This study has as objective to evaluate the fidedignidade of the Scale of Antisocial and Criminal Conducts (Seidedos, 1988), for different Brazilian contexts, using Alpha by Cronbach, a psychometric parameter. Male and female students of public and private schools of Palmas, Paraná State, from to 21 years of age, participated in the study, in two samples:N1, with 489 subjects, and N2, with 400 subjects. They answered to the antisocial and criminal instrument of conduct which was adapted and validated to the Brazilian context by Formiga (2002). A calculus of Cronbach’s Alpha and Pearson correlation were performed, in order to guarantee the internal consistency and its precision. Those dimensions refer to the youngsters transgressive behavior and other behaviors that may characterize conducts against the law. From the results, the dependability of the instrument was confimed for another Brazilian context, what comes to guarantee the consistency and precision of its measurement system.
