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

Trajectories of change in pediatric functional abdominal pain disorders during Internet cognitive behavior therapy: A single case experimental study

Functional abdominal pain disorders (FAPDs) are prevalent in youth and affect daily life. Therapist-supported Internet-delivered cognitive-behavioral-therapy (ICBT) is promising, though the detailed trajectories of therapeutic effects unknown. This study aimed to analyze trajectories of effect and timing of changes in abdominal symptoms (primary outcome) and psychological factors (catastrophizing, avoidance and control behavior, pain acceptance (secondary outcomes)) in children and adolescents during 10 weeks of exposure-based ICBT for FAPDs in a randomized multiple-baseline single-case experimental design study in six children and six adolescents with FAPDs, referred from pediatric departments. Outcomes were assessed daily during baseline (A), treatment (B1: Main treatment components, B2: Training repeated exposures), and three-month follow-up (C). Effects were evaluated with visual analyses, Tau-U effect sizes for each individual, and multilevel modeling for group-level effects. All participants completed all treatment modules. Individually, treatment effectively reduced abdominal symptoms in half of the participants at three-month follow-up, following diverse trajectories with varying sequences of secondary outcome changes. At group-level, children demonstrated significant effects on estimated means of all outcomes at follow-up (P<0.05), while adolescents did on all outcomes (P<0.05) except one pain acceptance item (pain control). The group trajectories differed: children showed significant daily changes in abdominal symptoms during treatment B2, while adolescents exhibited significant slopes in most outcomes except one pain acceptance item (pain control) as early as during treatment B1. The findings support the effect of ICBT for FAPDs in youth, although with varying effect trajectories and differences in the timing of outcome changes across individuals and age-groups. PERSPECTIVES: This study provides evidence for the effect of ICBT in managing FAPDs in children and adolescents while uncovering individual and age-related differences in trajectories of changes in abdominal symptoms and psychological factors. Clinicians and researchers can use these findings to refine treatment protocols and explore mechanisms underlying these variations. CLINICAL TRIAL PREREGISTRATION: NCT05237882.

Non-Cognitive Behavioral Therapy Psychological Interventions May Not Make the Difference in Children and Adolescents With Chronic Pain

Background and Aim

Chronic pain in pediatric populations presents a multifaceted challenge with biopsychosocial impact, requiring a multidisciplinary approach including psychological treatment. At our interdisciplinary pain center, the SARS-CoV-2 pandemic-related disruptions led to the cessation of cognitive-behavioral therapy (CBT) and other psychological interventions during the pandemic. The aim of this retrospective cohort study with secondary retrospective matched case-control analysis was to evaluate the impact of interruption of non-CBT psychological interventions, namely psychoanalysis and psychodynamic psychotherapy, on children and adolescents with chronic pain conditions during the SARS-CoV-2 pandemic.

Materials and Methods

We included pediatric patients with primary and secondary chronic pain conditions evaluated by our team during the SARS-CoV-2 pandemic. We excluded patients who did not receive psychological intervention when available, those with incomplete data on initial evaluation or follow-up, and those who received outside psychiatric care or individual or group CBT. The primary outcome was a Patients' Global Impression of Change (PGIC) score of 6-7. Secondary outcome measures were pain intensity, use of pain medication, sleep, physical function, school attendance, the incidence of suicidality, and the reason for end of treatment.

Results

The study included 146 patients, 77 who received non-CBT psychological interventions and 69 who did not receive any psychological interventions. We found no meaningful difference between the use of non-CBT psychological intervention and no treatment in the incidence of PGIC 6-7 points, pain intensity, school attendance, physical function, suicidality, and cause of end of treatment. Patients not receiving any psychological interventions were more likely to have normalized sleep at the end of treatment.

Conclusion

Non-CBT psychological interventions, namely psychoanalysis and psychodynamic psychotherapy, were not associated with meaningful benefits for children and adolescents with chronic pain during the COVID-19 pandemic. Patients who did not receive psychological interventions reported normalization of their sleep at the end of treatment compared to those who participated in non-CBT interventions.

Moderators of digital cognitive-behavioral therapy for youth with sickle cell disease pain: secondary analysis of a randomized controlled trial

