Studies of gender development typically use binary, discrete measures of identity. However, growing literature indicates that some children might not identify with a binary gender. We tested a continuous measure of felt gender identity with gender-non-conforming children, socially transitioned transgender children, cisgender siblings, and unrelated cisgender children. In two studies, we found that transgender and cisgender children did not differ in their degree of identifying as their current gender, that they showed more binary identities compared with gender- non-conforming children, and that the continuum was a valid predictor of other measures of gender development. We also found that children's use of the continuous measure was stable over time. Our results demonstrate the test–retest reliability and validity of a new single-item continuous measure of gender.

男孩和女孩之间：在连续体上衡量性别认同

性别发展的研究通常使用二元的、离散的身份测量。然而，越来越多的文献表明，一些孩子可能不认同二元性别。我们对性别不一致的儿童、社会转型的跨性别儿童、顺性别兄弟姐妹和无关的顺性别儿童进行了连续的性别认同测量。在两项研究中，我们发现跨性别和顺性别儿童对当前性别的认同程度没有差异，与性别不一致的儿童相比，他们表现出更多的二元身份，并且连续体是其他指标的有效预测因子的性别发展。我们还发现，随着时间的推移，儿童对连续测量的使用是稳定的。我们的结果证明了新的单项连续性别测量的重测信度和效度。
