Headstrong intervention for pediatric migraine headache: a randomized clinical trial

Risk factors for migraine disease progression: a narrative review for a patient-centered approach

BACKGROUND

In individuals with migraine, attacks may increase in frequency, severity, or both. Preventing migraine progression has emerged as a treatment goal in headache subspecialty practice, but there may be less awareness in general neurology or primary care settings where most people with migraine who seek treatment consult. Herein, we review the definition of and risk factors for migraine progression and consider strategies that could reduce its risk.

METHODS

A group of headache expert healthcare professionals, clinicians, and researchers reviewed published evidence documenting factors associated with increased or decreased rates of migraine progression and established expert opinions for disease management recommendations. Strength of evidence was rated as good, moderate, or based solely on expert opinion, using modified criteria for causation developed by AB Hill.

RESULTS

Migraine progression is commonly operationally defined as the transition from ≤ 15 to ≥ 15 monthly headache days among people with migraine; however, this does not necessarily constitute a fundamental change in migraine biology and other definitions should be considered. Established and theoretical key risk factors for migraine progression were categorized into five domains: migraine disease characteristics, treatment-related factors, comorbidities, lifestyle/exogenous factors, and demographic factors. Within these domains, good evidence supports the following risk factors: poorly optimized acute headache treatment, cutaneous allodynia, acute medication overuse, selected psychiatric symptoms, extra-cephalic chronic pain conditions, metabolism-related comorbidities, sleep disturbances, respiratory conditions, former/current high caffeine intake, physical inactivity, financial constraints, tobacco use, and personal triggers as risk factors. Protective actions that may mitigate migraine progression are sparsely investigated in published literature; our discussion of these factors is primarily based on expert opinion.

CONCLUSIONS

Recognizing risk factors for migraine progression will allow healthcare providers to suggest protective actions against migraine progression (Supplementary Fig. 1). Intervention studies are needed to weight the risk factors and test the clinical benefit of hypothesized mitigation strategies that emerge from epidemiological evidence.

Quality of life in children suffering from headaches: a systematic literature review

BACKGROUND

Headaches are the most common complaints among pediatric populations. Determining the cause and appropriate treatment for headaches may be challenging and costly, and the impact of headaches on the lives of patients and their families is not well understood.

OBJECTIVE

A systematic literature review was conducted to examine what PROMs are currently used, and to identify quality of life (QoL) concepts important to children suffering from headaches and any known determinants of QoL.

METHODS

Embase, Medline, Web of Science, CINAHL, EBSCOhost, PsychINFO, Cochrane CENTRAL and Google Scholar were searched from their inception through to June 2021. Studies investigating QoL, using a validated outcome measure in pediatric patients with headaches, were included. Relevant studies were identified through title and abstract screening and full text review by two independent reviewers. A citation review of included studies was performed. QoL concepts were extracted from the outcome measures that were used in each study to develop a preliminary conceptual model of QoL in children suffering from headaches. Determinants of QoL were also identified and categorized.

RESULTS

A total of 5421 studies were identified in the search. Title and abstract screening resulted in the exclusion of 5006 studies. Among the 415 studies included for full text review, 56 were eligible for final analysis. A citation review resulted in the addition of five studies. Most studies were conducted in high-income countries and included a patient-sample accordingly (n = 45 studies). Sixteen different PROMs were identified in the included studies, of which the PedsQL was used the most often (n = 38 studies). The most common health concepts reported were physical functioning (n = 113 items), social and psychological wellbeing (N = 117, n = 91 resp.). Twenty-five unique determinants of QoL were extracted from the included studies.

CONCLUSION

There is a need for a condition-specific PROM to facilitate the measurement of QoL outcomes in the pediatric headache population. A conceptual model was developed based on the findings from the health concepts. Findings from this review could be used for future qualitative interviews with pediatric patients with headaches to elicit and refine important QoL concepts.

Evidence Mapping Based on Systematic Reviews of Cognitive Behavioral Therapy for Neuropathic Pain

Objective

This evidence mapping is aimed at identifying, summarizing, and analyzing the available evidence on cognitive behavioral therapy (CBT) for neuropathic pain (NP).

Methods

This study was conducted following the methodology of Global Evidence Mapping (GEM). Searches were conducted in PubMed, Embase, the Cochrane Library, and PsycINFO to identify systematic reviews (SRs) with or without meta-analysis published before February 15, 2022. The authors independently assessed eligibility, extracted data, and evaluated the methodological quality of the included SRs using AMSTAR-2. The results were presented in the tables and a bubble plot based on the identified population-intervention-comparison-outcome (PICO) questions.

Results

A total of 34 SRs met the eligibility criteria. According to the AMSTAR-2, 2 SRs were rated "high," 2 SRs were rated "moderate," 6 SRs were rated "low," and 24 SRs were rated "critically low." The most common study design utilized to evaluate the efficacy of CBT for NP was the randomized controlled trial. In total, 24 PICOs were identified. Migraine was the most studied population. CBT for NP usually reaches the "potentially better" result at follow-up.

Conclusions

Evidence mapping is a useful way to present existing evidence. Currently, the existing evidence on CBT for NP is limited. Overall, the methodological quality of the included SRs was low. Further improvements in the methodological quality of SRs and more research on the most efficient CBT formats for NP are recommended in the future.

Digital headache self-management interventions for patients with a primary headache disorder: A systematic review of randomized controlled trials

OBJECTIVE

This article systematically reviews the empirical literature examining the efficacy of digital headache management interventions for patients with a primary headache disorder.

BACKGROUND

Digital headache management interventions provide opportunities to improve access to behavioral headache interventions to underserved groups.

METHODS

A systematic search of PubMed, Scopus, and EBSCO (PsycInfo, Education Research Complete, ERIC, Health Source: Nursing/Academic Edition, Psychology and Behavioral Sciences Collection) and reference review was conducted. Included studies had to recruit a sample with a primary headache diagnosis, be a randomized controlled trial including a digital component, assess a headache outcome (i.e., frequency, duration, severity, intensity, disability) or quality of life, and be published in English. Two authors independently extracted data for included studies. The methodological quality of studies was assessed using the revised Cochrane risk-of-bias tool.

RESULTS

Thirteen studies with unique interventions met inclusion criteria. More than half of the studies were pilots; however, nearly 70% (9/13) demonstrated significant between-group or within-group improvements on one or more headache-related outcomes. All interventions included some form of relaxation training and the majority were delivered via interactive website. While fewer than half the studies report participant race and/or ethnicity, of those that do, 83% (5/6) reported a predominately White/Caucasian sample.

