ABSTRACT

Objectives

This study aimed to examine psychometric properties of the Modified Caregiver Strain Index (MCSI) in Black and White caregivers of persons living with dementia at hospital discharge.

Methods

This was a cross-sectional study using baseline data of 423 family caregivers recruited from a cluster randomized clinical control trial. Factor structure, measurement invariance, and concurrent validity of the MCSI were analyzed. The moderating role of race on the relationship between MCSI score and anxiety, depression, and burden was also examined.

Results

The two-factor model fits the data best and was invariant across race. Regarding concurrent validity, higher MCSI scores were significantly associated with higher scores on the (HADS-A; anxiety), (HADS-D; depression), and (ZBI; burden). Race moderated the relationship between MCSI score and anxiety, depression, and burden.

Conclusions

The MCSI is a valid tool to assess caregiver strain in Black and White caregivers of persons living with dementia during hospital discharge. Results suggest that the effect of MCSI score on anxiety, depression, and burden varies by race.

Clinical Implications

MCSI can be used by clinicians and service providers to help support the needs of Black and White caregivers of people living with dementia during post-hospital transition.

出院时黑人和白人痴呆症护理人员的改良护理人员应变指数

摘要

目标

本研究旨在研究出院时痴呆症患者的黑人和白人护理人员的改良护理人员应变指数 (MCSI) 的心理测量特性。

方法

这是一项横断面研究，使用了从整群随机临床对照试验中招募的 423 名家庭护理人员的基线数据。分析了 MCSI 的因素结构、测量不变性和并发有效性。种族对 MCSI 评分与焦虑、抑郁和负担之间关系的调节作用也得到了检验。

结果

双因素模型最适合数据并且在不同种族之间保持不变。关于同时有效性，较高的 MCSI 分数与较高的（HADS-A；焦虑）、（HADS-D；抑郁）和（ZBI；负担）分数显着相关。种族调节了 MCSI 评分与焦虑、抑郁和负担之间的关系。

结论

MCSI 是评估痴呆症患者出院期间黑人和白人护理人员的护理压力的有效工具。结果表明，MCSI 评分对焦虑、抑郁和负担的影响因种族而异。

临床意义

临床医生和服务提供商可以使用 MCSI 来帮助满足痴呆症患者出院后过渡期间的黑人和白人护理人员的需求。
