Locus of control in US combat veterans: Unique associations with posttraumatic stress disorder 5-factor model symptom clusters

Posttraumatic stress disorder (PTSD) is a common and often debilitating psychological disorder that develops in roughly 7-8% of individuals after exposure to trauma (Kessler et  al., 2005; Kilpatrick et al., 2013). Rates of PTSD are even higher among veterans who served in Iraq and Afghanistan (Harpaz-Rotem et al., 2011; Ramchand et al., 2010). Moreover, PTSD is a heterogeneous disorder comprised of several factors, each potentially governed by different neurobiologica l underpinnings (e.g., Grupe et al., 2016; Pietrzak et al., 2015; for a review see Sherin and Nemeroff, 2011).
