Notes: Adolescent-reported depressive and conduct disorder symptoms are shown below the diagonal. Parental ratings of adolescent depressive and conduct disorder symptoms are shown above the diagonal. Sample sizes range from 373 to 512 for adolescent ratings and from 370 to 517 for parental ratings, depending on what grades were correlated. Gender (1 = male, 2 = female); DEP = depression symptom count from the Diagnostic Interview Schedule for Children (DISC); CD = conduct disorder symptom count from DISC; ALC = adolescent-report of whether he or she used alcohol in the past 6 months (yes/no).

^aCorrelation could not be computed because sixth-grade alcohol use was 0 for all respondents available for the correlation.
