The Five-Factor Model of personality and relationship satisfaction of intimate partners: A meta-analysis

A meta-analysis that included 19 samples with a total of 3848 participants showed that scores on four of the Five-Factor Model personality factors correlated significantly with level of relationship satisfaction by intimate heterosexual partners. The four personality characteristics were low neuroticism, high agreeableness, high conscientiousness, and high extraversion. The associations between an individual’s personality characteristics and the relationship satisfaction of the individual’s intimate partner did not vary significantly from men to women or from married to unmarried individuals. The results of the meta-analysis provide support for the utility of the Five-Factor Model of personality in understanding an important realm of life, intimate relationships.
