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.

Notes

  1. 1.

    Consistent with the most recent edition of the Publication Manual of the American Psychological Association (2019), and the preferences of individuals with lived experience of autism (Bury et al., 2020), we utilise identity first language.

  2. 2.

    Permission to be identified and quoted in this chapter provided by W.A. via personal communication with author D.H., June 28, 2020.

  3. 3.

    At the time of writing, Max is supported by a multidisciplinary team. Team members have experience with autism and are willing to learn about Max’s needs and wishes for the future. Max has an Assistance Dog and is beginning to venture outside again. Whilst suicide attempts have now stopped, Max continues to experience suicidal ideation to varying degrees.
