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.

摘要

本研究旨在通过 Rasch 分析和假设检验来测试痴呆症老年人使用的 UMOVE 移动屏幕的可靠性和有效性。UMOVE 移动屏幕（UMOVE）侧重于九项活动：听从指令、肌肉力量和基本功能性移动任务。经过培训的评估员对 244 名患者进行了评估，其中大多数是女性（62%），白人（71%）。基于 Rasch 分析，有证据表明项目和人员可靠性良好（指数>0.80），INFIT 统计数据良好，根据 OUTPUT 统计数据，只有一个项目符合模型。基于假设检验，有效性得到了支持。没有证据表明种族和性别之间存在差异项目功能。项目映射引起了对 UMOVE 移动屏幕评估的整个移动范围的项目分布的关注。未来的测试应考虑添加一些更简单和更困难的项目。
