Measurement tools for gender identity, gender expression, and gender dysphoria in transgender and gender-diverse children and adolescents: a systematic review.

Increasing numbers of children and adolescents are being referred to gender services for gender-related concerns. Various instruments are used with these patients in clinical care, but their clinical validity, strengths, and limitations have not been systematically reviewed. In this systematic review, we searched MEDLINE, PubMed, and PsycINFO databases for available tools that assess gender identity, gender expression, or gender dysphoria in transgender and gender-diverse (TGD) children and adolescents.
