Commitment Processes in Close Relationships: An Interdependence Analysis

TLDR

Interdependence theory explains why some relationships endure difficult times by distinguishing satisfaction and dependence, extending to the investment model that links higher satisfaction, poor alternatives, and resource investment to growing dependence and commitment. The investment model posits that dependence rises with higher satisfaction, perceived poor alternatives, and greater investment of important resources in the relationship. Strong commitment increases the likelihood of staying together and promotes maintenance behaviors such as adaptive social comparison, perceived superiority, derogation of alternatives, effective jealousy management, willingness to sacrifice, and accommodation rather than retaliation.

Abstract

This article employs interdependence theory as a means of understanding how and why some relationships survive difficult times whereas other promising relationships end. Interdependence theory makes important distinctions between satisfaction and dependence. These distinctions are extended in the investment model, a theory of the process by which individuals become dependent on and committed to their relationships. The investment model suggests that dependence increases not only as a consequence of increasing satisfaction, but also because available alternatives are perceived to be poor and numerous important resources are invested in a relationship. Subjective commitment summarizes the nature of an individual's dependence on a partner, and represents broad, long-term orientation toward a relationship. Strong commitment not only makes individuals more likely to remain with their partners, but also promotes a variety of relationship maintenance behaviors such as adaptive social comparison and perceived relationship superiority, derogation of attractive and threatening alternatives, effective management of jealousy and extrarelationship involvements, willingness to sacrifice for the good of a relationship, and tendencies to accommodate rather than retaliate when a partner behaves poorly.
