Clinical and Cost Effectiveness of Online Cognitive Behavioral Therapy in Children With Functional Abdominal Pain Disorders

Pathology of pain and its implications for therapeutic interventions

Pain is estimated to affect more than 20% of the global population, imposing incalculable health and economic burdens. Effective pain management is crucial for individuals suffering from pain. However, the current methods for pain assessment and treatment fall short of clinical needs. Benefiting from advances in neuroscience and biotechnology, the neuronal circuits and molecular mechanisms critically involved in pain modulation have been elucidated. These research achievements have incited progress in identifying new diagnostic and therapeutic targets. In this review, we first introduce fundamental knowledge about pain, setting the stage for the subsequent contents. The review next delves into the molecular mechanisms underlying pain disorders, including gene mutation, epigenetic modification, posttranslational modification, inflammasome, signaling pathways and microbiota. To better present a comprehensive view of pain research, two prominent issues, sexual dimorphism and pain comorbidities, are discussed in detail based on current findings. The status quo of pain evaluation and manipulation is summarized. A series of improved and innovative pain management strategies, such as gene therapy, monoclonal antibody, brain-computer interface and microbial intervention, are making strides towards clinical application. We highlight existing limitations and future directions for enhancing the quality of preclinical and clinical research. Efforts to decipher the complexities of pain pathology will be instrumental in translating scientific discoveries into clinical practice, thereby improving pain management from bench to bedside.

Internet-delivered cognitive-behaviour therapy for anxiety related to asthma: study protocol for a randomised controlled trial

INTRODUCTION

There is an established association between asthma and anxiety. The overlap between asthma symptoms and symptoms of anxiety may cause individuals to overestimate their asthma severity and restrict their daily activities leading to a low quality of life. There is currently weak evidence for treatments targeting anxiety related to asthma, but cognitive-behavioural therapy (CBT) has shown some promising but mixed results. The current randomised controlled trial will investigate if exposure-based internet-delivered CBT (Internet-CBT) is more effective than treatment as usual+medical education (TAU+ME) to relieve symptoms of anxiety and asthma control.

METHODS AND ANALYSIS

90 participants will be randomised 1:1 to 8 weeks of Internet-CBT or TAU+ME. The primary outcome, the patient-reported Catastrophising Asthma Scale, will be analysed from baseline to the primary endpoint at 16 weeks using hierarchical linear mixed model of the slope over time. Secondary outcomes, such as asthma control, quality of life and forced expiratory volume in 1 s, will be analysed correspondingly.

ETHICS AND DISSEMINATION

All participants will be informed about the study and leave their consent before study entry. All results will be analysed at group level and reported through publication in a peer-reviewed scientific journal within the field. The study received ethical approval by the Swedish Ethical Review Authority in January 2020 (ID: 2019-05985; 2022-01117-02).

Cognitive Behavioral Therapy for Symptom Preoccupation Among Patients With Premature Ventricular Contractions: Nonrandomized Pretest-Posttest Study

BACKGROUND

Premature ventricular contractions (PVCs) are a common cardiac condition often associated with disabling symptoms and impaired quality of life (QoL). Current treatment strategies have limited effectiveness in reducing symptoms and restoring QoL for patients with PVCs. Symptom preoccupation, involving cardiac-related fear, hypervigilance, and avoidance behavior, is associated with disability in other cardiac conditions and can be effectively targeted by cognitive behavioral therapy (CBT).

OBJECTIVE

The aim of this study was to evaluate the effect of a PVC-specific CBT protocol targeting symptom preoccupation in patients with symptomatic idiopathic PVCs.

METHODS

Nineteen patients diagnosed with symptomatic idiopathic PVCs and symptom preoccupation underwent PVC-specific CBT over 10 weeks. The treatment was delivered by a licensed psychologist via videoconference in conjunction with online text-based information and homework assignments. The main components of the treatment were exposure to cardiac-related symptoms and reducing cardiac-related avoidance and control behavior. Self-rated measures were collected at baseline, post treatment, and at 3- and 6-month follow-ups. The primary outcome was PVC-specific QoL at posttreatment assessment measured with a PVC-adapted version of the Atrial Fibrillation Effects on Quality of Life questionnaire. Secondary measures included symptom preoccupation measured with the Cardiac Anxiety Questionnaire. PVC burden was evaluated with 5-day continuous electrocardiogram recordings at baseline, post treatment, and 6-month follow-up.

RESULTS

We observed large improvements in PVC-specific QoL (Cohen d=1.62, P<.001) and symptom preoccupation (Cohen d=1.73, P<.001) post treatment. These results were sustained at the 3- and 6-month follow-ups. PVC burden, as measured with 5-day continuous electrocardiogram, remained unchanged throughout follow-up. However, self-reported PVC symptoms were significantly lower at posttreatment assessment and at both the 3- and 6-month follow-ups. Reduction in symptom preoccupation had a statistically significant mediating effect of the intervention on PVC-specific QoL in an explorative mediation analysis.

CONCLUSIONS

This uncontrolled pilot study shows preliminary promising results for PVC-specific CBT as a potentially effective treatment approach for patients with symptomatic idiopathic PVCs and symptom preoccupation. The substantial improvements in PVC-specific QoL and symptom preoccupation, along with the decreased self-reported PVC-related symptoms warrant further investigation in a larger randomized controlled trial.

Effect of cognitive-behavior therapy for children with functional abdominal pain: a meta-analysis

BACKGROUND

Cognitive-Behavior Therapy (CBT) is the validated non-pharmacological treatment for chronic pain in pediatric patients. While some suggested CBT were comparable to the usual care in reducing children's functional abdominal pain. This meta-analysis was designed to systematically review the literature for RCTs that investigated the efficacy of CBT in children with functional abdominal pain (FAP).

METHODS

PubMed, Embase, and the Cochrane library were searched for papers published up to October 2022. Studies applying different CBT delivery methods (in-person, web-based, phone-based) were included in this meta-analysis to evaluate the comprehensive effectiveness of CBT compared with usual care. Weighted and standardized mean difference with the 95% confidence intervals were used for the synthesis of the results. Primary outcome was the decrease of functional disability inventory (FDI) and the secondary outcomes were the decrease of severity in pain intensity, depression, anxiety, gastrointestinal symptoms, and improvement in physical quality of life (QoL).

RESULTS

A total of 10 RCTs with 1187 children were included in the final analysis. The results showed that CBT resulted in better effect in reducing functional disability inventory (SMD=-2.282, 95%CI: -4.537 to -0.027, P = 0.047), pain intensity (SMD=-0.594, 95%CI: -1.147 to -0.040, P = 0.036), and improving QoL (SMD = 14.097, 95%CI: 0.901 to 27.292, P = 0.036) compared with the control groups. Comparable effects were observed in the severity of depression (SMD=-0.493, 95%CI: -1.594 to 0.608, P = 0.380), anxiety (SMD=-0.062, 95%CI: -0.640 to 0.517, P = 0.835), and gastrointestinal symptoms (SMD=-1.096 95%CI: -2.243 to 0.050, P = 0.061) between CBT and usual treatment.

