Changes after multidisciplinary pain treatment in patient pain beliefs and coping are associated with concurrent changes in patient functioning

Predictors of treatment outcome in cognitive behavioural therapy for chronic pain: a systematic review

PURPOSE

The aim of this systematic review was to synthesise the research identifying possible influences on CBT outcomes in chronic pain. Variations in the effectiveness of psychological therapies, such as CBT, in chronic pain have led to research investigating predictors of improved treatment outcomes.

MATERIALS AND METHODS

We identified randomised controlled and cohort studies of CBT for chronic pain, published between 1974 to 2nd August 2023, which identified predictors of CBT outcomes.

RESULTS

Nineteen studies were included in the review. Baseline sociodemographic, physical and emotional factors that influence the outcomes of CBT for chronic pain were identified. The most commonly reported predictors of CBT outcome, with medium to large effect sizes, were anxiety, depression and negative cognitions about pain and coping. Sociodemographic predictors of outcomes demonstrated small effects and lacked replicability.

CONCLUSIONS

There was variability across study designs, CBT delivery and outcomes measures. Further research is needed in chronic pain to identify the predictive factors which influence treatment outcomes, and consistency across study designs and outcome variables is needed to reduce heterogeneity.

From sceptic to believer: Acceptability of cognitive muscular therapyTM , a new intervention for knee osteoarthritis

BACKGROUND

Cognitive Muscular TherapyTM (CMT) is an integrated behavioural intervention developed for knee osteoarthritis. CMT teaches patients to reconceptualise the condition, integrates muscle biofeedback and aims to reduce muscle overactivity, both in response to pain and during daily activities. This nested qualitative study explored patient and physiotherapist perspectives and experiences of CMT.

METHODS

Five physiotherapists were trained to follow a well-defined protocol and then delivered CMT to at least two patients with knee osteoarthritis. Each patient received seven individual clinical sessions and was provided with access to online learning materials incorporating animated videos. Semi-structured interviews took place after delivery/completion of the intervention and data were analysed at the patient and physiotherapist level.

RESULTS

Five physiotherapists and five patients were interviewed. All described a process of changing beliefs throughout their engagement with CMT. A framework with three phases was developed to organise the data according to how osteoarthritis was conceptualised and how this changed throughout their interactions with CMT. Firstly, was an identification of pain beliefs to be challenged and recognition of how current beliefs can misalign with daily experiences. Secondly was a process of challenging and changing beliefs, validated through new experiences. Finally, there was an embedding of changed beliefs into self-management to continue with activities.

CONCLUSION

This study identified a range of psychological changes which occur during exposure to CMT. These changes enabled patients to reconceptualise their condition, develop a new understanding of their body, understand psychological processes, and make sense of their knee pain.

Effectiveness of cognitive behavioral therapy for patients after total knee arthroplasty: a systematic review and meta-analysis

Total knee arthroplasty (TKA) is considered a common surgical option in patients with end-stage osteoarthritis of the knee. This systematic review and meta-analysis aimed to determine the effectiveness of cognitive behavioral therapy (CBT) for patients after TKA. PubMed, EMBASE, the Cochrane Library, Web of Science and CINAHL were searched for randomized controlled trials (RCTs) from inception to 20 August 2021. Included studies were evaluated with the Cochrane risk-of-bias tool. Six RCTs were included. Our study results demonstrated that a significant reduction in pain catastrophing was seen in patients receiving CBT at post-intervention (SMD -0.48, 95% CI = -0.72 to -0.23, I2 17.2%, p = 0.00) but not in 3-month or 12-month follow-up. There were no significant differences between CBT and usual-care patients regarding pain intensity or knee function at different time-points. This is the first time that meta-analysis has been conducted to determine the effectiveness of CBT for patients after TKA. It is necessary to conduct longer follow-ups, include larger samples and conduct rigorous RCTs to further explore this issue.

A Qualitative Study of Psychosocial Factors in Patients With Knee Osteoarthritis: Insights Learned From an Asian Population

BACKGROUND

A patient's experience with knee osteoarthritis (OA) is influenced by many psychosocial contributors that can influence the impact of pain. Such factors are known to explain some of the discordance between objective clinical parameters and patient-reported levels of disability and treatment effectiveness. However, few data are available to help clinicians understand the psychosocial factors that apply to the world's many Asian populations. Insights gained from a qualitative study in such a population may support targeted interventions.

QUESTIONS/PURPOSES

In this qualitative study involving a group of Asian patients with knee OA in Singapore, we asked: (1) What psychologic factors contribute to patients' experiences, rehabilitation, and recovery? (2) What social factors contribute to patients' experiences, rehabilitation, and recovery?

METHODS

Semistructured interviews eliciting broad patient experiences of managing knee OA were conducted in an urban, referral-based tertiary hospital in central Singapore. Patients were recruited if they met either of the following criteria: Kellgren-Lawrence grade ≥ 3 (minimum of one knee); Knee Injury and Osteoarthritis Outcome Score ≤ 60; or the Pain average (P), interference with Enjoyment of life (E), and interference with General activity (G) (PEG) ≥ 5. All patients had a clinical diagnosis of knee OA, were ambulatory in the community with or without a walking aid, had not undergone partial arthroplasty or TKA, were prescribed nonsurgical treatment, and were conversant in either English or Mandarin. Forty-six patients (30 women and 16 men, mean age 64 years old) were recruited for this study. A thematic analysis with elements of grounded theory and framework analysis was performed using a deductive approach. Psychologic influences specific to patients' behavioral and emotional responses to pain, as well as social factors known to have an impact on the experience of managing knee OA, were identified in the interview transcripts and coded according to established factors from earlier research. An inductive thematic analysis was then applied to the remaining transcripts to identify new themes that emerged from the data. Thematic saturation was attained when study team members agreed data and thematic sufficiency were met in the 46 transcripts. The study team discussed and deemed the 46 transcripts to contain sufficient insights for a reasonably clear understanding of the codes and development of themes to answer the study's research questions.

RESULTS

Six main themes related to psychosocial influences on pain emerged. Psychologic factors were "loss of face" because of knee OA, anticipation and avoidance of pain and suffering, and a vicious cycle of negative emotional experiences. The social factors we identified were social and family support, workplace environment and employment uncertainty, and built environment (patients' ability to navigate manmade structures and facilities).

CONCLUSION

Psychosocial factors have an important impact on patients' physical, psychologic, and social functioning. Although several of our findings have been addressed previously, the phenomenon of loss of face and the wide spectrum of social and family support dynamics found in our Asian patients with knee OA were new findings. With loss of face, patients were concerned about how others would view the change in them, including movement changes because of knee OA. They appeared to associate the use of walking canes with major disability, loss of respect, and being discriminated against by others, motivating patients to "save face" by dissociating themselves from those stigmas, even at the cost of mobility and independence. An interplay of complex cultural processes (perceived social roles and contributions to family, desire to avoid burdening family, help-seeking behavior, and the preference for unsolicited social support) underpinned by the value of collectivism impacted the behaviors and choices patients exhibited.

CLINICAL RELEVANCE

With knowledge about the impact of culturally relevant psychosocial factors on the experience and outcomes of patients with knee OA, clinicians will be able to screen and actively explore these factors more effectively. Especially important themes include pain perception (paying close attention to signs of pain catastrophizing and negative affect), presence of chronic illness shame associated with a diagnosis of knee OA (including the stigma associated with using a walking aid), and level of social support received and contributions of a patient's built environment to kinesiophobia. For patients who are still working, the presence of workplace stressors and management of these stressors should also be explored. Where possible, screening tools that measure psychosocial factors such as pain catastrophizing and emotional distress can also be used as an added layer of screening in busy clinical settings.

Improvements in pain coping predict treatment success among patients with chronic primary pain

OBJECTIVE

Given the increasing incidence and prevalence of chronic pain, effective treatments for chronic pain are needed. This study aimed to investigate the role of cognitive and behavioral pain coping regarding the prediction of treatment outcomes among inpatients with chronic primary pain participating in an interdisciplinary multimodal treatment program.

METHODS

At intake and discharge, 500 patients with chronic primary pain completed questionnaires on pain intensity, pain interference, psychological distress, and pain processing.

