Psychological therapies for the management of chronic neuropathic pain in adults

Mechanisms of pain in aging and age-related conditions: Focus on caregivers

Pain is a complex, subjective experience that can significantly impact quality of life, particularly in aging individuals, by adversely affecting physical and emotional well-being. Whereas acute pain usually serves a protective function, chronic pain is a persistent pathological condition that contributes to functional deficits, cognitive decline, and emotional disturbances in the elderly. Despite substantial progress that has been made in characterizing age-related changes in pain, complete mechanistic details of pain processing mechanisms in the aging patient remain unknown. Pain is particularly under-recognized and under-managed in the elderly, especially among patients with Alzheimer's disease (AD), Alzheimer's disease-related dementias (ADRD), and other age-related conditions. Furthermore, difficulties in assessing pain in patients with AD/ADRD and other age-related conditions may contribute to the familial caregiver burden. The purpose of this article is to discuss the mechanisms and risk factors for chronic pain development and persistence, with a particular focus on age-related changes. Our article also highlights the importance of caregivers working with aging chronic pain patients, and emphasizes the urgent need for increased legislative awareness and improved pain management in these populations to substantially alleviate caregiver burden.

The development of the Therapeutic Group Context Questionnaire: Reliability and validity measures based on telehealth Group-based Pain Management Programs

INTRODUCTION

In 2016, the Centers for Disease Control and Prevention analyzed the National Health Interview Survey data and found that the occurrence of chronic pain and high-impact chronic pain in the USA was 20.4% and 8%, respectively. Group-based Pain Management Programs have been viewed as significant treatments aiding patients with self-management of chronic pain. The onset of coronavirus disease 2019 (COVID-19) at the beginning of 2020, widely eliminated the in-person Group-based Pain Management Programs. The exploration of therapeutic contextual factors such as the therapeutic alliance and group dynamics in telehealth Group-based Pain Management Programs appears warranted for which reason the Therapeutic Group Context Questionnaire was developed.

METHODS

The therapeutic alliance and group dynamics items in the Therapeutic Group Context Questionnaire were developed from an extensive literature review and underwent examination of content validity, internal consistency, reliability, and validity through telehealth Group-based Pain Management Programs.

RESULTS

Content validity of the Therapeutic Group Context Questionnaire was established in five separate stages and the psychometrics of the Therapeutic Group Context Questionnaire was found to be very good with high internal consistency and reliability (r = 0.85-0.97) and the ability of the Therapeutic Group Context Questionnaire to differentiate between high and low scorers on the SF-36 emotional well-being measure.

DISCUSSION

The examination of therapeutic contextual factors via telehealth Group-based Pain Management Programs using the Therapeutic Group Context Questionnaire appears possible in view of the very good psychometric properties described above. Investigation of therapeutic contextual factors through the Therapeutic Group Context Questionnaire may provide greater insight into the role that these factors may have in telehealth programs and their impact on pain outcomes. Future investigation of the Therapeutic Group Context Questionnaire in non-telehealth Group-based Pain Management Programs, as well as, other disorders being addressed via telehealth appears warranted.

Chronic Pain and High Impact Chronic Pain in Children and Adolescents: A Cross-Sectional Study

The aims of this study were to: 1) estimate the prevalence of chronic pain (CP) and high impact chronic pain (HICP) in a community sample of children and adolescents; and 2) compare groups (those without CP, those with CP but no HICP, and those with HICP) with respect to demographic variables, pain variables, and physical, psychological, and school-related function. One thousand one hundred and fifteen children and adolescents participated (56% girls; age: ߂ = 11.67; SD = 2.47; range = 8-18 years). The prevalence of CP and HICP was 46% and 5%, respectively, and was higher in girls and increased with age. Participants with HICP reported greater pain intensity and higher pain frequency than those with CP but no HICP. In addition, participants with HICP reported lower mobility, greater fatigue, worst sleep quality, more anxiety and depression symptoms, worst cognitive function, missing more school days, and worse perceived school performance. HICP is a prevalent condition in children and adolescents and is associated with many negative consequences. Stakeholders must be aware of this and ensure that treatment programs are available to reduce the individual and societal impact of HICP in young individuals. PERSPECTIVE: This article provides information on CP and HICP prevalence and impact in children and adolescents. By better understanding the nature and score of these conditions, we will be able to develop more effective early interventions to help this population and thereby reduce their long-term negative impact.

Preliminary study: quantification of chronic pain from physiological data

Supplemental Digital Content is Available in the Text.

Preliminary evidence suggests that physiological variables collected with our low-cost pain meter are correlated with chronic pain, both for individuals and populations.

Introduction:

It is unknown if physiological changes associated with chronic pain could be measured with inexpensive physiological sensors. Recently, acute pain and laboratory-induced pain have been quantified with physiological sensors.

Objectives:

To investigate the extent to which chronic pain can be quantified with physiological sensors.

Methods:

Data were collected from chronic pain sufferers who subjectively rated their pain on a 0 to 10 visual analogue scale, using our recently developed pain meter. Physiological variables, including pulse, temperature, and motion signals, were measured at head, neck, wrist, and finger with multiple sensors. To quantify pain, features were first extracted from 10-second windows. Linear models with recursive feature elimination were fit for each subject. A random forest regression model was used for pain score prediction for the population-level model.

Results:

Predictive performance was assessed using leave-one-recording-out cross-validation and nonparametric permutation testing. For individual-level models, 5 of 12 subjects yielded intraclass correlation coefficients between actual and predicted pain scores of 0.46 to 0.75. For the population-level model, the random forest method yielded an intraclass correlation coefficient of 0.58. Bland–Altman analysis shows that our model tends to overestimate the lower end of the pain scores and underestimate the higher end.

Conclusion:

This is the first demonstration that physiological data can be correlated with chronic pain, both for individuals and populations. Further research and more extensive data will be required to assess whether this approach could be used as a “chronic pain meter” to assess the level of chronic pain in patients.

The missing mechanistic link: Improving behavioral treatment efficacy for pediatric chronic pain

Pediatric chronic pain is a significant global issue, with biopsychosocial factors contributing to the complexity of the condition. Studies have explored behavioral treatments for pediatric chronic pain, but these treatments have mixed efficacy for improving functional and psychological outcomes. Furthermore, the literature lacks an understanding of the biobehavioral mechanisms contributing to pediatric chronic pain treatment response. In this mini review, we focus on how neuroimaging has been used to identify biobehavioral mechanisms of different conditions and how this modality can be used in mechanistic clinical trials to identify markers of treatment response for pediatric chronic pain. We propose that mechanistic clinical trials, utilizing neuroimaging, are warranted to investigate how to optimize the efficacy of behavioral treatments for pediatric chronic pain patients across pain types and ages.

Effectiveness of a Fibromyalgia Online Nursing Consultation in the Quality of Life: A Randomized Controlled Trial

BACKGROUND

Aim: To evaluate the effectiveness of an online nursing consultation through the Internet platform Red Sinapsis (RS) in improving the perceived quality of life of patients with fibromyalgia (FM).

METHOD

Eighty patients with FM were randomized to an intervention group (n = 40) or control group (n= 40). The intervention group (IG) was monitored by a nursing specialist through the online platform RS while the control group (CG) received standard follow-up at the clinic. The Fibromyalgia Impact Questionnaire (FIQ) and 36-item Short-Form Health Survey (SF-36) were used at baseline, 6-month, and 12-month follow-up.

RESULTS

The IG showed a 65% improvement in the perception of their general state of health at 12 months into the study, compared with an improvement of 5.6% in the CG (p < .001). The IG also achieved better results for emotional status, with a maintained improvement throughout the study of more than 2 points in the anxiety variable (from 7.64 to 5.36), that remained constant in the CG. The depression variable also showed constant improvement over the 12 months of the study in the IG, rising from an average of 7.72 (standard deviation [SD] = 2.05) to 5.33 (SD = 1.65), while in the CG a slight deterioration was observed. In both cases, the difference in mood evolution was significant (p < .001).

