Acceptance- and mindfulness-based interventions for the treatment of chronic pain: a meta-analytic review

Coping strategies among individuals with multiple physical symptoms: A general population-based cross-sectional study

OBJECTIVE

Coping has been suggested as a perpetuating factor for physical symptoms. The aim of this study was to examine the use of the coping strategies approach, resignation, and diversion in individuals with multiple physical symptoms according to the construct of Bodily Distress Syndrome (BDS).

METHODS

This cross-sectional study was part of the nationwide web-based survey Danish Symptom Cohort (DaSC). In total, 100,000 individuals were invited to participate, and individuals eligible for the present study were respondents aged 20-64 years without a current or recent pregnancy. Multiple physical symptoms were identified using the BDS checklist, and coping was assessed by the Brief Approach/Avoidance Coping Questionnaire. Statistical analyses included descriptive statistics and multinomial and logistic regression.

RESULTS

A total of 35,810 respondents were included in the study, of which 8512 (23.8%) fulfilled the criteria for having multiple physical symptoms. This group of respondents had lower coping scores on approach and higher coping scores on resignation and diversion compared with the non-BDS group. The regression analyses showed that high scores on approach were associated with a lower probability of having multiple symptoms (adjusted OR 0.92, 95% CI: 0.91-0.92), whereas high scores on diversion and resignation were associated with a higher probability of having multiple symptoms (adjusted OR 1.10; 95% CI: 1.09-1.11 and adjusted OR 1.19; 95% CI: 1.18-1.20, respectively).

CONCLUSION

The study supports the hypothesis that experiencing multiple physical symptoms is associated with certain coping strategies. This is relevant knowledge for health care professionals who will be treating this patient group.

Psychological management of patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS): a systematic review

OBJECTIVES

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a complex condition. Despite recommendations for the inclusion of non-pharmacological treatment in the management of CP/CPPS, the focus has predominantly been on the inclusion of physical therapies with minimal discussion of psychological interventions. Therefore, this systematic review aimed to evaluate peer-reviewed studies of psychological interventions for men with CP/CPPS to determine their therapeutic efficacy and quality of intervention.

METHODS

The review was registered in PROSPERO and based on PRISMA 2020 protocol. The systematic literature search was conducted in six databases. Quantitative studies of psychological intervention for adult men with CP/CPPS that provided outcome measures of pain, quality of life and/or psychological symptoms were reviewed. The Oxford level of evidence and Quality Assessment Tool for Quantitative Studies developed by the Effective Public Health Practice were employed.

RESULTS

A total of 4,503 studies were reviewed; seven met the inclusion criteria. The included studies were randomised controlled trials, cohort, repeated measures, and case-series studies, with most including combined treatment for CP/CPPS. Cognitive therapy, cognitive behavioural therapy, or paradoxical relaxation training were found to be effective. However, high risks of bias were found in all included studies, limiting the generalisability and reliability of findings.

CONCLUSIONS

Evidence is preliminary but shows promise for psychological treatment either as a combined or standalone treatment for CP/CPPS. However, there is a need to develop research with a more rigorous methodology to evaluate psychological treatments for men with CP/CPPS.

Heart rate variability during mindful breathing meditation

We discuss Heart Rate Variability (HRV) measured during mindful breathing meditation. We provide a pedagogical computation of two commonly used heart rate variability metrics, i.e. the root mean square of successive differences (RMSSD) and the standard deviation of RR intervals (SDRR), in terms of Fourier components. It is shown that the root mean square of successive differences preferentially weights higher frequency Fourier modes, making it unsuitable as a biosignal for mindful breathing meditation which encourages slow breathing. We propose a new metric called the autonomic balance index (ABI) which uses Respiratory Sinus Arrhythmia to quantify the fraction of heart rate variability contributed by the parasympathetic nervous system. We apply this metric to heart rate variability data collected during two different meditation techniques, and show that the autonomic balance index is significantly elevated during mindful breathing, making it a good signal for biofeedback during meditation sessions.

Neuropathic pain, cognitive fusion, and alexithymia in patients with multiple sclerosis: Cross-sectional evidence for an explanatory model of anxiety symptoms

Multiple sclerosis (MS) presents a high prevalence, a marked increase worldwide, and a relevant impact on patients, public health, and society. Anxiety often cooccurs with MS and can contribute to the worsening of MS symptoms. However, knowledge about predictors of anxiety in Patients with MS (PwMS) is scarce.

OBJECTIVE

This preliminary study explored a novel model for anxiety symptoms in PwMS, including neuropathic pain (NeP), cognitive fusion (CF), experiential avoidance (EA), and alexithymia as explanatory factors.

METHOD

This cross-sectional study integrated two independent convenience samples: 107 PwMS recruited from the Portuguese Society for Multiple Sclerosis and 97 age- and gender-matched participants without the MS diagnosis (no-MS sample) recruited from the Portuguese general population. Self-report questionnaires that measured the constructs included in the model were administered to both groups.

RESULTS

PwMS showed significantly higher values regarding anxiety symptoms and their explanatory variables (NeP, CF, EA, alexithymia) in comparison to non-MS participants. In the MS sample, no correlations were found between anxiety symptoms and sociodemographic and clinical characteristics. NeP, CF, and alexithymia showed significant correlations with anxiety symptoms and significantly explained this symptomatology in simple linear regression models. Thus, these variables were retained in the multiple linear regression model and emerged as significant regressors that together explained 38% of the variance in anxious symptomatology in PwMS.

CONCLUSIONS

This preliminary study provides novel evidence on NeP and some maladaptive emotion regulation strategies related to EA/psychological inflexibility, as vulnerability to anxiety in PwMS can be considerably increased by CF and alexithymia. Clinical implications were discussed.

Mindful Self-Care for Caregivers: A Proof of Concept Study Investigating a Model for Embedded Caregiver Support in a Pediatric Setting

We conducted an open-trial proof of concept study to determine the safety, acceptability, and feasibility of Mindful Self-Care for Caregivers (MSCC) for parents of children with Autism Spectrum Disorders (ASD) (N = 13). The intervention was offered as a co-located care model in a pediatric specialty center where the participants' children received care. Results demonstrated that the intervention was: highly acceptable to all stakeholders (i.e., participants, the group facilitator, and center administration) and could be conducted safely by a masters-level practitioner with minimal resources. Further, secondary measures support a hypothesized interventional model of MSCC, demonstrating gains in mindfulness skills and sense of competency in the parenting role reduced perceived stress and depression in parents of children with ASD.

Examining the roles of depression, pain catastrophizing, and self-efficacy in quality of life changes following chronic pain treatment

Background

Adults with chronic pain have a lower quality of life (QOL) compared to the general population. Chronic pain requires specialized treatment to address the multitude of factors that contribute to an individual's pain experience, and effectively managing pain requires a biopsychosocial approach to improve patients' QOL.

Aim

This study examined adults with chronic pain after a year of specialized treatment to determine the role of cognitive markers (i.e., pain catastrophizing, depression, pain self-efficacy) in predicting changes in QOL.

Methods

Patients in an interdisciplinary chronic pain clinic (N = 197) completed measures of pain catastrophizing, depression, pain self-efficacy, and QOL at baseline and 1 year later. Correlations and a moderated mediation were completed to understand the relationships between the variables.

Results

Higher baseline pain catastrophizing was significantly associated with increased mental QOL (b = 0.39, 95% confidence interval [CI] 0.141; 0.648) and decreased depression (b = -0.18, 95% CI -0.306; -0.052) over a year. Furthermore, the relationship between baseline pain catastrophizing and the change in depression was moderated by the change in pain self-efficacy (b = -0.10, 95% CI -0.145; -0.043) over a year. Patients with high baseline pain catastrophizing reported decreased depression after a year of treatment, which was associated with greater QOL improvements but only in patients with unchanged or improved pain self-efficacy.

Conclusions

Our findings highlight the roles of cognitive and affective factors and their impact on QOL in adults with chronic pain. Understanding the psychological factors that predict increased mental QOL is clinically useful, because medical teams can optimize these positive changes in QOL through psychosocial interventions aimed at improving patients' pain self-efficacy.

