近期管理學界對於冒牌者症候群的研究日益增加，然而卻較少有研究同時檢視冒牌者症候群如何影響員工在職場上的績效表現與職涯結果。本研究以冒牌者症候群所引發的害怕成功、害怕失敗做為心理機制，檢視其對任務績效及階層停滯的影響，並納入知覺組織圈內人地位做為干擾變數，探討圈內人地位越高是否會讓冒牌者感到更害怕成功、失敗，進而更影響後續任務與職涯後果。
本研究採問卷調查法，以兩個時間點、主管及員工兩個來源收集資料，共收集261份主管與員工配對資料，本研究使用多層次路徑分析進行假設檢定，研究結果顯示：(1) 冒牌者症候群會透過提升害怕成功，進而增加主管評估之任務績效；(2) 冒牌者症候群會透過提升害怕失敗，進而增加階層停滯的程度；(3) 當員工知覺組織圈內人地位程度高時，會增強冒牌者症候群與害怕成功間的正向關係，同時亦會增強冒牌者症候群透過害怕成功影響主管評估任務績效的正向間接效果；(4) 知覺組織圈內人地位程度高時，亦會增強冒牌者症候群與害怕失敗間的正向關係，進而增強冒牌者症候群透過害怕失敗影響階層停滯的正向間接效果。最後，本研究提供冒牌者症候群員工的相關的管理意涵供企業界參考，並對冒牌者症候群與任務績效及階層停滯的相關文獻做出貢獻。

Recent management research has increasingly focused on imposter syndrome, yet few studies examine its impact on employees' job performance and career outcomes. This study explores how fear of success and fear of failure, induced by imposter syndrome, affect task performance and hierarchical plateau, considering perceived insider status as a moderating variable.
Using a questionnaire survey method, data were collected from supervisors and employees at two time points, totaling 261 matched pairs. Multilevel path analysis revealed that: (1) imposter syndrome increases supervisors' task performance assessments by elevating fear of success; (2) imposter syndrome heightens hierarchical plateau by increasing fear of failure; (3) higher perceived insider status strengthens the relationship between imposter syndrome and fear of success, enhancing its positive effect on task performance assessments; (4) higher perceived insider status also intensifies the link between imposter syndrome and fear of failure, amplifying its impact on hierarchical plateau. Finally, this study offers management insights for dealing with employees experiencing imposter syndrome and adds to the literature on imposter syndrome, task performance, and hierarchical plateau.
