Social networks, structural interdependence, and marital quality over the transition to marriage: a prospective analysis.

This study examined the relationship between couples' network interdependence and marital quality in a sample of 347 couples that were recruited at the time of their first marriage. Husbands and wives completed separate, self-administered questionnaires at home. Analyses are based on data collected at the time of marriage, at the first anniversary, and at the second anniversary. Results indicated that after marriage, husbands' and wives' friend and family networks became increasingly interdependent. Moreover, the interdependence of the friend and family networks at marriage predicted wives' marital quality at the first anniversary, whereas wives' marital quality at the first anniversary predicted the interdependence of the friend network at the second anniversary. No significant longitudinal relations were observed for husbands.
