In 1999, a new self-report outcome measure, the Functional Rating Index (FRI), was developed and tested. This measure demonstrated reasonable reliability, validity and responsiveness. Since the publication of the original testing, numerous independent research teams have examined the psychometric qualities of the FRI and published their findings. The aim of this study is to review the psychometric properties of the FRI as reported by published studies. Researchers independently searched the literature for relevant studies using MEDLINE and Index to Chiropractic Literature from January 2001 to August 2009. Descriptive and outcome data was extracted using standardized forms. The psychometric properties of the FRI were analyzed with established criteria and compared head-to-head with other outcome measures. The search yielded ten studies that provided psychometric data. Reliability: Test-retest: Intraclass correlation coefficient and Cronbach's alpha were good, and FRI is equivalent to the other measures.
the FRI has good convergent validity with pain and function self-report scales and a weaker correlation with items that measure different constructs. Responsiveness: FRI was similar to the comparative measures for standardized response mean, effect size and receiver operating curve statistics. Patient acceptability: time required by the patient and staff averaged 78 seconds per administration, and there were few missing responses. The FRI demonstrates favorable measurement properties of reliability, validity and responsiveness. It provides an alternative to other self-report measures, because it is quicker for a patient to complete and can be used for patients with neck and back pain.
1999 年，一种新的自我报告结果测量工具，功能评定指数（FRI），被开发和测试。这个测量工具显示了合理的可靠性、有效性和反应度。自最初的测试发表以来，许多独立的研究小组已经检查了 FRI 的心理测量特性并发表了他们的发现。本研究旨在综述已发表研究报告的 FRI 的心理测量特性。研究人员使用 MEDLINE 和 1999 年 1 月至 2009 年 8 月的整脊文献索引，独立地搜索相关文献。使用标准化表格提取描述性和结果数据。FRI 的心理测量特性使用既定标准进行分析，并与其他结果测量方法进行了直接比较。检索结果提供了十项具有心理测量数据的研究。可靠性：重测信度：组内相关系数和 Cronbach 的 alpha 较好，FRI 与其他测量方法相当。有效性：FRI 与疼痛和功能自我报告量表具有良好的聚合有效性，与测量不同结构的项目相关性较弱。反应度：FRI 与比较测量的标准化反应均值、效应大小和接受者操作特征曲线统计数据相似。患者可接受性：患者和工作人员平均需要 78 秒的时间来完成每次评估，并且很少有缺失的反应。FRI 显示出可靠的可靠性、有效性和反应度测量特性。它提供了一种替代其他自我报告测量的方法，因为患者完成它的速度更快，并且可以用于颈部和背部疼痛的患者。