RESULTS

Patients' symptoms, cognitive and behavioral pain coping improved significantly after treatment. Similarly, separate cognitive and behaviroal coping skills improved significantly after treatment. Hierarchical linear models revealed no significant associations of pain coping with reductions in pain intensity. Whereas the overall level and improvements in cognitive pain coping predicted reductions in pain interference and psychological distress, the overall level and improvements in behavioral pain coping were associated with reductions in pain interference alone.

DISCUSSION

Since pain coping seems to influence both pain interference and psychological distress, improving cognitive and behavioral pain coping during an interdisciplinary multimodal pain treatment seems to be a key component in the successful treatment of inpatients with chronic primary pain, enabling them to function better physically and mentally despite their chronic pain. Clinically, it might be worth fostering and exercising cognitive restructuring as well as action planning in treatment to reduce both pain interference and psychological distress levels post-treatment. In addition, practicing relaxation techniques might help reduce pain interference post-treatment, whereas making experiences of personal competence might help reduce psychological distress post-treatment.

Moderators and Nonspecific Predictors of Treatment Benefits in a Randomized Trial of Mindfulness-Based Stress Reduction vs Cognitive-Behavioral Therapy vs Usual Care for Chronic Low Back Pain

Both mindfulness-based stress reduction (MBSR) and cognitive-behavioral therapy (CBT) are effective for chronic low back pain (CLBP), but little is known regarding who might benefit more from one than the other. Using data from a randomized trial comparing MBSR, CBT, and usual care (UC) for adults aged 20 to 70 years with CLBP (N = 297), we examined baseline characteristics that moderated treatment effects or were associated with improvement regardless of treatment. Outcomes included 8-week function (modified Roland Disability Questionnaire), pain bothersomeness (0-10 numerical rating scale), and depression (Patient Health Questionnaire-8). There were differences in the effects of CBT versus MBSR on pain based on participant gender (P = .03) and baseline depressive symptoms (P = .01), but the only statistically significant moderator after Bonferroni correction was the nonjudging dimension of mindfulness. Scores on this measure moderated the effects of CBT versus MBSR on both function (P = .001) and pain (P = .04). Pain control beliefs (P <.001) and lower anxiety (P < .001) predicted improvement regardless of treatment. Replication of these findings is needed to guide treatment decision-making for CLBP. TRIAL REGISTRATION: The trial and analysis plan were preregistered in ClinicalTrials.gov (Identifier: NCT01467843). PERSPECTIVE: Although few potential moderators and nonspecific predictors of benefits from CBT or MBSR for CLBP were statistically significant after adjustment for multiple comparisons, these findings suggest potentially fruitful directions for confirmatory research while providing reassurance that patients could reasonably expect to benefit from either treatment.

Effects of Anodal Transcranial Direct Current Stimulation on the Primary Motor Cortex in Women With Fibromyalgia: A Randomized, Triple-Blind Clinical Trial

OBJECTIVES

The aim of this study was to analyze the effects of ten sessions of active transcranial direct current stimulation transcranial direct current stimulation (tDCS) (2 mA) with 13:20:13 stimulation at M1 in women with fibromyalgia (FM). To the best of our knowledge, this is the first article that uses this protocol in patients with FM. The main hypothesis is that the protocol would be effective in decreasing pain and that the results would last for up to 90 days.

MATERIALS AND METHODS

This study was a randomized clinical trial with 35 women with FM divided into two groups, active tDCS group and sham tDCS group. A conventional tDCS device was used to deliver 2 mA for 13 minutes, with a 20-minute break followed by a further 13 minutes of stimulation for ten sessions. The anodal stimulus was in the left primary motor cortex M1 region. The primary outcome was a change in the visual analog scale and the Survey of Pain Attitudes pain score at the end of treatment, after 30 days, and 90 days after the end of treatment. Secondary outcomes included changes in the Fibromyalgia Impact Questionnaire, Hamilton Anxiety Rating Scale, Hamilton Depression Rating Scale, World Health Organization's Quality of Life Questionnaire, and Fatigue Assessment Scale. The Research Ethics Committee of the Centro Universitário da Grande Dourados under registration number Certificado de Apresentação de Apreciação Ética approved this research: 36444920.5.0000.5159. The study was registered in The Brazilian Registry of Clinical Trials with the identifier RBR-8wc8rjq.

RESULTS

The active tDCS group showed improvement in pain after ten sessions (p < 0.001), after 30 days (p < 0.01), and after 90 days (p < 0.001) compared with sham tDCS. In addition, improvement in quality of life (QoL) and fatigue was observed in the active tDCS group.

CONCLUSION

The results of this study suggest that active tDCS with an intensity of 2 mA for ten sessions was effective in decreasing pain and fatigue and improving QoL in patients with FM.

Refining the Implementation of a Hub-and-Spoke Model for TelePain Through Qualitative Inquiry

The hub-and-spoke telehealth model leverages centrally located providers who utilize telehealth technology to bring specialized care to medically underserved areas. This model has the potential to promote equitable access to healthcare. However, few studies address how to facilitate the adoption and implementation of hub-and-spoke telehealth. We examined spoke site providers' experiences with TelePain, a national hub-and-spoke model of interdisciplinary chronic pain care, with a focus on improving future implementation. We conducted semi-structured individual interviews (20-45 min) with 27 VA spoke site providers via teleconferencing between August 2020 and February 2021. Interview transcripts were coded in Atlas.ti 8.0 using deductive (identified a priori and used to build the interview guide) and inductive (emerging) codes. Our analysis identified the following themes stressed by the spoke sites: (1) spoke sites needed to envision how TelePain services would work at their site before deciding to adopt; (2) TelePain implementation needed to fit into local existing care processes; (3) hub sites needed to understand spoke sites' context (e.g., via needs assessment) to tailor the services accordingly, and (4) hub-and-spoke sites needed to establish bidirectional communication. Our findings provide a practical guide to improve future rollout of hub-and-spoke telehealth models. Recommendations focus on the role of the hub site in promoting program adoption by (1) developing a clear and detailed marketing plan and (2) considering how the program can be adapted to fit the local spoke site context. To improve implementation, hub-and-spoke sites must establish ongoing and consistent bidirectional communication; this is particularly critical in the everchanging post-peak pandemic healthcare system. An important next step is the development of recommendations and guidelines for implementing hub-and-spoke telehealth, as well as examining pain outcomes for patients touched by this program.

"FastSchool": A single session of an interprofessional pain management program for chronic pain patients inspired by cognitive behavioral therapy

OBJECTIVES

Multidisciplinary approaches to treating chronic pain have been proven effective. Currently, chronic pain patients face lengthy waitlists in pain medicine departments. To overcome this problem, we developed the "FastSchool" program to educate patients about pain management and treatment. In this study, we evaluated the benefit of a "FastSchool" session on pain and catastrophizing in chronic pain patients.

METHODS

Included patients had chronic non-cancer pain, no more than 2 visits to a pain medicine department. Patients attended a single 3-hour session, conducted by an interprofessional team. Four topics were addressed: chronic pain mechanisms, pharmacological therapies, physical activity, and the management of analgesics. Patients completed questionnaires at baseline and at 3 months post-session to assess pain interference, pain intensity, and catastrophizing.

RESULTS

The study population included 88 patients; 71 completed the follow-up questionnaires. Pain interference (p = 0.002), average pain intensity (p = 0.013), and catastrophizing (p < 0.001) decreased 3 months after FastSchool. At M3, 35 % of patients felt their pain had improved based on the Patient Global Impression of Change.

CONCLUSION

FastSchool, an innovative short-term educational program inspired by cognitive behavioral therapy, showed positive results in reducing pain impact.

PRACTICE IMPLICATIONS

Implementation of FastSchool in pain medicine departments would reduce waitlist times for non-pharmacological treatment.

