基于文献证据检索的循证研究效度检验机理探析

Exploring the Validity Testing Mechanism of Literature Evidence Retrieval Basis of Evidence-Based Research

通过对原始研究证据加以整合以获得更高层次证据是循证研究的基本目标,而文献证据检索则是循证研究提高效度的基本保障。在对研究效度和测量效度这两类主要效度指标与循证研究的关系加以解析的基础上,对照了自然科学与社会科学领域的获取研究证据的范式,并提出了“循证研究的本质是提高证据整合的效度”的理论观点。进而,通过系统性文献调查,总结了影响循证研究效度的七种因素,并在对循证研究领域证据整合历史发展进程加以梳理的基础上提出,元分析(Meta-analysis)是提高证据整合效度的主要工具。最后,本文从文献证据检索之于循证研究质量的可能影响及科学性评估指标等方面入手,对循证研究效度检验机制的建立展开了前瞻性瞭望。

Integrating the original research evidence to obtain higher-level evidence is the basic goal of evidence-based research,and yet document evidence retrieval is the basic guarantee to improve the validity of evidence-based research.Based on the analysis of the relationship between research validity and measurement validity and evidence-based research,this paper contrasts the paradigms of obtaining research evidence in the fields of natural science and social science,and puts forward the theoretical view that"the essence of evidence-based research is to improve the validity of evidence integration".Furthermore,through systematic literature survey,seven factors influencing the validity of evidence-based research were summarized,and on the basis of combing the historical development process of evidence integration in the field of evidence based research,meta analysis was proposed as the main tool to improve the validity of evidence integration.Finally,this paper starts with the possible impact of literature evidence retrieval on the quality of evidence-based research and scientific evaluation indicators,and looks forward to the establishment of the validity testing mechanism of evidence-based research.
