Self-reported Suicidality in Male and Female Adults with Autism Spectrum Disorders: Rumination and Self-esteem.

Arwert et al. (2020) · Journal of autism and developmental disorders 2020
★ The Verdict

Treat depression first; it alone explains suicide risk in autistic adults.

✓ Read this if BCBAs doing intake or consultation with autistic adults.
✗ Skip if Practitioners serving only autistic children under 12.

01Research in Context

01

What this study did

Arwert et al. (2020) asked 75 adults with autism about suicidal thoughts, rumination, self-esteem, and depression.

They used surveys, not therapy. The goal was to see which thoughts most strongly link to suicide risk.

02

What they found

At first, rumination and low self-esteem looked tied to suicidality.

Once depression scores were added, those links vanished. Only depression stayed significant.

03

How this fits with other research

Hedley et al. (2017) found the same pattern: depression is the main path to suicidal thoughts in autistic adults.

Chang et al. (2024) extended the story by showing bullying and high cognitive flexibility also matter, but only in youth.

Heald et al. (2020) seems to disagree: in women with autistic traits, poor imagination plus depression predicted suicidality. The clash fades when you see they studied trait-level, not diagnosed ASD, and only females.

04

Why it matters

If depression is the driver, your first clinical move is clear: screen with a quick tool like the DASS-21 and refer for evidence-based depression care. Chasing rumination or self-esteem modules before mood is stable may waste precious time.

03Original abstract

Rumination and low self-esteem are associated with suicidality, and with autism spectrum disorders (ASD). However, rumination and self-esteem in relation to suicidality in adults with ASD have not been examined. This cross-sectional study (n = 75; 46 males and 29 females) investigates the relation of rumination and self-esteem to the absence/presence of suicidal ideation (SUIC+/-), history of attempted suicide (HAS), and severity of suicidality. Multivariate analysis of variance showed that self-esteem was significantly associated with SUIC+/-, whereas rumination was significantly associated with HAS. Multiple regression analysis showed that rumination and self-esteem were independently associated with severity of suicidality, but these lose their significant contribution, when statistically controlling for depression. The prevalence of suicidal ideation was 66.6%; gender was not a significant factor.
