Self-system therapy for distress associated with persistent low back pain: A randomized clinical trial.

OBJECTIVE: Persistent low back pain (PLBP) is associated with vulnerability to depression. PLBP frequently requires major changes in occupation and lifestyle, which can lead to a sense of failing to attain one's personal goals (self-discrepancy). METHOD: We conducted a clinical trial to examine the efficacy of self-system therapy (SST), a brief structured therapy for depression based on self-discrepancy theory. A total of 101 patients with PLBP and clinically significant depressive symptoms were randomized either to SST, pain education, or standard care. RESULTS: Patients receiving SST showed significantly greater improvement in depressive symptoms. Reduction in self-discrepancy predicted reduction in depressive symptoms only within the SST condition. CONCLUSIONS: Findings support the utility of SST for individuals facing persistent pain and associated depression.

Pain catastrophizing in patients with noncardiac chest pain: relationships with pain, anxiety, and disability.

OBJECTIVE: To examine the contributions of chest pain, anxiety, and pain catastrophizing to disability in 97 patients with noncardiac chest pain (NCCP) and to test whether chest pain and anxiety were related indirectly to greater disability via pain catastrophizing. METHODS: Participants completed daily diaries measuring chest pain for 7 days before completing measures of pain catastrophizing, trait anxiety, and disability. Linear path model analyses examined the contributions of chest pain, trait anxiety, and catastrophizing to physical disability, psychosocial disability, and disability in work, home, and recreational activities. RESULTS: Path models accounted for a significant amount of the variability in disability scales (R(2) = 0.35 to 0.52). Chest pain and anxiety accounted for 46% of the variance in pain catastrophizing. Both chest pain (beta = 0.18, Sobel test Z = 2.58, p < .01) and trait anxiety (beta = 0.14, Sobel test Z = 2.11, p < .05) demonstrated significant indirect relationships with physical disability via pain catastrophizing. Chest pain demonstrated a significant indirect relationship with psychosocial disability via pain catastrophizing (beta = 0.12, Sobel test Z = 1.96, p = .05). After controlling for the effects of chest pain and anxiety, pain catastrophizing was no longer related to disability in work, home, and recreational activities. CONCLUSIONS: Chest pain and anxiety were directly related to greater disability and indirectly related to physical and psychosocial disability via pain catastrophizing. Efforts to improve functioning in patients with NCCP should consider addressing pain catastrophizing.

Partner-guided cancer pain management at the end of life: a preliminary study.

This preliminary study tested the efficacy of a partner-guided cancer pain management protocol for patients who are at the end of life. Seventy-eight advanced cancer patients meeting criteria for hospice eligibility and their partners were randomly assigned to a partner-guided pain management training intervention, or usual care control condition. The partner-guided pain management training protocol was a three-session intervention conducted in patients' homes that integrated educational information about cancer pain with systematic training of patients and partners in cognitive and behavioral pain coping skills. Data analyses revealed that the partner-guided pain management protocol produced significant increases in partners' ratings of their self-efficacy for helping the patient control pain and self-efficacy for controlling other symptoms. Partners receiving this training also showed a trend to report improvements in their levels of caregiver strain. Overall, the results of this preliminary study suggest that a partner-guided pain management protocol may have benefits in the context of cancer pain at the end of life. Given the significance of pain at the end of life, future research in this area appears warranted.

Self-discrepancy in chronic low back pain: relation to pain, depression, and psychological distress.

Self-discrepancies occur when patients' evaluations of their actual self differ from their views of who they ideally would like to be (ideal self) or feel they ought to be (ought self), or from patients' perceptions of how significant others wish they could be (ideal-other self) or ought to be (ought-other self). These self-discrepancies may be related to psychological functioning and adjustment to pain. This study sought to: 1) determine the reliability of self-discrepancy assessments in patients; 2) determine whether each of the four types of self-discrepancies (actual self vs. ideal self, actual self vs. ought self, actual self vs. ideal-other self and actual self vs. ought-other self) measure a distinct type of self-discrepancy; and, 3) examine the relationship of self-discrepancies to pain intensity, depression, and psychological distress in 93 chronic low back pain patients. A semi-structured questionnaire assessed self-discrepancies. Standardized measures were used to assess pain intensity, depression, and psychological distress. Results showed that self-discrepancies can be reliably assessed in patients with persistent pain. Furthermore, data analyses showed that patients who had large ought-other self-discrepancies reported more severe pain and higher levels of psychological distress. Patients who had large ideal self-discrepancies reported higher levels of depression and psychological distress. Taken together, these findings suggest that self-discrepancy can be reliably assessed in patients with persistent pain and demonstrate that self-discrepancies are related in meaningful ways to measures of pain, depression, and psychological distress in chronic low back pain patients.

Patterns of opioid analgesic prescription among patients with osteoarthritis.

