Note: PEP = pre-ejection period; PEP-R = PEP reactivity; GM = grandiose-manipulative; CU = callous-unemotional; DI = daring-impulsive; SA = Social adversity. Hierarchical regression analyses were conducted across multiple imputations. Pooled coefficient statistics are given for the imputed data. Analyses were re-run using only cases in the original dataset and findings remained unchanged. The displayed statistics of the variables at Steps 1 and 2 represent the values after interaction terms were included at Step 3 in the final model.