CONCLUSIONS

Online nursing follow-up for people with fibromyalgia improves patients' perceived quality of life related to their welfare and emotional state. Fibromyalgia (FM) is among the diseases causing the highest rate of occupational disability in Spain. Fibromyalgia (FM) is a complex condition that causes pain, fatigue, non-refreshed sleep, mood disturbance and cognitive impairment.

Opioid tapering support using a web-based app: Development and protocol for a pilot randomized controlled trial

BACKGROUND

Given limited efficacy and potential harms of long-term opioid therapy, it is patient-centered and guideline-concordant to offer patients the opportunity to engage in a supportive, patient-centered tapering program. The goal of this study was to develop and pilot an interactive web-based program designed to support patients willing to consider an opioid taper; this manuscript describes the development and the protocol for a pilot randomized trial of Summit.

METHODS

We used intervention mapping to develop the Summit program; during the development period we engaged multiple stakeholder groups and conducted usability testing to refine the interactive, theory-informed, multi-component mobile website program which includes education, video testimonials, self-management skills, and access to a peer specialist. We will evaluate the Summit program in a two-arm, 9 month randomized-controlled trial where 64 individuals will be assigned either to the Summit program or to a control group (pain tracking app). As a pilot trial, the primary outcomes are feasibility and acceptability; we will also measure patient-reported outcomes related to pain, quality of life, and opioid use.

IMPLICATIONS

We developed an interactive program; results of the pilot trial are pending. If shown to be effective, Summit would be useful both in augmenting care for patients who are engaged in a taper with primary care.

Online ACT intervention for fibromyalgia: An exploratory study of feasibility and preliminary effectiveness with smartphone-delivered experiential sampling assessment

INTRODUCTION

Acceptance and commitment therapy (ACT) is an effective treatment for chronic pain conditions. ACT seeks to produce clinical change by enhancing Psychological Flexibility (PF). This exploratory (feasibility and preliminary effectiveness) study presents a pilot application of an online ACT group intervention for fibromyalgia (FM) with an extensive Experiential Sampling (ES) assessment of outcome and process variables via smartphone.

METHOD

5-weekly ACT online group sessions were applied to 9 female FM patients. Questionnaire-based assessments of several clinical outcomes and PF processes were conducted pre- and post-intervention, and at 6-month follow-up. Extensive (6 weeks pre- and 6 weeks post-intervention) smartphone-delivered ES was implemented to gather process and outcome data in the patients' usual contexts. Clinically significant change was evaluated both at the group level and individually.

RESULTS

This treatment format appears to be feasible and acceptable to participants, with good adoption and completion rates (75 %) and excellent rates of treatment completion and clinical adherence (100 %). Participants showed significant reductions in affective pain, distress and biopsychosocial impact of FM both post-intervention and at 6-month follow-up (as measured with questionnaires), as well as significant improvements in satisfaction with actions and emotional discomfort (as measured through ES). Multilevel regression analyses indicated that PF-related processes assessed through ES had a significant impact on clinical outcomes and predicted the impact of FM at the 6-month follow-up.

CONCLUSIONS

A brief online group ACT intervention for FM was both feasible and acceptable to participants. Also, there was preliminary evidence of effectiveness in enhancing pain-related PF and producing clinical benefits in FM.

Tailored internet-based cognitive behavioral therapy for individuals with chronic pain and comorbid psychological distress: a randomized controlled trial

Comorbid psychological problems are commonly related to chronic pain but addressing heterogeneous comorbidities in traditional settings is often difficult. Delivering individually tailored treatment using the internet could be a viable alternative. The present study investigates whether a guided, individually tailored and internet-delivered cognitive behavioral therapy (ICBT) could improve mood and reduce disability in individuals suffering from chronic pain and comorbid psychological distress.Participants were recruited from a pain clinic and randomized to either ICBT or waiting list. The participants (n = 187) individually tailored treatments included 6-13 modules targeting different types of psychological distress. Modules were designed to be completed weekly, and feedback was provided by clinicians. Participants completed an average of 5.1 (49.7%) modules, with 22.9% completing all assigned modules. Intention-to-treat analyses showed significantly larger improvements in depression, disability, pain acceptance, catastrophizing, and quality of life in the ICBT-group compared to the control group. Between-group effect sizes were very small or small at post for the primary outcomes depression (d = 0.18) and pain interference (d = 0.22). Other effect sizes ranged from very small to small, with the largest effect being improvements in pain acceptance (d = 0.3). All significant changes were stable at 12-month follow up.

Internet-delivered cognitive and behavioural based interventions for adults with chronic pain: a systematic review and meta-analysis of randomized controlled trials

ABSTRACT

This study examined the efficacy of Internet-delivered cognitive and behavioural interventions for adults with chronic pain, and explored the role of clinical and study characteristics as moderators of treatment effects. PubMed, Embase, PsycINFO, and CENTRAL and CINAHL were searched to identify randomised controlled trials published up to October 2021. A meta-analysis of 36 studies (5778 participants) was conducted, which found small effect sizes for interference/disability (Hedges' g = 0.28; 95% CI 0.21, 0.35), depression (g = 0.43; 95% CI 0.33, 0.54), anxiety (g = 0.32; 95% CI 0.24, 0.40), pain intensity (g = 0.27; 95% CI 0.21, 0.33), self-efficacy (g = 0.39; 95% CI 0.27, 0.52) and pain catastrophizing (g = 0.31; 95% CI 0.22, 0.39). Moderator analyses found interventions which involved clinician guidance had significantly greater effect sizes for interference/disability (g = 0.38), anxiety (g = 0.39), and pain intensity (g = 0.33) compared to those without (g = 0.16, g = 0.18; g = 0.20, respectively). Studies using an inactive control had greater effects for depression (g = 0.46) compared to active control trials (g = 0.22). No differences were found between treatments based on traditional Cognitive Behaviour Therapy versus Acceptance and Commitment Therapy. Sample size, study year, and overall risk of bias (Cochrane rating) did not consistently moderate treatment effects. Overall, the results support the use of internet-delivered cognitive and behavioural interventions as efficacious and suggest guided interventions are associated with greater clinical gains for several key pain management outcomes.Prospectively registered on OSF Registries (citation: osf.io/cvq3j/).

Exposure in Vivo as a Treatment Approach to Target Pain-Related Fear: Theory and New Insights From Research and Clinical Practice

Pain-related fear (PRF) can be a significant factor contributing to the development and maintenance of pain-related disability in individuals with persistent pain. One treatment approach to target PRF and related avoidance behavior is exposure in vivo (EXP). EXP has a long history in the field of anxiety, a field that is constantly evolving. This Perspective outlines recent theoretical advancements and how they apply to EXP for PRF, including suggestions for how to optimize inhibitory learning during EXP; reviews mechanistic work from neuroimaging supporting the targeting of PRF in people with chronic pain; and focuses on clinical applications of EXP for PRF, as EXP is moving into new directions regarding who is receiving EXP (eg, EXP in chronic secondary pain) and how treatment is provided (EXP in primary care with a crucial role for physical therapists). Considerations are provided regarding challenges, remaining questions, and promising future perspectives.

IMPACT

For patients with chronic pain who have elevated pain-related fear (PRF), exposure is the treatment of choice. This Perspective highlights the inhibitory learning approach, summarizes mechanistic work from experimental psychology and neuroimaging regarding PRF in chronic pain, and describes possible clinical applications of EXP in chronic secondary pain as well as in primary care.

eHealth Interventions to Support Self-Management in People With Musculoskeletal Disorders, "eHealth: It's TIME"-A Scoping Review

OBJECTIVE

eHealth-mediated interventions have been proposed as one option to support self-management in those with musculoskeletal disorders (MSDs). This scoping review aimed to chart the evidence regarding eHealth modalities, musculoskeletal diagnosis, and outcomes of eHealth-mediated self-management support interventions in persons with MSDs and identify any gaps within the literature.

METHODS

Six electronic databases (MEDLINE, CINAHL, PsycINFO, Embase, Scopus, and the Cochrane Database of Systematic Reviews), 7 grey literature sources (eg, OpenGrey), and reference and citation lists of included studies were searched from database inception to July 2020. Published studies of adult participants with a MSD utilizing an eHealth intervention to support self-management were included. Studies were limited to those published in English. Two reviewers independently screened all studies. Data were extracted by 1 reviewer and reviewed by another reviewer.

