In college and adult samples, women score higher then men on the Five Factor Model (FFM) personality traits of Neuroticism and Agreeableness. The present study assessed the extent to which these gender differences held in a sample of 486 older adults, ranging in age from 65-98 (M = 75, SD = 6.5), using the NEO-Five Factor Inventory. Mean and Covariance Structure models testing gender differences at the level of latent traits revealed higher levels of Neuroticism (d = .52) and Agreeableness (d = .35) in older women than older men. The consistency of these findings with prior work in younger samples attests to the stability of gender differentiation on Neuroticism and Agreeableness across the lifespan. Gender differences on these traits should be considered in personality research among older, as well as middle age and younger adults.
KeywordsGender Differences; Personality Traits; Older Adults; Five Factor Model Women score higher on the Five Factor Model (FFM) traits of Neuroticism and Agreeableness (Costa, Terracciano & McCrae 2001). The former reflects distress proneness and propensities toward the experience of a variety of negative affects, while the latter reflects amicability, altruism, trust, tendermindedness, and compliance. Gender differences on these traits are of medium magnitude: Costa and colleague's comprehensive study showed US adult women scored .51 SD higher on Neuroticism and .59 SD higher on Agreeableness. Costa et al. replicated this pattern of gender differences across 26 different nations in data comprising over 23,000 individuals. These findings cannot easily be attributed to self-report artifacts, as McCrae and colleagues (2005) have replicated them in observer reports of FFM traits across 50 cultures. Goodwin and Gotlib (2004) replicated the Neuroticism and Agreeableness findings in a nationally representative sample using a brief trait-adjective measure of the lexical Big Five (cf. also Goldberg et al., 1998), suggesting these gender differences are not a sole function of
