Abstract
This article provides a systematic review and updated meta‐analysis of the extant literature on Rusbult's Investment Model of Commitment. This meta‐analysis aimed to determine the strength of the associations between commitment and its antecedents and to investigate potential moderators of these associations. This meta‐analysis included 50,427 participants from 202 independent samples (collected between 1980 and early 2016) that had examined the intercorrelations between satisfaction, investment size, quality of alternatives, and commitment. Across all studies, satisfaction had the largest aggregate association with commitment (r = 0.65), followed by investments (r = 0.53) and quality of alternatives (r = −0.43). Several significant moderators of the relationships between the antecedents and commitment were also identified. Implications and future research directions are discussed.
