Objective: The purpose of the present study was to explore the relations between temperament and character dimensions of personality and marital satisfaction. Methods: More specifically, the present study investigated the relationship between the Temperament and Character Inventory and the Dyadic Adjustment Scale in a sample of 55 married couples. Results: The temperament scale reward dependence correlated significantly with the satis-faction, consensus of opinion, and marital adjustment scores. The temperament scale persistence correlated significantly with the attachment score. The temperament scale harm avoidance negatively correlated significantly with the attachment score. The character scale cooperativeness correlated significantly with the satisfaction score. Conclusion: High reward dependence is probably a basic factor in marital satisfaction.
