To expand an existing validated measure of basic mobility (Activity Measure for Post-Acute Care [AM-PAC]) for patients at the lowest levels of function.
Item replenishment for existing item response theory (IRT) derived measure via (1) idea generation and creation of potential new items, (2) item calibration and field testing, and (3) longitudinal pilot test.
Two tertiary acute care hospitals.
Consecutive inpatients (N=502) ≥18 years old, with an AM-PAC Inpatient Mobility Short Form (IMSF) raw score ≤15. For the longitudinal pilot test, 8 inpatients were evaluated.
Fifteen new AM-PAC items were developed, 2 of which improved mobility measurement at the lower levels of functioning. Specifically, with the 2 new items, the floor effect of the AM-PAC IMSF was reduced by 19%, statistical power and measurement breadth were greater, and there was greater measurement sensitivity in longitudinal pilot testing.
Adding 2 new items to the AM-PAC IMSF lowered the floor and increased statistical power, measurement breadth, and sensitivity.
为功能最低水平的患者扩展现有的经过验证的基本活动能力测量工具（康复护理后活动量表 [AM-PAC]）。
通过以下方式为现有项目反应理论（IRT）推导的测量工具补充项目：（1）想法生成和潜在新项目的创建，（2）项目校准和现场测试，以及（3）纵向试点测试。
两家三级急性护理医院。
连续入住的≥18 岁患者，AM-PAC 住院患者活动能力简短表（IMSF）原始分数≤15。对于纵向试点测试，评估了 8 名住院患者。
开发了 15 项新的 AM-PAC 项目，其中 2 项提高了较低功能水平的活动能力测量。具体来说，通过这 2 个新项目，AM-PAC IMSF 的下限效应降低了 19%，统计能力和测量广度增加，纵向试点测试的测量灵敏度更高。
在 AM-PAC IMSF 中添加 2 个新项目降低了下限，提高了统计能力、测量广度和灵敏度。
