Two hundred six male patients discharged from a maximum security psychiatric institution were followed up for a 37-49 month period. Failures were defined as men with new convictions or a readmission to the security hospital. 46% of the sample failed, usually through the commission of minor property offenses, and 17% of the total committed at least one violent offense against persons. As in earlier studies of patients discharged from this hospital, younger personality-disordered patients were more likely to fail. They were also more likely to commit a violent offense than the older nonpersonality-disordered patients.