CONCLUSIONS

We observed the differences in post-treatment FAP and pain intensity for children receiving CBT compared with children receiving treatment as usual. CBT in the setting of FAP demonstrates promising developments and highlights the need for future research.

Economic Evaluations of Digital Health Interventions for Children and Adolescents: Systematic Review

BACKGROUND

Digital health interventions (DHIs) are defined as digital technologies such as digital health applications and information and communications technology systems (including SMS text messages) implemented to meet health objectives. DHIs implemented using various technologies, ranging from electronic medical records to videoconferencing systems and mobile apps, have experienced substantial growth and uptake in recent years. Although the clinical effectiveness of DHIs for children and adolescents has been relatively well studied, much less is known about the cost-effectiveness of these interventions.

OBJECTIVE

This study aimed to systematically review economic evaluations of DHIs for pediatric and adolescent populations. This study also reviewed methodological issues specific to economic evaluations of DHIs to inform future research priorities.

METHODS

We conducted a database search in PubMed from 2011 to 2021 using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist. In total, 2 authors independently screened the titles and abstracts of the search results to identify studies eligible for full-text review. We generated a data abstraction procedure based on recommendations from the Panel on Cost-Effectiveness in Health and Medicine. The types of economic evaluations included in this review were cost-effectiveness analyses (costs per clinical effect), cost-benefit analyses (costs and effects expressed in monetary terms as net benefit), and cost-utility analyses (cost per quality-adjusted life year or disability-adjusted life year). Narrative analysis was used to synthesize the quantitative data because of heterogeneity across the studies. We extracted methodological issues related to study design, analysis framework, cost and outcome measurement, and methodological assumptions regarding the health economic evaluation.

RESULTS

We included 22 articles assessing the cost-effectiveness of DHI interventions for children and adolescents. Most articles (14/22, 64%) evaluated interventions delivered through web-based portals or SMS text messaging, most frequently within the health care specialties of mental health and maternal, newborn, and child health. In 82% (18/22) of the studies, DHIs were found to be cost-effective or cost saving compared with the nondigital standard of care. The key drivers of cost-effectiveness included population coverage, cost components, intervention effect size and scale-up, and study perspective. The most frequently identified methodological challenges were related to study design (17/22, 77%), costing (11/22, 50%), and economic modeling (9/22, 41%).

CONCLUSIONS

This is the first systematic review of economic evaluations of DHIs targeting pediatric and adolescent populations. We found that most DHIs (18/22, 82%) for children and adolescents were cost-effective or cost saving compared with the nondigital standard of care. In addition, this review identified key methodological challenges directly related to the conduct of economic evaluations of DHIs and highlighted areas where further methodological research is required to address these challenges. These included the need for measurement of user involvement and indirect effects of DHIs and the development of children-specific, generic quality-of-life outcomes.

Virtual psychoeducation for improvement of pain catastrophizing in pediatric presurgical patients and caregivers: a proof-of-concept study

PURPOSE

Pain catastrophizing (PC) is the tendency to magnify the threat value of pain sensations and is associated with greater postsurgical pain intensity, functional disability, and pain chronicity. Higher parental PC predicts higher chronic postsurgical pain in youth. Treating PC in caregivers and youth prior to surgery may improve recovery and surgical outcomes. We developed and evaluated a psychoeducational workshop addressing PC for presurgical youth and their parents/caregivers. We hypothesized that parent/caregiver and youth PC scores would decrease over time. We also explored preintervention levels of youth anxiety and depression as moderators of outcome.

METHODS

Youth (n = 43) and caregivers (n = 41) attended a virtual, group-based single-session intervention (SSI). Single-session intervention content addressed pain neuroscience, PC, and adaptive coping strategies for managing pain and PC drawn from cognitive-behavioural, acceptance and commitment, and dialectical behaviour therapy approaches. Participants completed questionnaires assessing PC at preintervention, postintervention, and two weeks postsurgery. Youth mood and anxiety were assessed at preintervention.

RESULTS

Caregiver PC scores decreased from pre- to postintervention (P = 0.006), and this was maintained at postsurgery (P = 0.002). Youth PC scores decreased from preintervention to postsurgery, but only for those with higher preintervention anxiety (P = 0.01).

CONCLUSION

Our results provide proof-of-concept support for a virtual SSI targeting caregivers and youth PC during the perioperative period. The present findings highlight the possible need to screen presurgical candidates for symptoms of anxiety. Replication with larger and more diverse samples, and a more robust design are warranted.

Cognitive behavioural therapy for functional abdominal pain disorders in children and adolescents: A systematic review of randomized controlled trials

AIM

Although Cognitive behavioural therapy (CBT) potentially holds efficacy in addressing functional abdominal pain disorders (FAPDs) amongst children and adolescents, the persistent efficacy is uncertain.

METHODS

We searched three databases to identify related randomized controlled trials (RCTs). Meta-analysis was performed using RevMan and Stata. Subgroup analyses were mainly conducted based on follow-up time. The GRADE approach was used to evaluate the certainty of the evidence.

RESULTS

A total of 14 RCTs evaluating 858 patients were included. All RCTs were rated as having a high risk of bias. Compared with control groups, CBT was associated with improvement of general functional impairment (standardized mean difference (SMD) = -0.77, 95% CI [-1.12, -0.42], p < 0.05), higher treatment success (relative risk (RR) = 2.35, 95% CI [1.50, 3.69], p < 0.05), improvement of abdominal pain symptoms (SMD = -0.48, 95% CI [-0.73, -0.23], p < 0.05), QoL (SMD = 0.42, 95% CI [0.20, 0.64], p < 0.05), and psychological states (SMD = -0.95, 95% CI [-1.62, -0.27], p < 0.05).

CONCLUSION

This meta-analysis provides low to moderate quality evidence that CBT could significantly improve clinical outcomes and QoL for children and adolescents with FAPDs with improvement persisting until short-term follow-up. However, there were discrepancies regarding CBT's effects at mid- and long-term follow-up across different outcomes. More high-quality and longer-duration studies are thus warranted to explore the effectiveness of CBT in the future.

A systematic review and meta-analysis of randomized control trials: efficacy of cognitive behavioral therapies for the management of functional and recurrent abdominal pain disorders in children and adolescents

Cognitive behavioral therapy (CBT) is effective for pain relief in children and adolescents with functional abdominal pain disorders (FAPDs). However, few studies have focused on the FAPDs specifically and the medium-term or long-term results of CBT. In this meta-analysis, we investigated the efficacy of CBT in pediatric FAPDs and unclassified chronic or recurrent abdominal pain (CAP and RAP, respectively). We searched the PubMed, Embase, and Cochrane Library databases for related randomized controlled trials until August 2021. Eventually, 10 trials with 872 participants were included. The methodological quality of the studies was assessed, and data on two primary and four secondary outcomes of interest were extracted. We used the standardized mean difference (SMD) to measure the same outcome, and precisions of effect sizes were reported as 95% confidence intervals (CIs). We found that CBT had significantly positive effects on reducing pain intensity immediately (SMD: -0.54 [CI: -0.9, -0.19], p = 0.003), 3 months after the intervention (SMD: -0.55; [CI: -1.01, -0.1], p = 0.02) and 12 months after the intervention (SMD: -0.32; [CI: -0.56, -0.08], p = 0.008). CBT also reduced the severity of gastrointestinal symptoms, depression, and solicitousness, improved the quality of life and decreased the total social cost. Future studies should consider uniform interventions in the control group and comparing different CBT delivery methods.

