In memoriam of Dale Kulp. Adapted from the source document.

This article reports results from a student survey fielded using an experimental design with 14 Kentucky school districts. Seven of the 14 districts were randomly assigned to implement the survey with active consent procedures; the other seven districts implemented the survey with passive consent procedures. We used our experimental design to investigate the impact of consent procedures on (a) participation rates, (b) demographic characteristic of the survey samples, and (c) estimates of alcohol, tobacco, and other drugs (ATOD) use. We found that the use of active consent procedures resulted in reduced response rates, underrepresentation of male students and older students, and lower lifetime and past 30-day prevalence rates for most drugs and for most antisocial behaviors. Methodological implications of these findings are discussed along with directions for further research.

In September 2008, the AAPOR Executive Council established an Opt-In Online Panel Task Force and charges it with "reviewing the current empirical findings related to opt-in online panels utilized for data collection and developing recommendations for AAPOR members." The council further specified that the charge did not include development of best practices, but rather would "provide key information and recommendations about whether and when opt-in panels might be best utilized and how best to judge their quality." The task force was formed in October 2008. This is its report. Adapted from the source document.
