reports, whether each respondent had a history of each disorder prior to occurrence of the randomly selected TE. DSM-IV organic exclusion rules and diagnostic hierarchy rules were used (other than ODD, which was defined with or without CD, and substance abuse, which was defined with or without dependence). As detailed elsewhere (Haro et al. 2006), generally good concordance was found between these CIDI diagnoses and blinded clinical diagnoses based on SCID clinical reappraisal interviews (First et al. 1994). Missing symptom reports, which were rare, were coded conservatively as the symptoms being absent. Missing information on AOO, which was rare, was imputed using regression-based imputation.
