Abstract

Event centrality, defined as the extent to which a traumatic event becomes a core component of a person's identity (Berntsen & Rubin, 2006), is both a correlate and predictor of posttraumatic stress disorder (PTSD) symptoms, over and above event severity. These findings suggest that decreasing the perceived centrality of a traumatic event to one's identity might result in decreases in PTSD symptom severity. To date, few studies have examined how centrality is affected by PTSD treatment. The present study tested the hypotheses that change in centrality would be associated with both change in PTSD symptom severity and discharge PTSD symptom severity in an exposure-based PTSD partial hospitalization program (N = 132; 86.0% White; 85.2% female; M age = 36 years). At discharge (i.e., after approximately 6 weeks of treatment), both PTSD symptoms and centrality had significantly decreased, ds = .70 and .98, respectively, with large effect sizes. Decreases in Centrality of Events Scale (CES) scores at posttreatment, baseline CES scores, and baseline PTSD Checklist for DSM-5 (PCL-5) scores were associated with change (i.e., decrease) in PCL-5 scores, p < .001, as well as with posttreatment PCL-5 scores, p < .001. Decreases in CES scores...Continue Reading
