No previous research has examined the relationship between marital adjustment and similarity of partner personality on a measure of the five-factor personality model. The present study examined this relationship in 99 married couples. Spousal similarity on the domains of Conscientiousness, Agreeableness, Neuroticism, and several personality facets was related to marital adjustment. With the exception of Conscientiousness, the traits on which similarity was related to adjustment differed for husbands and wives. Reasons for these sex differences are discussed.
