文化能力是社會工作重要的實踐，會影響服務品質和社會正義的實現。目前，臺灣關於原住民社會工作文化能力之研究十分匱乏，極需要建基於實證基礎的研究豐富其內涵。本研究透過與2位學者、19位在花蓮縣原住民部落提供服務的社會工作者和8位原住民服務使用者的深度訪談，了解在部落中，社會工作文化能力的內涵。研究發且也部落社會工作文化能力要從六大面向進行思考，包括具有文化認同與文化排除機制的語言；以歷史情感脈絡及部落整體為考量的關係；以人本和文化尊重為基礎的態度價值；重視專業、文化知識和知識整合；強調專業與文化反應的技術策略；以原住民族權利、生存發展為考量的文化安全。這些面向強調在助人的過程中，要同時注重個體及群體維度。文化能力不應只是一個強調有效服務的過程，更是一個在政策、專業和實務各個層面上反映原住民族主體性，以民族、部落長遠發展、生存權利及文化安全為考量的一個過程。本文最後針對原住民社會工作教育與訓練、原住民族政策及原住民社會工作文化能力研究提出建議。

Cultural competence is vital to effective Indigenous social work practice, affecting service quality and the realization of social justice. A review of literature suggested that there is little knowledge of cultural competence in Indigenous social work in Taiwan, and there is a lack of consistent view on its definition and intellectual construct. By using a qualitative research method, 21 service providers and 8 Indigenous service users were interviewed in Hualien county to explore their understanding of cultural competence in Indigenous social work . The research reveals that six interrelated dimensions, including language, relationship, attitudes and values, knowledge, s kills and cultural safety are important components of the framework. The further analysis suggests that cultural competence is not only a process of achieving effective practice, but also a process of recognising Indigenous people's subjectivity, promoting Indigenous development and ensuring their rights and cultural safety at policy, professional and practice levels. This paper ends by drawing implications for Indigenous social work education and training, Indigenous social policies and further research.
