Japanese version of the Displaced Aggression Questionnaire

Past research has indicated that individual differences in trait displaced aggression could predict aggressive behavior, such as domestic abuse. A Japanese version of the Displaced Aggression Questionnaire (DAQ; Denson, Pedersen, & Miller, 2006) was developed and tested on university and technical college students (N = 777, age range : 18-24). Factor analyses identified 3 factors in the 31-item structure (alpha = .93) : angry rumination (alpha = .92), revenge planning (alpha = .92), and general tendency to engage in displaced aggression (alpha = .93). This structure was the same as that of the original English version. Multiple regression analysis revealed that the Japanese version of the Displaced Aggression Questionnaire predicted domestic verbal abuse (beta = .29, p < .001), whereas the Japanese version of the Buss and Perry Aggression Questionnaire (Buss & Perry, 1992) did not (beta = .10, ns). These results indicate that the Japanese version of the Displaced Aggression Questionnaire may be useful for utilizing trait aggression to predict domestic verbal abuse of students.
