A Longitudinal Study of Features Associated with Autism Spectrum in Clinic Referred, Gender Diverse Adolescents Accessing Puberty Suppression Treatment.

Literature has documented inflated rates of features associated with autism spectrum (AS) in clinic referred, gender diverse young people. This study examined scores on the Social Responsiveness Scale, Second Edition (SRS-2) over time in a group of clinic referred, gender diverse adolescents accessing gonadotropin-releasing hormone analogues (GnRHa) to supress puberty. Primary caregivers of 95 adolescents presenting to the Gender Identity Development Service (GIDS) completed the SRS-2 prior to receiving endocrine input (mean age: 13.6 ± SEM: 0.11) and after approximately one year of accessing GnRHa (mean age: 14.6 ± SEM: 0.13). No significant differences in SRS-2 scores over time and between birth assigned sex were found. No interactions between time and birth assigned sex were established for SRS-2 subscales or total scores.