Irritable bowel syndrome: Epidemiology, overlap disorders, pathophysiology and treatment

Irritable bowel syndrome (IBS) is a common chronic gastrointestinal disease with a significant impact on patients' quality of life and a high socioeconomic burden. And the understanding of IBS has changed since the release of the Rome IV diagnosis in 2016. With the upcoming Rome V revision, it is necessary to review the results of IBS research in recent years. In this review of IBS, we can highlight future concerns by reviewing the results of IBS research on epidemiology, overlap disorders, pathophysiology, and treatment over the past decade and summarizing the latest research.

Home-based guided hypnotherapy for children with functional abdominal pain and irritable bowel syndrome in primary care: study protocol for a randomised controlled trial

INTRODUCTION

Children often present to primary care with functional abdominal pain (FAP) or irritable bowel syndrome (IBS), and around half still have abdominal complaints 1 year later. Hypnotherapy is an evidence-based treatment that is used in specialist care, but it lacks evidence in primary care. This study will investigate the (cost) effectiveness of home-based guided hypnotherapy for children with FAP or IBS in primary care.

METHODS AND ANALYSIS

We report the design of a pragmatic randomised controlled trial among children aged 7-17 years, diagnosed with FAP or IBS by their general practitioner (GP), with assessments over 12 months. The control group will receive care as usual (CAU) by their GP (eg, communication, education and reassurance), while the intervention group will receive CAU plus 3 months of home-based guided hypnotherapy via a website. The primary outcome will be the proportion of children with adequate relief from abdominal pain/discomfort at 12 months, analysed on an intention-to-treat basis. Secondary outcomes will include the adequacy of pain relief at 3 and 6 months, pain/discomfort severity, pain frequency and intensity, daily functioning and impact on function, anxiety and depression, pain beliefs, sleep disturbances, school absence, somatisation, and healthcare use and costs. We must include 200 children to determine a 20% difference in those with adequate relief (55% control vs 75% intervention).

ETHICS AND DISSEMINATION

The Medical Ethics Review Committee of the University Medical Center Groningen, the Netherlands, approved this study (METc2020/237). The results will be disseminated to patients, GPs and other stakeholders via email, a dedicated website, peer-reviewed publications and presentations at national and international conferences. We plan to collaborate with the Dutch Society of GPs to implement the results in clinical practice.

The Cost-Effectiveness of a Dance and Yoga Intervention for Girls with Functional Abdominal Pain Disorders

BACKGROUND

Functional abdominal pain disorders (FAPDs) affect children worldwide, being more prevalent among girls. The individual and societal burdens of the disease are substantial, and evidence-based interventions are needed. Non-pharmacological treatments have generally produced promising results, with dance and yoga specifically having potential as an effective treatment option. Beside efficacy, the cost-effectiveness of interventions is important when prioritizing and allocating public resources.

OBJECTIVE

This study evaluated the cost-effectiveness of an 8-month dance and yoga intervention for girls with functional abdominal pain or irritable bowel syndrome, based on a randomized control trial called 'Just in TIME'.

METHODS

The intervention, performed in Sweden, was studied using a decision analysis tool, i.e., a decision tree within the trial followed by a Markov model with a time horizon of 10 years. The base case considered healthcare costs as well as productivity losses, measuring the effects in gained quality-adjusted life-years (QALYs) and presenting an incremental cost-effectiveness ratio (ICER).

RESULTS

The base case results show that the intervention, compared with current practice, was the dominant strategy from both the 12-month and long-term perspectives. The sensitivity analyses indicated that the long-term, but not the short-term, findings were robust for different assumptions and changes in parameter estimates, resulting in ICERs similar to those of the base case scenario.

CONCLUSIONS

Offering dance and yoga to young girls with FAPDs generates small QALY gains and monetary savings compared with standard healthcare and is likely cost-effective. These findings make a valuable contribution to an area where evidence-based and cost-effective treatment interventions are needed.

"A source of empowerment and well-being": Experiences of a dance and yoga intervention for young girls with functional abdominal pain disorders

Background

Functional abdominal pain disorders are common among children and adolescents worldwide and effective treatments are needed to alleviate suffering for these children and their families. This study aimed to explore the experience of participating in a combined dance and yoga intervention from the perspectives of girls aged 9-13 years with functional abdominal pain disorders.

Materials and Methods

A randomized controlled trial called Just in TIME (Try, Identify, Move and Enjoy) recruited 121 girls aged 9-13 years with functional abdominal pain disorders. The eight-month intervention combined dance and yoga twice a week, focusing on enjoyment, socialization and playful creativity in an undemanding and non-judgemental environment. The intervention group comprised 64 girls, of whom 25 were purposefully selected for this qualitative interview study. Semi-structured interviews were conducted and analysed using qualitative content analysis with an inductive approach.

Results

The girls' experiences of the Just in TIME intervention can be described as "A source of empowerment and well-being which facilitated personal growth and new ways of engaging in life". The main category was derived from six generic categories: "A sense of belonging", "Joy and emotional expression through movement", "Relief from pain", "More self-confident", "More active in daily life" and "A sense of calm."

Conclusions

Regular participation in an eight-month intervention with combined dance and yoga in a supportive and non-judgemental atmosphere can ease pain and strengthen inner resources, resulting in empowerment, well-being and a more active life for girls with functional abdominal pain disorders.

Parental responses and catastrophizing in online cognitive behavioral therapy for pediatric functional abdominal pain: A mediation analysis of a randomized controlled trial

Objective

To test if decreased parental protective behaviors, monitoring behaviors, and parental catastrophizing mediate relief of gastrointestinal symptoms in children 8-12 years with functional abdominal pain disorders (FAPDs). The study uses secondary data analyses of a randomized controlled trial in which exposure-based online cognitive behavioral therapy (ICBT) was found superior to treatment as usual in decreasing gastrointestinal symptoms.

Methods

The ICBT included 10 weekly modules for children and 10 weekly modules for parents. Treatment as usual consisted of any medication, dietary adjustments, and healthcare visits that the participants engaged in during 10 weeks. All measures were self-assessed online by parents. Biweekly assessments of the Adult Responses to Children's Symptoms (ARCS), Protect and Monitor subscales, and the Pain Catastrophizing Scale, parental version (PCS-P) were included in univariate and multivariate growth models to test their mediating effect on the child's gastrointestinal symptoms assessed with the Pediatric Quality of Life Gastrointestinal Symptoms Scale (PedsQL).

Results

A total of 90 dyads of children with FAPDs and their parents were included in the study, of which 46 were randomized to ICBT and 44 to treatment as usual. The PCS-P was found to mediate change in the PedsQL ab = 0.639 (95% CI 0.020-2.331), while the ARCS Monitor ab = 0.472 (95% CI -1.002 to 2.547), and Protect ab = -0.151 (95% CI -1.455 to 0.674) were not mediators of change.

