Identifying Subtypes of Civil Psychiatric Patients at High Risk for Violence

This study was designed to identify & describe valid subtypes of patients reliably identified as at high risk by the multiple Iterative Classification Tree (ICT) risk assessment approach. Data on 165 patients identified as at high risk by the multiple ICT were used to determine whether clinically meaningful subtypes could be identified & externally validated. 3 groups largely consistent with hypothesized subtypes & their correlates were identified. Data regarding patients’ suicidal threats & attempts is included. (17 refs)
