Reliability of personal interview data

Abstract

In order to ascertain the reliability of reports of age, education, and socio-economic level as obtained under certain rather common conditions in personal interview surveys, original and repeat interviews were made about three months apart with two groups of adults, one with 888 and the other with 430 persons in the group. Product-moment correlations for the age variable were .85 and .80; for the education variable, .82 and .67; and for the socio-economic variable, .61 and .42.
