A growing body of literature points to the possibilities offered by postsurvey interviewer observations as a source of paradata to obtain insights into data quality. However, their utility in predicting actual behavior of respondents has attracted limited scholarly attention so far. Using data from Round 7 of the European Social Survey, we aim to clarify the relationship between interviewer observations and response styles (straightlining, item nonresponse, use of middle and extreme categories). We contribute to previous research by empirically verifying whether interviewer observations in face-to-face interviews can be effectively used as accurate predictors of data quality. Findings suggest that interviewers’ assessments of response behavior to some extent reflect response styles and can potentially be a valuable tool for the evaluation and improvement of survey data quality, although this seems mainly restricted to the most overt (i.e., easily observable) response styles.

面试官对受访者表现的评估是否准确反映了回应行为？

越来越多的文献指出了调查后采访者观察作为辅助数据来源获得对数据质量的洞察力所提供的可能性。然而，到目前为止，它们在预测受访者实际行为方面的效用受到的学术关注有限。使用来自欧洲社会调查第 7 轮的数据，我们旨在阐明访调员观察和回答风格（直线、项目无回答、中间和极端类别的使用）之间的关系。我们通过实证验证面试官在面对面采访中的观察是否可以有效地用作数据质量的准确预测指标，从而为之前的研究做出贡献。
