Mindfulness-based stress reduction and cognitive behavioral therapy for chronic low back pain: similar effects on mindfulness, catastrophizing, self-efficacy, and acceptance in a randomized controlled trial

The relationship between mindfulness and depression: examining the chain mediating role of shyness and core self-evaluation

BACKGROUND

There is evidence to suggest that individuals with the personality trait of shyness are more prone to depression, and a possible key factor in the process of shyness leading to depression is core self-evaluation. Given the prevalence and cross-cultural nature of shyness in humans, it is crucial to understand the factors that reduce shyness, enhance core self-evaluation, and ultimately lower depression. This study aims to examine whether mindfulness affects depression through sequential pathways involving shyness and core self-evaluation.

METHOD

We adopted a two-phase sampling method, recruiting an initial sample of 646 college students (Sample 1). We conducted a questionnaire survey using the Chinese version of the Five Factor Mindfulness Scale, the revised Cheek and Buss Shyness Scale, the Core Self-Evaluation Scale, and the Chinese version of the Beck Depression Inventory-II. We constructed a chain mediation model to examine the relationship between mindfulness and depressive symptoms, with shyness and core self-evaluation as mediating variables. Subsequently, based on Sample 1, we purposively selected a subsample of 269 college students with higher shyness scores (Sample 2) and re-examined the chain mediation effect.

RESULTS

Higher levels of mindfulness were associated with lower levels of depressive symptoms, and this relation was mediated through shyness and core self-evaluation.

CONCLUSIONS

These results highlight that mindfulness can influence depression through the sequential pathway of shyness and core self-evaluation, and the importance of considering mindfulness practices in psychological interventions to help college students, especially shy college students, to reduce their shyness levels, improve core self-evaluation levels, and ultimately prevent and/or treat their depressive symptoms.

How therapist effects shape pain-related outcome improvement in psychological treatments for chronic pain

Psychological chronic pain treatments have variable efficacy across individual patients, and on average tend to produce modest effects. In order to improve treatment outcomes, the past decade has seen a rapid increase in research focused on determining the mechanisms underlying treatment-related gains. The near exclusive focus of this research has been on uncovering patient-related mediators and moderators. However, treatment is delivered within the context of a patient-therapist dyad, and the dynamic contribution of therapist-related factors in influencing this dyad and patient outcomes has remained largely unexamined. The purpose of the current paper is to consider the unique contributions of therapist-related factors within our proposed "Top 3" dynamic, candidate contextual mechanisms: therapeutic working alliance, group climate/cohesion (i.e., in group therapy), and therapist quality. We define these process variables, identify validated measures, and review research documenting their effects on outcomes, drawing from the pain and broader psychotherapy literature. It is well established that some therapists are more effective than others, with so-called exceptional (i.e., not merely competent) therapists shown to produce effect sizes twice as large and demonstrate up to ten times better patient response rates. We focus on identifying the behaviors that such exceptional therapists engage in to harness the working alliance, build and maintain group cohesion and skilfully deliver and train patients in various therapeutic techniques. Future pain treatment outcome research evaluating the role of therapists in these "Top 3" process variables has the potential to provide novel insights into treatment mechanisms, inform therapist training, and to advance precision medicine.

Psychological Support for Chronic Low Back Pain: A Systematic Review on the Validity of a Growing Remote Approach

BACKGROUND AND OBJECTIVE

Low back pain (LBP) is one of the main health problems imposing a significant burden both personally and socially. It is estimated that 70-85% of people experience LBP during their lifetime, with nearly 20% of cases becoming chronic (CLBP). Interest in psychosocial factors and their correlations with the onset and outcome of low back pain has increased in recent years. The primary objective of this study is to demonstrate the validity and promote the adoption of psychological therapies delivered through remote platforms for the treatment and management of chronic pain related to LBP.

METHODS

The clinical studies we reviewed in our research were identified from the PubMed, Web of Science, Scopus, and Cochrane Library databases. Out of the initial 11,859 studies, only 20 met the inclusion criteria.

RESULTS

The results of our study confirm the effectiveness of psychological therapy delivered remotely in the treatment and management of chronic pain caused by low back pain. This highlights the importance of psychological intervention to improve the quality of life for these patients. Remote therapy can indeed facilitate treatment adherence and patient empowerment.

CONCLUSION

Living with a chronic illness requires continuous support and the development of personalized interventions where the patient is accompanied and supported daily through active intervention. This underscores the importance of expanding the availability of traditionally available psychological strategies to remote delivery to support a growing number of people affected by CLBP.

Development and Initial Validation of Mindfulness-Based Pain Reduction (MBPR) in Patients With Chronic Low Back Pain

Purpose

Mindfulness-Based Stress Reduction (MBSR) has shown efficacy for alleviating chronic low back pain (cLBP) and is included in current treatment guidelines. However, benefits are moderate. We aimed to optimize MBSR for chronic pain by using recent research to develop Mindfulness-Based Pain Reduction (MBPR) and test it in patients with cLBP.

Patients and Methods

Phase 1: We modified the MBSR curriculum with theory-driven components and convened focus groups with local and international mindfulness and clinical pain management experts to refine an 8-week MBPR program. Phase 2: We recruited participants with cLBP from Northern California using outreach in newsletters, social media, and other methods to test and iteratively modify the curriculum. MBPR was delivered in a group format by videoconference. The first three groups received MBPR; a fourth group was randomized to MBSR or MBPR to assess randomization feasibility. We assessed feasibility and acceptability by attendance, practice logs, and exit interviews. We assessed changes in patient-reported outcome measures for low back pain trials using a single arm (treatment group only) approach at 2 and 6 months with linear mixed models (primary: pain intensity and interference (PEG) scores).

Results

Phase 1: The MBPR curriculum included: 1) mindful interoceptive exposure to pain, 2) pain neuroscience education, and 3) yoga postures specifically for cLBP. Phase 2: we enrolled 58 patients in 4 cohorts; 49 completed post-intervention and 41 completed 6-month follow-up assessments; 29 of the 41 received MBPR. Participants attended a mean of 80% of sessions and 23 of 24 participants accepted randomization in the 4th cohort. Mean PEG scores improved for 20 of 29 MBPR participants in a clinically meaningful way (PEG scores >30%).

Conclusion

MBPR was feasible and acceptable. Two-thirds of MBPR participants experienced clinically meaningful improvements in pain intensity and interference scores. MBPR warrants further investigation through a randomized, controlled trial.

Treatment mechanism and outcome decoupling effects in cognitive therapy, mindfulness-based stress reduction, and behavior therapy for chronic pain

ABSTRACT

Findings suggest that cognitive therapy (CT), mindfulness-based stress reduction (MBSR), and behavior therapy (BT) for chronic pain produce improvements through changes in putative mechanisms. Evidence supporting this notion is largely based on findings showing significant associations between treatment mechanism variables and outcomes. An alternative view is that treatments may work by reducing or decoupling the impact of changes in mechanism variables on changes in outcomes. We examined the degree to which relationships between previous changes in potential treatment mechanisms and subsequent changes in outcomes changed as treatment progressed and vice versa. Cognitive therapy, MBSR, BT, and treatment as usual (TAU) were compared in people with chronic low back pain (N = 521). Eight individual sessions were administered with weekly assessments of putative treatment mechanisms and outcomes. Lagged analyses revealed mechanism × session number interactions and outcome × session number interactions, such that associations between mechanism and outcome variables were strong and significant in the first third of treatment, but weakened over time and became nonsignificant by the last third of treatment. These effects were similar across treatment conditions but did not emerge among people undergoing TAU. Results suggest that during the course of CT, MBSR, and BT, the links between changes in treatment mechanism variables became decoupled from subsequent changes in outcomes and vice versa. Thus, starting by midtreatment and continuing into late treatment, participants may have learned through participation in the treatments that episodes of maladaptive pain-related thoughts and/or spikes in pain need not have detrimental consequences on their subsequent experience.

An interdisciplinary virtual group program addressing the FINER points of chronic pain management: An exploratory analysis of functional outcomes

OBJECTIVES

Chronic pain is multifactorial and has large social and economic costs. Comprehensive pain management through an interdisciplinary approach addressing the biopsychosocial model of pain is beneficial. The purpose of this study was to assess the feasibility and functional outcomes following participation in the 8-week virtual interdisciplinary Functional Integrative Restoration (FINER) program.

DESIGN

Cohort study.

SETTING

Virtual platform (Zoom) utilized by participants and clinicians within a large academic institution.

SUBJECTS

44 individuals with chronic pain meeting study criteria who participated in the virtual FINER program from September 2021 to April 2023 were included in final analysis.

METHODS

Participants attended twice weekly seminars and group sessions focused on pain education, lifestyle medicine, integrative medicine, and psychological therapies virtually and completed pre- and post-program surveys. Outcomes included the Pain Catastrophizing Scale (PCS), Tampa Scale of Kinesiophobia (TSK), and Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29). Qualitative feedback was also obtained.

RESULTS

From September 2021 to April 2023, 44 adult FINER participants with chronic low back and/or neck pain completed pre- and post-intervention surveys. We observed significant improvements in PCS, TSK, and various domains of the PROMIS-29, including pain interference, participation, physical function, and sleep, with modest effect sizes.

