We compared data from an Internet-based survey and a telephone-based survey during a 2009 norovirus outbreak in Oregon. Survey initiation, timeliness of response, and attack rates were comparable, but participants were less likely to complete Internet questions. Internet-based surveys permit efficient data collection but should be designed to maximize complete responses.

BACKGROUND Telephone interviews have become established as an alternative to traditional mail surveys for collecting epidemiological data in public health research. However, the use of telephone and mail surveys raises the question of to what extent the results of different data collection methods deviate from one another. We therefore set out to study possible differences in using telephone an...

BACKGROUND Pesticide use patterns are essential inputs into human pesticide exposure models. Currently, data included for modeling purposes have mostly been collected in cross-sectional surveys. However, it is questionable whether responses to one-time surveys are representative of pesticide use over longer periods, which is needed for assessment of health impact. This study was designed to eva...

This study describes strategies used to maximise recruitment to a home interview survey of mothers with young children living in areas of high deprivation. METHODS Mothers of two year old children received a letter from their GP inviting them to take ...

Telephone surveys face the challenge of assessing, and compensating for, bias from noncoverage of nontelephone households. Work by Keeter (1995) suggested that some persons and households who do not have a telephone at a particular time are actually between spells of telephone service. This basic observation, coupled with an estimation strategy proposed in a different context by Politz and Simm...
