What's in a Name? Do PTSD and Complex PTSD Diagnoses Predict Differences in Course and Outcome of Integrated Addiction and Trauma Focused Treatment?
In the ICD-11 post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD) are distinguished. CPTSD is associated with early childhood traumatization and more severe symptom patterns. Research thus far confirms that PTSD and CPTSD are two related but different concepts, but it's still unclear what the clinical relevance of this differentiation is. In addiction care approximately one out of three patients suffer from (C)PTSD. It's unclear if in patients with a substance use disorder (SUD) comorbid CPTSD results in poorer treatment outcomes compared to comorbid PTSD.