CONCLUSIONS

The FINER program reduced self-reported functional outcomes related to the participants' chronic pain. Positive qualitative feedback from FINER participants suggested mental and physical health benefits. Future investigation will include a larger cohort and will deploy active (patient-reported outcomes) and passive (mobility and sociability) digital measures to further characterize functional changes.

Mediators and Moderators of two online interventions for managing pain, fear of progression and functional ability in rheumatoid arthritis

This is a secondary analysis of a trial comparing online mindfulness-based stress reduction with cognitive-behaviour therapy for people with rheumatoid arthritis. Both interventions were administered over eight weeks with five lessons and accompanied by weekly therapist contact. For the purposes of this study, we investigated the pain severity, fear of progression and functional ability as the outcome variables because the treatments had differential effects on these three outcomes but had equivalent effects on other variables. We examined mediators and moderators of relative treatment efficacy of mindfulness based stress reduction (n = 91) versus cognitive-behaviour therapy (n = 103) for these outcomes. For pain severity, no significant mediators or moderators were identified. However, amongst those with low pain severity, mindfulness-based stress reduction was more efficacious than cognitive-behaviour therapy for fears of progression. Furthermore, mindfulness-based stress reduction was more efficacious than cognitive-behaviour therapy for functional ability for those with high trait mindfulness at baseline. Changes in fear of progression during treatment fully mediated the effect of treatment group on functional ability over follow-up. While both online mindfulness-based stress reduction and cognitive-behaviour therapy were efficacious for people with rheumatoid arthritis, mindfulness-based stress reduction was more effective in reducing fears of progression and improving functional ability for those with low levels of pain severity and high levels of mindfulness at baseline, respectively. These results highlight the importance of treating fear of progression for people with rheumatoid arthritis as reductions in fears of progression over treatment led to improvements in functional ability six months later.

Perceived discrimination and pain outcomes among black adults with chronic musculoskeletal pain: identifying modifiable psychosocial risk factors

Chronic musculoskeletal pain (CMP) is highly prevalent, frequently associated with negative health outcomes, and disproportionately impacts Black Americans. Perceived racial and ethnic discrimination has emerged as a factor that may influence the experience of chronic pain in this population. Identifying modifiable psychosocial factors that influence the link between perceived discrimination and pain and that can be directly targeted in treatment is vital to reducing the disproportionate burden of CMP among Black individuals. The present study examines the moderating role of five risk factors (i.e., pain avoidance, pain fusion, experiential avoidance, pain catastrophizing, and pain anxiety) on the relationship between perceived discrimination and pain outcomes (i.e., pain intensity and interference) in a sample of 401 Black adults with CMP. We recruited 401 Black individuals (Mage = 35.98, 51.9% female) with self-reported CMP and assessed their self-reported perceived discrimination, pain intensity, pain interference, and pain-related psychosocial risk factors. Results indicated that higher scores on each of the psychosocial risk factors (i.e., pain avoidance, pain fusion, experiential avoidance, pain catastrophizing, and pain anxiety) were significantly associated with greater pain intensity and pain interference (all ps < 0.01). Further, pain avoidance (B = 0.12, p = .006), pain fusion (B = 0.13, p = .002), and pain anxiety (B = 0.13, p = .002) each significantly moderated the relation between perceived discrimination and pain intensity. Greater perceived discrimination was associated with greater pain intensity at higher levels of avoidance and fusion, and was associated with less pain intensity at lower levels of avoidance and pain anxiety. In interaction models predicting pain interference, both pain fusion (B = 0.14, p = .001) and pain anxiety (B = 0.10, p = .01) significantly moderated the relation between perceived discrimination and pain interference. Perceived discrimination was associated with greater pain interference at higher levels of pain fusion and pain anxiety, and was not associated with pain interference at lower levels of pain fusion and pain anxiety. The present findings provide important insights into psychosocial risk factors that moderate the link between perceived discrimination and pain outcomes, providing important clinical implications for the treatment of Black adults with chronic musculoskeletal pain.

A Tale of Two Treatments: A Randomised Controlled Trial of Mindfulness or Cognitive Behaviour Therapy Delivered Online for People with Rheumatoid Arthritis

INTRODUCTION

This study aimed to determine the relative efficacy of mindfulness-based stress reduction (MBSR) or cognitive behaviour therapy (CBT) in comparison to a waitlist control (WLC) for people with rheumatoid arthritis (RA). Participants completed assessments before and after treatment and at 6-month follow-up.

METHODS

Two hundred and sixty-nine participants with RA were recruited and randomised in a 2:2:1 ratio to MBSR:CBT:WLC. Participants completed a semi-structured clinical interview for depression and were stratified for history of recurrent depression. We measured the primary outcome of pain interference, as well as pain severity, depression, anxiety, functional ability, and fear of progression. We predicted that MBSR and CBT would result in improvements compared to WLC. We also predicted that those with a history of recurrent depression would benefit more from MBSR than CBT for depression.

RESULTS

MBSR and CBT were equally efficacious in reducing pain interference compared to WLC. Similar results were found for depression. MBSR demonstrated superior outcomes to CBT for fear of progression at post-treatment and functional ability at 6-month follow-up. CBT only was better than WLC for pain severity at 6-month follow-up. Depressive status did not moderate the efficacy of treatment.

CONCLUSIONS

MBSR and CBT resulted in statistically and clinically significant changes in pain interference compared to WLC. MBSR was more efficacious than CBT for functional ability and fear of progression, while CBT showed superiority for pain severity. The effect sizes were comparable to those achieved with face-to-face interventions, confirming both online treatments are effective for people with RA.

Benefits of Remote-Based Mindfulness on Physical Symptom Outcomes in Cancer Survivors: Systematic Review and Meta-Analysis

Background

Many cancer survivors experience a wide range of symptoms closely linked to psychological problems, highlighting the need for psychological treatment, one of the most popular being mindfulness. The use of the internet has greatly increased in the last decade, and has encouraged the use of remote-based interventions to help people living with cancer access treatment remotely via devices.

Objective

The primary aim of this study was to explore the efficacy of internet-based mindfulness interventions on the physical symptoms of people living with cancer, where physical symptoms are defined as distressing somatic experiences (eg fatigue, insomnia, and pain) regardless of the underlying cause. The secondary aim was to investigate interventions for the quality of life (QoL).

Methods

This study followed the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. Relevant articles were systematically searched using electronic databases, namely Scopus, Medline through PubMed, Cumulated Index in Nursing and Allied Health Literature (CINAHL) through EBSCOhost, and Cochrane Central Database. Randomized controlled and pilot trials involving adults and/or older adults with cancer and using remote-based mindfulness interventions compared to usual care were included. The quality of the trials included in this study was assessed using the revised Cochrane risk of bias, version 2.0. This study estimated the standardized mean difference (SMD) and mean difference (MD) with 95% CI. The I2 test was used to identify potential causes of heterogeneity. Publication bias was assessed using contour-enhanced funnel plots and the Egger linear regression test to reveal a small study effect.

Results

The initial search yielded 1985 records, of which 13 studies were ultimately included. After treatment, remote-based mindfulness significantly reduced fatigue (SMD -0.94; 95% CI: -1.56 to -0.33; P=.002), sleep disturbance (SMD -0.36; 95% CI: -0.60 to -0.12; P=.004), and improved physical function (SMD .25; 95% CI: 0.09 to 0.41; P=.002) compared to that observed before treatment. However, compared with usual care, remote-based mindfulness showed a statistically significant reduction only in sleep disturbance (SMD: -0.37; 95% CI: -0.58 to -0.16; P=.0006) after treatment. Moreover, remote-based mindfulness was not statistically significant in reducing pain both within and between groups.

Conclusions

Remote-based mindfulness shows promise in reducing sleep disturbances; however, its impact on fatigue, pain, and physical function may be limited.

Pain beliefs and their relationship with pain, psychological distress and catastrophizing in individuals with Parkinson's disease

In Parkinson's disease (PD), a large number of individuals are confronted with pain. This issue has been receiving increasing attention in literature in recent years, as the complexity of pain in this disease makes its evaluation and treatment challenging. However, psychological variables related to the pain experience have received limited attention, especially when it comes to the exploration of beliefs regarding pain which, to our knowledge, remains unexplored in PD. Pain beliefs are defined as a subset of a patient's belief system which represents a personal understanding of the pain experience. Four dimensions of pain beliefs have been isolated in literature: mystery, pain permanence, pain constancy and self-blame. Thus, the goal of this study was first to describe pain beliefs in individuals with PD and second, to explore the relationships between pain beliefs and clinical and psychological variables. One hundred and sixty-nine international individuals with PD completed an online survey with socio-demographic and medical data. Participants completed self-report instruments to assess their pain (King's Parkinson's Disease Pain Questionnaire, McGill Pain Questionnaire and Brief Pain Inventory), psychological distress (Beck Depression Inventory, short-form and Parkinson Anxiety Scale), pain catastrophizing (Pain Catastrophizing Scale) and pain beliefs catastrophizing (Pain Beliefs and Perception Inventory). The study's findings revealed that most participants' beliefs are marked by the dimension of permanence, suggesting that individuals with PD perceive the pain experience as chronic and enduring. Meanwhile, pain is minimally perceived as constant, mysterious, or a source of guilt. Our finding concerning the permanence dimension deserves specific attention: even though this belief is prevalent in our population, it is not, or only weakly, associated with an impact on mood or pain catastrophizing. These results bring forth several hypotheses for understanding, highlighting the role of acceptance, and offer new perspectives toward improving clinical practices in terms of assessing and managing pain in PD.

