As of December 2012, the DoD’s Defense Medical Sur- veillance System database reported 131,341 active-duty service members diagnosed with PTSD.2 In a meta- analysis across studies since 2001, 13.2 percent of operational infantry units met overall criteria for PTSD, with PTSD in- cidence rising dramatically from 25 to 30 percent in those units experiencing the highest levels of direct combat.3 During this same period, the prevalence of PTSD among discharged veterans receiving treatment at VA clinics has been reported at 29 percent.2 These findings make a compelling case for a continued focus on developing and enhancing diverse evidence-based treatment options for combat-related PTSD.
