Heterogeneity in patterns of DSM-5 posttraumatic stress disorder and depression symptoms: Latent profile analyses☆

摘要: Abstract Background Posttraumatic stress disorder (PTSD) and depression co-occur frequently following the experience of potentially traumatizing events (PTE; Morina et al., 2013). A person-centered approach to discern heterogeneous patterns such co-occurring symptoms is recommended (Galatzer-Levy Bryant, We assessed heterogeneity in PTSD symptomatology; subsequently relations between class membership with psychopathology constructs (alcohol use, distress tolerance, dissociative experiences). Methods The sample consisted 268 university students who had experienced a PTE susequently endorsed clinical levels or severity. Latent profile analyses (LPA) was used identify best-fitting solution accouring fit indices (Nylund 2007a); effects covariates analyzed using 3-step (Vermunt, 2010). Results LPA indicated an optimal 3-class solutions: high severity (Class 2), lower PTSD-higher 1), higher PTSD-lower 3). Covariates different kinds experiences differentiated latent classes. Limitations Use self-report measure could lead response biases; specific nature limits generalizability results. Conclusion found evidence for depressive subtype from other classes terms tolerance greater experiences. Thus, transdiagnostic treatment protocols may be most beneficial these members. Further, distinctiveness at comparatively supported (mainly abilities); hence supporting current classification system placement disorders.