The effect of peer group management intervention on chronic pain intensity, number of areas of pain, and pain self-efficacy

OBJECTIVES

Chronic pain causes loss of workability, and pharmacological treatment is often not sufficient, whereas psychosocial treatments may relieve continual pain. This study aimed to investigate the effect of peer group management intervention among patients with chronic pain.

METHODS

The participants were 18-65-year-old employees of the Municipality of Helsinki (women 83%) who visited an occupational health care physician, nurse, psychologist, or physiotherapist for chronic pain lasting at least 3 months. An additional inclusion criterion was an elevated risk of work disability. Our study was a stepped wedge cluster, randomized controlled trial, and group interventions used mindfulness, relaxation, cognitive behavioral therapy, and acceptance and commitment therapy. We randomized sixty participants to either a pain management group intervention or to a waiting list with the same intervention 5 months later. After dropouts, 48 employees participated in 6 weekly group meetings. We followed up participants from groups A, B, and C for 12 months and groups D, E, and F for 6 months. As outcome measures, we used the pain Self-Efficacy Questionnaire, the number of areas of pain, the visual analog scale of pain, and the pain self-efficacy. We adjusted the results before and after the intervention for panel data, clustering effect, and time interval.

RESULTS

The peer group intervention decreased the number of areas of pain by 40%, from 5.96 (1-10) to 3.58 (p < 0.001), and increased the pain self-efficacy by 15%, from 30.4 to 37.5 (p < 0.001). Pain intensity decreased slightly, but not statistically significantly, from 7.1 to 6.8.

CONCLUSIONS

Peer group intervention for 6 weeks among municipal employees with chronic pain is partially effective. The number of areas of pain and pain self-efficacy were more sensitive indicators of change than the pain intensity. Any primary care unit with sufficient resources may implement the intervention.

Pain Catastrophizing and Substance Misuse: A Scoping Review of the Literature

BACKGROUND

Pain catastrophizing, or the interpretation of pain as unbearable or intolerable, can increase pain-related anxiety and severity. High levels of pain catastrophizing have also been linked to substance use, particularly for substances with analgesic properties. Importantly, behavioral treatments can reduce pain catastrophizing, making them promising interventions for mitigating pain-related substance use. The aim of this scoping review is to summarize literature investigating the relationship between pain catastrophizing and substance use in adults.

METHODS

We performed a scoping review of peer-reviewed literature. Included articles had both a measurement of pain catastrophizing and substance use, and reported analyses characterizing the relationship between the two.

RESULTS

Of the 341 abstracts identified, 47 articles met eligibility criteria. Most studies focused on people with chronic pain. Some studies also considered samples with substance use disorders (with and without chronic pain) or acute pain, and general population samples. There was generally a positive association between pain catastrophizing and substance misuse; this association was consistent across multiple samples and substances. Most studies were cross-sectional, although associations were also detected in longitudinal studies. The magnitude of associations tended to be stronger for higher severity substance use and more proximal tests of association. More longitudinal and experimental studies are needed, however, to better delineate these effects.

DISCUSSION

Findings indicate a consistent positive association between pain catastrophizing and substance use, highlighting the potential for interventions targeting pain catastrophizing to reduce negative substance-related consequences.

How Bud Craig's Insights Reshape the Research on Pain and Mind-Body Therapies

With his elegant studies, Bud Craig determined the structural neural basis for interoception and critically expanded our conceptual understanding of it. Importantly, he placed pain in the framework of interoception and redefined pain as a homeostatic emotion. Craig understood emotions and pain as experiences based on inferential brain processes within the theoretical model of prediction processing. This chapter aims to give a brief overview of relevant research. Mind-body therapies, such as meditation, mindfulness, yoga, Tai Chi, and others, are included as first-line non-pharmacological approaches in clinical guidelines for the management of chronic pain. Craig's groundbreaking work provided the background for our contemporary understanding of mind-body therapies and for the key role that interoceptive processes play in these therapies as they apply to a wide range of clinical conditions, including pain. This chapter reviews the tremendous influence that Craig's work had on the current state of research on mind-body therapies for managing chronic pain and how it led to new directions for cutting-edge clinical and neuroscientific research.

Development of a mindfulness-based intervention for narcolepsy: a feasibility study

STUDY OBJECTIVES

Mindfulness-based interventions (MBI) have been shown to improve psychosocial functioning in medical populations but have not been studied in narcolepsy. This study examined the feasibility and acceptability of an MBI that was adapted for narcolepsy, including three variations in program length.

METHODS

Adults with narcolepsy (N = 60) were randomized to MBI groups of varying durations: brief (4 weeks), standard (8 weeks), or extended (12 weeks). Participants completed assessments at baseline, 4, 8, and 12 weeks. To assess feasibility and acceptability, primary outcomes included attendance, meditation practice, and data completeness. Additionally, participants completed measures of mindfulness, self-compassion, mood, sleep, psychosocial functioning, and cognition. An effect size of Cohen's d ≥ 0.5 was used as the prespecified benchmark for a minimal clinically important difference (MCID).

RESULTS

The attendance, meditation, and data completeness benchmarks were met by 71.7%, 61.7%, and 78.3% of participants, respectively. Higher proportions of the brief and extended groups met these benchmarks compared to the standard group. All groups met the MCID for mindfulness, self-compassion, self-efficacy for managing emotions, positive psychosocial impact, global mental health, and fatigue. Standard and extended groups met the MCID for anxiety and depression, and extended groups met the MCID for additional measures including social and cognitive functioning, daytime sleepiness, hypersomnia symptoms, and hypersomnia-related functioning.

CONCLUSIONS

Results suggest that the remote delivery and data collection methods are feasible to employ in future clinical trials, and it appears that the extended MBI provides the most favorable clinical impact while maintaining attendance and engagement in meditation practice.

Virtual Reality for Subacute Pain After Orthopedic Traumatic Musculoskeletal Injuries: A Mixed Methods Pilot Study

OBJECTIVES

Acute orthopedic traumatic musculoskeletal injuries are prevalent, costly, and often lead to persistent pain and functional limitations. Psychological risk factors (eg, pain catastrophizing and anxiety) exacerbate these outcomes but are often overlooked in acute orthopedic care. Addressing gaps in current treatment approaches, this mixed-methods pilot study explored the use of a therapeutic virtual reality (VR; RelieVRx ), integrating principles of mindfulness and cognitive-behavioral therapy, for pain self-management at home following orthopedic injury.

METHODS

We enrolled 10 adults with acute orthopedic injuries and elevated pain catastrophizing or pain anxiety from Level 1 Trauma Clinics within the Mass General Brigham health care system. Participants completed daily RelieVRx sessions at home for 8 weeks, which included pain education, relaxation, mindfulness, games, and dynamic breathing biofeedback. Primary outcomes were a priori feasibility, appropriateness, acceptability, satisfaction, and safety. Secondary outcomes were pre-post measures of pain, physical function, sleep, depression, and hypothesized mechanisms (pain self-efficacy, mindfulness, and coping).

RESULTS

The VR and study procedures met or exceeded all benchmarks. We observed preliminary improvements in pain, physical functioning, sleep, depression, and mechanisms. Qualitative exit interviews confirmed high satisfaction with RelieVRx and yielded recommendations for promoting VR-based trials with orthopedic patients.

DISCUSSION

The results support a larger randomized clinical trial of RelieVRx versus a sham placebo control to replicate the findings and explore mechanisms. There is potential for self-guided VR to promote evidence-based pain management strategies and address the critical mental health care gap for patients following acute orthopedic injuries.

The Power of Thought: The Role of Psychological Attentiveness and Emotional Support in Patient Trajectories

In modern healthcare, the influence of a patient's mindset on health outcomes is an often neglected yet vital component of holistic care. This review explores the significant impact of positive and negative mindsets on disease progression and recovery, emphasizing the need to integrate mental wellness practices into conventional medical care. Drawing from a wide array of studies, it demonstrates how fostering a positive mindset can enhance patient trajectories across various medical specialties. The article advocates for training healthcare providers to adopt a more empathetic and patient-centered approach, bridging the gap between mind and body. By presenting compelling evidence on the correlation between patient mindset and health outcomes, this review highlights the potential benefits of incorporating psychological support and holistic strategies into standard care protocols. Practical strategies for implementing mindset-focused interventions are also proposed, including training programs for healthcare professionals and the development of interdisciplinary treatment plans. Ultimately, this article underscores the need for a paradigm shift in medical practice, advocating for a comprehensive approach that recognizes the power of thought in promoting patient wellness.

