Eysenck (1957) concluded that “the figures fail to support the hypothesis that psychotherapy facilitates recovery from neurotic disorder” (p. 322), but by 1977 Smith and Glass could conclude, after reviewing 375 studies, that “findings showed psychotherapy to be effective” (p. 752). Over the next 35 years interest in psychotherapy outcomes research flourished and is no mere idle academic question, but an issue for public policy, and now directs the expenditures of public health monies on a national scale in some countries. Currently, professional organizations, such as the American Psychological Association, and national organizations, such as the United Kingdom’s National Institute of Clinical Excellence (NICE), periodically publish lists of therapies that meet standards for evidence-based practice; the NICE goes further and influences national spending and professional training in disseminating and evaluating evidence-based practices in large-scale routine service settings. Psychotherapy outcome research has come a long way since Eysenck’s dystopic conclusion.

This first volume of Handbook of Evidence-Based Practice in Clinical Psychology shows that in the area of child and adolescent disorders there has been much progress in identifying and disseminating evidence-based practices. Each chapter documents the large amount of research that now identifies evidence-based practices for most disorders. To be sure, some disorders have very large evidence bases that permit greater confidence in conclusions and answers to more specific questions, such as which of several treatments might be most effective; others have more modest databases, permitting only modest and less certain conclusions.

Various forms of cognitive behavior therapy predominate as evidence-based practices, although in other areas—such as intellectual disabilities, autism spectrum disorders, and pica—behavioral treatments alone are at the forefront. For some disorders, certain forms of psychotherapy, such as interpersonal psychotherapy, meet the criteria for evidence-based practice. As evidence continues to accumulate these conclusions may change.

This volume is in two parts. Part I of this volume addresses general issues such as what the standards of evidence are, professional issues, and economics of evidence-based practice. Part II addresses many specific disorders of childhood and adolescence.

We believe that this volume presents a snapshot of an ever-developing field. It provides therapists, teachers, students, and other practitioners a starting point to become familiar with evidence-based practice in clinical psychology. It challenges psychology teachers to see if they teach evidence-based psychotherapies and also challenges service providers and finders to examine their own practices to see if they provide evidence-based practice.

We would first like to thank our authors. Many of them undertook an enormous task of summarizing sometimes hundreds of articles, systematic literature reviews, and consensus panels and at times reviewing the outcome literature for many different forms of treatment for one disorder. They faced the challenge of being accurate and fair in identifying those practices that the literature support, those that researchers have little convincing evidence to support, and those that research has shown to be ineffective or harmful. We believe they all succeeded in doing so. We would both like to express our unending thanks to Carole Londeree’s persistent and cheerful technical assistance throughout this project. Finally, we would like to express our thanks to the editorial staff at John Wiley & Sons who worked so hard to make this project a success.

Rationale and Standards of Evidence in Evidence-Based Practice


What is the purpose of collecting evidence to inform clinical practice in psychology concerning the effects of psychological or other interventions? To quote Paul’s (1967) article that has been cited 330 times before November 4, 2008, it is to determine the answer to the question: “What treatment, by whom, is most effective for this individual with that specific problem, under which set of circumstances?” (p. 111). Another answer is pitched at a systemic level, rather than concerning individuals. That is, research evidence can inform health-care professionals and consumers about psychological and behavioral interventions that are more effective than pharmacological treatments, and to improve the overall quality and cost-effectiveness of psychological health service provision (American Psychological Association [APA] Presidential Task Force on Evidence-Based Practice, 2006). The most general answer is that research evidence can be used to improve outcomes for clients, service providers, and society in general.
