It was the spring of 1981. Over the previous eight months, the Philadelphia Phillies had won the World Series, and the Eagles, Sixers, and Flyers had made it to the Super Bowl, NBA Finals, and Stanley Cup Finals, respectively. I had two adorable children aged 5 and 3. I had been granted tenure at Princeton. My life was full—or so I thought.

Then, Linda Chaput, at that time an editor at W. H. Freeman and Company and Worth Publishers, walked into my office. During a lively discussion, she and I discovered that we had similar ideas about how abnormal psychology should be presented in a textbook. By the time Linda departed 2 hours later, we had outlined the principles that should underlie the “ideal” abnormal psychology textbook. We had, in effect, a deal. All that was left was for me to write the book. A decade later, the first edition of Abnormal Psychology (“the BOOK,” as my family and I had come to call it) was published.

As I look back to that fateful day in 1981, I cannot help but note that several things have changed. With a few exceptions, my Philadelphia sports teams have returned to form and struggled year in, year out. My sons have become accomplished middle-aged men, and their previous “adorable” tag is now worn by my 1-year-old and 3-year-old grandchildren, Emmett and Delia. I am older, humbler, and a bit more fatigued than the person who met with Linda Chaput 34 years ago.

At the same time, several wonderful things remain the same. I am still at Princeton University. I am still married to the same near-perfect person—Marlene Comer. And I still have the privilege of writing abnormal psychology textbooks—Abnormal Psychology and Fundamentals of Abnormal Psychology. The current version, Abnormal Psychology, Ninth Edition, represents my seventeenth edition of one or the other of the textbooks.

My textbook journey has been a labor of love, but I also must admit that each edition requires enormous effort, ridiculous pressure, and too many sleepless nights to count. I mention these labors not only because I am a world-class whiner but also to emphasize that I approach each edition as a totally new undertaking rather than as a cut-and-paste update of past editions. I work feverishly to make each edition fresh and to include innovative and enlightening pedagogical techniques.

With this in mind, I have added an enormous amount of new material and many exciting new features for this edition of Abnormal Psychology—while at the same time retaining the successful themes, material, and techniques that have been embraced enthusiastically by past readers. The result is, I believe, a book that will excite readers and speak to them and their times. I have again tried to convey my passion for the field of abnormal psychology, and I have built on the generous feedback of my colleagues in this undertaking—the students and professors who have used this textbook over the years.

In line with the many changes that have occurred over the past several years in the fields of abnormal psychology, education, and publishing, and in the world, I have brought the following new features and changes to the current edition.

•NEW• DSM-5With the publication of DSM-5, abnormal psychology is clearly a field in transition. To help students appreciate the field’s current status and new directions, I present, integrate, and analyze DSM-5 material throughout the textbook. Controversy aside, this is now the field’s classification and diagnostic system, and it is important that readers understand and master its categories and criteria, appreciate its strengths and weaknesses, and recognize its assumptions and implications, just as past readers learned about the categories, quality, and implications of previous DSM editions.

xvii

DSM-5, as well as discussions of its implications and controversial nature, is presented in various ways throughout my textbook. First, its new categories, criteria, and information are woven smoothly into the narrative of each and every chapter. Second, reader-friendly pedagogical tools throughout the textbook, including a two-page infographic on the inside front cover and regular short features called Dx Checklist and DSM-5 Controversy, help students fully grasp the DSM-5 material. Third, special topic boxes highlight DSM-5 issues and controversies, such as Premenstrual Dysphoric Disorder: Déjà Vu All Over Again (page 238) and What Happened to Asperger’s Disorder? (page 589).

•NEW• REORGANIZATION OF TWO KEY CHAPTERSTwo chapters in this new edition of Abnormal Psychology have been restructured, partly to be consistent with certain DSM-5 changes, but more important because this reorganization helps the material to unfold in a more logical way for readers. All psychological disorders in which somatic symptoms are key features are now grouped together in Chapter 10, Disorders Featuring Somatic Symptoms. This chapter includes factitious disorder, conversion disorder, somatic symptom disorder, illness anxiety disorder, and psychological factors affecting other medical conditions. Psychological disorders that are triggered by extraordinary trauma and stress are now grouped together in Chapter 6, Disorders of Trauma and Stress. This chapter includes the trauma- and stressor-related disorders (acute stress disorder, posttraumatic stress disorder, and adjustment disorders) and the dissociative disorders (dissociative amnesia, dissociative identity disorder, and depersonalization-derealization disorder).