RESULTS

After screening 3377 titles and abstracts followed by 176 full texts, 87 studies fulfilled the eligibility criteria. The majority were published in the last 5 years (n = 48; 55%), with almost one-third originating in the United States (n = 28; 32%). The most common eHealth modality type was internet based (n = 22; 35%), with almost one-half (n = 41; 47%) of the included studies involving participants with widespread musculoskeletal symptoms. The most commonly reported outcomes were related to body functions (ie, pain intensity) (n = 67; 45%), closely followed by activities and participation (ie, function) (n = 65; 44%), with environmental factors (ie, health care utilization) the least commonly reported (n = 17; 20%).

CONCLUSIONS

There is considerable variation within the eHealth-mediated self-management support intervention literature. Research is needed on the role of eHealth-mediated self-management support interventions across a broad range of MSDs to guide clinical practice.

IMPACT

This scoping review has identified gaps in the literature relating to specific eHealth modalities, musculoskeletal diagnoses, and health care utilization data, which should guide future research.

OUP accepted manuscript

Objectives

Societal and health system pressures associated with the coronavirus disease 2019 (COVID-19) pandemic exacerbated the burden of chronic pain and limited access to pain management services for many. Online multidisciplinary pain programs offer an effective and scalable treatment option, but have not been evaluated within the context of COVID-19. This study aimed to investigate the uptake and effectiveness of the Reboot Online chronic pain program before and during the first year of the COVID-19 pandemic.

Methods

Retrospective cohort analyses were conducted on routine service users of the Reboot Online program, comparing those who commenced the program during the COVID-19 pandemic (March 2020–March 2021), to those prior to the pandemic (April 2017–March 2020). Outcomes included the number of course registrations; commencements; completion rates; and measures of pain severity, interference, self-efficacy, pain-related disability, and distress.

Results

Data from 2,585 course users were included (n = 1138 pre-COVID-19 and n = 1,447 during-COVID-19). There was a 287% increase in monthly course registrations during COVID-19, relative to previously. Users were younger, and more likely to reside in a metropolitan area during COVID-19, but initial symptom severity was comparable. Course adherence and effectiveness were similar before and during COVID-19, with moderate effect size improvements in clinical outcomes post-treatment (g = 0.23–0.55).

Discussion

Uptake of an online chronic pain management program substantially increased during the COVID-19 pandemic. Program adherence and effectiveness were similar pre- and during-COVID. These findings support the effectiveness and scalability of online chronic pain management programs to meet increasing demand.

The No Worries Trial: Efficacy of Online Dialectical Behaviour Therapy Skills Training for Chronic Pain (iDBT-Pain) Using A Single Case Experimental Design

Emotion dysregulation frequently co-occurs with chronic pain, which in turn leads to heightened emotional and physical suffering. This cycle of association has prompted a recommendation for psychological treatment of chronic pain to target mechanisms for emotion regulation. The current trial addressed this need by investigating a new internet-delivered treatment incorporating emotional skills training from dialectical behavioural therapy (DBT). Using a single-case experimental design that is suited to heterogeneous populations and can demonstrate efficacy with a small sample, three participants with chronic pain were recruited. Participants received four weeks of online DBT skills training (iDBT-Pain intervention) which incorporated one-on-one sessions over Zoom and a web app. Results revealed compelling evidence for the intervention on the primary outcome of emotion dysregulation and were promising for the secondary outcome of pain intensity. Improvement was also identified on pre-and post-measures of depression, coping behaviours, sleep problems, wellbeing, and harm avoidance, indicating that the intervention may positively influence other factors related to chronic pain. Overall, the trial provides preliminary efficacy for the intervention to improve chronic pain. However, we recommend further investigation of the iDBT-Pain intervention, either in single case trials, which when conducted with scientific rigour may be aggregated to derive nomothetic conclusions, or in a group-comparison trial to compare with usual modes of treatment. Perspective: This trial advances understanding of emotion-focused treatment for chronic pain and provides evidence for a viable new technological treatment. Importantly, as an internet-delivered approach, the iDBT-Pain intervention is accessible to those with restricted mobility and remote communities where there are often limited psychological services for people with chronic pain. Trial registration: The trial was registered on the Australian and New Zealand Clinical Trials Registry (ACTRN12620000604909).

The Pain Course: a randomised controlled trial and economic evaluation of an internet-delivered pain management program

ABSTRACT

There is interest in the potential of Internet-delivered programs to cost-effectively increase access to pain management for people with chronic pain. However, few large-scale clinical and economic evaluations have been undertaken. Using a randomised controlled trial design, the current study (n = 659) examined the clinical efficacy, cost-effectiveness, and cost utility of an Internet-delivered pain management program for people with mixed chronic pain conditions when delivered with optional clinician support. The treatment group reported significant improvements in disability, depression, anxiety, average pain intensity, and quality-adjusted life years (QALYs), compared with control, and exhibited relatively high levels of treatment engagement and satisfaction. Each additional clinical improvement (defined as ≥ 30% improvement) produced by the intervention, over control, was associated with a cost of $48, $27, $38, and $83 for disability, depression, anxiety, and average pain intensity, respectively. Gaining one QALY was associated with a cost of $152 or $11,910 per QALY when an 80% probability criterion for cost utility was applied. The program itself was associated a relatively small, fixed, cost per patient but was not cost saving over the brief intervention period. The findings support the clinical efficacy and cost-effectiveness of Internet-delivered programs with "on demand" clinician support as a way to increase access to pain management. Key limitations of the current study include the use of a waitlist-control group, a short follow-up period, and the focus on governmental healthcare costs. Further evaluation of these programs is necessary if they are scaled up and offered as routine care.

Self-Guided Web-Based Pain Education for People With Musculoskeletal Pain: A Systematic Review and Meta-Analysis

OBJECTIVE

The purpose of this study was to investigate the effectiveness of web-based pain education programs without clinical support in patients with musculoskeletal pain.

METHODS

PubMed, Scopus, CINAHL, Web of Science, Cochrane Library, and PsycINFO were searched from inception to February 2020. Included studies were randomized clinical trials in which people with musculoskeletal pain were allocated to an experimental group that received web-based pain education as a standalone approach. Three review authors performed data extraction. The PEDro (Physiotherapy Evidence Database) scale was used to assess the methodological quality of the studies. The primary outcomes were pain intensity and disability.

RESULTS

Six trials with a total of 1664 participants were included. There is moderate-quality evidence with a small effect size that web-based pain education programs, as a standalone approach, are better than minimal intervention (no intervention or booklets) for pain intensity (standardized mean difference [SMD] = -0.23; 95% CI = -0.43 to -0.04) in the short term and intermediate term (SMD = -0.26; 95% CI = -0.42 to -0.10). Regarding disability, there is low-quality evidence that web-based pain education programs are better than minimal intervention (SMD = -0.36; 95% CI = -0.64 to -0.07) in the short term. Web-based pain education added to usual care was no better than usual care alone in the intermediate or long term for primary outcomes.

CONCLUSIONS

Web-based pain education for adults with musculoskeletal pain, as a standalone approach, was better than minimal intervention for pain intensity and disability in the short term, and for pain intensity in the intermediate term. Web-based pain education added to usual care did not provide additional benefits for primary outcomes in the intermediate or long term.

IMPACT

Web-based pain education as a standalone intervention provided small improvements in pain intensity and disability in patients with chronic musculoskeletal pain. Poorly resourced settings and overburdened health systems should consider this delivery method in the management of chronic musculoskeletal pain.

LAY SUMMARY

If you have chronic musculoskeletal pain, your physical therapist might recommend web-based pain education as treatment to help you reduce pain intensity and disability.

Self-help interventions for young people with persistent physical symptoms: A systematic review

OBJECTIVE

Persistent physical symptoms are frequent among young people causing considerable social, psychological, and economic consequences. Easily accessible interventions adapted to non-specialized settings are needed. We aimed to systematically review randomized controlled trials on self-help interventions for young people with persistent physical symptoms compared to active or passive control groups. Our purpose was to 1) describe applied therapeutic approaches and content and 2) examine potential effects on symptom burden and psychosocial outcomes.

