The present study used confirmatory factor analysis to compare the fit of seven models with a sample of 246 men and women who pled guilty to misdemeanor aggressive offenses. A large number of competing versions of the original BP-AZ have been proffered in the literature, but testing with aggressive offenders is limited. The Buss-Perry Aggression Questionnaire (BP-AQ) is a 29-item, four-factor instrument that measures physical aggression, verbal aggression, anger, and hostility.
We discuss the BAQ’s potential reliability, validity, limitations, and uses as an efficient measure of aggressive traits.
In addition, the BAQ’s 3-item Anger subscale showed convergent validity with a trait anger measure. Across 3 studies (N D 1,279), we found that the BAQ had a 4-factor structure, possessed long-term test–retest reliability across 12 weeks, predicted differences in behavioral aggression over time in a laboratory experiment, generalized to a diverse nonstudent sample, and showed convergent validity with a displaced aggression measure. Although prior work suggests the BAQ’s scores are reliable and valid, we addressed some lingering concerns. One such measure is the 12-item Brief Aggression Questionnaire (BAQ Webster et al., 2014), which uses 4 3-item subscales: Physical Aggression, Verbal Aggression, Anger, and Hostility. In contexts that increasingly demand brief self-report measures (e.g., experience sampling, longitudinal and field studies), researchers seek succinct surveys that maintain reliability and validity. The authors discuss the reliability, validity, and efficiency of the BAQ, along with its many potential applications. Across 5 studies (N = 3,996), the BAQ showed theoretically consistent patterns of convergent and discriminant validity with other self-report measures, consistent 4-factor structures using factor analyses, adequate recovery of information using item response theory methods, stable test–retest reliability, and convergent validity with behavioral measures of aggression. The authors selected the 3 highest-loading items from each of the Aggression Questionnaire’s (Buss & Perry, 1992) 4 subscales-Physical Aggression, Verbal Aggression, Anger, and Hostility-and developed an efficient 12-item measure of aggression-the Brief Aggression Questionnaire (BAQ). Researchers are increasingly demanding brief measures of aggression for use in applied settings, field studies, pretest screening, longitudinal, and daily diary studies. A key problem facing aggression research is how to measure individual differences in aggression accurately and efficiently without sacrificing reliability or validity.
