• A case-history format was utilized to compare interrater agreement on childhood and adolescent psychiatric disorders, using DSM-II and DSM-III. The average interrater agreement was 57% for DSM-II and 54% for axis I (clinical psychiatric syndrome) of DSM-III. There was high agreement in both systems on cases of psychosis, conduct disorder, hyperactivity, and mental retardation, with DSM-III appearing slightly better. There was noteworthy interrater disagreement in both systems for "anxiety" disorders, complex cases, and in the subtyping of depression. Overall, the reliability of DSM-III appears to be good and is comparable with that of DSM-II and other classification systems of childhood psychiatric disorders.
