Commitment and its theorized determinants: A meta–analysis of the Investment Model

Le, Benjamin, Agnew, Christopher R.·2003·Personal Relationships

Abstract

We conducted a meta–analysis of Rusbult's Investment Model of commitment. Across 52 studies, including 60 independent samples and 11,582 participants, satisfaction with, alternatives to, and investments in a relationship each correlated significantly with commitment to that relationship. Moreover, these three variables collectively accounted for nearly two–thirds of the variance in commitment. Commitment, in turn, was found to be a significant predictor of relationship breakup. Support for the model was obtained in predicting commitment in both relational domains (e.g., commitment to a romantic partnership) and nonrelational domains (e.g., commitment to one's job), but was significantly stronger in relational domains. Additional moderator analyses suggested that the associations between commitment and its theorized bases vary minimally as a function of demographic (e.g., ethnicity) or relational (e.g., duration) factors. We review theoretical strengths and shortcomings of the Investment Model and identify directions for future research.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
