A look at “Efficacy of dialectical behavior therapy-based interventions for individuals with autism spectrum disorder: a systematic review and meta-analysis” by Guimei Fan, Pei Wang, Wenjing Zhang and Xiaorui Chen (2026)
A gentle note: this post mentions suicidal thoughts.
Many autistic people experience emotions that arrive like a tidal wave, and sadly, autistic people face higher rates of depression and suicidal thoughts. Dialectical behaviour therapy (DBT), originally developed for people with intense emotional distress and suicidal feelings, teaches skills in mindfulness, emotion regulation, distress tolerance and relationships. Could it help autistic people too? This Chinese review pooled the best-quality evidence.
What they found
The researchers searched six English and Chinese databases and found four randomised controlled trials, involving 375 autistic participants aged from around 10 to nearly 40.
Compared with control groups, DBT-based interventions were linked with:
- better emotion regulation;
- fewer suicidal thoughts;
- less depression.
There was no significant effect on anxiety.
Interestingly, shorter sessions (an hour or less) seemed to be linked with bigger improvements in emotion regulation than longer ones. That could reflect autistic people’s needs around energy, attention and sensory load.
A grain of glitter ✨
These are genuinely encouraging findings, especially for suicidal thoughts. But the authors themselves urge caution, and rightly so.
Four trials is a very small evidence base, and the participants ranged from children to adults in their late thirties. The trials differed enormously: sessions ranged from under an hour to four hours, some were online and some face to face, and they used different measures. The level of variation between studies (what statisticians call heterogeneity) was extremely high. That means the impressive-sounding average effects could be pulled around by one or two studies. Several trials didn’t fully report how they concealed group allocation or kept assessors “blind”, and follow-up periods were short. People with common co-occurring conditions such as epilepsy were often excluded.
The framing also leans on “social communication deficits”, with little discussion of how DBT was adapted for autistic people, or whether autistic people helped shape it.
Why this matters
If you’re autistic and struggling with overwhelming emotions, low mood or thoughts of suicide, there is hope, and help. DBT-based approaches look promising, especially when adapted to autistic ways of thinking, communicating and processing, perhaps with shorter sessions, clear structure and sensory-friendly settings. A therapist who understands autism can help tailor these skills to you.
Even the most tempestuous unicorn can learn to ride the waves. You don’t have to do it alone.
