Self-Reported Multidimensional Gender Identity in Autistic and Non-Autistic Children

PURPOSE: The several prior studies assessing gender identity in young autistic individuals mostly included a mix of child and adolescent participants, heavily relied on parent-reported measures, and yielded mixed findings. A single parent-reported item from the Child Behavior Checklist assessing "wish to be of the opposite sex" was employed in most of these studies. Only one prior study focused specifically on children, but that study employed parent-reported measures.

Using self-reported multidimensional measures, the present study assessed gender identity in autistic and non-autistic children aged 4 to 11 years (30 autistic boys, 35 non-autistic boys, 20 autistic girls, 35 non-autistic girls). Child-friendly measures were used to assess own-gender similarity, other-gender similarity, gender contentedness, and wish to be of the other gender. Vocabulary and non-verbal reasoning were also assessed.

Based on descriptive statistics, compared with non-autistic boys, autistic boys showed increased gender identity variance across all four dimensions (lower own-gender similarity, higher other-gender similarity, lower gender contentedness, greater wish to be of the other gender). These group differences between autistic and non-autistic boys were medium and statistically significant for three of the four dimensions and small-to-medium and marginally significant for the remaining dimension. Autistic girls and non-autistic girls did not show consistent or significant differences in gender identity. There were no differences between the autistic and non-autistic groups in vocabulary or non-verbal reasoning in either boys or girls.

Gender identity variance may emerge early in development in autistic individuals, but the trajectory may differ for boys and girls.