CONCLUSIONS

Efficacy testing of digital headache interventions is in its infancy with the majority of these studies relying on pilot studies with small samples comprised of homogenous patient populations. Interactive websites were the most common digital medium to deliver digital headache management interventions and have demonstrated promising results. Further testing using large-scale randomized controlled trials and exploration of other digital tools is warranted. Future studies with more diverse samples are needed to inform health equity of digital headache interventions.

Functional improvement in children and adolescents with primary headache after an interdisciplinary multimodal therapy program: the DreKiP study

BACKGROUND

More than 2/3 of children and adolescents in Germany regularly suffer from headaches. Headache-related limitations in everyday life, school drop-out and educational impairment are common. Structured therapy programs for young headache patients are widely missing.

METHODS

One hundred eleven patients with frequent migraine and/or tension type headache were treated in a 15 hour group program in afternoons, parallel with school, parents received 7 hours of therapy. At the beginning of the program (T0), 6 (T1) and 12 months (T2) after completion, data on headache related disability (PedMidas), headache frequency, intensity, and pediatric pain disability score (PPDI) were prospectively collected to investigate the effects of the therapy.

RESULTS

Seventy-five patients (9-19 years, median = 14; 66.7% female) and their parents provided patient reported outcome measures showing at T1 (65 patients) and T2 (47 patients) reduced headache frequency (last 3 months headache days median T0: 30 days; T1: 18 days, reduction of median 12 days since T0; T2: 13 days, reduction of median 17 days since T0). Linear mixed models revealed significant reduction (T0/T1 p = 0,002; T0/T2 p = 0,001). Reduced headache disability has been reported at T1 and T2 (PedMidas median T0 = 30, T1 = 15, T2 = 7; p < 0,001, p < 0,001 respectively). Follow up data of a subgroup of patients 24 months after the treatment point to sustainable effects.

CONCLUSIONS

The interdisciplinary multimodal headache therapy program DreKiP reduces headache frequency and headache related disability significantly 6-12 months following its completion.

Cognitive Behavioral Therapy for Migraine Headache: A Systematic Review and Meta-Analysis

Background and Objectives: Migraine headaches are chronic neurological diseases that reduce the quality of life by causing severe headaches and autonomic nervous system dysfunction, such as facial flushing, nasal stuffiness, and sweating. Their major treatment methods include medication and cognitive behavioral therapy (CBT). CBT has been used for pain treatment and various psychogenic neurological diseases by reducing pain, disability, and emotional disorders caused by symptoms of mental illness and improving the understanding of mental health. This study aimed to evaluate the effectiveness and safety of CBT in treating migraines. Materials and Methods: Seven electronic databases were searched from the date of inception to December 2020. Randomized controlled studies (RCTs) using CBT as an intervention for migraine were included. The primary outcome of this study was to determine the frequency of migraines and the intensity of migraines on Visual Analog Scale (VAS), the frequency of drug use, Migraine Disability Assessment (MIDAS), and Headache Impact Test (HIT-6) index. The two authors independently conducted the data extraction and quality assessment of the included RCTs, and conducted meta-analysis with RevMan V.5.4. Results: Among the 373 studies, 11 RCTs were included in this systematic review. Seven out of the 11 RCTs were conducted in the USA, and four were conducted in the UK, Germany, Iran, and Italy, respectively. Headache frequency and MIDAS scores were statistically significant reduced. In the subgroup analysis, headache strength was significantly reduced. Two of the included studies reported adverse effects, including worsening of migraine intensity and frequency, respiratory symptoms, and vivid memory of a traumatic event. Conclusions: CBT for migraine effectively reduced headache frequency and MIDAS score in meta-analysis and headache intensity subgroup analysis, with few adverse events. Additional RCTs with CBT for migraine headaches are needed for a more accurate analysis.

Telemedicine in Pediatric Headache: A Review and Practical Implementation

Purpose of Review

The purpose of this review was to summarize the current literature about telemedicine in pediatric headache and to provide practical guidance for its implementation.

Recent Findings

There are few studies dedicated to telemedicine in pediatric headache, and existing studies are small. Patients and families report high levels of satisfaction with telemedicine, and most are willing to continue telemedicine visits in the future. Telemedicine demonstrated similar reductions in headache frequency, severity, and duration as patients treated in-person. Remotely delivered psychologic interventions have some utility in reducing headache severity acutely. Families feel telemedicine reduces geographic and financial barriers to care.

Summary

Telemedicine in pediatric headache is a growing field. While there is limited research available, it appears safe, efficacious, and feasible. Headache-related outcomes, including frequency, severity, and duration, were similar amongst telemedicine and in-person visits. Future studies should include larger sample sizes and detailed analysis of adverse outcomes.

Nonpharmacological Interventions for Pediatric Migraine: A Network Meta-analysis

CONTEXT

Migraine is a common neurologic disorder in children and adolescents. However, a comparison of multiple nonpharmacological treatments is lacking.

OBJECTIVE

To examine whether nonpharmacological treatments are more effective than waiting list and whether there are differences between interventions regarding efficacy.

DATA SOURCES

Systematic review and network meta-analysis of studies in Medline, Cochrane, Embase, and PsycINFO published through August 5, 2019.

STUDY SELECTION

Randomized controlled trials of nonpharmacological treatments in children and adolescents diagnosed with episodic migraine.

DATA EXTRACTION

Effect sizes, calculated as standardized mean differences (SMDs) for the primary outcome efficacy, were assessed in a random-effects model.

RESULTS

Twelve studies (N = 576) were included. When interventions were classified into groups on the basis of similarity of treatment components, self-administered treatments, biofeedback, relaxation, psychological treatments, and psychological placebos were significantly more effective than waiting list with effect sizes ranging between SMD = 1.14 (95% confidence interval, 0.09 to 2.19) for long-term psychological placebos to SMD = 1.44 (95% confidence interval, 0.26 to 2.62) for short-term self-administered treatments. However, when all interventions were examined individually (ie, 1 node per intervention), none were significantly more effective compared with waiting list, mainly because of lack of statistical power.

LIMITATIONS

Because of our focus on pediatric migraine, only a small number of studies could be included.

CONCLUSIONS

Our findings reveal that components of nonpharmacological interventions are effective in treating pediatric migraine. Some effects have to be interpreted carefully because they are based on small studies. Future researchers should identify factors associated with individual responses in large, multicentered studies.

