Objectives: Childhood Trauma Questionnaire-Short Form (CTQ-SF), a 28- item retrospective self-report questionnaire, is the most widely used measure to assess multiple dimensions of childhood trauma exposure (CTE). The CTQ-SF has been translated into different languages, but the Chinese version have not yet been studied. In this study, we intended to examine the reliability and factor structure of the Chinese version of the CTQ-SF (C-CTQ-SF).Methods: We administered the questionnaire of the C-CTQ-SF to 160 patients with substance use disorder. The internal consistency and test–retest reliability of the C-CTQ-SF at 2–3 weeks after initial assessment were evaluated using Cronbach’s α coeffi cients and intraclass correlation coeffi cients (ICCs). We also did confi rmatory factor analysis (CFA) and exploratory factor analysis (EFA), to test the factor structure of the C-CTQ-SF. Results: The C-CTQ-SF was found to have fair to adequate internal consistency (Cronbach’s α ranging from 0.574 to 0.895) and test–retest reliability (ICCs ranging from 0.674 to 0.852). The results of CFA showed relatively low factor loading for the physical neglect subscale. Subsequent EFA yielded a stable fi ve-factor structure, and some items had cross-loadings with more than one factor. Conclusion: Our results indicated that C-CTQ-SF has adequate reliability and a fi ve-factor solution, supporting the feasibility of using the C-CTQ-SF to assess CTE in patients with substance use disorders. Consisting with previous reports, the physical neglect subscale did not emerge as a stable factor.
