Due to demographic changes, a growing number of employees provide in-home care to an elderly family member. Previous research suggested a negative relationship between employees' eldercare demands and their work performance. However, the empirical nature of this relationship and its boundary conditions and mediating mechanisms have been neglected. The goal of this multisource study was to examine a mediated-moderation model of eldercare demands, mental health, and work performance. Drawing on the theory of conservation of resources (Hobfoll, 1989), it was expected that employees' satisfaction with eldercare tasks would buffer the negative relationship between eldercare demands and work performance, and that mental health would mediate this moderating effect. Data were collected from 165 employees providing in-home eldercare, as well as from one colleague and one family member of each employee. Results of mediated-moderation analyses supported the hypothesized model. The findings suggest that interventions that aim to increase employees' satisfaction with eldercare tasks may help protect employees from the negative effects of high eldercare demands on mental health and, subsequently, on work performance.
由于人口结构的变化，越来越多的员工为家庭中的老年成员提供家庭护理。先前的研究表明，员工的护理需求与工作绩效之间呈负相关关系。然而，这种关系的实证性质及其边界条件和中介机制一直被忽视。本多源研究的目的是检验护理需求、心理健康和工作绩效的中介调节模型。本研究以资源保存理论（Hobfoll，1989）为基础，预计员工对护理任务的满意度将缓冲护理需求与工作绩效之间的负相关关系，而心理健康将调节这种调节效应。数据来自 165 名提供家庭护理的员工，以及每位员工的一名同事和一名家庭成员。中介调节分析的结果支持了假设模型。研究结果表明，旨在提高员工对护理任务满意度的干预措施可能有助于保护员工免受高护理需求对心理健康的负面影响，进而对工作绩效产生负面影响。
