The Trauma Symptom Checklist–40 (TSC-40) is commonly used in clinical research to index history of childhood maltreatment and assess complex trauma symptomatology in adults. Yet the dimensional structure of this measure has not been examined. We examined the factor structure of the TSC-40 in a sample of 706 undergraduate students, measurement invariance of the TSC-40 across groups with or without a history of abuse-related and multiple trauma, and the association between the TSC-40 and other trauma indices. A higher order model of complex trauma symptomatology was optimal. The higher order model also demonstrated strong measurement invariance across participants with or without abuse-related and multiple trauma histories. The current findings support the dimensional structure of the TSC-40, as well as extending and revising its subscale composition. This study provided support for using the TSC-40 to measure trauma symptoms across groups exposed to different and multiple types of trauma and provided further evidence for the construct of complex trauma symptomatology.
