Beyond resilience and PTSD: Mapping the heterogeneity of responses to potential trauma

The formal acceptance of posttraumatic stress disorder (PTSD) as a legitimate diagnostic category in the 1980 Diagnostic and Statistical Manual of Mental Disorders stimulated a torrent of research on psychological trauma. Not surprisingly, PTSD and its treatment had dominated that research. Another common approach has been to measure the average impact of different potentially traumatic events, as well as the factors that inform that impact. In this article, we consider the limitations of these perspectives and argue for a broader theoretical approach that takes into account the natural heterogeneity of trauma reactions over time. To that end, we review recent attempts to identify prototypical patterns or trajectories of trauma reaction that include chronic dysfunction, but also delayed reactions, recovery, and psychological resilience. We consider the advantages but also the limitations and ongoing controversies associated with this approach. Finally, we introduce promising new research that uses relative sophisticated advances in latent growth mixture modeling as a means of empirically mapping the heterogeneity of trauma responses and consider some of the implications of this approach for existing trauma theories.
