Notes: Withdrawal = social withdrawal scale; Anx-Dep = anxiety-depression scale; Soc. Prob = social problems scale; Int. Prob = internalizing problems scale; YSR TOT = total problems scale of the YSR; GAF = Global Assessment of Functioning; DDF = difficulty describing feelings; DIF = difficulty identifying feelings; EOT = externally-oriented thinking; TAS TOT = total score of the TAS-20.
