“…The Trauma Symptom Checklist–40 (TSC-40; Briere & Runtz, 1989; Elliott & Briere, 1992) was originally developed to measure the complexity of the long-term impact of childhood trauma in adulthood and has since been used to assess trauma-related symptoms associated with child and adult traumas and victimization. It remains a popular research tool, with both clinical (e.g., Briere & Runtz, 1989; Cinamon, Muller, & Rosenkranz, 2014; Harris et al, 2016; Murphy, Elklit, Murphy, Hyland, & Shevlin, 2017; Pec, Bob, & Raboch, 2014) and nonclinical samples (e.g., Clemmons, Walsh, DiLillo, & Messman-Moore, 2007; Elliott & Briere, 1992; Fortier et al, 2009; Rosenthal & Freyd, 2017; Schaefer & Nooner, 2017; Smith & Freyd, 2013), highlighting the prevalence of trauma-related symptoms in the general population (Briere & Elliott, 2003; Elliott & Briere, 1992). However, the dimensional structure of the measure as well as its measurement invariance across groups exposed to different trauma types is yet to be established.…”
