Rusbult’s Investment Model of Commitment Processes is one of the most well-known and influential theoretical frameworks in the area of close relationships. This model explains how committed partners maintain and promote their relationships by transforming personal motives to take into account the necessity of coordinating and getting along with partners.

Rusbult served as an Associate Editor for the Journal of Personality and Social Psychology (1990 to 1994) and the Encyclopedia of Psychology (1996 to 2000), and was elected to the boards of several national and international organizations (e.g., Society of Experimental Social Psychologists, International Society for the Study of Personal Relationships).

The Caryl E. Rusbult Young Investigator Award has been created in her memory.
