Increasingly, clinicians are required to utilize effec- tive and efficient treatments for mental health problems. Publicly funded systems are often faced with constraints on the range and amount of service that they can provide, while privately funded services seek to con- trol costs in order to maximize shareholder profits. In both contexts, the ability to identify and implement effective and time-limited treatments is considered a benefit, and thus practice guidelines have evolved to favor such approaches. Mental health practice guidelines have included cognitive-behav- ioral therapy as a psychological treatment of choice for many different problems, as it has been shown to be an effective and efficient approach. Consequently, many students and practitioners seek training in cognitive- behavioral therapy. They also want to understand how the results of psy- chotherapy outcome and process research apply to practice. If a treat- ment is “evidence based,” how does that evidence translate into clinical practice? What specifics of practice are supported by research findings? Conversely, what are the limits of our knowledge, and what are the areas where clinical judgment and sound ethical reasoning must guide clinicians’ behavior? This second edition of Evidence-Based Practice of Cognitive-Behavioral Therapy attempts to answer these questions and to bridge the gap between practice and research, as well as to highlight innovations and updates in the field. While many texts have been written on cognitive-behavioral ther- apy, very few of them have addressed this therapy from the perspectives of practice, science, and the systems within which they are embedded. The trend within the field has been to focus on specific problem areas, diagnostic conditions, and/or specialized types of therapy. As a result, we increasingly know which interventions work for which problems, vii viii Preface and yet relatively little has been written about transdiagnostic cognitive- behavioral therapy applications that can guide the clinician. There is much that is similar about various applications of cognitive-behavioral therapy, and this book describes “common factors” in assessment, inter- vention, and consultation. Indeed, many aspects of this treatment have become mainstream and are assumed to be best practice; this book also explores the empirical support behind them. We also identify areas where the evidence lags behind practice, both to make practitioners aware of them and to promote research to address critical questions. In addition, we identify a number of myths about cognitive-behavioral therapy to provide readers with a sense of our perspective on the field. This book will be particularly useful to people who are in the process of discovering cognitive-behavioral therapy, including graduate students and interns in clinical and counseling psychology, residents in psychiatry, trainees in other mental health disciplines, and new practitioners. Based on feedback we received on the first edition, even seasoned psychothera- pists may find useful reinforcement of their ideas here, or discover “nug- gets” to integrate into their practice. In this text, we have worked to be as practical as possible, and to make links to practice based on the best available evidence. This book reflects an attempt to integrate the best of science with the realities of clinical practice. We have tried to be both practical and realistic about what cognitive-behavioral therapy can provide. All of the chapters that focus on practice discuss their respective topics and provide examples and case materials. We regularly make reference to clients to illustrate particular concepts or techniques. We have also used the ficti- tious therapy case of “Stephen” as a running illustration of the applica- tion of cognitive-behavioral therapy from assessment to completion of treatment. None of the clients in this book is an exact portrayal of a real person; rather, they represent edited, composite, fictionalized representa- tions of cases and situations we have encountered. As many clients are not “textbook” cases, and all therapists run into difficulties, we discuss some of the common challenges encountered in practice and have pro- vided numerous suggestions to address these challenges. In contrast to the more practical chapters of the book, the final chap- ter takes a step back from the application of cognitive-behavioral ther- apy with individuals in order to examine some of the contextual issues that surround this psychotherapeutic approach, as well as the outcome research base. It is difficult for practitioners to have the time and energy to review the research literature, and so we summarize this literature and review the key meta-analytic studies that have been published since the first edition of this text.
