Who Can You Count On? Understanding The Determinants of Reliability.

ABSTRACT: Using reinterview data from the PATH Reliability and Validity (PATH-RV) study, we examine the characteristics of questions and respondents that predict the reliability of the answers. In the PATH-RV study, 524 respondents completed an interview twice, five to twenty-four days apart. We coded a number of question characteristics and used them to predict the gross discrepancy rates (GDRs) and kappas for each question. We also investigated respondent characteristics associated with reliability. Finally, we fitted cross-classified models that simultaneously examined a range of respondent and question characteristics. Although the different models yielded somewhat different conclusions, in general factual questions (especially demographic questions), shorter questions, questions that did not us
