abstract="BACKGROUND: Assessment of risk of violent behavior in forensic psychiatric practice is a complex and responsible clinical task and the use of a valid instrument can make the expert's work more effective. The Historical Clinical and Risk Management scale 20 (HCR-20) is a widely accepted measure of the risk of violence, sexual and criminal behavior. The aim of this study was to validate the HCR-20 in Israeli psychiatric inpatient settings. <br><br>METHOD: In a prospective design, data were collected on 150 male patients aged 15-65, diagnosed with ICD-10 schizophrenia, who were hospitalized in three wards: an acute psychiatric ward (n=50), a high security ward (n=50), and an open ward (n=50). The HCR-20, as the predictor measure, and the Positive and Negative Syndrome Scale, as a concurrent measure, werecompleted at baseline, and the Violence Assessment Scale, as the outcome measure, was completed at 6-, 12- and 18-month follow-up points. <br><br>RESULTS: Internal consistency reliability was good for the total HCR-20 scale, satisfactory for the H-subscale, but low for the C- and R-subscales. Concurrent validity was good for the C-subscale, and discriminative validity was reasonable for the C- and H-subscales. The total scale as well as the Historical and Clinical subscales predicted the risk of physical as well as physical/sexual violent behavior at both 6- and 18-month follow-up points. <br><br>CONCLUSIONS: Appropriate psychometric properties of the HCR-20 suggest that it can serve as a useful measure of the risk of violent behavior in psychiatric settings in Israel. Further research is necessary to confirm norms and cut-off scores, using a larger representative sample.<p /> <p>Language: en</p>",
