Can Conversational Interviewing Improve Survey Response Quality Without Increasing Interviewer Effects?
实验研究发现，对话式访谈能减少复杂调查问题的回答偏差，且不会显著增加访员内部相关性，从而提升调查估计质量。
Summary Several studies have shown that conversational interviewing (CI) reduces response bias for complex survey questions relative to standardized interviewing. However, no studies have addressed concerns about whether CI increases intra-interviewer correlations (IICs) in the responses collected, which could negatively impact the overall quality of survey estimates. The paper reports the results of an experimental investigation addressing this question in a national face-to-face survey. We find that CI improves response quality, as in previous studies, without substantially or frequently increasing IICs. Furthermore, any slight increases in the IICs do not offset the reduced bias in survey estimates engendered by CI.