Outcome Expectancies, Effects, and Mechanisms of Brief Training in Mindfulness Meditation vs. Loving-Kindness Meditation vs a Control Condition for Pain Management: A Randomized Pilot Study

This study investigated the analgesic effects of a single session of mindfulness meditation (MM) and loving-kindness meditation (LKM) relative to a control. A total of 100 adults with chronic or current problematic pain completed a survey and were randomized to a 20-minute MM, LKM, or audiobook control. Co-primary outcomes of pain intensity and unpleasantness and mediators of mindfulness and self-compassion were assessed pre- and posttraining. Expectancies were assessed pretraining. Pain type (chronic vs current problematic) was a covariate. Relative to the control, higher expectancies were reported for MM and LKM (P < .001). MM (d = 0.41, P = .032) and LKM (d = 0.38, P = .027) had medium effects on pain intensity, with greater decreases than control (d = 0.05, P = .768). All conditions had small effects on unpleasantness. Mindful observing increased more within MM (d = 0.52, P = .022) and the control (d = 0.50, P = .011) than LKM (d = 0.12, P = .50); self-compassion increased more in LKM (d = 0.36, P = .042) than MM (d = 0.27, P = .201) and the control (d = 0.22, P = .249). The mediation models were nonsignificant. Pain type was a nonsignificant covariate. Overall, MM and LKM were associated with positive expectancies and small-medium pain intensity reductions, which did not differ by pain type. Although MM and LKM were associated with changes in theorized mediators, these changes did not underlie improvement.

Utilizing a learning health system to capture real-world patient data: Application of the reliable change index to evaluate and improve the outcome of a pain rehabilitation program

BACKGROUND AND OBJECTIVES

The learning healthcare system (LHS) has been developed to integrate patients' clinical data into clinical decisions and improve treatment outcomes. Having little guidance on this integration process, we aim to explain (a) an applicable analytic tool for clinicians to evaluate the clinical outcomes at a group and an individual level and (b) our quality improvement (QI) project, analyzing the outcomes of a new outpatient pain rehabilitation program ("Back-in-Action": BIA) and applying the analysis results to modify our clinical practice.

METHODS

Through our LHS (CHOIR; https://choir.stanford.edu), we administered the Pain Catastrophizing Scale (PCS), Chronic Pain Acceptance Questionnaire (CPAQ), and Patient-Reported Outcomes Measures (PROMIS)® before and after BIA. After searching for appropriate analytic tools, we decided to use the Reliable Change Index (RCI) to determine if an observed change in the direction of better (improvement) or worse (deterioration) would be beyond or within the measurement error (no change).

RESULTS

Our RCI calculations revealed that at least a 9-point decrease in the PCS scores and 10-point increase in the CPAQ scores would indicate reliable improvement. RCIs for the PROMIS measures ranged from 5 to 8 T-score points (i.e., 0.5-0.8 SD). When evaluating change scores of the PCS, CPAQ, and PROMIS measures, we found that 94% of patients showed improvement in at least one domain after BIA and 6% showed no reliable improvement.

CONCLUSIONS

Our QI project revealed RCI as a useful tool to evaluate treatment outcomes at a group and an individual level, and RCI could be incorporated into the LHS to generate a progress report automatically for clinicians. We further explained how clinicians could use RCI results to modify a clinical practice, to improve the outcomes of a pain program, and to develop individualized care plans. Lastly, we suggested future research areas to improve the LHS application in pain practice.

Pain Self-Efficacy Can Improve During a Visit With an Orthopedic Surgeon

BACKGROUND

Greater pain self-efficacy (PSE) is associated with reduced pain, fewer limitations, and increased quality of life after treatment for orthopedic conditions. The aims of this study were to (1) assess if PSE improves during a visit with an orthopedic surgeon and (2) identify modifiable visit factors that are associated with an increase in PSE.

MATERIALS AND METHODS

We performed a prospective observational study of orthopedic clinic visits at a multispecialty clinic from February to May 2022. New patients who presented to one of six orthopedic surgeons were approached for the study. Patients who provided consent completed a pre-visit questionnaire including the Pain Self-Efficacy Questionnaire (PSEQ) and demographic questions. A trained research member recorded the five-item Observing Patient Involvement in Decision Making Instrument (OPTION-5) score, number of questions asked, and visit duration. Immediately after the visit, patients completed a post-visit questionnaire consisting of the PSEQ and Perceived Involvement in Care Scale (PICS).

RESULTS

Of 132 patients enrolled, 61 (46%) had improved PSE after the orthopedic visit, with 38 (29%) having improvement above a clinically significant threshold. There were no significant differences between patients with increased PSE and those without increased PSE when comparing the PICS, OPTION-5, questions asked, or visit duration.

CONCLUSION

Almost half of the patients had improvement in PSE during an orthopedic visit. The causal pathway to how to improve PSE and the durability of the improved PSE have implications in strategies to improve patient outcomes in orthopedic surgery, such as communication methods and shared decision-making. Future research can focus on studying different interventions that facilitate improving PSE. [Orthopedics. 2024;47(4):e197-e203.].

Changes in mindfulness facets across yoga, CBT and stress education in individuals with generalized anxiety disorder

Improving mindfulness is an important treatment target for generalized anxiety disorder (GAD). However, less is known about how different treatments impact specific aspects of mindfulness. In a clinical trial (Simon et al., 2021), 226 individuals with GAD were randomized to 12 weeks of Kundalini Yoga (KY), cognitive behavioral therapy (CBT) or stress education (SE). To examine whether specific facets of mindfulness, as measured by the Five Facet Mindfulness Questionnaire (FFMQ) change more than others across treatment and between treatments, we ran a multi-variate multilevel growth curve model (MMLM). Results indicated that while the Non-judge, Act with Awareness, and Non-react facets increased significantly during treatment, the Observe and Describe facets did not. Improvement in the Acting with Awareness facet during treatment was significantly greater for KY than CBT. These findings reveal the need to better understand how behavioral treatments can influence specific components of mindfulness for those with anxiety.

Graph modeling of relational structures among functioning variables with low back pain: an exploratory analysis based on International Classification of Functioning, Disability and Health

BACKGROUND

Given the complex etiology, multidimensional impact, and widespread prevalence of low back pain (LBP), it is crucial to prioritize intervention targets based on understanding the relationships between functional impairments in patients. This prioritization maximizes the physical and psychological benefits for patients, and graph modeling holds promise in achieving these objectives.

AIM

The aim of this study was establishing a graphical model of functioning variables for LBP based on the International Classification of Functioning, Disability, and Health (ICF) to identify the most influential items (i.e., functioning variables) on the physical and mental well-being of patients. Exploring feasible intervention measures by understanding the dysfunction correlations among these variables.

DESIGN

Cross-sectional survey.

SETTING

Nine hospitals in Jiangsu Province, China.

POPULATION

Three hundred and six persons with LBP aged ≥18 years.

METHODS

All patients were assessed using the Comprehensive ICF Core Sets for LBP. The scoring system was converted to dichotomous data, with 1 indicating dysfunction and 0 indicating no dysfunction. In the graphical model, network parameters and the results of Item Response Theory modeling (as detailed in our other article) were used to determine the importance of items, while partial correlations were utilized to estimate the dysfunction correlations between functioning variables.

RESULTS

1) A total of 56 ICF items were located in the backbone structure of LBP, among which d430 (Lifting and carrying objects) occupied the most central position, followed by b126 (Temperament and personality functions). 2) In the main component of backbone structure, d430 has moderate dysfunction correlation with looking after one's health (0.6027), social norms, practices and ideologies (0.597), stability of joint functions (0.5759), and emotional functions (0.4078). b126 has moderate dysfunction correlation with basic interpersonal interactions (0.6595).

CONCLUSIONS

d430 and b126 significantly impact the physical and mental well-being of LBP patients. To improve d430, maintaining exercise habits, reducing working hours, enhancing lumbar stability, and overcoming fear-related emotions are recommended. Similarly, improving b126 can be achieved through enhancing interpersonal relationships.

CLINICAL REHABILITATION IMPACT

Through the identification of crucial functioning variables and the associated dysfunctional correlation relationships, graphical model of Comprehensive ICF Core Set for LBP can offer healthcare decision-makers valuable insights into potential treatment targets and pathways aimed at improving the condition of LBP patients.

Pain Catastrophizing: How Far Have We Come

The perception of pain is strongly influenced by various social, emotional, and cognitive factors. A psychological variable which has consistently been shown to exert its influence on pain is a cognitive process referred to as pain catastrophizing. Numerous studies have found it to be a strong predictor of pain intensity and disability across different clinical populations. It signifies a maladaptive response to pain marked by an exaggerated negative assessment, magnification of symptoms related to pain, and, in general, a tendency to experience marked pain-related worry, as well as experiencing feelings of helplessness when it comes to dealing with pain. Pain catastrophizing has been correlated to many adverse pain-related outcomes, including poor treatment response, unsatisfactory quality of life, and high disability related to both acute and chronic pain. Furthermore, there has been consistent evidence in support of a correlation between pain catastrophizing and mental health disorders, such as anxiety and depression. In this review, we aim to provide a comprehensive overview of the current state of knowledge regarding pain catastrophizing, with special emphasis on its clinical significance, and emerging treatment modalities which target it.

