Table 1 shows the correlations across the variables, with the adult sample shown below the diagonal and the adolescent sample above the diagonal. The pattern of correlations is similar in the adolescent and adult samples; however, the Achenbach Externalizing scale is more strongly correlated with conduct disorder symptoms in adolescents as compared with young adults and less so with alcohol-dependence symptoms in adolescents. The BIS is more strongly correlated with SSS in young adulthood than in adolescence. Extraversion scores showed the lowest correlations with the other measures in both samples.
