基本原理、目的和目标 缺乏使用具有良好心理测量特性的客观临床工具的医疗保健从业者。研究人员还需要改进对这些临床工具的有效性和可靠性结果的报告。因此，为了促进使用有效和可靠的工具或测试进行临床评估，本文报告了开发一种批判性评估工具来评估客观临床工具的心理测量特性。方法开发新的批判性评估工具遵循五个步骤：（1）初步概念决策； (2) 定义关键概念； (3)物品生成； (4) 表面效度评估； (5)最终工具的制定。结果新的批判性评价工具由13个项目组成，其中5个项目涉及效度和信度研究，4个项目仅涉及效度研究，4个项目涉及信度研究。这13个项目可以分为是、否或不适用。结论这一批判性评估工具将帮助医疗保健从业者批判性地评估相关文献，并帮助研究人员提高客观临床工具的有效性和可靠性的报告质量。
Rationale, aim and objectives There is a lack of health care practitioners using objective clinical tools with sound psychometric properties. There is also a need for researchers to improve their reporting of the validity and reliability results of these clinical tools. Therefore, to promote the use of valid and reliable tools or tests for clinical evaluation, this paper reports on the development of a critical appraisal tool to assess the psychometric properties of objective clinical tools.Method A five-step process was followed to develop the new critical appraisal tool: (1) preliminary conceptual decisions; (2) defining key concepts; (3) item generation; (4) assessment of face validity; and (5) formulation of the final tool.Results The new critical appraisal tool consists of 13 items, of which five items relate to both validity and reliability studies, four items to validity studies only and four items to reliability studies. The 13 items could be scored as yes, no or not applicable.Conclusion This critical appraisal tool will aid both the health care practitioner to critically appraise the relevant literature and researchers to improve the quality of reporting of the validity and reliability of objective clinical tools.
