Can talk therapy cut crime risk in people with personality disorders?
NCT ID NCT05523544
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looked at whether schema therapy, a type of talk therapy, can help people with personality disorders who are in outpatient forensic care. Five participants received therapy for up to two years. Researchers measured changes in their thinking patterns, risk of re-offending, and overall personality functioning. The goal was to see if this therapy could improve their lives and reduce future legal trouble.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- schema therapy (a type of psychotherapy)
- What this could lead to
- If this therapy works, it could help reduce the risk of re-offending and improve personality functioning in people with personality disorders who are in outpatient forensic care.
- What could go wrong
- This is a very small study (only 5 participants) with no control group, so results may not apply to everyone. The therapy is long-term (up to 2 years) and requires commitment.