METHODS

We included randomized controlled trials on minimal contact self-help interventions for young people with persistent physical symptoms. Systematic literature searches in PubMed, Cochrane Central, Embase, and PsycINFO were conducted. Study selection, data extraction and quality assessment were performed independently by two reviewers. A narrative synthesis of the effects was performed.

RESULTS

We identified 11 studies on self-help interventions for young people. The methodological quality of the studies was generally low. Participants suffered from impairing fatigue, headache, abdominal pain, and musculoskeletal or multi-site pain. Applied therapeutic approaches were cognitive behavioral therapy, relaxation training, hypnotherapy, and written self-disclosure. Outcomes were diverse and mainly related to symptom burden, whereas psychosocial outcomes were only sporadically examined. Overall, evidence of effectiveness of self-help interventions in alleviating symptom burden was weak, and potential effects could not be linked to one specific theoretical approach.

CONCLUSION

Few self-help interventions of diverse content exist for young people with persistent physical symptoms. Rigorously designed studies that include recommended outcome domains assessed by aligned measures are needed to determine and compare the clinical value of such interventions.

Comparative efficacy and safety of stimulant-type medications for depression: A systematic review and network meta-analysis

BACKGROUND

Globally, depression impacts nearly 300 million people, and roughly half do not achieve remission with standard first-line therapies. For such individuals, augmentation strategies are often helpful at reducing the severity of depression. While there are many potential adjunctive medication choices, psychostimulants are among the more controversial options.

OBJECTIVES

The present review sought to clarify the comparative efficacy and safety of different stimulant-like medications to treat depression.

METHODS

We conducted a systematic review and network meta-analysis of randomized, controlled trials (RCTs) using psychostimulant medications to treat adults with depression. Outcomes were pooled using rate ratios (RRs) for dichotomous outcomes (e.g., response, adverse events) and standardized mean differences (SMDs) for continuous outcomes (e.g., change in depression scores).

RESULTS

We identified 37 eligible studies (ranging from 1958 to 2016). We assessed nine psychostimulants: methylphenidate (n=14), dextroamphetamine (n=9), modafinil (n=6), lisdexamphetamine (n=3), methylamphetamine (n=3), pemoline (n=2), atomoxetine (n=1), desipramine (n=1), and imipramine (n=1). Overall, psychostimulants demonstrated efficacy for depression, reduced fatigue and sleepiness, and appeared well-tolerated. However, there was inconsistent evidence across particular psychostimulants. For example, the only psychostimulant which demonstrated efficacy for depression-in terms of both symptom severity and response rates-was methylphenidate.

CONCLUSIONS

While our review suggests that some psychostimulants-particularly methylphenidate-appear well-tolerated and demonstrate some efficacy for depression, as well as fatigue and sleepiness, the strength of evidence in our estimates was low to very low for most agents given the small sample sizes, few RCTs, and imprecision in most estimates. A lack of consistent evidence precludes a definitive hierarchy of treatments and points to a need for additional, high-quality RCTs.

Chronic non-cancer pain in adolescents: a narrative review

Introduction

Chronic pain is defined as a pain lasting more than 3–6 months. It is estimated that 25% of the pediatric population may experience some kind of pain in this context. Adolescence, corresponding to a particular period of development, seems to present the ideal territory for the appearance of maladaptive mechanisms that can trigger episodes of persistent or recurrent pain.

Methods

A narrative review, in the PubMed/Medline database, in order to synthetize the available evidence in the approach to chronic pain in adolescents, highlighting its etiology, pathophysiology, diagnosis, and treatment.

Results

Pain is seen as a result from the interaction of biological, psychological, individual, social, and environmental factors. Headache, abdominal pain, and musculoskeletal pain are frequent causes of chronic pain in adolescents. Pain not only has implications on adolescents, but also on family, society, and how they interact. It has implications on daily activities, physical capacity, school performance, and sleep, and is associated with psychiatric comorbidities, such as anxiety and depression. The therapeutic approach of pain must be multimodal and multidisciplinary, involving adolescents, their families, and environment, using pharmacological and non-pharmacological strategies.

Discussion and conclusion

The acknowledgment, prevention, diagnosis, and treatment of chronic pain in adolescent patients seem not to be ideal. The development of evidence-based forms of treatment, and the training of health professionals at all levels of care are essential for the diagnosis, treatment, and early referral of these patients.

Improving Outpatient Management of Patients On Chronic Opioid Therapy

Managing patients with chronic pain on chronic opioid therapy (COT) can be challenging if done mainly by an individual clinician. A stepwise, systematic approach to managing patients on COT includes centering the discussion around safety for the patient. Treatment agreements and monitoring plans are important to safe prescribing. With a team-based care approach programs can be implemented, which optimize the benefits of opioid therapy and mitigate the risk. In these settings COT can be prescribed adhering to current guidelines in order to help achieve pain management, optimize function, and advance the patients' quality of life goals.

Randomized clinical trial of Fibromyalgia Integrative Training (FIT teens) for adolescents with juvenile fibromyalgia - Study design and protocol

OBJECTIVE

Juvenile-onset fibromyalgia (JFM) is a chronic debilitating pain condition that negatively impacts physical, social and academic functioning. Cognitive-behavioral therapy (CBT) is beneficial in reducing functional disability among adolescents with JFM but has only a modest impact on pain reduction and does not improve physical exercise participation. This randomized controlled trial (RCT) aims to test whether a novel intervention that combines CBT with specialized neuromuscular exercise training (the Fibromyalgia Integrative Training program for Teens "FIT Teens") is superior to CBT alone or a graded aerobic exercise (GAE) program.

DESIGN/METHODS

This 3-arm multi-site RCT will examine the efficacy of the FIT Teens intervention in reducing functional disability (primary outcome) and pain intensity (secondary outcome), relative to CBT or GAE. All interventions are 8-weeks (16 sessions) in duration and are delivered in small groups of 4-6 adolescents with JFM. A total of 420 participants are anticipated to be enrolled across seven sites with approximately equal allocation to each treatment arm. Functional disability and average pain intensity in the past week will be assessed at baseline, post-treatment and at 3-, 6-, 9- and 12-month follow-up. The 3-month follow-up is the primary endpoint to evaluate treatment efficacy; longitudinal assessments will determine maintenance of treatment gains. Changes in coping, fear of movement, biomechanical changes and physical fitness will also be evaluated.

CONCLUSIONS

This multi-site RCT is designed to evaluate whether the combined FIT Teens intervention will have significantly greater effects on disability and pain reduction than CBT or GAE alone for youth with JFM. Clinical trials.gov registration: NCT03268421.

Comparative Efficacy and Acceptability of Psychotherapies for Self-harm and Suicidal Behavior Among Children and Adolescents: A Systematic Review and Network Meta-analysis

IMPORTANCE

Self-harm and suicidal behavior are associated with substantial morbidity and mortality among children and adolescents. The comparative performance of psychotherapies for suicidality is unclear because few head-to-head clinical trials have been conducted.

OBJECTIVE

To compare the efficacy of psychotherapies for the treatment of self-harm and suicidality among children and adolescents.

DATA SOURCES

Four major bibliographic databases (PubMed, MEDLINE, PsycINFO, and Embase) were searched for clinical trials comparing psychotherapy with control conditions from inception to September 2020.

STUDY SELECTION

Randomized clinical trials comparing psychotherapies for suicidality and/or self-harm with control conditions among children and adolescents were included after a blinded review by 3 independent reviewers (A.B., M.P., and J.W.).

DATA EXTRACTION AND SYNTHESIS

The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline was followed for data abstraction, and the Cochrane risk of bias tool was used to evaluate study-level risk of bias. Data abstraction was performed by 1 reviewer (A.B.) and confirmed by 2 independent blinded reviewers (J.W. and M.P.). Data were analyzed from October 15, 2020, to February 15, 2021.

