Abstract

Evidence suggests increased rates of suicidality in autism spectrum disorder (ASD), but the research has rarely used comparison samples and the role of emotion dysregulation has not been considered. We compared the prevalence of parent-reported suicidality ideation and considered the role of emotion dysregulation in 330 psychiatric inpatient youth with ASD, 1169 community youth with ASD surveyed online, and 1000 youth representative of the US census. The prevalence of suicidal ideation was three and five times higher in the community and inpatient ASD samples, respectively, compared to the general US sample. In the ASD groups, greater emotion dysregulation was associated with suicidal ideation. Implications include consideration of emotion regulation as a potential mechanism and treatment target for suicidality in ASD.