Digital Therapeutic Self-Management Intervention in Adolescents With Migraine: Feasibility and Preliminary Efficacy of "Migraine Manager"

OBJECTIVE

The objective of this study was to design, code, and pilot test the feasibility and preliminary efficacy of a self-management digital therapeutic tool for adolescents with migraine.

BACKGROUND

Self-management of migraine in adolescents is complex and has important implications for health outcomes. A comprehensive and accessible approach to self-management is needed for youth with migraine, their parents, and clinicians.

METHODS

An iterative co-design process was used to develop and optimize the Migraine Manager's digital therapeutic self-management tool. Subsequently, 40 adolescents, age 11-18 years, were enrolled in an 8-week single-arm open label trial (N = 36 analyzed). The primary outcome was headache days.

RESULTS

Usage data for Migraine Manager were similar to other health app usage data and feedback from participants was uniformly positive, indicating acceptable feasibility. Preliminary efficacy was demonstrated by a reduction in headache days from 17.2 ± 8.5 at baseline to 7.9 ± 7.2 at 8 weeks (95% CI, -13.0 to -7.8; P < .001). There was also statistically significant improvement in patient physical functioning quality of life reported by both patients (baseline = 55.7 ± 20.4; 8 weeks = 69.7 ± 21.9, P = .005) and parents (baseline = 58.5 ± 22.8; 8 weeks = 74.3 ± 18.1, P = .002), and in parent-reported ingestion issues subscale of the adherence barriers scale from baseline to 8 weeks (baseline = 6.0 ± 2.6; 8 weeks = 5.2 ± 3.0, P = .020).

CONCLUSIONS

A self-management digital therapeutic tool for adolescents with migraine can offer care to patients who might not otherwise receive such services. Migraine Manager demonstrated the feasibility and preliminary efficacy in this pilot trial, highlighting the potential beneficial impact of this tool. Larger controlled trials with long-term follow-up are needed to definitively determine the clinical efficacy of Migraine Manager.

Nonpharmacological Interventions Addressing Pain, Sleep, and Quality of Life in Children and Adolescents with Primary Headache: A Systematic Review

Purpose

Children and adolescents with primary headache are at risk of persistent somatic symptoms and reduced quality of life (Qol) due to pain and pain-related behaviors, such as avoiding school and activities. Sleep is essential to health, and children and adolescents with primary headaches have more sleep complaints than do healthy controls. A treatment approach that addresses multifactorial causes is likely important. Nonpharmacological interventions seem promising. However, knowledge about effective strategies is limited. The objective of this review is to assess the effect of nonpharmacological interventions in randomized controlled trials (RCTs) among children and adolescents with primary headache in order to identify useful strategies.

Patients and methods

Outcome measures are pain, sleep, Qol, and coping versus no intervention or control intervention. Medline, CINAHL, EMBASE, and PsycINFO were searched for eligible trials. ClinicalTrials.gov. was searched for ongoing trials. Initial searches yielded 2588 publications. After initial screening and subsequent full-text review and quality assessment, 13 RCTs reported in 15 articles were selected for review. All reviewers independently assessed study quality using the CONSORT criteria for nonpharmacological interventions.

Results

Cognitive behavioral therapy (CBT), including education on pain-related topics, sleep, coping, and stress management, is an effective strategy for reducing headache and pain within groups over time. Fifteen studies assessed pain, 3 studies assessed sleep, 6 studies assessed Qol, and 11 studies assessed coping.

Conclusion

Strategies identified as useful were parts of CBT interventions. However, it was not possible to identify a single effective intervention addressing pain, sleep, Qol, and coping in children and adolescents with headache, primarily because sleep was infrequently addressed. Various aspects of Qol and coping strategies were assessed, rendering comparison difficult. Strategies for future interventions should include descriptions of theory-driven CBT interventions, depending on clinical setting and based on local resources, to promote a solid evidence base for nonpharmacological interventions.

Psychological therapies (remotely delivered) for the management of chronic and recurrent pain in children and adolescents

BACKGROUND

This is the first update of a review published in 2015, Issue 1. Chronic pain is common during childhood and adolescence and is associated with negative outcomes, such as increased severity of pain, reduced function, and low mood. Psychological therapies, traditionally delivered face-to-face with a therapist, are efficacious at reducing pain intensity and disability. To address barriers to treatment access, such as distance and cost of treatment, technology is being used to deliver these psychological therapies remotely. Therapies delivered remotely, such as via the Internet, computer-based programmes, and smartphone applications, can be used to deliver treatment to children and adolescents with chronic pain.

OBJECTIVES

To determine the efficacy of psychological therapies delivered remotely compared to waiting list, treatment as usual, or active control treatments, for the management of chronic pain in children and adolescents.

SEARCH METHODS

We searched four databases (CENTRAL, MEDLINE, Embase, and PsycINFO) from inception to May 2018 for randomised controlled trials (RCTs) of remotely-delivered psychological interventions for children and adolescents with chronic pain. We searched for chronic pain conditions including, but not exclusive to, headache, recurrent abdominal pain, musculoskeletal pain, and neuropathic pain. We also searched online trial registries, reference sections, and citations of included studies for potential trials.

SELECTION CRITERIA

We included RCTs that investigated the efficacy of a psychological therapy delivered remotely via technology in comparison to an active, treatment as usual, or waiting-list control. We considered blended treatments, which used a combination of technology and up to 30% face-to-face interaction. Interventions had to be delivered primarily via technology to be included, and we excluded interventions delivered via telephone. We included studies that delivered interventions to children and adolescents (up to 18 years of age) with a chronic pain condition or where chronic pain was a primary symptom of their condition (e.g. juvenile arthritis). We included studies that reported 10 or more participants in each comparator arm, at each extraction point.

DATA COLLECTION AND ANALYSIS

We combined all psychological therapies in the analyses. We split pain conditions into headache and mixed (non-headache) pain and analysed them separately. We extracted pain severity/intensity, disability, depression, anxiety, and adverse events as primary outcomes, and satisfaction with treatment as a secondary outcome. We considered outcomes at two time points: first immediately following the end of treatment (known as 'post-treatment'), and second, any follow-up time point post-treatment between three and 12 months (known as 'follow-up'). We assessed risk of bias and all outcomes for quality using the GRADE assessment.

