Hyper and hypo-activation affective dysregulation symptoms are integral in complex PTSD (CPTSD): Results from a non-clinical Israeli sample
  Objectives: The current study sought to further assess the nature of the Affect Dysregulation (AD) cluster of the ICD-11 proposal for Complex PTSD (CPTSD) in a non-clinical sample.

Methods: An online survey sample from Israel (n = 618) completed a disorder-specific measure (ITQ; International Trauma Questionnaire) of PTSD and CPTSD along with the Life Events Checklist and the World Health Organization Well-Being Index.

Results: Estimated prevalence rates of PTSD and CPTSD were 9.2% and 1.0%, respectively. Confirmatory factor analysis results indicated that AD symptoms are better conceived as two correlated dimensions of hyper- and hypo-activation symptoms. Latent class analysis results indicated that CPTSD was clearly distinguishable from PTSD. CPTSD class membership was associated with higher levels of traumatization and poorer psychological wellbeing scores.

Conclusions: Findings support the discriminant validity of the ICD-11 proposals for PTSD and CPTSD in a non-clinical sample using a disorder-specific measure. The results provide further evidence that the final symptom profile for CPTSD in ICD-11 should model the AD cluster using both hyper- and hypo-activation symptoms.
