We evaluated inconsistencies in responses to questions about lifetime cocaine and marijuana use asked of nearly 10,000 respondents from the United States in the National Longitudinal Survey of Youth in 1984 and 1988. Our analyses showed that 14% of all responses on cocaine use and 17% of all responses on marijuana use were inconsistent in some way. The types of inconsistencies varied according to the substance; cocaine reports yielded more inconsistencies with regard to timing of first use, while for marijuana most of the inconsistencies were with respect to use disclosure. For both substances, lower level users were more likely to be inconsistent in their reports of drug use. Alternative methods for handling inconsistencies affected estimates of incidence and prevalence. Inconsistencies also varied according to respondent race/ethnicity. Implications of these findings for program evaluation are discussed.
我们评估了在1984年和1988年美国国家青年纵向调查中，针对近1万名来自美国的受访者所提出的关于终生使用可卡因和大麻情况的问题回答中的不一致性。我们的分析表明，所有关于可卡因使用的回答中有14%以及所有关于大麻使用的回答中有17%在某种程度上存在不一致。不一致的类型因物质而异；关于可卡因使用的报告在首次使用时间方面产生了更多不一致，而对于大麻，大多数不一致是关于使用情况的披露。对于这两种物质，低水平使用者在药物使用报告中更有可能出现不一致。处理不一致的替代方法影响了发病率和患病率的估计。不一致性也因受访者的种族/族裔而异。讨论了这些发现对项目评估的影响。
