Validation of post-traumatic stress disorder (PTSD) and complex TPSD using the International Trauma Questionnaire
A study using a newly developed, disorder-specific measure of PTSD and CPTSD called the International Trauma Questionnaire (ITQ).
Article Abstract
“Objective: The 11th version of the International Classification of Diseases (ICD-11) has proposed two related trauma diagnoses: Post-traumatic stress disorder (PTSD) and Complex PTSD (CPTSD). Using a newly developed, disorder-specific measure of PTSD and CPTSD called the International Trauma Questionnaire (ITQ) the current study will (i) assess the factorial validity of ICD-11 PTSD and CPTSD; (ii) provide the first test of the discriminant validity of these constructs; and (iii) provide the first comparison of ICD-11, and Diagnostic and Statistical Manual, Fifth Edition (DSM-5), PTSD diagnostic rates using disorder-specific measures.
Method: ICD-11 and DSM-5 PTSD-specific measures were completed by a British clinical sample of trauma-exposed patients (N = 171). The structure and validity of ICD-11 PTSD and CPTSD were assessed by means of factor analysis and assessing relationships with criterion variables.
Results: Diagnostic rates under ICD-11 were significantly lower than those under DSM-5. A two-factor second-order model reflecting the distinction between PTSD and CPTSD best represented the data from the ITQ; and the PTSD and CPTSD factors differentially predicted multiple psychological variables.
Conclusion: The factorial and discriminant validity of ICD-11 PTSD and CPTSD was supported, and ICD-11 produces fewer diagnostic cases than DSM-5.”
