abstract
Although the Antisocial Features scale of the Personality Assessment Inventory (PAI; Morey, 2007) is a robust predictor of institutional aggression, recent research (Edens & Ruiz, 2005, 2006) suggests its efficacy is limited among offenders who engage in positive impression management. In this follow-up study, we explored other PAI variables thatmight predict aggression among 134 prison inmates who Edens and Ruiz (2005, 2006) identified as producing defensive PAI profiles. Somewhat counterintuitively, the Nonsupport scale was negatively associated with aggressive-defiant and physically aggressive infractions in this subgroup of inmates. Results are discussed in the context of the threatened egotism literature and implications for institutional risk assessment are reviewed. 2009 International Association of Forensic Mental Health Services.
