– = data not applicable. CU = Callous-Unemotional. The Bonferroni procedure was used to hold the familywise (FW) Type 1 error rate to the same as that for the Total Scale, p_FW=0.05; the Type 1 error rate per individual test was set at p_T=p_FW/28=0.0018. p_FW is based on the familywise Type 1 error rate; p_T is based on the Type 1 error rate per measurement procedure test.

^*p_FW<0.05; p_T< 0.0018. Correlation coefficients in bold denote relationship significant at p<0.05