Strength Back - A qualitative study on the co-creation of a positive psychology digital health intervention for spinal surgery patients

Introduction

Spinal surgery patients often experience pain as well as stress, anxiety or even depression before surgery, highlighting the need for better mental preparation before undergoing surgery. Acceptance and Commitment Therapy and positive psychology have proven effective in coping with chronic pain and providing long-term skills that enhance psychological flexibility and mental well-being.The aim of this study is to develop a digital intervention (app) based on Acceptance and Commitment Therapy and positive psychology in co-creation with all stakeholders, including patients and professionals. The aim of the intervention is to increase psychological flexibility and positive skills of spinal surgery patients to promote long-term resilience.

Materials and methods

In this qualitative study, individual, semi-structured interviews were held with healthcare professionals (N = 9) and spinal surgery patients (N = 12) to identify contextual factors and needs for the app. Subsequently, three focus-group sessions were held with healthcare professionals and newly recruited patients to specify relevant values. Also, a first version of the app, named Strength Back, was developed using a participatory design.

Results

The interviews confirmed the need for information and digital support to cope with insecurity, anxiety and pain, both before and after surgery. Based on iterative steps in the focus-group sessions, thirteen modules were developed focusing on procedural information, pain education, psychological flexibility and mental well-being.

Discussion

The intervention Strength Back, containing information as well as Acceptance and Commitment Therapy and positive psychology exercises, has the potential to increase psychological flexibility, enhance well-being and improve postoperative recovery after spinal surgery.

Emotion regulation and the salience network: a hypothetical integrative model of fibromyalgia

Fibromyalgia is characterized by widespread pain, fatigue, sleep disturbances and other symptoms, and has a substantial socioeconomic impact. Current biomedical and psychosocial treatments are unsatisfactory for many patients, and treatment progress has been hindered by the lack of a clear understanding of the pathogenesis of fibromyalgia. We present here a model of fibromyalgia that integrates current psychosocial and neurophysiological observations. We propose that an imbalance in emotion regulation, reflected by an overactive 'threat' system and underactive 'soothing' system, might keep the 'salience network' (also known as the midcingulo-insular network) in continuous alert mode, and this hyperactivation, in conjunction with other mechanisms, contributes to fibromyalgia. This proposed integrative model, which we term the Fibromyalgia: Imbalance of Threat and Soothing Systems (FITSS) model, should be viewed as a working hypothesis with limited supporting evidence available. We hope, however, that this model will shed new light on existing psychosocial and biological observations, and inspire future research to address the many gaps in our knowledge about fibromyalgia, ultimately stimulating the development of novel therapeutic interventions.

Designing voice interfaces to support mindfulness-based pain management

Objective

Chronic pain is a critical public health issue affecting approximately 20% of the adult population in the United States. Given the opioid crisis, there has been an urgent focus on non-addictive pain management methods including mindfulness-based stress reduction (MBSR). Prior work has successfully used MBSR for pain management. However, ensuring longitudinal engagement in MBSR practices remains a serious challenge. In this work, we explore the utility of a voice interface to support MBSR home practice.

Methods

We interviewed 10 mindfulness program facilitators to understand how such a technology might fit in the context of the MBSR class and identify potential usability issues with our prototype. We then used directed content analysis to identify key themes and sub-themes within the interview data.

Results

Our findings show that facilitators supported the use of the voice interface for MBSR, particularly for individuals with limited motor function. Facilitators also highlighted the unique affordances of voice interfaces, including perceived social presence, to support sustained engagement.

Conclusion

We demonstrate the acceptability of a voice interface to support home practice for MBSR participants among trained mindfulness facilitators. Based on our findings, we outline design recommendations for technologies aiming to provide longitudinal support for mindfulness-based interventions. Future work should further these efforts toward making non-addictive pain management interventions accessible and efficacious for a wide audience of users.

Remotely Delivered Psychologically Informed Mindful Movement Physical Therapy for Pain Care: A Framework for Operationalization

Background

While there is recognition by the greater medical community and physical therapists to address the biopsychosocial needs of people with chronic, persistent pain, there are challenges in implementation and delivery including wide variability in interventions, lack of clear rationale, and absence of clinical models that are feasible and acceptable on a large scale. Important components for psychologically informed physical therapy (PiPT) for pain care include behavioral approaches (e.g., Acceptance and Commitment Therapy), mindfulness, pain neuroscience education, motivational interviewing (MI), and interoceptive skills-building. The Empower Veterans Program (EVP) Mindful Movement framework blends these components and emphasizes a mindfulness and self-compassion approach with MI and body-based experiential learning. This program was offered in-person at the Atlanta and Maryland VA Health Care Centers with published positive Patient Reported Outcomes (PRO) pre-COVID 19 crisis and shifted to entirely remote delivery in March 2020.

Objective

This paper offers an evidence-based and theory driven framework to operationalize a remotely delivered group-based psychologically informed mindful movement physical therapy intervention as part of an interdisciplinary pain care program.

Methods

Since 2021 PRO and demographics are collected using a survey administered through Qualtrics over a 12-month period at baseline, immediately post TelePain EVP, at 6 months, and at 12 months, with findings forthcoming.

Discussion/Results

Tele-pain EVP offers 6-9 groups a week with 7-9 veterans from Atlanta based team and 3-4 groups a week with 5-9 veterans from Maryland based team. Adaptations for remote delivery optimized mindfulness and active learning strategies including interoceptive skills-building and use of MI to support self-efficacy to trust, restore a sense of safety in the body, and explore adaptations for safe movement.

Conclusion

TelePain-EVP Mindful Movement provides a framework for other programs to translate for their populations and systems to further develop best practices in PiPT for pain care and integration into interdisciplinary care.

Flourishing among adolescents living with chronic pain and their parents: A scoping review

Evidence exists regarding the impact of flourishing in individuals living with chronic pain, but there are currently no reviews which collate the literature on flourishing in adolescents living with chronic pain and their parents. Therefore, the aim of this scoping review was to map and review the current literature, to document how flourishing is defined and understood in the literature, and to identify gaps in the field. Six databases were searched (Web of Science, Medline, Embase, APA PsycNet and the Cochrane Central Register of Controlled Trials). In addition, a limited gray literature search was conducted. The resulting data were collated and reported in relation to the review questions, by examining the included papers to search for the presence of flourishing. Database searches resulted in 7326 papers after duplicate removal, with eight remaining papers being assessed for full-text eligibility. Following full-text screening, a final four papers were included in the review. Within the papers, flourishing was defined in relation to commonalities of benefit finding, enhanced maturity and growth, and social support. Gaps in the literature and directions for future research are considered. This review suggests that there is a dearth of knowledge and research regarding flourishing among adolescents living with chronic pain and their parents, despite aspects of flourishing identified in limited literature. This warrants further investigation.

Psychological Evaluation and Management of Chronic Pancreatitis

Chronic pancreatitis is a chronic digestive disorder that greatly diminishes the quality of life and is associated with significant psychological distress. A best practice recommendation in treating chronic pancreatitis is offering care in a multidisciplinary model that includes access to a behavioral health provider among other medical professionals. Behavioral interventions for patients with chronic pancreatitis have promise to improve the management of pain, comorbid psychiatric symptoms, and quality of life. If surgical interventions such as a total pancreatectomy islet autotransplant are considered, evaluating and mitigating psychosocial risk factors may aid the selection of appropriate candidates.

Does resilience predict hospital length of stay after total knee arthroplasty? A prospective observational cohort study

Background

Resilience, or the ability to bounce back from stress, is a key psychological factor that is associated with ongoing functional independence and higher quality of life in older adults in the context of chronic health conditions. Emerging research has explored resilience and patient-reported outcomes after TKA. Our primary aim was to explore the relationship between resilience and acute hospital length of stay after total knee arthroplasty (TKA).

Methods

A prospective observational study recruited 75 participants one month before total knee arthroplasty from two Australian hospitals. Two preoperative psychological measures were used: the Brief Resilience Scale, and for comparison, the Depression, Anxiety and Stress Scale-21 (DASS-21). We collected sociodemographic, medical and surgical details, patient-reported pain, function, fatigue and quality of life one month before TKA. Health service data describing acute hospital length of stay, inpatient rehabilitation use, and physiotherapy occasions of service were collected after TKA. Non-parametric analysis was used to determine any differences in length of stay between those with low or high resilience and DASS-21 scores. Secondary regression analysis explored the preoperative factors affecting acute hospital length of stay.

