Abstract

Objective

Support for ICD‐11 post‐traumatic stress disorder (PTSD) and complex PTSD (CPTSD) is growing; however, few studies include refugees or examine the clinical utility of PTSD/CPTSD classifications. This study sought to provide the first evaluations of (i) the factor structure of ICD‐11 PTSD/CPTSD amongst refugees in the Middle East; and (ii) the clinical utility of the International Trauma Questionnaire (ITQ) to identify PTSD/CPTSD in a humanitarian context.
Method

Participants were 112 treatment‐seeking Syrian refugees living in Lebanon. Factorial validity was assessed using confirmatory factor analysis (CFA) based on responses to the ITQ. Clinical utility of the ITQ was assessed through semi‐structured interviews with six Lebanese psychotherapists.
Results

Complex PTSD (36.1%) was more common than PTSD (25.2%), and no sex or age differences were observed at the prevalence or symptomatic levels. CFA results supported a two‐factor higher‐order model consistent with ICD‐11 PTSD/CPTSD. Qualitative findings indicated that the ITQ is generally positively regarded, with some limitations and suggested modifications noted.
Conclusion

This is the first study to support the ICD‐11 PTSD/CPTSD amongst refugees in the Middle East and the clinical utility of the ITQ in a humanitarian context. Findings support the growing evidence for the cross‐cultural applicability of ICD‐11 PTSD/CPTSD.