MAIN RESULTS

We found 10 studies with 697 participants (an additional 4 studies with 326 participants since the previous review) that delivered treatment remotely; four studies investigated children with headache conditions, one study was with children with juvenile idiopathic arthritis, one included children with sickle cell disease, one included children with irritable bowel syndrome, and three studies included children with different chronic pain conditions (i.e. headache, recurrent abdominal pain, musculoskeletal pain). The average age of children receiving treatment was 13.17 years.We judged selection, detection, and reporting biases to be mostly low risk. However, we judged performance and attrition biases to be mostly unclear. Out of the 16 planned analyses, we were able to conduct 13 meta-analyses. We downgraded outcomes for imprecision, indirectness of evidence, inconsistency of results, or because the analysis only included one study.Headache conditionsFor headache pain conditions, we found headache severity was reduced post-treatment (risk ratio (RR) 2.02, 95% confidence interval (CI) 1.35 to 3.01); P < 0.001, number needed to treat to benefit (NNTB) = 5.36, 7 studies, 379 participants; very low-quality evidence). No effect was found at follow-up (very low-quality evidence). There were no effects of psychological therapies delivered remotely for disability post-treatment (standardised mean difference (SMD) -0.16, 95% CI -0.46 to 0.13; P = 0.28, 5 studies, 440 participants) or follow-up (both very low-quality evidence). Similarly, no effect was found for the outcomes of depression (SMD -0.04, 95% CI -0.15 to 0.23, P = 0.69, 4 studies, 422 participants) or anxiety (SMD -0.08, 95% CI -0.28 to 0.12; P = 0.45, 3 studies, 380 participants) at post-treatment, or follow-up (both very low-quality evidence).Mixed chronic pain conditionsWe did not find any beneficial effects of psychological therapies for reducing pain intensity post-treatment for mixed chronic pain conditions (SMD -0.90, 95% CI -1.95 to 0.16; P = 0.10, 5 studies, 501 participants) or at follow-up. There were no beneficial effects of psychological therapies delivered remotely for disability post-treatment (SMD -0.28, 95% CI -0.74 to 0.18; P = 0.24, 3 studies, 363 participants) and a lack of data at follow-up meant no analysis could be run. We found no beneficial effects for the outcomes of depression (SMD 0.04, 95% CI -0.18 to 0.26; P = 0.73, 2 studies, 317 participants) and anxiety (SMD 0.53, 95% CI -0.63 to 1.68; P = 0.37, 2 studies, 370 participants) post-treatment, however, we are cautious of our findings as we could only include two studies in the analyses. We could not conduct analyses at follow-up. We judged the evidence for all outcomes to be very low quality.All conditionsAcross all chronic pain conditions, six studies reported minor adverse events which were not attributed to the psychological therapies. Satisfaction with treatment is described qualitatively and was overall positive. However, we judged both these outcomes as very low quality.

AUTHORS' CONCLUSIONS

There are currently a small number of trials investigating psychological therapies delivered remotely, primarily via the Internet. We are cautious in our interpretations of analyses. We found one beneficial effect of therapies to reduce headache severity post-treatment. For the remaining outcomes there was either no beneficial effect at post-treatment or follow-up, or lack of evidence to determine an effect. Overall, participant satisfaction with treatment was positive. We judged the quality of the evidence to be very low, meaning we are very uncertain about the estimate. Further studies are needed to increase our confidence in this potentially promising field.

Psychological interventions for parents of children and adolescents with chronic illness

BACKGROUND

Psychological therapies for parents of children and adolescents with chronic illness aim to improve parenting behavior and mental health, child functioning (behavior/disability, mental health, and medical symptoms), and family functioning.This is an updated version of the original Cochrane Review (2012) which was first updated in 2015.

OBJECTIVES

To evaluate the efficacy and adverse events of psychological therapies for parents of children and adolescents with a chronic illness.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, PsycINFO, and trials registries for studies published up to July 2018.

SELECTION CRITERIA

Included studies were randomized controlled trials (RCTs) of psychological interventions for parents of children and adolescents with a chronic illness. In this update we included studies with more than 20 participants per arm. In this update, we included interventions that combined psychological and pharmacological treatments. We included comparison groups that received either non-psychological treatment (e.g. psychoeducation), treatment as usual (e.g. standard medical care without added psychological therapy), or wait-list.

DATA COLLECTION AND ANALYSIS

We extracted study characteristics and outcomes post-treatment and at first available follow-up. Primary outcomes were parenting behavior and parent mental health. Secondary outcomes were child behavior/disability, child mental health, child medical symptoms, and family functioning. We pooled data using the standardized mean difference (SMD) and a random-effects model, and evaluated outcomes by medical condition and by therapy type. We assessed risk of bias per Cochrane guidance and quality of evidence using GRADE.

