CD = conduct disorder patients; TD = typically developing peers; ICU = parent-reported Inventory of Callous-Unemotional Traits total scores; SASC = parent-reported Social Anxiety Scale for Children total scores; CBCL = parent-reported Child Behaviour Checklist total scores, scores on the CBCL-internalising (INT) and -externalising (EXT) subscales