ABSTRACT

Pain is the hallmark symptom of sickle cell disease (SCD). By adolescence, 20% of youth with SCD develop chronic SCD pain. Our randomized controlled trial found significant reductions in pain in youth receiving digital cognitive-behavioral therapy (CBT) vs education control. However, little is known about factors that moderate the effects of CBT in adolescents with SCD. This secondary data analysis aims to identify adolescent and family characteristics that moderate treatment effects on pain outcomes in 111 adolescents aged 12 to 18 with SCD (M = 14.9, SD = 1.9, girls = 59%) and their caregivers. Adolescents were randomly assigned to digital CBT (N = 57) or education control (N = 54). Digital CBT included separate content for parents/caregivers (ie, a website to learn problem-solving skills and behavioral and communication strategies) and youths (ie, a smartphone app and website to learn pain management skills). Outcomes were assessed at pretreatment, posttreatment (2 months), and follow-up (6 months). Potential moderators included pretreatment variables (ie, adolescent variables: age, executive functioning, anxiety, depression; parent variables: psychological distress, protective behaviors, family functioning). There was a significant overall effect modification on pain intensity outcomes from pretreatment parent psychological distress (P = 0.012), where CBT appeared more effective among those with elevated parental distress. Differential intervention effects were observed across multiple potential moderator groups, though most of these differences did not reach statistical significance. Our study underscores the importance of family factors in understanding the efficacy of digital CBT for adolescent SCD pain, pointing to the need for future research to optimize CBT through targeted family-focused strategies.

Effectiveness of Non-Pharmacological Interventions in the Management of Pediatric Chronic Pain: A Systematic Review

(1) Background: Chronic pain in children remains an under-researched area, especially compared to acute pain. This systematic review aims to evaluate the effectiveness of non-pharmacological interventions in the management of pediatric chronic pain and their impact on the well-being of both children and their families. Given the growing interest in integrative treatments to reduce reliance on pharmacological solutions, this review addresses the need for alternative therapeutic approaches. (2) Methods: A systematic review was conducted following the PRISMA guidelines, covering studies published between 2019 and 2024 from PubMed, Cochrane Library, Web of Science, and Scopus. Eligible studies included children aged 2 to 18 years with chronic pain who received non-pharmacological interventions. Data were extracted on intervention types, participant characteristics, and outcomes. The risk of bias was assessed using RoB2 for randomized trials and ROBINS-I for non-randomized studies. (3) Results: A total of 11 studies involving 1739 children were included, assessing interventions such as cognitive behavioral therapy, personalized psychosocial follow-up programs, hypnotherapy, music therapy, and digital tools. The results demonstrated significant reductions in pain severity, improvements in emotional and physical well-being, and high patient satisfaction. However, the generalizability of findings was limited by the small sample sizes and variability in study designs. (4) Conclusions: Non-pharmacological interventions appear effective in managing pediatric chronic pain, offering improvements in pain reduction and quality of life. Further research is needed to optimize these approaches and confirm their long-term benefits across diverse populations. These interventions represent promising alternatives or complements to pharmacological treatments in pediatric pain management.

The Effectiveness of Pain Science Education on Caregiver and Children's Knowledge, Beliefs, Attitudes, and Behaviors-A Systematic Review and Meta-Analysis

Pain science education (PSE) can be used as part of treatment and prevention for chronic pain in children. We assessed the effectiveness of PSE on knowledge, beliefs, attitudes, and behaviors in children and the people that care for children. We set a minimum criterion for education to address pain biology knowledge. We included studies aimed at both treatment and prevention of chronic pain. We conducted searches using 5 databases. We assessed the risk of bias using the Cochrane Risk of Bias 2 tool. Data were pooled using a random-effects meta-analysis or assessed using a narrative synthesis. The certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation. We screened 14,505 records and included 7 studies involving 351 caregivers and 1,285 children. Four studies were included in meta-analyses. We found low-certainty evidence that PSE has a large beneficial effect on caregiver knowledge and beliefs compared with alternative education (standardized mean difference = 1.14 [95% confidence interval: .88-1.42]; I2 = 0%). We found no difference in functional disability in children with chronic pain after PSE (Functional Disability Inventory score mean difference = .73 [95% confidence interval: -.81 to 2.27; I = 0%]). Narrative syntheses showed low-certainty evidence for improved knowledge and beliefs in children with preventative and treatment effects. Overall, we found few studies, and along with high risk of bias, this significantly contributed to the low certainty of findings. The effect of learning pain science for both preventative and treatment effects in children, carers, and the child/carer dyad remains mostly unknown. This review was prospectively registered with The international Prospective register of systematic reviews (CRD42022344382) on July 22, 2022. PERSPECTIVE: This review examines the effect of PSE on pain-related knowledge, beliefs, attitudes, and behaviors in children and the people that care for children (0-18). The findings contribute to knowledge about pain treatments and health promotion for caregivers and their children with and without chronic pain.

