Abstract

Evidence-based dermatology has necessitated the development of rating scales that measure multidimensional and abstract constructs, such as quality of life. This article discusses some basic psychometric concepts, such as reliability, validity, standardization, and measurement precision, which need to be considered when choosing a clinical rating instrument. Also discussed is the impact of these parameters on increasing the statistical power of a clinical trial.

摘要

循证皮肤病学要求开发能够测量多维抽象概念（如生活质量）的评定量表。本文讨论了一些基本的心理测量学概念，如信度、效度、标准化和测量精度，在选择临床评定工具时需要考虑这些因素。还讨论了这些参数对提高临床试验统计效能的影响。
