As the United States of America has been involved in near-constant combat for much of the past decade, increasing numbers of soldiers are returned home with not only physical injuries, but also mental injuries. This review of research articles will examine the study titled “Anger, Hostility, and Aggression Among Iraq and Afghanistan War Veterans Reporting Post-Traumatic Stress Disorder and Subthreshold Post-Traumatic Stress” conducted by Matthew Jakupcak, Daniel Conybeare, Lori Phelps, Stephen Hunt, Hollie Holms, Bradford Felker, Michele Klevens. and Miles E. McFall of the Veterans Administration (VA) Puget Sound Health System, Seattle, Washington. The study was published in the Journal of Traumatic Stress, Vol. 20, No.6, December 2007. The main concept of the research was to attempt to confirm the association between PTSD and angry and/or hostile behavior in combat-exposed veterans (as cited in Orth and Wieland, 2006). The study examined 117 veterans who sought help from the VA over a 13-month period and divided participants into three categories: PTSD, subthreshold PTSD, and non-PTSD and correlated the results (Jakupcak, Conybeare, Phelps, Hunt, Homles, Felker, Klevens & McFall, 2007, pp. 947, 948). The study hypothesized that veterans who were reported to test positive for PTSD on clinical examinations after self-referral would report significantly increased anger and hostility after completing a self-report questionnaire compared to those with subthreshold PTSD or those in the non-PTSD group (Jackupcak et al, 2007, p.947). Additionally, researchers hypothesized that the subthreshold-PTSD group would display higher traits of anger and hostility than the non-PTSD group (Jackupcak et al, 2007, p. 947).

This would apply not only to the military, but to any profession with a greater risk of exposure to traumatic events such as police personnel, paramedics or emergency services.
