Gender differences in the relationship between perceived discrimination and personality traits in young adulthood: Evidence using sibling fixed effects.

Rationale: Although perceived discrimination (PD) is known to be associated with personality traits, family background characteristics may confound this association. Moreover, little is known about whether the relationship differs by gender.

Objective: This study investigates whether the association between PD and personality traits is confounded by family background characteristics. Given gender differences in contexts and perceptions of discrimination as well as personality traits, this study also explores whether the association between PD and personality traits differs for men and women.

Methods: Using data from the National Longitudinal Study of Adolescent to Adult Health, this study examines the association between PD and Big Five personality traits among young adults. This study uses sibling fixed effects models with a lagged dependent variable to account for unobservable family-level characteristics, such as genetics, parental characteristics, family environment, and childhood social contexts.

Results: Sibling fixed effects estimates showed that PD was associated with lower levels of conscientiousness and extraversion and higher levels of neuroticism. There were also gender differences such that PD was associated with lower conscientiousness only for women and lower extraversion only for men. The positive association with neuroticism was apparent for both men and women.

Conclusion: This study suggests that the association between PD and personality traits is generally not confounded by stable family-level characteristics shared by siblings. This study also documents gender differences in the relationship between PD and personality traits. Given substantial implications of personality for a broad range of outcomes, especially among young adults, the findings of this study reaffirm the commitment of the whole society to eradicate any form of discrimination.
