Human appearance enhancement effort has recently been considered from an evolutionary perspective as an adaptive and sexually dimorphic strategy for effective female intrasexual and intersexual competition. Most writing and research on the topic to date has focused on appearance enhancement as a means of mate attraction, with relatively less research examining its role in mate retention. The present study considered whether romantic jealousy, as a negative emotion experienced in response to perceived threat to a desired relationship, predicts costly and/or risky appearance enhancement independent of the closely related emotion of envy. In a sample of 189 undergraduate women, results showed that romantic jealousy and dispositional envy were positively correlated with one another. Results further demonstrated that romantic jealousy predicted women's positive attitude toward cosmetic surgery, willingness to use a one-week free tanning membership, willingness to use a risky diet pill, and intent on spending a greater proportion of their income on appearance enhancement, but not intended use of facial cosmetics. Results held independent of participants' dispositional envy, suggesting that romantic jealousy is a unique predictor of women's efforts at enhancing their physical appearance, which could extend into costly and physically risky mate retention efforts.
人类的外貌提升行为最近从进化的角度被认为是一种适应性的、性别二态的策略，旨在有效地进行女性内群体和外群体竞争。迄今为止，大多数关于该主题的写作和研究都集中在外表吸引力上，即作为吸引伴侣的一种手段，而相对较少的研究关注其在伴侣维系中的作用。本研究探讨了浪漫嫉妒（一种对一段渴望的关系受到威胁的负面情绪）是否可以预测代价高昂和/或高风险的外貌提升，而不是考虑到与浪漫嫉妒密切相关的嫉妒情绪。在一个由 189 名本科女性组成的样本中，结果表明浪漫嫉妒和性格上的嫉妒彼此之间呈正相关。结果进一步表明，浪漫嫉妒可以预测女性对整容手术的积极态度、使用一周免费晒黑会员资格的意愿、使用高风险减肥药的意愿、以及将更大比例的收入用于外貌提升的意愿，但不包括使用面部化妆品的意图。研究结果独立于参与者的性格嫉妒，表明浪漫嫉妒是女性努力提升外貌的独特预测指标，这可能会延伸到代价高昂和身体风险高的伴侣维系努力中。
