BACKGROUND Within qualitative research in-person interviews have the reputation for being the highest standard of interviewer-participant encounter. However, there are other approaches to interviewing such as telephone and e-mail, which may be appropriate for a variety of reasons such as cost, time and privacy. Although there has been much discussion of the relative values of different interview methods, little research has been conducted to assess what differentiates them using quantifiable measures. None of this research has addressed the video call, which is the interview mode most like the in-person interview. This study uses quantifiable measures generated by the interview to explore the relative value of in-person and video call interview modes. METHODS Interview data gathered by a qualitative research study exploring the views of people with IBS about hypnotherapy for their condition were used. In-person and video call interviews using the same topic guide were compared on measures of length (time and word count), proportion of time the interviewer was dominant, the number of topics generated (codes) and the number of individual statements on which those topics were based. RESULTS Both interview methods produced a similar number of words and a similar number of topics (codes) were discussed, however the number of statements upon which the variety of topics was based was notably larger for the in-person interviews. CONCLUSION These findings suggest that in in-person study interviews were marginally superior to video calls in that interviewees said more, although this was on a similar range of topics. However, the difference is sufficiently modest that time and budget constraints may justify the use of some video call interviews within a qualitative research study.

在患有肠易激综合症患者的研究中比较Skype（视频通话）和面对面的定性访谈模式-探索性比较分析。

背景技术在定性研究中，面对面访谈以面试官与参与者相遇的最高标准而著称。但是，还有其他访问方式，例如电话和电子邮件，可能由于多种原因（例如成本，时间和隐私）而适用。尽管已经对不同访谈方法的相对价值进行了很多讨论，但很少进行研究来评估使用可量化度量来区分它们的区别。这项研究都没有针对视频通话，视频通话是最类似于面对面采访的采访模式。这项研究使用访谈产生的量化指标来探讨面对面和视频通话访谈模式的相对价值。方法采用定性研究收集的访谈数据，探讨IBS患者对催眠治疗对其病情的看法。比较使用同一主题指南进行的面对面和视频电话采访，包括长度（时间和字数），访问者占主导地位的时间比例，所生成主题的数量（代码）以及针对这些主题的单个陈述的数量等量度。主题依据。结果两种访谈方法产生的单词数和主题（代码）的数量均相似，但是，面对面访谈时，基于各种主题的陈述的数量显着增加。结论这些发现表明，面对面的研究访谈在视频通话方面略胜于视频通话，因为受访者说，尽管这是在相似的主题范围内。但是，差异足够小，以至于时间和预算的限制可能证明在定性研究中使用某些视频通话采访是合理的。