MAIN OUTCOMES AND MEASURES

The primary outcomes were dichotomized self-harm and retention in treatment. The secondary outcomes were dichotomized all-cause treatment discontinuation and scores on instruments measuring suicidal ideation and depressive symptoms. Effect sizes were pooled using frequentist random-effects network meta-analysis models to generate summary odds ratios (ORs) and Cohen d standardized mean differences (SMDs). Negative Cohen d SMDs or ORs less than 1 indicated that the treatment reduced the parameter of interest relative to the control condition (eg, signifying a beneficial association with suicidal ideation).

RESULTS

The systematic search generated 1272 unique records. Of those, 44 randomized clinical trials (5406 total participants; 4109 female participants [76.0%]) from 49 articles were selected (5 follow-up studies were merged with their primary clinical trials to avoid publication bias). The selected clinical trials spanned January 1, 1995, to December 31, 2020. The median duration of treatment was 3 months (range, 0.25-12.00 months), and the median follow-up period was 12 months (range, 1-36 months). None of the investigated psychotherapies were associated with increases in study withdrawals or improvements in retention in treatment compared with treatment as usual. Dialectical behavioral therapies were associated with reductions in self-harm (OR, 0.28; 95% CI, 0.12-0.64) and suicidal ideation (Cohen d SMD, -0.71; 95% CI, -1.19 to -0.23) at the end of treatment, while mentalization-based therapies were associated with decreases in self-harm (OR, 0.38; 95% CI, 0.15-0.97) and suicidal ideation (Cohen d SMD, -1.22; 95% CI, -2.18 to -0.26) at the end of follow-up. The quality of evidence was downgraded because of high risk of bias overall, heterogeneity, publication bias, inconsistency, and imprecision.

CONCLUSIONS AND RELEVANCE

Although some psychotherapeutic modalities appear to be acceptable and efficacious for reducing self-harm and suicidality among children and adolescents, methodological issues and high risk of bias prevent a consistent estimate of their comparative performance.

Clinical and cost-effectiveness of an online-delivered group-based pain management programme in improving pain-related disability for people with persistent pain-protocol for a non-inferiority randomised controlled trial (iSelf-help trial)

INTRODUCTION

Persistent non-cancer pain affects one in five adults and is more common in Māori-the Indigenous population of New Zealand (NZ), adults over 65 years, and people living in areas of high deprivation. Despite the evidence supporting multidisciplinary pain management programmes (PMPs), access to PMPs is poor due to long waiting lists. Although online-delivered PMPs enhance access, none have been codesigned with patients or compared with group-based, in-person PMPs. This non-inferiority trial aims to evaluate the clinical and cost-effectiveness of a cocreated, culturally appropriate, online-delivered PMP (iSelf-help) compared with in-person PMP in reducing pain-related disability.

METHODS AND ANALYSIS

Mixed-methods, using a modified participatory action research (PAR) framework, involving three phases. Phase I involved cocreation and cultural appropriateness of iSelf-help by PAR team members. Phase II: The proposed iSelf-help trial is a pragmatic, multicentred, assessor-blinded, two-arm, parallel group, non-inferiority randomised controlled trial. Adults (n=180, age ≥18 years) with persistent non-cancer pain eligible for a PMP will be recruited and block randomised (with equal probabilities) to intervention (iSelf-help) and control groups (in-person PMP). The iSelf-help participants will participate in two 60-minute video-conferencing sessions weekly for 12 weeks with access to cocreated resources via smartphone application and a password-protected website. The control participants will receive group-based, in-person delivered PMP. Primary outcome is pain-related disability assessed via modified Roland Morris Disability Questionnaire at 6 months post intervention. Secondary outcomes include anxiety, depression, stress, pain severity, quality of life, acceptance, self-efficacy, catastrophising and fear avoidance. Data will be collected at baseline, after the 12-week intervention, and at 3 and 6 months post intervention. We will conduct economic analyses and mixed-method process evaluations (Phase IIA).

ETHICS AND DISSEMINATION

The Health and Disability Ethics Committee approved the study protocol (HDEC18/CEN/162). Phase III involves dissemination of findings guided by the PAR team as outcomes become apparent.

Associations between biased threat interpretations, fear and avoidance of pain and pain-linked disability in adolescent chronic pain patients

BACKGROUND

Biased interpretations of ambiguous bodily threat situations characterize youth with chronic pain, and have been associated with functional disability for this population. Despite predictions by the fear-avoidance model of chronic pain, that fear and avoidance of pain explain the association between threat perceptions and disability, this has not yet been explored in youth with chronic pain. This study aimed to address this gap by investigating these proposed relationships, in addition to the association between bodily threat interpretations and daily aspects of disability (as well as social, and emotional impairments).

METHOD

Sixty-eight adolescents aged 11-18 years old with a clinical diagnosis of chronic pain completed an extended version of the Adolescent Interpretations of Bodily Threat task to assess interpretations of bodily and social threat situations, alongside measures of disability and fear and avoidance of pain.

RESULTS

Using mediation analysis, fear and avoidance of pain statistically accounted for the relationship between negative bodily threat interpretations and functional disability. Significant associations were also demonstrated between negative bodily threat interpretations and adolescent-reported impairments in daily, emotional and social impairments. Data revealed a significant relationship between negative social interpretations and daily functional disability.

CONCLUSIONS

Findings indicate the clinical relevance of bodily and social threat interpretations, and fear and avoidance of pain, for this population and raise further questions regarding the content-specificity of threat interpretations.

SIGNIFICANCE

Psychological theories of pain-associated impact and disability point to fear and avoidance of pain, as well as information-processing biases. Here, we present novel data showing the clinical relevance of bodily and social threat interpretations in explaining pain-related disability amongst youth with chronic pain, potentially by shaping fear and avoidance of pain. Longitudinal designs will be required to assess these temporally sensitive mediation pathways.

Nonsteroidal Anti-inflammatory Drugs vs Cognitive Behavioral Therapy for Arthritis Pain: A Randomized Withdrawal Trial

IMPORTANCE

Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed for knee osteoarthritis. However, they are associated with uncertain long-term clinical benefit and significant toxic effects.

OBJECTIVE

To evaluate whether discontinuing NSAIDs and engaging in a telephone-based cognitive behavioral therapy (CBT) program is noninferior to continuing NSAIDs for patients with knee osteoarthritis.

DESIGN, SETTING, AND PARTICIPANTS

The Stopping NSAIDs for Arthritis Pain multicenter randomized withdrawal trial was conducted for 364 patients taking NSAIDs for knee osteoarthritis pain on most days of the week for at least 3 months between September 1, 2013, and September 30, 2018. Analysis was performed on an intent-to-treat basis.

INTERVENTIONS

Participants discontinued their current NSAID and took 15 mg per day of meloxicam daily during a 2-week run-in period. Those who remained eligible were randomized in a 1:1 ratio to receive meloxicam or placebo for 4 weeks (blinded phase 1). Participants receiving meloxicam then continued this medication for 10 weeks, while those receiving placebo participated in a 10-week CBT program (unblinded phase 2).

MAIN OUTCOMES AND MEASURES

The primary outcome measure was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score at 4 weeks with the noninferiority margin set at 1. Secondary outcomes included the area under the curve of the pain score after 4 weeks as well as the WOMAC pain score, area under the curve of the pain score, WOMAC disability score, and global impression of change after treatment at 14 weeks.

RESULTS

A total of 180 participants (161 men; mean [SD] age, 58. 2 [11.8] years) were randomized to receive placebo followed by CBT, and a total of 184 participants (154 men; mean [SD] age, 58.5 [10.0] years) were randomized to receive meloxicam. After adjustment for baseline pain and study site, the estimated mean difference in WOMAC pain score between the placebo and meloxicam groups after 4 weeks was 1.4 (95% CI, 0.8-2.0; noninferiority test P = .92). At week 14, the adjusted mean difference in WOMAC pain score between the placebo (followed by CBT) and meloxicam groups was 0.8 (95% CI, 0.2-1.4; noninferiority P = .28). There was no statistically significant difference in the global impression of change (mean difference in scores, -0.2; 95% CI, -0.4 to 0.1; P = .15) or lower extremity disability (mean difference in scores, 0.9; 95% CI, -1.4 to 3.2; P = .45) between the 2 groups after 14 weeks.

