Event centrality influences posttraumatic stress disorder symptoms via core beliefs in internally displaced older adults

Abstract

ABSTRACTObjectives: There is substantial evidence regarding the role of event centrality (EC) in posttraumatic stress disorder (PTSD) symptoms, but little research has examined the explanatory pathways linking EC with PTSD symptoms severity. The present study examined whether core beliefs (CB) mediates the relationship between EC and PTSD symptoms in internally displaced older adults.Method: Internally displaced older adults (N = 279; mean age = 62 years) sheltered in two camps located in north-central Nigeria, completed Tiv language versions of self-report measures, namely, the Harvard Trauma Questionnaire, the Centrality of Event Scale, Core Beliefs Inventory, and provided relevant demographic information.Results: Analysis indicated that EC and CB were linked to greater PTSD symptoms as well as re-experiencing/intrusion, avoidance and hyperarousal symptoms severity. The mediator path was significant which implies that CB was a pathway through which EC influences PTSD symptoms clusters and overall PTSD symptomatology.Conclusion: A traumatic event becoming more central in a person's identity and life story distorts entrenched beliefs about oneself, others and the world, thereby resulting in greater PTSD symptoms. Our findings suggest that considerations of disrupted world assumptions may be a salient target for prevention and treatment efforts.