MAIN RESULTS

We added 21 new studies. We removed 23 studies from the previous update that no longer met our inclusion criteria. There are now 44 RCTs, including 4697 participants post-treatment. Studies included children with asthma (4), cancer (7), chronic pain (13), diabetes (15), inflammatory bowel disease (2), skin diseases (1), and traumatic brain injury (3). Therapy types included cognitive-behavioural therapy (CBT; 21), family therapy (4), motivational interviewing (3), multisystemic therapy (4), and problem-solving therapy (PST; 12). We rated risk of bias as low or unclear for most domains, except selective reporting bias, which we rated high for 19 studies due to incomplete outcome reporting. Evidence quality ranged from very low to moderate. We downgraded evidence due to high heterogeneity, imprecision, and publication bias.Evaluation of parent outcomes by medical conditionPsychological therapies may improve parenting behavior (e.g. maladaptive or solicitous behaviors; lower scores are better) in children with cancer post-treatment and follow-up (SMD -0.28, 95% confidence interval (CI) -0.43 to -0.13; participants = 664; studies = 3; SMD -0.21, 95% CI -0.37 to -0.05; participants = 625; studies = 3; I² = 0%, respectively, low-quality evidence), chronic pain post-treatment and follow-up (SMD -0.29, 95% CI -0.47 to -0.10; participants = 755; studies = 6; SMD -0.35, 95% CI -0.50 to -0.20; participants = 678; studies = 5, respectively, moderate-quality evidence), diabetes post-treatment (SMD -1.39, 95% CI -2.41 to -0.38; participants = 338; studies = 5, very low-quality evidence), and traumatic brain injury post-treatment (SMD -0.74, 95% CI -1.25 to -0.22; participants = 254; studies = 3, very low-quality evidence). For the remaining analyses data were insufficient to evaluate the effect of treatment.Psychological therapies may improve parent mental health (e.g. depression, anxiety, lower scores are better) in children with cancer post-treatment and follow-up (SMD -0.21, 95% CI -0.35 to -0.08; participants = 836, studies = 6, high-quality evidence; SMD -0.23, 95% CI -0.39 to -0.08; participants = 667; studies = 4, moderate-quality evidence, respectively), and chronic pain post-treatment and follow-up (SMD -0.24, 95% CI -0.42 to -0.06; participants = 490; studies = 3; SMD -0.20, 95% CI -0.38 to -0.02; participants = 482; studies = 3, respectively, low-quality evidence). Parent mental health did not improve in studies of children with diabetes post-treatment (SMD -0.24, 95% CI -0.90 to 0.42; participants = 211; studies = 3, very low-quality evidence). For the remaining analyses, data were insufficient to evaluate the effect of treatment on parent mental health.Evaluation of parent outcomes by psychological therapy typeCBT may improve parenting behavior post-treatment (SMD -0.45, 95% CI -0.68 to -0.21; participants = 1040; studies = 9, low-quality evidence), and follow-up (SMD -0.26, 95% CI -0.42 to -0.11; participants = 743; studies = 6, moderate-quality evidence). We did not find evidence for a beneficial effect for CBT on parent mental health at post-treatment or follow-up (SMD -0.19, 95% CI -0.41 to 0.03; participants = 811; studies = 8; SMD -0.07, 95% CI -0.34 to 0.20; participants = 592; studies = 5; respectively, very low-quality evidence). PST may improve parenting behavior post-treatment and follow-up (SMD -0.39, 95% CI -0.64 to -0.13; participants = 947; studies = 7, low-quality evidence; SMD -0.54, 95% CI -0.94 to -0.14; participants = 852; studies = 6, very low-quality evidence, respectively), and parent mental health post-treatment and follow-up (SMD -0.30, 95% CI -0.45 to -0.15; participants = 891; studies = 6; SMD -0.21, 95% CI -0.35 to -0.07; participants = 800; studies = 5, respectively, moderate-quality evidence). For the remaining analyses, data were insufficient to evaluate the effect of treatment on parent outcomes.Adverse eventsWe could not evaluate treatment safety because most studies (32) did not report on whether adverse events occurred during the study period. In six studies, the authors reported that no adverse events occurred. The remaining six studies reported adverse events and none were attributed to psychological therapy. We rated the quality of evidence for adverse events as moderate.

AUTHORS' CONCLUSIONS

Psychological therapy may improve parenting behavior among parents of children with cancer, chronic pain, diabetes, and traumatic brain injury. We also found beneficial effects of psychological therapy may also improve parent mental health among parents of children with cancer and chronic pain. CBT and PST may improve parenting behavior. PST may also improve parent mental health. However, the quality of evidence is generally low and there are insufficient data to evaluate most outcomes. Our findings could change as new studies are conducted.

Non-pharmacological Approaches for Headaches in Young Age: An Updated Review

Headache disorders are common in children and adolescents. Most of the studies on non-pharmacological treatments have however been carried out on adults. In this review we provide information on recent studies examining non-pharmacological approaches for managing headache in children and adolescents. Our search of SCOPUS for primary studies conducted between January 2010 and July 2018 uncovered 11 controlled studies, mostly addressing behavioral approaches, in which a total of 613 patients with a diagnosis of primary headache, and average age 10.2–15.7 years (30–89% females) were recruited. Non-pharmacological treatments were shown to produce sizeable effects on the classical primary endpoint, i.e., headache frequency, with reductions from baseline ranging between 34 and 78%. Among commonly reported secondary endpoints, particularly disability, quality of life, depression and anxiety, marked improvements were noted as well. Taken as a whole, our findings suggest that non-pharmacological treatments constitute a valid option for the prevention of primary headaches in young age. Future research with higher-quality studies is needed. Particular attention needs to be given to studies that randomize patients to condition, blind researchers in charge of evaluating treatment outcomes, routinely include headache frequency as the primary endpoint, include adequate-length follow-up, address changes in biomarkers of disease and other possible mediators of outcome, and that employ predictive models to enhance the level of evidence for these approaches.

Psychological therapies for the management of chronic and recurrent pain in children and adolescents

BACKGROUND

This is an update of the original Cochrane review first published in Issue 1, 2003, and previously updated in 2009, 2012 and 2014. Chronic pain, defined as pain that recurs or persists for more than three months, is common in childhood. Chronic pain can affect nearly every aspect of daily life and is associated with disability, anxiety, and depressive symptoms.

OBJECTIVES

The aim of this review was to update the published evidence on the efficacy of psychological treatments for chronic and recurrent pain in children and adolescents.The primary objective of this updated review was to determine any effect of psychological therapy on the clinical outcomes of pain intensity and disability for chronic and recurrent pain in children and adolescents compared with active treatment, waiting-list, or treatment-as-usual care.The secondary objective was to examine the impact of psychological therapies on children's depressive symptoms and anxiety symptoms, and determine adverse events.

Searches were undertaken of CENTRAL, MEDLINE, MEDLINE in Process, Embase, and PsycINFO databases. We searched for further RCTs in the references of all identified studies, meta-analyses, and reviews, and trial registry databases. The most recent search was conducted in May 2018.

SELECTION CRITERIA

RCTs with at least 10 participants in each arm post-treatment comparing psychological therapies with active treatment, treatment-as-usual, or waiting-list control for children or adolescents with recurrent or chronic pain were eligible for inclusion. We excluded trials conducted remotely via the Internet.

DATA COLLECTION AND ANALYSIS

We analysed included studies and we assessed quality of outcomes. We combined all treatments into one class named 'psychological treatments'. We separated the trials by the number of participants that were included in each arm; trials with > 20 participants per arm versus trials with < 20 participants per arm. We split pain conditions into headache and mixed chronic pain conditions. We assessed the impact of both conditions on four outcomes: pain, disability, depression, and anxiety. We extracted data at two time points; post-treatment (immediately or the earliest data available following end of treatment) and at follow-up (between three and 12 months post-treatment).

