We examined follow-up data from surveys in 1988, 1992 and 1994 in order to estimate the prevalence and explore the correlates of retest artifact (denial) of drug use among National Longitudinal Survey of Youth respondents who disclosed lifetime cocaine or marijuana use in 1984. In the cocaine use cohort, 42% denied lifetime cocaine use during at least one follow-up wave. In the marijuana use cohort, about 29% denied lifetime marijuana use during at least one follow-up wave. Denial either leveled off (cocaine) or diminished (marijuana) between the second and third follow-up interviews. The most consistent predictors of denial in both longitudinal and cross-sectional models and across substances were race/ethnicity (black informants had increased rates of denial) and marital status (married respondents had increased rates of denial). Other predictors of denial included interviewer characteristics (social attribution), interview mode, and drug salience. The findings with respect to marijuana reporting trends parallel increased willingness of public officials to retrospectively disclose this behavior in the popular press.

We examined three follow-up waves of data in order to estimate the prevalence and explore the correlates of retest artifact (denial) of drug use among NLSY respondents who disclosed lifetime cocaine and marijuana use in 1984. In the cocaine use cohort, 42% denied lifetime drug use during at least one follow-up wave. In the marijuana use cohort, about 29% denied lifetime drug use during at least one follow-up wave. (mixed model) and cross sectional logistic regression models were estimated to evaluate the correlates of this phenomenon. Although we hypothesized linear time effects, we found that denial either leveled off (cocaine) or diminished (marijuana) between the second and third interviews. Longitudinal models suggested that individuals were fairly consistent with respect to disclosure propensities. The most consistent predictors of denial in both longitudinal and cross sectional models and across substances were race and marital status. Other predictors of denial included interviewer characteristics (social attribution), interview mode, and drug salience. Interpretation of findings with respect to time are made in light of recent shifts in drug disclosure norms. Implications for theories of survey reporting, for research design, and for the interpretation and analysis of longitudinal drug use data are also discussed.
