Assessment of violence potential using measures of anger, hostility, and social desirability.

The assessment of violence potential was studied using the following scales: The Novaco Anger Inventory, the Buss-Durkee Hostility Inventory, the MMPI Hostility Control Scale (Hc), the MMPI Overt Hostility Scale (Ho), and the Marlowe-Crowne Social Desirability Scale. The five measures were evaluated for their ability to discriminate between violent and nonviolent criminals, and between criminal and normal population samples. Normative data was collected for 204 adult male felons. A correlation matrix presents interrelationships among the five scales. A comparison of mean scale scores between violent and nonviolent groups resulted in a significant discrimination in the expected direction for all but the Hc scale. A discriminant analysis procedure applied to individual items from the Novaco Anger Inventory resulted in the selection of 25 variables which identified violence prone individuals with 90% accuracy. Clinical implications are noted and recommendations for future research are made.