MAIN RESULTS

We identified 10 new studies (an additional 869 participants) in the updated search. The review thus included a total of 47 studies, with 2884 children and adolescents completing treatment (mean age 12.65 years, SD 2.21 years). Twenty-three studies addressed treatments for headache (including migraine); 10 for abdominal pain; two studies treated participants with either a primary diagnosis of abdominal pain or irritable bowel syndrome, two studies treated adolescents with fibromyalgia, two studies included adolescents with temporomandibular disorders, three were for the treatment of pain associated with sickle cell disease, and two studies treated adolescents with inflammatory bowel disease. Finally, three studies included adolescents with mixed pain conditions. Overall, we judged the included studies to be at unclear or high risk of bias.Children with headache painWe found that psychological therapies reduced pain frequency post-treatment for children and adolescents with headaches (risk ratio (RR) 2.35, 95% confidence interval (CI) 1.67 to 3.30, P < 0.01, number needed to treat for an additional beneficial outcome (NNTB) = 2.86), but these effects were not maintained at follow-up. We did not find a beneficial effect of psychological therapies on reducing disability in young people post-treatment (SMD -0.26, 95% CI -0.56 to 0.03), but we did find a beneficial effect in a small number of studies at follow-up (SMD -0.34, 95% CI -0.54 to -0.15). We found no beneficial effect of psychological interventions on depression or anxiety symptoms.Children with mixed pain conditionsWe found that psychological therapies reduced pain intensity post-treatment for children and adolescents with mixed pain conditions (SMD -0.43, 95% CI -0.67 to -0.19, P < 0.01), but these effects were not maintained at follow-up. We did find beneficial effects of psychological therapies on reducing disability for young people with mixed pain conditions post-treatment (SMD -0.34, 95% CI -0.54 to -0.15) and at follow-up (SMD -0.27, 95% CI -0.49 to -0.06). We found no beneficial effect of psychological interventions on depression symptoms. In contrast, we found a beneficial effect on anxiety at post-treatment in children with mixed pain conditions (SMD -0.16, 95% CI -0.29 to -0.03), but this was not maintained at follow-up.Across all pain conditions, we found that adverse events were reported in seven trials, of which two studies reported adverse events that were study-related.Quality of evidenceWe found the quality of evidence for all outcomes to be low or very low, mostly downgraded for unexplained heterogeneity, limitations in study design, imprecise and sparse data, or suspicion of publication bias. This means our confidence in the effect estimate is limited: the true effect may be substantially different from the estimate of the effect, or we have very little confidence in the effect estimate; or the true effect is likely to be substantially different from the estimate of effect.

AUTHORS' CONCLUSIONS

Psychological treatments delivered predominantly face-to-face might be effective for reducing pain outcomes for children and adolescents with headache or other chronic pain conditions post-treatment. However, there were no effects at follow-up. Psychological therapies were also beneficial for reducing disability in children with mixed chronic pain conditions at post-treatment and follow-up, and for children with headache at follow-up. We found no beneficial effect of therapies for improving depression or anxiety. The conclusions of this update replicate and add to those of a previous version of the review which found that psychological therapies were effective in reducing pain frequency/intensity for children with headache and mixed chronic pain conditions post-treatment.

Stress management for headaches in children and adolescents: A review and practical recommendations for health promotion programs and well-being

Stress is considered to be the most common factor reported to trigger headaches in children and adolescents. Although tension-type headache and migraine are the two most common types of headache in children and adolescents, they are often untreated, ignoring their stressful background. We provide a narrative review of the available evidence for health-care professionals involved in stress-related headache management and health promotion programs. An integrative plan is delivered through lifestyle improvement and biopsychosocial modifying stress response techniques. Healthy dietary choices, sleep hygiene, and regular exercise, although limited, are effective for young sufferers. Biopsychosocial therapies such as relaxation, biofeedback, hypnosis, yoga, cognitive behavioral therapy, and acupuncture focus at stress physiological and behavioral relief. Our purpose is to suggest a stress-related headache management to empower children to make healthy choices in order to improve their lifelong well-being and quality of life. We aim to authorize relationship between nurses and other health-care providers with background knowledge around stress management for pediatric headache populations.

Group Education and Multidisciplinary Management for Chronic Headaches Among Adolescents in a Military Treatment Facility: A Retrospective Chart Review

OBJECTIVE

To assess the effect of group education on the frequency of chronic headaches among adolescents.

BACKGROUND

Chronic headaches are a common problem among adolescents with significant psychosocial morbidity. Brief education on lifestyle interventions to decrease headache frequency has established benefits among adult patients but is less proven among adolescents.

METHODS

This study is a chart review examining our experience with a group education program for 155 adolescents, aged 12-17 years old, enrolled in the U.S. military medical system with at least 3 months of chronic headaches who were referred to a headache evaluation clinic. The primary outcome of our study was self-reported number of days with a headache in the previous 30 days based on patient recall. We used a paired samples t-test to measure the change in headache frequency between the frequency reported at the headache class and follow-up more than 6 months after the class.

RESULTS

Most of the adolescents seen in the program were female (114/155 [73.5%]) and suffered from migraine headaches (108/155 [69.8%]). Severe headache-related disability was reported by 40.6% of subjects (63/155). Subjects reported an average of 19 days with headache during the previous 30 days. Females and patients with higher headache-related disability reported a higher number of days with headache. Participation in the group education was associated with an 11.5 (SD 11.9, P < .001) day decrease in the frequency of headaches during the previous 30 days at follow-up at least 6 months after the class, with largest decline seen in patients with the highest level of migraine-related disability at baseline.

CONCLUSION

Based on our retrospective chart review study, group education on headache evaluation and lifestyle management has potential as an effective, low-cost intervention for treatment of chronic headaches among adolescents.

[DreKiP - an outpatient treatment program for children and adolescents with headache]

Headaches are a frequent health problem among children and adolescents. The ocurrence of headaches and the resulting impairments in the quality of life and activities of daily living are modulated by biopsychosocial interactions, which necessitate a complex treatment program. The Dresden Childrens Headache Program (DreKiP) is a multidisciplinary therapy program consisting of eight modules for children and adolescents: education, stress relief, relaxation techniques, physical fitness, climbing therapy, art therapy and sensory training. In addition, there are six modules containing parallel workshops for parents. This outpatient program lasts 2-3 months and is performed parallel to the daily and school routine. Therapy groups consist of 6-8 patients in each age group. In total patients receive 15 h and the parents 7 h of therapy. Concomitant with the program, headache-associated data, such as headache frequency, medication use and school absence are documented. So far 32 children and adolescents in groups of 11, 14-15, 14-16, 17 and 17-18 years old completed the program. Of the 32 patients 19 presented with migraine and tension type headache, 6/32 with migraine and 7/32 with tension type headache only. The median number of headache days was 15 per month and 4 official school absence days per month. Preliminary results 6 months after the end of the therapy program showed reduced frequency of headaches in three quarters of our patients. The headache frequency was reduced from an initial median of 15 days per month to a median of 8 days per month after the program. The multidisciplinary program DreKiP improves the use of therapeutic means in children and adolescents with primary headaches. Children and adolescents with headache-related impairment in activities of daily life in school and leisure times constitute the target group of this therapy.

