Subst Use Misuse. 2018 Aug 24;53(10):1756-1761. doi: 10.1080/10826084.2018.1432646. Epub 2018 Feb 8.
Problems with self-reported drug use include difficulties with recall and recognition as well as the desire to respond to questions in a socially desirable manner. Various methods have been developed to improve and/or validate estimates based on direct questioning of individuals regarding their substance use. For this study, we were interested in validating self-reported use of: 1) tobacco, 2) marijuana, and 3) other substances (i.e., heroin, cocaine, opiates, oxycodone, benzodiazepines, methamphetamine, phencyclidine, and barbiturates) employing urinalysis among inmates who participated in a randomized controlled trial of a smoking abstinence intervention in a tobacco-free prison located in the northeastern United States.
Two-hundred and seven men and women with a mean age of 34.9 (standard deviation = 9.0) completed questions regarding their substance use on a 7-day Timeline Follow-Back and provided urine specimens three weeks following prison release.
Self-reported tobacco and marijuana use were highly consistent with urine drug testing in terms of overall agreement and Kappa (93.7% and.804 for tobacco, respectively; and 90.3% and.804 for marijuana, respectively); however, consistency was much lower for other drug use grouped together (62.7% and.270).
Although some former inmates may not accurately report substance use, our findings indicate that they are in the minority, suggesting that self-report is valid for tobacco and marijuana use but much less so for other drugs grouped together. Future research should be conducted with a larger and more diverse sample of former inmates to establish the generalizability of our findings from this study.
自我报告的药物使用问题包括回忆和识别困难，以及希望以社会认可的方式回答问题。已经开发了各种方法来改进和/或验证基于直接询问个人物质使用情况的估计。在本研究中，我们有兴趣验证自我报告使用的：1）烟草，2）大麻，3）其他物质（即海洛因、可卡因、鸦片制剂、羟考酮、苯二氮卓类、甲基苯丙胺、苯环利定和巴比妥类），在参与美国东北部一所无烟监狱戒烟干预随机对照试验的囚犯中采用尿液分析进行验证。
207名平均年龄为34.9岁（标准差 = 9.0）的男性和女性在7天时间线追溯中完成了关于他们物质使用的问题，并在出狱三周后提供了尿液样本。
自我报告的烟草和大麻使用在总体一致性和卡帕值方面与尿液药物检测高度一致（烟草分别为93.7%和0.804；大麻分别为90.3%和0.804）；然而，其他药物使用合并在一起的一致性要低得多（62.7%和0.270）。
虽然一些前囚犯可能没有准确报告物质使用情况，但我们的研究结果表明他们是少数，这表明自我报告对于烟草和大麻使用是有效的，但对于其他合并在一起的药物则有效性低得多。未来的研究应该对更大、更多样化的前囚犯样本进行，以确定我们这项研究结果的普遍性。
