A Comparison of Confidential versus Anonymous Survey Procedures: Effects on Reporting of Drug Use and Related Attitudes and Beliefs in a National Study of Students

This study presents a comparison of reporting of drug use and related attitudes and beliefs by national samples of eighth and tenth grade students under two different modes of administration conditions: confidential and anonymous. The results show that there were clearly no differences between the conditions in tenth graders' reports of drug use and related attitudes and beliefs. With eighth graders, the results show, at most, only a very modest mode of administration effect and quite possibly no effect at all. The results are reassuring to researchers who conduct surveys of drug use and related attitudes and beliefs among secondary school students.
