Marriage improves neuroticism in Chinese newlyweds: Communication and marital affect as mediators.

We examined the mediating roles of communication and marital affect in the association between marital quality and neuroticism. Guided by the social investment theory and the personality-relationship transactions model, we tested the actor-partner interdependence mediation model to examine the associations among the variables. Participants were 268 Chinese newlywed couples who were a maximum of 3 years into their first marriage. The path model indicated that, first, both spouses' marital quality at Time 1 was related with their own neuroticism at Time 3 after controlling for confounding variables. However, after controlling for neuroticism at Time 1, husbands' marital quality was not directly associated with their own neuroticism. Second, for wives, communication and marital affect at Time 2 fully mediated the association between marital quality and neuroticism. Conversely, for husbands, the multiple specific indirect effects were not significant. These findings suggest that communication and marital affect are mediators underlying the association between marital quality and neuroticism. Moreover, the potential mechanisms underlying the relationship effects differ between husbands and wives. The implications and future directions of these results were discussed.
