This comprehensive reference integrates and covers the most widely used psychotherapy approaches. Each of the four volumes covers theoretical underpinnings of the therapeutic modality for the major populations (children, adults, couples and families) and addresses the major psychological and emotional disturbances that the psychotherapy model is most effective in treating. The four-volume set combines established and cutting-edge authors and issues, as well as integrating material for both novice and experienced theorists, researchers and practitioners. This volume illustrates the many ways in which different theoretical models are integrated to better serve clients. Contributors to this volume provide state-of-the-art coverage of what is currently being done, and in what direction future conceptualization, research and practice are likely to proceed in integrative/eclectic therapy.
