Mental Health Evaluation of Younger and Older Adolescents Referred to the Center of Expertise on Gender Dysphoria in Amsterdam, The Netherlands

Abstract

AbstractThe present study aimed to investigate whether differences exist between younger and older presenting adolescents at the Center of Expertise on Gender Dysphoria regarding psychological functioning and autistic traits. A total of 1487 consecutively assessed adolescents between 2000 and 2018 were divided in younger presenters (age ≤ 13.9 years) and older presenters (age ≥ 14 years). Of younger presenters, 227 (41.1%) were assigned male at birth and 325 (58.9%) assigned female at birth. In older presenters, 279 (29.8%) were assigned male at birth and 656 (70.2%) assigned female at birth. Behavioral and emotional problems were assessed with the Child Behavior Checklist (CBCL) and the Youth Self-Report (YSR). For autism traits, the Social Responsiveness Scale (SRS) was used. Compared to younger presenters, on both the CBCL and YSR older presenters had higher Total Problem (β = 1.75, p = .005, CI 0.53–2.97, R2 = .04 and β = 4.20, p < .001, CI 2.99–5.40, R2 = .07, respectively) and Internalizing Problem (β = 4.43, p < .001, CI 3.13–5.74, R2 = .06 and β = 6.69, p < .001, CI 5.31–8.07, R2 = .12, respectively) scores. Regarding autistic traits, a higher mean SRS total score was found in older presenting assigned males at birth (β = 4.55, p = .036, CI 0.30–8.81, R2 = .34). In assigned females at birth, no statistically significant difference between older and younger presenters was found in mean SRS total score (β = 1.19, p = .063, CI − 0.07 to 2.45, R2 = .39). Differences in mental health exist between younger and older presenting adolescents and call for an individualized approach in the clinical care of transgender adolescents.
