[영문]This paper reports on empirical research involving focus groups with social workers in order to provide insight into their experiences of working with lone white mothers of mixed-parentage children in England. Social workers understandings of key areas of families lives are explored, including experiences of racism and adequacy of social support networks. The analysis highlights the need for a greater awareness of racism and social disapproval experienced by mothers, and how this impacts upon their support networks. The contested areas of identity and social and political identification for mixed-parentage children are discussed and key questions are asked about the use of terminology and how this influences social work practice. This paper also considers how social workers felt services could be improved and highlights the need for further training.
