How do constraints on leaving a marriage affect behavior within the marriage?

Like relationship satisfaction, constraints on leaving a relationship have been described as a component of global commitment. But do constraints increase or decrease efforts to maintain the relationship? To address this question, the authors of the current article describe 3 independent studies of spouses and married couples. Across all studies, wives who perceived more constraints on leaving the marriage exhibited lower levels of negative behavior only when their husbands were relatively unconstrained. In Study 3, this association was especially pronounced among less satisfied wives. In Study 2, spouses' perceived constraint also interacted to predict husbands' behavior, but in the opposite direction: Husbands who perceived more constraints behaved less negatively when their wives were similarly constrained but more negatively when their wives were less constrained. These results highlight differences in behavior between couples who persist in marriage because they desire to and those who endure because they have to, raising questions about measures of global commitment that obscure these distinctions. They also highlight the need for a dyadic perspective on the forces that keep relationships together.
