Special Content: The broad purposes of the data collection were to permit the NES staff and user community to assess overall differences between the two data collection techniques in sample and measurement quality, and to carry out a series of additional methodological experiments concerned with question format, computer-assisted procedures, and survey organization. Focus is on comparing data obtained by personal interview and national data probability sample with telephone computer-assisted interviews, sampling by RDD.

Design Features: Because of parallel work in the development of computer-assisted telephone interviewing at Berkeley and Michigan, the telephone sample was randomly allocated to two different interviewing sites, one operated by the University of Michigan's Survey Research Center, and one by University of California- Berkeley's Program in Computer-Assisted Survey Methods. This study took place in conjunction with the 1982 National Election Study. Telephone respondents were administered a somewhat abbreviated version of the 1982 NES in-person interview schedules, adapted for use over the telephone where appropriate, all interviewing conducted in the three months following the 1982 elections.
