Pain Management: Cognitive Therapy for Chronic Pain and Fibromyalgia
Group therapy approaches have emerged as a common modality for administering cognitive-behavioral treatments (CBT) for chronic pain. Controlled research has established its efficacy for patients who have a variety of chronic pain problems, including low back pain, facial pain, arthritis (Keefe, Beaupre, & Gil, 2002), and headache (James, Thorn, &Williams, 1993). Surprisingly, there are few studies that have directly compared the efficacy of group versus individual treatments for chronic pain. In the few available comparison studies, there is a consistent lack of difference in treatment outcome between individually administered and group-administered CBT for pain (Frettloh & Kroner- Herwig, 1999; Johnson & Thorn, 1989; Spence, 1989, 1991; Turner-Stokes et al., 2003). Considering practitioner time and patient expense, group treatment is more cost effective than individual therapy—a distinct practical advantage that may be attractive to the busy practitioner as well as to the individual client.
In this article, we present the rationale for group CBT, illustrating with an example of group therapy focusing on the cognitive components of CBT for chronic pain. A cognitive model of pain is used as the framework for the therapy.
As is common to all psychotherapies, CBT for chronic pain requires knowledge regarding the principles of psychotherapy and knowledge regarding personality and psychopathology. Many CBT approaches are manualized, to facilitate administration of the content of the material, but manuals do not often provide information on process such as understanding the client’s nonverbal as well as verbal behaviors, the dynamic nature of the relationship between the client and the therapist, and the timing of the methods based on moment-by-moment developments within the session.
Group therapy for chronic pain has the important added dimension of group process— the interactions among the group members. The effective utilization of the group process can enhance treatment effectiveness and patient satisfaction in cognitive-behavioral treatments for chronic pain. For example, group interactions are useful for modeling appropriate response to a patient who is exhibiting pain behaviors and associated negative affect. Group treatment also serves an instructional purpose by providing the clinician with multiple related examples to choose among for discussion, thus increasing the likelihood that patients will understand the point and implement it in their lives. Individuals struggling with chronic pain often feel isolated and misunderstood; thus, group formats fulfill a supportive function by allowing disclosure of thoughts and feelings to others who have shared similar circumstances, lending a greater sense of legitimacy to the client. At the same time, when a skillful practitioner uses the group process to move clients beyond mutual empathy and toward regaining of function, a crucial component of the psychosocial treatment for chronic pain is served.
Group size and composition are also important patient characteristic considerations. Ideally, a group would comprise between five to seven patients; we favor limiting the size to five because it is sufficient to facilitate interaction among group members while providing enough time for each patient to be heard. With the possible exception of inpatient settings for injured workers or Veterans Administration groups, most CBT groups have more women than men because women have more chronic pain problems, seek pain treatment more frequently than men, and may be more receptive to group therapy because of a tendency to cope via communal support processes (Lyons, Mikelson, Sullivan, & Coyne, 1998; Unruh, 1996).
Although differences in patient age, ethnicity, and cultural background might cause group members to feel less connected with one another, chronic pain seems to be a unifying factor, making other potentially divisive issues less important. For example, we led a recent headache management group composed of four women, three of whom were African American (one 78-year-old who had an eighth-grade education, one 55-year-old social worker, and one 30-year-old elementary school teacher), and one of whom was a White 18-year-old university student. Our supposition was that the youngest group member would drop out prematurely because of the differences in group characteristics, but all group members completed treatment and reported value in the group interactions as part of learning to cope with pain. In reality, constraints imposed in creating a group of individuals who are willing to engage in CBT and who can receive treatment at the same time necessitate great flexibility in terms of creating the "ideal" group mix. Realistically, clients ready for group treatment do not have discrete pain disorders, in the same age cohort, with similar cultural backgrounds and socioeconomic levels. Unless the client is likely to interfere with group process or is unable to keep up with the group, we err on the side of including the person even if we have questions about potential optimal utilization
Targeted Cognitive Intervention for Chronic Pain
The structural foundation of CT for chronic pain is an adaptation of Lazarus and Folkman’s (1984) transactional model of stress. According to the stress-appraisal-coping model of pain patients’ cognitions predict their adjustment to chronic pain through their appraisal of the pain and related stressors, their beliefs about their ability to exert control over pain, and their choice of coping options (Thorn, 2004). A number of important treatment principles come into play in treating chronic pain patients with a CT approach. These principles are presented in Table 1, which summarizes the cognitive model of pain. The research foundation for this program also suggests that cognitive variables are a critical component in successful CBT for chronic pain (see Thorn, 2004, for a review of the relevant literature). In particular, negative pain-related cognitions, particularly catastrophizing, are robust predictors of pain, disability, and adaptation to chronic painful conditions, over and above other factors, such as disease, pain intensity, depression, anxiety, fear of pain, and neuroticism (Sullivan et al., 2001).
