The accuracy of 10 risk measures in predicting general and violent recidivism among 106 federally sentenced male offenders was compared. During an average period of opportunity to reoffend of 713 days ( SD = 601.38), 28 offenders recidivated nonviolently, and 34 recidivated violently. Common language effect sizes in discriminating violent recidivists from other offenders were .73 for the General Statistical Information on Recidivism–Revised and .72 for the Violence Risk Appraisal Guide. Effect sizes ranging from .58 to .68 were obtained for DSM-IV Conduct Disorder scored as a scale, the Violent Statistical Information on Recidivism–Revised, the Psychological Referral Screening Form, the Psychopathy Checklist–Revised total score and Factor 2, and the Childhood and Adolescent Taxon Scale. Effect sizes of .58 and .51 were obtained with the DSM-IV Antisocial Personality Disorder scored as a scale and the Psychopathy Checklist Factor 1, respectively.
