This research revealed the summary of results as below: By following the time sequence, there were six stages including ”preparation and cultivation”, ”obscure paternal concept”, ”impact and confusion”, ”buffer for adaptation to paternal role”, ”caring for child's living condition”, and ”development of parenting role” during the first year paternal experience. Furthermore, the emphasis and paternal connotation were different. Based on the results, this research provided suggestions in planning of parent education for the first-time fathers and future research.
