The Need

Patients with chronic or terminal illnesses often experience psychosocial problems that can exacerbate their medical condition, including alienation, anxiety, and depression. Women diagnosed with breast cancer, in particular, often struggle with the stigma associated with cancer, issues regarding body image, fear associated with death, and the stress the disease places on interpersonal relationships. The resulting psychological stress can be considerable. It is estimated that 22 to 50% of patients with breast cancer meet criteria for a psychiatric diagnosis of depression, 3 to 19% meet criteria for posttraumatic stress disorder, and 33% meet criteria for acute stress disorder. Although a full posttraumatic stress syndrome might afflict only a minority of breast cancer patients, most investigators have found that clinically significant symptoms are relatively common. As many as 80% of breast cancer patients report significant distress during initial treatment. Since adjustment to metastatic disease is often more difficult than adjustment to the initial diagnosis, the need to find effective treatments for trauma symptoms in metastatic patients is all the more pressing.

Several decades of research provide evidence that many of the psychosocial problems that chronically ill patients experience respond to psychotherapeutic intervention. For women with breast cancer, there is evidence indicating the effectiveness of group interventions, with positive effects on psychosocial adjustment, physical status, mood, quality of life, and survivorship.

Most randomized group intervention studies have involved brief interventions and have included a focus on education, coping strategies, and emotional support. Some have also included stress management or behavioral training such as hypnosis or progressive relaxation. Most interventions were structured, with a predetermined schedule of topics to be addressed. The supportive-expressive method used in the present study differs in being relatively more extensive and intensive.

The Program

Description

Supportive-expressive group psychotherapy was developed to help patients with breast cancer face and adjust to their existential concerns, express and manage disease-related emotions, increase social support, enhance relationships with family and physicians, and improve symptom control. The supportive-expressive therapy model involves the creation of a supportive environment in which participants are encouraged to confront their problems, strengthen their relationships, and find enhanced meaning in their lives. A major purpose of the therapy sessions is to create a close-knit group that can serve to counter feelings of isolation and enhance social support.

The intervention consists of weekly 90-minute unstructured therapy sessions involving 3-15 participants, led by two therapists (e.g., psychiatrists, psychologists, social workers) who are trained to facilitate discussion in an emotionally expressive rather than didactic format and who are self-trained in the delivery of the intervention. For breast cancer groups, it is helpful if at least one therapist is female. The following themes are discussed: (1) fears of dying and death, including dealing with the deaths of group members; (2) reordering life priorities; (3) improving support from and communication with family and friends; (4) integrating a changed self-image and body image; and (5) improving communication with physicians. Each session ends with a self-hypnosis exercise to help patients manage stress and deal with pain. Patients are encouraged to use this exercise at home.

Required Resources

Required resources for this intervention include:

-- Supportive-Expressive Group Therapy: A Treatment Manual of Psychosocial Intervention for Women with Recurrent Breast Cancer; provides background and guidance.

About the Study

Women with confirmed metastatic or locally recurrent breast cancer were randomized to intervention or control conditions. Women in both conditions were offered a self-directed education intervention, including 30 books, 15 pamphlets, 5 videotapes, and 7 audiotapes that they could select from and take home on loan, as well as a 1-year membership to a consumer health library in their community. Women in the intervention condition also received weekly 90-minute sessions of supportive-expressive group therapy. 

Participants included 102 women who completed the baseline assessment and at least one other follow-up assessment during the 12-month study period. They ranged in age from 33 to 80, with a mean age of 54.0 (SD=10.7) for the control group and 52.9 (SD=10.7) for the treatment group. The majority of the participants were White (86.3%), with 7.8% Asian, 1.0% Black, 1.0% Hispanic, 2.0% American Indian, and 2.0% Other. 

Data were collected at baseline, every 4 months during the first year, and every 6 months thereafter. Traumatic stress symptoms were measured by the Impact of Event Scale (IES), a 15-item measure to assess symptoms of intrusion and avoidance that can occur in response to a potentially traumatic event. Participants were asked to rate on a 4-point Likert-type scale ranging from "not at all" to "often" the frequency of experiencing intrusive and avoidant symptoms during the past 7 days in response to having cancer. The two subscales were combined to give an IES total score. Total mood disturbance was measured with the Profile of Mood States (POMS), where participants rated the extent to which 65 mood-descriptive adjectives described how they felt during the past week. Ratings were based on a 5-point Likert-type scale ranging from "not at all" to "extremely." A total mood disturbance score was calculated based on each of the six subscales: anxiety, depression, hostility, confusion, vigor, and fatigue. Participant survival or death was determined for all participants by research staff communication with participants, family members, and/or physicians, or by consulting the Social Security Death Index. All reported deaths were confirmed by death certificate. Finally, pain level was measured by the Pain Rating Scale, which measures self-reported pain levels, using single Likert-type items. The scale assessed "pain in this moment", from 1 (not noticeable) to 10 (excruciating-worst ever) and "suffering in this moment", from 1 (easily bearable) to 10 (agonizing-unbearable). Pain in this moment and suffering in this moment were highly correlated and also averaged for use in the analyses.

Key Findings

Effects on Trauma Symptoms

  • Women in the treatment condition showed a statistically significant reduction in trauma symptoms compared with the control group (p=.03). 

Graph of Study Results

Effects on Total Mood Disturbance

  • When final follow-up assessments occurring within 1 year of death were excluded, women in the treatment condition showed statistically significant improvements in total mood disturbance compared with those in the control condition (p=.02). 

Graph of Study Results

 
Effects on Survival Time

  • There was no overall effect on survival time, but there was a significant interaction with estrogen receptor status, such that among the estrogen-receptor-negative participants, those randomized to treatment survived longer (median = 29.8 months) than estrogen-receptor-negative controls (median = 9.3 months; p=.002).

Effects on Pain Level

  • Women who received group therapy plus education showed a significantly smaller increase in the intensity of current pain and suffering compared to women who received the educational intervention alone (p=.034).
