Psychometric evaluation on the Japanese adaptation of the Aggression Questionnaire

The psychometric properties of a Japanese translation of the Aggression Questionnaire (Buss & Perry, 1992, Journal of Personality and Social Psychology, 63, 452–459) were investigated. Factor analysis of the responses of 425 Japanese participants generally supported the four-factor model. The factors were Physical Aggression, Verbal Aggression, Anger and Hostility. The internal consistencies of the four subscales were adequate. The results suggested that the Japanese version of the Aggression Questionnaire met psychometric standards and appears to be a promising measure of aggression. However, the Japanese version may be improved if two reversed scored items are removed from the scale. The cross-cultural difference in responses between negatively-oriented and affirmatively-oriented questions was discussed.
