This case study, published in the American Journal of Psychiatry, presents an overview of the conceptualization and treatment of two veterans of the Iraq War who presented for combat-related treatment at a Veterans Administration Medical Center. In addition to posttraumatic stress disorder (PTSD) symptoms of re-experiencing, arousal, and avoidance, the veterans exhibited compulsive checking behaviors that appear to be influenced by theater-specific combat duties and traumatic events. These cases represent what the authors believe to be an increasingly common expression of PTSD in veterans of the Iraq and Afghanistan wars.
