本文之目的在介紹茁根理論研究方法及過程，並用研究者在告灣以「茁根理論」對殘病老人家庭照護品質所作研究過程為例說明。文中介紹「茁根理論」方法如何選定研究問題、使用文獻、進行理論取樣、進行資料分析及理論評價。本文所舉例之研究，旨在探討何為家庭照護品質，研究樣本包括8個殘病老人之家庭與居家護士，共36次面對面深入訪談及參與性觀察。結果顯示，家庭照護過程之核心概念為「尋找平衡點」，「尋找平衡點」是照顧者在照顧過程中， 不斷面對許多「互相競爭的需求」時採用的過程，以維持或達成照顧上及家庭互動上的和諧及平衡。此研究結果能幫助居家護士，對「尋找平衡點」的照顧過程較為敏感且能因而採取適當的護理措施，以幫助家庭「尋找平衡點」，進而促進其家庭的照護品質。

The purpose of this article is to introduce the process of Grounded Theory methodology and illustrate with a study of "qualityof family care of frail elders in Taiwan" . Each step of Grounded Theory including the selection of research questions, the use of literature, theoretical sampling, data analysis and evaluation of theory is presented with the example study in this article. The purpose of the example study was to explore the attributes of variables related to the quality of family care of frail elders in Taiwan. A total of 8 families of frail elders and their home health care nurses were interviewed. The core category "Findinga balance point" emerged from the data."Finding a balance point" was used by caregivers to achieve or preserve interactive equilibrium in caregiving.
