Axis I disorders other than conduct disorder were assessed using a Norwegian computerized version of the Munich-Composite International Diagnostic Interview (M-CIDI) (30)—a comprehensive structured diagnostic interview assessing DSM-IV axis I disorders (1) that has been shown to have good test-retest and interrater reliability (31–33). Both the paper-and-pencil version and the computerized version of the M-CIDI have previously been used in Norway (34, 35).