This study describes patterns of opioid analgesic prescription during a one-year period among a sample of patients with osteoarthritis (OA). The study sample included 3,061 patients with prior ICD-9 codes indicating a diagnosis of OA who were treated at a federal Veterans Affairs Medical Center. Specific opioid variables included: any opioid prescription, number of specific opioid drugs prescribed, total number of opioid prescriptions, total number of days supply of opioids, and daily opioid doses. We also examined relationships of demographic characteristics to opioid variables. Results revealed that 41% of patients received at least one opioid prescription. Opioids were prescribed significantly less frequently among African-Americans than Caucasians and the number of opioid prescriptions declined with increasing age. The mean annual supply of opioids was 104 days. Days' supply of opioids was also lower for African Americans and older patients. Daily opioid doses were, on average, below recommended daily doses for the treatment of OA. Findings of this study suggest that opioids are frequently prescribed to individuals with OA and that these drugs may be gaining acceptability for the treatment of chronic musculoskeletal pain. Additional research is needed to examine reasons for racial differences in opioid prescribing, as well as the prescription of these medications at fairly low doses.

The effects of written emotional disclosure and coping skills training in rheumatoid arthritis: a randomized clinical trial.

OBJECTIVE: Two psychological interventions for rheumatoid arthritis (RA) are cognitive-behavioral coping skills training (CST) and written emotional disclosure (WED). These approaches have developed independently, and their combination may be more effective than either one alone. Furthermore, most studies of each intervention have methodological limitations, and each needs further testing. METHOD: We randomized 264 adults with RA in a 2 × 2 factorial design to 1 of 2 writing conditions (WED vs. control writing) followed by 1 of 2 training conditions (CST vs. arthritis education control training). Patient-reported pain and functioning, blinded evaluations of disease activity and walking speed, and an inflammatory marker (C-reactive protein) were assessed at baseline and 1-, 4-, and 12-month follow-ups. RESULTS: Completion of each intervention was high (>90% of patients), and attrition was low (10.2% at 12-month follow-up). Hierarchical linear modeling of treatment effects over the follow-up period, and analyses of covariance at each assessment point, revealed no interactions between writing and training; however, both interventions had main effects on outcomes, with small effect sizes. Compared with control training, CST decreased pain and psychological symptoms through 12 months. The effects of WED were mixed: Compared with control writing, WED reduced disease activity and physical disability at 1 month only, but WED had more pain than control writing on 1 of 2 measures at 4 and 12 months. CONCLUSIONS: The combination of WED and CST does not improve outcomes, perhaps because each intervention has unique effects at different time points. CST improves health status in RA and is recommended for patients, whereas WED has limited benefits and needs strengthening or better targeting to appropriate patients.

State anxiety is associated with cardiovascular reactivity in young, healthy african americans.

Although several studies have shown that enhanced cardiovascular reactivity can predict hypertension development in African Americans, these findings have not been consistent among all studies examining reactivity and hypertension susceptibility. This inconsistency may be explained by the influence of anxiety (state and trait) on the blood pressure response to stress. Therefore, this study sought to determine whether anxiety is associated with blood pressure response to cold pressor (CP) and anger recall (AR) stress tests in young healthy African Americans. Modeling using state and trait anxiety revealed that state anxiety predicts systolic (SBP) and diastolic blood pressure DBP response to CP and AR (P ≤ 0.02). Interestingly, state anxiety predicted heart rate changes only to CP (P < 0.01; P = 0.3 for AR). Although trait anxiety was associated with SBP response to AR and not CP, it was not a significant predictor of reactivity in our models. We conclude that anxiety levels may contribute to the variable blood pressure response to acute stressors and, therefore, should be assessed when performing cardiovascular reactivity measures.

Masculinity beliefs predict psychosocial functioning in African American prostate cancer survivors.

Research examining psychosocial functioning in African American prostate cancer survivors has been limited, in spite of documented higher mortality from prostate cancer and worse long-term physical and emotional outcomes from prostate cancer treatment reported by this group of survivors. In addition, the role of masculinity in psychosocial adjustment among prostate cancer survivors is not well understood. In this study, 59 African American prostate cancer survivors completed a questionnaire assessing masculinity beliefs related to self-reliance, emotional control, and dominance, as well as measures of psychosocial functioning (i.e., symptom distress, negative mood, and functional and social well-being). Results of regression analyses indicated that masculinity beliefs predicted negative mood, functional well-being, and social well-being, controlling for age, income, and medical comorbidities. The findings reported here, although preliminary, suggest that masculinity beliefs could be important therapeutic targets for improving the efficacy of cognitive-behavioral interventions for men adjusting to prostate cancer survivorship.

Effects of coping skills training and sertraline in patients with non-cardiac chest pain: a randomized controlled study.

