過去研究知覺組織支持和組織公民行為之間的關係,主要的角度是從社會交換論來探討,本研究除了社會交換理論外,整合了角色理論這樣的概念,將角色定義幅度作為組織公民行為與知覺組織支持的中介變項。本研究主要的目的在於探討,員工的角色定義幅度是否為知覺組織支持(知覺組織支持和知覺主管支持)與組織公民行為的中介變項,並且針對三個變項之間彼此不同的層次關係作一個完整的研究。亦即,知覺主管支持和知覺組織支持會透過個人層級或是組織層級的角色定義對不同層級的組織公民行為產生不同的影響效果。本研究採用問卷法,受試者是公私立的營利單位員工,與該員工的直屬主管,樣本採對偶方式收集。本研究採取便利性抽樣,總共回收了305筆配對資料。本研究的結果顯示:(1)員工知覺組織支持或知覺主管支持越高時,所表現出不同層級(組織層級和個人層級)的組織公民行為越多(2)當員工擴大不同層級(組織層級和個人層級)的角色定義幅度時,員工會分別表現出更多不同層級的組織公民行為(3)角色定義幅度為組織公民行為與知覺組織支持的中介變項。最後本研究將根據研究結果,進一步說明未來研究方向以及管理上的實務意涵。
Previous researches about the relationship between perceived organizational support and organizational citizenship behavior were mainly based on the point of view of social exchange theory. This research, not only includes social exchange theory but also integrates the concept of role theory, which defines role definition breadth as mediating effect of organizational citizenship behavior and perceived organizational support. The main purpose of this research is to discuss if employee’s role definition breadth is mediating effect of perceived organizational support and organizational citizenship behavior. There are 305 questionnaires surveyed by employees and their supervisor. The result indicate that: First, employee with high perceived supervisor support or perceived organizational support, have more organizational citizenship behavior; second, when employees enlarge their role definition breadth , they will show more organizational citizenship behavior; third, role definition breadth have significant mediating effect between organizational citizenship behavior and perceived organizational support. The outcome of this research further represents the direction of future research and practical meaning of management.
