ObjectiveSexual and gender minority (SGM) people are underrepresented in psychological research. Part of the underrepresentation of SGM people likely stems from potential participants' unwillingness to join a study, but more concerningly, researchers exclude data from SGM participants. Furthermore, much of SGM research focuses on existing health disparities and risk factors rather than wellness‐framed and personality research. To fill in this gap, the current study aims to quantify effect sizes of similarities/differences across a broad range of psychosocial measures.MethodApplying the framework of the Gender Similarities Hypothesis, we compare means, variances, and correlations across 34 psychosocial variables between categories of SGM, gender identity, sexual orientation, relationship status, and monogamy (N = 1743). Data was collected online mainly through paid ads on Instagram.ResultsConsistently, we find largely similarities across gender identity, sexual orientation, and relationship structure categories. These results support a general expectation that similarities are more common than differences in normative psychological domains, although clear differences in means and variances exist for specific experiences and outcomes.ConclusionsThis work informs the inclusion of diverse identities in basic psychological research and further speaks to the generalizability of past findings to populations historically underrepresented in psychological science.

与其他人不同，但我们是相同的：不同性和性别认同的社会心理变量比较


目的性少数群体和性别少数群体 （SGM） 在心理学研究中代表性不足。SGM 人员代表性不足的部分原因可能是潜在参与者不愿意参加研究，但更令人担忧的是，研究人员排除了 SGM 参与者的数据。此外，SGM 的大部分研究都集中在现有的健康差异和风险因素上，而不是以健康为框架和个性的研究。为了填补这一空白，目前的研究旨在量化广泛的社会心理测量中相似/不同之处的效应大小。方法应用性别相似性假说的框架，我们比较了 SGM、性别认同、性取向、关系状况和一夫一妻制 （N = 1743） 类别之间 34 个社会心理变量的均值、方差和相关性。结果结果一致，我们发现性别认同、性取向和关系结构类别之间有很大相似之处。这些结果支持了一个普遍的预期，即在规范心理学领域中，相似性比差异更常见，尽管特定经历和结果在均值和方差上存在明显的差异。结论这项工作为在基础心理学研究中纳入不同身份提供了信息，并进一步说明了过去的发现对历史上在心理科学中代表性不足的人群的普遍性。
