Mate value discrepancies and mate retention behaviors: A cubic response surface analysis

Abstract

AbstractThis study used cubic polynomial regression with response surface analysis to examine the associations that mate value discrepancies (i.e., the difference between an individual's self‐reported mate value and their perceptions of their partner's mate value) had with mate retention behaviors performed by the individual and their perceptions of the mate retention behaviors performed by their partner. The sample included 1083 undergraduates, and the results revealed a congruence effect such that participants who perceived themselves and their romantic partners to have similarly low levels of mate value reported high levels of cost‐inflicting behaviors by themselves and their partners. There was also a curvilinear association that emerged for mate value discrepancies such that individuals who perceived themselves to have higher levels of mate value than their partners reported higher levels of cost‐inflicting behaviors by themselves and their romantic partners. These results demonstrate how cubic response surface analysis can allow for a better understanding of the connections that mate value discrepancies have with outcomes in romantic relationships.
