The impact of friendship structures on marital quality of heterosexual couples

Abstract

In this research, we considered how various structural aspects of friendship networks relate to marital quality according to gender. To investigate this issue, we drew on data from a large longitudinal survey on marital functioning based on 903 heterosexual couples living in Switzerland. Using reports from male and female partners, we explored the extent to which joint contacts, transitivity, and overlap in friendship structures affect various indicators of marital quality for husbands and wives in the long run. Our results indicate that separate, low transitive friendship networks affect marital quality negatively for women, but not for men. We also discuss the importance of the results for understanding the dynamics of heterosexual couples within larger relational contexts beyond dyadic interactions, as well as the relevance of separately analyzing husbands' and wives' marital dynamics.
