Role of Personality Traits in Predicting Newlywed Intimacy and Relationship Quality

While personality traits can predict couples' behaviors in marital life, there are limited studies on the relationship between personality and marital relationships. This study aimed to examine the role of personality in predicting intimacy and the quality of marital relationships in newlywed couples. This cross-sectional study included 115 newlywed couples who participated in an online survey. Participants completed three questionnaires: the NEO Personality Inventory for assessing personality traits, the Intimacy Safety Questionnaire (ISQ) for measuring marital intimacy, and the Quality of Marriage Index (QMI) for evaluating marital quality. Marital intimacy was positively predicted by extraversion and conscientiousness in women and extraversion, conscientiousness, and openness in men. Relationship quality was negatively predicted by neuroticism in women while positively predicted by openness, agreeableness, and conscientiousness in men.
