SHOULD I STAY OR SHOULD I GO - A DEPENDENCE MODEL OF BREAKUPS

A model of breakup decisions is proposed that extends interdependence theory. This dependence model asserts that the primary issue in understanding breakup decisions is degree of dependence on a relationship. Dependence is great when important outcomes in the current relationship are not available elsewhere. Need satisfaction dependence measures identify important needs in a relationship and compare satisfaction of those needs in the current relationship to satisfaction in alternative relationships. Two longitudinal studies provide good support for the dependence model. Need satisfaction dependence measures significantly differentiated between subjects who remained in their relationships and those who voluntarily broke up. The studies also compared the model to simpler breakup models and assessed whether commitment mediates the link between dependence and breakup decisions.
