Abstract
Autistic youth are more likely to experience traumatic events and may be more likely to develop trauma-related symptoms. However, accurately identifying trauma-related symptoms in autistic youth can be challenging. We examined post-traumatic stress disorder (PTSD) and other trauma-related diagnoses in youth with and without autism spectrum disorder (ASD) in a large, pediatric psychiatric emergency department (ED) in a diverse urban setting. Between March 2019 and November 2021, 2728 patients presented at our emergency psychiatric ED. Youth with ASD were 42% less likely to receive trauma-related diagnoses (prevalence ratio 0.58, 95% CI 0.41, 0.80) compared with youth without ASD. One possible explanation for this finding is that trauma-related symptoms are under-detected in youth with ASD during emergency psychiatric evaluations. There is a need for trauma screening and diagnostic instruments specifically tailored to the unique needs of youth with ASD to ensure optimal assessment and care.
Lay abstract
Autistic youth are more likely to experience maltreatment, victimization, and other traumatic events. However, it can be difficult to identify trauma-related symptoms in autistic youth, especially in those with limited verbal communication. In this study, we compared the prevalence of trauma-related diagnoses given to youth with autism spectrum disorder (ASD) to those given to youth without ASD who presented to a specialized pediatric psychiatric emergency department. We found that youth with ASD were 42% less likely to receive trauma-related diagnoses than youth without ASD. As there is evidence that youth with ASD are no less likely to experience traumatic events compared with youth without ASD, one possible explanation for this result is that trauma-related symptoms are missed during emergency psychiatric evaluations. Developing trauma screening instruments specifically designed for the needs of youth with ASD is an outstanding need.
