Our aim was to further assess the Severity of Dependence Scale (SDS) validity and to identify the cut-off score for a DSM-IV diagnosis of heroin and cocaine dependence through a cross-sectional survey in Barcelona, Spain.
The Psychiatric Research Interview for Substance and Mental Disorders (PRISM) was used as the gold standard. 146 young (18-30 years old) heroin users were recruited from outside the healthcare context, 135 of whom were also current cocaine users. SDS scores were correlated to quantity, frequency and length of drug use.
The SDS cut-off point at which there was optimal discrimination of a DSM-IV diagnosis presence was found to be 3 (i.e., a score of 3 or more) for heroin dependence and 4 for cocaine dependence.
The study gives further support to SDS dimensional properties and to its validity for rapid assessment of current heroin and cocaine dependence.
我们的目的是通过在西班牙巴塞罗那进行的一项横断面调查，进一步评估依赖严重程度量表（SDS）的有效性，并确定用于《精神疾病诊断与统计手册》第四版（DSM-IV）中对海洛因和可卡因依赖进行诊断的临界分数。
物质与精神障碍的精神病学研究访谈（PRISM）被用作金标准。从医疗环境之外招募了146名年轻（18至30岁）海洛因使用者，其中135人同时也是当前的可卡因使用者。SDS分数与药物使用的数量、频率和时长相关。
发现对于海洛因依赖，能最佳区分DSM-IV诊断存在与否的SDS临界值为3（即分数为3或更高），对于可卡因依赖则为4。
该研究进一步支持了SDS的维度特性及其在快速评估当前海洛因和可卡因依赖方面的有效性。
