The Israeli government's decision to remove settlers in the Gaza Strip forcibly produced a situation of traumatic stress, resulting from confrontation and conflict for settlers. The authors examined the effects of the Gaza disengagement, that occurred following prolonged terrorist exposure, on rates of probable major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) diagnosis in a representative sample of Gaza settlers (N = 190). Predictors of probable MDD in multivariate models were being female, and experiencing greater economic and psychosocial resource loss. Predictors of probable PTSD were being older and experiencing greater psychosocial resource loss. Posttraumatic growth was significantly related to a reduction in the odds of having probable PTSD. This latter finding is interpreted within our conceptualization of action-focused growth.With the rise of war, conflict, and terrorism worldwide, there has been increased interest in studying their effects on civilian populations. Posttraumatic stress disorder (PTSD) has been found to be a product of direct exposure, proximity to an attack, knowing someone injured or killed, or having concern that a loved one might have been hurt or killed (Bleich, Gelkopf, & Solomon, 2003;Galea et al., 2002;Hobfoll, Canetti-Nisim, & Johnson, 2006;Silver, Holman, Mcintosh, Poulin, & Gil-Rivas, 2002).We examined rates of probable PTSD and MDD among Israeli settlers who, after having been exposed to ongoing terrorism, were forced to evacuate their homes and in many cases their livelihoods due to political exigencies. Settlers moved to Gaza, in part, for economic © 2008 International Society for Traumatic Stress Studies.Correspondence concerning this article should be addressed to: Stevan E.

We used Conservation of Resources (COR) theory as an organizing model for this study (Hobfoll, 1989;1998). According to COR theory, stress occurs when people's psychosocial or material resources are threatened with loss, are actually lost, or when individuals must invest resources without obtaining reasonable resource gain. Under periods of major or traumatic stress, a spiral of loss often develops, as resource loss begets further resource loss (Benight et al., 1999;Hobfoll, 1989;Norris & Kaniasty, 1996).
NIH Public AccessStudies of terrorism and other mass casualty events have found resource loss to be a principle predictor of PTSD and depression (Benight et al., 1999;Galea et al., 2002;Ironson et al., 1997). Janoff-Bulman (1992) suggested that trauma is exacerbated if it results in shattered assumptions about people's worldview. According to her model, individuals hold three basic assumptions: the benevolence of the world, the meaningfulness of the world, and a sense of self-worth. Integrating COR theory with Janoff-Bulman's (1992) concept of shattered assumptions leads to the prediction that trauma exposure and resultant resource loss would lead to PTSD and depression ...