Understanding the Role of Therapist Quality in Accounting for Heterogeneity of Patient Outcomes in Psychosocial Chronic Pain Treatments

A variety of evidence-based psychosocial treatments now exist for chronic pain. However, on average, effect sizes have tended to be modest and there is a high degree of heterogeneity in treatment response. In this focus article, we explore the potential role that therapist quality in delivering treatment may have in accounting for a degree of this variability in outcome. Therapist quality refers to the skillful delivery of treatment, harnessing both specific and common therapeutic factors during sessions. While recognized as important to assess and report in clinical trials by some reporting guidelines, few randomized controlled trials evaluating psychosocial treatments for chronic pain have reported on therapist factors. We reviewed the clinical trials included in three systematic reviews and meta-analyses of trials of cognitive-behavioral therapy (mainly), mindfulness-based interventions, and acceptance and commitment therapy. We found that of the 134 trials included, only nine assessed and reported therapist quality indicators, with a variety of procedures used. This is concerning as without knowledge of the quality in which treatments are delivered, the estimates of effect sizes reported may be misrepresented. We contextualize this finding by drawing on the broader psychotherapy literature which has shown that more skillful, effective therapists demonstrated ten times better patient response rates. Examination of the characteristics associated with these more effective therapists tends to indicate that skillful engagement of common factors in therapy sessions represents a distinguishing feature. We conclude by providing recommendations for assessing and reporting on therapist quality within clinical trials evaluating psychosocial treatments for chronic pain. PERSPECTIVE: Therapist quality in the delivery of psychosocial treatments for chronic pain has rarely been assessed in clinical trials. We propose that therapist quality indicators are an under-studied mechanism that potentially contributes to the heterogeneity of treatment outcomes. We provide recommendations for assessing and reporting on therapist quality in future trials.

Culturally Adapting Mind-Body Interventions for Black Individuals with Chronic Pain: Arguments and Recommendations Towards a Task-Sharing Approach

Compared to non-Hispanic White individuals, non-Hispanic Black Individuals report worse chronic pain from a variety of medical issues. Among the options for non-pharmacological pain treatment, mind-body interventions (MBI) are a promising modality to help Black individuals manage their chronic pain effectively. MBIs such as mindfulness meditation improve chronic pain and chronic pain-related outcomes by shifting the individual's perception of pain away from stress-related cognitive appraisals, emotional reactions, and behaviors. MBIs may also address disparities in chronic pain outcomes between Black and White individuals because of their contextual overlap with (1) centering and contemplative prayer, (2) racial empowerment, and (3) social support. Despite this overlap, the demand for MBIs among Black individuals has generally been low due to lingering access and acceptability barriers. To reduce these barriers for Black individuals with chronic pain, we must adopt a community-engaged approach and culturally adapt MBIs for the specific historic, environmental, financial, and psychosocial needs of Black individuals. Example adaptations include increasing Black representation among MBI instructors, reducing geographical access barriers, accommodating the financial and personal realities of Black adults, and explicitly allowing relevant attitudes, practices, and terms.

Mindfulness intervention effect on endometriosis-related pain dimensions and its mediator role on stress and vitality: a path analysis approach

Endometriosis-related pain is supposedly mainly responsible for generating psychological stress and deteriorating the quality of life. However, the interaction between these factors has not been investigated, considering its multidimensional nature and through the path of effects of psychosocial approaches. The present study aims to investigate the effect of a brief mindfulness-based intervention (bMBI) on pain dimensions and its mediator role on psychological stress and QoL-Vitality improvement. A secondary analysis of a pilot randomized controlled trial using a series of parallel and serial mediators was carried out. The results showed that bMBI improves the sensory (B = -6.09 [-9.81, -2.52], β = -0.42) and affective (B = -3.40 [-5.02, -1.80], β = -0.47) pain. The bMBI effect on psychological stress reduction was mediated by these changes in sensory (B = -2.81 [-6.06, -0.41], β = -0.21) and affective (B = -1.97 [-5.07, -0.17], β = -0.15) pain. Serial sensory pain and psychological stress reduction (B = 2.27 [0.11, 5.81], β = -0.09) mediated the bMBI effect on quality of life vitality. Meditation training promotes additional improvement in affective and sensory pain characteristics through which psychological stress is reduced. The sensory pain dimension must be positively impacted in combination with psychological stress for the bMBI improves women's vitality. Adding a psychosocial intervention like meditation training to the standard treatment plan may be required for some women to achieve the needed changes to restore well-being.

Race-Based Differences in the Response to a Mindfulness Based Integrative Medical Group Visit Intervention for Chronic Pain

Background

Chronic pain is one of the most common drivers of healthcare utilization and a marked domain for health disparities, as African American/Black populations experience high rates of chronic pain. Integrative Medical Group Visits (IMGV) combine mindfulness techniques, evidence-based integrative medicine, and medical group visits. In a parent randomized controlled trial, this approach was tested as an adjunct treatment in a diverse, medically underserved population with chronic pain and depression.

Objective

To determine race-based heterogeneity in the effects of a mindfulness based treatment for chronic pain.

Methods

This secondary analysis of the parent trial assessed heterogeneity of treatment effects along racialized identity in terms of primary patient-reported pain outcomes in a racially diverse sample suffering from chronic pain and depression. The analytic approach examined comorbidities and sociodemographics between racialized groups. RMANOVAs examined trajectories in pain outcomes (average pain, pain severity, and pain interference) over three timepoints (baseline, 9, and 21 weeks) between participants identifying as African American/Black (n = 90) vs White (n = 29) across both intervention and control conditions.

Results

At baseline, African American/Black participants had higher pain severity and had significantly different age, work status, and comorbidity profiles. RMANOVA models also identified significant race-based differences in the response to the parent IMGV intervention. There was reduced pain severity in African American/Black subjects in the IMGV condition from baseline to 9 weeks. This change was not observed in White participants over this time period. However, there was a reduction in pain severity in White participants over the subsequent interval from 9 to 21 week where IMGV had no significant effect in African American/Black subjects during this latter time period.

Conclusion

Interactions between pain and racialization require further investigation to understand how race-based heterogeneity in the response to integrative medicine treatments for chronic pain contribute to the broader landscape of health inequity.

Prevention of non-specific back pain through exercise and education: A systematic review and meta-analysis

BACKGROUND

Clinical practice guidelines stress the importance of prevention and treatment of non-specific back pain through exercise therapy. However, it has not yet been confirmed whether the combination of exercise plus education is more effective than such interventions taken separately.

OBJECTIVE

To determine if the combination of exercise plus education is more effective for the prevention of non-specific back pain than exercise or education alone.

METHOD

A systematic search of studies whose sample consisted of participants without non-specific back pain (primary prevention) and participants with non-specific back pain (secondary and tertiary prevention) was conducted in the following databases in March 2023: PubMed, Scopus, Web of Science and Medline.

RESULTS

A total of 16 articles were selected. Statistically significant results were found in the pain variable with SMD =-2.02 (95% CI =-2.71 to -1.33; p< 0.001), the disability variable with SMD =-1.14 (95% CI =-1.63 to -0.65; p< 0.001), and the kinesiophobia variable with SMD =-1.8 (95% CI =-2.54 to -1.05; p< 0.001).

CONCLUSION

Interventions that combine exercise and education seem to have a greater preventive effect on non-specific back pain, disability and kinesiophobia than those that include exercise or education in an isolated manner.

Empowered Relief, cognitive behavioral therapy, and health education for people with chronic pain: a comparison of outcomes at 6-month Follow-up for a randomized controlled trial

Introduction

We previously conducted a 3-arm randomized trial (263 adults with chronic low back pain) which compared group-based (1) single-session pain relief skills intervention (Empowered Relief; ER); (2) 8-session cognitive behavioral therapy (CBT) for chronic back pain; and (3) single-session health and back pain education class (HE). Results suggested non-inferiority of ER vs. CBT at 3 months post-treatment on an array of outcomes.

Methods

Here, we tested the durability of treatment effects at 6 months post-treatment. We examined group differences in primary and secondary outcomes at 6 months and the degree to which outcomes eroded or improved from 3-month to 6-month within each treatment group.

Results

Empowered Relief remained non-inferior to CBT on most outcomes, whereas both ER and CBT remained superior to HE on most outcomes. Outcome improvements within ER did not decrease significantly from 3-month to 6-month, and indeed ER showed additional 3- to 6-month improvements on pain catastrophizing, pain bothersomeness, and anxiety. Effects of ER at 6 months post-treatment (moderate term outcomes) kept pace with effects reported by participants who underwent 8-session CBT.

Conclusions

The maintenance of these absolute levels implies strong stability of ER effects. Results extend to 6 months post-treatment previous findings documenting that ER and CBT exhibit similarly potent effects on outcomes.

Home-Use and Portable Biofeedback Lowers Anxiety and Pain in Chronic Pain Subjects

In this study, we investigated the use of novel, home-use and portable biofeedback devices in a remote program for managing chronic pain. In three separate 4-week pilot studies, participants engaged in twice-daily, 10-minute biofeedback sessions, with self-assessed reductions in anxiety and pain levels using the 6-item State-Trait Anxiety Inventory (STAI-6) and Visual Analogue Scale (VAS), respectively, in Studies 2 and 3. Among these 113 (Study 2) and 237 (Study 3) biofeedback sessions, 81 (∼72%) and 130 (∼55%) showed reductions in pain, while 93 (∼82%) and 184 (∼78%) experienced reductions in anxiety. A positive relationship was found between anxiety and pain reduction, indicating that larger reductions in anxiety correspond to larger reductions in pain. In Study 1, only anxiety reductions were measured: across 143 biofeedback sessions, 127 experienced reductions in anxiety (∼89%). Participants in all studies demonstrated reductions in baseline to final results in pain, anxiety, and showed increases in satisfaction and recovery. Our results provide strong evidence that portable biofeedback devices can enhance pain management programs by helping to alleviate anxiety and pain in individuals living with chronic conditions. This study can provide a basis for the integration of biofeedback devices into the expanding research of lifestyle and integrative medicine.

