The researchers' assumptions invariably influence research outcomes. This is true for both qualitative and quantitative studies. Assumptions or choices regarding underlying theories, causal relations, study setting and population, sampling strategies, participant non-response, data collection, data analysis, and researchers' perceptions and interpretations of results are among factors that can induce uncertainty in research findings. Researchers tend to treat these factors as potential study limitations, but how they may impact research findings is rarely explicated and, therefore, mostly unknown. In this article, we approach uncertainty as unavoidable in research and argue that communicating about uncertainty can inform researchers, policy makers and practitioners about the validity and applicability of the study findings for their interests and contexts. We illustrate approaches to address, interpret, and explicate uncertainty in medical education research in both qualitative and quantitative paradigms. Across research paradigms, we call on researchers to consider the uncertainty in their research findings, employ appropriate methods to explore its extent and effects in their work, and communicate it explicitly in their research papers. This will help to advance our understanding of the nature and implications of the emerging knowledge in our field.
研究人员的假设总是会影响研究结果。定性研究和定量研究都是如此。关于基础理论、因果关系、研究背景和人群、抽样策略、参与者无应答、数据收集、数据分析以及研究人员对结果的认知和解释等方面的假设或选择,都是可能导致研究结果存在不确定性的因素。研究人员往往将这些因素视为潜在的研究局限,但它们如何影响研究结果却很少得到阐释,因此大多不为人知。在本文中,我们认为研究中的不确定性是不可避免的,并主张就不确定性进行沟通能够让研究人员、政策制定者和从业者了解研究结果对于他们的利益和背景而言的有效性和适用性。我们阐述了在定性和定量范式下处理、解释和阐明医学教育研究中不确定性的方法。在所有研究范式中,我们呼吁研究人员考虑其研究结果中的不确定性,采用适当方法在其工作中探究其程度和影响,并在研究论文中明确传达。这将有助于增进我们对本领域新兴知识的性质和影响的理解。