Results

No significant difference was detected in length of stay between those with a low or a high resilience score before TKA. However, the group reporting psychological symptoms as measured by the DASS-21 before TKA had a significantly longer acute hospital length of stay after TKA compared to those with no psychological symptoms [median length of stay 6 (IQR 2.5) days vs. 5 (IQR 2) days, respectively (Mann-Whitney U = 495.5, P=0.03)]. Multivariate regression analysis showed that anesthetic risk score and fatigue were significant predictors of length of stay, with the overall model demonstrating significance (χ2=12.426, df = 4, P=0.014).

Conclusions

No association was detected between the brief resilience score before TKA and acute hospital length of stay after TKA, however, symptoms on the DASS-21 were associated with longer acute hospital length of stay. Preoperative screening for psychological symptoms using the DASS-21 is useful for health services to identify those at higher risk of longer acute hospital length of stay after TKA.

A qualitative systematic review and meta-aggregation of the experiences of men diagnosed with chronic lymphoedema

BACKGROUND

Lymphoedema is a chronic condition that is estimated to affect up to four people per 1000 of the UK population with this increasing with age. Men account for up to 20% of lymphoedema service caseloads with research focussing upon women affected.

AIMS

To retrieve primary qualitative research on the experiences of men with chronic lymphoedema.

METHODS

A qualitative review was undertaken using the Joanna Briggs Institute (JBI) meta-aggregation method. A search strategy was applied to 12 databases, from inception to February 2021, with 22 studies identified and appraised. The findings were extracted and synthesised via the JBI approach.

RESULTS

Four synthesised findings were identified: (1) The 'New Norm', how diagnosis led to men being faced with a 'new version' of themselves; (2) 'Journey into the Unknown' relates to the unforeseen diagnosis of the condition; (3) 'Access' - challenge in receiving a diagnosis, and support; and (4) 'Personhood' - the impact of the condition upon external constructs and relationships.

CONCLUSIONS

Men are faced with similar challenges as women coupled with societal expectations with respect to gender identity and expression. This leads to those wishing to engage with men to adopt 'gender-based tailoring' within healthcare services, information and support.

A randomised controlled trial of acceptance and commitment therapy plus usual care compared to usual care alone for improving psychological health in people with motor neuron disease (COMMEND): study protocol

BACKGROUND

Motor neuron disease (MND) is a rapidly progressive, fatal neurodegenerative disease that predominantly affects motor neurons from the motor cortex to the spinal cord and causes progressive wasting and weakening of bulbar, limb, abdominal and thoracic muscles. Prognosis is poor and median survival is 2-3 years following symptom onset. Psychological distress is relatively common in people living with MND. However, formal psychotherapy is not routinely part of standard care within MND Care Centres/clinics in the UK, and clear evidence-based guidance on improving the psychological health of people living with MND is lacking. Previous research suggests that Acceptance and Commitment Therapy (ACT) may be particularly suitable for people living with MND and may help improve their psychological health.

AIMS

To assess the clinical and cost-effectiveness of ACT modified for MND plus usual multidisciplinary care (UC) in comparison to UC alone for improving psychological health in people living with MND.

METHODS

The COMMEND trial is a multi-centre, assessor-blind, parallel, two-arm RCT with a 10-month internal pilot phase. 188 individuals aged ≥ 18 years with a diagnosis of definite, laboratory-supported probable, clinically probable, or possible familial or sporadic amyotrophic lateral sclerosis, and additionally the progressive muscular atrophy and primary lateral sclerosis variants, will be recruited from approximately 14 UK-based MND Care Centres/clinics and via self-referral. Participants will be randomly allocated to receive up to eight 1:1 sessions of ACT plus UC or UC alone by an online randomisation system. Participants will complete outcome measures at baseline and at 6- and 9-months post-randomisation. The primary outcome will be quality of life at six months. Secondary outcomes will include depression, anxiety, psychological flexibility, health-related quality of life, adverse events, ALS functioning, survival at nine months, satisfaction with therapy, resource use and quality-adjusted life years. Primary analyses will be by intention to treat and data will be analysed using multi-level modelling.

DISCUSSION

This trial will provide definitive evidence on the clinical and cost-effectiveness of ACT plus UC in comparison to UC alone for improving psychological health in people living with MND.

Stress, coping and the acceptability of mindfulness skills among pregnant and parenting women living with HIV in the United States: A focus group study

Pregnant and parenting women living with HIV (WLWH) face high levels of psychological stress and mental illness but lack tailored and acceptable psychosocial treatments. The research team sought to inform the adaptation of a mindfulness intervention for pregnant and parenting WLWH through focus groups exploring psychosocial treatment needs and mindfulness intervention preferences. The research team conducted focus groups with pregnant and parenting WLWH (n = 16) and case managers (n = 6) recruited from a community-based enhanced case management program. The research team utilised an iterative inductive approach to coding of the transcripts from these focus groups. Five themes emerged: stressors, signs of stress, coping, lack of access and acceptability of care, and motivation and trust in care engagement. These focus groups revealed a desire for a group intervention that could decrease isolation while protecting against involuntary disclosure of HIV status. Participants expressed openness to mindfulness skills for coping with stress. The focus group participants' preference for a non-stigmatising group intervention supports the potential of a mindfulness-based group intervention to reduce stress and improve the mental health of pregnant and parenting women living with HIV.

Inpatient suicide in psychiatric settings: Evaluation of current prevention measures

The risk of suicide in psychiatric hospitals is 50 times higher than in the general population, despite patient safety being a priority for any hospital. However, to date, due to the complexity of assessing suicide risk, there has been no consensus on the suicide prevention measures that should be in place in hospitals. The aim of this work is: To provide an overview of the progress that has been made in the field of inpatient suicide prevention in recent years; discuss the problems that remain; and suggest potential future developments. As new clinical dimensions (notably anhedonia, psychological pain and hopelessness) develop, they should become new therapeutic targets. Team training (like the Gatekeeper Training Program) and the latest advances in suicide risk assessment (such as the Collaborative Assessment and Management of Suicidality) should be implemented in psychiatric wards. Suicide prevention plans (e.g., ASSIP, SAFE-T, etc.) represent easy-to-administer, low-cost interventions. The Mental Health Environment of Care Checklist has been proven effective to reduce suicide risk at hospitals. Furthermore, the types of psychotherapy recommended to reduce suicide risk are cognitive behavioral therapy (CBT) and dialectical behavioral therapy (DBT). There are several pharmacological treatments for suicide risk, such as lithium and clozapine, which have been shown to be effective in the long term, as well as ketamine and esketamine, which are more effective in the short term. Following some encouraging recent results, buprenorphine may also be proposed to patients with a suicide risk. Triple chronotherapy rapidly improves depressive symptoms over 9 weeks. Regarding brain stimulation techniques, rTMS has proven to be effective in alleviating multiple dimensions of suicidality.

Lessons Learned from an Attempted Pragmatic Randomized Controlled Trial for Improvement of Chronic Pain-Associated Disability in Green Professions: Long-Term Effectiveness of a Guided Online-Based Acceptance and Commitment Therapy  (PACT-A)

Musculoskeletal symptoms are increased in farmers, whereas the prevalence of chronified pain is unknown. Online interventions based on acceptance and commitment therapy (ACT) have shown encouraging results in the general population, representing a promising approach for reducing pain interference in green professions (i.e., farmers, foresters, gardeners). We conducted a pragmatic RCT comparing a guided ACT-based online intervention to enhanced treatment-as-usual in entrepreneurs, contributing spouses, family members and pensioners in green professions with chronic pain (CPG: ≥grade II, ≥6 months). Recruitment was terminated prematurely after 2.5 years at N = 89 (of planned N = 286). Assessments were conducted at 9 weeks (T1), 6 months (T2) and 12 months (T3) post-randomization. The primary outcome was pain interference (T1). The secondary outcomes encompassed pain-, health- and intervention-related variables. No treatment effect for reduction of pain interference was found at T1 (β = -0.16, 95%CI: -0.64-0.32, p = 0.256). Improvements in cognitive fusion, pain acceptance, anxiety, perceived stress and quality of life were found only at T3. Intervention satisfaction as well as therapeutic and technological alliances were moderate, and uptake and adherence were low. Results are restricted by low statistical power due to recruitment issues, high study attrition and low intervention adherence, standing in contrast to previous studies. Further research is warranted regarding the use of ACT-based online interventions for chronic pain in this occupational group. Trial registration: German Clinical Trial Registration: DRKS00014619.

