In the current climate of evidence-based practice, physiotherapy is urged to prove its worth via rigorous scientific research. However, there are concerns that limited methodologies are used to explore complex therapeutic issues, and that the profession relies too heavily on quantitative research studies to provide its evidence base. Qualitative research methods are able to explore the complexity of human behaviour and generate deeper understanding of illness behaviours and therapeutic interactions. Nevertheless, there is still a sense of distrust of qualitative research, related to the challenge of evaluating both the quality and usefulness of findings derived through qualitative methods. This discussion paper explores these issues. It examines some of the most frequently used techniques aimed at ensuring quality and value in qualitative research, such as sampling, triangulation, multiple coding, respondent validation and the use of audit trails, as well as addressing reflexivity. Because of the pluralistic and interactive nature of qualitative inquiry, the criteria used to judge quality need to be appropriate to each piece of research and should provide evidence to help readers to evaluate the calibre of the study and its relevance to their own area of work.
在当前循证实践的大环境下，物理治疗被要求通过严谨的科学研究来证明其价值。然而，有人担心用于探索复杂治疗问题的方法有限，且该专业过于依赖定量研究来提供其证据基础。定性研究方法能够探究人类行为的复杂性，并更深入地理解疾病行为和治疗互动。尽管如此，对于定性研究仍存在一种不信任感，这与评估通过定性方法得出的研究结果的质量和实用性所面临的挑战有关。本讨论文件探讨了这些问题。它审视了一些旨在确保定性研究质量和价值的最常用技术，如抽样、三角互证法、多重编码、受访者验证以及审计追踪的使用，同时也探讨了反思性。由于定性探究具有多元性和互动性，用于判断质量的标准需要适用于每项研究，并应提供证据以帮助读者评估研究的质量及其与自身工作领域的相关性。
