Abstract

Adults diagnosed with autism are at significantly increased risk of suicidal thoughts, suicidal behaviours and dying by suicide. However, it is unclear whether any validated tools are currently available to effectively assess suicidality in autistic adults in research and clinical practice. This is crucial for understanding and preventing premature death by suicide in this vulnerable group. This two stage systematic review therefore aimed to identify tools used to assess suicidality in autistic and general population adults, evaluate these tools for their appropriateness and measurement properties, and make recommendations for appropriate selection of suicidality assessment tools in research and clinical practice. Three databases were searched (PsycInfo, Medline and Web of Knowledge). Four frequently used suicidality assessment tools were identified, and subsequently rated for quality of the evidence in support of their measurement properties using the COSMIN checklist. Despite studies having explored suicidality in autistic adults, none had utilised a validated tool. Overall, there was lack of evidence in support of suicidality risk assessments successfully predicting future suicide attempts. We recommend adaptations to current suicidality assessment tools and priorities for future research, in order to better conceptualise suicidality and its measurement in autism.

  • Autism often co-occurs with psychological comorbidities, including suicidality, anxiety disorders, and mood disorders like depression.

    “As previously mentioned, autism often co-occurs with several additional psychological comorbidities, including suicidality, anxiety disorders, and mood disorders like depression (Cassidy et al., 2018;Hollocks et al., 2019).”

    From Rethinking psychological interventions in autism: Toward a neurodiversity‐affirming approach. (2025) · cites this paper as Cassidy et al., 2018

    The Introduction states that autistic adults are at high risk of suicidality compared with other clinical groups. It does not establish that anxiety disorders or mood disorders such as depression often co-occur with autism; those terms appear in the cited references, but the references alone do not support that part of the claim.

  • The TAS-20 has never undergone a thorough examination as to whether autistic individuals understand items in the same way as non-autistic people.

    “Another instance is the TAS-20, which despite being robustly used in autism research (see, for instance, [80, 82, 141]), has never undergone a thorough examination (e.g. [118, 119]) as to whether autistic individuals understand items in the same way as non-autistic people”

    From A 'choice', an 'addiction', a way 'out of the lost': Exploring self-injury in autistic people without intellectual disability (2019) · cites this paper as [119]

    The Introduction discusses how autistic people may interpret questions differently, and §5.1 recommends comparing suicidality measures across autistic and non-autistic groups. Neither section addresses the TAS-20 or whether its items have undergone the examination claimed; searches for TAS-20 and Toronto Alexithymia Scale found no relevant passage in our copy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