Conclusions

To target parental catastrophizing in ICBT for pediatric FAPDs is potentially important to reduce abdominal symptoms in children.

Psychosocial Interventions for the Treatment of Functional Abdominal Pain Disorders in Children: A Systematic Review and Meta-analysis

IMPORTANCE

Functional abdominal pain disorders (FAPDs) can severely affect the life of children and their families, with symptoms carrying into adulthood. Management of FADP symptoms is also a financial and time burden to clinicians and health care systems.

OBJECTIVE

To systematically review various randomized clinical trials (RCTs) on the outcomes of cognitive behavioral therapy (CBT), educational support, yoga, hypnotherapy, gut-directed hypnotherapy, guided imagery, and relaxation in the management of FAPDs.

DATA SOURCES

PubMed, MEDLINE, Embase, PsycINFO, and Cochrane Library.

STUDY SELECTION

All RCTs that compared psychosocial interventions with any control or no intervention, for children aged 4 to 18 years with FAPDs.

DATA EXTRACTION AND SYNTHESIS

Pairs of the authors independently extracted data of all included studies, using a predesigned data extraction sheet. One author acted as arbitrator. Risk of bias was assessed using the Cochrane risk of bias tool, and certainty of the evidence for all primary outcomes was analyzed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) framework.

MAIN OUTCOMES AND MEASURES

Primary outcomes were treatment success, pain frequency, pain intensity, and withdrawal owing to adverse events. Dichotomous outcomes were expressed as risk ratio (RR) with corresponding 95% CIs. Continuous outcomes were expressed as mean difference (MD) or standardized MD with 95% CI.

RESULTS

A total of 33 RCTs with 2657 children (median [range] age, 12 [7-17] years; 1726 girls [67.3%]) were included. Twelve studies compared CBT with no intervention, 5 studies compared CBT with educational support, 3 studiescompared yoga with no intervention, 2 studies compared hypnotherapy with no intervention, 2 studies compared gut-directed hypnotherapy with hypnotherapy, and 2 studies compared guided imagery with relaxation. Seven studies evaluated other unique comparisons (eg, visceral osteopathy vs normal osteopathy). Per the GRADE framework, owing to risk of bias, there was moderate certainty in evidence that CBT was associated with higher treatment success numbers (n = 324 children; RR, 2.37; 95% CI 1.30-4.34; number needed to treat [NNT] = 5), lower pain frequency (n = 446 children; RR, -0.36; 95% CI, -0.63 to -0.09), and lower pain intensity (n = 332 children; RR, -0.58; 95% CI, -0.83 to -0.32) than no intervention. Owing to high imprecision, there was low certainty in evidence that there was no difference between CBT and educational support for pain intensity (n = 127 children; MD, -0.36; 95% CI, -0.87 to 0.15). Owing to risk of bias and imprecision, there was low certainty in evidence that hypnotherapy resulted in higher treatment success compared with no intervention (n = 91 children; RR, 2.86; 95% CI, 1.19-6.83; NNT = 5). Owing to risk of bias and imprecision, there was low certainty in evidence that yoga had similar treatment success to no intervention (n = 99 children; RR, 1.09; 95% CI, 0.58-2.08).

CONCLUSIONS AND RELEVANCE

Results of this systematic review and meta-analysis suggest that CBT and hypnotherapy may be considered as a treatment for FAPDs in childhood. Future RCTs should address quality issues to enhance the overall certainty of the results, and studies should consider targeting these interventions toward patients who are more likely to respond.

Validation of child-adapted short scales for measuring gastrointestinal-specific avoidance and anxiety

Aim

To validate child‐adapted shortened versions of the Irritable Bowel Syndrome‐Behavioural Responses Questionnaire (IBS‐BRQ; short scale denoted BRQ‐C) and the Visceral Sensitivity Index (VSI; short scale denoted VSI‐C) for children with functional abdominal pain disorders (FAPDs).

Methods

A child psychologist supervised by a child gastroenterologist was responsible for shortening the scales (BRQ‐C, 11 items; and VSI‐C, 7 items). Then, a sample of 89 children aged 8–12 years with FAPDs was used in the validation. Construct validity was assessed with correlations. Measures included gastrointestinal symptoms, quality of life, pain intensity and anxiety. Also, internal consistency, test–retest reliability, administration time and factor structure were assessed.

Results

Internal consistency for the BRQ‐C and the VSI‐C was α = 0.84 and α = 0.80, respectively. Correlations with related scales were similar between child‐adapted scales and original scales, indicating construct validity equivalence. Correlations between short scales and original scales were high. Mean administration time was reduced by 47% (BRQ‐C) and 42% (VSI‐C), compared with original scales. Test–retest reliability was r = 0.72 for BRQ‐C and r = 0.83 for VSI‐C. BRQ‐C had two factors (Avoidance and Bowel control). VSI‐C had a unifactorial structure.

Conclusion

The BRQ‐C and the VSI‐C were found to be time‐saving, reliable and valid for children with FAPDs.

Non-pharmacological management of pediatric functional abdominal pain disorders: Current evidence and future perspectives

Functional abdominal pain disorders (FAPDs) are an important and prevalent cause of functional gastrointestinal disorders among children, encompassing the diagnoses of functional dyspepsia, irritable bowel syndrome, abdominal migraine, and the one not previously present in Rome III, functional abdominal pain not otherwise specified. In the absence of sufficiently effective and safe pharmacological treatments for this public problem, non-pharmacological therapies emerge as a viable means of treating these patients, avoiding not only possible side effects, but also unnecessary prescription, since many of the pharmacological treatments prescribed do not have good efficacy when compared to placebo. Thus, the present study provides a review of current and relevant evidence on non-pharmacological management of FAPDs, covering the most commonly indicated treatments, from cognitive behavioral therapy to meditation, acupuncture, yoga, massage, spinal manipulation, moxibustion, and physical activities. In addition, this article also analyzes the quality of publications in the area, assessing whether it is possible to state if non-pharmacological therapies are viable, safe, and sufficiently well-based for an appropriate and effective prescription of these treatments. Finally, it is possible to observe an increase not only in the number of publications on the non-pharmacological treatments for FAPDs in recent years, but also an increase in the quality of these publications. Finally, the sample selection of satisfactory age groups in these studies enables the formulation of specific guidelines for this age group, thus avoiding the need for adaptation of prescriptions initially made for adults, but for children use.

Effect of Whole-Course Continuous Nursing Intervention Combined with a Nursing Practice Teaching Method on Quality of Life of Children with Functional Dyspepsia and Parents’ Satisfaction Based on Smart Health

With the development of information technology, it has become a part of people’s lives. WeChat is not only a popular chatting tool in daily life but can also be used in the medical field. Functional dyspepsia is a common pediatric disease, with complex pathogenic factors, which are usually attributed to abnormal gastric acid secretion and gastrointestinal dysfunction. In our research, we aim to investigate the effects of whole-course continuous nursing intervention combined with a nursing practice teaching method on the quality of life (QOL) of children with functional dyspepsia and parents’ satisfaction. One hundred and twenty children with functional dyspepsia admitted to our hospital (February 2019–February 2020) were retrospectively analyzed and equally divided into the experimental group (EG) and the control group (CG) according to the order of admission. The CG received whole-course continuous nursing intervention, and the EG received whole-course continuous nursing intervention combined with the nursing practice teaching method. Children’s psychological states and QOL and parents’ satisfaction of both groups were compared. After discharge, compared with the CG, the negative emotion scores in the EG were remarkably lower ( $P<0.001$ ). After discharge, compared with the CG, the QOL scores ( $P<0.001$ ), the proportion of children with good and excellent QOL ( $P<0.05$ ), and parents’ satisfaction ( $P<0.001$ ) in the EG were remarkably higher. For children with functional dyspepsia, whole-course continuous nursing intervention combined with the nursing practice teaching method can improve their negative emotions, QOL, and parents’ satisfaction, which should be popularized in practice.

