Predictors of misreporting cigarette smoking initiation among adolescents.

This study examines the prevalence of invalid reports of cigarette smoking initiation among adolescents (i.e., reporting cigarette smoking at one time point and denying ever trying cigarettes at a subsequent time point) and the association of misreports with scores on other problem-prone variables. Misreports did not vary as a function of item complexity and did not reflect careless responding. In the seventh grade, misreporters' scores on the problem-prone variables were higher than those of nonsmokers and lower than those of smokers. In contrast, when measured in the eighth grade, misreporters' scores did not differ from those of nonsmokers. Misreporters did show a greater decrease in intentions to smoke, alcohol use, and number of friends who smoke compared to nonsmokers and consistent smokers. Explanations for these findings are discussed.
