Study Design Highlights

A sample of respondents from the ANES 1986 Pre-Post Study was selected for the 1987 pilot study, which was carried out, via telephone interviews, in two waves. Wave I (May 5 to May 30) encompassed 457 interviews, and Wave II (June 2 to July 2) obtained 360 reinterviews. Each wave used two questionnaires, Form A and Form B, administered to different half-samples (randomly assigned). The sample was drawn form 1986 form A respondents who had provided a telephone number for recontact. The sample was stratified on political information. The sampling fraction for the stratum was proportional to predicted response rate.
