The impact of interviewer variability in an epidemiological survey
Published online by Cambridge University Press: 09 July 2009
Synopsis
One of the principal sources of error in data collected from structured interviews with respondents is the method of measurement or observation itself. In this paper the differential impact of each of a group of interviewers on the responses obtained in an epidemiological survey is examined. The effect is measured and its impact on the interpretation of individual responses, scale scores and model fitting is shown.