Chronic pain in adults with osteogenesis imperfecta and its relationship to appraisal, coping, and quality of life: A cross-sectional study

Chronic pain is a common experience in osteogenesis imperfecta (OI). However, there are few studies on this topic, and none of them emerge from psychology as a discipline. The purpose of this work is to describe the frequency of chronic pain and its characteristics in a large sample of adults with OI, as well as its relationship with clinical, sociodemographic, psychological, and quality of life variables. A cross-sectional study was carried out in a sample of 418 adults with OI who answered a battery of online questionnaires. Sociodemographic and clinical variables, pain parameters, participants' appraisal of pain, coping strategies, interference in daily activities, and health-related quality of life were evaluated. A descriptive and correlational analysis was performed. Up to 83% of the sample reported experiencing pain frequently. Both the frequency and intensity of pain were related to the accumulation of fractures over the years (P < .05), but were independent of other variables like the severity of the pathology or the use of bisphosphonates. Higher threat appraisal of pain was associated with an increase in perceived pain intensity and its interference with daily activities, as well as a decrease in physical and mental health (P < .001). Chronic pain frequent condition in adults with OI, regardless of the severity of the pathology. It interferes with their usual activities and has an impact on their quality of life. The way in which participants appraise their pain also have an influence on its intensity and its consequences. Interventions aimed at training strategies for managing appraisals about pain could potentially improve adaptation to chronic pain.

Neurophysiology of hypnosis in chronic pain: A review of recent literature

Chronic pain is a complex phenomenon which includes biological, psychological, and socio-professional factors that undermine patients' everyday life. Currently, only few patients significantly benefit from pharmacological treatments and many have to stop them because of negative side effects. Moreover, no medication or treatment addresses all aspects of chronic pain at once (i.e., sensations, emotions, behaviors, and cognitions), positioning chronic pain as an important public health issue and thus contributing to high health-care costs. Consequently, patients and health-care providers are increasingly turning to complementary non-pharmacological techniques such as hypnosis. Clinical research has demonstrated a decrease of pain perception, pain interference, depression and anxiety, and an increase in global quality of life when patients with chronic pain have benefited from hypnosis learning. Neuroimaging studies offer a possible explanation of these results by focusing on neural processes of pain modulation in chronic pain patients' brain. Studies conducted with chronic pain patients showed a modulation of pain matrix activity during hypnosis with a specific involvement of the anterior cingulate cortex (related to emotional and cognitive processing of pain). Therefore, hypnosis seems to act upon regions underlying emotion and cognition, with an influence on pain perception and emotional regulation. In this review, we propose to carry out a review of the recent literature on hypnosis in chronic pain management. A better understanding of the beneficial effects of hypnosis on chronic pain and its neurophysiology should enable more systematic use of this technique in the management of this complex health problem.

[Noninvasive Treatments for Acute and Chronic Back Pain]

Noninvasive Treatments for Acute and Chronic Back Pain Abstract. The therapy of back pain - especially the medication with opioids - can be challenging for the treating physician. Specific back pain can often be diagnosed by imaging and successfully treated by surgery or medication. In contrast, nonspecific back pain can be worsened by inappropriate imaging, questionable surgical indications and uncontrolled drug use. For the therapy of nonspecific back pain, maintaining daily activity and exercise therapy is central. Opioids are effective drugs for short-term use. However, long-term use often leads to opioid-induced hyperalgesia and hormonal dysfunction with decreased quality of life and libido. Furthermore, opioids can lead to abuse and addiction. After an ineffective treatment with non-opioids, opioids may be given for a limited time period (if possible shorter than four weeks) according to international guidelines.

Pain Control: Normalization of the BPCQ Questionnaire on a Group of Patients Diagnosed with Malignant Cancer

The purpose of this article is to examine the applicability of the Beliefs about Pain Control Questionnaire (BPCQ) among cancer patients and develop norms that allow differentiation of patients with diagnosed cancer in terms of beliefs about pain control. Normalization aims to establish the value of test results in the study population. The study involved 1187 patients diagnosed with cancer in outpatient care Maria Sklodowska-Curie Cancer Center and Institute of Oncology, in Warsaw. The applied tool was the Beliefs about Pain Control Questionnaire developed by S. Skevington. The results are most strongly differentiated in each dimension of pain control by education, income, and professional status. Sten norms were developed to determine the level of beliefs about pain control in low, average, and high categories. The BPCQ assessment applies to cancer patients, and the assessment of the location of pain control in patients will allow for the identification of patients whose standard therapy should be supplemented with psychotherapeutic support.

Refractory Chronic Pain and Obesity: Promising Implications for Multidisciplinary Pain Rehabilitation

OBJECTIVE

Individuals with obesity frequently contend with chronic pain, but few studies address the clinical impact of coordinated pain services on this population. The current study addresses this topic by comparing the effectiveness of a comprehensive pain rehabilitation program for patients with and without obesity.

METHODS

A retrospective analysis of registry data was conducted. Obesity was considered as one of three weight groups, based on the following body mass index cutoffs: normal weight (18.5 to < 25 kg/m2), overweight (25 to < 30 kg/m2), and obese (> 30 kg/m2). These groups were compared on the Pain Severity Ratings (PSR) Scale, the Pain Disability Index (PDI), and the Depression, Anxiety, Stress Scales-Short Form (DASS-SF).

RESULTS

Groups differed on baseline pain disability and depression. Patients with obesity had higher scores on both the PDI (P = .028) and the DASS-SF depression subscale (P = .006). Contrary to the hypothesis, after controlling for baseline score and sex there were no significant differences between weight groups with regards to PSR, PDI, or any DASS-SF subscale at discharge. At 1-year follow-up, individuals who were overweight and obese had significantly more anxiety compared to individuals whose weight was in the normal range.

CONCLUSIONS

Multidisciplinary pain rehabilitation programs appear to be an effective treatment intervention for patients who have concomitant chronic pain and obesity, to a degree comparable to patients who have chronic pain but do not contend with obesity. Implications for program development, clinical interventions, and future research are discussed.

Development and field testing of primary care screening tools for harms of long-term opioid therapy continuation and tapering to discontinuation: a study protocol

INTRODUCTION

Despite calls for screening tools to help providers monitor long-term opioid therapy (LTOT) harms, and identify patients likely to experience harms of discontinuation, such screening tools do not yet exist. Current assessment tools are infeasible to use routinely in primary care and focus mainly on behaviours suggestive of opioid use disorder to the exclusion of other potential harms. This paper describes a study protocol to develop two screening tools that comprise one integrated instrument, Screen to Evaluate and Treat (SET). SET1 will indicate if LTOT may be harmful to continue (yes or no), and SET2 will indicate if tapering to discontinue opioids may be harmful to initiate (yes or no). Patients receiving LTOT who screen positive on the SET tools should receive subsequent additional assessment. SET will give providers methods that are feasible to implement routinely to facilitate more intensive and comprehensive monitoring of patients on LTOT and decision-making about discontinuation.

METHODS AND ANALYSIS

We will develop the screening tools, SET1 and SET2, concurrently. Tool development will be done in stages: (1) comprehensive literature searches to yield an initial item pool for domains covered by each screening tool; (2) qualitative item analyses using interviews, expert review and cognitive interviewing, with subsequent item revision, to yield draft versions of each tool; and (3) field testing of the draft screening tools to assess internal consistency, test-retest reliability and convergent and discriminant validity.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the Institutional Review Boards of Stanford University and the University of California, San Francisco for the VA Palo Alto Health Care System, and the VA San Francisco Healthcare System, respectively. Findings will be disseminated through peer-reviewed manuscripts and presentations at research conferences.

What is pain: Are cognitive and social features core components?

Pain is a universal experience, but it has been challenging to adequately define. The revised definition of pain recently published by the International Association for the Study of Pain addressed important shortcomings of the previous version; however, it remains narrow in its focus on sensory and emotional features of pain, failing to capture the substantial roles of cognitive and social core components of the experience and their importance to advances in pain management. This paper reviews evidence and theoretical models for the significant role social and cognitive factors play in pain experience and we argue that without explicit recognition of these core components in the definition, significant nuances are lost at a cost to understanding and clinical management of pain. A focus on sensory and emotional features perpetuates biomedical interventions and research, whereas recognition of cognitive and social features supports a multidimensional model of pain, advances in interdisciplinary care, and the benefits of cognitive behavioral therapy and self‐management interventions. We also explore the six Key Notes that accompany the new definition of pain, discuss their application to the understanding of pain in childhood, and, in doing so, further explore social and cognitive implications. Considerations are also described for assessment and treatment of pain in pediatric populations.

