The Aggression Questionnaire for Spanish preadolescents and adolescents: AQ-PA.

We have already published the psychometric properties of our Spanish version of the Buss and Perry's Aggression Questionnaire adapted to young subjects (Personality and Individual Differences, 42, 1453-1465). The four-dimensional structure of the questionnaire was confirmed in each pre-adolescent and adolescent sample, although differences in the intercorrelations among factors between both groups of age were then observed. We publish now new evidences about its factorial validity in the whole group of pre-adolescent and adolescent children. We also report the positive correlations found between measurements obtained with this questionnaire (AQ-PA) and other aggression and anger scales (DIAS, STAXI and EXPAGG) and the Barratt Impulsiveness Scale (BIS-11), which provide more evidences about its convergent validity. The text of the Spanish version of this questionnaire adapted to pre-adolescent and adolescent subjects is also reported.
