The relationship between the centrality of a traumatic event and symptoms of posttraumatic stress disorder after the 2011 Oslo bombing attack was investigated in the present study.

It has been proposed that a highly integrated trauma leads to more accessible and vivid memories of the traumatic event, in turn heightening symptoms of posttraumatic stress disorder. The relationship between the centrality of a traumatic event and symptoms of posttraumatic stress disorder after the 2011 Oslo bombing attack was investigated in the present study. A high degree of perceived centrality was associated with higher symptom levels of posttraumatic stress as shown in the results. This association was found after controlling for gender, age and educational background. The relationship between types and level of trauma exposure, peritraumatic reactions and centrality of event was also investigated in the present study. Higher levels of trauma exposure and peritraumatic reactions were associated with higher levels of centrality of event as shown in the results. When a traumatic event becomes a reference point in the individual’s life story and central to their identity, this is associated with an increased risk of symptomatology as suggested in the findings.
