Abstract
The present study examined the association between personality similarity and life satisfaction in a large, nationally representative sample of 1608 romantic couples. Similarity effects were computed for the Big Five personality traits as well as for personality profiles with global and differentiated indices of similarity. Results showed substantial actor and partner effects, indicating that both partners' personality traits were related to both partners' life satisfaction. Personality similarity, however, was not related to either partner's life satisfaction. We emphasize the importance of thoroughly controlling for each partner's personality and for applying appropriate analytical methods for dyadic data when assessing the effect of personality similarity in couples.
