“…Although several studies have examined the course of chronic PTSD (Bremner, Southwick, Darnell, & Charney, 1996;Glynn et al, 2007), most were conducted over periods shorter than 5 years. Furthermore, although a number of studies have identified risk factors for PTSD (Brewin, Andrews, & Valentine, 2000;Ozer, Best, Lipsey, & Weiss, 2003), few authors have investigated which factors predict long-term enduring or unremitting PTSD years after trauma exposure.…”
