Reliability and validity are among the most important and fundamental domains in the assessment of any measuring methodology for data-collection in a good research. Validity is about what an instrument measures and how well it does so, whereas reliability concerns the truthfulness in the data obtained and the degree to which any measuring tool controls random error. The current narrative review was planned to discuss the importance of reliability and validity of data-collection or measurement techniques used in research. It describes and explores comprehensively the reliability and validity of research instruments and also discusses different forms of reliability and validity with concise examples. An attempt has been taken to give a brief literature review regarding the significance of reliability and validity in medical sciences.
信度和效度是评估任何数据收集测量方法的重要且基本的领域之一，这对于良好的研究至关重要。效度是指工具测量的内容以及它的测量效果如何，而信度则涉及到所获得数据的真实性以及任何测量工具控制随机误差的程度。本次叙述性综述旨在讨论数据收集或测量技术在研究中的可靠性和有效性的重要性。它全面描述和探讨了研究工具的可靠性和有效性，并用简明的例子探讨了不同形式的可靠性和有效性。本文还尝试简要综述了医学科学中可靠性和有效性的重要性。
