Autistic adults die more often by suicide than people who are not autistic and there is an absence of effective support for autistic people who experience suicidal thoughts and behaviours. One limiting factor is a lack of theoretically driven research to provide detailed insight into mechanisms driving suicide amongst autistic people. One research priority identified by the autism community is to explore the extent to which existing models of suicide describe the experiences of autistic people. Thus, this set of studies aims to explore this with reference to the most widely cited suicide theory, the Interpersonal Theory of Suicide (Joiner 2005).
