The foster family is an important and indispensable form of care in the protective placement system for children and adolescents. With professional development, foster caregivers have made progress from being charitable roles to semi-professional ones. The purpose of this research is to explore how female foster caregivers understand their role as foster caregivers. Under the context of self-positioning as a foster caregiver, it is hoped that the potential issues can be identified during the implementation of the current foster care placement process. This research used the qualitative research method to conduct in-depth interviews with 8 female foster caregivers who had cared for abused children in the past three years. The results of the study found that: (1)self-role awareness of foster caregivers can be categorized as the following four roles: emotional, therapeutic, parenting, and contradictory. (2)Role fragility upon practicing: In response to the dilemma of care, it was misunderstood by social workers as being insufficiently tolerant of children, limited control rights in the care relationship, only the entrusted caregivers placing decision-making outsiders, being excluded from the school system and entering the unfavorable ecology of children Environment. A foster caregiver is a compound role. In addition to the public welfare, semi-professional, and contractual care roles constructed in the society and the system, a maternal role a female foster caregiver develops may be the most neglected role in the placement system. In response to the above-mentioned research findings, reflections and suggestions are proposed, including the nature of a foster care role, the welfare of foster children, and the existing delivery system of foster care placement services.
