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.
