Scripted consultations provide the opportunity to vary and study the effect of specific elements of medical communication. These scripted consultations are role-played, videotaped and then judged by analogue patients. Most studies applying this methodology have provided little insight into how they created internally and externally valid written and role-played scripts. In this paper we aim to address this gap by providing a detailed description of a scripted video-vignette study's methodology.
Following the five phases of creating and implementing scripted video-vignettes the current study's methodology is described: (1) deciding if video-vignettes are appropriate, (2) developing a valid script, (3) designing valid manipulations, (4) converting the scripted consultations to video, (5) administering the videos in an experiment.
Following these phases and four validation steps internally and externally valid vignettes were developed.
The detailed description of the current study's methodology produced general recommendations for scripted video-vignette studies, such as the importance of validating both the written as well as the role-played scripts and involving both experts and lay people in validating the scripts. For other choices no golden standard exists.
The presented methodology and recommendations may serve as a source of inspiration for future scripted video-vignette studies.
脚本咨询提供了改变和研究医学沟通特定要素效果的机会。这些脚本咨询是角色扮演的，被录像，然后由模拟患者进行判断。大多数应用这种方法的研究几乎没有深入了解他们如何创建内部和外部有效的书面和角色扮演脚本。本文旨在通过详细描述脚本视频短片研究的方法学来解决这一差距。
在创建和实施脚本视频短片的五个阶段之后，描述了当前研究的方法学：（1）决定视频短片是否合适，（2）开发有效的脚本，（3）设计有效的操作，（4）将脚本咨询转换为视频，（5）在实验中播放视频。
通过这些阶段和四个验证步骤，开发了内部和外部有效的视频短片。
当前研究方法学的详细描述为脚本视频短片研究提供了一般性建议，例如验证书面和角色扮演脚本的有效性以及让专家和非专业人员参与脚本验证的重要性。对于其他选择，不存在黄金标准。
所提出的方法学和建议可以为未来的脚本视频短片研究提供灵感。
