Suicide is a major problem in Western society. However we have very little 
understanding of suicidal behaviour among individuals with autism spectrum 
disorders. The purpose of this review is to synthesise primary research on 
suicidal behaviour among adolescents and young adults with autism spectrum 
disorders in order to estimate prevalence and to identify and critically 
evaluate risk factors for suicidal behaviour in this population. Four primary 
research studies were identified for this review following a comprehensive 
literature search. The available research provides little empirical evidence for 
the processes underlying suicidal behaviour in adolescents and young adults with 
autism.
