近年來,以「追隨者」為中心的領導風格開始流行,僕人式領導因強調關注部屬利益與服務部屬而受到矚目。組織若想要走向成功,除了關注主管的領導風格,部屬是否會受主管影響,進而展現出對組織有益的行為同等重要。本研究以自我決定理論作為主要框架,旨在探討三種不同的基本心理需求滿足是否在僕人式領導以及兩種追隨者行為─尋求回饋行為及建言行為之間存在中介效果。本研究透過問卷法來蒐集研究樣本資料,最終成功收集207對主管與部屬問卷。經過結構方程式的檢驗,本研究做出以下三個結論:(1)自主需求滿足在僕人式領導與建言行為之間具完全中介效果;(2)勝任需求滿足在僕人式領導與尋求回饋行為、建言行為之間皆具完全中介效果;(3)關係需求滿足在僕人式領導與尋求回饋行為、建言行為之間皆具完全中介效果。;In recent years, leadership styles centered on followership have become popular. Servant leadership has attracted attention due to its emphasis on serving and caring for subordinates and focusing on their interests. For an organization to succeed, it is important to consider whether subordinates are influenced by the leadership style of the supervisor and exhibit behaviors that are beneficial to the organization. The study uses self-determination theory as the main framework to explore whether the satisfaction of three different basic psychological needs would mediate the relationship between servant leadership and two follower behaviors ─ feedback-seeking behavior and voice behavior. The study collected research sample data through questionnaires and successfully collected 207 supervisor-subordinate pairs. After structural equation modeling analysis, the study reaches the following three conclusions: (1) Autonomy need satisfaction fully mediates the relationship between servant leadership and voice behavior ; (2) Competence need satisfaction fully mediates the relationship between servant leadership and both feedback-seeking behavior and voice behavior ; (3) Relatedness need satisfaction fully mediates the relationship between servant leadership and both feedback-seeking behavior and voice behavior.
