Expanded and non-conforming answers in standardized survey interviews

Abstract

Abstract Respondents in standardized survey interviews do not always answer closed-ended questions with just a type-conforming answer, such as “yes” or “three.” Instead, they sometimes expand the type-conforming answer or provide a response that does not contain a type-conforming answer. Standardized survey methodology aims to avoid such answers because they are found to cause interviewers to deviate from their script. However, we found that many expanded and non-conforming responses do not lead to intervention by the interviewer and are treated as unproblematic. A Conversation Analytic study of survey interviews, incorporating three different surveys, with recordings available for interviews varying in number between four and 430 interviews, shows that answer attempts can be divided into five types: four turn expansions (serial extras, uncertainty markers, prefaced answers, answers followed by elaborations), and non-conforming answers. Each of these targets a specific aspect of the interview situation. A follow-up quantitative analysis of 610 Computer-Assisted Telephone Interviews (CATI) shows that expanded answers are overwhelmingly accepted by interviewers, while non-conforming answers are in most cases followed by interviewer probing.
