EPQ-A internal consistency was calculated through Chronbach's reliability coefficient, with an alpha = .810 for the neuroticism dimension (N),.678 for the extraversion dimension (E), and.702 for the psychoticism dimension (P). As for validity, the factorial structure found explains a high percentage of variance (34.26%); convergent validity was studied by means of correlations between EPQ-A and sociodemographics, criminological information, and other personality scales. Scales were determined for the first time ever in a sample of Spanish-speaking adolescents from three countries. The results suggest that the EPQ-A is a valid and reliable personality inventory in a Spanish-speaking population.
