The variety and crimes number reported in the media provide an seriousness overview of this problem in society today. In this context, when they are under 18 years are involved, although considered criminally incompetent and the peculiar condition of development, the discussion concerns the appropriate social response to the phenomenon has grown. It is known that the involvement level of adolescents with the practice of illegal acts is variable, so that the assessment severity of the problem is crucial to professionals who must take decisions about routing and perform the appropriate interventions. In this sense, use systematic procedures that can support the application and implementation socio-educational measures in the adolescent offenders is essential when seeking effective benefits to those considering the differences among adolescents in relation to psychological development, the personality traits, mental health conditions, social characteristics, family and education and therefore the need for interventions.

As part of procedures for adapting the PIJ, studies of validation, standardization and accuracy, as well as studies of semantic appropriateness the instrument. To determinate standards population for which the instrument was adapted is essential to ensure uniformity in the interpretation of scores and the proper data interpretation obtained with the instrument. Thus, this study proposes to develop normative standards of the PIJ in Brazilian adolescents males, aged between 14 and 18 years. The sample will consist of 250 to 350 adolescents were male, distributed by age and from public and private schools in Ribeirão Preto.