The Effect of Literacy-Adapted Psychosocial Treatments on Biomedical and Biopsychosocial Pain Conceptualization

This is a secondary data analysis of a subgroup of participants who received the Learning About My Pain (LAMP) intervention (clinicaltrials.gov identifier NCT01967342). We examined the effects of LAMP on pre-to-post changes in biomedical and biopsychosocial pain conceptualization and whether those changes in pain conceptualization were associated with physical and psychological functioning. Participants were randomized into three conditions: Cognitive Behavioral Therapy (CBT), Pain Psychoeducation (EDU), or Usual Medical Care (UC). Results based on 225 participants who completed the Pain Concepts Questionnaire (PCQ) showed a pre-to-post reduction in biomedical pain conceptualization (BM), an increase in biopsychosocial pain conceptualization (BPS), and an increase in BPS/BM ratio for CBT and EDU but not UC. There were no differences between CBT and EDU in post-treatment PCQ scores. Compared to those with lower BM pain beliefs scores at post-treatment, participants endorsing higher BM pain beliefs scores reported greater pain intensity and greater pain interference. Furthermore, higher BM pain beliefs scores at post-treatment and lower BPS/BM ratio were associated with higher levels of pain catastrophizing. Overall, results of this study suggest the need for targeting specific pain beliefs that influence pain-related outcomes. PERSPECTIVE: This article presents the potential benefits of providing literacy-adapted psychosocial treatments to expand pain conceptualization beyond a biomedical-only understanding and toward a biopsychosocial conceptualization of the experience of pain. Furthermore, the association of changes in pain conceptualization and pain-related functioning argues for its potential clinical relevance.

Group Differences Between Countries and Between Languages in Pain-Related Beliefs, Coping, and Catastrophizing in Chronic Pain: A Systematic Review

Objective

To evaluate the extent to which pain-related beliefs, appraisals, coping, and catastrophizing differ between countries, language groups, and country economy.

Design

Systematic review.

Methods

Two independent reviewers searched 15 databases without restriction for date or language of publication. Studies comparing pain beliefs/appraisals, coping, or catastrophizing across two or more countries or language groups in adults with chronic pain (pain for longer than three months) were included. Two independent reviewers extracted data and performed the quality appraisal. Study quality was rated as low, moderate, or high using a 10-item modified STROBE checklist. Effect sizes were reported as small (0.20–0.49), medium (0.50–0.79), or large (≥0.80).

Results

We retrieved 1,365 articles, read 42 potential full texts, and included 10 (four moderate-quality, six low-quality) studies. A total of 6,797 adults with chronic pain (33% with chronic low back pain) were included from 16 countries. Meta-analysis was not performed because of heterogeneity in the studies. A total of 103 effect sizes were computed for individual studies, some of which indicated between-country differences in pain beliefs, coping, and catastrophizing. Of these, the majority of effect sizes for pain beliefs/appraisal (60%; eight large, eight medium, and eight small), for coping (60%; seven large, 11 medium, and 16 small), and for catastrophizing (50%; two medium, one small) evidenced statistically significant between-country differences, although study quality was low to moderate.

Conclusions

In 50% or more of the studies, mean scores in the measures of pain beliefs and appraisals, coping responses, and catastrophizing were significantly different between people from different countries.

Factors associated with exercise adherence to prevent or treat neck and low back pain: A systematic review

BACKGROUND

Much attention has been paid to the evaluation of the efficacy of exercise therapy or increasing physical activity with the aim to prevent or alleviate neck and low back pain. However, exercise adherence is necessary for the effective management of neck and low back pain.

OBJECTIVE

We aimed to systematically review randomized controlled trials and cohort studies to gain insights into the factors associated with adherence to exercise or physical activity programs to prevent or treat neck pain and low back pain.

METHOD

Publications were systematically searched from 1980-December 2019 in several databases. The following key words were used: neck pain or low back pain paired with exercise or physical activity and adherence or compliance. Relevant studies were retrieved and assessed for methodological quality by two independent reviewers. Quality of evidence was assessed and rated according to GRADE guidelines.

RESULTS

Nine randomized controlled trials and eight cohort studies were included in this review. Randomized controlled trials indicated moderate-quality evidence for the association between exercise adherence and self-efficacy. Cohort studies showed moderate-quality evidence for the association between exercise adherence and education level.

CONCLUSIONS

Literature investigating factors associated with exercise adherence to prevent or treat neck and low back pain was heterogeneous. Few factors were found to be associated with exercise adherence. More studies are needed before any firm conclusions can be reached.

Patient-Centered Care in Psoriatic Arthritis-A Perspective on Inflammation, Disease Activity, and Psychosocial Factors

Psoriatic arthritis (PsA) is a seronegative spondyloarthropathy characterized by skin lesions, dactylitis, and enthesitis. Patients with PsA suffer from a variety of psychosocial difficulties and nonspecific symptoms early on in the disease course and continue to experience progressive disease due to delays in diagnosis and treatment. Symptoms initially viewed as somatization could lead to undertreatment and promote psychological distress, poor coping, and negative patient-provider relationships. Pain and fatigue are important complaints that affect the patient's perception and may need to be addressed with a multidisciplinary approach. Maladaptive cognitive responses can lead to a negative illness perception and impact patient beliefs and concerns over treatment, as well as nonadherence. An underlying inflammatory component in affective disorders has been examined, though whether and how it may interact mechanistically in PsA warrants interest. Cognitive behavioral therapy represents a nonpharmacological treatment modality that can be combined with cytokine-targeted therapy to address both somatic and psychological complaints. Future directions for research include: (1) Elucidating nonspecific manifestations (e.g., subclinical stage, differential with functional syndromes) of PsA and how they impact diagnosis and management; (2) characterizing immune-mediated components of mood disorders in PsA; and (3) whether a bidirectional approach with abrogating inflammation and psychotherapeutic support leads to improved outcomes.

An interdisciplinary intensive outpatient pain program is associated with improved patient activation and key outcomes

Aim: To examine the change in the Patient Activation Measure and physical and psychosocial outcome measures in a military interdisciplinary intensive outpatient program for persistent pain. Materials & methods: Pre- and post-intervention measures, which were also stratified by gender and baseline activation, included patient-reported outcomes and physical function assessment, obtained from 2017 to 2018 program database. Results: The majority of the participants were male (70.9%), with an average age of 29.18 years and pain duration of 4.78 years (n = 103). Patient activation, majority of the patient reported outcomes and functional assessments improved in the overall sample with fewer changes in females on the Defense and Veterans Pain Rating Scale. Conclusion: Improvements were noted on the Patient Activation Measure and majority of the other outcome measures suggesting that service members with persistent pain at any level of patient activation or baseline function, may benefit from an intensive outpatient program.

Predictors and mediators of outcome in cognitive behavioral therapy for chronic pain: the contributions of psychological flexibility

There is now a consensus in the literature that future improvements in outcomes obtained from cognitive behavioral therapy (CBT) for chronic pain will require research to identify patient and treatment variables that help explain outcomes. The first aim of this study was to assess whether pre-treatment scores on measures of psychological (in)flexibility, acceptance, committed action, cognitive (de)fusion, and values-based action predict outcomes in a multidisciplinary, multicomponent, group-based CBT program for adults with chronic pain. The second aim was to assess whether change scores on these same measures mediate outcomes in the treatment program. Participants were 232 people attending treatment for chronic pain. Of the psychological flexibility measures, only pre-treatment scores on the psychological inflexibility scale predicted outcomes; higher scores on this measure were associated with worse outcomes. However, change scores on each of the psychological flexibility measures separately mediated outcomes. The efficacy of CBT for chronic pain may be improved with a greater focus on methods that increase psychological flexibility.

A randomized trial to examine the mechanisms of cognitive, behavioral and mindfulness-based psychosocial treatments for chronic pain: Study protocol

This randomized trial will evaluate the mechanisms of three chronic pain treatments: cognitive therapy (CT), mindfulness meditation (MM), and activation skills (AS). We will determine the extent to which late-treatment improvement in primary outcome (pain interference) is predicted by early-treatment changes in cognitive content, cognitive process, and/or activity level. The shared versus specific role of these mechanisms across the three treatments will be evaluated during treatment (Primary Aim), and immediately post-treatment to examine relapse mechanisms (Secondary Aim). We will enroll 300 individuals with chronic pain (with low back pain as a primary or secondary condition), with 240 projected to complete the study. Participants will be randomly assigned to eight, 1.5 h telehealth group sessions of CT, MM, or AS. Mechanisms and outcomes will be assessed twice daily during 2-week baseline, 4-week treatment period, and 4-week post-treatment epoch via random cue-elicited ecological momentary assessment (EMA); activity level will be monitored during these time epochs via daily monitoring with ActiGraph technology. The primary outcome will be measured by the PROMIS 5-item Pain Interference scale. Structural equation modeling (SEM) will be used to test the primary aims. This study is pre-registered on clinicaltrials.gov (Identifier: NCT03687762). This study will determine the temporal sequence of lagged mediation effects to evaluate rates of change in outcome as a function of change in mediators. The findings will provide an empirical basis for enhancing and streamlining psychosocial chronic pain interventions. Further, results will guide future efforts towards optimizing maintenance of gains to effectively reduce relapse risk.

