 independent French samples (n = 1,132 and 1,661 for Samples 1 and 2, respectively) ranging in age from 18 to 97. In addition to reporting sociodemographics, participants completed the Big Five Inventory, the physical functioning scale of the 36-Item Short Form Health Survey, and measures of disease burden. RESULTS: In both samples, regression analysis indicated that neuroticism is more negatively associated with physical functioning with advancing age, controlling for gender, marital status, disease burden, and educational attainment. DISCUSSION: In life-span samples of more than 2,700 adults, neuroticism was more strongly associated with worse physical functioning among older people compared with younger and middle-aged adults. Longitudinal research is needed to confirm this finding and to identify potential mediators.
