Abstract
The aim of this study was to validate and determine the reliability of Youth Self Report (YSR/11-18) in Chilean adolescents. The sample consisted of 816 adolescents, aged 11 to 18 years, from a private school in the city of Calama, where we applied and the Latin version of the questionnaire. Following the steps outlined by Achenbach, was made a principal components analysis for the derivation of the syndromes of first and second order. The results show high consistency and validity of the instrument, which makes the YSR/11-18 a test of predictive value in Chile, allowing not only to assess social and behavioral skills, but could be transformed into an instrument that would allow the early identification of risks in the adolescent population.
