This book provides an overview of theories for direct social work practice and a framework for integrating the use of theory with central social work principles and values, as well as with the artistic elements of practice. It is intended primarily for graduate-level social work students and practitioners. The book has similarities to other books that provide surveys of clinical theories for social work practice; however, the authors think it has a number of distinctive and useful features. In brief, these features include: (a) grounding direct practice specialization firmly in the generalist perspective of social work practice; (b) documenting the trend toward, and rationale and empirical support for, eclecticism in the broad field of counseling/psychotherapy, and reviewing various approaches to eclecticism; (c) bringing order to, and demystifying theories by differentiating among levels of theory, organizing direct practice theories into like groupings, and providing an overview of the central characteristics of each grouping of theories; (d) providing a critical perspective on the dominant, scientific paradigm of direct practice that centers the use of theory and technique, and putting equal emphasis on the artistic elements of practice; and (e) proposing the problem-solving model as a useful structure for facilitating the integration of the artistic and scientific elements of practice. The contents of all of the chapters in this fourth edition have been revised and updated to reflect developments in theory, practice, and research since the second edition was published. In Part II of the book there is a new chapter on couples theory and intervention, as an additional metatheory for social work practice. In Part III, there are now chapters on trauma informed practice, motivational interviewing, anti-oppressive theory, mindfulness-based practices, eye movement desensitation and reprossessing and dialectical behavior therapy.
