Theory and evidence suggest that attitudes toward violence are relevant for the explanation, prediction, and reduction of violent behavior. The purpose of the present study was to adapt a measure of violent attitudes-the Evaluation of Violence Questionnaire (EVQ)-for use in Portugal, test the cross-country equivalence, and test the validity of both versions. We found the expected one-factor structure, high internal consistency, and cross-country measurement invariance for the Portuguese and original EVQ with men in Portugal (N = 320) and Canada (N = 298). We also found the expected pattern of correlations with measures of more versus less theoretically relevant constructs: both versions of the EVQ showed the strongest correlations with overall aggression and reactive aggression; slightly lower correlations with proactive aggression; negative correlations with self-control; and the smallest correlations with self-esteem. Our results support the equivalence, reliability, and validity of the Portuguese and original versions of the EVQ.
