Suicidality in Children with Elevated Autistic Traits.
Autistic traits raise suicide risk only through anxiety and depression, so target those feelings first.
01Research in Context
What this study did
The team asked 1,123 Chinese school kids to fill out three short forms.
One form measured autistic traits, one asked about suicidal thoughts, and one tracked anxiety and mood.
Children were 8-14 years old and attended regular classes.
What they found
Every 10-point jump on the autism-trait score raised suicide-risk odds by 30-a large share.
Anxiety and depression explained almost all of that link.
Good grades and close families did not lower the risk.
How this fits with other research
Adams et al. (2020) show the same anxiety drags down both the child’s and the parents’ quality of life.
MacLennan et al. (2020) add that kids who are sensory-over-reactive are the ones most prone to phobia-type anxiety.
Adams et al. (2025) then show this same anxiety is the strongest predictor of later school refusal.
Together the four papers draw one line: anxiety is the common engine driving suicidality, poor well-being, and absenteeism in autistic youth.
Why it matters
You already watch for self-injury, but now you know to treat anxiety as a red-flag for suicide risk even when grades and family look fine.
Screen every autistic client for anxiety and depression, not just the autism itself.
A brief CBT or coping-skills plan may do more to keep the child safe than any academic support you add.

03Original abstract
By using a nationally representative school-based sample (4,816 children aged 8-14 years), we examined the risk of suicidality in children with elevated autistic traits and assessed the mediation of anxiety/depression and moderation effects of family function and academic performance. The Chinese version of the Social Responsiveness Scale (SRS-C) was used to measure autistic features. Logistic regression models were applied to assess associations between autistic traits and suicidality (suicidal ideation, suicide plans, and suicide attempts) for estimating the mediation effects of anxiety/depression and moderation effects of academic performance and family function after adjustment for control variables. Every 10-point increase in the SRS-C score was associated with a 1.3-1.4-fold increase in suicidality risk. Associations relating to suicide plans and attempts were fully mediated; however, the association with ideation was partially mediated by anxiety/depression. Academic performance and family function did not appear to moderate associations between autistic traits and suicidality. In conclusion, children with elevated autistic traits exhibited increased risk of suicidality, which could be generally attributed to symptoms of anxiety/depression. Because adequate family function and academic performance did not mitigate the link between elevated autistic traits and suicidality, in-depth exploration into specific protective factors in children with elevated autistic traits is warranted. LAY SUMMARY: By using a nationally representative school-based sample (4,816 children aged 8-14 years), we observed that the risk of suicidality increased in children with elevated autistic traits. This association was generally explained by increased levels of anxiety/depression. Furthermore, better family function and academic performance did not appear to mitigate the link between autistic traits and suicidality.
