Workplace ostracism research has examined numerous underlying mechanisms to understand the link between workplace ostracism and behavioral outcomes. Ostracism has been suggested to be an interpersonal stressor; however, research has not investigated workplace ostracism from a stress perspective. Therefore, the study investigated the mediating effect of perceived stress for the relationships between workplace ostracism and helping behavior, voicing behavior, and task performance. The study also investigated the moderating effect of psychological empowerment for the relationships between perceived stress and behavioral outcomes.
The study design was a three-wave self-reported questionnaire.
The study sampled 225 full-time employees in South Korea and regression analyses with bootstrapping were conducted to test the moderated mediation models.
The bootstrapped 95% CI around the indirect effects did not contain zero; therefore, perceived stress mediated the relationship between workplace ostracism and helping behavior (-.06), voicing behavior (-.07), and task performance (-.07). Further, the moderated mediation analyses found perceived stress mediated the relationships between workplace ostracism and behavioral outcomes only when individuals perceived low levels of psychological empowerment.
The findings suggest that workplace ostracism is a stressor and psychological empowerment can mitigate the negative effects of ostracism on behavioral outcomes.
工作场所排斥研究已经检验了许多潜在机制，以了解工作场所排斥与行为结果之间的联系。排斥被认为是一种人际应激源；然而，研究尚未从压力角度考察工作场所排斥。因此，本研究调查了感知压力在工作场所排斥与帮助行为、发声行为和任务绩效之间的关系中的中介作用。本研究还考察了心理授权对感知压力与行为结果之间关系的调节作用。
本研究采用了三波自我报告问卷的设计。
本研究在韩国抽取了 225 名全职员工，并进行了回归分析和自举检验，以检验调节中介模型。
自举 95%置信区间的间接效应不包含零；因此，感知压力在工作场所排斥与帮助行为（-.06）、发声行为（-.07）和任务绩效（-.07）之间的关系中起中介作用。此外，调节中介分析发现，只有当个体感知到低水平的心理授权时，感知压力才会在工作场所排斥与行为结果之间的关系中起中介作用。
研究结果表明，工作场所排斥是一种应激源，而心理授权可以减轻排斥对行为结果的负面影响。
