The current archival study assesses risk factors associated with recommitment of 142 individuals adjudicated Not Guilty by Reason of Insanity (NGRI) from civil settings to a forensic hospital in New York State. Within 10 years of transfer from a forensic hospital, 40 (28.2%) were recommitted. Using survival analyses to account for the wide range in opportunity for recommitment, period of transfer (i.e., pre versus post the 1995 case of George L, which clarified factors related to assessments of dangerousness) and the Historical scale and specific items of the HCR-20 emerged as important risk factors for recommitment. Specifically, hazard of recommitment was 2.9 times higher for those with high Historical scores as compared to those with low scores. However, few individual risk factors were associated with recommitment. Prior supervision failure, negative attitude, problems with substance use, and absent or less serious major mental illness and relationship problems were informative in predicting recommitment over 10 and 3 year follow-up periods.
