Understanding Suicide Risk in Autistic Adults: Comparing the Interpersonal Theory of Suicide in Autistic and Non-autistic Samples.

Payne et al. (2020) sent online surveys to autistic and non-autistic adults.

They asked about feeling like a burden, feeling left out, and lifetime trauma.

The goal was to see if the Interpersonal Theory of Suicide explains suicidal thoughts differently in the two groups.

Autistic adults scored higher on all three pain points: burden, thwarted belonging, and trauma.

The way these pains combined to predict suicidal thinking was not the same for both groups.

In plain words, loneliness and "I’m a load" hit autistic adults harder.

Carson et al. (2017) already showed that half of surveyed autistic adults hurt themselves without wanting to die. K et al. give a reason: the mix of feeling unwanted and in the way.

Stice et al. (2019) saw the same loneliness path in college students with autistic traits. K et al. prove the pattern holds for diagnosed adults, not just students.

Hirvikoski et al. (2015) found able autistic adults feel swamped by daily stress. K et al. link that stress to the specific belief "others would be better off without me," sharpening where to intervene.

You now know that standard safety plans may miss the mark if they skip self-worth and social inclusion work.

Add brief questions about burden and belonging to your intake forms.

When either score is high, pair suicide protocols with activities that let the client feel useful and connected—like structured peer mentoring or shared-interest groups.
