目的：探讨和解释信度和效度的不同概念，因为它们与社会科学和卫生保健中的测量工具有关。背景：在信度和效度这两个术语中包含不同的概念，这些概念通常解释得很差，而且它们之间经常混淆。设计：为了发展一些关于信度和效度的概念框架，基于现有的文献建立了一个概念框架。结果：信度和效度的概念框架是由信度和效度组成的，而信度和效度的概念框架是由信度和效度组成的。结论：信度包含了内部一致性、稳定性和等效性等概念。效度包括内容、表面、标准、并发、预测、结构、收敛（和发散）、因子和判别等概念。此外，对于临床实践和研究，必须确定测量工具的实用性。与临床实践的相关性。为了在临床实践中适当使用测量工具，必须确定其可靠性、有效性和可用性。
Aims.To explore and explain the different concepts of reliability and validity as they are related to measurement instruments in social science and health care.Background.There are different concepts contained in the terms reliability and validity and these are often explained poorly and there is often confusion between them.Design.To develop some clarity about reliability and validity a conceptual framework was built based on the existing literature.Results.The concepts of reliability, validity and utility are explored and explained.Conclusions.Reliability contains the concepts of internal consistency and stability and equivalence. Validity contains the concepts of content, face, criterion, concurrent, predictive, construct, convergent (and divergent), factorial and discriminant. In addition, for clinical practice and research, it is essential to establish the utility of a measurement instrument.Relevance to clinical practice.To use measurement instruments appropriately in clinical practice, the extent to which they are reliable, valid and usable must be established.
