Mental Health during Medical Transition in a US and Canadian Sample of Early Socially Transitioned Transgender Youth.

Purpose: This study aimed to shed light on the mental health of a unique group of medically transitioning transgender adolescents: those who had made a binary social transition during childhood and who, in general, had not experienced substantial gender-incongruent puberty.

Methods: Study participants were part of a broader longitudinal study comprising 3 groups: transgender youth, their cisgender siblings, and unrelated cisgender peers. Using multilevel models, we compared self-reported and parent-reported levels of anxiety and depressive symptoms among transgender youth at 3 stages: before youth had begun puberty blockers; after they had begun blockers; and after they had begun hormone therapy. We also compared age-based mental health trajectories in transgender and cisgender youth.

Results: In this sample of transgender youth who sought and received gender-affirming medical care, participants experienced stable and relatively low levels of psychological distress across stages of medical transition and across time. There was one exception: transgender girls showed increased, followed by decreased, parent-reported depressive symptoms over time. In contrast, cisgender girls showed increases in internalizing symptomatology (with the exception of parent-reported anxiety) as they got older, and cisgender boys showed decreased self-reported anxiety and increased, followed by decreased, parent-reported depressive symptoms. By mid-adolescence, levels of anxiety and depressive symptoms among transgender girls and transgender boys generally fell between those of cisgender girls and cisgender boys.

Discussion: Results demonstrate that transgender youth who are socially and medically supported in their gender identity can experience stable and positive mental health throughout the notoriously challenging developmental period of adolescence.
