We dedicate this work to the key theorists of the cognitive behavior therapies discussed in this book. Each pioneer has had a profound impact on the foundation and evolution of evidence-based counseling approaches.

As a result of their innovative work, countless numbers of people of all ages are able to apply the principles to themselves to enhance their emotional well-being.

The term cognitive behavior therapy (CBT) is familiar to most mental health practitioners throughout the world. As you will read in the first chapter, CBT is a generic term that describes a wide range of approaches, despite the misconception that there is one type of CBT. As O' Kelly (2010) noted, CBT is “like a river” with many tributaries, including classical and operant conditioning and learning theory, among other influences, and the premise that cognitions trigger emotional and behavioral reactions (p. 10). Albert Ellis and Aaron Beck were at the forefront of the cognitive revolution, which has steadily gained momentum and popularity over the years in part because the various CBT approaches have wide applicability and have been shown to be effective with many different types of presenting problems. Furthermore, CBT readily lends itself to a broad array of interventions that are practical in nature and have been proven to effect change.

The authors of these chapters are experts in this field, both as practitioners and as scholars. They provide a comprehensive overview of the following theories: behavior therapy, cognitive therapy, rational emotive behavior therapy, multimodal behavior therapy, acceptance and commitment therapy, dialectical behavior therapy, and mindfulness. They address pertinent information pertaining to the key theorist or theorists associated with the theory as well as give an overview of the basic principles of that theory. In addition, they describe the therapeutic process, with an emphasis on the process of change and specific interventions associated with the theory. Applications and efficacy are also addressed. At the end of each chapter, the authors include a verbatim transcript of an actual counseling session so that you will have a better idea of how the theory works in practice. These transcripts are from a fourth session, with some background about the client and issues addressed in previous sessions. Each author also provides a short critique of why the theory is effective in addressing the problem and what went well or could have been done differently. Clients' names and identifying information for these transcripts have been modified to protect their identities. The final chapter considers the case of Marcos, contributed by Anthony Pantaleno, who coauthors the chapter on mindfulness. After a description of the case, the authors who discussed each respective theory describe how they would conceptualize this case, including the establishment of the therapeutic alliance, goal setting, the process of change, and interventions to address the targeted issues.

As coeditors and contributing authors, we hope that this book enlightens students and practitioners about the various forms of CBT, dispelling myths and misconceptions. We hope that the emphasis on practical information, further illustrated through the verbatim case examples and the case of Marcos, contributes to a broader understanding of the “what' s” and “how to' s” of the seven theories addressed in this book.
