Sibling support for transgender and nonbinary (TNB) youth has the potential to improve TNB youths' mental health. A scoping review was conducted to map the knowledge of TNB youths' sibling relationships to create a foundation for the development of sibling-based support interventions for TNB youth. Nine included articles covered two areas: TNB youths' perceptions of sibling support (n = 5) and cisgender siblings' lived experience with a TNB sibling (n = 4). Siblings were perceived to support TNB youth, and their support was associated with less depression, suicidal ideation, and externalizing problems. Siblings of TNB youth lacked knowledge of TNB identities and support for their own understanding and acceptance. Siblings may experience unique stressors around their TNB sibling's changing gender identity. Overall, having a TNB sibling was perceived as a positive experience. None of the studies included intervention with or for siblings of TNB youth. Sibling support can be helpful for TNB youths' mental health. However, cisgender siblings' unique needs are rarely addressed. Providing cisgender siblings with knowledge of TNB identity, a place to process fears and concerns, and skills to navigate situations that may arise in relation to their sibling's gender, has the potential to benefit both siblings.

对跨性别和性别多元化青年的兄弟姐妹支持：范围界定审查


对跨性别和非二元性别 (TNB) 青少年的兄弟姐妹支持有可能改善 TNB 青少年的心理健康。进行了范围界定审查，以绘制 TNB 青少年兄弟姐妹关系的知识，为 TNB 青少年制定基于兄弟姐妹的支持干预措施奠定基础。九篇纳入的文章涵盖两个领域：TNB 青少年对兄弟姐妹支持的看法 (n = 5) 和顺性别兄弟姐妹与 TNB 兄弟姐妹的生活经历 (n = 4)。人们认为兄弟姐妹支持 TNB 青少年，他们的支持与减少抑郁、自杀意念和外化问题有关。 TNB青年的兄弟姐妹缺乏对TNB身份的了解，也缺乏对自己理解和接受的支持。兄弟姐妹可能会因 TNB 兄弟姐妹不断变化的性别认同而经历独特的压力。总体而言，拥有 TNB 兄弟姐妹被认为是一种积极的经历。没有一项研究包括对 TNB 青少年的兄弟姐妹进行干预或为 TNB 青少年的兄弟姐妹进行干预。兄弟姐妹的支持有助于 TNB 青少年的心理健康。然而，顺性别兄弟姐妹的独特需求很少得到满足。为顺性别兄弟姐妹提供 TNB 身份知识、处理恐惧和担忧的场所以及应对可能出现的与兄弟姐妹性别相关的情况的技能，有可能使兄弟姐妹双方受益。
