Book excerpt: Reaffirms the importance of the larger kinship network through analysis of extensive data on the clients of one social agency. The authors show that the less kinship-oriented caseworkers often attempt to change clients' kin relationships in the direction of less involvement, raising questions about value differences in therapeutic practice. The book also points to the importance of concepts, such as those dealing with family kinship, that will enable the caseworker to appraise the client's social relationships more fully. The authors emphasize the benefits to be derived from a closer liaison between social work and social science.
