Diminished Lifetime Substance Use Over Time: A Validated Inquiry Into Differential Underreporting Public Opinion Quarterly 58,1 (Spring 1994): 96-123. Also: http://poq.oxfordjournals.org/content/58/1/96.abstract Cohort(s): NLSY79 Publisher: University of Chicago Press Keyword(s): Drug Use; Educational Attainment; Interviewing Method; Minorities; Racial Differences; Self-Reporting; Substance Use; Underreporting This study investigated underreporting of lifetime marijuana and cocaine use in the National Longitudinal Survey of Youth. Unlike previous studies of substance use underreporting, this study validated reports by using responses provided at the initial interview as criteria. Comparing responses provided in 1988 with responses provided in 1984, this study evaluated 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% of all cocaine users denied use at follow-up, compared to nearly 12% 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 to white/other respondents for every indicator of underreporting. Findings are compared to other recent research on underreporting and are discussed in the context of recent substance use prevalence findings. |
