Abstract
The use of the p-value in quantitative research, particularly its threshold of "P < 0.05" for determining "statistical significance," has long been a cornerstone of statistical analysis in research. However, this standard has been increasingly scrutinized for its potential to mislead findings, especially when the practical significance, the number of comparisons, or the suitability of statistical tests are not properly considered. In response to controversy around use of p-values, the American Statistical Association published a statement in 2016 that challenged the research community to abandon the term "statistically significant". This stance has been echoed by leading scientific journals to urge a significant reduction or complete elimination in the reliance on p-values when reporting results. To provide guidance to researchers in health professions education, this paper provides a succinct overview of the ongoing debate regarding the use of p-values and the definition of p-values. It reflects on the controversy by highlighting the common pitfalls associated with p-value interpretation and usage, such as misinterpretation, overemphasis, and false dichotomization between "significant" and "non-significant" results. This paper also outlines specific recommendations for the effective use of p-values in statistical reporting including the importance of reporting effect sizes, confidence intervals, the null hypothesis, and conducting sensitivity analyses for appropriate interpretation. These considerations aim to guide researchers toward a more nuanced and informative use of p-values.
在定量研究中使用 p 值，特别是其用于确定 "统计显著性 "的临界值 "P < 0.05"，长期以来一直是研究中统计分析的基石。然而，这一标准因其可能误导研究结果而受到越来越多的审查，尤其是在没有适当考虑实际意义、比较次数或统计检验的适宜性时。为了回应围绕使用 p 值的争议，美国统计协会于 2016 年发表声明，要求研究界放弃 "统计学意义 "一词。这一立场得到了主要科学期刊的响应，敦促在报告结果时大幅减少或完全取消对 p 值的依赖。为了给卫生专业教育研究人员提供指导，本文简明扼要地概述了目前关于 p 值的使用和定义的争论。本文通过强调与 p 值解释和使用相关的常见误区（如误读、过分强调以及错误地将结果分为 "显著 "和 "不显著"）来反映这一争论。本文还概述了在统计报告中有效使用 p 值的具体建议，包括报告效应大小、置信区间、零假设以及进行敏感性分析以进行适当解释的重要性。这些考虑因素旨在指导研究人员更细致、更翔实地使用 p 值。
期刊介绍：
Perspectives on Medical Education mission is support and enrich collaborative scholarship between education researchers and clinical educators, and to advance new knowledge regarding clinical education practices.
Official journal of the The Netherlands Association of Medical Education (NVMO).
Perspectives on Medical Education is a non-profit Open Access journal with no charges for authors to submit or publish an article, and the full text of all articles is freely available immediately upon publication, thanks to the sponsorship of The Netherlands Association for Medical Education.
Perspectives on Medical Education is highly visible thanks to its unrestricted online access policy.
Perspectives on Medical Education positions itself at the dynamic intersection of educational research and clinical education. While other journals in the health professional education domain orient predominantly to education researchers or to clinical educators, Perspectives positions itself at the collaborative interface between these perspectives. This unique positioning reflects the journal’s mission to support and enrich collaborative scholarship between education researchers and clinical educators, and to advance new knowledge regarding clinical education practices. Reflecting this mission, the journal both welcomes original research papers arising from scholarly collaborations among clinicians, teachers and researchers and papers providing resources to develop the community’s ability to conduct such collaborative research. The journal’s audience includes researchers and practitioners: researchers who wish to explore challenging questions of health professions education and clinical teachers who wish to both advance their practice and envision for themselves a collaborative role in scholarly educational innovation. This audience of researchers, clinicians and educators is both international and interdisciplinary.
The journal has a long history. In 1982, the journal was founded by the Dutch Association for Medical Education, as a Dutch language journal (Netherlands Journal of Medical Education). As a Dutch journal it fuelled educational research and innovation in the Netherlands. It is one of the factors for the Dutch success in medical education. In 2012, it widened its scope, transforming into an international English language journal. The journal swiftly became international in all aspects: the readers, authors, reviewers and editorial board members.
The editorial board members represent the different parental disciplines in the field of medical education, e.g. clinicians, social scientists, biomedical scientists, statisticians and linguists. Several of them are leading scholars. Three of the editors are in the top ten of most cited authors in the medical education field. Two editors were awarded the Karolinska Institute Prize for Research. Presently, Erik Driessen leads the journal as Editor in Chief.
Perspectives on Medical Education is highly visible thanks to its unrestricted online access policy. It is sponsored by theThe Netherlands Association of Medical Education and offers free manuscript submission.
