工作要求-資源模型是了解員工在職場之幸福感的重要理論依據。以此模型為基礎，本研究提出以個人觀點出發，加入工作狂傾向與心理抽離等變項，以了解工作要求如何對員工的幸福感產生影響。具體來說，本研究探究個人要求（工作狂傾向）與個人資源（心理抽離）在此模型中（於健康折損路徑與動機路徑）的中介角色，以及工作與個人的資源對該模型中健康折損路徑之調節作用。簡言之，本研究關注如何降低高度工作要求導致的不良影響與並提升對員工的正面影響。

本研究對台灣職場中不同產業的341位現職員工進行問卷調查。研究結果發現，工作狂傾向中介認知要求與耗竭之正向關係，而心理抽離並未於動機路徑中產生中介效果。社會支持並未調節認知要求與工作狂傾向之正向關係，然與預期相反的，社會支持正向調節工作狂傾向與耗竭之正向關係。進一步分析顯示，該調節效果源自社會支持中的同事支持構面。心理抽離的調節角色則未受到驗證。

The Job Demands-Resources (JD-R) model has been a well-established and overarching model for understanding occupational wellbeing across various contexts. Based on the JD-R model, this study puts forth insights into microscopic mechanisms under which work demands translate into wellbeing outcomes, extending it by incorporating workaholism and psychological detachment. Specifically, the present study addresses two main concerns in work settings, how to decrease the adverse effects of high job demands and boost employees’ work engagement, by testifying: (1) the mediating role of one personal demand, workaholism, and one personal resource, psychological detachment, respectively in the dual paths of the JD-R model, and (2) whether the adverse influence of high-level work demands and the tendency to work excessively can be alleviated by job and personal resources.

This study applied online questionnaires and collected data from 341 incumbent Taiwanese employees from varying industries. The results confirmed that workaholism mediated the positive correlation between exhaustion and cognitive demands, while psychological detachment did not hold as one mediator in the motivational path. Besides, social support did not buffer the correlation between cognitive demands and workaholism, while in shark contrast to expected, it was found to positively moderate the positive correlation between workaholism and exhaustion. Additional analysis showed that this theoretically contradictory finding derived from coworker support. However, psychological detachment was not identified as a moderator.
