A “separated family” refers to a family where couples are forced to work outside home away from each other due to financial reason, and families of sailors are one of the examples. These families have alienated parent-child relationships, and the husband and wife are often apart from each other. Under this scenario, how these parents discipline their children and the interaction between the sailor’s family members draw curiosity. In this study, the semi-structured interview method used in qualitative research was adopted in order to explore the sailors’ performance in three aspects: parenting agreement, support and suppression, and involvement in family matters. It was found that the mode of one parent being strict and the other being lenient brought out wonderful performance in the parent-child interaction. Due to the special family bonding, the children demonstrated special independence. On parenting ideas, the father generally followed the mother’s ideas. The father that was often not around showed his concern and love for the family through every message sent and every meeting. Based on the study results, recommendations related to the sailor parent's way to discipline his children were proposed in order to create better parent-child interaction.
