目得：了解自我报告最近的药物使用的有效性，在男性与男性发生性关系（MSM）。方法：我们获得了概率样本的芝加哥男性与男性发生性关系（MSM; n = 216）和管理尿液和唾液药物测试后，自我管理的采访。分析研究了药物测试的参与，自我报告的过去一个月药物使用和药物测试结果之间的一致性，漏报的相关性，以及药物测试与自我报告在识别最近大麻和可卡因使用方面的相对效用。对于大麻和可卡因，研究结果进行了比较，从一般人群样本的男性（n = 241）。结果：超过四分之三的参与者在这两个样本中提供至少一个标本进行药物测试。两个样本中的自我报告都显示出与大麻药物测试的高度一致性，但与可卡因无关。可卡因使用报告的敏感性为60%的男男性接触者样本和40%的一般人群男性。大麻、可卡因、3，4亚甲二氧基甲基苯丙胺（即，MDMA，“狂喜”）和甲基苯丙胺表明，MSM的自我报告具有高度的有效性。低报是一个相关的社会阶层（教育，收入和就业）在一般人群中，但不是在男男性接触者样本。药物检测的效用是依赖于社会阶层在一般人群sample.CONCLUSIONS：药物检测是可行的药物使用的流行病学调查。男男性行为者的自我报告至少与一般男性人口样本提供的报告一样有效。在一些情况下（例如，可卡因使用），它们实际上可能具有更高的质量。虽然研究结果支持MSM药物使用的流行病学研究的优点，完全依赖于自我报告，药物测试可能有助于澄清俱乐部药物摄入模式。Ann Epidemiol 2008;18：752-759.

PURPOSE: To understand the validity of self-reported recent drug use in men who have sex with men (MSM).METHODS: We obtained a probability sample of Chicago men who have sex with men (MSM; n = 216) and administered urine and saliva drug testing after a self-administered interview. Analyses examined participation in drug testing, the agreement between self-reported past month drug use and drug test results, correlates of underreporting, and the relative utility of drug testing versus self-reports in identifying recent marijuana and cocaine use. For marijuana and cocaine, findings were compared with those obtained from a general population sample of men (n = 241).RESULTS: More than three quarters of the participants in both samples provided at least one specimen for drug testing. Self reports in both samples showed a high degree of correspondence with drug tests for marijuana but not for cocaine. Sensitivity for cocaine use reporting was 60% for the MSM sample and 40% for the general-population men. Conditional kappa and sensitivity statistics for marijuana, cocaine, 3,4 methylenedioxymethamphetamine (i.e., MDMA, "ecstacy"), and methamphetamine suggested that self reports among MSM are provided with a high degree of validity. Underreporting was a correlate of social class (education, income, and employment) in the general population but not in the MSM sample. The utility of drug testing was dependent on social class in the general population sample.CONCLUSIONS: Drug testing is feasible in epidemiological surveys of drug use. Self reports among MSM are at least as valid as those provided by a general population sample of men. In some instances (e.g., cocaine use), they may actually be of higher quality. Although the findings support the merit of epidemiological studies of MSM drug use that have relied completely on self-reporting, drug tests may be useful for clarifying club drug ingestion patterns.