The Portuguese 35-item Survey of Pain Attitudes applied to Portuguese women with Endometriosis

Background and aims Endometriosis is a gynecologic recurring persistent condition affecting from 8% to 15% of premenopausal women worldwide. About 80% of women with endometriosis have at least one form of chronic pain - a multidimensional experience influenced by a number of psychosocial factors, including pain-related beliefs. The Survey of Pain Attitudes is the most commonly used measure of pain-related beliefs. This study aims to evaluate the psychometric properties of a Portuguese version of a brief version of the SOPA (the SOPA-35) in a sample of Portuguese women with Endometriosis. Methods A sample of 199 Portuguese women with Endometriosis provided demographic and pain history information, and completed a Portuguese version of the SOPA-35 and measures of pain intensity, disability, and psychological function. Analyses were performed to evaluate the factor structure of the Portuguese SOPA-35 items as well as the internal consistency, composite reliability, convergent validity, and concurrent validity of the scale scores. Results Confirmatory factor analysis supported a six-factor solution for a 19-item version of the Portuguese version of the Survey of Pain Attitudes (SOPA-19-P). The six scales evidenced marginal to good reliability (Cronbach's alphas: between 0.60 and 0.84; composite reliability: between 0.61 and 0.84). Four scales evidenced acceptable to good convergent validity (AVE: between 0.51 and 0.63). The findings also supported the concurrent validity of the SOPA-19-P. Conclusions The results support the use of the Portuguese SOPA-19-P for research and clinical purposes with Portuguese women in chronic pain due to endometriosis. Future research is warranted to further develop a European Portuguese version of SOPA. Implications The findings provide psychometric information about the SOPA-19-P. The results are helpful to researchers wishing to study the role of pain-related beliefs and their association with adjustment and treatment outcomes in women with chronic pain due to endometriosis.

Variation in Offer of Operative Treatment to Patients With Trapeziometacarpal Osteoarthritis

PURPOSE

Operative treatment of trapeziometacarpal osteoarthritis (TMC OA) is discretionary. There is substantial surgeon-to-surgeon variation in offers of surgery. This study assessed factors associated with variation in recommendation of operative treatment to patients with TMC OA. Secondarily, we studied factors associated with preferred operative technique and surgeon demographic factors variability in recommendation for operative treatment.

METHODS

We invited all hand surgeon members of the Science of Variation Group to review 16 scenarios of patients with TMC OA and asked the surgeons whether they would recommend surgical treatment for each patient and, if yes, which surgical technique they would offer (trapeziectomy, trapeziectomy with ligament reconstruction and/or tendon interposition, joint replacement, or arthrodesis). Scenarios varied in pain intensity, relief after injection, radiographic severity, and psychosocial symptoms.

RESULTS

Patient characteristics associated with greater likelihood to recommend surgical treatment were substantial pain, a previous injection that did not relieve pain, radiograph with severe TMC OA, and few symptoms of depression. Practice region was the only factor associated with preferred surgical technique and trapeziectomy with ligament reconstruction and/or tendon interposition the most commonly recommended treatment. There was low agreement among surgeons regarding treatment recommendations.

CONCLUSIONS

The notable variation in offers of operative treatment for TMC OA is largely associated with variable attention to subjective factors. Future studies might address the relative influence of surgeon incentives and beliefs, objective pathophysiology, and subjective patient factors on variation in surgeon recommendations.

CLINICAL RELEVANCE

Surgeons' awareness of the potential influence of subjective factors on their recommendations might contribute to efforts to ensure that patient choices reflect what matters most to them and are not based on misconceptions.

Response of the autonomic activity to stress provocation in females with cervicogenic headache compared to asymptomatic controls: a cross-sectional study

BACKGROUND

Because abnormal activity of the autonomic nervous system is associated with chronification of pain, early detection of such dysfunction is important.

AIM

Although several studies highlight autonomic dysfunction in the chronification of headache, no study discussed its role in episodic cervicogenic headache.

DESIGN

Case-controlled cross-sectional single-blind comparative study between women with episodic cervicogenic headache and matched controls.

SETTING

Outpatient setting, Hasselt University.

POPULATION

Autonomic activity of 17 females with episodic cervicogenic headache (26.6±11.6 years) was compared with 17 age, gender and socio-economic matched asymptomatic controls (26.8±11.9 years).

METHODS

Autonomic activity was compared via repeated measures of the activity of the dermal sweat glands (µmho), peripheral circulation (%), electrical activity of the bilateral upper trapezius (μV) before, during and after cognitive stress provocation.

RESULTS

Whereas the autonomic parameters of the control group behaved as expected, participants in the headache group showed: 1) to stress provocation a significant lower dermal sweat gland activity (3.03±0.44 vs. 4.19±0.91 µmho, P<0.0001), higher vasodilatation (-5.56±1.45% vs. -5.61±1.85%, P=0.03), lower activity of the left upper trapezius (0.21±0.44 vs. 0.89±0.59 µV, P=0.03), significant less recuperation of the dermal sweat gland activity (-2.57±0.40 vs. -3.29±0.84 µmho, P<0.0001); 2) no recuperation of the activity (μV) of the left (P=0.83) and right (P=0.99) upper trapezius; 3) from stress provocation to recuperation a significant negative correlation (ρ=0.69, P=0.04) between dermal sweat gland and right upper trapezius activity.

CONCLUSIONS

Females with episodic cervicogenic headache reacted less to cognitive stress provocation. Recuperation after such provocation was absent. More research is needed to associate autonomous responses with a possible chronification process.

CLINICAL REHABILITATION IMPACT

A dysfunctional reaction to cognitive stress could be a threat to allostasis.

Quality of life among men with spinal cord injury in Lebanon: A case control study

BACKGROUND

Spinal cord injury (SCI) is a permanent disability which negatively affects individuals' health and particularly their quality of life.

OBJECTIVE

To assess the quality of life (QoL) among Lebanese men with spinal cord injury and to compare it to a healthy control group.

METHODS

A case control study was conducted. Fifty-one Lebanese patients with spinal cord injury and 51 age- sex-matched healthy persons were included in the study.

RESULTS

Compared to healthy controls, the mean scores of eight domains of SF-36 were significantly lower in SCI group: physical functioning (PF) (26.5 vs 87; p value <0.0001), role limitations due to physical (RP) (57.8 vs 93.6; p value <0.0001), bodily pain (BP) (60.5 vs 90.7; p value, 0.0001), general health (GH) (49.5 vs 76.6; p value <0.0001), vitality (VT) (51.2 vs 71.3; p value <0.0001), social functioning (SF) (68.9 vs 91.2; p value <0.0001), role limitations due to emotional problems (RE) (71.2 vs 91.5; p value 0.003) and mental health (MH) (62.9 vs 79; p value <0.0001). Concerning PCS and MCS scores, SCI patients reported significantly lower scores than control group (p value <0.0001).

CONCLUSION

Participants with SCI reported reduced QoL in comparison with normal individuals.

