The present study assessed drug use and the validity of self-reports of substance use among help-seeking veterans referred to a specialty clinic for the assessment of posttraumatic stress disorder (PTSD). Patients (n = 341) were asked to provide a urine sample for use in drug screening as part of an evaluation of PTSD. Self-reports of substance use were compared with same-day supervised urine samples for 317 patients who volunteered to participate in a drug screening. Results suggested that self-reports were generally quite valid. Only 8% of the cases involved patients not reporting substance use detected by urine screens. A total of 42% of the participants were identified as using drugs of abuse (excluding alcohol) through self-report and urine drug screens. Among participants using drugs, PTSD diagnosis was significantly associated with greater marijuana and depressant use as compared with stimulant (cocaine and amphetamines) use.
本研究评估了转至一家专科诊所评估创伤后应激障碍（PTSD）的求助退伍军人的药物使用情况以及药物使用自我报告的有效性。作为PTSD评估的一部分，要求患者（n = 341）提供尿液样本用于药物筛查。将317名自愿参与药物筛查的患者的药物使用自我报告与同日监督下的尿液样本进行了比较。结果表明，自我报告总体上相当有效。只有8%的病例涉及未报告尿液筛查检测出的药物使用的患者。通过自我报告和尿液药物筛查，总共42%的参与者被确定为使用滥用药物（不包括酒精）。在使用药物的参与者中，与使用兴奋剂（可卡因和苯丙胺）相比，PTSD诊断与更多使用大麻和抑制剂显著相关。
