Purpose: Competency is a key foundation of the nursing education curriculum and a baseline element of nursing practice. The purpose of this study was to explore the competencies of community health nurses in a maternal early childhood sustained home-visiting program based on nurses’ field experiences. Methods: The participants were 21 nurses who had more than 1 year of experience in this program. Reflective interviews were performed; lasting 1 hour per nurse, on August 18, 2016, and the collected data were analyzed using qualitative directed content analysis. Results: Twenty-four themes were extracted for 9 competencies. The major themes included implementing a long-term relationship-based approach, providing client-led service rather than expert-led service, helping mothers with psychosocial difficulties, and applying skills in a practical manner in the home environment. Conclusion: In order to develop a home-visiting program as part of maternal-early childhood nursing practice, nurses should develop com-petencies that help them make significant and positive interventions. Results indicate that the curriculum for commun-ity health nurses should be changed to improve competencies in building relationships with clients and to focus on the application of skills in specific cases and in clinical practice.
