IQ refers to full-scale IQ scores obtained from the WAIS-III or WISC-IV; PCL:YV Factor 1 and 2 scores refer to factor scores (i.e., Factor 1: interpersonal and affective psychopathic traits; Factor 2: lifestyle/behavioral and antisocial/developmental psychopathic traits) derived from the PCL:YV; TCL 2.0 total refers to the total trauma score obtained from the TCL 2.0; TCL PC1 and PC2 scores refer to component scores obtained from the TCL 2.0, with PC1 representing Experienced Trauma scores and PC2 representing Community Trauma scores; UES total refers to the total score derived from the Upsetting Events Survey. Significant effects (p < .05) based on a one-tailed statistical test are highlighted using asterisks (**)
