Thinking about commitment: Accessibility of commitment and prediction of relationship persistence, accommodation, and willingness to sacrifice

Research has demonstrated that more accessible cognitive constructs (e.g., attitudes, stereotypes) are more likely to influence thoughts and behaviors. The current research applies a social cognition framework to the prediction of romantic relationship persistence (i.e., "stay-leave" behavior), accommodation, and willingness to sacrifice. Conceptualizing commitment as a partially cognitive construct and following from social cognition and attitudinal research, we hypothesized that the accessibility of commitment will moderate the association between commitment and relationship persistence, accommodative responses, and willingness to sacrifice. In Study 1, participants in romantic relationships responded to statements derived from the commitment subscale of the Investment Model Scale. Reaction times to these statements were used as a measure of accessibility of commitment. In addition, participants completed measures of their commitment level. Seven months later, participants were contacted and relationship persistence was assessed. Accessibility of commitment significantly moderated the association between commitment and relationship persistence. Study 2 expanded on the results of the first study by demonstrating that accessibility of commitment also significantly moderated the association between commitment and accommodation and willingness to sacrifice. Taken together, these two studies highlight the usefulness of applying social cognitive concepts to understand close relationships.
