When a large number of sampled households need to be screened for population surveys, offering an online option can save time and money. But do respondents answer the same way online that they would in person? New research on this topic appears in PLoS ONE: Comparability of in-person and web screening: Does mode affect what households report? Westat’s Jason Clark, MS, was among the coauthors, collaborating with colleagues Jessica E. Graber of the National Center for Health Statistics and Douglas Williams of the Bureau of Labor Statistics.
Households were randomly selected to complete a self-administered online survey and subsequently be screened by an interviewer during an in-person visit. The comparability of household characteristics between modes was reviewed, and the results suggested that online screening is a viable option to enumerate households.
