Abstract: | In attempting to move questionnaire design from art to science,researchers use different evaluation techniques to help determinehow well questions are working. Techniques such as behaviorcoding, respondent debriefing, interviewer debriefing, cognitiveinterviewing, and nonresponse analysis all provide informationto help the questionnaire designer assess whether respondentsunderstand questions as intended and whether they are able toprovide adequate answers to them. However, these techniquesdo not actually measure question reliability. It is assumedthat questions that pass the screen of the questionnaire evaluationtechniques described above are also more likely to produce datathat are reliable and valid. In this paper, we use behaviorcoding data to predict testretest reliability. Respondentbehavior codes significantly predict such reliability whereasinterviewer codesat least in this surveydo not.We also report the results of sensitivity testing to determinewhat percentage of adequate respondent answers best predictstestretest reliability. |
