Psychometric evaluation of the Dutch version of the Aggression Questionnaire.

Confirmatory factor analyses were done in an attempt to replicate the factor structure of the Aggression Questionnaire constructed by Buss and Perry (1992) [Journal of Personality and Social Psychology, 63, 452-459] in a Dutch sample. The findings indicated that the Buss and Perry 4-factor model provided a poor fit to the full 29-item questionnaire. Although generally confirming the 4-factor structure, subsequent analyses revealed that a better fit was obtained by omitting 3 items (1 Verbal Aggression and 2 Hostility items). In general, the present findings are rather similar to previous research and emphasize the importance of assessing not only overall aggression but also its separate components.
