Information About Our Actuarial Instruments (VRAG/SORAG) for the Assessment of Violence Risk

Click here to read a brief summary of this work.

The first publication arising from this line of research was:

 Harris, G.T., Rice, M.E., & Quinsey, V.L. (1993). Violent recidivism of mentally disordered offenders: The development of a statistical prediction instrument. Criminal Justice and Behavior, 20, 315-335.

This article described the development of the Violence Risk Appraisal Guide (VRAG) though that name was not applied until two years later.

Subsequently, we described, extended, and replicated our findings in:

Rice, M.E., & Harris, G.T. (1995). Violent recidivism: Assessing predictive validity. Journal of Consulting and Clinical Psychology, 63, 737-748.
