The International Classification of Diseases, 11th edition (ICD-11) includes a revision of posttraumatic stress disorder (PTSD) and a new “sibling” diagnosis to PTSD, complex PTSD (CPTSD).
Studies have found issues with the old diagnostic demarcation of complex posttraumatic symptoms
and evidence in favor of the two new diagnoses in the ICD-11 is accumulating. At this point, construct
and discriminant validity of ICD-11 PTSD and CPTSD have been demonstrated in multiple studies
from around the world. However, few studies have investigated the different clinical features of ICD11 PTSD and CPTSD. For instance, unique personality traits and functioning has been acknowledged
in the study of psychopathology and shared personality traits have been found to account for cooccurrence between disorders. However, the investigation of such features in relation to ICD-11
PTSD and CPTSD have not been examined. Furthermore, prior research has documented overlaps in
symptoms between dissociation and PTSD. Despite such evidence, the investigation of the
relationship between ICD-11 PTSD/CPTSD and dissociation has not gained much interest yet.
