Objective
To link the Activity Measure for Post-Acute Care (AM-PAC) Applied Cognition to the Patient-Reported Outcomes Measurement Information System (PROMIS) Cognitive Function, allowing for a common metric across scales.
Design
Cross-sectional survey study.
Setting
Outpatient rehabilitation clinics.
Participants
Consecutive sample of 500 participants (N=500) aged ≥18 years presenting for outpatient therapy (physical, occupation, speech).
Interventions
Not applicable.
Main Outcome Measures
AM-PAC Medicare and Generic Cognition short forms and PROMIS Cognitive Function items representing the PROMIS Cognitive Function item bank.
Results
The calibration of 25 AM-PAC cognition items with 11 fixed PROMIS cognitive function item parameters using item-response theory indicated that items were measuring the same underlying construct (cognition). Both scales measured a wide range of functioning. The AM-PAC Generic Cognitive assessment showed more reliability with lower levels of cognition, whereas the PROMIS Cognitive Function full-item bank was more reliable across a larger distribution of scores. Data were appropriate for a fixed-anchor item response theory–based crosswalk and AM-PAC Cognition raw scores were mapped onto the PROMIS metric.
Conclusions
The crosswalk developed in this study allows for converting scores from the AM-PAC Applied Cognition to the PROMIS Cognitive Function scale.

将 AM-PAC 认知与 PROMIS 认知功能联系起来
客观的
将急性后护理活动测量 (AM-PAC) 应用认知与患者报告结果测量信息系统 (PROMIS) 认知功能联系起来,从而实现跨尺度的通用指标。
设计
横断面调查研究。
环境
门诊康复诊所。
参加者
连续抽样 500 名年龄≥18 岁的参与者 (N=500),接受门诊治疗(身体、职业、言语)。
干预措施
不适用。
主要成果指标
AM-PAC 医疗保险和通用认知简表以及代表 PROMIS 认知功能项目库的 PROMIS 认知功能项目。
结果
使用项目反应理论对 25 个AM -PAC 认知项目与 11 个固定的 PROMIS 认知功能项目参数进行校准表明,这些项目正在测量相同的基础结构(认知)。两种量表都测量了广泛的功能。 AM-PAC 通用认知评估在认知水平较低的情况下表现出更高的可靠性,而 PROMIS 认知功能全项目库在更大的分数分布中更可靠。数据适用于基于固定锚项目响应理论的人行横道,AM-PAC 认知原始分数被映射到 PROMIS 指标上。
结论
本研究中开发的人行横道可以将 AM-PAC 应用认知的分数转换为 PROMIS 认知功能量表。
