We examine relationships between interviewers’ nonverbal behaviors and adequate responding in face-to-face survey interviews. We videotaped professional interviewers administering face-to-face survey interviews and coded them for three interviewer nonverbal behaviors: smiling, nodding, and direct gaze. These nonverbal interviewer behaviors were associated with significant increases in the frequency of respondents’ adequate responses. Moreover, the nonverbal behaviors were equally likely to present in standardized and unstandardized utterances. These results suggest that interviewers’ nonverbal behaviors positively correlate with adequate responding without deviating from standardized interview protocols. We discuss implications for survey theory and interviewer training.

我们检查了面试官的非语言行为与面对面调查访谈中的充分反应之间的关系。我们录制了管理面对面调查访谈的专业采访者的视频，并将其编码为三种采访者非语言行为：微笑、点头和直接注视。这些非语言的采访者行为与受访者充分回应的频率显着增加有关。此外，非语言行为同样可能出现在标准化和非标准化的话语中。这些结果表明，采访者的非语言行为与适当的回应正相关，而不会偏离标准化的采访协议。我们讨论了对调查理论和面试官培训的影响。
