Comparison of Present Sample With Previous Reports of Population-Normed Internalizing Scores for children with GID24

Current Sample
(n = 73)
Toronto (n = 343) Utrecht (n = 123)
Mean age 7.7 y 7.2 y 8.1 y
Sample Transgendera GIDb GIDb
Measure of internalizing PROMISc CBCL CBCL
Mean internalizing t score 52.2 60.8 64.1

Both the PROMIS and CBCL are normed such that the population mean is t = 50 and SD is 10. CBCL, Child Behavior Checklist; PROMIS, Patient Reported Outcomes Measurement Information System.

The current participants were transgender, socially transitioned, and prepubescent.
