目標：本研究目的旨在探討大臺北地區區域級以上教學醫院品管圈領導型態與團體效能的相關性。方法：本研究採用預測相關性之研究設計，以Stogdill的領導型態LBDQ-II及黃敏萍的團體效能，針對大臺北地區醫院品管圈目標成員於2002年5月至6月間以結構式問卷進行資料蒐集。16家醫院品管圈問卷共回收263圈（86.8%），成員共1994人。以團體成員為研究對象。結果：本研究結果，自邏輯斯迴歸分析中獲得工作-體恤導向並重領導型態與團體效能間最具有統計上的顯著正相關性（OR＝1.47，p＜.001），而多變量迴歸分析中亦顯示工作-體恤導向並重領導型態與團體效能間最具有統計上的顯著正相關性（β＝.052，p＜.001）。本研究結果與O'Donnell和O'Donnell提出最能支持品管圈團體效能之領導型態是關心生產及關心員工並重的領導型態相吻合，亦具有Blake和Mouton管理方格理論之民主型領導型態特徵。結論：本研究結果發現工作—體恤導向並重領導型態可提供醫院推行品管圈基礎訓練課程，增進人群關係與團體互動，創造持續性高團體效能之參考。

　　　　　Objectives: The aim of the study was to examine the association between the leadership styles and group effectiveness of quality control circles (QCCs) of hospitals accredited at the level beyond regional teaching in the Taipei area.Methods: Based on the predictive corelational design, data were collected from target members of QCCs by using structured questionnaires modified from Stogdill's LBDQ-II and Hwang's group effectiveness questionnaires from May 2002 to June 2002. At a group response rate of 86.8%, 263 QCC groups including 1994 cases from 16 hospitals in the Taipei area were enrolled for analysis using individual circle members as the study targets.Results: The result of logistic regression analysis revealed significantly positive association between combined task and consideration-oriented leadership and group effectiveness (OR=1.47, p＜ .001). Multiple regression analysis also showed considerably positive association between combined task and consideration-oriented leadership and group effectiveness (β=.052, p＜.001). The results were consistent with the leadership of combined product center and people center as the best one to promote the group effectiveness reported by O'Donnell ＆ O'Donnell and the characteristics of democratic leadership style in the managing grid theory proposed by Blake and Mouton.Conclusions: This study discovers the leadership style of combined task and consideration-orientation is a basic aspect in the training course of enhancing hospital QCC effectiveness, can promote human relations and group interactions, and, moreover, achieves persistently high group effectiveness.
