Validation of the "problematic use of narcotics" (PUN) screening test for drug using adolescents.
The aim of the study was to examine psychometric properties of the PUN screening test concerning illicit drug problem use by adolescents. The criterion standard for the test's validity was a diagnostic interview conducted by trained specialists. Respondents were reached by snowball sampling in 58 randomly chosen Polish local communities. A total of 1344 adolescent (37% female) aged 13 to 18 years, who used any illicit drug at least once in the past 12 months, participated. The majority (89%) had no contacts with any drug therapy facilities. 41% were diagnosed as occasional drug users and 59% as problematic users or dependents. Logistic regression analysis showed that 10 out of the basic set of 25 test items were most powerful in differentiating occasional and problematic users. A test score of 2 or higher was optimal for identifying problem drug use (sensitivity: 0.88, specificity: 0.79, PPV: 0.86, NPV: 0.81). Validity was not affected by age or sex. These results confirmed the PUN test potential as a brief screening tool.