Promising Subjective and Objective Benefits of Modified Mindfulness-Based Stress Reduction Training for Chinese Adults with Chronic Pain: A Pilot Randomized Control Study

INTRODUCTION

Mindfulness-based stress reduction (MBSR) has demonstrated its effectiveness in reducing pain-related stress in adults with chronic pain. However, the implementation of MBSR needs modifications across cultures. This pilot study reports the findings of a randomized controlled trial that investigated the effects of a culturally adaptive MBSR program on self-report and neuroimaging outcomes for chronic pain adults in China.

METHODS

Sixty-seven participants were randomly assigned to the treatment group (n = 40) or the treatment-as-usual group (n = 27) group at a ratio of 1.5:1. Participants completed self-report measures of pain severity, pain interference, depression, perceived stress, pain catastrophizing, mindfulness, and resilience at baseline assessment (T1), post-treatment (T2), and 3-month follow-up (T3) assessments. Functional magnetic resonance imaging (fMRI) scanning was also performed at T1 and T3 assessments.

RESULTS

For the intention-to-treat sample, the results of the mixed-effect model indicated that Group × Time interaction was significant for pain catastrophizing only (F (2, 130) = 3.51, p = 0.033). Compared with the control group, those in the MBSR group reported greater reductions in pain catastrophizing at T2 (d = - 0.60), though this effect was not maintained at T3 (d = - 0.05). Additionally, the results of completer analyses found significant Group × Time interactions for pain interference (F (2, 88) = 4.40, p = 0.015) and perceived stress (F (2, 88) = 3.13, p = 0.048), but not for other measures. Finally, both groups exhibited decreased regional homogeneity (ReHo) in the frontal lobe, while increased ReHo in the cerebellum anterior lobe was unique to the MBSR group.

CONCLUSIONS

The present findings suggest that the minor modified MBSR program improves certain pain-related outcomes for Chinese adults with chronic pain. Future studies with larger samples of Chinese chronic pain patients are needed to detect the small-to-moderate benefit of MBSR on fMRI and/or other objective methods.

Efficacy of cognitive behavioral therapy for reducing pain susceptibility and increasing social engagement in patients with chronic low back pain: A systematic review and meta-analysis

BACKGROUND

The objective of this study was to evaluate the efficacy of cognitive behavioral therapy in improving social engagement and pain susceptibility in patients with chronic low back pain (≥6 months duration).

METHODS

From the initial to January 2023, 5 databases were searched for randomized controlled trials, literature screening, quality evaluation, and data extraction were performed by 2 independent researchers throughout, Meta-analysis was performed using RevMan 5.4 software, standardized mean difference (SMD) was calculated for different indicators, and the combined experimental and control groups were calculated using random-effects models or fixed-effects models effect sizes, and forest plots were drawn to present the results.

RESULTS

A total of 16 studies containing 2527 patients with chronic nonspecific low back pain, all of whom had pain lasting longer than 6 months, were included, and after treatment, cognitive behavioral therapy (CBT) was superior to other treatments in improving social participation [SMD = -0.30, 95%CI (-0.60, -0.01), Z = 2.02, P = .04]. There was no significant difference from other treatments in improving patient depression [SMD = -0.07, 95%CI (-0.19, 0.05), Z = 1.11, P = .27] and anxiety [SMD = -0.07, 95%CI (-0.30, 0.16), Z = 0.52, P = .57]. Three papers describe the superiority of CBT over other treatments in improving sleep quality, but the metrics could not be combined due to too little literature.

CONCLUSION

CBT can improve patients' social participation and pain susceptibility to some extent, but it does not show advantages for managing negative emotions (depression, anxiety). Due to the limited number and low quality of included literature, the above findings still need to be validated by conducting a large sample of high-quality RCTs.

Cognitive-affective changes mediate the mindfulness-based intervention effect on endometriosis-related pain and mental health: A path analysis approach

BACKGROUND

There is poor knowledge about the therapeutic mechanisms of the conservative interventions for endometriosis. We hypothesized that the effects of a brief mindfulness-based intervention (bMBI) on pelvic pain intensity (PPI), pain unpleasantness (PU) and quality of life mental health (QoL-MH) are mediated by direct and indirect paths of changes in pain catastrophizing (PC), positive affect (PA) and negative affect (NA).

METHODS

A secondary analysis of a pilot randomized controlled trial of women with endometriosis, assigned to standard medical treatment (n = 32) and standard medical treatment plus bMBI (n = 31). We tested a series of parallel and serial mediators (PC, PA and NA) of the relationship between bMBI and outcomes (PPI, PU and QoL-MH).

RESULTS

The bMBI group demonstrated improvement in PA (Cohen's f2  = 0.12 [0.01, 0.36]), decreases in NA (Cohen's f2  = 0.06 [0.00, 0.24]) and PC (Cohen's f2  = 0.16 [0.02, 0.42]). The PC reduction mediated the effect of the bMBI on PPI and PU directly; however, the PC effect through PA increase mediated the PU marginally but not PPI changes. bMBI effect on Qol-MH was mediated directly by PA and NA. The PC improved Qol-MH through PA increase and Pain decrease but not via NA.

CONCLUSIONS

Our findings showed that bMBI impacts pain through changes in pain-related cognitive-affective factors. bMBI can improve QoL-MH by multiple pathways, including but not limited to pain reduction, highlighting the independent potential of improvement in affect to restore mental health in endometriosis.

SIGNIFICANCE

Brief mindfulness-based intervention improves endometriosis pain through pain-related cognitive-affective factors and quality of life mental health via pain and affect changes unrelated to pain.

Beyond biopsychosocial: The keystone mechanism theory of pain

Pain is a deeply personal experience, with interindividual differences in its chronification and treatment presenting a formidable healthcare challenge. The biopsychosocial model (BPSm) has been hugely influential within nascent attempts at precision pain medicine, steering the field away from a reductionist biomechanical viewpoint and emphasising complex interactions of biological, psychological, and social factors which shape the individuality of pain. However, despite offering a strong theoretical foundation and holistic perspective, we contend that the BPSm remains limited in its capacity to deliver truly mechanistically informed treatment of pain. We therefore propose the keystone model of pain which offers a pragmatic balance between the dimensionality expansive BPSm and overly reductive approaches, providing both theoretical and practical advantages for the transition from treating populations to individual people.

Towards a better Comprehension and Management of Pain and Psychological Distress in Parkinson's: The Role of Catastrophizing

OBJECTIVES

Pain is very prevalent in Parkinson's and challenging to manage. As many people with Parkinson's (PwP) with pain suffer from anxious and depressive symptoms, we examined the role of catastrophizing in mediating the relationship between pain and psychological distress for this population.

METHODS

169 international PwP completed an online survey with socio-demographic and medical data. Participants completed psychometric tests to assess their pain (King's Parkinson's Disease Pain Questionnaire, McGill Pain Questionnaire and Brief Pain Inventory), psychological distress (Beck Depression Inventory and Parkinson Anxiety Scale), pain coping strategies (Coping Strategies Questionnaire) and pain catastrophizing (Pain Catastrophizing Scale).

RESULTS

Depending on the tool used, 82.8% to 95.2% of participants reported pain. 23.5 % and 67.5% of participants showed respectively significant levels of depressive and anxiety symptoms. Psychological distress was significantly correlated with the quality of pain (both sensory and affective dimensions). Statistical models highlighted the mediating role of catastrophizing in the relationship between psychological distress and pain in Parkinson's.

CONCLUSION

These findings offer new perspectives toward understanding the underlying mechanisms of pain in Parkinson's and for effective therapeutic intervention goals to facilitate adaptation to pain symptoms in Parkinson's.

Self-compassion and pain disability in adults with chronic pain: The mediating role of future self-identification and self-efficacy

Pain disability is a primary target of treatment for chronic pain. Self-compassion shows promise as an intervention to reduce pain disability, but mechanisms linking self-compassion with less pain disability remain to be identified. This study examined two potential mechanisms, health self-efficacy and future self-identification (FSI), as parallel mediators of the relation between self-compassion and pain disability. Adults (N = 188; Mage = 40.34, SD = 11.53; 70.9% female) screened for chronic pain were recruited through online convenience sampling. Participants completed self-report measures of demographics, health status, and primary study variables. Self-compassion was positively associated with FSI and self-efficacy, but only self-efficacy was found to mediate the negative relation between self-compassion and pain disability, such that self-compassion was associated with higher self-efficacy, which was associated with less pain disability. Future experimental and longitudinal studies can establish whether the negative relation between self-compassion and pain disability is causal and mediated via health self-efficacy.

The Effectiveness of a Mindfulness-Based Intervention Integrated with Physical Therapy (MIND-PT) for Postsurgical Rehabilitation After Lumbar Surgery: A Protocol for a Randomized Controlled Trial as Part of the Back Pain Consortium (BACPAC) Research Program

BACKGROUND

Improving pain management for persons with chronic low back pain (LBP) undergoing surgery is an important consideration in improving patient-centered outcomes and reducing the risk of persistent opioid use after surgery. Nonpharmacological treatments, including physical therapy and mindfulness, are beneficial for nonsurgical LBP through complementary biopsychosocial mechanisms, but their integration and application for persons undergoing surgery for LBP have not been examined. This study (MIND-PT) is a multisite randomized trial that compares an enriched pain management (EPM) pathway that integrates physical therapy and mindfulness vs usual-care pain management (UC) for persons undergoing surgery for LBP.

