本文讨论了定性研究中的抽样，描述了抽样的原理以及不同的研究人员如何描述他们的抽样技术。本文以作者参与的一个研究项目为例(1)，展示了如何将一系列定量和定性抽样技术结合起来，突出了其中的一些问题。特别是，在需要理论抽样的地方，我们发现需要一种系统的方法来识别理论上有用的抽样单位，因此我们设计了一种选择方法，我们称之为矩阵抽样，由此可以做出明智和连贯的选择。
This paper discusses sampling in qualitative research, describing the principles and how different researchers have described their sampling techniques. The example of a research project in which the authors were involved ( 1 ) is used to show how a range of quantitative and qualitative sampling techniques can be combined, highlighting some of the problems. In particular, where theoretical sampling was required, we found that a systematic way of identifying theoretically useful sampling units was needed, and so a method of selection which we have called matrix sampling was devised, whereby informed and coherent choices could be made.
