这项研究调查了全国青年纵向调查中终生大麻和可卡因使用的漏报。本研究将1988年提供的答复与1984年提供的答复进行比较，评估了两个漏报指标的流行率和相关性，包括拒绝使用和减少使用。在1988年的随访中，大麻和可卡因的低报率很高，1984年所有大麻使用者中有不到三分之一的人和1984年所有可卡因使用者中有三分之一以上的人的使用率下降。1988年，可卡因使用者中明显否认使用的比例几乎是大麻使用者的两倍;在随访中，近19%的可卡因使用者否认使用，而所有大麻使用者中有近12%否认使用。漏报的相关性因内容和漏报措施而异。最一致的相关性漏报的采访模式，种族/民族，和教育状况。那些通过电话采访的人，少数民族受访者和那些教育水平较低的人更有可能少报。在我们的分析中，种族/民族效应特别引人注目。在每一项漏报指标上，黑人受访者漏报的几率至少是白色/其他受访者的两倍。调查结果进行了比较与其他最近的研究报告不足，并在最近的物质使用流行率调查结果的背景下进行了讨论。
This study investigates underreporting of lifetime marijuana and cocaine use in the National Longitudinal Survey of Youth. Comparing responses provided in 1988 with responses provided in 1984, this study evaluates the prevalence and correlates of two indicators of underreporting, including use denial and use reduction. At follow-up in 1988, a high rate of underreporting was evident for both marijuana and cocaine, with rates of use reduction observed for just under one-third of all 1984 marijuana users and just over one-third of all 1984 cocaine users. Outright denial of use in 1988 was almost twice as prevalent among cocaine users as it was among marijuana users; nearly 19 percent of all cocaine users denied use at follow-up, compared with nearly 12 percent of all marijuana users. Correlates of underreporting varied by substance and by measure of underreporting. The most consistent correlates of underreporting were interview mode, race/ethnicity, and educational status. Those interviewed by telephone, minority respondents, and those with lower levels of education were more likely to underreport. Race/ethnicity effects were particularly striking in our analyses. Black respondents had at least twice the odds of underreporting compared with white/other respondents for every indicator of underreporting. Findings are compared with other recent research on underreporting and are discussed in the context of recent substance use prevalence findings.
