This study sought to conduct a review of content validity, which is an important phase of processes of construction and adaptation of measurement instruments. Research of comprehensive literature was conducted by means of a review of national and international databases. Initially, a description of the conceptual basis and the measurement methods used in content validity was made, with emphasis on its application in the healthcare area. It was seen that controversy exists in the literature on the terminology and concept of content validity. The recommended procedures used to check content validity during the construction and adaptation processes of instruments were described, especially the judges' assessment, which can involve qualitative and quantitative procedures. The number, selection and qualification of these judges were also described. The different methods used to quantify the level of agreement among the experts were verified, mainly the Content Validity Index (CVI). This study described aspects of the content validity process, one of the procedures to be considered by healthcare researchers and professionals who are interested in using reliable and appropriate measurements and instruments scales for given population groups.
本研究旨在对内容效度进行综述，内容效度是测量工具构建与改编过程中的一个重要阶段。通过对国内外数据库的检索进行了全面的文献研究。首先，对内容效度的概念基础和测量方法进行了描述，重点阐述了其在医疗保健领域的应用。可以看出，文献中关于内容效度的术语和概念存在争议。描述了在工具构建和改编过程中用于检验内容效度的推荐程序，特别是评委评估，这可能涉及定性和定量程序。还描述了这些评委的数量、选择和资质。核实了用于量化专家之间一致性水平的不同方法，主要是内容效度指数（CVI）。本研究描述了内容效度过程的各个方面，这是医疗保健研究人员和专业人员在希望为特定人群使用可靠且合适的测量方法和量表时应考虑的程序之一。
