Abstract

The purpose of this study was to test the reliability and validity of the UMOVE Mobility Screen in older adults living with dementia using a Rasch analysis and hypothesis testing. The UMOVE Mobility Screen (UMOVE) focuses on nine activities: following commands, muscle strength, and basic functional mobility tasks. Trained evaluators completed assessments on 244 patients, the majority of whom were female (62%), and White (71%). Based on Rasch Analysis, there was evidence of good item and person reliability (indexes > 0.80), good INFIT statistics, and only one item fitting the model based on OUTFIT statistics. Validity was supported based on hypothesis testing. There was no evidence of Differential Item Functioning between races and genders. Item mapping raised concerns about the spread of the items across the full spectrum of mobility assessed in the UMOVE Mobility Screen. Future testing should consider adding some easier and some more difficult items.

一项使用Rasch分析和假设检验来评估住院老年人UMOVE移动筛查的心理测量特性的描述性研究。

本研究的目的是使用Rasch分析和假设检验来检验UMOVE移动筛查在老年痴呆患者中的可靠性和有效性。UMOVE移动屏幕（UMOVE）专注于九项活动：以下命令、肌肉力量和基本功能性移动任务。经过培训的评估人员完成了244名患者的评估，其中大多数是女性（62%）和白人（71%）。基于Rasch分析，有证据表明项目和人员的可靠性良好（指数>0.80），INFIT统计数据良好，并且只有一个项目符合基于OUTFIT统计的模型。有效性基于假设检验。没有证据表明种族和性别之间存在差异项目功能。项目映射引起了人们对UMOVE移动屏幕中评估的项目在全方位移动中的分布的担忧。未来的测试应该考虑添加一些更容易和更难的项目。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
