Evidence for two different ICD-11 posttraumatic stress disorders in a community sample of adolescents and young adults


Perkonigg, Axel; Höfler, Michael; Cloitre, Marylène; Wittchen, Hans-Ulrich; Trautmann, Sebastian; Maercker, Andreas (2016). Evidence for two different ICD-11 posttraumatic stress disorders in a community sample of adolescents and young adults. European Archives of Psychiatry and Clinical Neuroscience, 266(4):317-328.

Abstract

For the 11th revision of the International classification of diseases, a general category of posttraumatic stress disorders has been proposed with two distinct sibling disorders: posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD). General population data are examined on evidence for these two disorders. Data were drawn from a 10-year prospective longitudinal, epidemiological study with a representative community sample (N = 3021, 14-24 years at baseline) in Germany. Mixture modelling on latent classes was conducted in a subset of all reported episodes with exposure to interpersonal traumas. Associations between class membership, symptom criteria, and other mental disorders were investigated. Four distinctly interpretable latent classes were found. Class 1 episodes (N = 181) typically included core PTSD symptoms associated with strong impairment (OR 11.68; 95 % CI 4.54-30.05). 18.3 % of these episodes matched the criteria of ICD-11 PTSD. Class 2 episodes (N = 78) had a high probability of PTSD core symptoms and disturbances in self-organization and were associated with strong impairment (OR 38.47; 95 % CI 15.77-93.86). Half of them (49.4 %) matched the proposed ICD-11 criteria of CPTSD. Class 3 (N = 79) was typically characterized by episodes with disturbances in self-organization but a low probability of PTSD core symptoms and impairment. Class 4 (N = 633) was related to a relatively low probability of symptom reports. Membership in class 2 was associated with lower educational attainment, a lower social class, and more other mental disorders. Findings support the ICD-11 proposal to differentiate between PTSD and CPTSD. Further studies should extend exploration to other types of traumatic events in samples covering the full age range.