Pain reduction in fibromyalgia syndrome through pairing transcranial direct current stimulation and mindfulness meditation: A randomized, double-blinded, sham-controlled pilot clinical trial

Background

This double-blinded, randomized and sham-controlled pilot clinical trial aimed to investigate the preliminary clinical efficacy and feasibility of combining mindfulness meditation (MM) and transcranial direct current stimulation (tDCS) for pain and associated symptoms in patients with fibromyalgia syndrome (FMS).

Methods

Included FMS patients (age: 33 to 70) were randomized to three different groups to receive either ten daily sessions of anodal tDCS over the left primary motor cortex paired with MM for 20 min (active + MM, n = 10), sham tDCS combined with MM (sham + MM, n = 10) or no intervention (NoT, n = 10). Patients in the bimodal therapy groups received a week of training in MM prior to the stimulation. Participants reported pain intensity, the primary outcome, by filling in a pain diary daily throughout the whole study. They were also evaluated for quality of life, pressure pain sensitivity, psychological wellbeing, sleep quality and sleep quantity. Assessments were performed at three time points (baseline, immediately after treatment and one-month follow-up).

Results

Participants in the active + MM group did not exhibit reduced pain intensity following the bimodal therapy compared to controls. Patients in active group demonstrated clinically meaningful and significantly higher quality of life following the therapeutic intervention than other groups. There was no significant difference among groups regarding pressure pain sensitivity, sleep parameters and psychological scales. The combined treatment was well tolerated among participants, with no serious adverse effects.

Conclusion

This study was the first to pair these two effective non-pharmacological therapies for pain management in FMS. In the light of an underpowered sample size, repetitive anodal tDCS combined with MM did not improve pain or FMS-associated symptoms. However, patients in the active + MM group reported higher quality of life than the control groups. Studies with more participants and longer follow-ups are required to confirm our findings.

Management of chronic migraine

Chronic migraine is a neurologic disorder associated with considerable disability, lost productivity, and a profound economic burden worldwide. The past five years have seen a dramatic expansion in new treatments for this often challenging condition, among them calcitonin gene related peptide antagonists and neuromodulatory devices. This review outlines the epidemiology of and diagnostic criteria and risk factors for chronic migraine. It discusses evidence based drug and non-drug treatments, their advantages and disadvantages, and the principles of patient centered care for adults with chronic migraine, with attention to differential diagnosis and comorbidities, clinical reasoning, initiation and monitoring, cost, and availability. It discusses the international guidelines on drug treatment for chronic migraine and evaluates non-drug treatments including behavioral and complementary therapies and lifestyle modifications. Finally, it discusses the management of chronic migraine in special populations, including pediatrics, pregnancy, and older people, and considers future questions and emerging research in the field.

Mindfulness-Based Interventions: Focus on Pediatric Type 1 and Type 2 Diabetes

PURPOSE OF REVIEW

Mindfulness-based interventions (MBIs) focus on promoting nonjudgmental, purposeful awareness of the present experience, and they include specific components such as body scan, meditation, and breathing techniques for healthier coping with stress and reduced negative affect. In adult populations with chronic illness (e.g., type 1 diabetes [T1D], type 2 diabetes [T2D], overweight), MBIs have been shown to improve psychosocial outcomes with some improvements in health outcomes as well. Youth with T1D/T2D frequently experience heightened depression as well as diabetes distress, which are associated with less frequent blood glucose monitoring, insulin administration, and nutrition oversight. Thus, MBIs have potential to alleviate psychosocial distress in youth with T1D/T2D and also improve health outcomes. This paper is a review of the literature on potential psychosocial and health benefits of MBIs for youth with T1D/T2D.

RECENT FINDINGS

Among youth with T1D/T2D, MBIs have been shown to reduce symptoms of depression and diabetes distress. Improvements in health outcomes, such as A1c, have been inconsistent across studies. Although research on the efficacy of MBIs to improve psychosocial and health outcomes in youth with T1D/T2D is promising, this area of study is in its early stages. Future investigation of MBIs in youth with T1D and T2D is warranted, recognizing that these are heterogeneous groups with potential benefit of specifically tailored interventions.

The Effects of Mindfulness Interventions on Fibromyalgia in Adults aged 65 and Older: A Window to Effective Therapy

Pain usually receives insufficient attention by individuals due to the misconception that pain is a natural consequence of aging. For persons aged 65 and older, a disease requiring further research is fibromyalgia, characterized by chronic pain without clear pathology. Mind-body therapies like mindfulness are beneficial for this population as they affect psychological and biological aspects of pain. These therapies emphasize a nonjudgmental acceptance of thoughts and attention to the experience without attempting to resist or change them. Despite the potential benefits of mindfulness interventions for persons with fibromyalgia aged 65 and older, only few studies have examined the effects of these therapies, yielding conflicting findings. Importantly, no study has yet to be conducted exclusively on this population. This comprehensive review examined existing literature focusing on the effects of mindfulness-based interventions on the physical and mental well-being of persons with fibromyalgia aged 65 and older. It highlights the need for further research on the relationship between mindfulness, fibromyalgia, and gerontology, calling for a standard protocol of intervention.

Convergence mechanism of mindfulness intervention in treating attention deficit hyperactivity disorder: Clues from current evidence

This paper reviews the underlying evidence for various aspects of the convergence mechanism of mindfulness intervention in attention deficit hyperactivity disorder (ADHD). There may be compatibility among various ADHD remission models and the therapeutic mechanism of mindfulness intervention in ADHD may be mainly via the convergence mechanism. However, neuroimaging-based analysis of the mechanisms of mindfulness intervention in treating ADHD is lacking. Differences in the efficacy of various subtypes of mindfulness intervention, and corresponding specific imaging changes need further investigation. Future research may focus on the neuroimaging features of specific mindfulness intervention subtypes.

The acceptability of photovoice as a method for incorporating resilience-enhancing factors into pediatric pain research

Recurrent or chronic pain affects 11–38% of children and adolescents. Pediatric pain research typically focuses on risk factors, such as anxiety and parent functional disability, but resilience-building, protective factors also play an important role in the pain experience. New methods to incorporate resilience-enhancing factors into pain research are needed. Photovoice is a highly participatory research method, where participants take photos to address a common question, caption their photos, and discuss the meaning of the photos in a group. The main objective of this study was to determine whether photovoice is an acceptable method to young people living with chronic pain for identifying and sharing sources of joy. Another objective was to explore sources of joy. Sixteen adolescents and young adults participated, which involved meeting in a group to discuss the goal of the study, taking photographs of self-identified sources of joy over a two-week period, and meeting as a group again to discuss the photographs and participate in a focus group about the experience. Results suggest that photovoice is an acceptable method, as all participants took photographs and attended both meetings, and three themes from the focus group data suggested the participants considered photovoice to be appropriate: 1.) Relief associated with meeting peers, 2.) Potential to benefit young people living with pain, and 3.) Potential to raise awareness. Three themes emerged from the discussion of the photographs to describe sources of joy: 1.) Gratitude for everyday pleasures and accomplishments, 2.) Support from pets, and 3.) Journey of acceptance. Results add to the strengths-based literature on pediatric pain by identifying an acceptable method that could be further explored for use as an intervention to enhance protective factors such as positive affect, gratitude, and social support and to compare the experiences of different populations of youth living with pain.

Definition and refinement of HYlaDO, a self-hypnosis training program for chronic pain management: A qualitative exploratory study

One in four Canadians is affected by chronic pain, frequently treated with opioids, which present a risk of addiction and overdose. The development of non-pharmacological interventions is therefore crucial. In a pilot project, a self-hypnosis training program showed encouraging results in improving breast cancer patients' quality of life. Based on this program, we developed a new self-hypnosis program for chronic pain patients: HYlaDO (Hypnosis of pain in French, HYpnose de la DOuleur). To structure the process of adapting an existing program to a new context, we used the ORBIT model (Obesity-Related Behavioral Intervention Trials), which consists of four development phases. This study aimed to collect patients' opinions and recommendations, and to refine HYlaDO (ORBIT Phase Ib). Fifteen participants took part in individual semi-structured interviews about this program. Two analysts coded the verbatims, and a thematic categorization was performed. Six themes emerged: practice training, expected vs. perceived effects, chronic pain management, individual practice, satisfaction, and participants' recommendations. Improvements to be considered in this type of program were finally discussed.

