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。

参与者

500 名年龄≥18 岁的参与者（N=500）的连续样本，他们接受门诊治疗（身体、职业、语言）。

干预措施

不适用。

主要观察指标

AM-PAC 医疗保险和通用认知简表和代表 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 认知项目和 11 个固定的 PROMIS 认知功能项目参数进行校准，表明项目测量的是相同的基础结构（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显示出更高的可靠性，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，并将 AM-PAC 认知原始分数映射到 PROMIS 指标上。

结论

本研究中开发的人行横道允许将分数从 AM-PAC 应用认知转换为 PROMIS 认知功能量表。
