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-IV diagnosis of cocaine dependence.
Cross-sectional survey.
Sydney, Australia.
One hundred and forty-two cocaine users.
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).
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).
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 CIDI.
本研究旨在评估依赖严重程度量表（SDS）作为可卡因依赖诊断指标的有效性，并确定能最佳区分有无DSM-IV可卡因依赖诊断的临界分数。
横断面调查。
澳大利亚悉尼。
142名可卡因使用者。
通过ROC分析，以综合国际诊断访谈（CIDI）测量的DSM-IV可卡因依赖诊断为对照，评估SDS的诊断性能。
ROC分析显示，SDS是一种用于测量可卡因依赖的具有高诊断效用的测试。发现SDS上能最佳区分有无DSM-IV可卡因依赖诊断的临界点为3（即分数为3或更高）。
本研究从统计学上验证了SDS作为可卡因依赖诊断指标的效用，并确定了合适的临界点。推荐将SDS作为可卡因依赖的简短筛查工具，可与更全面的测量方法（如CIDI）一起使用。
