The role of centrality of events in posttraumatic distress and posttraumatic growth.

Disruptions to core beliefs, rumination, and finding meaning have been associated with the development of posttraumatic distress (Janoff–Bulman, 1992, 2006). These variables have also contributed to the development of posttraumatic growth, which is the experience of a positive life change as the result of a traumatic experience (Tedeschi & Calhoun, 1996). A new variable, centrality of event, has recently been implicated in both processes (Boals & Schuettler, 2011), although it remains unclear if centrality of event is a unique contributor to posttraumatic outcomes beyond the influence of other variables known to do so. The present study examined the unique contribution of centrality of event to the development of both posttraumatic distress and posttraumatic growth. Centrality of event was a unique predictor of both variables. This seemingly paradoxical finding underscores the need for further research in this area, particularly concerning the perceived valence of a major event that may be interpreted as central. Clinicians may usefully attend to centrality when working with individuals who have experienced a potentially traumatic event.