Pain appraisal and quality of life in 108 outpatients with rheumatoid arthritis

Individual differences in emotional functioning, pain appraisal processing, and perceived social support may play a relevant role in the subjective experience of pain. Due to the paucity of data regarding individuals with Rheumatoid Arthritis (RA), the present study aimed to examine pain intensity, emotional functioning (psychological distress and alexithymia), pain appraisal (pain beliefs, pain catastrophizing, and pain-related coping strategies) and social support, and their relationships with the health-related quality of life (HRQoL) in patients with RA. Data were collected from 108 female patients diagnosed with RA. Clinically relevant levels of depressive and anxiety symptoms assessed by the HADS subscales were present in 34% and 41% of the patients, respectively, and about 24% of them exhibited the presence of alexithymia. The results of hierarchical multiple regression analyses showed that pain intensity, alexithymia, the maladaptive beliefs regarding the stability of pain and the coping strategy of guarding explained 54% of the variance in the physical component of HRQoL (p < 0.001). Depression subscale of the HADS, alexithymia, the coping strategy of resting, and the rumination factor of pain catastrophizing significantly explained 40% of the variance in the mental component of HRQoL (p < 0.001). The present findings provide evidence regarding the importance of emotional functioning and pain appraisal in the negative impact of RA on patients' quality of life. These findings provide additional evidence for the biopsychosocial model of chronic pain, further supporting the complex interaction between emotional, cognitive, and behavioral processes in patients with chronic pain.

Cross-cultural adaptation, test-retest reliability, and construct validity of the Thai version of the University of Washington Pain-Related Self-Efficacy Scale

INTRODUCTION

One psychosocial factor in the biopsychosocial model is pain-related self-efficacy, which has been shown to be a strong predictor of response to pain treatment.

OBJECTIVES

To cross-culturally adapt the University of Washington Pain-Related Self-Efficacy Scale (UW-PRSE6) into Thai and evaluate its psychometric properties.

METHODS

The study was approved by the Chulalongkorn University Human Ethics Committee (COA No. 156/2018). The original UW-PRSE6 was cross-culturally adapted using the Functional Assessment of Chronic Illness Therapy translation methodology. Two hundred forty-one individuals with chronic low back pain completed the Thai version of UW-PRSE6 (T-UW-PRSE6), Thai Fear Avoidance Beliefs Questionnaire (T-FABQ), and Thai Medical Outcome Study Short-Form 36 (T-SF-36). A subset of 152 participants completed the T-UW-PRSE6 again after a 7-day interval. Cronbach's alpha and intraclass correlation coefficients were calculated to estimate internal consistency and test-retest reliability, respectively. The construct validity of the T-UW-PRSE6 was evaluated by computing Spearman correlation coefficients between the T-UW-PRSE6 score and the measures of the validity criterion variables.

RESULTS

The T-UW-PRSE6 had good internal consistency (Cronbach's alpha = 0.85) and moderate test-retest reliability (intraclass correlation coefficient [2,1] = 0.72). The T-UW-PRSE6 was negatively correlated with the T-FABQ Work and Physical Activity subscales (rs = -0.34 and -0.34, respectively) and positively correlated with the General Health, Physical Functioning, Role Physical, Role Emotional, Social Functioning, Bodily Pain, Vitality, and Mental Health scales of the T-SF-36 (rs = 0.38, 0.42, 0.54, 0.51, 0.47, 0.54, 0.41, and 0.40, respectively).

CONCLUSION

The T-UW-PRSE6 demonstrated acceptable psychometric properties for assessing pain-related self-efficacy in individuals with chronic low back pain, making available a measure for facilitating future cross-cultural research on pain self-efficacy.

Association Between Catastrophizing and Dizziness-Related Disability Assessed With the Dizziness Catastrophizing Scale

Importance

Catastrophizing is a maladaptive thought process that involves irrational fear and worry about anticipated or actual symptoms. Although clinically relevant, the role of catastrophizing in patients with chronic dizziness or imbalance has not yet been explored to our knowledge.

Objectives

To validate a measure of dizziness catastrophizing and to assess its association with dizziness-related disability compared with other negative affect constructs (eg, anxiety and depression).

Design, Setting, and Participants

For this retrospective medical record review, the Dizziness Catastrophizing Scale (DCS), a dizziness-specific catastrophizing assessment tool, was adapted from the previously validated Pain Catastrophizing Scale. Psychometric evaluation of the DCS was performed. In addition, the associations of dizziness catastrophizing and positive and negative affectivity with dizziness-related disability were assessed using structural equation modeling and regression analyses. Data were collected using a retrospective medical record review from April 27, 2010, to June 25, 2014. The dates of analysis were June 3 to August 15, 2017. The setting was the Multidisciplinary Neurotology Clinic at the Toronto General Hospital (Toronto, Ontario, Canada). Participants were 457 adult outpatients with dizziness or imbalance who were referred to the clinic.

Main Outcomes and Measures

Psychometric properties of the DCS and its association with dizziness-related disability, as measured with the Dizziness Handicap Inventory.

Results

Among 457 patients (mean [SD] age, 53.4 [15.4] years; 154 [33.7%] male), the DCS demonstrated good convergent (r = 0.78, P < .001) and discriminant validity (r = -0.40, P < .001) with the negative and positive affectivity, respectively; internal consistency (α = .95); and test-retest reliability (intraclass correlation coefficient, 0.92; P < .001 at the 95% CI). An exploratory dimension reduction analysis revealed a single latent component of the DCS. The results of the structural equation modeling and regression analyses revealed that dizziness catastrophizing, although associated with negative affectivity (eg, symptoms of anxiety and depression), was independently associated with dizziness-related disability (standardized β = 0.378; P < .001). Furthermore, a strong association was found between catastrophizing and dizziness-related disability across different dizziness-related diagnoses (r ≥ 0.6; P < .001).

Conclusions and Relevance

In this study, the DCS was a valid and reliable measure for evaluating catastrophic thinking in patients with dizziness, which was independently associated with dizziness-related disability. Future studies should investigate the influence of alleviating symptoms of catastrophizing on functional outcomes in patients with dizziness or imbalance, the results of which will help guide novel approaches to the clinical care of patients with chronic dizziness.

Psychology of Chronic Pelvic Pain: Prevalence, Neurobiological Vulnerabilities, and Treatment

Patients with pelvic pain suffer from psychological conditions at a disproportionately high rate compared with their peers. We review environmental, genetic, inflammatory, and neurobiological factors that increase vulnerability to developing both of these conditions. We review treatment strategies for chronic pelvic pain in patients who have comorbid psychological conditions, including both nonpharmacologic and pharmacologic options.

How does reduction in pain lead to reduction in disability in patients with musculoskeletal pain?

Purpose

Reduction in pain following multidisciplinary treatment is most often associated with a reduction in disability. To further elaborate the relationship between pain intensity and disability, the present study investigated three main questions: first, whether multidisciplinary treatment leads to a significant improvement in pain, disability and psychological variables (depression, pain acceptance and catastrophizing). Second, it was examined whether pain reduction may account for significant changes in the psychological variables (pre- to follow-up change scores). Finally, it was analyzed whether the psychological changes mediate the association between reduction in pain and in disability after controlling for age, sex and pain history.

Patients and methods

Patients suffering from chronic musculoskeletal pain (n=279) attended a German inpatient multidisciplinary program lasting 15 consecutive days on average, with self-report data collected at pretreatment, posttreatment and three-month follow-up.

Results

Repeated measures ANOVAs showed a significant improvement in pain intensity, disability, pain acceptance, catastrophizing and depression at posttreatment and follow-up. Univariate regression analyses revealed that changes in pain intensity accounted for significant changes in depression, pain catastrophizing and pain acceptance (pre- to follow-up change scores). The results of Multiple Mediation Procedure showed that pain reduction did affect reduction in disability through improvement of depression, catastrophizing and acceptance.

Conclusion

Our findings support a cognitive-behavioral model of pain that posits an important role for pain-related cognitive and emotional processes in long-term outcomes following multidisciplinary pain treatment, in particular for the modulation of disability due to pain. The results add evidence to the notion that pain-related cognitions are dynamic features varying over time dependent on the internal situation.

Perspective

The current findings are relevant to the management of patients with musculoskeletal pain. The results support the notion that, in contrast with the view of enduring personality traits, pain-related cognitions and emotions reflect a situational response that varies over time.

Measuring Pain Catastrophizing and Pain-Related Self-Efficacy: Expert Panels, Focus Groups, and Cognitive Interviews

PURPOSE

Pain-related self-efficacy and pain catastrophizing are important psychosocial determinants of pain and can be therapeutic targets for chronic pain management. Advances in psychometric science have made shorter or dynamically administered instruments possible. The aim of this study was to generate and test candidate items for two new patient-reported outcome measures of pain-related self-efficacy and pain catastrophizing.