An update on behavioral treatments in migraine - current knowledge and future options

INTRODUCTION

Besides pharmacological and interventional treatments a variety of non-medical therapeutic options exist for migraine, which has largely been derived from behavioral therapy. Areas covered: For our update we collected available studies via PubMed searches. This review highlights that already consulting of the patient is able to reduce the frequency of migraine attacks. Relaxation techniques, especially progressive muscle relaxation, and various types of biofeedback are effective, as is the implementation of cognitive behavioral therapy. However, recent reviews also point to some existing inconsistencies and methodological limitations. The advent of modern information technology based approaches (e.g. online therapy, smartphone applications) further advanced the arsenal of behavioral treatment regimes. The combination of behavioral treatment options and the combination with pharmacotherapy lead to additive effects. In modern multidisciplinary treatment approaches, behavioral therapy is an indispensable component. Expert commentary: Behavioral treatment in prophylaxis of migraine is as effective as pharmacological treatment with additional effects when pharmacological and behavioral treatment is applied in combination. Novel treatment approaches using online technology and electronic devices offer interesting options that will spread more in the future.

Adolescents with Mild Traumatic Brain Injury Get SMART: An Analysis of a Novel Web-Based Intervention

BACKGROUND

There have been few trials of interventions to facilitate recovery following mild traumatic brain injury (mTBI) in adolescence. To address this gap, we developed and piloted a novel Web-based intervention, entitled Self-Management Activity Restriction and Relaxation Training (SMART), and examined its impact on symptom burden, functional disability, and executive functioning during the month following mTBI in adolescents.

MATERIALS AND METHODS

Open-label, single arm study. Adolescents with recent mTBI and a parent were recruited from the emergency department and provided access upon discharge to SMART-a Web-based program designed to facilitate recovery via self-management and education about symptoms and sequelae associated with mTBI. Symptom burden, functional disability, and executive functioning were rated by both the adolescent and the parent initially and at assessments at 1-, 2- and 4-weeks postinjury. Mixed models analyses were used to examine trajectories on these outcomes.

RESULTS

Of the 21 adolescent/parent dyads enrolled, 13 engaged in the program and reported significant improvement in symptoms over the 4-week program (adolescent, p = 0.0005; parent, p = 0.004). Adolescents spent a median of 35.5 min (range 1.1-107.6) using the program. Parent ratings of the adolescent's functional disability and executive functioning significantly improved over the 4-week period from baseline (p = 0.009 and p = 0.03, respectively), whereas adolescents themselves did not report significant changes in either outcome. All participants improved and there were no adverse outcomes.

CONCLUSION

The SMART program, a novel Web-based intervention, may serve as a self-management tool for adolescents and their parents to assist with the recovery following a recent mTBI.

Electronic behavioral interventions for headache: a systematic review

BACKGROUND

There is increasing interest in using electronic behavioral interventions as well as mobile technologies such as smartphones for improving the care of chronic disabling diseases such as migraines. However, less is known about the current clinical evidence for the feasibility and effectiveness of such behavioral interventions.

OBJECTIVE

To review the published literature of behavioral interventions for primary headache disorders delivered by electronic means suitable for use outside of the clinician's office.

METHODS

An electronic database search of PubMed, PsycINFO, and Embase was conducted through December 11, 2015. All eligible studies were systematically reviewed to examine the modality in which treatment was delivered (computer, smartphone, watch and other), types of behavioral intervention delivered (cognitive behavioral therapy [CBT], biofeedback, relaxation, other), the headache type being treated, duration of treatment, adherence, and outcomes obtained by the trials to examine the overall feasibility of electronic behavioral interventions for headache.

RESULTS

Our search produced 291 results from which 23 eligible articles were identified. Fourteen studies used the internet via the computer, 2 used Personal Digital Assistants, 2 used CD ROM and 5 used other types of devices. None used smartphones or wearable devices. Four were pilot studies (N ≤ 10) which assessed feasibility. For the behavioral intervention, CBT was used in 11 (48 %) of the studies, relaxation was used in 8 (35 %) of the studies, and biofeedback was used in 5 (22 %) of the studies. The majority of studies (14/23, 61 %) used more than one type of behavioral modality. The duration of therapy ranged from 4-8 weeks for CBT with a mean of 5.9 weeks. The duration of other behavioral interventions ranged from 4 days to 60 months. Outcomes measured varied widely across the individual studies.

CONCLUSIONS

Despite the move toward individualized medicine and mHealth, the current literature shows that most studies using electronic behavioral intervention for the treatment of headache did not use mobile devices. The studies examining mobile devices showed that the behavioral interventions that employed them were acceptable to patients. Data are limited on the dose required, long term efficacy, and issues related to the security and privacy of this health data. This study was registered at the PROSPERO International Prospective Register of Systematic Reviews (CRD42015032284) (Prospero, 2015).

Psychiatric comorbidity in childhood and adolescence headache

Primary headaches among children and adolescents have a substantial impact on quality of life, daily activities, social interaction, and school performance in combination with psychopathological symptoms. The main purpose of the present paper is to summarize clinical and epidemiological evidence for psychiatric comorbidity among children and adolescents with headaches, to describe how evidence in headache research suggest different pathways involved in the development and maintenance of these comorbid conditions, and finally suggest some elements professionals may find helpful to assess the scope of complaints, related functional impairment, and potential precipitating factors in planning of more targeted treatments.

Pilot Randomized Controlled Trial of Internet-Delivered Cognitive-Behavioral Treatment for Pediatric Headache

OBJECTIVE

To evaluate the feasibility and preliminary effectiveness of an Internet-delivered cognitive-behavioral therapy (CBT) intervention for adolescents with chronic headache.

BACKGROUND

Headache is among the most common pain complaints of childhood. Cognitive-behavioral interventions are efficacious for improving pain among youth with headache. However, many youth do not receive psychological treatment for headache due to poor access, which has led to consideration of alternative delivery modalities such as the Internet.