Effectiveness of the online Acceptance and Commitment Therapy intervention "Embrace Pain" for cancer survivors with chronic painful chemotherapy-induced peripheral neuropathy: study protocol for a randomized controlled trial

BACKGROUND

About 30% of cancer survivors suffer from chemotherapy-induced peripheral neuropathy (CIPN) ≥6 months after completion of chemotherapy. This condition, for which treatment options are scarce, comes with limitations in daily life functioning and decreased quality of life. The current study examines the effectiveness of an online self-help intervention based on Acceptance and Commitment Therapy (ACT) in comparison to a waiting list condition (WLC) to deal with CIPN. In addition, it examines which factors moderate effects and to what extent the effects differ between guided and unguided ACT intervention.

METHODS

A two-parallel, non-blinded randomized controlled trial (RCT) will be carried out. Adult cancer survivors who experience painful CIPN for at least 3 months and completed chemotherapy at least 6 months ago will be recruited (n=146). In the intervention condition, participants will follow an 8-week self-management course containing 6 modules regarding psychoeducation and ACT processes, including therapeutic email guidance. By means of text and experiential exercises, supplemented with illustrations, metaphors, and audio files, people will learn to carry out value-oriented activities in their daily life with pain. Participants will learn new ways of coping with pain, including reducing pain avoidance and increasing pain acceptance. Participants in the WLC will be invited to follow the intervention without therapeutic guidance 5 months after start. Pain interference is the primary outcome, while psychological distress, quality of life, CIPN symptom severity, pain intensity, psychological flexibility, mindfulness skills, values-based living, and pain catastrophizing will serve as secondary outcomes. All outcome measures will be evaluated at inclusion and baseline, early-intervention, mid-intervention, post-treatment, and 3- and 6-month post-treatment. Qualitative interviews will be conducted post-treatment regarding experiences, usage, usability, content fit, and satisfaction with the intervention.

DISCUSSION

This study will provide valuable information on the effectiveness of an online self-help intervention based on ACT versus WLC for chronic painful CIPN patients.

An integrated mindfulness meditation and acceptance and commitment therapy intervention for chronic pain: Rationale, design, and methodology of a pilot randomized controlled trial of Acting with Mindfulness for Pain (AMP)

Acceptance and commitment therapy (ACT) is an evidence-based psychosocial intervention for chronic pain; however, in its present form ACT produces modest improvements in function and is no more effective than cognitive behavioral therapy (CBT), the current gold standard. This protocol paper describes the Acting with Mindfulness for Pain (AMP) protocol, which emphasizes and integrates formal mindfulness meditation practice within an ACT-based approach. This paper presents the rationale, design and methodology of an ongoing pilot randomized controlled trial (RCT) comparing AMP to CBT among Veterans with chronic pain (N = 86). Specifically, we argue that formal meditation practice is a necessary treatment component that directly targets key ACT processes which will help facilitate large treatment effects on function (e.g., general activity, social relationships, life enjoyment) among individuals with chronic pain. This study will be the first to consider formal mindfulness meditation practice as a principal treatment ingredient in the context of ACT for chronic pain. The purpose of this trial is to evaluate the feasibility of recruitment and collection of measures, and to examine preliminary treatment effects to determine the appropriateness of a subsequent full-scale RCT. This study will also explore within and between group change on primary and secondary outcomes including pain interference, pain acceptance, trait mindfulness, pain catastrophizing, values-based living, quality of life, practice adherence, and objective measures of physical activity. This study will help delineate the role of formal mindfulness practice within an ACT-based approach for chronic pain and provide preliminary data for a future fully powered RCT.

Exploring the past, present, and future of the mindfulness field: A multitechnique bibliometric review

This paper provides an overview of the mindfulness literature up until the end of 2020 by (a) uncovering its underlying intellectual structure, (b) identifying the most influential and popular themes, and (c) presenting new directions for future research on mindfulness. To this end, a systematic quantitative review based on bibliometric methods was conducted, which is perhaps less prone to researcher bias and can complement existing meta-analyses and qualitative (narrative) structured reviews as an objective approach. Three bibliometric techniques—document co-citation analysis, co-word (co-occurrence and content) analysis, and bibliographic coupling—were applied to explore the past, present, and future of mindfulness research. The co-citation analysis showed that measurement, mechanisms, mindfulness-based interventions, and examinations of the efficacy of mindfulness interventions are among the key theoretical knowledge bases from which the field of mindfulness is derived. The content analysis demonstrated the beneficial effects of mindfulness meditation for physical and mental health conditions. The bibliographic coupling revealed novel directions in cognitive behavioral therapy, emotion regulation, the application of mindfulness practice to children and adolescents, mindfulness at work, and the role of mindfulness in positive psychology. The large sample of articles that was analyzed allowed us to provide a broader and more objective overview than possible with other forms of literature reviews. The combination of the three bibliometric techniques granted deeper insights into the complex multidisciplinary field of mindfulness, along with specific suggestions for future research.

Usability Study of the iACTwithPain Platform: An Online Acceptance and Commitment Therapy and Compassion-Based Intervention for Chronic Pain

Background

This pilot study aims to test the usability of the iACTwithPain platform, an online ACT-based intervention for people with chronic pain, to obtain information on which intervention and usability aspects need improvement and on expected retention rates.

Methods

Seventy-three Portuguese women with chronic pain were invited to complete the first three sessions of the iACTwithPain intervention assess their quality, usefulness and the platform’s usability. Twenty-one accepted the invitation. Additionally, eight healthcare professionals working with chronic medical conditions assessed the platform and the intervention from a practitioner’s point of view.

Results

This study presented a considerable attrition rate (71.43%) among chronic pain participants, with six completers. There were no significant differences in demographic or clinical variables between dropouts and completers except for completed education (participants who dropped out presented less education than completers). Reasons for dropout were related to difficult personal events occurring during the time of the intervention, lack of time, or having forgotten. There seemed to be an overall satisfaction with both the intervention, its contents and form of presentation of information, and the platform, concerning its design, appearance, and usability. Real image videos were preferred over animations or audio by chronic pain participants. Healthcare professionals emphasized the appealing and dynamic aspects of the animation format.

Conclusion

This study informs the ongoing improvement of the iACTwithPain platform and provides valuable information on aspects researchers should consider while developing online psychological interventions for chronic pain. Further implications are discussed.

Incremental validity of acceptance over coping in predicting adjustment to endometriosis

Psychological acceptance has emerged as an important construct to explain low psychological distress in different clinical samples. However, the incremental validity of psychological acceptance to explain adjustment to medical conditions over other related and well-established constructs, such as coping, is relatively unclear. This study explored whether psychological acceptance significantly contributes to explain adjustment above and beyond coping in females with endometriosis. A total of 169 females (M_age = 34.95 years; SD_age = 6.07 years) with endometriosis and pain symptoms completed the Acceptance and Action Questionnaire-II, the Brief-COPE, the Hospital Anxiety and Depression Scale, the Psychological Wellbeing Scale, and the Endometriosis Health Profile-5. We conducted Hierarchical Regression Analyses to determine the contribution of psychological acceptance to explaining adjustment. The results showed that the contribution of psychological acceptance ranged from 11 to 20% when controlling for coping, while coping explained from 1 to 8% when the model was reversed. The findings suggest that psychological acceptance is a more useful construct than coping for predicting PD and other psychological outcomes in females with endometriosis.

Effects of group Acceptance and Commitment Therapy (ACT) on anxiety and depressive symptoms in adults: A meta-analysis

BACKGROUND

A comprehensive meta-analysis quantitatively examining the effects of group Acceptance and Commitment Therapy (ACT) on anxiety and depressive symptoms is required to advance our understanding of its efficacy and moderating factors.

