The purpose of this study was to examine the utility of the Personal Experience Inventory (PEI) as a measure of change in adolescent drug misuse. One year test-retest reliability of the PEI Problem Severity Scales was measured in a sample of drug-misusing adolescents who did not receive treatment during the 1-year test-retest interval (n = 37). The five PEI Problem Severity Scales demonstrated satisfactory 1 year temporal stability coefficients, ranging from .86 to .89. The utility of the PEI as a measure of change was demonstrated by using the 1-year test-retest reliability data to measure both statistically significant and clinically significant change between admission and 1-year follow-up in a sample of drug-misusing adolescents who received treatment (n = 45). The PEI was useful in identifying which treatment clients exhibited statistically significant improvement, statistically significant deterioration, and no reliable change.

    ABSTRACT: The objective of this study was to measure the sensitivity and specificity of the RAFFT, a screening instrument for problematic adolescent substance use. Two hundred and twenty-six adolescent patients, aged 13 to 18, who were referred to an emergency room or an ambulatory evaluation clinic were included. Patients answered the five questions of the RAFFT before a comprehensive psychiatric assessment was completed. Diagnoses were made according to DSM-IV. The best results were obtained with two positive answers on the RAFFT: a sensitivity of 89% and a specificity of 69% in the screening for substance abuse or dependence. The RAFFT performed well in this highly selected patient population.

    ABSTRACT: To determine the internal consistency and 1-week test-retest reliability of the Simple Screening Instrument for Alcohol and Other Drug Abuse (SSI-AOD), the CAGE-AA (CAGE questions adapted for adolescents), and 4 modified items from the Drug and Alcohol Problem QuickScreen (DAP-4) among adolescents. Fifteen- to 18-year-old medical patients (n = 173) completed screening tests during a routine medical visit and then again 1 week later. Internal consistency for each test and retest was calculated using Cronbach's alpha, and 1-week test-retest reliability was calculated by using Winer's unbiased estimate of the intraclass correlation coefficient (r). The SSI-AOD has good internal consistency (alpha =.83) and the CAGE-AA questions acceptable internal consistency (alpha =.60). Alpha varied with gender and race, and item analysis indicated the CAGE-AA test could be improved. As expected, the DAP-4 had a lower alpha score (.46). All screening instruments studied had high 1-week test-retest reliabilities (range r =.82-.90). The SSI-AOD is a reliable substance abuse screening instrument among adolescent medical patients. The CAGE-AA questions must be further revised and tested before their use can be recommended. The DAP-4 questions are likely measuring different, but important, constructs.
