Abstract. Personality has been found to play an important role in predicting satisfaction in couples. This review presents dyadic research on the association between Big Five traits and both life and relationship satisfaction in couples focusing on self-reported personality, partner-perceived personality (how the partner rates one’s own personality), and personality similarity. Furthermore, special attention is given to possible gender effects. The findings indicate the importance of self-reported as well as partner-perceived reported personality for the satisfaction of both partners. Specifically, the majority of studies found intrapersonal and interpersonal effects for neuroticism, agreeableness, and conscientiousness on life or relationship satisfaction. For the partner-perceived personality, intrapersonal and interpersonal effects were present for all Big Five traits. Partners’ similarity in personality traits seems not to be related with their satisfaction when controlling for partners’ personality.
