Previous research has demonstrated that men's lower mate value predicts increased perpetration of mate retention, especially with respect to cost inflicting behaviors. It is less clear if lower mate value women, including those who perceive themselves as being less physically attractive than their intrasexual rivals, also perpetrate more mate retention. Moreover, it is presently unclear whether romantic jealousy, which has been proposed to motivate compensatory behavior in response to evidence that a valued mating relationship is threatened, might mediate this link. The present study addressed this gap in knowledge by examining whether women's overall self-perceived mate value and upward physical appearance comparisons predicted their cost inflicting and benefit provisioning mate retention, as well as whether jealousy mediated these relationships. In a sample of 167 heterosexual undergraduate women, results found self-perceived mate value predicted greater benefit provisioning mate retention, but not romantic jealousy. In contrast, jealousy mediated the relationship between women's upward physical appearance comparisons and both their cost-inflicting and benefit-provisioning mate retention, supporting the hypothesis that jealousy in the face of unfavorable social comparisons on important mate value traits can promote action aimed at retaining a mate.
先前的研究表明，男性较低的配偶价值预示着他们更有可能实施配偶维持行为，尤其是在涉及施加成本的行为方面。然而，较低配偶价值的女性，包括那些认为自己不如同性竞争者有吸引力的女性，是否也更有可能实施配偶维持行为，这一点还不太清楚。此外，目前尚不清楚浪漫嫉妒感是否会在其中起到中介作用，因为这种嫉妒感被认为是为了应对有价值的恋爱关系受到威胁的证据而产生的补偿行为。本研究通过考察女性的整体自我感知的配偶价值和向上的外貌比较是否预测了她们的施加成本和提供利益的配偶维持行为，以及嫉妒感是否在这些关系中起到中介作用，来填补这一知识空白。在一个由 167 名异性恋本科女性组成的样本中，研究结果发现，自我感知的配偶价值预测了更大的提供利益的配偶维持行为，但不包括浪漫嫉妒感。相比之下，嫉妒感在女性向上的外貌比较与施加成本和提供利益的配偶维持行为之间起到了中介作用，支持了这样一种假设，即面对重要配偶价值特征的不利社会比较时，嫉妒感可以促进旨在留住伴侣的行为。
