She is a licensed clinical psychologist with a specialization in behavior therapy. She has held positions as visiting professor at the University of Pittsburgh (1985–87) and as professor of clinical psychology at Humboldt University, Berlin (1993– 2000). Since 2000 she has served as Scientific Director of the Department of Neuropsychology and Clinical Psychology at the Central Institute of Mental Health and as a full professor at the University of Heidelberg. She has made important discoveries in the field of pain and phantom phenomena, including the cortical processing of pain-related information in humans. Her research focuses on the interaction of brain and behavior, in particular the question of how behavior and experience influence neural processes and how neural processes alter behavior and experience. A special interest is in the role of implicit learning and memory processes in the development and maintenance of chronic pain, tinnitus, anxiety disorders, addiction, and depression. The methods she has used range from experimental psychology to non-invasive brain imaging and peripheral psychophysiology. She is also actively involved in the development of new behavioral approaches to pain and other mental disorders and teaches and supervises clinical psychologists in cognitive-behavioral methods. She has published more than 300 scholarly articles and has received several awards and honors, which include the Award for Basic Research of the State of Baden-Württemberg (2004), the German Psychology Award (2002), the Muscle Pain Research Award (2001), the Max-Planck-Award for International Cooperation (2000), and the German Pain Research Prize (1992 and 2000).

Foreword To be in physical pain is to find yourself in a different realm—a state of being unlike any other, a magic mountain as far removed from the familiar world as a dreamscape. Usually, pain subsides, one wakes from it as from a nightmare, trying to forget it as quickly as possible. But what of pain that persists? The longer it endures, the more excruciating the exile becomes. Will you ever go home? you begin to wonder, home to your normal body, thoughts, life? Melanie Thernstrom, The Pain Chronicles: Cures, Myths, Mysteries, Prayers, Diaries, Brain Scans, Healing and the Science of Suffering (New York: Farrar, Straus and Giroux; 2010, p. 3)
According to the recently published report from the Institute of Medicine, “Relieving pain: a blueprint for transforming pain prevention, care, education and research” (2011), as many as 116 million adult Americans suffer from common chronic pain conditions at an estimated cost of between $560 and $630 billion annually for health care expenses and lost productivity. Pain affects everyone, and the toll of chronic pain on one’s sense of self and wellbeing, on physical functioning, and on overall quality of life can be devastating. The IOM report integrates the voices of persons living with chronic pain to highlight the anguish of unremitting pain, helplessness and hopelessness, and the travails of the unsuccessful search for relief. The quote above from author Melanie Thernstrom, a member of the IOM Committee that prepared the report and herself a person with chronic pain, provides a glimpse of the personal horrors of life with persistent pain, particularly the prospect of pain without end. Advances in understanding of the mechanisms that promote the development of chronic pain and that sustain it have been rapid in the past several decades, and an increasing array of effective therapies have been identified. These therapies span pharmacological, interventional, behavioral, and rehabilitation strategies, as well as a growing number of evidence-based complementary and alternative approaches. Yet millions continue to suffer due to a limited response to therapy or because of barriers to accessing appropriate care. The IOM report calls for a comprehensive approach to meet the moral imperative to eliminate these barriers xi

Foreword
through substantial investments in prevention, novel therapies, education for health care professionals and the public, and research. A major challenge facing the field of pain management is the need to expand efforts to educate and train health care providers in the use of evidence-based clinical assessment and therapeutic approaches. This is a tough challenge as the science of pain and pain management continues to expand at an enormous rate, making it difficult for educators and future providers to maintain an up-to-date knowledge of these advances and to build and maintain clinical competencies. Expansion of formal education and training programs in pain management is clearly needed, and opportunities for continuing education need to be increased in number and scope. Chronic Pain: An Integrated Biobehavioral Approach, by Herta Flor and Dennis C. Turk, two of the leading scientists and scholars in our field, offers in a single volume the most comprehensive and in-depth view of the field currently available. Drs. Flor and Turk share their collective knowledge and professional insights accumulated over three decades of extraordinary contributions to the field. The book provides a compelling case in support of an integrative approach to clinical assessment and management of chronic pain that draws upon the state-of-the-science from the diverse field of pain management that extends from clinical neuroscience to translational behavioral medicine science. The first section provides an up-to-date and highly digestible review of the foundational principles of the multidimensional experience of chronic pain and is followed by two sections on clinical assessment and treatment, concluding with a glimpse at future innovations in pain care. These later sections are simply extraordinary in integrating theory, science, and practical information that will be equally useful to novice and experienced clinicians, investigators, and policy makers. Ultimately, this text promises to stand alone as the single best source for educators and for those seeking to expand their knowledge of the field of chronic pain management. I applaud this exciting addition to our armamentarium in meeting the challenges of the IOM and furthering our collective efforts to help relieve unnecessary pain and suffering. Robert D.

