The BPAQ-SF: A Brief Measure of Trait Aggression

The 29-item Aggression Questionnaire (AQ; Buss & Perry, 1992) is one of the most popular self-report measures of trait aggression. It yields four useful factors (i.e., Physical Aggression, Verbal Aggression, Anger, and Hostility); however, the four-factor structure of the AQ has not always been confirmed, raising questions about the structure of the measure.

Bryant and Smith (2001) developed a 12-item short form of the AQ that retains the four-factor structure and appears to have some psychometric advantages over the original, including improved model fit. This version, referred to as the Buss-Perry Aggression Questionnaire - Short Form (BPAQ-SF) in the literature, provides researchers interested in studying aggression with a more efficient alternative to the AQ.

In addition to Bryant and Smith's (2001) work testing the BPAQ-SF in multiple data sets, Kalmoe (2015) found support for the BPAQ-SF in nationally representative U.S. and college student samples. Slightly modified versions of the BPAQ-SF have also been used with mentally ill male offenders (Diamond, Wang, & Buffington-Vollum, 2005) and federal offenders (Diamond & Magaletta, 2006).

Thus, the BPAQ-SF provides researchers wanting to measure trait aggression with a relatively brief but psychometrically sound option.
