摘要

仪器的有效性是临床医生在选择用于数据收集的工具时要考虑的另一个重要问题。广义地说，有效性指的是一个工具测量它应该测量的东西的程度。虽然效度是一个统一的概念，但本文探讨了三种常见的效度类别:内容效度、标准效度和构念效度。

Exploring the validity of data-gathering instruments.

The validity of an instrument is another important issue for the clinician to consider when selecting a tool for use in data collection. Broadly defined, validity refers to the extent to which an instrument measures what it is supposed to be measuring. Although validity is a unitary concept, this article explores three common categories of validity: content, criterion-related, and construct validity.
