This welcome new edition of a best-selling text offers a comprehensive survey of major theories relevant to social work practice and a clear assessment of the role and value of each approach based on the current critical literature. The book builds on the strength of the previous editions, with a major recasting of the first two chapters to bring them up to date, a wholly new chapter on feminist theory, and a greater emphasis on applying theory to practice. Taken together, the revisions will secure the continuing value of this world-class textbook as an invaluable companion for social work students and educators alike.
