OxRisk (@Oxriskis a project by the Forensic Psychiatry and Psychology group at the University of Oxford.

We have developed eight freely available web-based risk calculators:

OxRec – Risk of Recidivism Tool, also available in Swedish, Greek, French, ChineseRussian, Italian, Spanish, FinnishGerman, and Polish.

OxMIV – Mental Illness and Violence Tool, also available in Greek, German, French, Chinese, Spanish, Russian, and Italian.*

OxMIS – Mental Illness and Suicide Tool, also available in Arabic, French, Chinese, German, and Spanish.

FoVOx – Forensic Psychiatry and Violence Tool, also available in German, Chinese, RussianItalian, and Swedish.

FoxWeb – Inpatient violence monitoring tool with a focus on modifiable factors.

OxRIS – Oxford risk of recidivism of sexual offenders, including three separate tools for violent reoffending, any reoffending, and sexual reoffending.

OxDOV – Oxford risk of reoffending in individuals arrested for domestic violence perpetration, including three separate tools for violent reoffending, any reoffending, and domestic violence reoffending.

OxSATSOxford Suicide AfTer Self-harm Tool – provides a probability score for suicide risk in 6 months and 12 months after a self-harm episode presenting to secondary healthcare (emergency department/specialist care).
