This study examined the hypothesis that gender identity and biological sex represent independent modules and that transgender individuals respond to romantic rivals in line with their gender identity and not with their biological sex. Additionally, associations of jealousy with intrasexual competitiveness (ISC) and social comparison orientation (SCO) were explored. A total of 134 male-to-female and 94 female-to-male transgender individuals from Greater Buenos Aires, Argentina, responded to a questionnaire. In line with the predictions, female-to-male transgender individuals experienced more jealousy than male-to-female transgender individuals in response to a physically dominant rival, whereas male-to-female individuals experienced more jealousy than female-to-male individuals in response to a physically attractive rival. Regardless of their gender identity, in both groups social-communal attributes were the most jealousy-evoking characteristic. Overall, the results indicate that transgender individuals mainly respond in line with their gender identity and not in line with their biological sex when facing romantic rivals. In addition, transgender individuals high in ISC experienced relatively more jealousy in response to all rival characteristics, whereas SCO was only among male-to-female individuals associated with jealousy.

当跨性别者面对浪漫的对手时，他们的反应是根据他们的生理性别还是他们的性别认同？

这项研究检验了这样的假设：性别认同和生物性别代表独立的模块，跨性别者根据他们的性别认同而不是他们的生物性别对浪漫对手做出反应。此外，还探讨了嫉妒与性内竞争力（ISC）和社会比较取向（SCO）的关联。来自阿根廷大布宜诺斯艾利斯的总共 134 名男变女和 94 名女变男跨性别者填写了一份调查问卷。与预测一致的是，女性对男性的变性人比男性对女性的变性人对身体上占主导地位的对手产生了更多的嫉妒，而男性对女性的变性人比女性对男性的变性人经历了更多的嫉妒。对外表有吸引力的对手的反应。无论性别认同如何，在这两个群体中，社会公共属性都是最容易引起嫉妒的特征。总体而言，结果表明，跨性别者在面对浪漫对手时，主要根据自己的性别认同做出反应，而不是根据自己的生理性别做出反应。此外，ISC 较高的跨性别个体对所有竞争特征的反应相对较多，而 SCO 只存在于与嫉妒相关的男性到女性个体中。
