The Inventário de Jesness – revisado brasileiro (IJ-R-Br) assess psychological aspects of adolescent offenders. The objective of this study was to obtain evidence of reliability and criterion validity of two IJ-R-Br’s subscales. The responses of 928 male adolescents to the IJ-R-Br and the Questionário de Comportamento Juvenis (QCJ) were analyzed. Reliability was calculated by Cronbach’s alpha and Spearman- Brown coefficient. The criterion validity, through the Student’s t-test, of chi-squared and relative risk analysis, was used to verify the association between high scores on measures and high indicators of infractional engagement (measured by QCJ). The accuracy scores were unsatisfactory only for three of 12 Inventory scales. Regarding the criterion validity, there are more adolescents with high indicators of infractional engagement in the group with high scores. It is opportune to conduct research with a population of teenage offenders.
