Abstract

Background. Two stress related disorders have been proposed for inclusion in the revised ICD11:
Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD). The International
Trauma Questionnaire (ITQ) is a bespoke measure of PTSD and CPTSD, and has been widely
used in English speaking countries. Objective. The primary aim of this study was to develop a
Chinese version of the ITQ and assess its content, construct, and concurrent validity. Methods.
Six mental health practitioners and experts rated the Chinese translated and back-translated items
to assess content validity. A sample of 423 Chinese young adults completed the ITQ, the WHO
Adverse Childhood Experiences International Questionnaire, and the Hospital Anxiety and
Depression Scale. Among them, 31 participants also completed the English and Chinese versions
of the ITQ administered in random order at retest. Four alternative confirmatory factor analysis
models were tested using data from participants who reported at least one adverse childhood
experience (ACE; N=314). Results. The Chinese ITQ received excellent ratings on relevance
and appropriateness. Test-retest reliability and semantic equivalence across English and Chinese
versions were acceptable. The correlated first-order six-factor model and a second-order twofactor
(PTSD and DSO) both provided acceptable model fit. The six ITQ symptoms clusters
were all significantly correlated with anxiety, depression, and number of ACEs. Conclusions.
The Chinese ITQ generates scores with acceptable psychometric properties and provides
evidence for including PTSD and CPTSD as separate diagnoses in ICD-11.