•NEW• TECHNOLOGY AND THE MINDTECH FEATUREThe breathtaking rate of technological change that characterizes today’s world has had significant effects on the mental health field. In this edition I cover this impact extensively in many discussions in the book’s narrative, boxes, photographs, and figures. The book examines, for example, how the Internet, texting, and social networks have become convenient tools for those who wish to bully others or pursue pedophilic desires (pages 565–566, 576); how social networking may provide a new source for social anxiety (page 155); and how today’s technology has helped create new psychological disorders such as Internet addiction (pages 420, 660–662). It also looks at dangerous new trends such as the posting of self-cutting videos on the Internet (page 288). And it informs the reader about cybertherapy in its ever-expanding forms—from Skype therapy to avatar therapy to virtual reality treatments (pages 75, 84, 193).

I have added a new feature throughout the book called MindTech—sections in each chapter that give special attention to particularly provocative technological trends in engaging and enlightening ways. The MindTech features examine the following cutting-edge topics:

•NEW• INFOCENTRALS:It is impossible to surf the Internet, watch TV, or flip through a magazine without coming across infographics, those graphic representations that present complex data in quick, stimulating, and visually appealing ways. Infographics present information in a way that allows us to easily recognize trends and patterns and make connections between related concepts. With the development of new digital tools over the past decade, the popularity of infographics has exploded. Readers and viewers like them and learn from them.

Thus Abnormal Psychology, Ninth Edition, introduces a new feature called Info- Central—numerous, lively infographics on important topics in the field. The infographics provide visual representations of data related to key topics and concepts in each chapter, offering fascinating snippets of information to spur the readers’ interest. I am certain that readers will greatly enjoy these special offerings, while also learning from them.

Every chapter features a full-page InfoCentral, including the following ones:

xix

•NEW• ADDITIONAL “CUTTING EDGE” BOXESI have grouped the book’s other boxes into two categories: PsychWatch boxes examine text topics in more depth, emphasize the effect of culture on mental disorders and treatment, and explore examples of abnormal psychology in movies, the news, and the real world. MediaSpeak boxes offer provocative pieces by news, magazine, and Web writers and bloggers on current issues in abnormal psychology. In addition to updating the PsychWatch and MediaSpeak boxes that have been retained from the previous edition, I have added many new ones. For example, new MediaSpeak boxes include the following:

•NEW• CLINICAL CHOICES INTERACTIVE CASE STUDIESThis ninth edition of Abnormal Psychology includes 11 new interactive case studies (one for each of the disorders chapters), available online through LaunchPad, our online course-management system. Through an immersive mix of video, audio, and assessment, each interactive case allows the student to simulate the thought process of a clinician by identifying and evaluating a virtual “client’s” symptoms, gathering information about the client’s life situation and family history, determining a diagnosis, and formulating a treatment plan. The student will also answer various questions about each case to help reinforce the chapter material. Each answer will trigger feedback, guidance, and critical thinking in an active-learning environment.

•NEW• ADDITIONAL AND EXPANDED TEXT SECTIONSOver the past few years, a number of topics in abnormal psychology have received special attention. In this edition, I have provided new sections on such topics, including the psychology of mass killings (page 534); the impact of the Affordable Care Act (pages 22, 659); the growing role of IRBs (pages 49–51); dimensional diagnoses (pages 520–522); new treatments in the field (pages 44, 260, 506); spirituality and mental health (page 79); overuse or misuse of certain diagnoses (pages 212, 522); the psychological price of celebrity (pages 229, 295–296); transgender issues (pages 456–457); alternative views of personality disorders (pages 555–559); imprisonment and psychological functioning (page 644); self-injury (page 288); the pro-Ana movement (page 361); poor medical treatment for people with psychological disorders (page 340); culture and abnormality (pages 116, 554–555); race and the clinical field (page 132); and sexism in the clinical field (pages 238, 443).

