The present study examined the association between psychopathology and substance abuse using the Youth Self-Report scale. To ensure the psychometric properties of the YSR scale, its factor structure derived by Achenbach was evaluated. The data obtained from a three year follow-up study of adolescents hospitalized for psychiatric treatment was used to test the hypotheses set forth in the study. The data was collected using a nonexperimental research design at three points in time. In the study, time 1 data was utilized for generating the initial findings, and time 2 for cross validation. Time 3 data was not used because the sample size was too small. The study confirmed part of Achenbach's findings in that four first order factors remained unidimensional; they are Somatic Complaints, Anxious/Depressed, Thought Problems, and Attention Problems. However, subdimensions were further derived for Social Problems, Delinquent Behaviors, and Aggressive Behaviors. Additionally, Social Problems, Thought Problems, and Attention Problems were found cross loaded on both Internalizing and Externalizing scales. The results of the tests for the structural models revealed that the measures of psychopathology explained significant amount of variance in substance abuse for the total sample and for the girls (29% and 36%, respectively), whereas explained variance was only 10% for the boys. Externalizing had significant effect on substance abuse; among the first order factors, Delinquent Behaviors, Aggressive Behaviors, Attention Problem were the three predominant predictors of substance abuseThe results of discriminant function analyses demonstrated the usefulness of the YSR in classifying substance abusers among adolescents with psychiatric disorders. For the girls, it enhanced the classification accuracy 34 percent greater than that achieved by chance; whereas, for the boys, for boys, 26 percent greater than chance. The study found that the gender differences were not on the types of p (open full item for complete abstract)
