“…Individuals in certain occupations, termed “occupations at risk,” such as firefighters, law enforcement, emergency workers, and military personnel, are at greater risk of developing PTSD due to their increased frequency of trauma exposure. For example, studies of disaster workers have found rates of PTSD ranging from 9% to 35% (Harvey-Lintz & Tidwell, 1997; Marmar et al, 1999; North, Tivis, McMillen, Pfefferbaum, Cox, et al, 2002; North, Tivis, McMillen, Pfefferbaum, Spitznagel, et al, 2002; Rosenczweig, Kravitz, & Devlin, 2002); emergency medical workers have estimated PTSD rates of 21% (Bennett et al, 2005; Clohessy & Ehlers, 1999; Jonsson, Segesten, & Mattsson, 2003); and Iraq and Afghanistan (OIF/OEF/OND) combat veterans have an estimated PTSD prevalence rate of 25% (Gentes et al, 2014; Hoge, Terhakopian, Castro, Messer, & Engel, 2007; Ramchand et al, 2010; U.S. Department of Defense, U.S. Department of Veterans Affairs, U.S. Department of Health and Human Services, & U.S. Department of Educaton, August 2013).…”
