This study concerns the development of a short version of a well-known and much used clinimetric instrument called the Sickness Impact Profile (SIP). The SIP is a generic measure of functional status. Based on findings of a principal components analysis of over 800 SIPs from a multi-diagnostic population, a selection of 68 items divided over 6 dimensions was made and initially tested. As no support was found for the statistical validity of the categorical structure of the original SIP, a new structure, discovered through principal components analysis, was used as the basis for selecting items. Comparison of the scores on the selection with information provided by the original SIP showed very promising results: the 68 item selection may serve as a valid short SIP-version.
本研究涉及一种著名且广泛使用的临床测量工具——疾病影响量表（SIP）的简短版本的开发。SIP是一种功能状态的通用测量方法。基于对来自多诊断人群的800多个SIP进行主成分分析的结果，选取了68个项目，分为6个维度，并进行了初步测试。由于未发现原始SIP分类结构的统计有效性的支持，通过主成分分析发现的新结构被用作选择项目的基础。将所选项目的得分与原始SIP提供的信息进行比较，结果非常有前景：这68个项目的选择可以作为一个有效的SIP简短版本。