METHODS

An expert panel of pain clinicians and researchers was convened to establish construct definitions of pain-related self-efficacy and pain catastrophizing and guide item development. Two patient advisors provided guidance throughout the project. Nineteen people with chronic pain participated in focus groups about their perspectives and experiences related to pain-related self-efficacy and pain catastrophizing. Twenty-two people with chronic pain participated in cognitive interviews to test proposed candidate items.

RESULTS

Saturation was reached after three focus groups with no new subdomains identified by participants in the third focus group. Following cognitive interviews, five of the 48 initial pain-related self-efficacy candidate items were dropped and seven required substantial revision resulting in 43 pain-related self-efficacy candidate items. After two rounds of cognitive interviews, ten items were eliminated and ten substantially revised, resulting in a set of 30 from the initial 43 pain catastrophizing candidate items.

CONCLUSION

This article summarizes results of the qualitative phase of the development of new measures of pain-related self-efficacy and pain catastrophizing. Candidate items will be field tested with a large sample of people with chronic pain and the data will be used to calibrate items to an item response theory model. Resulting item banks and short forms will be made publicly available to researchers and clinicians.

Predicting factors of outcome in multidisciplinary treatment of chronic neuropathic pain

Purpose

Evidence of the effectiveness of multidisciplinary treatment with a focus on neuropathic pain is still rare. The present study investigated whether multidisciplinary treatment leads to improvement of neuropathic pain in outcome (pain intensity and disability) and psychological (depression, pain acceptance, and catastrophizing) variables at posttreatment and 3-month follow-up. We examined whether and to what extent psychological changes can predict long-term outcome at 3-month follow-up, when other variables are controlled for (baseline characteristics and changes in pain parameters).

Patients and methods

Patients suffering from a chronic neuropathic pain condition (n=141) attended an inpatient multidisciplinary program lasting about 15 continuous days with self-report data collected at pretreatment, posttreatment, and 3-month follow-up.

Results

Repeated-measures ANOVAs showed a significant improvement of pain intensity, disability, pain acceptance, catastrophizing, and depression at posttreatment. These improvements remained stable over the 3-month follow-up for all variables except for depression. The inclusion of psychological changes in multiple regression analyses greatly increased the variance in outcome, explained by baseline characteristics and changes in pain parameters.

Conclusion

The results could help clinicians to determine which variables should be emphasized during inpatient treatment and during the follow-up period, in order to maintain the gains after an inpatient multidisciplinary treatment for neuropathic pain.

Perspective

The present study demonstrates the beneficial effects of an inpatient multidisciplinary program for neuropathic pain and further question the resistant nature of neuropathic pain to treatment. The results add evidence to the relevance of cognitive-behavioral models of pain positing an important role for pain-related thoughts and emotions in long-term outcome following multidisciplinary pain treatment.

Pain management strategies among persons with long-term shoulder pain after stroke - a qualitative study

OBJECTIVE:

To explore strategies that persons with persistent shoulder pain after stroke use to manage their pain in daily life.

DESIGN:

A qualitative study using semi-structured face-to-face interviews, analysed by content analysis.

SETTING:

A university hospital.

SUBJECTS:

Thirteen community-dwelling persons (six women; median age: 65 years; range 57-77) with shoulder pain after stroke were interviewed median two years after the pain onset.

RESULTS:

An overall theme 'Managing shoulder pain by adopting various practical and cognitive strategies' emerged from the analysis. Three categories were identified: (1) practical modifications to solve daily life problems; (2) changed movement patterns and specific actions to mitigate the pain, by non-painful movements, avoidance of pain-provoking activities and various pain distracting activities and (3) learned how to deal with the pain mentally. Several strategies were used simultaneously and they were experienced successful to various degrees.

CONCLUSION:

The findings in the present study indicate that persons with persistent shoulder pain after stroke use both practical and cognitive strategies to manage their pain.

A Qualitative Examination of Pain Centrality Among Veterans of Iraq and Afghanistan Conflicts

Objective

Centrality of pain refers to the degree to which a patient views chronic pain as integral to his or her life or identity. The purpose of this study was to gain a richer understanding of pain centrality from the perspective of patients who live with chronic pain.

Methods

Face-to-face interviews were conducted with 26 Veterans with chronic and disabling musculoskeletal pain after completing a stepped care intervention within a randomized controlled trial. Qualitative data were analyzed using an immersion/crystallization approach. We evaluated the role centrality plays in Veterans’ lives and examined whether and how their narratives differ when centrality either significantly decreases or increases after participation in a stepped care intervention for chronic pain.

Results

Our data identified three emergent themes that characterized pain centrality: 1) control, 2) acceptance, and 3) preoccupation. We identified five characteristics that distinguished patients’ changes in centrality from baseline: 1) biopsychosocial viewpoint, 2) activity level, 3) pain communication, 4) participation in managing own pain, and 5) social support.

Conclusions

This study highlights centrality of pain as an important construct to consider within the overall patient experience of chronic pain.

Does a Program Based on Cognitive Behavioral Therapy Affect Kinesiophobia in Patients Following Total Knee Arthroplasty? A Randomized, Controlled Trial With a 6-Month Follow-Up

BACKGROUND

To evaluate the effects of a cognitive behavioral therapy (CBT) program on kinesiophobia, knee function, pain and pain catastrophizing in patients following total knee arthroplasty (TKA).

METHODS

This was a parallel-group, randomized, controlled pilot study in which 100 patients who exhibited kinesiophobia after TKA were randomly assigned to participate in a CBT (experimental group) or standard care (control group) program. Each group included 50 patients. Before intervention (preintervention), 4 weeks after intervention (postintervention), and 6 months after the end of intervention (follow-up), patients were assessed via the Tampa Scale for Kinesiophobia, the Pain Catastrophizing Scale, a numerical rating scale, and the Hospital for Special Surgery knee rating scale. Repeated-measures analysis of variance was used to test the significance of each outcome measure.

RESULTS

The CBT program had significant group (P < .001), time (P < .001), and group-by-time interaction (P < .001) effects on kinesiophobia, pain catastrophizing, and knee function, and these effects lasted for at least 6 months after the end of the intervention. Pain was reduced in both groups after the intervention, but there were significant time and group effects (P = .003) in favor of the experimental group.

CONCLUSION

The CBT program was superior to standard care in reducing kinesiophobia, pain catastrophizing, and knee pain and in enhancing knee function in patients who have a high level of kinesiophobia following TKA. The treatment effect was clinically significant and lasted for at least 6 months after the end of the intervention.

Pain Beliefs and Quality of Life in Young People With Disabilities and Bothersome Pain

OBJECTIVES

Pain beliefs have been hypothesized to play an important role in pediatric pain. However, research examining the associations between pain-related beliefs and measures of function in youths with disabilities is limited.

METHODS

In total, 84 youths (mean age, 14.26 y; SD, 3.27) with physical disabilities who indicated they also had bothersome pain were interviewed and asked to rate their average pain intensity in the past week and to complete measures of pain-related beliefs and health-related quality of life.

RESULTS

A number of pain beliefs were associated with different physical and psychosocial function domains, although different beliefs appeared to play different roles, depending on the function domain examined. Across all of the health-related quality-of-life domains studied, a belief that pain is influenced by one's emotions was associated with lower levels of function. No differences were found in pain beliefs related to age. In addition, a small difference in pain beliefs was found for sex; specifically, girls were more likely than boys to endorse the belief that pain is influenced by emotions.

DISCUSSION

The findings provide new information regarding the role that pain beliefs have in predicting function and have important clinical implications regarding how youth with physical disabilities and pain might be most effectively treated.

Mindfulness-based cognitive therapy for headache pain: An evaluation of the long-term maintenance of effects

OBJECTIVES

This study aimed to examine the durability of gain patterns following an 8-week Mindfulness-Based Cognitive Therapy (MBCT) for headache pain program.

DESIGN

A secondary analysis of a randomized controlled trial was conducted. Participants (N=19) were individuals with headache pain who completed both the MBCT program as well as a 6-month follow-up assessment at a headache clinic or a university psychology clinic. Standardized measures of the primary outcomes (pain intensity and pain interference) and secondary outcomes (pain catastrophizing, mindfulness, activity engagement, pain willingness, and self-efficacy) were administered. Paired-samples t tests and effect sizes were examined.