•NEW• NEW CASE MATERIALOne of the hallmarks of my textbooks is the inclusion of numerous and culturally diverse clinical examples that bring theoretical and clinical issues to life. In my continuing quest for relevance to the reader and to today’s world, I have replaced or revised more than one-third of the clinical material in this edition. The new clinical material includes the cases of Franco, major depressive disorder (pages 97, 100, 113, 120); Tonya, Munchausen syndrome by proxy (page 320); Meri, major depressive disorder (page 217); Eduardo, paranoid personality disorder (pages 522–523), Luisa, dissociative personality disorder (page 200); Kay, bipolar disorder (page 278); Shani, anorexia nervosa (page 352); Ricky, ADHD (pages 563–564); Lucinda, histrionic personality disorder (pages 541–542); Jonah, separation anxiety disorder (pages 567–568); Sam, voyeuristic disorder (page 451); and many others.

•NEW• CRITICAL THOUGHT QUESTIONSThe “critical thought questions” were a very stimulating feature of my previous edition of Abnormal Psychology. These questions pop up within the text narrative, asking students to pause at precisely the right moment and think critically about the material they have just read. Given the enthusiastic response to this feature by professors and readers alike, I have added many new critical thought questions throughout the textbook, including in every MindTech and MediaSpeak feature.

xx

•NEW• “BETWEEN THE LINES”The textbook not only retains but expands a fun and thought-provoking feature from past editions that has been very popular among students and professors—the reader-friendly elements called Between the Lines, which consist of text-relevant tidbits, surprising facts, current events, historical notes, interesting trends, and enjoyable lists and quotes.

•NEW• THOROUGH UPDATEIn this edition I present the most current theories, research, and events, including more than 2,000 new references from the years 2012–2014, as well as hundreds of new photos, tables, and figures.

•EXPANDED COVERAGE• PREVENTION AND MENTAL HEALTH PROMOTIONIn accord with the clinical field’s growing emphasis on prevention, positive psychology, and psychological wellness, I have increased significantly the textbook’s attention to these important approaches (for example, pages 19–21).

•EXPANDED COVERAGE• MULTICULTURAL ISSUESOver the past 30 years, clinical theorists and researchers increasingly have become interested in ethnic, racial, gender, and other cultural factors, and my previous editions of Abnormal Psychology certainly have included these important factors. In the twenty-first century, however, the study of such factors has, appropriately, been elevated to a broad perspective—the multicultural perspective. Consistent with this clinical movement, the current edition includes yet additional multicultural material and research throughout the text. Even a quick look through the pages of this textbook will reveal that it truly reflects the diversity of our society and of the field of abnormal psychology.

•EXPANDED COVERAGE• “NEW WAVE” COGNITIVE AND COGNITIVE-BEHAVIORAL THEORIES AND TREATMENTSThe current edition of Abnormal Psychology has expanded its coverage of the “new wave” cognitive and cognitive-behavioral theories and therapies, including mindfulness-based cognitive therapy and Acceptance and Commitment Therapy (ACT), presenting their propositions, techniques, and research in chapters throughout the text (for example, pages 74, 139, 261, 343).

•EXPANDED COVERAGE• NEUROSCIENCEThe twenty-first century has witnessed the continued growth and impact of remarkable brain-imaging techniques, genetic mapping strategies, and other neuroscience approaches, all of which are expanding our understanding of the brain. Correspondingly, the new edition of Abnormal Psychology has further expanded its coverage of how biochemical factors, brain structure, brain function, and genetic factors contribute to abnormal behavior (for example, pages 57–60, 143, 222–226).

As I noted earlier, in this edition I have also retained the themes, material, and techniques that have worked successfully and been embraced enthusiastically by past readers.

BREADTH AND BALANCEThe field’s many theories, studies, disorders, and treatments are presented completely and accurately. All major models—psychological, biological, and sociocultural—receive objective, balanced, up-to-date coverage, without bias toward any single approach.

xxi

INTEGRATION OF MODELSDiscussions throughout the text, particularly those headed “Putting It Together,” help students better understand where and how the various models work together and how they differ.

EMPATHYThe subject of abnormal psychology is people—very often people in great pain. I have tried therefore to write always with empathy and to impart this awareness to students.

INTEGRATED COVERAGE OF TREATMENTDiscussions of treatment are presented throughout the book. In addition to a complete overview of treatment in the opening chapters, each of the pathology chapters includes a full discussion of relevant treatment approaches.

