The Buss-Perry Aggression Questionnaire (BPAQ) is a 29-item self-report measure that includes four subscales (Buss & Perry, 1992): physical aggression (9 items), verbal aggression (5 items), anger (7 items), and hostility (8 items) (Buss & Perry, 1992). There is no time frame specified, and items are rated using a seven-point scale from “extremely uncharacteristic” to “extremely characteristic”.