Subcortical-Cortical Functional Connectivity as a Potential Biomarker for Identifying Patients with Functional Dyspepsia

The diagnosis of functional dyspepsia (FD) presently relies on the self-reported symptoms. This study aimed to determine the potential of functional brain network features as biomarkers for the identification of FD patients. Firstly, the functional brain Magnetic Resonance Imaging data were collected from 100 FD patients and 100 healthy subjects, and the functional brain network features were extracted by the independent component analysis. Then, a support vector machine classifier was established based on these functional brain network features to discriminate FD patients from healthy subjects. Features that contributed substantially to the classification were finally identified as the classifying features. The results demonstrated that the classifier performed pretty well in discriminating FD patients. Namely, the accuracy of classification was 0.84 ± 0.03 in cross-validation set and 0.80 ± 0.07 in independent test set, respectively. A total of 15 connections between the subcortical nucleus (the thalamus and caudate) and sensorimotor cortex, parahippocampus, orbitofrontal cortex were finally determined as the classifying features. Furthermore, the results of cross-brain atlas validation showed that these classifying features were quite robust in the identification of FD patients. In summary, the current findings suggested the potential of using machine learning method and functional brain network biomarkers to identify FD patients.

Internet-delivered cognitive behavioral therapy for youth with functional abdominal pain: a randomized clinical trial testing differential efficacy by patient subgroup

ABSTRACT

Inconsistent results of psychological treatments for pediatric functional abdominal pain (FAP) may be due to heterogeneity of patients' pain-related psychological characteristics. This randomized controlled trial tested whether statistically derived patient subgroups (high pain dysfunctional [HPD], high pain adaptive [HPA], and low pain adaptive [LPA]) moderated response to cognitive behavior therapy (CBT) for adolescents with FAP and their parents (n = 278 dyads; patients were 66% female, mean [SD] age was 14.62 [1.88] years, and parents were 95% female). Randomization to Internet-delivered CBT vs Internet-delivered pain education (EDU) was stratified by patient subgroup. Follow-up assessments of gastrointestinal (GI) symptoms (primary outcome), abdominal pain, and pain interference were at midtreatment, posttreatment, 6 months, and 12 months. Data were analysed using linear mixed effects models. Significant treatment × subgroup × time interaction effects showed that patient subgroup significantly moderated the effect of treatment on GI symptoms (t[853 = -2.93, P = 0.003) and abdominal pain (t(844) = -2.14, P = 0.03) across the treatment period. Among HPD youth, those in CBT had significantly greater GI symptom reduction than those in EDU through posttreatment. By contrast, among HPA and LPA youth, symptom improvement did not differ by treatment condition. Furthermore, among all patients assigned to CBT, HPD youth demonstrated significantly greater reductions in GI symptoms compared with HPA and LPA youth and greater reductions in abdominal pain compared with LPA youth. All subgroups maintained symptom reductions throughout the follow-up period. Results suggest that subgrouping FAP patients may inform treatment allocation and optimize treatment response.

Cognitive behavioral treatment for irritable bowel syndrome: a recent literature review

Irritable bowel syndrome (IBS) is a gastrointestinal psychosomatic disorder that often develops and worsens with stress. Hence, it is important to treat it from both, its physical and mental aspects. We reviewed recent research on cognitive-behavioral therapy (CBT)—one of the most widely studied psychological treatments for IBS—since it focuses on addressing the cognitions and behaviors associated with IBS symptoms, and combines diverse content, such as cognitive techniques, exposure, stress management, and mindfulness, whose effects have been widely studied. Research on CBT for IBS varies not only in terms of content of the interventions, but also in terms of implementation (individual or group, face-to-face or online). Internet-delivered CBT has recently shown the possibility of providing more accessible and cost-effective psychological intervention to IBS patients in formats, other than face-to-face. In recent years, many standardized scales that allow for IBS-specific psychological assessments have been used in clinical studies of CBT for IBS. Tools that competently deliver effective interventions and properly measure their effectiveness are expected to spread to many people suffering from IBS.

Engagement during a Mixed In-Person and Remotely Delivered Psychological Intervention for Youth with Functional Abdominal Pain Disorders and Anxiety

Functional abdominal pain disorders (FAPD) are common disabling pain conditions frequently associated with co-occurring mental health problems such as anxiety. Psychological therapies such as cognitive behavioral therapy (CBT) have been shown to be effective. Therefore, it is important to understand participant engagement (i.e., use of intervention tools) to such approaches, and if engagement impacts treatment response. The Aim to Decrease Anxiety and Pain Treatment (ADAPT) is an effective psychological treatment approach using a blend of in-person sessions and interventionist phone support with self-paced web modules to manage pain and anxiety. The current study used a mixed-methods approach to investigate micro-level and macro-level participant engagement during the ADAPT program. In-person/phone session attendance was high (>95%) although scheduling adjustments were common (25.5%). Varied levels of engagement with web tools were observed. Thematic analysis also revealed variability in patterns of use. Additionally, while participants indicated they generally understood how to use certain skills (e.g., problem solving, detective thinking), and these skills were effective in managing symptoms during treatment, these activities were generally underutilized. Further, participant engagement did not predict response to the ADAPT intervention. These findings are important as the demand for accessible psychotherapeutic tools to manage pain and anxiety is likely to remain high.

Does Quantitative Sensory Testing Improve Prediction of Chronic Pain Trajectories? A Longitudinal Study of Youth With Functional Abdominal Pain Participating in a Randomized Controlled Trial of Cognitive Behavioral Treatment

OBJECTIVES

Youth with functional abdominal pain (FAP) experience significant pain-related distress and functional impairment. Although quantitative sensory testing protocols have identified alterations in pain modulatory systems that distinguish youth with FAP from healthy controls, the extent to which evoked pain responses predict subsequent trajectories of pain symptoms and disability over and above established psychosocial risk factors is unclear.

METHODS

The present study included 183 adolescents with FAP who were enrolled in a randomized controlled trial comparing an 8-week, internet-delivered program of cognitive behavior therapy (n=90) or pain education (n=93). Participants completed a quantitative sensory testing protocol before the intervention and were followed for 12-month posttreatment.

