Abstract

Jesness Inventory - revised brazilian (IJ-R-Br) is a tool for evaluating the personality of juveline offenders, whohas demonstrated good psychometric qualities, especially the results obtained in the Brazilian context. TheInventory assess aspects of Personality related to Delinquency; attitudes and antisocial values, problems withauthority and traits of impulsiveness, hostility and sensation seeking. In Brazil, adolescents with different levels ofdifficulties get caught by the juvenile justice system, being able to receive very similar measures. This is becausethere are no systematized evaluation practices that support judicial decisions. As this is a specific population, anevaluation should be as short as possible. This study aims to develop the reduced version of the Brazilian JesnesInventory and to evaluate its psychometric properties (concurrent validity, convergent validity, construct validity,internal consistency and temporal stability). Will participate in the study between 490 and 560 male adolescents ,coming from public and private schools. Adolescents will respond to four self-report instruments:Sociodemographic Characterization Questionnaire, reduced version of the Jesness Inventory, Self-reportedDelinquency Questionnaire and Factorial Socialization Scale (EFS; Huntz and Nunes, 2007). A plot of 105adolescents will respond to the reduced version of the Inventory of Jesness at a second time in order toinvestigate the temporal stability of the instrument. The appropriate descriptive and inferential statistical analyzeswill be performed in order to obtain, respectively, normative data and evidences for the evaluation of thepsychometric properties.