Preface This volume provides a psychobiological perspective on people who experience chronic pain and describes a comprehensive approach to their treatment. The text focuses on the interaction of psychosocial (psychological, behavioral, and social) and physiological processes in people with chronic pain and the implications that follow. In recent years, there has been growing recognition that neither purely somatic nor completely psychological models by themselves are adequate to explain the subjective experience of chronic pain and associated disability. Our basic hypothesis is that chronic pain is a learned response, whereby “pain memories” rather than current nociceptive input determine much of the pain experienced. Moreover, interdisciplinary approaches that integrate psychological principles and approaches with traditional biomedical knowledge in the assessment and treatment of people with chronic pain are more fruitful than any single modalities, be they physical (surgery, medication, regional anesthesia, or neuroaugmentive interventions) or psychological (biofeedback, counseling, or psychotherapy). Integration of current psychological information and principles with existing biomedical knowledge will increase our understanding of people with various chronic pain syndromes and should lead to more effective treatment outcomes and improved quality of life for those with persistent pain. Although our emphasis is on the role of psychological and social factors in chronic pain states, we attempt to integrate these aspects with the current biological understanding of the neurophysiology of nociception. In the introductory section we provide a theoretical framework that is essential for understanding, evaluating, and successfully treating the person with chronic pain and not just the pain. We give special emphasis to learning and cognitive processes (beliefs, anticipation, subjective meaning, and memory) that determine how pain is experienced. In the second section, we focus on a comprehensive approach to assessment. We outline our concept of multiaxial assessment and guide xiii

the reader through the process of achieving a differential diagnosis that serves as the basis for decision making and treatment planning. We provide a detailed discussion of the rationale behind and the components of comprehensive assessment. We include specific recommendations for using a set of assessment procedures, including interviews, self-report questionnaires, behavioral observation schemes, and psychophysiological methods. We provide a general assessment algorithm and recommend specific methods that will form the basis for a comprehensive evaluation of the chronic pain patient. In the final section, we outline three well-validated treatment approaches that have received the greatest amount of empirical support in pain management: biofeedback and relaxation training, operant group treatment, and cognitive-behavioral pain management. We also focus on newer treatment methods that are based on findings of learning-related maladaptive plastic reorganization of the brain secondary to the experience of pain. These insights open the avenue to innovative approaches that may be incorporated in the treatment of chronic pain patients. We will not provide an exhaustive review of the vast pain literature, but rather emphasize our own empirically based view of the best evidence-based approaches to the treatment of chronic pain patients. In our discussion of treatments, we describe the rationale behind each approach, provide detailed guidelines describing how and when to implement each of the treatments, and summarize outcome research supporting these methods. We include an appendix on CD that incorporates many assessment instruments as well as detailed outlines of treatment protocols to help clinicians understand important features and nuances that can lead to successful outcomes for many patients. This volume has five primary objectives: 1) Provide the reader with a thorough understanding of an integrated psychobiological model that emphasizes the crucial role of learning, memory processes, cognitive processes, and contextual factors as the basis for understanding people with chronic pain. 2) Present a rationale for our belief that the “pain-patient uniformity myth” is wrong. That is, not all people with the same medical diagnosis will benefit from the identical treatment. We believe that matching both

physical and psychological interventions to specific patient characteristics will enhance successful treatment outcome. 3) Provide the reader with a specific rationale indicating how treatment decisions should follow from a comprehensive assessment. 4) Demonstrate the synergy between research and clinical practice. 5) Provide the reader with sufficient detail regarding our comprehensive, multiaxial approach to assessment and treatment so that it can be integrated into clinical practice. We include extensive details on assessment and treatment methods, because we believe not only that better outcomes can be achieved but that more meaningful research can be conducted when we focus on specific treatments rather tan relying on vague descriptions and treatment titles such as “operant (behavioral) therapy,” ”cognitive-behavioral therapy,” “extinction training,” ”biofeedback,” and “multidisciplinary/interdisciplinary treatment,” all of which have idiosyncratic meanings and treatment elements. We include our e-mail addresses below and welcome readers’ comments. We hope that readers will let us know how well we have succeeded in accomplishing our objectives.

