Little is known about the mechanisms underlying how interviewers establish and monitor baselines of respondent behaviour. This study addresses this knowledge gap by characterising the practice of establishing baselines and measuring the accuracy of interviewer judgements based on assessments of baseline and departure behaviours. Eighteen professional interviewers viewed two videos of naturalistic interviews, reported the cues they perceived as informative for establishing and assessing a baseline, and diagnosed respondents' internal states. Participants reported multiple cue types as informative, but predominantly relied on non‐verbal cues. Overall, participants were sensitive to 27% of respondents' identified internal states but showed improvement over time. They achieved a hit rate of 20% during early interview stages and a hit rate of 33% during late stages. Although non‐verbal cues dominated reports, attending to verbal cues afforded participants greater efficiency in identifying respondent internal states. Implications and recommendations for practice are discussed.

使用基线诊断内部状态？仔细听

关于面试官如何建立和监控受访者行为基线的机制知之甚少。这项研究通过刻画建立基线的实践并根据基线和离职行为的评估来评估访调员判断的准确性，从而解决了这一知识鸿沟。18名专业面试官观看了两个自然采访的视频，报告了他们认为有助于建立和评估基准的线索，并诊断了受访者的内部状况。参与者报告多种提示类型可以提供信息，但主要依赖于非语言提示。总体而言，参与者对27％的受访者确定的内部状态敏感，但随着时间的推移表现出改善。他们在面试的早期阶段的命中率为20％，而在后期阶段的命中率为33％。尽管非语言提示在报告中占主导地位，但听从语言提示可以使参与者更有效地识别受访者的内部状态。讨论了对实践的启示和建议。
