Endorsement of existence values predicts mate retention behaviors

Abstract

People deploy mate retention behaviors to thwart a long-term romantic partner's infidelity. Cost-Inflicting mate retention behaviors (e.g., inducing a partner's jealousy) are riskier than Benefit-Provisioning mate retention behaviors (e.g., showing love and care for a partner), because the former increase the odds of a partner's defection or retaliation. Individual differences in endorsement of Existence values—i.e., valuing Personal Stability, Health, and Survival—may be associated with the type of mate retention behaviors people perform. We hypothesized that individuals who endorse Existence values more (versus less), would perform less frequent Cost-Inflicting mate retention behaviors (controlling for performance of Benefit-Provisioning mate retention behaviors; Hypothesis 1), and more frequent Benefit-Provisioning mate retention behaviors (controlling for performance of Cost-Inflicting mate retention behaviors; Hypothesis 2). Participants (n=164), each in a heterosexual, romantic relationship of at least three months duration, completed a survey that included the Mate Retention Inventory-Short Form and the Basic Values Survey. Endorsement of Existence values was negatively associated with performance of Cost-Inflicting mate retention behaviors (supporting Hypothesis 1), and positively associated with performance of Benefit-Provisioning mate retention behaviors (supporting Hypothesis 2). We situate these results within an evolutionary framework on mate retention, and discuss their theoretical and applied utility.