the person experiencing pain and his or her significant other. (We use the phrase “significant other” throughout this text to refer to a spouse, partner, family member, friend, coworker, or employer. Moreover, “significant others” also include the health care providers with whom the person with pain is in frequent contact.) Despite significant advances in anatomy, neurophysiology, biochemistry, and medicine, pain—especially pain that has persisted beyond the expected period of healing, which is not the result of a progressive disease, or for which there is no identifiable physical pathology—has remained an enigma for clinicians and scientists, as well as for pain sufferers. These pain syndromes, including many chronic and recurrent conditions, have proven particularly recalcitrant to even the most advanced medical, surgical, and pharmacological methods of treatment [25]. In this chapter, we will review the magnitude of the problem of pain, introduce a number of key definitions, and describe the classification of pain syndromes. This foundation is essential for clinicians who want to appreciate the current state of knowledge, understand the basis for assessment and treatment approaches, and communicate effectively with patients, patient’s significant others, other health care providers, and third-party payers about the nature and scope of pain problems, treatment planning, interventions, rehabilitation, and disability.
Foundations of Current Understanding of Pain and Pain Management Pain only became a focus of systematic research and clinical interest within the past 50 years. Prior to the 1960s, pain was relegated primarily to the domain of sensory physiology. Clinical medicine tended to view pain as an epiphenomenon of disease or injury—a response, and therefore of secondary importance. The emphasis was on eliminating the cause of the pain and finding a cure. The assumption was that once the physical cause of the pain was eliminated, pain would subside and no longer represent a significant problem. Thus, pain was not viewed as something worthy of consideration or treatment in its own right; it was only important because it provided information about physical pathology. Otherwise, pain was just a nuisance.
The Psychology of Pain
61
The Operant Conditioning Model of Chronic Pain As noted in Chapter 1, the operant conditioning formulation proposed by Fordyce [49] has substantially contributed to our understanding of chronic pain and has had a significant impact on treatment and rehabilitation. In Chapter 1, we mentioned that the operant model distinguishes between the private pain experience and observable and quantifiable pain behaviors, which are overt communications of pain, distress, and suffering such as moaning, grimacing, or taking medication. It is these behaviors, rather than pain itself, that are assumed to be amenable to behavioral assessment and treatment. The operant conditioning model proposes that acute pain behaviors may come under the control of (be maintained by) external contingencies of reinforcement and thus develop into a chronic pain problem. Pain behaviors may be positively reinforced, for example, by attention from a spouse or from health care providers [128]. Pain behaviors may also be maintained by the termination of unpleasant states, such as a reduction in pain level by analgesic medication or inactivity or the avoidance of undesirable activities such as work or unwanted sexual activity (negative reinforcement). Also, well behaviors (functional activities including working, home-making activities, and self-care) may not be sufficiently reinforcing, and so the more rewarding pain behaviors may be maintained (see Fig. 6).

pain memories on all levels of the nervous system that may, over time, maintain pain even in the absence of peripheral nociceptive input. We propose that in chronic pain, the extinction rather than the acquisition of these learning processes may be especially disturbed. We have summarized the main factors that we believe contribute to the development and maintenance of chronic pain in Fig. 1. We will describe these factors and their potential interactions in more detail in the following sections. It is important, however, to acknowledge that although we have isolated these four components to simplify discussion, they all interact and are not mutually exclusive, nor intended to connote a linear sequence.

Evaluation of the Patient with Chronic Pain
163
The Pain Assessment Interview The clinical interview is an integral part of the assessment of every person with persistent pain. The interview serves to establish a positive, therapeutic relationship, to determine the treatment motivation of the patient, and to obtain a comprehensive history of the pain problem. In addition, the interview will focus on the identification of psychosocial aspects that may cause or maintain the pain, on the history of previous treatments, and on the patient’s attitudes toward the pain (for preparation for referral for a psychological evaluation, see Table IV). Thus, the interview is an important part of the behavioral analysis. When conducting an interview with chronic pain patients, the health care professional should focus not simply on factual information but on specific thoughts and feelings of the patient and his or her significant others (spouse or partner, family, or friends). The professional should observe specific behaviors by the patient as well as the interaction between the patient and significant others. During an interview, it is important to adopt the patient’s perspective. Patients’ and significant others’ beliefs about the cause of symptoms, their trajectory, and beneficial treatments will have important influences on emotional adjustment and compliance with therapeutic interventions. A habitual pattern of maladaptive thoughts may contribute to a sense of hopelessness, dysphoria, and unwillingness to engage in activity. The interviewer should determine both the patient’s and significant others’ expectancies and goals for treatment and address misconceptions or expectations of outcomes that are excessively optimistic and are destined to cause distress when these expectations are not realized. Attention should focus on the patient’s reports of specific thoughts, behaviors, emotions, and physiological responses that precede, accompany, and follow pain episodes or exacerbations, as well as on the environmental conditions and consequences associated with cognitive, emotional, and behavioral responses in these situations. During the interview, the health care provider should attend to the temporal association of these cognitive, affective, and behavioral events and consider their specificity versus generality across situations, as well as the frequency of their occurrence. These details will help to establish salient features of the target situations, including the controlling variables. The interviewer should seek

their homework plan—perhaps they are too tired, the environment is not conducive, they have a high level of pain, they are having interpersonal conflicts, or they may simply forget. We help patients to proactively problem-solve as to what they would do when these types of impediments arise. It is useful to involve the patient as much as possible in developing the homework plan. It is essential to review homework with the patient at the beginning of the next therapeutic session. Appendix 16 includes an illustration of how to discuss and plan homework. Table I provides a sample homework sheet for relaxation exercises that provides a way to keep detailed records of the exercises and the problems patients may have encountered, along with the effects of these problems. Notice that the therapist encourages the patient to suggest the best times to practice and to plan how to deal with any problems that might arise. Charts are helpful because they serve as a reminder to practice. Information about feelings of relaxation before and after practice sessions can be a helpful reinforcement for the patient to keep practicing. Charts

