摘要：Personality traits can be used to predict an individual’s behaviors in different life situations, including marital life situations. Marital satisfaction that is influenced by different factors is a criterion used to assess couples’ relationship quality. The goal of the present study was to review Iranian studies on the correlation between personality traits and marital satisfaction. In this systematic review, all the related Iranian studies in international databases, including Google Scholar, PubMed, Web of Science (ISI) and Scopus, and national databases, including Scientific Information Database (SID) and MagIran were reviewed. The following keywords and also combinations of them were used to search the databases: “Marital satisfaction,” “Personality traits,” “Personality factors,” “Big five model of personality,” and “Iran.” A total of 18 correlational studies, without any time limitation, with a total sample of 4049, were reviewed. The following correlation coefficients were found between marital satisfaction and personality traits: r = − 0.439 with neuroticism (95% Confidence Interval [CI]: 0.27–0.60), r = 0.833 with extraversion (95% CI: 0.77–0.88), r = 0.777 with openness (95% CI: 0.70–0.84), r = 0.855 with agreeableness (95% CI: 0.80–0.90), and r = 0.90 with conscientiousness (95% CI: 0.84–0.95). Couples high in Neuroticism experience lower levels of marital satisfaction, and couples high in Conscientiousness are more satisfied with their marital life..
