Questions arising from the application of the ICD-11 diagnoses of complex post traumatic stress disorder and personality disorder.

There is an overlap between the International Classification of Diseases for Mortality and Morbidity Statistics- 11th Revision (ICD-11) diagnoses of complex post-traumatic stress disorder (CPTSD) and personality disorder. When the latter is comorbid with post-traumatic stress disorder (PTSD), this may allow for a false positive CPTSD diagnosis. This fact has both clinical implications and throws into relief theoretical questions about the ontology of trauma and personality disorder-related pathology. These questions are presented as a call for further research.
