Telephone survey interviewers need to be able to accurately record answers to questions. While straightforward for closed questions, this task can be complicated for open questions. We examine interviewer recording accuracy rates from a national landline random digit dial telephone survey. We find that accuracy rates are over 90% for numeric response and interviewer-code, single-response items but are astonishingly low (49%) for a multiple-answer, nominal, interviewer-code item. Accuracy rates for narrative open questions were around 90% for themes but only about 70% for themes and elaborations. Interviewer behaviors (e.g., probing, feedback) are generally associated with lower accuracy rates. Implications for questionnaire design, interviewer training, and coding procedures are discussed.

采访者在电话调查中记录对数字、采访者现场代码和开放式叙述性问题的回答的效果如何？

电话调查访问员需要能够准确记录问题的答案。虽然对于封闭式问题很简单，但对于开放式问题，这项任务可能很复杂。我们从全国固定电话随机数字拨号电话调查中检查访调员记录准确率。我们发现，数字回答和面试官代码、单一回答项目的准确率超过 90%，但对于多项回答、名义、面试官代码项目，准确率低得惊人 (49%)。主题的叙述性开放式问题的准确率约为 90%，但主题和阐述的准确率仅为 70%。采访者的行为（例如探询、反馈）通常与较低的准确率相关。讨论了问卷设计、访问员培训和编码程序的影响。
