Simple versus complex PTSD: a cluster analytic investigation.
A cluster analytic investigation was conducted on measures of PTSD associated features (e.g., personality pathology, dissociative tendencies) to investigate whether empirically-defined clusters correspond to Herman's [1992, Complex PTSD: a syndrome in survivors of prolonged and repeated trauma. Journal of Traumatic Stress, 5, 377-391; 1997, Trauma and recovery (Rev. ed.). New York: Basic Books] distinction between simple and complex PTSD. Results from a sample of 60 PTSD patients were broadly consistent with this distinction, although some inconsistencies were observed. Treatment outcome generally did not differ between the two clusters. Implications for classifying and treating PTSD are discussed.
