Validation of the Buss–Perry Aggression Questionnaire-Short Form among Portuguese juvenile delinquents

The aim of the present study was to validate the Buss–Perry Aggression Questionnaire-Short Form (BPAQ-SF) among Portuguese juvenile delinquents. With a total sample of 237 male participants, subdivided into an incarcerated forensic sample (n = 192) and a community sample (n = 45), the Portuguese version of the BPAQ-SF demonstrated good psychometric properties in terms of factor structure, internal consistency, convergent validity, discriminant validity, predictive validity and known-groups validity that generally justify its use among Portuguese youth. Statistically significant associations were found with drug use and alcohol abuse.
