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.

Psychosocial factors and the pain experience of osteoarthritis patients: new findings and new directions

Purpose of reviewThe present paper reviews recent psychosocial research in the area of osteoarthritis pain. First, the review highlights studies of psychosocial factors that can influence osteoarthritis pain. Next, research testing the efficacy of psychosocial treatments for osteoarthritis pain is summarized. Recent findingsRecent studies suggest that asking osteoarthritis patients to recall pain experiences may not be as accurate as having them keep daily pain records. New studies also support the notion that fatigue and increased weight are linked to higher osteoarthritis pain. Osteoarthritis patients who report higher levels of depression are more prone to report increased osteoarthritis pain. New studies also indicate that social factors such as ethnic background, ability to communicate pain to others, and participation in social activities can influence osteoarthritis pain and disability. Cognitions about pain (i.e. pain catastrophizing, acceptance, self-efficacy for pain) also have been found to relate to pain in patients with osteoarthritis. Recent, randomized controlled studies suggest that psychosocial interventions (i.e. self-management programs, exercise) can decrease osteoarthritis pain and disability. SummarySeveral psychosocial variables have been suggested as influencing osteoarthritis pain and disability. There is evidence that psychosocial interventions may decrease osteoarthritis pain and disability.

Pain coping skills training and lifestyle behavioral weight management in patients with knee osteoarthritis: A randomized controlled study

Summary Combined training in pain and weight management in overweight and obese OA patients resulted in improved pain and other outcomes compared to either training alone. ABSTRACT Overweight and obese patients with osteoarthritis (OA) experience more OA pain and disability than patients who are not overweight. This study examined the long‐term efficacy of a combined pain coping skills training (PCST) and lifestyle behavioral weight management (BWM) intervention in overweight and obese OA patients. Patients (n = 232) were randomized to a 6‐month program of: 1) PCST + BWM; 2) PCST‐only; 3) BWM‐only; or 4) standard care control. Assessments of pain, physical disability (Arthritis Impact Measurement Scales [AIMS] physical disability, stiffness, activity, and gait), psychological disability (AIMS psychological disability, pain catastrophizing, arthritis self‐efficacy, weight self‐efficacy), and body weight were collected at 4 time points (pretreatment, posttreatment, and 6 months and 12 months after the completion of treatment). Patients randomized to PCST + BWM demonstrated significantly better treatment outcomes (average of all 3 posttreatment values) in terms of pain, physical disability, stiffness, activity, weight self‐efficacy, and weight when compared to the other 3 conditions (Ps < 0.05). PCST + BWM also did significantly better than at least one of the other conditions (ie, PCST‐only, BWM‐only, or standard care) in terms of psychological disability, pain catastrophizing, and arthritis self‐efficacy. Interventions teaching overweight and obese OA patients pain coping skills and weight management simultaneously may provide the more comprehensive long‐term benefits.

Pain in its environmental context: implications for designing environments to enhance pain control.

There has recently been heightened recognition that environmental factors can influence pain. Clinicians involved in delivering multidisciplinary pain programs often structure the social environment of their treatment settings to help promote adaptive responses to pain. Recent theories of pain (e.g. Craig, 2003, Melzack, 1999, Fields & Basbaum, 1999) highlight the role that sensory stimuli from the environment can play in influencing the pain experience.

Hope in the Context of Lung Cancer: Relationships of Hope to Symptoms and Psychological Distress

CONTEXT Hope may be important in explaining the variability in how patients adjust to lung cancer. OBJECTIVES The aim of this study was to examine how hope, as conceptualized by Snyder et al., is associated with multiple indices of adjustment to lung cancer. This theoretical model of hope suggests that people with high levels of hope are able to think about the pathways to goals (pathways) and feel confident that they can pursue those pathways to reach their goals (agency). METHODS We hypothesized that higher levels of hope, as measured by Snyder et al.s hope scale, would be related to lower levels of pain and other lung cancer symptoms (i.e., fatigue and cough) and lower psychological distress (i.e., depression). Participants in this study included patients with a diagnosis of lung cancer (n=51). All participants provided demographic and medical information and completed measures of hope, lung cancer symptoms, and psychological distress. RESULTS Data analyses found that hope was inversely associated with major symptoms of cancer (i.e., pain, fatigue, and cough) and psychological distress (i.e., depression), even after accounting for important demographic and medical variables (i.e., age and cancer stage). CONCLUSION The findings of this cross-sectional study highlight the potential importance of hope in understanding adjustment to lung cancer. Future longitudinal research could help reveal how hope and adjustment interact over the course of cancer survivorship.

