From game theory to real life: How social value orientation affects willingness to sacrifice in ongoing close relationships

This research adopted an interdependence analysis of sacrifice, examining the link between commitment (i.e., the subjective experience of dependence and long-term orientation) and willingness to sacrifice in ongoing close relationships, and determining whether this link is moderated by preexisting individual differences in social value orientation (i.e., prosocial, individualistic, or competitive orientation). Consistent with hypotheses, results of 2 studies revealed both that willingness to sacrifice was associated with greater commitment and that this link was more pronounced among individualists than among prosocials. Results also revealed an association between one's own willingness to sacrifice and beliefs regarding the partner's willingness to sacrifice (this link was somewhat more pronounced among prosocials than among individualists) and one's own willingness to sacrifice and actual partner's willingness to sacrifice.