RESULTS

Whereas adolescents with FAP who exhibited stronger baseline conditioned pain modulation (CPM) reported decreases in pain-related interference over follow-up (b=-0.858, SE=0.396, P=0.032), those with weaker CPM exhibited high, relatively stable levels of pain-related interference over time (b=-0.642, SE=0.400, P=0.110). CPM status predicted changes in pain-related interference after controlling for the effects of treatment condition and psychosocial risk factors. Static measures of pain sensitivity (ie, pain threshold, pain tolerance) and temporal summation of second pain were not associated with changes in measures of abdominal pain, gastrointestinal symptom severity, or pain-related interference over follow-up.

DISCUSSION

The present findings contribute to a growing literature on the predictive utility of quantitative sensory testing indices and suggest that CPM may complement existing psychosocial risk measures in determining individualized pain-related risk profiles.

An Update on the Assessment and Management of Pediatric Abdominal Pain

Chronic abdominal pain is very common in children and adolescent and results in high personal and social costs. Most youth with chronic abdominal pain fulfill criteria for a functional abdominal pain disorder (FAPD) as defined by Rome criteria. These are complex conditions with a wide array of biological, psychological, and social factors contributing to the experience of pain. The purpose of the current review is to provide an overview of the pathophysiology of FAPDs and an up-to-date summary of the literature related to FAPDs in children and adolescents, with additional focus on several areas (eg, diet and probiotics) where patients and families frequently have questions or implement self-directed care. We also provide an approach to the assessment and treatment of pediatric FAPDs focusing on the robust literature regarding psychological interventions and much sparser literature regarding medication treatment.

Online multidisciplinary interventions for paediatric chronic pain: A content analysis

BACKGROUND

Many online interventions for paediatric chronic pain have been developed and evaluated. In accordance with the biopsychosocial model, the recommended treatment approach for chronic pain is multidisciplinary. Despite this, multidisciplinary components within existing online interventions have not been examined. The objective of the present review was to summarise and evaluate the content of existing online interventions for paediatric chronic pain by mapping intervention content to evidence-based guidelines for chronic pain management.

METHODS

Interventions were identified using an updated systematic review. Nine chronic pain management strategies that reflect evidence-based guidance for multidisciplinary chronic pain management were defined by the authors, examples of which include 'pain education', 'activity pacing' and 'physiotherapy'. Identified interventions were then coded against the target strategies. These codes were compiled descriptively to provide an overview of how well each chronic pain management strategy was represented across the dataset, and which interventions represented the most strategies.

RESULTS

Thirty-five articles, relating to 13 unique interventions for paediatric chronic pain management were identified; few encompassed a complete multidisciplinary approach. Many CBT-based interventions included multidisciplinary elements. Across interventions, physiotherapy and non-pharmacological physical therapies were the least represented chronic pain management strategies.

CONCLUSIONS

The content analysis revealed a lack of online interventions encompassing complete multidisciplinary pain management. It is important that new interventions for paediatric chronic pain management are evidence-based and reflect current best practice guidelines. Established intervention development approaches should be utilised and include a process evaluation to help identify which intervention components are effective in which contexts.

SIGNIFICANCE

This content analysis of online interventions for paediatric chronic pain highlights the need for multidisciplinary practices in pain management to be translated into online interventions. Improving the availability of pain management resources is essential for many families who cannot attend specialist pain clinics, particularly in the context of the COVID-19 pandemic. There is potential for new resources, as well as for established resources, to be further developed to deliver a broader range of pain management content.

Targeting excessive avoidance behavior to reduce anxiety related to asthma: A feasibility study of an exposure-based treatment delivered online

There is an established relationship between anxiety and asthma, which is associated with poor health outcomes. Most previous cognitive behavior therapies (CBT) have focused on comorbid panic disorder whereas anxiety related to asthma may rather be illness-specific. The feasibility of an online CBT targeting avoidance behavior in anxiety related to asthma was evaluated, using a pretest-posttest design. Thirty participants with self-reported anxiety related to asthma were offered an eight-week treatment with therapist support. Mean adherence was good (80% of content), and most participants (89%) reported adequate relief after treatment. Catastrophizing about asthma (CAS), assessed at 2 months after treatment, improved significantly with a large effect size (Cohen's d = 1.52). All secondary outcomes, including asthma control, avoidance behavior, fear of asthma symptoms and quality of life, improved significantly with moderate to large effect sizes (d: 0.40-1.44). All improvements were stable at 4 months follow up. Weekly ratings showed that a decrease in avoidance behavior predicted a decrease in CAS the following week throughout the treatment period. We conclude that CBT targeting avoidance behavior is a feasible treatment for anxiety related to asthma. The results justify investigation of efficacy and mechanisms of change in a randomized controlled trial. ClinicalTrials.gov, ID: NCT03486756.

Predicting pain: differential pain thresholds during self-induced, externally induced, and imagined self-induced pressure pain

Supplemental Digital Content is Available in the Text.

Imagining pressure pain to be self-induced led to increased pressure pain thresholds. Such sensory attenuation of pain was also seen in actual self-induced pressure.

During self-induced pain, a copy of the motor information from the body's own movement may help predict the painful sensation and cause downregulation of pain. This phenomenon, called sensory attenuation, enables the distinction between self-produced stimuli vs stimuli produced by others. Sensory attenuation has been shown to occur also during imagined self-produced movements, but this has not been investigated for painful sensations. In the current study, the pressure pain thresholds of 40 healthy participants aged 18 to 35 years were assessed when pain was induced by the experimenter (other), by themselves (self), or by the experimenter while imagining the pressure to be self-induced (imagery). The pressure pain was induced on the participants left lower thigh (quadriceps femoris) using a handheld algometer. Significant differences were found between all conditions: other and self (P < 0.001), other and imagery (P < 0.001), and self and imagery (P = 0.004). The mean pressure pain threshold for other was 521.49 kPa (SE = 38.48), for self 729.57 kPa (SE = 32.32), and for imagery 618.88 kPa (SE = 26.67). Thus, sensory attenuation did occur both in the self condition and the imagery condition. The results of this study may have clinical relevance for understanding the mechanisms involved in the elevated pain thresholds seen in patients with self-injury behavior and the low pain thresholds seen in patients with chronic pain conditions. Imagery of sensory attenuation might also be used to alleviate the pain experience for patients undergoing procedural pain.

Internet-Delivered Exposure-Based Therapy for Symptom Preoccupation in Atrial Fibrillation: Uncontrolled Pilot Trial

BACKGROUND

Atrial fibrillation (AF) is the most common cardiac arrhythmia in the adult population. AF is associated with a poor quality of life (QoL) and, in many patients, current medical treatments are inadequate in alleviating AF symptoms (eg, palpitations). Patients often present with symptom preoccupation in terms of symptom fear, avoidance, and control behaviors. Internet-delivered cognitive behavior therapy is effective for treating other somatic disorders but has never been evaluated in patients with AF.

OBJECTIVE

The aim of this study is to evaluate the efficacy and feasibility of AF-specific internet-delivered cognitive behavior therapy.

METHODS

We conducted an uncontrolled pilot study in which 19 patients with symptomatic paroxysmal AF underwent internet-delivered cognitive behavior therapy. Participants completed self-assessments at pretreatment, posttreatment, and at a 6-month follow-up along with handheld electrocardiogram measurements with symptom registration. The treatment lasted 10 weeks and included exposure to physical sensations, reduction in avoidance behavior, and behavioral activation.