Self-compassion in patients with persistent musculoskeletal pain: Relationship of self-compassion to adjustment to persistent pain

CONTEXT Self-compassion entails qualities such as kindness and understanding toward oneself in difficult circumstances and may influence adjustment to persistent pain. Self-compassion may be a particularly influential factor in pain adjustment for obese individuals who suffer from persistent pain, as they often experience heightened levels of pain and lower levels of psychological functioning. OBJECTIVES The purpose of the present study was to examine the relationship of self-compassion to pain, psychological functioning, pain coping, and disability among patients who have persistent musculoskeletal pain and who are obese. METHODS Eighty-eight obese patients with persistent pain completed a paper-and-pencil self-report assessment measure before or after their appointment with their anesthesiologist. RESULTS Hierarchical linear regression analyses demonstrated that even after controlling for important demographic variables, self-compassion was a significant predictor of negative affect (β=-0.48, P<0.001), positive affect (β=0.29, P=0.01), pain catastrophizing (β=-0.32, P=0.003), and pain disability (β=-0.24, P<0.05). CONCLUSION The results of this study indicate that self-compassion may be important in explaining the variability in pain adjustment among patients who have persistent musculoskeletal pain and are obese.

Psychosocial interventions for managing pain in older adults: outcomes and clinical implications

Interest in the use of psychosocial interventions to help older adults manage pain is growing. In this article, we review this approach. The first section reviews the conceptual background for psychosocial interventions with a special emphasis on the biopsychosocial model of pain. The second section highlights three psychosocial interventions used with older adults: cognitive behavioural therapy, emotional disclosure, and mind-body interventions (specifically mindfulness-based stress reduction and yoga). The final section of the paper highlights important future directions for work in this area.

Coping with sexual concerns after cancer: the use of flexible coping

IntroductionAlthough cancer treatment commonly has a negative impact on sexual functioning, sexual concerns are still largely undertreated in routine cancer care. The medical model that guides current approaches to sexual care in cancer does not adequately address key patient needs.MethodsIn this paper, we describe a broader approach to understanding and treating sexual concerns in cancer that focuses on the construct of flexibility in behavioral and cognitive coping strategies. We previously presented this model in the context of general medical conditions. We now adapt this model to the context of cancer, focusing on issues related to the benefits of flexible coping, interventions that shift perspectives following cancer, and on coping as a couple.ResultsWe argue that coping flexibly with sexual concerns is likely to lead to improvements in mood and sexual and relationship satisfaction. We present clinical applications of the flexible coping model, including suggestions for assessment and sexual concerns and methods of introducing flexible coping into both the content and process of clinical interactions with patients.DiscussionFinally, we discuss areas for future research, including the development of a validated instrument, the use of electronic methods of assessment, and intervention trials directly addressing flexibility in coping.

Domain Specific Self-Efficacy Mediates the Impact of Pain Catastrophizing on Pain and Disability in Overweight and Obese Osteoarthritis Patients

UNLABELLED This study examined whether self-efficacy mediated the relationship between pain catastrophizing and pain and disability. Participants were 192 individuals diagnosed with osteoarthritis (OA) of the knees who were overweight or obese. Multiple mediator analyses were conducted to simultaneously test self-efficacy for pain control, physical function, and emotional symptoms as mediators while controlling for demographic and medical status variables. Higher pain catastrophizing was associated with lower self-efficacy in all 3 domains (Ps < .05). Self-efficacy for pain control fully mediated the relationship between pain catastrophizing and pain (beta = .08, Sobel test Z = 1.97, P < .05). The relationship between pain catastrophizing and physical disability was fully mediated by self-efficacy for physical function (beta = .06, Sobel test Z = 1.95, P = .05). Self-efficacy for emotional symptoms partially mediated the relationship between pain catastrophizing and psychological disability (beta = .12, Sobel test Z = 2.92, P < .05). These results indicate that higher pain catastrophizing contributed to greater pain and disability via lower domain-specific self-efficacy. Efforts to reduce pain and improve functioning in OA patients should consider addressing pain catastrophizing and domain specific self-efficacy. Pain catastrophizing may be addressed through cognitive therapy techniques and self-efficacy may be enhanced through practice of relevant skills and personal accomplishments. PERSPECTIVE This study found that higher pain catastrophizing contributed to greater pain and disability via domain specific self-efficacy. These results suggest that treatment efforts to reduce pain and improve functioning in OA patients who are overweight or obese should consider addressing both pain catastrophizing and self-efficacy.

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

&NA; 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.