CONCLUSIONS AND RELEVANCE

Among patients with knee osteoarthritis, placebo and CBT (after placebo) are inferior to meloxicam. However, the WOMAC pain score differences between the 2 groups were small, and there were no statistically significant differences in participants' global impression of change or function after 14 weeks.

Illness perceptions of youths with functional disorders and their parents: An interpretative phenomenological analysis study

BACKGROUND

Functional disorders, defined as disorders with no clear medical explanation, are common and impose a significant burden on youths, their families, healthcare services and society as a whole. Currently, the literature describes resistance among patients and their families towards psychological symptom explanations and treatments. More knowledge about the thoughts and understandings of youths with functional disorders and their parents is needed. The aim of this study was to explore the illness perceptions of youths with severe functional disorders and their parents.

METHODS

A qualitative interview study using interpretative phenomenological analyses. The study included 11 youths aged 11-15 years with functional disorders and their parents, where interviews were performed at the point of referral from a somatic to a psychiatric treatment setting.

RESULTS

Analyses identified three main themes. Themes 1(Ascribing identity to the disorder) and 2 (Monocausal explanations) explore key elements of the participants' illness perceptions, and theme 3 (Mutable illness perceptions) explores how illness perceptions are influenced by experiences from healthcare encounters.

CONCLUSIONS

The label 'functional disorder' was poorly integrated in the illness perceptions of the youths and their parents. Participants used a monocausal and typically physical explanation rather than a multicausal biopsychosocial explanation for their symptoms.

Technology use and preferences to support clinical practice guideline awareness and adherence in individuals with sickle cell disease

Objective

Sickle cell disease (SCD) is a chronic condition affecting over 100 000 individuals in the United States, predominantly from vulnerable populations. Clinical practice guidelines, written for providers, have low adherence. This study explored knowledge about guidelines; desire for guidelines; and how technology could support guideline awareness and adherence, examining current technology uses, and user preferences to inform design of a patient-centered guidelines application in a chronic disease.

Methods

This cross-sectional mixed-methods study involved semi-structured interviews, surveys, and focus groups of adolescents and adults with SCD. We evaluated interest, preferences, and anticipated benefits or barriers of a patient-centered adaptation of SCD practice guidelines; prospective technology uses for health; and barriers to technology utilization.

Results

Forty-seven individuals completed surveys and interviews, and 39 participated in three separate focus groups. Most participants (91%) were unaware of SCD guidelines, but almost all (96%) expressed interest in a guidelines application, identifying benefits (knowledge, activation, individualization, and rewards), and barriers (poor information, low motivation, and resource limitations). Current technology health uses included information access, care coordination, and reminders about health-related actions. Prospective technology uses included informational messaging and timely alerts. Barriers to technology use included lack of interest, lack of utility, and preference for direct communication.

Conclusions

This study's findings can inform the design of clinical practice guideline applications, suggesting a promising role for technology to engage patients, facilitate care decisions and actions, and improve outcomes.

Moderators of Internet-Delivered Cognitive-Behavioral Therapy for Adolescents With Chronic Pain: Who Benefits From Treatment at Long-Term Follow-Up?

Cognitive behavioral therapy (CBT) is effective for pediatric chronic pain, but little is understood about which youth are most likely to benefit. The current study aimed to identify individual characteristics for which CBT yielded the greatest (and least) clinical benefit among adolescents with chronic pain participating in a multicenter randomized controlled trial of Internet-delivered CBT (WebMAP2). A total of 273 adolescents ages 11 to 17 with chronic pain (M age = 14.7; 75.1% female) were randomly assigned to Internet-delivered CBT or Internet-delivered pain education and evaluated at pretreatment, post-treatment, and 2 longer term follow-up periods (6 and 12 months). Multilevel growth models tested several adolescent- and parent-level moderators of change in pain-related disability including 1) adolescent age, sex, pain characteristics, distress, and sleep quality and 2) parent education level, distress, and protective parenting behavior. Younger adolescents (ages 11-14; vs older adolescents ages 15-17) and those whose parents experienced lower levels (vs higher levels) of emotional distress responded better to Internet CBT treatment, showing greater improvements in disability up to 12 months post-treatment. This study expands knowledge on who benefits most from Internet-delivered psychological treatment for youth with chronic pain in the context of a large multicenter randomized controlled trial, suggesting several avenues for maximizing treatment efficacy and durability in this population. PERSPECTIVE: This study identified adolescent- and parent-level predictors of treatment response to Internet-based CBT for pediatric chronic pain up to 12 months later. Younger adolescents and those whose parents had lower levels of distress may particularly benefit from this intervention. Older adolescents and those whose parents exhibit higher distress may require alternative treatment approaches.

Pain among children and adults living with arthrogryposis multiplex congenita: A scoping review

Clinical interventions and research have mostly focused on the orthopedic and genetic outcomes of individuals with arthrogryposis multiplex congenita (AMC), and although pain has gained recognition as an important issue experienced by individuals with AMC, it has received little attention within the AMC literature. The aims of this scoping review were to describe the pain experiences of children and adults with AMC, to identify pain assessment tools and management techniques, and document the impact of pain on participation in everyday activities among children and adults with AMC. A search of the literature was conducted in four search engines and identified a total of 89 articles. Once study eligibility was reviewed, 21 studies met the selection criteria and were included in this review. Pain appears to be more commonly experienced in adults with AMC compared with children with AMC, with individuals having undergone multiple corrective procedures self-reporting pain more often. In adult populations, musculoskeletal chronic pain is a significant problem, resulting in restrictions in activities of daily living, mobility, and participation. Researchers and clinicians must agree on the use of validated measures appropriate for evaluating pain in AMC and the use of appropriate pain management techniques to relieve pain. Pediatric studies should focus on determining how commonly pain is experienced in infants, children, and adolescents with AMC. Pain in adults with AMC should be acknowledged to offer proper client-centered interventions throughout the lifespan.

Cognitive-behavioural treatment of functional neurological symptoms (conversion disorder) in children and adolescents: A case series

AIM

To describe a cognitive-behavioural treatment and clinical outcomes in a series of children with functional neurological symptoms (FNS).

METHOD

Thirty-six children with FNS were assessed and of these twenty-two (13 male, 9 female) with a mean age 14.5 years (SD = 2.6, range 6-17 years) completed treatment with cognitive behaviour therapy embedded in routine child and adolescent clinical/systemic practice. Treatment outcomes were measured at baseline and post-intervention on the Child Global Assessment Scale (CGAS), Strengths and Difficulties Questionnaire (SDQ), Goal Based Outcomes (GBO) and Revised Child Anxiety and Depression Scale (RCADS).

RESULTS

Scores on the CGAS improved significantly post-intervention (p < 0.001) with 82% of participants showing reliable change. Individualised goals (GBO) also showed clinically meaningful gains. Standard measures of emotional and behavioural symptoms (SDQ and RCADS) did not correlate well with clinical diagnoses, were usually subthreshold at baseline, and did not show significant improvement post-intervention.

INTERPRETATION

The outcome of this pilot study suggests that CBT can be effective in the rehabilitation of young patients with FNS. Detection of common comorbid psychiatric disorders was not assisted by use of standardised measures, although most participants were clinically anxious or depressed. More research is needed to understand why children with FNS and their parents may not endorse mental health symptoms on questionnaires, and to further evaluate interventions within randomised controlled trials.

Update and future perspective of behavioral medicine in the treatment for chronic pain

Chronic pain is a biopsychosocial condition, and behavioral medicine has made significant contributions to the understanding of the phenomenon and optimization of therapeutic outcomes. The objective of this article is to provide future perspectives of behavioral medicine in pain management based upon recent development in the field. We will briefly review the mainstream approach of cognitive-behavioral therapy, its variations and new and innovative approaches that are on the horizon. We also review strategies that address potential barriers to pain management. Behavioral medicine is a promising field in pain medicine. The future growth is likely to come from addressing how we incorporate the patient heterogeneity into our treatment approaches and a better understanding of its role in a multimodal treatment.

