ABSTRACT
People who are diagnosed with Autism Spectrum Disorder (ASD) are at increased risk of suicidal behaviour compared to the general population;recent population-based studies demonstrate a three- to sevenfold increased risk of premature death by suicide. This chapter provides an overview of: (a) the current literature regarding risk and prevalence of suicide behaviour in autism;(b) the role of intellectual disability/intellectual developmental disorder in suicide in autism;(c) correlates, risk and protective factors;(d) dimensional constructs of suicide, including autistic traits;(e) current approaches to suicide assessment, including potential modifications;and (f) suicide prevention and service access. We consider these topics by drawing on state-of-the-art research, the perspective of lived experience, and consideration of the potential impacts of major events such as the coronavirus (COVID-19) pandemic.