RICH CASE MATERIALAs I mentioned earlier, the textbook features hundreds of culturally diverse clinical examples to bring theoretical and clinical issues to life. More than 25 percent of the clinical material in this edition is new or revised significantly.

MARGIN GLOSSARYHundreds of key words are defined in the margins of pages on which the words appear. In addition, a traditional glossary is available at the back of the book.

“PUTTING IT TOGETHER”A section toward the end of each chapter, “Putting It Together,” asks whether competing models can work together in a more integrated approach and also summarizes where the field now stands and where it may be going.

FOCUS ON CRITICAL THINKINGThe textbook provides tools for thinking critically about abnormal psychology. As I mentioned earlier, in this edition, “critical thought” questions appear at carefully selected locations within the text discussions. The questions ask readers to stop and think critically about the material they have just read.

STRIKING PHOTOS AND STIMULATING ILLUSTRATIONSConcepts, disorders, treatments, and applications are brought to life for the reader with stunning photographs, diagrams, graphs, and anatomical figures. All of the figures, graphs, and tables, many new to this edition, reflect the most up-to-date data available. The photos range from historical to today’s world to pop culture. They do more than just illustrate topics: they touch and move readers.

ADAPTABILITYChapters are self-contained, so they can be assigned in any order that makes sense to the professor.

SupplementsI have been delighted by the enthusiastic responses of both professors and students to the supplements that accompany my textbooks. This edition offers those supplements once again, revised and enhanced, and adds a number of exciting new ones.

I also extend my deep appreciation to the core team of professionals at Worth Publishers and W. H. Freeman and Company who have worked so closely with me to produce this edition and many previous editions. The book’s development editor, Mimi Melek, to whom I have dedicated this book, is simply the hardest-working and smartest person I know. Her work on this textbook has been truly beyond description, so I won’t even try to describe it. Suffice it to say, she is the best, and I am more than fortunate that she has been the senior editor for this and the last several editions of my textbooks. She has also become a dear friend. Similarly, the rest of my Worth core team consists of truly extraordinary people—each extremely talented, each committed to excellence, each dedicated to the education of readers, each bound by a remarkable work ethic, and each a wonderful person. It is accurate to say that these members of the core team were once again my coauthors and co-teachers in this enterprise, and I am in their debt. They are Rachel Losh, publisher; Daniel McDonough, executive acquisitions editor; Tracey Kuehn, director of editing, design, and media production for the sciences and social sciences, Jane O’Neill, senior project editor; Sarah Segal, production manager; Paul Lacy, layout designer; Jennifer Atkins, photo editor; Lauren Samuelson, media editor; Babs Reingold, cover and interior designer; Diana Blume, art director; and Chuck Yuen, infographic designer.

I also am indebted to Kevin Feyen, vice president, digital product development, and Catherine Woods, vice president, editing, design, and media production, who have been involved with my books for many years. Still other professionals at Worth and at Freeman to whom I am indebted are Lisa Kinne, managing editor; Todd Elder, director of advertising; Kimberly Morgan, editorial assistant; Katherine Garrett, assistant editor; Melissa Rostek, editorial intern; Hilary Newman, director of rights and permissions; Melissa Pellerano and Felicia Ruocco, permissions editors; Anna Paganelli, copy editor; Ellen Brennan and Marlene Glissmann, indexers; and John Philp, for his outstanding work on the video supplements for professors and students. Not to be overlooked are the superb professionals at Worth and at Freeman who continuously work with great passion, skill, and judgment to bring my books to the attention of professors across the world: Kate Nurre, executive marketing manager; Lindsay Johnson, senior marketing manager; Allison Greco, marketing assistant; Craig Bleyer, national sales manager; and the company’s wonderful sales representatives. Thank you so much.

One final note. As I mentioned in the prefaces of the past few editions, with each passing year I have become increasingly aware of just how fortunate I am. So, once again, at the risk of sounding like a walking cliché, let me say with a clarity that at the age of 67 is sharper and better informed than at earlier points in my life, how appreciative I am that I have the opportunity each day to work with so many interesting and stimulating students during this important and exciting stage of their lives. Similarly, I am grateful beyond words for my extraordinary family, particularly my wonderful sons, Greg and Jon; my fantastic daughters-in-law, Emily and Jami; my perfect grandchildren, Delia and Emmett; and my truly magnificent wife, Marlene.
