The effects of using a computer assisted telephone interviewing system on response distributions, interviewer behavior, and other nonsampling errors are measured through a survey experiment which randomly assigned cases either to a paper questionnaire or a CATI version. There were few differences in response distributions obtained in the two modes, some evidence of reduced interviewer… Continue reading Computer Assisted Telephone Interviewing: Effects on Interviewers and Respondents

Estimates of interviewer effects on survey statistics are examined from nine surveys conducted over a six-year period at the Survey Research Center. Estimates of intraclass correlations associated with interviewers are found to be unstable, given the number of interviewers (30-40) used on most surveys. This finding calls into question inference from earlier studies of interviewer… Continue reading Measuring and Explaining Interviewer Effects in Centralized Telephone Surveys
