Suicide Risk

In The Politics of Autism, I write about the many challenges facing people on the spectrum.  Among many other things, they are at high risk for suicide. (In July, the United States transitioned from 10-digit National Suicide Prevention Lifeline to 988 – an easy-to-remember three-digit number for 24/7 crisis care. "

Abstract:

The purpose of this review is to provide a comprehensive update of literature published between January 2018 and April 2024, examining suicidal thoughts and behavior (STB) prevalence, risk factors, theoretical models, and interventions in autism.

Recent findings

We identified four recent meta-analyses and two systematic reviews. Pooled prevalence estimates in autism ranged from 34.2% for suicide ideation to 24.3% for suicide attempts. Autistic traits, interpersonal factors, and depressive symptoms were identified as STB risk factors, with elevated risk observed across the lifespan.
Summary

We included 80 studies examining STB in diagnosed autistic people or autistic traits in non-clinical samples. Autistic people were found to have an up to eightfold increased risk of death by suicide compared to non-autistic people, although reported rates varied considerably between studies; co-occurring mental health conditions, social, psychological, and cognitive factors exacerbated risk. Validated STB assessment tools and interventions for autistic people were notably scarce.