METHODS

We used a parallel arm randomized controlled trial design to evaluate the feasibility and preliminary effectiveness of an Internet-delivered family-based CBT intervention, Web-based management of adolescent pain. Adolescents were eligible for the trial if they were a new patient being evaluated in a specialized headache clinic, between 11 and 17 years of age, and had recurrent headache for 3 months or more as diagnosed by a pediatric neurologist. Eighty-three youths were enrolled in the trial. An online random number generator was used to randomly assign participants to receive Internet CBT adjunctive to specialized headache treatment (n = 44) or specialized headache treatment alone (n = 39). The primary treatment outcome was headache days.

RESULTS

Youth and parents in the Internet CBT group demonstrated high levels of engagement with the web program and reported satisfaction with the intervention. Multilevel modelling (MLM) was used to conduct hypothesis testing for continuous outcomes. For our primary treatment outcome of headache days, adolescents reported a statistically significant reduction in headache days from baseline to post-treatment and baseline to 3-month follow-up in both treatment conditions (main effect for time F(2, 136) = 19.70, P < .001). However, there was no statistically significant difference between the Internet CBT group and the specialized headache treatment group at post-treatment or follow-up (group × time interaction F(2, 134) = 0.94, P = .395). For our secondary treatment outcomes, findings from MLM showed that adolescents in both groups demonstrated statistically significant improvement headache pain intensity, activity limitations, depressive symptoms, and parent protective behaviors from baseline to post-treatment and these gains were maintained at 3-month follow-up. Adolescent anxiety symptoms and sleep did not change during the study period for either group. There were no statistically significant group differences on any secondary outcomes at post-treatment or follow-up (P > .05 for all outcomes). No adverse events were reported.

CONCLUSION

Although adjunctive Internet CBT did not lead to additional benefit in this population, future research should evaluate whether it is an effective intervention for adolescents with headache who are unable to access specialized headache treatment.

Psychological therapies (remotely delivered) for the management of chronic and recurrent pain in children and adolescents

BACKGROUND

Chronic pain is common during childhood and adolescence and is associated with negative outcomes such as increased severity of pain, reduced function (e.g. missing school), and low mood (e.g. high levels of depression and anxiety). Psychological therapies, traditionally delivered face-to-face with a therapist, are efficacious at reducing pain intensity and disability. However, new and innovative technology is being used to deliver these psychological therapies remotely, meaning barriers to access to treatment such as distance and cost can be removed or reduced. Therapies delivered with technological devices, such as the Internet, computer-based programmes, smartphone applications, or via the telephone, can be used to deliver treatment to children and adolescents with chronic pain.

OBJECTIVES

To determine the efficacy of psychological therapies delivered remotely compared to waiting-list, treatment-as-usual, or active control treatments, for the management of chronic pain in children and adolescents.

SEARCH METHODS

We searched four databases (CENTRAL, MEDLINE, EMBASE, and PsycINFO) from inception to June 2014 for randomised controlled trials of remotely delivered psychological interventions for children and adolescents (0 to 18 years of age) with chronic pain. We searched for chronic pain conditions including, but not exclusive to, headache, recurrent abdominal pain, musculoskeletal pain, and neuropathic pain. We also searched online trial registries for potential trials. A citation and reference search for all included studies was conducted.

SELECTION CRITERIA

All included studies were randomised controlled trials that investigated the efficacy of a psychological therapy delivered remotely via the Internet, smartphone device, computer-based programme, audiotapes, or over the phone in comparison to an active, treatment-as-usual, or waiting-list control. We considered blended treatments, which used a combination of technology and face-to-face interaction. We excluded interventions solely delivered face-to-face between therapist and patient from this review. Children and adolescents (0 to 18 years of age) with a primary chronic pain condition were the target of the interventions. Each comparator arm, at each extraction point had to include 10 or more participants.

DATA COLLECTION AND ANALYSIS

For the analyses, we combined all psychological therapies. We split pain conditions into headache and mixed (non-headache) pain and analysed them separately. Pain, disability, depression, anxiety, and adverse events were extracted as primary outcomes. We also extracted satisfaction with treatment as a secondary outcome. We considered outcomes at two time points: first immediately following the end of treatment (known as 'post-treatment'), and second, any follow-up time point post-treatment between 3 and 12 months (known as 'follow-up'). We assessed all included studies for risk of bias.

MAIN RESULTS

Eight studies (N = 371) that delivered treatment remotely were identified from our search; five studies investigated children with headache conditions, one study was with children with juvenile idiopathic arthritis, and two studies included mixed samples of children with headache and mixed (i.e. recurrent abdominal pain, musculoskeletal pain) chronic pain conditions. The average age of children receiving treatment was 12.57 years.For headache pain conditions, we found one beneficial effect of remotely delivered psychological therapy. Headache severity was reduced post-treatment (risk ratio (RR) = 2.65, 95% confidence interval (CI) 1.56 to 4.50, z = 3.62,p < 0.01, number needed to treat to benefit (NNTB) = 2.88). For mixed pain conditions, we found only one beneficial effect: psychological therapies reduced pain intensity post-treatment (standardised mean difference (SMD) = -0.61, 95% CI -0.96 to -0.25, z = 3.38, p < 0.01). No effects were found for reducing pain at follow-up in either analysis. For headache and mixed conditions, there were no beneficial effects of psychological therapies delivered remotely for disability post-treatment and a lack of data at follow-up meant no analyses could be run. Only one analysis could be conducted for depression outcomes. We found no beneficial effect of psychological therapies in reducing depression post-treatment for headache conditions. Only one study presented data in children with mixed pain conditions for depressive outcomes and no data were available for either condition at follow-up. Only one study presented anxiety data post-treatment and no studies reported follow-up data, therefore no analyses could be run. Further, there were no data available for adverse events, meaning that we are unsure whether psychological therapies are harmful to children who receive them. Satisfaction with treatment is described qualitatively.'Risk of bias' assessments were low or unclear. We judged selection, detection, and reporting biases to be mostly low risk for included studies. However, judgements made on performance and attrition biases were mostly unclear.

AUTHORS' CONCLUSIONS

Psychological therapies delivered remotely, primarily via the Internet, confer benefit in reducing the intensity or severity of pain after treatment across conditions. There is considerable uncertainty around these estimates of effect and only eight studies with 371 children contribute to the conclusions. Future studies are likely to change the conclusions reported here. All included trials used either behavioural or cognitive behavioural therapies for children with chronic pain, therefore we cannot generalise our findings to other therapies. However, satisfaction with these treatments was generally positive. Larger trials are needed to increase our confidence in all conclusions regarding the efficacy of remotely delivered psychological therapies. Implications for practice and research are discussed.
