Samenvatting

Although the heterogeneity of posttraumatic stress (PTS) symptoms has been well-documented in various traumatized samples, no study has investigated the heterogeneity of DSM-IV PTS symptomatology in samples exclusively comprised of bereaved people. We examined what classes could be distinguished based on the endorsement of self-rated DSM-IV PTS symptoms in a sample of 509 bereaved people confronted with losses due to a variety of causes and a sample of 331 homicidally bereaved people. Associations between class-membership and sociodemographic and loss-related variables were also examined. Based on latent class analyses, conducted in both samples separately, we identified three PTS classes: a No disturbance, Intermediate disturbance, and Pervasive disturbance class, characterized by low, moderate, and high probability of endorsement of PTS symptoms, respectively. In both samples, the largest class was characterized by participants who endorsed intermediate PTS symptom levels. As expected, being a woman, more closely related to the deceased person, more recently bereaved, and (in the sample of 509 bereaved people) confronted with unexpected loss were related to classes with more PTS disturbances. There is evidence that intermediate PTS levels are associated with negative outcomes. Because this seems to be a relative large group in the current study, it is useful to further our knowledge about variables underlying and maintaining subclinical PTS levels.
