The Brief Aggression Questionnaire: Turkish Validity and Reliability Study

Abstract

The aim of this study is to test the psychometric properties of the "Brief Aggression Questionnaire (BAQ)," originally developed by Buss and Perry (1992) and revised into a short form by Webster et al. (2014), for Turkish adolescents and adults. The study group consisted of individuals aged 14–52, which is a total of 213 participants, including 168 males (mean age = 29.79) and 45 females (mean age = 26.50), selected through convenience sampling. The construct validity of the questionnaire was tested using Confirmatory Factor Analyses (?2=447.78, p<0.05, ?2/df= 1.88, CFI= .97, SRMR= .032, and RMSEA= .034). For the convergent validity of the measurement tool, t-values, factor loadings, and Average Variance Extracted (AVE) were calculated; for discriminant validity, the values of Average Shared Variance (ASV), Maximum Shared Variance (MSV), ?AVE, and inter-factor correlations were determined. Additionally, reliability analyses, including the internal consistency coefficient (Cronbach's Alpha) and Composite Reliability (CR) values, were computed. Our findings indicate that the BAQ is a reliable four-factor measurement tool that can be used to assess aggression in Turkish adolescents and adults.
