This study examined whether risks operate similarly in a justice sample. Suicidal behaviour & disorder were measured on the Diagnostic Interview Schedule for Children in 991 selected youths, & examined associations between demographic, disorder characteristics, & past attempts. Recent attempts were more common in girls, in those with depression or substance disorder, & in violent offenders. While more girls reported recent attempts regardless of depression, depressed boysÕ attempt risk was high as girlsÕ. Depression contributed more to attempt history than did substance disorder.
