Abstract
This scoping review explores the applicability of the Interpersonal Theory of Suicide (ITS) in understanding suicidality among autistic adults and proposes autism-specific adaptations to enhance its relevance. The review systematically examines 37 studies to assess the adequacy of the ITS in capturing the unique risk processes and factors associated with suicidality in the autistic population. The findings highlight the significance of the ITS constructs—thwarted belongingness, perceived burdensomeness, and acquired capability—in understanding suicidality among autistic individuals. Furthermore, the review identifies additional risk processes, including camouflaging, restricted interests, unmet support needs, difficulties with life transitions, the burden of comorbidities, and the exacerbating effects of depression and rumination, all of which contribute to suicidality in this population. Based on these findings, an autism-specific adaptation of the ITS, known as ITS-A, is proposed. The ITS-A extends the existing components to incorporate additional features relevant to autism and emphasises the enlarged role of perceived burdensomeness. It also recognises the potential for the presence of either thwarted belongingness or perceived burdensomeness alone to drive suicidal desire. This scoping review contributes to a comprehensive understanding of suicidality among autistic adults and offers a framework on which to base tailored suicide prevention strategies.
