Abstract

This study aimed to translate the Revised Aggression Questionnaire (BWAQ) by Buss and Warren into Korean and to validate the Korean version of the scale using Messick's (1995) six aspects of validity, with a focus on structural, external, and substantive validity. The research utilized confirmatory factor analysis, correlation analysis, and the Rasch model-based rating scale model. Participants included individuals aged 19 and older from 510 communities, and data were collected on various forms and levels of aggression, as well as personality traits, using the BWAQ, STAXI-K, RPQ, and NEO Adult PAS Short Form. The results of the confirmatory factor analysis identified five factors: physical aggression, verbal aggression, anger, hostility, and indirect aggression. In contrast to the original version, which includes 34 items across five factors, the Korean version of the BWAQ consists of 33 items distributed across the same five factors. Correlation analysis with criterion scales confirmed both discrimination and convergent validity. Applying Rasch-based rating scale models for each factor revealed that a 5-point rating scale was appropriate. Misfit was detected in two items: item 2 of the hostility factor and item 3 of the anger factor. Additionally, differential item functioning was noted in three items: item 7 of the anger factor, item 33 of the hostility factor, and item 34 of the indirect aggression factor. Finally, the study discusses the implications and limitations of the BWAQ, including its utility.
