It has been theorized that perceiving a trauma as integral to one’s identity leads to increased posttraumatic stress disorder (PTSD) symptom severity. This study evaluated the relationship between trauma centrality and PTSD symptom severity in individuals exposed to at least one traumatic event in their lifetime. Extent of trauma centrality was assessed using the Centrality of Event Scale (CES), while PTSD symptom severity was measured using the PTSD checklist civilian version (PCL-C) in a sample of adult males and females (n=71). Pearson Product Moment correlations demonstrated that trauma centrality was positively correlated with PTSD symptom severity. This study is congruent with and extends previous findings that perceiving a trauma as being central to one’s identity is associated with PTSD symptoms.