An introduction to operant theory should be part of the treatment program (an abbreviated version should be provided during the overview of treatment before the patient agrees to participate in operant group treatment). To reiterate the previous brief overview, the introduction includes the following components: • • • •
The relationship between bodily processes and learning; The automaticity or unconscious nature of learning; The fact that conscious unlearning or relearning is possible; The concept that chronic pain is a behavior and can be learned and unlearned.
The treatment goals—reduction of excessive disability, improvement of everyday functioning, and better handling of any pain that may persist—need to be emphasized. Appendix 27 gives a sample introduction to operant thinking and operant treatment goals.
Goals and Techniques of Operant Treatment Reducing Pain Behaviors and Enhancing Well Behaviors An important goal of operant treatment is that patients (and therapists) learn to identify pain behaviors and well behaviors. Several exercises involve the identification of pain and well behaviors in the group setting. The therapist explains the concept of pain behaviors as “all behaviors that tell
Introduction to the Cognitive-Behavioral Approach
425
The overriding message of the CBT approach, one that begins with the initial contact and is woven throughout the fabric of treatment, is that people are not helpless in dealing with their pain, nor do they need to view pain as an all-encompassing determinant of their lives. Rather, a variety of resources are available for confronting pain, and pain will come to be viewed by patients in a more differentiated manner. CBT encourages patients to maintain a problem-solving orientation and to develop a sense of resourcefulness, instead of the feelings of helplessness and withdrawal that create a life revolving around bed rest, physician visits, and trips to the pharmacy.
Phases of Cognitive-Behavioral Therapy for Pain Phase 1: Assessment The first two phases of CBT, assessment and reconceptualization, are highly interdependent. The assessment phase serves several distinct functions, as outlined in Table VI. Assessment information is obtained by interviewing patients and significant others, as well as by using standardized Table VI Functions of the assessment phase Establish the extent of physical impairment. Identify levels and areas of psychological distress. Collaboratively establish behavioral goals covering areas such as activity level, utilization of the health care system, patterns of medication use, and responses of significant others. Provide detailed information about the patient’s perceptions of his or her medical condition, opinions about previous treatments, and expectations of the current treatment. Analyze the patient’s occupational history and goals regarding work. Examine the important role of significant others in the maintenance and exacerbation of maladaptive behaviors and determine how these individuals can be positive resources for the process of change. Begin the reconceptualization process by helping patients and significant others to become aware of the situational variability of the pain and the psychological, behavioral, and social factors that influence the nature and degree of pain.
Applying the Cognitive-Behavioral Approach
441
P: Not really. T: Good—oh, but what happens if it rains on Tuesday, the day you planned to begin? P: Hmm, I didn’t think of that… I guess I would wait until Wednesday. The day doesn’t really matter. T: Right—you can set a schedule for yourself, but you can modify it if something comes up that gets in the way. The important thing is to stick to a plan. The details can be flexible—the key is to begin getting active again. Remember, start low and go slow! Work until you meet your goal and not just until you feel some discomfort. Don’t do to much or too little at the beginning. In the interchange described above, we attempted to involve the patient by trying to match his interest with increased activities. We tried to make the goals specific and measurable. We asked the patient to keep a record of his activities so that we could review his progress at the next session. Finally, we had him acknowledge any concerns, anticipate any potential impediments, and think about how he would flexibly deal with these problems if they should arise. The therapist also expresses the interrelationship and interdependence of behavior and physiological processes. Psychophysiological assessment may be of particular value by clearly demonstrating to the patient how behaviors and feelings can influence physiology, using the patient’s experience as an example. T: It is very clear from your pain activity diaries that you tend to stop doing anything and just lie down when your pain gets really bad. P: Yeah, I guess so … it just hurts so bad that I can’t think of anything else. T: What happens to the pain when you lie down? P: Well, it doesn’t really go away unless I take some medication. T: Right. What happens to your “pain gate” when you lie down and just focus on the pain? P: Huh, I don’t know—maybe it gets opened when I kind of focus on it. T: Yes, and the frequent lying down may over time allow your muscles to become weaker, and then they hurt more and more, and then more activities cause pain, so you do even less. Therefore, a vicious circle is created where pain causes inactivity and inactivity leads to more muscle weakness, more isolation, and consequently more pain. So one
