STUDY DESIGN HIGHLIGHTS:
Each study employed a different algorithm for selecting household telephone numbers. The 1988 Senate study utilized a Waksberg-Mitofsky design, in the first stage of which working blocks of household numbers (hundred-number blocks) were sampled with probability proportional to size (PPS). Among these primary sampling units, 25 were chosen for each state, and then a selection of telephone numbers from each HNB was chosen by a restricted simple random sampling procedure. The 1990 Senate Election Study used, within states, a "PPS-to-listed counts" two-stage design, by which approximately half of the sample was selected from a frame of listed numbers and half was generated using an RDD procedure from the set of hundred series in the list sample. In the 1992 Senate Election Study, a "list assisted" or "listed hundred series" RDD sample design was employed for one-stage selection of telephone numbers without clustering, selecting telephone numbers using the GENESYS RDD sampling system through Marketing Systems Group. 1992 samples of telephone numbers were selected from a frame consisting of all the possible numbers that could be generated from hundred series that had at least two listed household phone numbers.
The nine questionnaire versions used in 1988 and 1990 corresponded to different combinations for types of Senate and House races. In 1992, with reduced House-level question content in comparison to the 1988 and 1990 Senate studies, only 2 questionnaires were necessary: one for California, which had two Senate races, and one for all other states. Interviews were conducted November 14-December 20, 1988 for the 1988 Senate study; for the 1990 and 1992 Senate studies, interviewing was conducted during the time periods of November 7-December 22, 1990 and November 4-December 8, 1992, respectively. There were 3,145 completed interviews in the 1988 Senate study, 3,349 in the 1990 Senate study, and 2,759 in the 1992 Senate Study.
