创伤后应激障碍（PTSD）在寻求治疗的药物滥用者中很常见。尽管这些并发症的患病率很高，但很少有PTSD筛查工具在物质使用障碍（SUD）人群中识别PTSD的效用进行了评估。本研究采用事件影响量表（IES-R）对124名物质依赖者进行心理测量学研究。所有参与者都有DSM-IV标准A创伤事件的历史，71人符合PTSD的诊断标准。与没有PTSD的物质依赖个体相比，患有PTSD共病的参与者报告了更多的焦虑，抑郁和PTSD症状。在物质依赖性样本中确立了IES-R的可接受内部一致性和收敛效度。诊断有效性检查表明，对于物质使用人群，最佳临界值为22，从而获得足够的分类准确性、灵敏度和特异性。(c)2008爱思唯尔有限公司保留所有权利。
Posttraumatic stress disorder (PTSD) is common among treatment-seeking substance abusers. Despite the high prevalence of these co-occurring conditions, few PTSD screening tools have been evaluated for their utility in identifying PTSD in substance use disorder (SUD) populations. The present study evaluated the psychometric properties of the Impact of Event Scale-Revised (IES-R) in a sample of 124 substance dependent individuals. All participants had a history of a DSM-IV Criterion A traumatic event, and 71 individuals met diagnostic criteria for PTSD. Participants with comorbid PTSD reported significantly more symptoms of anxiety, depression, and PTSD compared to substance dependent individuals without PTSD. Acceptable internal consistency and convergent validity of the IES-R were established among a Substance dependent sample. Examination of diagnostic effectiveness suggested a cutoff value of 22 as optimal for a substance using population, resulting in adequate classification accuracy, sensitivity, and specificity.
