Document Summary
1960s, civil rights concerns provided rare opportunity to study the accuracy of mental health professionals in predicting violence. Two key findings in research (baxtrom and dixon: base rate for violence is relatively low, false positive rate is very high. Findings indicate that in the past many mentally disordered forensic patients were needlessly kept in restrictive institutions based on erroneous judgments of violence risk. Assessment assumes that risk can be measured. In reality, sample available for evaluating a risk-assessment instrument is limited to those with a relatively low risk of reoffending. Monahan and steadman (1994) three main weaknesses of research on prediction of violence: 1) concerns the limited number of risk factors being studied. Violet behavior is due to a complex interaction between individual dispositions and situational factors. People who engage in violence for many different reasons. Assessment may be improved by measuring more of the reasons why people engage in violence: 2) concerns how the criterion is variable is measured.
