Note. The Diagnostic Interview Schedule for Children (DISC) measure was count-based, so we report (a) Spearman’s correlation instead of Pearson’s correlation; (b) median instead of mean; and (c) range instead of standard deviation. BSI = Brief Symptom Inventory; MTFC = Multidimensional Treatment Foster Care.