METHODS

Four electronic databases were searched in August 2018. An update search was conducted in November 2021. Forty-eight randomised controlled trials (RCTs) were included in this review (3292 participants: anxiety = 34 RCTs, depression = 40 RCTs).

RESULTS

The overall effect size for anxiety symptoms was medium-to-large (g = 0.52, p < 0.001; 95% CI = 0.30-0.73), while the overall effect size was small-to-medium for depressive symptoms (g = 0.47, p < 0.001; 95% CI = 0.31-0.64). Subgroup analyses demonstrated that group ACT was significantly superior to non-active controls (e.g., waiting list) in reducing anxiety and depressive symptoms. Group ACT was only significantly superior to active controls (e.g., CBT) in reducing depressive symptoms. Subgroup analyses also demonstrated that the effect size can vary depending on the number of sessions provided and the primary condition of participants recruited.

LIMITATIONS

The number of studies included in each category of subgroup analyses was small and the risk of bias varied across studies. There was high heterogeneity among the included studies, and this might have affected the results.

CONCLUSION

The current evidence suggests that group ACT may be effective in treating anxiety and depressive symptoms, perhaps more so for depressive symptoms when compared to other well-established treatments. The intensity of treatment and the targeted population may need to be considered when delivering group ACT.

Pre- and post-operative psychological interventions to prevent pain and fatigue after breast cancer surgery (PREVENT): Protocol for a randomized controlled trial

Background

Breast cancer is the most common cancer type among women worldwide with over a million new cases each year. More than 40% of these women will struggle with chronic pain and fatigue after surgery, regardless of surgical procedure. These consequences are detrimental and result in distress and disability, including work disability. Few attempts have been made to prevent chronic pain and fatigue after surgery by applying a psychological approach, despite psychological risk factors being crucial in the development of both chronic pain and fatigue. In this study, we aim to develop and test an easily implementable strategy of preventing chronic pain and fatigue after breast cancer surgery. The intervention strategy involves a pre-operative hypnosis session and a web-based post-operative Acceptance and Commitment Therapy (ACT). The hypnosis has previously been found effective in alleviating acute post-operative pain and fatigue in breast cancer patients, while ACT is well suited to cancer populations as it offers a model of healthy adaptation to difficult circumstances. Together they form an intervention strategy with both a preventive and a rehabilitative focus.

Methods/Design

This randomized controlled trial aims to estimate the effects of the pre- and post- operative interventions compared to attentional control and treatment as usual (TAU) and will also include a qualitative process evaluation. Participants will be randomized to receive either a pre-operative brief hypnosis session and a post-operative web-based psychological intervention (iACT) or a pre-operative one-session mindfulness through an audio file and post-operative TAU. Self-reported questionnaire data and biomarker data will be assessed pre-surgery, post-surgery and 3 and 12 months after surgery. In addition, we will assess registry data on sick leave and prescriptions until 2-year follow-up. In the qualitative process evaluation, data will be collected from participants from both study arms (through interviews and a diary) and two different analyses performed (socio-narrative and Grounded Theory) with the objective to describe the development of chronic post-surgical pain and fatigue and the potential influence of the interventions on these processes. The study is set-up to demonstrate a minimum difference in pain of 1 point on NRS (0–10) and 3 points on FACIT-F (0–52) between the groups at 3-months follow-up by including 200 breast cancer patients in total.

Discussion

This trial will be the first study to estimate the effect of a combined pre-operative hypnosis with a post-operative iACT to prevent pain and fatigue after breast cancer surgery. The results from our study might i) help the large group of women affected by chronic pain and fatigue after breast cancer surgery, ii) shed light on the mechanisms involved in chronic pain and fatigue development, and iii) serve as a model for other surgical procedures.

Mindfulness-Based Stress Reduction in Breast Cancer Survivors with Chronic Neuropathic Pain: A Randomized Controlled Trial

Objectives

The purpose of this study was to compare the effects of group-delivered mindfulness-based stress reduction as compared to a waitlist control group among breast cancer survivors living with CNP.

Methods

A randomized controlled trial design was applied, and outcomes collected included pain, emotional function, quality of life, and global impression of change.

Results

A total of 98 women were randomized and included in analyses. The sample included 49 women in the mindfulness-based stress reduction group, and 49 women in the waitlist control group. The intervention group participants (mean age 51.3 years, standard deviation = 11.4) and waitlist participants (mean age 55.1 years, standard deviation = 9.6) reported an average pain duration of approximately three years. No significant differences were found on the primary outcome of the proportions of women with reduced pain interference scores from the time of randomization to 3 months after the intervention was received. No significant changes were found among secondary outcomes.

Conclusion

Our randomized clinical trial did not find significant benefits of group-based mindfulness-based stress reduction for the management of CNP. The current study findings should be replicated and are important to consider given ongoing concerns that nonsignificant results of mindfulness-based stress reduction are often unpublished.

Mental Health in Athletes: Where Are the Treatment Studies?

In recent years, athletes’ mental health has gained interest among researchers, sport practitioners, and the media. However, the field of sport psychology lacks empirical evidence on the effectiveness of psychotherapeutic interventions for mental health problems and disorders in athletes. Thus far, intervention research in sport psychology has mainly focused on performance enhancement using between-subject designs and healthy athlete samples. In the current paper, we highlight three interrelated key issues in relation to treating mental health problems and disorders in athletes. (i) How are mental health and mental health problems and disorders defined in the sport psychology literature? (ii) How are prevalence rates of mental health problems and disorders in athletes determined? (iii) What is known about psychotherapeutic interventions for mental health problems and disorders in athletes? We conclude that the reliance on different definitions and assessments of mental health problems and disorders contributes to heterogeneous prevalence rates. In turn, this limits our understanding of the extent of mental health problems and disorders in athletes. Furthermore, knowledge of the effectiveness of psychotherapeutic interventions for athletes with mental health problems and disorders is scarce. Future research should include athletes with established mental health problems and disorders in intervention studies. We also propose an increased use of N-of-1 trials to enhance the knowledge of effective psychotherapeutic interventions in this population.

Self-administered transcranial direct current stimulation for pain in older adults with knee osteoarthritis: A randomized controlled study

BACKGROUND

Knee osteoarthritis (OA) is a leading cause of pain in older adults. Previous studies indicated clinic-based transcranial direct current stimulation (tDCS) was effective to reduce pain in various populations, but no published studies have reported the efficacy of home-based self-administered tDCS in older adults with knee OA using a randomized clinical study.

OBJECTIVE

The purpose of this study was to evaluate the efficacy and feasibility of tDCS on clinical pain intensity in adults with knee OA pain.

METHODS

One hundred twenty participants aged 50-85 years with knee OA pain were randomly assigned to receive fifteen daily sessions of 2 mA tDCS for 20 min (n = 60) or sham tDCS (n = 60) over 3 weeks with remote supervision via telehealth. Clinical pain intensity was measured by the Numeric Rating Scale and Western Ontario and McMaster Universities Osteoarthritis Index. Also, we collected data on the tDCS experience via a questionnaire.

RESULTS

Participants (68% female) had a mean age of 66 years. Active tDCS significantly reduced pain intensity compared to sham tDCS after completion of the fifteen daily sessions (Cohen's d = 1.20; p-value < 0.0001). Participants showed high levels of satisfaction with their tDCS experience, and there have been no adverse events.

CONCLUSION

We demonstrated that home-based self-administered tDCS was feasible and reduced clinical pain intensity in older adults with knee OA, which can increase its accessibility. Future studies with multi-site randomized controlled trials are needed to validate our findings.