Neurobiological mechanisms underlying the sleep-pain relationship in adolescence: A review

Adolescence characterizes a period of significant change in brain structure and function, causing the neural circuitry to be particularly susceptible to the environment and various other experiences. Chronic pain and sleep deprivation represent major health issues that plague adolescence. A bidirectional relationship exists between sleep and pain; however, emerging evidence suggests that sleep disturbances have a stronger influence on subsequent pain than vice versa. The neurobiological underpinnings of this relationship, particularly during adolescence, are poorly understood. This review examines the current literature regarding sleep and pain in adolescence, with a particular focus on the neurobiological mechanisms underlying pain, sleep problems, and the neural circuitry that potentially links the two. Finally, a research agenda is outlined to stimulate future research on this topic. Given the high prevalence of these health issues during adolescence and the debilitating effects they inflict on nearly every domain of development, it is crucial that we determine the neurobiological mechanisms fundamental to this relationship and identify potential therapeutic strategies.

Internet-Delivered Exposure-Based Cognitive-Behavioral Therapy for Adolescents With Functional Abdominal Pain or Functional Dyspepsia: A Feasibility Study

Functional abdominal pain (FAP) and functional dyspepsia (FD) are common in adolescents and associated with low quality of life. Exposure-based cognitive-behavioral therapy (CBT) is efficient for adult and adolescent irritable bowel syndrome (IBS), but has never been evaluated for adolescent FAP/FD. The aim of this study was to evaluate the feasibility and potential efficacy of a novel disorder-specific Internet-delivered CBT (Internet-CBT) for adolescents with FAP or FD, using an uncontrolled open pilot including 31 adolescents. The Internet-CBT consisted of 10 weekly online modules, which focused mainly on exposure to abdominal symptoms. Parents received modules to help them reduce unhelpful parental behaviors. Participants reported the treatment to be credible, and an overall satisfaction with the treatment. Data attrition rate was low (7%) and adherence to treatment was acceptable. We saw a significant and large effect on the primary outcome, pain intensity, at posttreatment (d = 1.20, p < .001) that was further improved after 6 months (d = 1.69, p < .001). Participants also made significant and large improvements on gastrointestinal symptoms (d = 0.84, p < .001) and quality of life (d = 0.84, p < .001) that were sustained or further improved at follow-up 6 months after treatment. This study demonstrated that exposure-based Internet-CBT, tailored for adolescents with FAP or FD, is a feasible treatment that potentially improves pain intensity, gastrointestinal symptoms, and quality of life.

Internet- and mobile-based aftercare and relapse prevention in mental disorders: A systematic review and recommendations for future research

BACKGROUND

Mental disorders are characterized by a high likelihood of recurrence. Thus, aftercare and follow-up interventions aim to maintain treatment gains and to prevent relapse. Internet- and mobile-based interventions (IMIs) may represent promising instruments in tertiary prevention. This systematic review summarizes and evaluates the research on the efficacy of IMIs as aftercare or follow-up interventions for adults with mental health issues.

METHODS

A systematic database search (PsycInfo, MEDLINE, CENTRAL) was conducted and studies selected according to predefined eligibility criteria (RCTs, adult population, clinical symptoms/disorder, assessed with validated instruments, clinical-psychological intervention rationale, aftercare/follow-up intervention, web-/mobile-based, minimum follow-up measurement of three months, inclusion of a control group). Inspected outcomes were symptom severity, recurrence- and rehospitalization rates, functioning, quality of life and adherence to primary treatment.Systematic review registration: PROSPERO CRD42017055289.

RESULTS

Sixteen RCTs met the inclusion criteria, covering trials on depression (n = 5), eating disorders (n = 4) and transdiagnostic interventions (n = 7). The majority of the interventions were based on Cognitive Behavioral Therapy (CBT) principles and were web-based (n = 11). Methodological quality of included studies was suboptimal. Limitations included attrition bias and non-specification of routine care co-interventions. IMIs yielded small to medium post-treatment effects for symptom severity (d = -0.08 - d = -0.45) in comparison to control groups. Best evidence base was found for symptom severity of depression and anxiety. Study results regarding recurrence and rehospitalization were inconsistent.

DISCUSSION

There is some evidence, that IMIs are feasible instruments for maintaining treatment gains for some mental disorders. However, further high quality, large-scale trials are needed to expand research fields, improve adherence to and uptake of IMIs and facilitate implementation of effective interventions into routine care.

Assessment and patient selection process for a pain management programme: a case study in specialty care

Introduction

The present study audited the process of assessing and selecting patients for a pain management programme with the aim of reviewing best practice in the light of the latest British Pain Society guidelines for pain management programmes for adults. The guidelines include defined inclusion/exclusion criteria and it was explored how they are used by clinicians providing a pain management service.

Method

The records of 200 consecutive patients who attended a multidisciplinary assessment for a central London specialist Pain Management Service from September 2014 to December 2014 were audited. The proportions of patients who were offered a programme, were discharged or referred for a different service were calculated. Clinic letters were reviewed to collect information on assessment outcomes, recommendations and inclusion/exclusion criteria used.

Results

About half the patients (53%) seen for assessment were offered treatment within the service, most frequently the intensive residential programme (30.5%, with an additional 11.6% offered case management first), followed by the five session outpatient programme (8.1%) and a minority was offered individual treatment (2.5%); 44.7% of the patients were discharged following the assessment. The three most frequently used reasons for exclusion were: not ready to engage with the pain management approach (35%), complex psychological or other needs needing to be prioritised (29.5%) and the patient declining a programme (19.3%).

Conclusion

Reviewing the use of inclusion/exclusion criteria revealed some challenges regarding patient selection. For example, a sizable proportion of patients were still seeking pain reduction and were not open to a self-management approach when this was the recommended treatment for them. Complex patients might need other treatment approaches before they can be considered for a programme. Having a range of pain management options of varying intensities available seems helpful in meeting individual patient need.

Somatosensory function and pain in extremely preterm young adults from the UK EPICure cohort: sex-dependent differences and impact of neonatal surgery

BACKGROUND

Surgery or multiple procedural interventions in extremely preterm neonates influence neurodevelopmental outcome and may be associated with long-term changes in somatosensory function or pain response.

METHODS

This observational study recruited extremely preterm (EP, <26 weeks' gestation; n=102, 60% female) and term-born controls (TC; n=48) aged 18-20 yr from the UK EPICure cohort. Thirty EP but no TC participants had neonatal surgery. Evaluation included: quantitative sensory testing (thenar eminence, chest wall); clinical pain history; questionnaires (intelligence quotient; pain catastrophising; anxiety); and structural brain imaging.

RESULTS

Reduced thermal threshold sensitivity in EP vs TC participants persisted at age 18-20 yr. Sex-dependent effects varied with stimulus intensity and were enhanced by neonatal surgery, with reduced threshold sensitivity in EP surgery males but increased sensitivity to prolonged noxious cold in EP surgery females (P<0.01). Sex-dependent differences in thermal sensitivity correlated with smaller amygdala volume (P<0.05) but not current intelligence quotient. While generalised decreased sensitivity encompassed mechanical and thermal modalities in EP surgery males, a mixed pattern of sensory loss and sensory gain persisted adjacent to neonatal scars in males and females. More EP participants reported moderate-severe recurrent pain (22/101 vs 4/48; χ2=0.04) and increased pain intensity correlated with higher anxiety and pain catastrophising.

CONCLUSIONS

After preterm birth and neonatal surgery, different patterns of generalised and local scar-related alterations in somatosensory function persist into early adulthood. Sex-dependent changes in generalised sensitivity may reflect central modulation by affective circuits. Early life experience and sex/gender should be considered when evaluating somatosensory function, pain experience, or future chronic pain risk.

