多段因子小图设计（MSFV）结合了实验设计和概率抽样的元素，以及定性研究的归纳、探索方法。msfv允许研究人员调查由于伦理或后勤方面的考虑而难以研究的课题。研究人员向参与者展示了关于假想人物的短篇故事。这些故事包括2 - 5个部分，其中随机分配的维度依次介绍。研究人员控制维度呈现的发生和时间。受访者在每个环节结束后都会被问及问题。msfv可能包括书面、口头和视觉刺激。这些有效的设计在复杂的、多维的环境中引出关于因果关系的定量数据和定性数据。我们讨论了如何发展MSFV，并提出了避免问题的方法。
The multiple segment factorial vignette design (MSFV) combines elements of experimental designs and probability sampling with the inductive, exploratory approach of qualitative research. MSFVs allow researchers to investigate topics that may be hard to study because of ethical or logistical concerns. Participants are presented with short stories about hypothetical characters. These stories comprise 2 - 5 segments in which randomly assigned dimensions are introduced sequentially. Researchers control the occurrence and timing of when dimensions are presented. Respondents are asked questions after each segment. MSFVs may include written, oral, and visual stimuli. These efficient designs elicit quantitative data about causal relations and qualitative data within complex, multidimensional contexts. We discuss how to develop MSFV and suggest ways to avoid problems.
