Note: Trauma = Total Trauma Index, calculated by summing the standardized composites of the sexual abuse and other traumatic events scale and the modified CTS scale; PEP bl, prep, speech, math = pre-ejection period at baseline rest and at the first minutes of speech preparation, speech, and math during GSST; zCO dprep, dspeech, dmath = change in cardiac output standard deviation units from baseline rest to the first minutes of speech preparation, speech, and math during GSST; YSR int = Youth Self Report internalizing scale; YSR ext = Youth Self Report externalizing scale; CBCL int = Child Behavior Checklist internalizing scale; CBCL ext = Child Behavior Checklist externalizing scale.