RESULTS

We observed large within-group improvements in the primary outcome, AF-specific QoL (Cohen d=0.80; P<.001), and in symptom preoccupation (Cohen d=1.24; P<.001) at posttreatment; the results were maintained at the 6-month follow-up. Treatment satisfaction and adherence rates were also high. We observed an increased AF burden, measured by electrocardiogram, at the 6-month follow-up, but a significant decrease was observed in the overestimation of AF symptoms at posttreatment and 6-month follow-up. Exploratory mediation analysis showed that a reduction in symptom preoccupation mediated the effects of internet-delivered cognitive behavior therapy on AF-specific QoL.

CONCLUSIONS

This study presents preliminary evidence for the potential efficacy and feasibility of a novel approach in treating patients with symptomatic AF with internet-delivered cognitive behavior therapy.

Medical Management of Chronic Pancreatitis in Children: A Position Paper by the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition Pancreas Committee

ABSTRACT

This position paper summarizes the current understanding of the medical management of chronic pancreatitis (CP) in children in light of the existing medical literature, incorporating recent advances in understanding of nutrition, pain, lifestyle considerations, and sequelae of CP. This article complements and is intended to integrate with parallel position papers on endoscopic and surgical aspects of CP in children. Concepts and controversies related to pancreatic enzyme replacement therapy (PERT), the use of antioxidants and other CP medical therapies are also reviewed. Highlights include inclusion of tools for medical decision-making for PERT, CP-related diabetes, and multimodal pain management (including an analgesia ladder). Gaps in our understanding of CP in children and avenues for further investigations are also reviewed.

Breaking the vicious circle of fear and avoidance in children with abdominal pain: A mediation analysis

OBJECTIVES

Exposure-based cognitive behavioral therapy via internet (Internet-CBT) has been shown to reduce symptoms and increase quality of life for children with functional abdominal pain disorders (FAPDs), but the mechanisms of change are unknown. The objective was to examine whether a change in symptom-specific fear and avoidance, i.e., gastrointestinal-specific anxiety (GI-anxiety) and gastrointestinal-specific avoidance (GI-avoidance), mediated changes in parent-reported abdominal symptoms for children receiving Internet-CBT compared with children receiving treatment as usual. A further aim was to assess if baseline levels of the proposed mediators moderated the mediation.

METHODS

Weekly assessments of child-reported mediators and parent-reported outcome from 90 children aged 8-12 who were included in a randomized controlled trial were used in univariate and multivariate growth models to test the direct effect of treatment on outcome and the indirect effects via mediators and moderated mediation.

RESULTS

Treatment condition significantly predicted the slope of the mediators (a-path), in favor of Internet-CBT, and mediators were correlated with the outcome (b-path). The indirect effects of the mediators on the outcome (cross-product of the a and b-paths) were significantly different from zero for both GI-avoidance, ab = 1.43, 95%CI [0.42, 3.23]; and GI-anxiety ab = 1.58, 95%CI [0.43, 3.62]. Baseline levels of the proposed mediators moderated the size of the mediation.

CONCLUSIONS

GI-anxiety and GI-avoidance were mediators of change in Internet-CBT and high levels of the mediators at baseline were associated with larger mediated effects. Healthcare professionals should be aware of, and inform families about, the potential benefits of reducing symptom-specific fear and avoidance.

Paediatric functional abdominal pain disorders

Paediatric functional abdominal pain disorders, currently referred to as disorders of gut-brain interaction, comprise irritable bowel syndrome, functional dyspepsia, abdominal migraine and functional abdominal pain not otherwise specified, as defined by the Rome IV diagnostic criteria. Functional abdominal pain disorders are common disorders with a prevalence of 3-16% depending on country, age and sex. A greater understanding of aetiopathogenesis and pathophysiology is emerging and includes intestinal components (inflammation, motility and the microbiota), central factors (psychological aspects, sensitization and/or differences in connectivity or activity of certain brain regions) as well as extrinsic factors (infections). In particular, the timing of disruption of the microbiota-gut-brain axis seems to be important. Diagnosis is challenging but is primarily based on clinical symptoms and exclusion of other organic causes, with an emphasis on avoiding unnecessary invasive diagnostic procedures. The available pharmacological interventions are limited in children and, therefore, management has focused on combined approaches, including mind-targeted interventions (hypnotherapy and cognitive behavioural therapy), diet (probiotics) and percutaneous electrical nerve field stimulation. The evidence for their clinical efficacy, although limited, is favourable, with positive impacts on symptoms and overall quality of life. The coming decades hold promise for improved understanding and management of these enigmatic disorders.

Functional gastrointestinal disorders in children: What is new?

Abdominal pain-predominant functional gastrointestinal disorders encompass a group of chronic conditions featuring abdominal pain where no serious gastrointestinal or intra-abdominal pathology is present. The Rome IV classification system defines and categorises this group based on symptomatology as: functional dyspepsia, irritable bowel syndrome, functional abdominal pain - not otherwise specified and abdominal migraine. These conditions can impact the functioning of the child and family significantly and are challenging to manage. Although the causes of these conditions are not clear, recent years have seen an improved understanding of underlying pathophysiology and identification of effective management options for these conditions.

Exposure-based cognitive behavior therapy for anxiety related to asthma: A feasibility study with multivariate baseline design

In the presence of asthma, the risk of having an anxiety disorder is increased twofold. The few trials conducted on cognitive behavior therapy (CBT) for anxiety and asthma have mainly targeted panic disorder, and with mixed results. Experimental laboratory research indicates that increased anxiety may lead to hypervigilance toward asthma. Hence, fear and avoidance associated with increased anxiety due to asthma may be an important treatment target. A treatment that learn participants to differentiate between anxiety and asthma through gradual exposure to situations that risk triggering anxiety for asthma may be a possible avenue. As a first step to investigate this issue further, we developed a 10-week exposure-based CBT protocol for anxiety related to asthma and tested it in six participants using multivariate baseline design with repeated assessments throughout treatment. All participants reported satisfaction with treatment, as well as subjective overall improvement after treatment. Visual analysis, using graphs over each individual's trajectory, as well as potential efficacy on group level analyzing standardized mean change, indicated improvements in important outcomes. We conclude that exposure-based CBT is feasible and may improve anxiety related to asthma. Further investigation under randomized controlled trial conditions is warranted.

Internet-based cognitive behavioural therapy programme as an intervention for people diagnosed with adult-onset, focal, isolated, idiopathic cervical dystonia: a feasibility study protocol

Background

Dystonia is one of the most common forms of movement disorder, caused by the co-contraction of antagonistic muscles, leading to abnormal postures and considerable disability. Non-motor symptoms, notably psychiatric disorders, are well recognised comorbid features of the disorder. However, there is no standardised model for the management of these symptoms in dystonia, with them frequently going undiagnosed and untreated. An internet-based cognitive behavioural therapy programme may provide a future model of care that also maximises available resources.

