Purpose: The purpose of this study was to identify health care transition (HCT) readiness and skills among transgender youth transitioning gender-affirming care from pediatric to adult providers.Methods: A convenience sample of youth, 14-21 years old, their parents, and health care providers recruited from a multidisciplinary transgender youth clinic in 2019 completed a modified version of the Got Transition readiness assessment with elements specific to gender-affirming care. Youth assessed their own readiness, parents assessed their child's readiness, and providers assessed their transgender patients' readiness overall.Results: Twenty-nine youth (mean age 17.0 years), 26 parents, and 5 health care providers participated. Ratings of the overall importance of preparing for HCT were similar across all participant groups, and there were few disagreements on the importance of individual skills included in the readiness assessment. Ratings of overall HCT readiness were similar for youth regardless of age, while parents of younger youth (<18 years old) reported lower readiness than did parents of older youth. Youth rated their own competence in several skills higher compared with parents or providers, including knowledge of hormone therapy side effects. All groups of participants reported that youth most frequently needed assistance with scheduling appointments and keeping records of health information.Conclusions: Survey of youth, parents, and providers suggests that youth and parents require additional support to navigate the HCT process, highlighting the importance of ongoing skills assessment and planning.