RESULTS

Significant (uncorrected ps<.05) pre- to post-treatment gains were found for pain intensity, pain interference, pain catastrophizing, activity engagement and self-efficacy, and these gains were maintained at 6-months post-treatment. Effect sizes for the significant changes from pre- to post-treatment, and from pre-treatment to follow-up were mostly consistent across epochs (.62≤ds≤-1.40), indicating steady maintenance of effects. Improvement in mindfulness and pain willingness was non-significant immediately post-treatment and at follow-up, with small effects observed.

CONCLUSIONS

This study adds to a growing body of literature supporting the durability of MBCT for painful conditions. Results indicated a consistent pattern of maintenance of treatment-related gains across a number of key pain-related outcomes. Future research with a larger sample is needed to investigate the mechanisms underlying these continued gains in order to optimize targeted relapse-prevention.

Psychological interventions influence patients' attitudes and beliefs about their chronic pain

Background

Patients' changing attitudes and beliefs about pain are considered as improvements in the treatment of chronic pain. Multidisciplinary approaches to pain allow modifications of coping strategies of patients, from passive to active.

Methods

We investigate how two therapeutic treatments impact patients' attitudes and beliefs regarding pain, as measured with the Survey of Pain Attitudes (SOPA). We allocated 415 patients with chronic pain either to psychoeducation combined with physiotherapy, self-hypnosis combined with self-care learning, or to control groups. Pain intensity, global impression of change, and beliefs and attitudes regarding pain were assessed before and after treatment.

Results

Our main results showed a significant effect of psychoeducation/physiotherapy on control, harm, and medical cure SOPA subscales; and a significant effect of self-hypnosis/self-care on control, disability and medical cure subscales. Correlation results showed that pain perception was negatively associated with control, while positively associated with disability, and a belief that hurt signifies harm. Patients' impression of improvement was associated with greater control, lower disability, and lower belief that hurt signifies harm.

Conclusions

The present study showed that self-hypnosis/self-care and psychoeducation/physiotherapy were associated with patients' evolution of coping strategies from passive to active, allowing them to reduce pain perception and improve their global impression of treatment effectiveness.

Effects of a Pain Catastrophizing Induction on Sensory Testing in Women with Chronic Low Back Pain: A Pilot Study

Pain catastrophizing, a pattern of negative cognitive-emotional responses to actual or anticipated pain, maintains chronic pain and undermines response to treatments. Currently, precisely how pain catastrophizing influences pain processing is not well understood. In experimental settings, pain catastrophizing has been associated with amplified pain processing. This study sought to clarify pain processing mechanisms via experimental induction of pain catastrophizing. Forty women with chronic low back pain were assigned in blocks to an experimental condition, either a psychologist-led 10-minute pain catastrophizing induction or a control (10-minute rest period). All participants underwent a baseline round of several quantitative sensory testing (QST) tasks, followed by the pain catastrophizing induction or the rest period, and then a second round of the same QST tasks. The catastrophizing induction appeared to increase state pain catastrophizing levels. Changes in QST pain were detected for two of the QST tasks administered, weighted pin pain and mechanical allodynia. Although there is a need to replicate our preliminary results with a larger sample, study findings suggest a potential relationship between induced pain catastrophizing and central sensitization of pain. Clarification of the mechanisms through which catastrophizing affects pain modulatory systems may yield useful clinical insights into the treatment of chronic pain.

Pain Catastrophizing and Its Relationship with Health Outcomes: Does Pain Intensity Matter?

Pain catastrophizing is known to contribute to physical and mental functioning, even when controlling for the effect of pain intensity. However, research has yet to explore whether the strength of the relationship between pain catastrophizing and pain-related outcomes varies across pain intensity levels (i.e., moderation). If this was the case, it would have important implications for existing models of pain and current interventions. The present investigation explored whether pain intensity moderates the relationship between pain catastrophizing and pain-related outcomes. Participants were 254 patients (62% women) with heterogeneous chronic pain. Patients completed a measure of pain intensity, pain interference, pain catastrophizing, and physical and mental health. Pain intensity moderated the relationship between pain catastrophizing and pain interference and between pain catastrophizing and physical health status. Specifically, the strength of the correlation between pain catastrophizing and these outcomes decreased considerably as pain intensity increased. In contrast, pain intensity did not moderate the relationship between pain catastrophizing and mental health. Study findings provide a new insight into the role of pain intensity (i.e., moderator) in the relationship between pain catastrophizing and various pain-related outcomes, which might help develop existent models of pain. Clinical implications are discussed in the context of personalized therapy.

The determinants of coping with pain in chronically ill geriatric patients - the role of a sense of coherence

BACKGROUND

Given the rising population of the elderly in modern societies, the concern for their good functioning poses a challenge for the 21st century medicine and social services. Senior citizens are at an increased risk of developing chronic conditions, which in turn increase discomfort associated with physiological processes of aging. Sensations of pain have a particular influence on the mentioned discomfort, and pain is prevalent among older people. Therefore, from the perspective of an elderly person and senior care, it is crucial to identify determinants of effective coping with chronic pain.

OBJECTIVES

The aim of the research was to assess the relationship between a sense of coherence (SOC) and pain-coping strategies in chronically ill seniors. A total number of 188 individuals were included in the study, of whom 117 were female subjects and 71 were male subjects, with a mean age of 68.38 (standard deviation [SD] =6.35) years in the studied group. Subjects were sampled based on a diagnosis of a chronic medical illness with chronic pain as one of the major symptoms.

METHODS

The Polish adaptation of the Orientation to Life Questionnaire (SOC-29) to assess an SOC, the Coping Strategies Questionnaire (CSQ) to assess pain-coping strategies, and the visual analog scale (VAS) to assess pain intensity were used in the study.

RESULTS AND CONCLUSION

The mean score of respondents' SOC was 133.44 (SD =24.35). Among most common pain-coping strategies used by the respondents were prayer and hope, and the declaration of coping with pain while redefining pain was the least often used coping strategy in the studied group. Individuals with stronger SOC were less prone to catastrophizing and more often declared that they were coping with and could control and reduce pain.

[Multimodal pain therapy. Current situation]

A multidisciplinary approach for the management of patients with chronic pain is now well-established in many countries, especially in situations involving a complex disease process in the sense of a biopsychosocial model. Both the efficacy and cost-effectiveness of multidisciplinary pain treatment programs and their superiority compared to unimodal therapy has been documented in a number of studies, reviews and meta-analyses, in particular for patients suffering from chronic low back pain. Nevertheless, there are still major shortcomings concerning the definition of multimodal and multidisciplinary treatment and the quality of structures and processes, compared for example to the standards defined by the German Pain Society (Deutsche Schmerzgesellschaft). Furthermore, there is still no consensus on specific therapeutic approaches, the differentiation between responders and non-responders as well as on the tools required for measurement. All these questions will have to be answered by concerted efforts in a multicenter setting.

Acceptance and Commitment Therapy and Selective Optimization with Compensation for Institutionalized Older People with Chronic Pain

OBJECTIVE

Recent studies support the efficacy of Acceptance and Commitment Therapy (ACT) with people with chronic pain. In addition, Selective Optimization with Compensation strategies (SOC) can help the elderly with chronic pain to accept their chronic condition and increase functional autonomy. Our aim was to analyze the efficacy of an ACT treatment program combined with training in SOC strategies for elderly people with chronic pain living in nursing homes.

METHODS

101 participants (mean age = 82.26; SD = 10.00; 78.6% female) were randomized to the intervention condition (ACT-SOC) or to a minimal support group (MS). Complete data are available for 53 participants (ACT-SOC: n = 27; MS: n = 26). Assessments of functional performance, pain intensity, pain acceptance, SOC strategies, emotional well being and catastrophizing beliefs were done preintervention and postintervention.

RESULTS

Significant time by intervention changes (P = 0.05) were found in acceptance, pain related anxiety, compensation strategies, and pain interference in walking ability. Simple effects changes were found in acceptance (P = 0.01), selection strategies (P = 0.05), catastrophizing beliefs (P = 0.03), depressive symptoms (P = 0.05), pain anxiety (P = 0.01) and pain interference in mood and walking ability (P = 0.03) in the ACT-SOC group. No significant changes were found in the MS group.

CONCLUSIONS

These results suggest that an ACT intervention combined with training in SOC strategies could help older people with pain to improve their emotional well being and their functional capability.
