Abstract
Objective: This study assesses the Adolescent Domain Screening Inventory (ADSI) to identify adolescents at high risk of substance use. Method: The sampling frame consisted of 26,781 surveys, and a secondary analysis was conducted. A random 25% sample was used, leaving 6,661 cases. Binary logistic regressions were run to determine the predictive validity of the total ADSI and its 4 domains. Results: The ADSI correctly predicted high risk 93% of the time and problematic use 84.3% of the time. Conclusions: The results indicate the ADSI should be considered for use to assess adolescents for high risk status for substance use, or to identify those already engaged in substance use.
Notes
Note. High Risk: Specificity = 5,133/(5,133 + 194) = 96.4%, Sensitivity = 1,031/(269 + 1,031) = 79.3%, False Positive = 194/(194 + 1,031) = 16%, False Negative = 269/(5,133 + 269) = 5%. Problem Use: Specificity = 4,586/(4,586 + 306) = 93.7%, Sensitivity = 643/(668 + 643) = 49%, False Positive = 306/(306 + 642) = 32%, False Negative = 668/(4,586 + 668) = 13%.
Note. High Risk: Cox and Snell R 2 = .484, Nagelkerke R 2 = .770. Problem Use: Cox and Snell R 2 = .295, Nagelkerke R 2 = .458. Dependent reference categories: Low Risk, No Problem Use.
Note. All relationships are significant at the p < .001 level.