DESIGN

Participants from military treatment facilities will be enrolled before surgery and individually randomized to the EPM or UC pain management pathways. Participants assigned to EPM will receive presurgical biopsychosocial education and mindfulness instruction. After surgery, the EPM group will receive 10 sessions of physical therapy with integrated mindfulness techniques. Participants assigned to the UC group will receive usual pain management care after surgery. The primary outcome will be the pain impact, assessed with the Pain, Enjoyment, and General Activity (PEG) scale. Time to opioid discontinuation is the main secondary outcome.

SUMMARY

This trial is part of the National Institutes of Health Helping to End Addiction Long-term (HEAL) initiative, which is focused on providing scientific solutions to the opioid crisis. The MIND-PT study will examine an innovative program combining nonpharmacological treatments designed to improve outcomes and reduce opioid overreliance in persons undergoing lumbar surgery.

Pain acceptance and psychological inflexibility predict pain interference outcomes for persons with chronic pain receiving pain psychology

OBJECTIVES

Awareness (being present), acceptance, and engagement (committed action) are three dimensions of psychological flexibility. Understanding these in the context of chronic pain may identify treatment targets to help refine individual treatment. Our objective was to test the predictive capacity of three dimensions within the psychological flexibility model on the longitudinal trajectory of pain interference.

METHODS

Patients receiving pain psychology treatment at a pain management center participated in this pragmatic clinical longitudinal study (n=86 with at least three assessments; Mean age=51 years; Gender=60 females, 26 males). Measures included the Five Facet Mindfulness Questionnaire (FFMQ-SF); Chronic Pain Acceptance Questionnaire (CPAQ-8); Psychological Inflexibility in Pain Scale (PIPS-12); and Committed Action Questionnaire (CAQ-8). The dependent variable was the Patient Reported Outcomes Information System (PROMIS) Pain Interference (PI). We used latent growth modelling to analyze scores assessed within 180 days of patient care.

RESULTS

Psychological inflexibility (PIPS-12) and pain acceptance (CPAQ-8) measured at baseline predicted PI outcomes (n=86). PIPS-12 showed a direct relationship with pain interference (PI), where higher PIPS-12 scores predicted significantly higher PI mean scores on average across the study period (ρ=0.422, r2=0.382) but also predicted significantly greater decreases in PI across time (ρ=-0.489, r2=0.123). Higher CPAQ-8 scores predicted significantly lower PI mean scores on average across the study period (ρ=-0.478, r2=0.453) but also significantly smaller decreases in PI across time (ρ=0.495, r2=0.076). Awareness (FFMQ-SF) and engagement (CAQ-8) were not predictive of PI outcomes.

CONCLUSIONS

Patients who entered pain psychology treatment with lower pain acceptance and higher psychological inflexibility showed the largest reductions in pain interference across time. These results contribute towards a novel prognostic understanding of the predictive roles of an enhancing dimension and limiting dimension of psychological flexibility.

Innovative treatment formats, technologies, and clinician trainings that improve access to behavioral pain treatment for youth and adults

Chronic pain is prevalent across the life span and associated with significant individual and societal costs. Behavioral interventions are recommended as the gold-standard, evidence-based interventions for chronic pain, but barriers, such as lack of pain-trained clinicians, poor insurance coverage, and high treatment burden, limit patients' ability to access evidenced-based pain education and treatment resources. Recent advances in technology offer new opportunities to leverage innovative digital formats to overcome these barriers and dramatically increase access to high-quality, evidenced-based pain treatments for youth and adults. This scoping review highlights new advances. First, we describe system-level barriers to the broad dissemination of behavioral pain treatment. Next, we review several promising new pediatric and adult pain education and treatment technology innovations to improve access and scalability of evidence-based behavioral pain treatments. Current challenges and future research and clinical recommendations are offered.

Effect of mindfulness-based mind-body therapies in patients with non-specific low back pain-A network meta-analysis of randomized controlled trials

Background/objectives

Although mindfulness-based mind-body therapy (MBMBT) is an effective non-surgical treatment for patients with non-specific low back pain (NLBP), the best MBMBT mode of treatment for NLBP patients has not been identified. Therefore, a network meta-analysis (NMA) was conducted to compare the effects of different MBMBTs in the treatment of NLBP patients.

Methods

PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and Web of Science databases were searched for randomized controlled trials (RCTs) applying MBMBT for the treatment of NLBP patients, with all of the searches ranging from the time of database creation to January 2023. After 2 researchers independently screened the literature, extracted information, and evaluated the risks of biases in the included studies, the data were analyzed by using Stata 16.0 software.

Results

A total of 46 RCTs were included, including 3,886 NLBP patients and 9 MBMBT (Yoga, Ayurvedic Massage, Pilates, Craniosacral Therapy, Meditation, Meditation + Yoga, Qigong, Tai Chi, and Dance). The results of the NMA showed that Craniosacral Therapy [surface under the cumulative ranking (SUCRA): 99.2 and 99.5%] ranked the highest in terms of improving pain and disability, followed by Other Manipulations (SUCRA: 80.6 and 90.8%) and Pilates (SUCRA: 54.5 and 71.2%). In terms of improving physical health, Craniosacral Therapy (SUCRA: 100%) ranked the highest, followed by Pilates (SUCRA: 72.3%) and Meditation (SUCRA: 55.9%). In terms of improving mental health, Craniosacral Therapy (SUCRA: 100%) ranked the highest, followed by Meditation (SUCRA: 70.7%) and Pilates (SUCRA: 63.2%). However, in terms of improving pain, physical health, and mental health, Usual Care (SUCRA: 7.0, 14.2, and 11.8%, respectively) ranked lowest. Moreover, in terms of improving disability, Dance (SUCRA: 11.3%) ranked lowest.

Conclusion

This NMA shows that Craniosacral Therapy may be the most effective MBMBT in treating NLBP patients and deserves to be promoted for clinical use.

Tri-process model of interpersonal mindfulness: theoretical framework and study protocol

According to the Center for Disease Control and Prevention, over 14% of the US population practice mindfulness meditation. The effects of mindfulness training on physical and mental health have been consistently documented, but its effects on interpersonal relationships are not yet fully understood or investigated. Interpersonal relationships play a crucial role in the wellbeing of individuals and society, and therefore, warrants further study. The aim of this paper is to present a tri-process theoretical model of interpersonal mindfulness and a study protocol to validate the proposed model. Specifically, according to the proposed model, mindfulness meditation training increases the self-awareness, self-regulation, and prosociality of those receiving the training, which ameliorates the quality of interpersonal interactions and the socioemotional support provided to other individuals. Finally, better socioemotional support increases the support receiver's ability to regulate their emotions. Using a multiphasic longitudinal design involving 640 participants randomized into 480 dyads, the proposed protocol aims to validate the tri-process model and to investigate its mechanisms of actions. The proposed study has important theoretical and social implications and will allow devising new and more effective interpersonal mindfulness programs with applications in multiple fields.

Intensity of Chronic Low Back Pain and Activity Interference: A Daily Diary Study of the Moderating Role of Cognitive Pain Coping Strategies

OBJECTIVE

Chronic low back pain (CLBP) has a significant negative impact on daily functioning, particularly for those with challenges coping adaptively with ongoing pain. However, the dynamics of pain coping in daily life remain understudied. Therefore, we examined the extent to which pain intensity interferes with daily activities, and assessed whether pain coping strategies (as assessed using daily diaries) moderated this link.

METHOD

We analyzed diary data from a sample of 84 participants with CLBP who completed daily diaries for up to 30 days rating pain intensity, pain interference with daily activities, and their use of pain coping strategies, including pain rumination (i.e., repetitive thinking about the pain and its causes), reappraisal (i.e., evaluating one's pain less negatively or more positively), and distraction (i.e., diverting attention from the pain). We hypothesized that these coping strategies would moderate the associations between pain and pain interference with daily activities, although in different directions.

RESULTS

Results suggest that pain rumination strengthens the association between pain intensity and pain interference both on the person and day level, while pain reappraisal and distraction weaken this association, at the day and person levels, respectively.

CONCLUSION

Our findings suggest that those who are more preoccupied with their pain and those who are less likely to reappraise their pain have more pain interference with daily activities. These findings build on prior work on pain coping by using daily diaries and highlight two pain coping strategies that have particular relevance for reducing the impact of CLBP in daily life.

Meditation Practice, Mindfulness, and Pain-Related Outcomes in Mindfulness-Based Treatment for Episodic Migraine

Objectives

Mindfulness-based interventions (MBIs) have emerged as promising prophylactic episodic migraine treatments. The present study investigated biopsychosocial predictors and outcomes associated with formal, daily-life meditation practice in migraine patients undergoing MBI, and whether augmented mindfulness mechanistically underlies change.

Methods

Secondary analyses of clinical trial data comparing a 12-week enhanced mindfulness-based stress reduction course (MBSR + ; n = 50) to stress management for headache (SMH; n = 48) were conducted.

