目的：本文的目的是讨论实际使用的理论抽样作为选择数据的方法，提供了一个更丰富和更深入的了解正在调查的现象。 设计/方法/途径：理论抽样是扎根理论研究中的一种众所周知的方法，用于根据从初始数据分析中发展出来的概念来寻找额外的数据。这种方法包括在分析过程中遵循数据导致的扩展和完善不断发展的理论。然而，缺乏详细说明进行理论抽样所需实际步骤的资料。 调查结果：作者在他们的研究中以四种方式使用了理论抽样方法：提出额外的访谈问题和/或扩大现有访谈问题的范围;招募同一组中具有额外多样性属性的参与者;以及增加一组新的参与者并扩大研究设置。 独创性/价值：理论抽样是一个有价值的和实用的方法，在定性研究中的数据处理的差距。在使用理论抽样时，必须考虑应对可能出现的挑战的潜在战略。在数据分析过程中，为实现理论整合的目的，理论抽样的使用提供了实用的建议。
Purpose: The purpose of this paper is to discuss the practical use of theoretical sampling as a method for selecting data that provide a richer and deeper understanding of the phenomenon being investigated. Design/methodology/approach: Theoretical sampling is a well-known method in grounded theory studies to seek additional data based on concepts developed from initial data analysis. This method involves following where the data have led to expand and refine the evolving theory during the analytical process. However, there is a dearth of information detailing the practical steps needed to undertake theoretical sampling. Findings: The authors used the theoretical sampling method in their study in four ways: asking additional interview questions and/or widening the scope of existing interview questions; recruiting participants with additional diversity of attributes within the same group; and adding a new group of participants and expanding research settings. Originality/value: Theoretical sampling is a valuable and practical method for the purpose of addressing gaps in the data in qualitative research. When using theoretical sampling, it is essential to consider potential strategies for countering challenges that may arise. Practical recommendations are offered on the use of theoretical sampling during data analysis, for the purpose of achieving theoretical integration.
