Abstract Public awareness of the diversity of experiences of gender identities has climbed sharply. The specific issues of those with gender dysphoria (GD) related to self-identity, body image, and medical interventions are challenges for the 21st century, particularly given the high risk of suicide. Gender identity is tightly linked to one’s bodily features, particularly readily observable sexual characteristics. For transgender and nonbinary individuals with GD, the incongruence between their body associated with their birth-assigned sex – what they see in the mirror before any treatment – and the internalized representation of their gender-identified body is a key defining part of their experience and contributes to their dysphoria. Currently, no clinical or research tool exists to capture and quantify the diverse experiences of one’s current body and one’s gender-identified body (which may be distinct from their current body), across a range of gender identities. Measuring the internalized representation of one’s body could be facilitated by technology to visually represent this on a three-dimensional avatar. The technology needed to scan and analyze the human figure is now available and cost efficient. It is now possible to scan individuals to create personalized 3D visualizations, or “avatars,” with which they can interact on mobile and desktop devices to represent internal representation of their bodies. This can allow individuals to see and manipulate their own 3D avatar with a high degree of flexibility. The goal of this project is to create a novel, visually based digital tool to measure, understand, and quantify individuals’ experiences of their bodies. We will develop, validate, and test in transgender, nonbinary, and cisgender adults a personalized avatar tool to represent internalized gender-identified bodies in order to quantify incongruence between this and one’s current body. This tool – “GD Somatomap” – will be an advancement over existing self-report questionnaires to capture visual representations of internalized body image, cross-sectionally and dynamically over time. It will be flexible enough to characterize the heterogenous experiences of a range of gender identities including binary transgender, gender fluid, nonbinary, and cisgender. It can be used in clinical and clinical research applications to track outcomes of cross-hormone and gender-affirming surgical treatments. It can potentially improve clinical outcomes by identifying specific sets of body parts as targets for treatments to improve body congruence. Further, it will provide a unique means to measure own-body perceptual accuracy; understanding differences in perceptual accuracy and what potentially modifiable factors contribute to this may have prognostic significance for treatments to address body incongruence. It could also be used in future studies to investigate functional and structural neurobiological correlates of body perception and internal body representation, and at what point in neurodevelopment these emerge for those with different gender identities.

抽象的 公众对性别认同经历多样性的认识急剧上升。具体问题 患有与自我认同、身体形象和医疗干预相关的性别不安 (GD) 的人是 21 世纪的挑战，特别是考虑到自杀风险很高。性别认同与性别认同紧密相关 一个人的身体特征，特别是容易观察到的性特征。对于跨性别者和非二元性别者 患有 GD 的人，他们的身体与其出生性别之间的不一致——他们是什么 在接受任何治疗之前先照照镜子——他们的性别认同身体的内化表征是 是他们经历的关键定义部分，并导致他们的烦躁不安。目前还没有临床或研究工具 存在的目的是捕捉和量化一个人当前身体和性别识别身体的不同体验 （可能与他们当前的身体不同），跨越一系列性别认同。测量内化 技术可以促进对一个人身体的表现，以在三维空间上直观地表现出这个身体 头像。扫描和分析人体所需的技术现已可用且具有成本效益。这是 现在可以扫描个人以创建个性化的 3D 可视化或“化身”，他们可以使用它 在移动和桌面设备上进行交互以代表他们身体的内部表现。这可以让 个人可以高度灵活地查看和操纵自己的 3D 化身。该项目的目标是 创建一种新颖的、基于视觉的数字工具来测量、理解和量化个人的体验 他们的身体。我们将在跨性别、非二元性别和顺性别成年人中开发、验证和测试个性化的 化身工具代表内在的性别识别机构，以量化这之间的不一致 以及现在的身体。该工具——“GD Somatomap”——将比现有的自我报告有所进步 问卷调查以横截面和动态方式捕捉内化身体形象的视觉表征 随着时间的推移。它将足够灵活地描述一系列性别的异质经历 身份包括二元跨性别者、流动性别、非二元性别和顺性别者。它可以用于临床和 跟踪跨激素和性别确认手术治疗结果的临床研究应用。它 通过确定特定的身体部位作为治疗目标，可以潜在地改善临床结果 提高身体一致性。此外，它将提供一种独特的方法来测量自己的身体感知准确性； 了解感知准确性的差异以及可能导致这种差异的潜在可改变因素 对于解决身体不一致的治疗具有预后意义。将来也可以使用 研究身体知觉和内部身体的功能和结构神经生物学相关性 代表性，以及在神经发育的哪个阶段，这些特征会出现在那些具有不同性别认同的人身上。
