OBJECTIVE: To determine the accuracy of the CRAFFT substance abuse screening test. DESIGN: Criterion standard validation study comparing the score on the 6-item CRAFFT test with screening categories determined by a concurrently administered substance-use problem scale and a structured psychiatric diagnostic interview. Screening categories were "any problem" (ie, problem use, abuse, or @entity734 ), " @entity74 " (ie, @entity734 ), and " @entity734 ." SETTING: A large, hospital-based adolescent clinic. @entity1 : @entity1 aged 14 to 18 years arriving for routine health care. MAIN OUTCOME MEASURES: The CRAFFT receiver operating characteristic curve, sensitivity, specificity, positive predictive value, and negative predictive value. RESULTS: Of the 538 @entity1 , 68.4% were female, and 75.8% were from racial and ethnic minority groups. Diagnostic classifications for substance use during the past 12 months were no use (49.6%), occasional use (23.6%), problem use (10.6%), abuse (9.5%), and @entity734 (6.7%). Classifications were strongly correlated with the CRAFFT score (Spearman rho, 0.72; P<.001). A CRAFFT score of 2 or higher was optimal for identifying any problem (sensitivity, 0.76; specificity, 0.94; positive predictive value, 0.83; and negative predictive value, 0.91), @entity74 (sensitivity, 0.80; specificity, 0.86; positive predictive value, 0.53; and negative predictive value, 0.96) and @entity734 (sensitivity, 0.92; specificity, 0.80; positive predictive value, 0.25; and negative predictive value 0.99). Approximately one fourth of @entity1 had a CRAFFT score of 2 or higher. Validity was not significantly affected by age, sex, or race. CONCLUSION: The CRAFFT test is a valid means of screening adolescents for substance-related problems and disorders, which may be common in some general clinic populations.
