Psychometric evaluation of the Polish students adaptation of the Aggression Questionnaire

Abstract

The four-factor structure and psychometric properties of the Polish students adaptation of the Buss and Perry (1992) Aggression Questionnaire were investigated. The exploratory factor analyses of the responses of 604 Polish participants generally supported the four-factor model. The factors included Physical Aggression, Verbal Aggression, Anger and Hostility. The correlations between subscales, internal consistency and stability over time were evaluated and proved to be satisfactory. Apart from gender differences, 48 prison inmates and 48 students were interviewed to determine the validity of the Aggression Questionnaire by testing for hypothesized differences between groups. Aggression Questionnaire showed cross-cultural differences in aggression between various nations. © 2012, Versita. All rights reserved.