Results

Pre-treatment mesocorticolimbic system functioning (i.e., greater resting state ventromedial prefrontal cortex-right nucleus accumbens [vmPFC-rNAC] functional connectivity) predicted greater meditation practice duration over MBSR + (r = 0.58, p = 0.001), as well as the change in headache frequency from pre- to post-treatment (B = -12.60, p = 0.02) such that MBSR + participants with greater vmPFC-rNAC connectivity showed greater reductions in headache frequency. MBSR + participants who meditated more showed greater increases in mindfulness (B = 0.52, p = 0.02) and reductions in the helplessness facet of pain catastrophizing (B = -0.13, p = 0.01), but not headache frequency, severity, or impact. Augmented mindfulness mediated reductions in headache impact resulting from MBSR + , but not headache frequency.

Conclusions

Mesocorticolimbic system function is implicated in motivated behavior, and thus, motivation-enhancing interventions might be delivered alongside mindfulness-based training to enhance meditation practice engagement. Formal, daily-life meditation practice duration appears to benefit pain-related cognitions, but not clinical pain, while mindfulness emerges as a mechanism of MBIs on headache impact, but not frequency. Further research is needed to investigate the day-to-day effects of formal, daily-life meditation practice on pain, and continue to characterize the specific mechanisms of MBIs on headache outcomes.

The group mechanism in treatment: group identification and cohesion contributes to reducing chronic lower back pain by increasing personal control

PURPOSE

There is increasing recognition of the contribution that group processes, particularly identification and cohesion, make to outcomes of group delivered health treatments. This study examined the role that these particular group processes play in the treatment of lower back pain, and a theorised mechanism of personal control through which group treatment might enhance outcomes.

METHODS

Participants (N = 85) elected to either receive NeuroHAB^®, a defined functional movement therapy of 8 weeks duration, or continue with treatment-as-usual (TAU). Pain intensity and disability were assessed at baseline (T1) and post-intervention or 8 weeks later (T2), as well as at a 1-month follow-up (T3). Only the NeuroHAB^® participants additionally completed weekly questionnaires that measured treatment group identification, cohesion, and personal control.

RESULTS

NeuroHAB^® was significantly more effective than TAU in reducing pain intensity and disability at T2 and T3. Furthermore, among NeuroHAB^® recipients, stronger treatment group identification and cohesion early in the program predicted better pain outcomes over time, and this relationship was fully mediated by perceptions of personal control.

CONCLUSION

These data provide further support for the role of group identification and cohesion as a contributing mechanism of change in group-based treatments and extend this to the domain of pain management.Implications for RehabilitationA focus on defined functional movement therapy, as offered by the NeuroHAB^® group program, was found to improve pain outcomes in patients with lower back pain.A key ingredient in the NeuroHAB^® rehabilitation program was its group delivery.Group delivery supported treatment group identification and cohesion which, through enhancing the perception of personal control, reduced pain intensity and disability.

Beyond the pain: A qualitative study exploring the physical therapy experience in patients with chronic low back pain

BACKGROUND

Chronic low back pain (cLBP) is a complex condition that is physically and psychologically debilitating, with vulnerable populations experiencing more severe outcomes. Physical therapy (PT) includes evidence-based treatments that can reduce disability, however the experience of PT can vary amongst different populations. Empirical evidence is largely based on majority samples that are predominantly white with high educational attainment. Little is known regarding how people from vulnerable groups (e.g. low income and racial minority) experience physical therapy treatment for low back pain.

OBJECTIVE

To describe the experience of physical therapy in a predominantly low-income and minority population with cLBP.

METHODS

This qualitative study was embedded within a randomized controlled trial for patients with cLBP in urban, underserved communities. We used a convenience sample to interview 12 participants from the 102 who participated in the PT arm of the trial and then performed thematic analysis to describe their experience.

RESULTS

Three major themes emerged: 1) Empowerment through education and exercise; 2) Interconnectedness to providers and other patients; and 3) Improvements in pain, body mechanics, and mood. Divergent cases were few however centered around a lack of improvement in pain or an absence of connection with the therapist. Within the first theme a prevailing sub-theme emerged that aligned with Bandura's theory of self-efficacy: 1) Mastery of experience; 2) Verbal persuasion; 3) Vicarious experience; and 4) Physiological state.

CONCLUSIONS

Our participants' insight highlighted the value of cognitive-emotional and interpersonal dimensions of PT. These may be particularly important components of PT in populations that have experienced systemic distrust in providers and disparities in services. Future work could use Bandura's model of self-efficacy to build a PT intervention comprised of fear-based movement exercises, interconnectedness, a strong therapeutic alliance, and mindfulness techniques.

Randomized controlled trial protocol of health coaching for veterans with complex chronic pain

BACKGROUND

Pain predominant multisymptom illness (pain-CMI) refers to symptom-based conditions where pain is a primary symptom. There is initial evidence that health coaching may be efficacious in treating pain-CMI because it can be tailored to the veteran's goals and emphasizes long-term behavior change, which may indirectly impact the maintaining factors of pain-CMI (e.g., catastrophizing, poor pain control, and limited activity). This paper describes the study protocol and rationale of a randomized controlled trial that will compare the efficacy of remote-delivered health coaching in reducing disability and pain impairment for veterans with pain-CMI to remote-delivered supportive psychotherapy.

METHODS

This randomized controlled trial will consist of two treatment arms: remote-delivered health coaching and remote-delivered supportive psychotherapy, the active control. Each treatment condition will consist of twelve, weekly one-on-one meetings with a study provider. In addition to the baseline assessment, participants will also complete 6-week (mid-treatment), 12-week (post-treatment), and 24-week (follow-up) assessments that consist of questionnaires that can be completed remotely. The primary aims for this study are to determine whether health coaching reduces disability and pain impairment as compared to supportive psychotherapy. We will also examine whether health coaching reduces physical symptoms, catastrophizing, limiting activity, and increasing pain control as compared to supportive psychotherapy.

DISCUSSION

This study will contribute to the existing literature on pain-CMI and report the effectiveness of a novel, remote-delivered behavioral intervention.

Distinct and shared therapeutic neural mechanisms of mindfulness-based and social support stress reduction groups in adults with autism spectrum disorder

BACKGROUND

Mindfulness-based stress reduction (MBSR) alleviates depression and anxiety in adults with autism spectrum disorder (ASD); however, underlying therapeutic neural mechanisms and mindfulness-specific effects have yet to be elucidated.

METHODS

We randomly assigned adults with ASD to MBSR or social support/education (SE). They completed questionnaires that assessed depression, anxiety, mindfulness traits, autistic traits and executive functioning abilities as well as a self-reflection functional MRI task. We used repeated-measures analysis of covariance (ANCOVA) to evaluate behavioural changes. To identify task-specific connectivity changes, we performed a generalized psychophysiological interactions (gPPI) functional connectivity (FC) analysis on regions of interest (ROIs; insula, amygdala, cingulum and prefrontal cortex [PFC]). We used Pearson correlations to explore brain-behaviour relationships.

RESULTS

Our final sample included 78 adults with ASD - 39 who received MBSR and 39 who received SE. Mindfulness-based stress reduction uniquely improved executive functioning abilities and increased mindfulness traits, whereas both MBSR and SE groups showed reductions in depression, anxiety and autistic traits. Decreases specific to MBSR in insula-thalamus FC were associated with anxiety reduction and increased mindfulness traits, including the trait "nonjudgment;" MBSR-specific decreases in PFC-posterior cingulate connectivity correlated with improved working memory. Both groups showed decreased amygdala-sensorimotor and medial-lateral PFC connectivity, which corresponded with reduced depression.

LIMITATIONS

Larger sample sizes and neuropsychological evaluations are needed to replicate and extend these findings.

CONCLUSION

Together, our findings suggest that MBSR and SE are similarly efficacious for depression, anxiety and autistic traits, whereas MBSR produced additional salutary effects related to executive functioning and mindfulness traits. Findings from gPPI identified shared and distinct therapeutic neural mechanisms, implicating the default mode and salience networks. Our results mark an early step toward the development of personalized medicine for psychiatric symptoms in ASD and offer novel neural targets for future neurostimulation research.

Blinding and sham control methods in trials of physical, psychological, and self-management interventions for pain (article I): a systematic review and description of methods

ABSTRACT

Blinding is challenging in randomised controlled trials of physical, psychological, and self-management therapies for pain, mainly because of their complex and participatory nature. To develop standards for the design, implementation, and reporting of control interventions in efficacy and mechanistic trials, a systematic overview of currently used sham interventions and other blinding methods was required. Twelve databases were searched for placebo or sham-controlled randomised clinical trials of physical, psychological, and self-management treatments in a clinical pain population. Screening and data extraction were performed in duplicate, and trial features, description of control methods, and their similarity to the active intervention under investigation were extracted (protocol registration ID: CRD42020206590). The review included 198 unique control interventions, published between 2008 and December 2021. Most trials studied people with chronic pain, and more than half were manual therapy trials. The described control interventions ranged from clearly modelled based on the active treatment to largely dissimilar control interventions. Similarity between control and active interventions was more frequent for certain aspects (eg, duration and frequency of treatments) than others (eg, physical treatment procedures and patient sensory experiences). We also provide an overview of additional, potentially useful methods to enhance blinding, as well as the reporting of processes involved in developing control interventions. A comprehensive picture of prevalent blinding methods is provided, including a detailed assessment of the resemblance between active and control interventions. These findings can inform future developments of control interventions in efficacy and mechanistic trials and best-practice recommendations.
