The aim of this study was to select items for the composition of the reduced Brazilian version of the Jesness Inventory - Revised, a specific instrument for the psychological evaluation of juvenile offenders. Data from 954 adolescents of the population aged between 11 and 18 years were used. Analyses using the Item Response Theory Exploratory Model (IRTEM) and then the Item Response Theory Confirmation Model (IRTCM) were performed for each scale of the instrument. In the IRTEM stage, items with an unacceptable α were excluded and in the IRTCM stage only items with moderate or high α values were maintained. Subdimensions were found in the scales. This led to a version with 86 items. The strategies adopted allowed the selection of items with greater discriminative/explanatory capacity and the identification of subdimensions through preliminary content analysis helped in the comprehension of the construct.

Palabras clave : juvenile delinquency; psychological assessment; personality measurement; item response theory.