Trajectories and Individual Differences in Pain, Emotional Distress, and Prescription Opioid Misuse During the COVID-19 Pandemic: A One-Year Longitudinal Study

Recent studies suggest that the COVID-19 pandemic can serve as a unique psychosocial stressor that can negatively impact individuals with chronic pain. Using a large online sample in the U.S., the present study sought to investigate the impact of the pandemic on the trajectories of pain severity and interference, emotional distress (ie, anxiety and depressive symptoms), and opioid misuse behaviors across one year. Potential moderating effects of socio-demographic factors and individual differences in pain catastrophizing, pain acceptance, and sleep disturbance on outcome trajectories were also examined. Adults with chronic pain were surveyed three times across 1 year (April/May 2020 [N = 1,453]; June/July 2020 [N = 878], and May 2021 [N = 813]) via Amazon's Mechanical Turk online crowdsourcing platform. Mixed-effects growth models revealed that pain severity and interference, emotional distress, and opioid misuse behaviors did not significantly deteriorate across one year during the pandemic. None of the socio-demographic factors, pain catastrophizing, or sleep disturbance moderated outcome trajectories. However, individuals with higher pain acceptance reported greater improvement in pain severity (P< .008, 95% CI: -.0002, -.00004) and depressive symptoms (P< .001, 95% CI: -.001, -.0004) over time. Our findings suggest that the negative impact of the pandemic on pain, emotional distress, and opioid misuse behaviors is quite small overall. The outcome trajectories were also stable across different socio-demographic factors, as well as individual differences in pain catastrophizing and sleep disturbance. Nevertheless, interventions that target improvement of pain acceptance may help individuals with chronic pain be resilient during the pandemic. PERSPECTIVE: Individuals with chronic pain overall did not experience significant exacerbation of pain, emotional distress, and opioid misuse across one year during the COVID-19 pandemic. Individuals with higher pain acceptance showed greater improvement in pain severity and depressive symptoms over time during the pandemic.

Profiles of Pain Acceptance and Values-Based Action in the Assessment and Treatment of Chronic Pain

Pain acceptance and values-based action are relevant to treatment outcomes in those with chronic pain. It is unclear if patterns of responding in these two behavioral processes can be used to classify patients into distinct classes at treatment onset and used to predict treatment response. This observational cohort study had two distinct goals. First, it sought to classify patients at assessment based on pain acceptance and values-based action (N = 1746). Second, it sought to examine treatment outcomes based on class membership in a sub-set of patients completing an interdisciplinary pain rehabilitation program of Acceptance and Commitment Therapy for chronic pain (N = 343). Latent profile analysis was used in the larger sample to identify three distinct patient classes: low acceptance and values-based (AV) action (Low AV; n = 424), moderate acceptance and values-based action (Moderate AV; n = 983) and high acceptance and values-based action (High AV; n = 339). In the smaller treated sample, participants in the Low AV and Moderate AV class demonstrated improvements across all outcome variables, whereas those in the High AV class did not. These findings support the role of pain acceptance and values-based action in those with chronic pain.

A Brief Psychological Intervention for Chronic Pain in Primary Care: Examining Long-term Effects from a Pilot Randomized Clinical Trial

BACKGROUND

Despite the existence of evidence-based psychological interventions for pain management, there are barriers that interfere with treatment engagement. A brief intervention integrated into primary care reduced barriers and showed promising benefits from pre- to post-intervention. However, it is unknown whether a brief intervention can provide long-term effects. The purpose of this study was to examine whether a brief psychological intervention offered benefits in pain severity, pain interference, pain catastrophizing, and depressive symptoms at 1- and 6-month follow-ups.

METHODS

The majority of participants who enrolled in a pilot randomized clinical trial of a 5-session psychological intervention for chronic pain in primary care completed the 1-month (n= 54; 90%) and 6-month follow-ups (n= 50; 83.3%). Participants completed measures of pain severity, pain interference, pain catastrophizing, and depressive symptoms.

RESULTS

From baseline to the 6-month follow-up, those in the intervention group had significantly better outcomes for pain severity (p= .01) and pain catastrophizing (p= .003) compared to the control group. There were no significant differences between the intervention and control groups for pain interference and depression. The percentage of patients in the intervention experiencing clinically significant improvement across all outcomes was higher than the control group.

CONCLUSIONS

Findings suggest that a brief psychological intervention for chronic pain in primary care may offer longer-term benefits similar to that of lengthier interventions. Future studies should examine this through a randomized clinical trial with a larger sample size.

Patient Experiences of Self-Management for Chronic Low Back Pain: A Qualitative Study

OBJECTIVE

Chronic low back pain (CLBP) is a lifelong condition causing disability and distress. One aim of treatment is to enhance self-management. To date, self-management interventions have had limited effectiveness. A greater understanding of self-management for CLBP has the potential to improve future interventional trials. The purpose of this study was to identify the experience of CLBP self-management for patients attending outpatient physical therapy and assess how the experience of CLBP self-management changes over time.

METHODS

This qualitative study used constructivist grounded theory. Patients with CLBP who were attending an outpatient physical therapy department were recruited using convenience sampling. Each participant attended a semistructured interview. These were audio recorded and transcribed verbatim. The data were coded and thematically analyzed by the lead researcher. Recruitment continued until data saturation. Participants reviewed preliminary themes for validation.

RESULTS

Six subthemes emerged from 9 interviews: (1) self-doubt, (2) coping day to day, (3) independent discovery, (4) developing resilience, (5) health care: opportunity and threat, and (6) living with pain differently. Two themes took on greatest significance. Self-doubt appeared most strongly and was prevalent in all experiences. However, living with pain differently appeared in those who had developed a level of pain acceptance. These themes formed a conceptual model, "Fluctuating Uncertainty."

CONCLUSION

The experience of CLBP self-management is one of fluctuating self-doubt. Self-doubt is the predominant experience and is characterized by the perception of pain as a threat and low pain self-efficacy. During times of greater clarity, individuals develop strategies that increase pain self-efficacy and reinforce the perception of pain without threat. These are features of learning to live well with pain.

IMPACT

CLBP is a lifelong condition requiring self-management. The current study characterizes the self-management strategies used by patients attending physical therapy. The fluctuating nature of these strategies is dependent upon perception of pain and pain self-efficacy.

LAY SUMMARY

People with CLBP who self-manage their pain fluctuate between attempting to control pain and learning to live with pain. People who understand their condition develop wider-ranging self-management strategies.

Exercise combined with Acceptance and Commitment Therapy compared with a standalone supervised exercise programme for adults with chronic pain: a randomised controlled trial

ABSTRACT

A prospective, 2-armed, parallel group randomised controlled trial (RCT) was conducted to compare the effectiveness of Acceptance and Commitment Therapy (ACT) combined with a supervised exercise programme with a supervised exercise programme alone for adults with chronic pain. One hundred seventy-five participants were individually randomised to receive either the combined Exercise and ACT (ExACT) intervention or supervised exercise alone. Those allocated to the ExACT group attended 8 weekly sessions with a psychologist based on the ACT approach, in addition to supervised exercise classes led by a physiotherapist. The control group attended weekly supervised exercise classes but did not take part in an ACT programme. Both groups were followed up postintervention and again after 12 weeks. The primary outcome was pain interference at 12-week follow-up. Estimates of treatment effects at follow-up were based on intention-to-treat analyses, implemented using a linear mixed-effects model. The findings of this RCT showed no difference in the effectiveness of ExACT, compared with a supervised exercise programme alone for the primary outcome pain interference at 12-week follow-up (mean difference -0.18, 95% confidence interval -0.84 to 0.48, P = 0.59, d = 0.11). ExACT group participants reported superior outcomes for pain self-efficacy, pain catastrophising, and committed action, compared with the control group, but there were no differences between the groups for other secondary outcomes or treatment process measures. Higher levels of treatment satisfaction and global impression of change were reported by ExACT group participants. Exercise combined with Acceptance and Commitment Therapy was not superior to a standalone supervised exercise programme for reducing pain interference in adults with chronic pain.

Increased gray matter following mindfulness-based stress reduction in breast cancer survivors with chronic neuropathic pain: preliminary evidence using voxel-based morphometry

PURPOSE

To investigate the impact of Mindfulness-Based Stress Reduction (MBSR) on gray matter volume (GMV) in female breast cancer survivors who suffer from chronic neuropathic pain (CNP).

METHODS

Voxel-based morphometry (VBM) was used to explore differences in GMV in 13 MBSR trainees and 10 waitlisted controls, with MRI scans and self-report measures completed pre- and post-8 weeks of training.

RESULTS

Compared to controls, the MBSR group had greater GMV in the angular gyrus and middle frontal gyrus post-training. The MBSR group's right parahippocampal gyrus GMV increased from pre- to post-training, whereas the control group's left parahippocampal gyrus, precuneus, middle temporal gyrus, and right cuneus GMV decreased over the same time period. Pain interference was significantly reduced and mindfulness was significantly increased following MBSR for the intervention group only.

