Buss-Perry Aggression Questionnaire (BPAQ) Test

The Buss-Perry Aggression Questionnaire (BPAQ; Buss & Perry, 1992) represents a cornerstone in multidimensional trait aggression assessment, superseding earlier unidimensional models such as the Buss-Durkee Hostility Inventory (BDHI; Buss & Durkee, 1957).

Grounded in factor-analytic refinement, the BPAQ emerged from principal components analysis with varimax rotation on an initial 52-item pool, yielding four robust orthogonal factors:

• Physical Aggression (α = .85)
• Verbal Aggression (α = .72)
• Anger (α = .83)
• Hostility (α = .77)

Collectively, these factors explained 49.3% of variance in the original validation sample (N = 1,253 undergraduates; University of Texas at Austin).

Construct validity is evidenced by:

• Convergent correlations with peer-nominated aggression (r = .41–.58; Harris, 1995)
• Associations with reactive-proactive aggression typologies (r = .62 with RPQ Reactive subscale; Raine et al., 2006)
• Links to neuroendocrine markers—notably salivary cortisol reactivity during the Trier Social Stress Test (TSST; β = .29 for Anger subscale; Prado et al., 2018).

Discriminant validity is demonstrated by negligible overlap with Big Five Agreeableness after controlling for Neuroticism (partial r = −.09; Sharpe & Desai, 2001).

Cross-cultural replicability spans 33 nations (n = 8,947; meta-analytic α = .81; Archer & Coyne, 2012), with measurement invariance confirmed via multigroup CFA (ΔCFI < .01) across U.S., Japanese, and Spanish samples (Ramírez & Andreu, 2014).

Gender differences persist (Cohen’s d = 0.68 for Physical Aggression, men > women), yet latent mean differences diminish when controlling for social desirability bias (SRMR = .04; Vigil-Colet et al., 2008).

Clinical utility extends to forensic risk assessment:

• BPAQ Hostility predicts institutional misconduct in incarcerated males (incremental R² = .12 over Hare Psychopathy Checklist-Revised; Diamond et al., 2004).

In neuropsychology:

• Elevated Physical Aggression correlates with reduced prefrontal gray matter volume in vmPFC (r = −.36; Matthies et al., 2012).
• Anger mediates the 5-HTTLPR short allele × childhood maltreatment interaction on impulsive aggression (Ficks & Waldman, 2014 meta-analysis, k = 27).

Intervention studies leverage BPAQ as a change-sensitive outcome measure:

• Cognitive-Behavioral Anger Management yields large pre-post effects (Hedges’ g = 0.92 for Anger; d = 0.76 for Physical Aggression; DiGiuseppe & Tafrate, 2003 meta-analysis, k = 42).
• Mindfulness-Based Stress Reduction (MBSR) selectively reduces Hostility (g = 0.61) via decreased rumination (β = −.44; Borders et al., 2010).

Psychometric enhancements include item response theory (IRT) grading:

Two-parameter logistic models reveal high discrimination parameters (a > 1.5) for items 8 (“urge to strike”) and 23 (“powder keg”), supporting adaptive testing versions (CAT-BPAQ; 12 items, r = .94 with full form; Garcia et al., 2021).

Network analysis positions Anger as a central node bridging affective and behavioral domains (ε = 0.78; Fried et al., 2017).

Longitudinal predictive validity:

Baseline BPAQ Physical Aggression forecasts intimate partner violence perpetration at 5-year follow-up (OR = 1.41 per SD; Ehrensaft et al., 2006).

Gene-environment interplay: MAOA-uVNTR low-activity allele moderates Hostility only under high childhood adversity (G × E; Frazzetto et al., 2007).

In sum, the BPAQ’s four-factor structure, cross-method convergence, and clinical predictive power cement its status as the gold-standard self-report measure of trait aggression in social, personality, and clinical neuroscience (cited > 9,800 times; Google Scholar, 2025).
