Validity of the Survey of Health and Internet and Knowledge Networks Panel and Sampling. Stanford, CA.: Stanford University; 2003. 1 1. Introduction Our study was conducted using an internet-based survey methodology that may be unfamiliar to reviewers. In this document, we address potential questions reviewers may have. In particular, we provide more detailed information about Knowledge Networks (KN), the survey research firm conducting the survey, the techniques used in our survey and results of analyses performed by KN and other researchers, including ourselves, regarding the validity of the methodology. 2. Previous Publications Using the KN Panel Perhaps the strongest generalized endorsement of surveys conducted using the KN panel is that the panel is increasingly used by top researchers in a range of fields, including health care, publishing in top journals. For example, in the health field, data based on KN surveys, using essentially the same methodologies we use in our study, have been used in publications in JAMA,1 2 the Morbidity Mortality Weekly Report, Health Services 3 4