CONCLUSIONS

MBSR was associated with increased GMV in regions where GMV is known to (1) increase with mindfulness and reorientation of attention and (2) decrease with the experience of chronic neuropathic pain. By contrast, the control group's decreases in GMV may be due to the negative effects of CNP which potentially may be reduced with MBSR, though further research is needed.

IMPLICATIONS FOR CANCER SURVIVORS

Given the poor efficiency of pharmacotherapies in a high percentage of women with neuropathic pain following breast cancer treatment, adjunct methods are required. MBSR may affect the brain to help alter attention and perception of pain, thus playing a potentially important role in the path to wellness for breast cancer survivors.

Mindful Walking in Patients with Chronic Low Back Pain: A Randomized Controlled Trial

Aim:

The objective of this study was to investigate the effectiveness of a mindful walking program (MWP) in patients with chronic low back pain (CLBP).

Methods:

The trial was a two-armed, randomized, controlled single-center open clinical trial. The study was performed in the Outpatient Clinic for Integrative Medicine of the Charité–Universitätsmedizin Berlin. The participants were adults aged 18–65 years with CLBP (≥3 months) and an average low back pain within the past 7 days measured on a visual analog scale (VAS, 0 = no pain, 100 = worst imaginable pain) of at least 40 mm. The patients received either eight weekly MWP sessions or no intervention (control). The primary outcome was the perceived pain intensity assessed with a VAS (0–100 mm) after 8 weeks. The secondary outcomes included back function assessed by the Hannover Functional Questionnaire Backache (FFbH-R) and perceived stress assessed by the 14-item Cohen's Perceived Stress Scale (PSS-14). The results were obtained by analysis of covariance adjusted for the respective baseline values.

Results:

In total, 55 patients were randomized (MWP: n = 29, 82.8% female, mean (±standard deviation) age: 52.5 ± 8.6 years, pain: 56.4 ± 14.1 mm; control: n = 26, 84.6% female, 54.8 ± 7.5 years, pain: 55.4 ± 13.1 mm). After 8 weeks, compared with the control conditions, the MWP was not associated with a statistically significant benefit for pain (VAS), adjusted mean − 9.6 [−22.3 to 3.1], p = 0.136, clinical benefits for back function (FFbH-R), adjusted mean 2.2 [−4.2 to 8.6], p = 0.493, or stress (PSS-14), adjusted mean − 1.6 [−4.8 to 1.6], p = 0.326.

Conclusion:

In conclusion, compared with no intervention, mindful walking did not significantly improve pain, back function, or perceived stress in patients with CLBP.

How do psychologically based interventions for chronic musculoskeletal pain work? A systematic review and meta-analysis of specific moderators and mediators of treatment

Psychologically based interventions aim to improve pain-related functioning by targeting pain-related fears, cognitions and behaviors. Mediation and moderation analyses permit further examination of the effect of treatment on an outcome. This systematic review and meta-analysis aims to synthetize the evidence of specific mediators and moderators (i.e., treatment targets) of psychologically based treatment effects on pain and disability. A total of 28 mediation and 11 moderation analyses were included. Thirteen mediation studies were included in a meta-analysis, and the rest was narratively synthetized. Reductions in pain-related fear (indirect effect [IE]: -0.07; 95% confidence interval [CI]: -0.11, -0.04) and catastrophizing (IE: -0.07; 95%CI: -0.14, -0.00), as well as increases in self-efficacy (IE: -0.07; 95%CI: -0.11, -0.04), mediated effects of cognitive behavioral therapy on disability but not on pain intensity, when compared to control treatments. Enhancing pain acceptance (IE: -0.17; 95%CI: -0.31, -0.03) and psychological flexibility (IE: -0.30; 95%CI: -0.41, -0.18) mediated acceptance and commitment therapy effects on disability. The narrative synthesis showed conflicting evidence, which did not support a robust moderated effect for any of the examined constructs. Overall, the methodological quality regarding mediation was low, and some key pitfalls are highlighted alongside recommendations to provide a platform for future research.

Multimodal Chronic Pain Therapy for Adults via Smartphone: Randomized Controlled Clinical Trial

BACKGROUND

Combination therapies delivered remotely via the internet or mobile devices are increasingly being used to improve and promote the self-management of chronic conditions. However, little is known regarding the long-term effects of these interventions.

OBJECTIVE

The aim of this study is to evaluate the effectiveness of a multimodal intervention program that measures associated variables such as catastrophizing, pain acceptance, and quality of life using a mobile device in people with chronic pain in an outpatient setting.

METHODS

A randomized controlled clinical trial was performed using parallel treatment groups. A total of 209 patients with chronic musculoskeletal pain were randomly assigned to one of the two study arms. The intervention group received a standard web-based psychosocial therapy-type program of activities through a smartphone for 6 weeks. The control group only had access to the Find out more section of the app, which contained audiovisual material for pain management based on a self-help approach. The primary outcome was catastrophizing measured using the Pain Catastrophizing Scale (PCS). Secondary outcomes were pain acceptance measured using the Chronic Pain Acceptance Questionnaire and health-related quality of life measured using the EuroQol Visual Analogue Scale. Assessments were conducted at baseline (T1), after treatment (T2), and at the 3-month follow-up (T3). The variations between the different phases were assessed using the percentage change rescaled with log base 2. The Cohen d was calculated based on the results of the linear mixed model. The investigators of the study who evaluated the results were not involved in patient recruitment and were blinded to the group assignment.

RESULTS

Positive effects were found in the intervention group (T2-T1) in catastrophizing between the baseline and posttreatment phases (P<.001) and in helplessness (-0.72 vs 0.1; P=.002), rumination (-1.59 vs -0.53; P<.001), acceptance (0.38 vs 0.05; P=.001), and quality of life (0.43 vs -0.01; P=.002), although no significant changes were found for magnification (0.2 vs 0.77; P=.14) and satisfaction with health (0.25 vs -0.27; P=.13). Three months after treatment, significant differences were observed in the intervention group for the outcome variable of catastrophizing (PCS; -0.59 vs 0.2; P=.006) and the PCS subscales of helplessness (-0.65 vs 0.01; P=.07), rumination (1.23 vs -0.59; P=.04), and magnification (0.1 vs 0.86; P=.02).

CONCLUSIONS

The results of our study suggest that app-based mobile multidimensional treatments for adults with chronic pain improve catastrophizing, quality of life, and psychological flexibility immediately after treatment and that the effects are maintained for the primary outcome of catastrophizing for at least 3 months following treatment. Moreover, they promote self-management and can be used to complement face-to-face pain treatments.

Interventions for Depressive Symptoms in People Living with Chronic Pain: A Systematic Review of Meta-Analyses

OBJECTIVE

This review investigated the effectiveness of clinical interventions on depressive symptoms in people with all types of chronic pain.

METHODS

We searched seven electronic databases and reference lists on September 15, 2020, and included English-language, systematic reviews and meta-analyses of trials that examined the effects of clinical interventions on depressive outcomes in chronic pain. Two independent reviewers screened, extracted, and assessed the risk of bias. PROSPERO registration: CRD42019131871.

RESULTS

Eighty-three reviews were selected and included 182 meta-analyses. Data were summarized visually and narratively using standardized mean differences with 95% confidence intervals as the primary outcome of interest. A large proportion of meta-analyses investigated fibromyalgia or mixed chronic pain, and psychological interventions were most commonly evaluated. Acceptance and commitment therapy for general chronic pain, and fluoxetine and web-based psychotherapy for fibromyalgia showed the most robust effects and can be prioritized for implementation in clinical practice. Exercise for arthritis, pharmacotherapy for neuropathic pain, self-regulatory psychotherapy for axial pain, and music therapy for general chronic pain showed large, significant effects, but estimates were derived from low- or critically low-quality reviews.

CONCLUSIONS

No single intervention type demonstrated substantial superiority across multiple pain populations. Other dimensions beyond efficacy, such as accessibility, safety, cost, patient preference, and efficacy for non-depressive outcomes should also be weighed when considering treatment options. Further effectiveness research is required for common pain types such as arthritis and axial pain, and common interventions such as opioids, anti-inflammatories and acupuncture.
