Development of the Japanese version of the Buss-Perry Aggression Questionnaire (BAQ)

The Aggression Questionnaire (Buss & Ferry, 1992) has been used to investig ate links between personality factors and health outcomes. We developed the Japanese version of the Buss-Perry Aggression Questionnaire (BAQ) and asse ssed validity and reliability of the scale. Study I (N = 1 125 college stud ents) used a 45-item rating questionnaire measuring each of four components of aggression: Anger, Hostility, Physical Aggression, and Verbal Aggressio n. Four aggression subscales emerged clearly from exploratory factor analys is. Study II (N = 611 college students) used a 24-item questionnaire and re plicated factor structure and factor loadings of Study 1. The scales were s hown to be highly internally consistent, and stable at appropriate levels o ver 4-month time period. Normative data, factorial validity, and external e vidence of construct, convergent, and discriminant validity for the scales were also presented.
