Before the crime: researchers hunt for hidden risk patterns in psychiatric records
NCT ID NCT07162909
First seen Jun 25, 2026 · Last updated Aug 20, 2026 · Updated 3 times
Summary
This study will review medical records of 500 people in Sweden who had contact with psychiatric care and later underwent a forensic psychiatric evaluation after committing a crime. Researchers will look for 26 predefined risk markers that might have appeared before the offense. The goal is to find patterns that could help psychiatric services identify people at risk and prevent future crimes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help psychiatric services identify warning signs earlier and prevent some people from progressing to forensic psychiatric care.
- What could go wrong
- This is an observational study looking back at records, not a treatment trial. It can only find patterns, not prove what causes them, and results may not apply outside Sweden.

Who is studied
Case group: individuals ≥ 18 years who had contact with at least one psychiatric care provider within Region Stockholm, Sweden. This included both clinics operated by a Swedish healthcare region and private clinics operating under regional agreements. Individuals eligible for the case group were those whose psychiatric medical records were requested by the Swedish National Board of Forensic Medicine (NBFM) in 2023 for the purpose of conducting a forensic psychiatric evaluation, either a preliminary assessment (§7 examination) or a full forensic psychiatric evaluation (FPE). Control group: Similar individuals, but whose psychiatric medical records were not requested by the NBFM in 2023 for the purpose of conducting a forensic psychiatric evaluation.
