  1. Note: Level of conduct problems was determined by the Revised Rutter Teacher conduct difficulties subscale (Hogg et al., 1997); ODD = Oppositional Defiant Disorder; ADHD = Attention Deficit and Hyperactive Disorder; ADHD, CD/ODD, Anxiety and Depression diagnoses were determined by diagnostic information contained in the participants files. Expressive language was determined by the Word Definition Test (WD-BASII) British Ability Scales II; SES (socioeconomic status) was determined by the Duncan's socioeconomic index (Hauser & Featherman, 1977); M: Mean, Mdn: Median; IQR = Interquartile Range; SD = Standard Deviation; Effects on CD diagnosis could not be calculated because no diagnoses were present in the control group; Medians in the same row that do not share subscripts differ at p < .05 in the Mann-Whitney U procedure.
