The short-form Buss-Perry Aggression Questionnaire (BPAQ-SF) - A validation study with federal offenders

The 12-item short form of the Buss-Perry Aggression Questionnaire (BPAQ-SF) was originally developed by Bryant and Smith (2001) and modified and confirmed using confirmatory factor analysis with mentally ill offenders by Diamond, Wang, and Buffington-Vollum (2005). In the current study, construct validity of the BPAQ-SF was assessed with a sample of 1,181 male and 435 female general population federal offenders. Confirmatory factor analysis supported the four factor structure. Tests confirmed factorial invariance across gender for all loadings and covariances. Reliabilities were found to be adequate and comparable to those found in the studies cited above. Concurrent validity was supported by high correlations between the subscales of the BPAQ-SF and several relevant subscales on the Personality Assessment Inventory (PAI). In addition, those offenders with prior history of violence, head injuries, childhood abuse, residential treatment, custody, or foster care as a child had higher scores on the BPAQ subscales.
