Discriminating Between Violent and Nonviolent Disturbed Criminal Offenders.
Perkins, Kenneth A.; Moore, Danny
Predicting occurrences of violent behavior in the population of emotionally disturbed criminal offenders was investigated by identifying a pattern of characteristics that significantly discriminates between violent and nonviolent offenders. Subjects were 149 current and former male patients in the Forensics Division of St. Elizabeths Hospital in Washington, D.C. who had committed at least two violent crimes (N=79) or no violent crimes (N=70). Data were obtained from patient files. Univariate analyses showed that factors of education, occupation, age at which first institutionalized, juvenile delinquency, absence of father, and length of time institutionalized before age 18 distinguished significantly between the violent and nonviolent groups. Factor analysis was utilized to reduce the number of predictor variables, and those which emerged were juvenile criminal history, parental absence, socioeconomic status, and family experience. A step-wise discriminant analysis using these reduced factors was then performed on each of two samples formed by randomly splitting the violent group and nonviolent group. All four factors emerged in both discriminant functions. Analyses demonstrated the significance of each function in assigning subjects within the same sample and subjects in the other sample (cross-validation) to the proper classification. (Author)