Methods

This study represents a two-armed randomised feasibility trail, aiming to recruit a total of 20 participants with a diagnosis of adult-onset primary focal cervical dystonia. Participants will be recruited from the Global Myoclonus Dystonia Registry and Dystonia Non-Motor Symptom Study (conducted at Cardiff University) based on presence of moderate symptoms of anxiety/depression as indicated by standardised questionnaires. All participants will undergo assessment at baseline, 3 and 6 months, with this including questionnaires for assessment of non-motor symptoms and clinical assessment of motor symptom severity. Participants will be randomised to either the control (n = 10) or treatment (n = 10) groups. The treatment group will be asked to complete one session of the online CBT program a week, for 8 weeks. The primary outcome measure will be the engagement of participants with the programme, with secondary outcomes of non-motor and motor symptom scores.

Discussion

Promising results have been shown using face-to-face cognitive behavioural therapy to reduce levels of anxiety and depression in individuals with a diagnosis of dystonia. However, no studies to date have sought to determine the feasibility of an internet-delivered cognitive behavioural therapy programme. A number of effective internet-based programmes have been developed that combat anxiety and depression in the general population, suggesting the potential for its effectiveness in cervical dystonia patients. Success with this study would significantly impact the clinical care delivery for patients with cervical dystonia, as well as widening potential access to effective treatment.

Digital Approaches to Remote Pediatric Health Care Delivery During the COVID-19 Pandemic: Existing Evidence and a Call for Further Research

The global spread of the coronavirus disease (COVID-19) outbreak poses a public health threat and has affected people worldwide in various unprecedented ways, both personally and professionally. There is no question that the current global COVID-19 crisis, now more than ever, is underscoring the importance of leveraging digital approaches to optimize pediatric health care delivery in the era of this pandemic. In this perspective piece, we highlight some of the available digital approaches that have been and can continue to be used to streamline remote pediatric patient care in the era of the COVID-19 pandemic, including but not limited to telemedicine. JMIR Pediatrics and Parenting is currently publishing a COVID-19 special theme issue in which investigators can share their interim and final research data related to digital approaches to remote pediatric health care delivery in different settings. The COVID-19 pandemic has rapidly transformed health care systems worldwide, with significant variations and innovations in adaptation. There has been rapid expansion of the leveraging and optimization of digital approaches to health care delivery, particularly integrated telemedicine and virtual health. Digital approaches have played and will play major roles as invaluable and reliable resources to overcome restrictions and challenges imposed during the COVID-19 pandemic and to increase access to effective, accessible, and consumer-friendly care for more patients and families. However, a number of challenges remain to be addressed, and further research is needed. Optimizing digital approaches to health care delivery and integrating them into the public health response will be an ongoing process during the current COVID-19 outbreak and during other possible future pandemics. Regulatory changes are essential to support the safe and wide adoption of these approaches. Involving all relevant stakeholders in addressing current and future challenges as well as logistical, technological, and financial barriers will be key for success. Future studies should consider evaluating the following research areas related to telemedicine and other digital approaches: cost-effectiveness and return on investment; impact on quality of care; balance in use and number of visits needed for the management of both acute illness and chronic health conditions; system readiness for further adoption in other settings, such as inpatient services, subspecialist consultations, and rural areas; ongoing user-centered evaluations, with feedback from patients, families, and health care providers; strategies to optimize health equity and address disparities in access to care related to race and ethnicity, socioeconomic status, immigration status, and rural communities; privacy and security concerns for protected health information with Health Insurance Portability and Accountability Act (HIPAA)-secured programs; confidentiality issues for some specific populations, especially adolescents and those in need of mental health services; early detection of exposure to violence and child neglect; and integration of training into undergraduate and graduate medical education and subspecialty fellowships. Addressing these research areas is essential to understanding the benefits, sustainability, safety, and optimization strategies of telemedicine and other digital approaches as key parts of modern health care delivery. These efforts will inform long-term adoption of these approaches with expanded dissemination and implementation efforts.

Dyadic Psychosocial eHealth Interventions: Systematic Scoping Review

BACKGROUND

Dyadic psychosocial interventions have been found beneficial both for people coping with mental or physical health conditions as well as their family members and friends who provide them with support. Delivering these interventions via electronic health (eHealth) may help increase their scalability.

OBJECTIVE

This scoping review aimed to provide the first comprehensive overview of dyadic eHealth interventions for individuals of all ages affected by mental or physical illness and their family members or friends who support them. The goal was to understand how dyadic eHealth interventions have been used and to highlight areas of research needed to advance dyadic eHealth intervention development and dissemination.

METHODS

A comprehensive electronic literature search of PubMed, EMBASE, Cochrane, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO was conducted for articles published in the English language through March 2019. Eligible records described a psychosocial eHealth intervention that intervened with both care recipients and their support person.

RESULTS

A total of 7113 records were reviewed of which 101 met eligibility criteria. There were 52 unique dyadic eHealth interventions identified, which were tested across 73 different trials. Of the unique interventions, 33 were conducted among dyads of children and their supporting parent, 1 was conducted with an adolescent-young adult care recipient population, and the remaining 18 were conducted among adult dyads. Interventions targeting pediatric dyads most commonly addressed a mental health condition (n=10); interventions targeting adult dyads most commonly addressed cancer (n=9). More than three-fourths of interventions (n=40) required some human support from research staff or clinicians. Most studies (n=64) specified one or more primary outcomes for care recipients, whereas less than one-fourth (n=22) specified primary outcomes for support persons. Where specified, primary outcomes were most commonly self-reported psychosocial or health factors for both care recipients (n=43) and support persons (n=18). Results of the dyadic eHealth intervention tended to be positive for care recipients, but evidence of effects for support persons was limited because of few studies specifying primary outcomes for supporters. Trials of dyadic eHealth interventions were most commonly randomized controlled trials (RCTs; n=44), and RCTs most commonly compared the dyadic eHealth intervention to usual care alone (n=22).

CONCLUSIONS

This first comprehensive review of dyadic eHealth interventions demonstrates that there is substantial, diverse, and growing literature supporting this interventional approach. However, several significant gaps were identified. Few studies were designed to evaluate the unique effects of dyadic interventions relative to individual interventions. There was also limited assessment and reporting of outcomes for support persons, and there were no interventions meeting our eligibility criteria specifically targeting the needs of older adult dyads. Findings highlight areas of research opportunities for developing dyadic eHealth interventions for novel populations and for increasing access to dyadic care.

Brain-Gut Therapies for Pediatric Functional Gastrointestinal Disorders and Inflammatory Bowel Disease

PURPOSE OF REVIEW

The purpose of this review is to discuss current knowledge of brain-gut therapies (BGT) in pediatric functional gastrointestinal disorders (FGID) and inflammatory bowel disease (IBD), including their evidence base, the common psychopathology that they address, and the integration of this knowledge into medical settings.

RECENT FINDINGS

Cognitive behavioral therapy (CBT), hypnotherapy (HT), mindfulness-based therapy (MBT), and exposure-based therapy (EBT) have the most data supporting their use in children, particularly in FGID, more so than in IBD. This difference is most likely because of the increased role of psychological factors in FGID, though these same factors can be seen comorbidly in IBD. Integrative BGT treatment strategies with the collaboration of clinicians across disciplines may provide the most benefit to patients. This review details our current understanding of the evidence for BGT in pediatric FGID and IBD and how they may best be used in treatment strategies.
