Intimate partner violence, PTSD, and adverse health outcomes

The high prevalence of adverse health outcomes related to intimate partner violence (IPV) is well documented. Yet we know little about the pathways that lead to adverse health outcomes. Research concerning the psychological, biological, neurological, behavioral, and physiological alterations following exposure to IPV--many of which are associated with posttraumatic stress disorder (PTSD)--represents a promising area of empirical discovery. New technologies and interdisciplinary collaborative efforts are required to integrate diverse methodologies and to apply new findings to improving the health and well being of those affected by IPV. This article focuses on victimization by IPV and addresses the most important research findings in the last 20 years (health and mental health burden of IPV), the most important research issue for the next decade (pathways between IPV and adverse health outcomes), and the most promising methodological innovation for the study of IPV (integrated, interdisciplinary, biobehavioral methodology).     

Support for emergency department screening for intimate partner violence depends on perceived risk

Emergency department (ED) screening for intimate partner violence (IPV) faces logistic difficulties and has uncertain efficacy. We surveyed 146 ED visitors and 108 ED care providers to compare their support for ED IPV screening in three hypothetical scenarios of varying IPV risk. Visitor support for screening was 5 times higher for the high-risk (86%) than for the low-risk (17%) scenario. Providers showed significantly more support for the need for ED IPV screening than visitors. Controlling for confounding by gender, race, experience with IPV, hospital, and marital status did not affect comparisons between groups. These responses indicate greater support for IPV screening in the ED for high-risk than for low-risk cases, particularly among visitors.     

Psychopathy Factors and Risk for Aggressive Behavior: A Test of the “Threatened Egotism” Hypothesis

The primary purpose of this study was to examine psychopathy within a model of aggressive behavior that encompasses narcissism and "threatened egoism." This model was advanced by Baumeister and his colleagues (e.g., R. F. Baumeister, L. Smart, & J. M. Boden, 1996; B. J. Bushman & R. F. Baumeister, 1998). We examined whether the threatened egotism model extends to the construct of psychopathy and whether the two factors underlying psychopathy exhibit different associations with aggression within this model. Self-report data, correctional officer and counselor reports, and disciplinary report information obtained for 98 male inmates provided partial evidence that psychopathic individuals tend to respond aggressively when confronted with an ego threat. Moreover, psychopathic individuals exhibited this pattern of aggression more strongly than did narcissistic individuals. These findings bear potentially useful implications for the understanding and treatment of aggression in forensic populations.