Non-cardiac chest pain (NCCP) is a common and distressing condition. Prior studies suggest that psychotropic medication or pain coping skills training (CST) may benefit NCCP patients. To our knowledge, no clinical trials have examined the separate and combined effects of CST and psychotropic medication in the management of NCCP. This randomized clinical trial examined the separate and combined effects of CST and antidepressant medication (sertraline) in participants with non-cardiac chest pain. A sample of individuals diagnosed with NCCP was randomly assigned to one of four treatments: (1) CST plus sertraline (CST+sertraline), (2) CST plus placebo (CST+placebo), (3) sertraline alone, or (4) placebo alone. Assessments of pain intensity, pain unpleasantness, anxiety, pain catastrophizing, depression, and physical disability were collected prior to treatment, and at 10- and 34-weeks following randomization. Data analyses revealed that CST and sertraline either alone or in combination significantly reduced pain intensity and pain unpleasantness. The combination of CST plus sertraline may have the greatest promise in that, when compared to placebo alone, it not only significantly reduced pain but also pain catastrophizing and anxiety. Overall, these findings support the importance of further research on the effects of CST and sertraline for non-cardiac chest pain.

Pain catastrophizing and pain-related fear in osteoarthritis patients: relationships to pain and disability.

This study examined the degree to which pain catastrophizing and pain-related fear explain pain, psychological disability, physical disability, and walking speed in patients with osteoarthritis (OA) of the knee. Participants in this study were 106 individuals diagnosed as having OA of at least one knee, who reported knee pain persisting for six months or longer. Results suggest that pain catastrophizing explained a significant proportion (all Ps < or = 0.05) of variance in measures of pain (partial r(2) [pr(2)] = 0.10), psychological disability (pr(2) = 0.20), physical disability (pr(2) = 0.11), and gait velocity at normal (pr(2) = 0.04), fast (pr(2) = 0.04), and intermediate speeds (pr(2) = 0.04). Pain-related fear explained a significant proportion of the variance in measures of psychological disability (pr(2) = 0.07) and walking at a fast speed (pr(2) = 0.05). Pain cognitions, particularly pain catastrophizing, appear to be important variables in understanding pain, disability, and walking at normal, fast, and intermediate speeds in knee OA patients. Clinicians interested in understanding variations in pain and disability in this population may benefit by expanding the focus of their inquiries beyond traditional medical and demographic variables to include an assessment of pain catastrophizing and pain-related fear.

Pain behavior in rheumatoid arthritis patients: identification of pain behavior subgroups.

This study used Ward's minimum variance hierarchical cluster analysis to identify homogeneous subgroups of rheumatoid arthritis patients suffering from chronic pain who exhibited similar pain behavior patterns during a videotaped behavior sample. Ninety-two rheumatoid arthritis patients were divided into two samples. Six motor pain behaviors were examined: guarding, bracing, active rubbing, rigidity, grimacing, and sighing. The cluster analysis procedure identified four similar subgroups in Samples 1 and 2. The first subgroup exhibited low levels of all pain behaviors. The second subgroup exhibited a high level of guarding and low levels of other pain behaviors. The third subgroup exhibited high levels of guarding and rigidity and low levels of other pain behaviors. The fourth subgroup exhibited high levels of guarding and active rubbing and low levels of other pain behaviors. Sample 1 contained a fifth subgroup that exhibited a high level of active rubbing and low levels of other pain measures. The results of this study suggest that there are homogeneous subgroups within rheumatoid arthritis patient populations who differ in the motor pain behaviors they exhibit.

A randomized, controlled trial of emotional disclosure in rheumatoid arthritis: can clinician assistance enhance the effects?

Emotional disclosure by writing or talking about stressful life experiences improves health status in non-clinical populations, but its success in clinical populations, particularly rheumatoid arthritis (RA), has been mixed. In this randomized, controlled trial, we attempted to increase the efficacy of emotional disclosure by having a trained clinician help patients emotionally disclose and process stressful experiences. We randomized 98 adults with RA to one of four conditions: (a) private verbal emotional disclosure; (b) clinician-assisted verbal emotional disclosure; (c) arthritis information control (all of which engaged in four, 30-min laboratory sessions); or (d) no-treatment, standard care only control group. Outcome measures (pain, disability, affect, stress) were assessed at baseline, 2 months following treatment (2-month follow-up), and at 5-month, and 15-month follow-ups. A manipulation check demonstrated that, as expected, both types of emotional disclosure led to immediate (post-session) increases in negative affect compared with arthritis information. Outcome analyses at all three follow-ups revealed no clear pattern of effects for either clinician-assisted or private emotional disclosure compared with the two control groups. There were some benefits in terms of a reduction in pain behavior with private disclosure vs. clinician-assisted disclosure at the 2-month follow-up, but no other significant between group differences. We conclude that verbal emotional disclosure about stressful experiences, whether conducted privately or assisted by a clinician, has little or no benefit for people with RA.

Cognitive behavioral approaches to the treatment of pain.

How can cognitive-behavioral therapy benefit patients with persistent pain? The purpose of this review is to provide an overview of cognitive-behavioral treatment approaches to persistent pain. The review is divided into four sections. In the first section, we describe the conceptual back ground for cognitive-behavioral approaches to pain. In the second section, we describe the basic elements of a typical cognitive-behavioral treatment protocol used in pain management. In the third section, we address questions that health care professionals frequently ask about cognitive - behavioral treatment. In the fourth section, we discuss new clinical applications of cognitive-behavioral treatment.
