ENGLISH :
Aim. The study aimed to assess the efficacy of the Severity of Dependence Scale (SDS) as a diagnostic measure of cocaine dependence and determine the cut-off score that best discriminates between the presence and absence of a DSM-lV diagnosis of cocaine dependence. Design. Cross-sectional survey. Setting. Sydney, Australia. Participants. One hundred and forty-two cocaine users. Measurements. The diagnostic performance of the SDS was measured via ROC analysis against DSM-IV diagnoses of cocaine dependence, as measured by the Composite International Diagnostic Interview (CIDI). Findings. ROC analysis revealed the SDS to be a test of' high diagnostic utility for the measurement of cocaine dependence. The cut-off point on the SDS at which there is optimal discrimination between the presence and absence of' a DSM-IV diagnosis of cocaine dependence was found to be 3 (i.e. a score of 3 or more). Conclusions. The study statistically validated the utility of the SDS as a diagnostic measure of cocaine dependence and has determined an appropriate cut-off point. The SDS is recommended as a brief screening instrument for cocaine dependence that can be used in addition to more comprehensive measures, such as the CID1. (Author' s abstract)