The Pain Course: 12- and 24-Month Outcomes From a Randomized Controlled Trial of an Internet-Delivered Pain Management Program Provided With Different Levels of Clinician Support

Little is known about the long-term outcomes of emerging Internet-delivered pain management programs. The current study reports the 12- and 24-month follow-up data from a randomized controlled trial (n = 490) of an Internet-delivered pain management program, the Pain Course. The initial results of the trial to the 3-month follow-up have been reported elsewhere. There were significant improvements in disability, depression, anxiety, and pain levels across 3 treatment groups receiving different levels of clinician support compared with a treatment as the usual control. No marked or significant differences were found between the treatment groups either after treatment or at the 3-month follow-up. The current study obtained long-term follow-up data from 78% and 79% of participants (n = 397) at the 12-month and 24-month follow-up marks, respectively. Clinically significant decreases (average percent reduction; Cohen's d effect sizes) were maintained at the 12- and 24-month follow-ups for disability (average reduction ≥27%; d ≥ .67), depression (average reduction ≥36%; d ≥ .80), anxiety (average reduction ≥38%; d ≥ .66), and average pain levels (average reduction ≥21%; d ≥ .67). No marked or consistent differences were found among the 3 treatment groups. These findings suggest that the outcomes of Internet-delivered programs may be maintained over the long term. PERSPECTIVE: This article presents the long-term outcome data of an established Internet-delivered pain management program for adults with chronic pain. The clinical improvements observed during the program were found to be maintained at the 12- and 24-month follow-up marks. This finding indicates that these programs can have lasting clinical effects.

Evaluation of uptake and effect on patient-reported outcomes of a clinician and patient co-led chronic musculoskeletal pain self-management programme provided by the UK National Health Service

In the United Kingdom, chronic pain affects approximately 28 million adults, creating significant healthcare and socio-economic costs. The aim was to establish whether a programme designed to use best evidence of content and delivery will be used by patients with significant musculoskeletal pain problems. Of 528 patients recruited, 376 participated in a 7-week-long group-based self-management programme (SMP) co-delivered by clinical and lay tutors. Of these, 308 patients (mean age, 53 years; 69% females, 94% White) completed at least five SMP sessions. Six months after pre-course assessment, participants reported significantly improved patient activation and health status, lower depression and anxiety scores, decreased pain severity and interference, and improved self-management skills. There were no improvements in health state and pain self-efficacy. Uptake rate was 71% and completion 82%. The results should be of value to commissioners of pathways of care for the large numbers of patients attending the English NHS for chronic musculoskeletal pain.

Pilot Randomized Trial of Integrated Cognitive-Behavioral Therapy and Neuromuscular Training for Juvenile Fibromyalgia: The FIT Teens Program

Cognitive-behavioral therapy (CBT) improves coping and daily functioning in adolescents with juvenile fibromyalgia (JFM), but is less effective in reducing pain. This pilot trial evaluated the efficacy of a novel intervention (Fibromyalgia Integrative Training for Teens; FIT Teens) which integrates CBT with specialized neuromuscular exercise training to enhance the effect of treatment on reducing pain and disability. Forty adolescents with JFM (12-18 years) were randomized to CBT-only or FIT Teens. Treatment was conducted in group-based sessions over 8 weeks with assessments at baseline, post-treatment, and 3-month follow-up (primary end point). Primary outcomes were pain intensity and functional disability. Secondary outcomes were depressive symptoms, fear of movement, and pain catastrophizing. Thirty-six participants (mean age=15.33 years; 90% female) completed the program. Intent to treat analysis was conducted to evaluate differences between the FIT Teens and CBT groups from baseline to 3-month follow-up, controlling for baseline group differences. Participants in the FIT Teens group showed significantly greater decreases in pain than the CBT group. FIT Teens participants also showed significant improvements in disability, but did not differ from CBT-only at the 3-month end point. Results provide preliminary evidence that the FIT Teens intervention provides added benefits beyond CBT in the treatment of JFM, particularly in pain reduction.

PERSPECTIVE

Results from this pilot randomized controlled trial of a new combined CBT and specialized neuromuscular exercise intervention (FIT Teens), compared with CBT alone suggested that FIT Teens offers stronger treatment benefits than CBT alone at initial treatment follow-up, especially with respect to the outcome of pain reduction.

Integrative Medicine for the Treatment of Persistent Pain

Integrative health modalities can provide useful tools in the management of persistent pain in the primary care setting. These modalities, such as acupuncture, mind-body medicine, diet and herbs, and movement strategies can be safely used and may provide patients with hope and empowerment. It is highly recommended that the patient work alongside trained professionals for a given modality and/or an interprofessional team.

The role of avoidance behavior in the treatment of adolescents with irritable bowel syndrome: A mediation analysis

Irritable bowel syndrome (IBS) is common in adolescents with a pronounced negative impact on quality of life. A pattern of avoidance behavior is commonly seen in the IBS population, which is associated with more gastrointestinal (GI) symptoms. Exposure-based cognitive behavior therapy (CBT) targets the avoidance behavior to reduce symptoms, but it is unknown whether reduced avoidance is a mediator of symptom improvement in adolescent IBS. Stress has been suggested to play a key role in worsening GI symptoms and is also a potential mediator of the treatment effect in IBS. This study was based on data from a randomized controlled trial (N = 101) that evaluated exposure-based internet-delivered CBT (Internet-CBT) compared with a wait-list for adolescents with IBS. We investigated whether avoidance behavior and perceived stress mediated the improvement in global GI symptoms due to treatment. We found that a change in avoidance behavior, but not perceived stress, mediated the effect of exposure-based Internet-CBT on GI symptoms. The decrease in avoidance behavior explained a large portion (67%) of the total treatment effect. Moreover, a unidirectional relationship over time was observed between avoidance behavior and GI symptoms. Our conclusion is that exposure-based CBT in adolescent IBS reduces avoidance and, consequently, reduces GI symptoms.

Effect on Health Care Costs for Adolescents Receiving Adjunctive Internet-Delivered Cognitive-Behavioral Therapy: Results of a Randomized Controlled Trial

The economic burden of pediatric chronic pain is high, with an estimated annual cost of $19.5 billion. Little is known about whether psychological treatment for pediatric chronic pain can alter health care utilization for youth. The primary aim of this secondary data analysis was to evaluate the effect of adjunctive internet cognitive-behavioral therapy intervention or adjunctive internet education on health care-related economic costs in a cohort of adolescents with chronic pain recruited from interdisciplinary pain clinics across the United States. For the full sample, health care expenditures significantly decreased from the year before the intervention to the year after the intervention. Results indicated that the rate of change in health care costs over time was not significantly different between the internet cognitive-behavioral therapy intervention and adjunctive internet education groups. Further research is needed to replicate these findings and determine patterns and drivers of health care costs for youth with chronic pain evaluated in interdisciplinary pain clinics and whether psychological treatments can alter these patterns. This trial was registered at clinicaltrials.gov (identifier NCT01316471).

PERSPECTIVE

Health care expenditures significantly decreased in youth with chronic pain from the year before initiating treatment to the following year in both intervention conditions, adjunctive internet cognitive-behavioral therapy and adjunctive internet education. Contrary to our hypothesis, the rate of change in health care costs over time was not significantly different between intervention conditions.

Randomized Controlled Trial of Online Acceptance and Commitment Therapy for Fibromyalgia

In this study, 67 participants (95% female) with fibromyalgia (FM) were randomly assigned to an online acceptance and commitment therapy (online ACT) and treatment as usual (TAU; ACT + TAU) protocol or a TAU control condition. Online ACT + TAU participants were asked to complete 7 modules over an 8-week period. Assessments were completed at pre-treatment, post-treatment, and 3-month follow-up periods and included measures of FM impact (primary outcome), depression, pain, sleep, 6-minute walk, sit to stand, pain acceptance (primary process variable), mindfulness, cognitive fusion, valued living, kinesiophobia, and pain catastrophizing. The results indicated that online ACT + TAU participants significantly improved in FM impact, relative to TAU (P <.001), with large between condition effect sizes at post-treatment (1.26) and follow-up (1.59). Increases in pain acceptance significantly mediated these improvements (P = .005). Significant improvements in favor of online ACT + TAU were also found on measures of depression (P = .02), pain (P = .01), and kinesiophobia (P = .001). Although preliminary, this study highlights the potential for online ACT to be an efficacious, accessible, and cost-effective treatment for people with FM and other chronic pain conditions.

PERSPECTIVE

Online ACT reduced FM impact relative to a TAU control condition in this randomized controlled trial. Reductions in FM impact were mediated by improvements in pain acceptance. Online ACT appears to be a promising intervention for FM.