Pain Catastrophizing Moderates the Relationship Between Pain Sensitivity and Clinical Pain in Adolescents With Functional Abdominal Pain

Pain catastrophizing has been linked to amplified pain sensitivity assessed using quantitative sensory testing (QST) in adults; pediatric data are limited, particularly in youth with functional abdominal pain (FAP). With increasing use of QST to evaluate somatosensory function and predict pain outcomes, we examined the associations between QST and clinical pain in adolescents with FAP and tested the moderating effects of pain catastrophizing. Seventy-seven adolescents (mean age 16.6 years, 85.7% female, 72.7% White, 90.8% non-Hispanic) who fulfilled diagnostic criteria for FAP completed QST assessment (pressure pain threshold and tolerance, heat pain threshold, conditioned pain modulation) and measures of abdominal pain intensity, pain interference, and pain catastrophizing. Adjusting for age and sex, only higher heat pain threshold was associated with higher abdominal pain intensity (Beta per 1-standard deviation = .54, P = .026). Contrary to hypothesis, for youth with higher pain catastrophizing, higher pressure pain tolerance was associated with greater abdominal pain intensity, but associations were not significant for youth with lower catastrophizing (P = .049). Similarly, for those with higher pain catastrophizing (in contrast to lower pain catastrophizing), higher pressure pain thresholds and tolerance were associated with higher pain interference (P = .039, .004, respectively). Results highlight the need to investigate the influence of pain catastrophizing on QST. PERSPECTIVE: This study demonstrated unexpected findings of pain catastrophizing moderating the relationships between pressure pain threshold and tolerance, and clinical pain in adolescents with FAP. This raised questions regarding our understanding of psychological contributions to QST findings in pediatric populations with chronic pain.

Evolution of Parent-Targeted Interventions for Pain-Predominant Disorders of Gut-Brain Interactions: Research and Clinical Practice Considerations

Objective

Abdominal pain-related Disorders of Gut-Brain Interaction (DGBIs) in children are best understood from a biopsychosocial model, including particular attention to the child's environment. Interventions have begun to increasingly target parents as important agents of change in this population. The purpose of this manuscript is to summarize the evolution of parent-targeted interventions for pediatric pain-related DGBIs and provide recommendations for application of the model to clinical practice.

Methods

A topical review of literature regarding parent-targeted interventions and related factors in the treatment of pediatric pain-related DGBIs was conducted, followed by a discussion of these findings to clinical practice settings.

Results

A growing body of research has supported parent-targeted interventions in the treatment of pediatric pain-related disorders of gut-brain interactions (DGBI), although translation of these findings to practice settings is complicated by numerous factors. Strategies for obtaining physician buy-in and parental engagement are discussed, as are potential logistical considerations of multiple caregivers, child age, and billing considerations.

Conclusions

There is a promising and growing evidence-base for parent-targeted interventions for pain-related DGBIs, which have not yet been widely adopted into clinical practice recommendations. Engaging all stake-holders and attending to the nuances of this approach are recommended to successfully apply parent-targeted interventions into clinical practice settings.

Efficacy of Cognitive Behavioral Therapy With Local Wisdom and Web-Based Counseling on Generalized Anxiety Disorders and Functional Gastrointestinal Disorders in Adolescent College Girls: Protocol for a Randomized Controlled Trial

BACKGROUND

The high academic demands experienced by students will often have an impact on the quality of their mental and physical health. The most common health problems reported are gastrointestinal disorders. This condition tends to manifest in the emergence of generalized anxiety disorders (GADs) and reduces the quality of life and productivity. The population that experiences this disorder the most is female adolescents, and this condition occurs in both South African and Indonesian populations. The use of drugs, especially benzodiazepines, often causes psychological conditions as side effects. For this reason, it is necessary to have a solution in the form of a targeted and efficient approach to reduce psychological symptoms that arise from functional gastrointestinal disorders (FGIDs) in the form of anxiety.

OBJECTIVE

The purpose of this study is to produce and implement a counseling intervention model to assist female students with GADs caused by FGID factors using an approach combining cognitive behavioral therapy (CBT), web-based counseling, and local wisdom in Indonesian and South African populations.

METHODS

The research subjects will comprise 118 female adolescent students from Indonesia and 118 female adolescent students from South Africa, making a total sample of 236 participants, and the study will use a prospective, parallel randomized controlled trial design. The recruitment process will begin in July 2023, and the trial will begin in August 2023. The posttest assessment data gathering will take place by November 2023. Questionnaires that will be used in this study include the Functional Gastrointestinal Disorder Checklist (FGI-Checklist) to collect data related to FGIDs and the Generalized Anxiety Disorder 7-item (GAD-7) to measure the anxiety conditions experienced by respondents.

RESULTS

By adopting the intention-to-treat principle, there will be significant mean changes in GAD scores and FGID scores after exposure to this combined approach in the Indonesian and South African populations. Implementing this comprehensive intervention will improve the students' psychological symptoms related to FGIDs and ultimately enhance their overall well-being.

CONCLUSIONS

This study will develop and implement a model of counseling intervention for female students with GADs obtained from FGIDs using a combination approach to CBT, web-based counseling, and local wisdom in both the Indonesian and South African populations. The trial findings will contribute to our understanding of the effects of CBT combined with local wisdom and web-based counseling approaches that mental health counselors can use to treat GAD-affected adolescent girls who have FGIDs.

Psychological treatment for pediatric functional abdominal pain disorders

PURPOSE OF REVIEW

The purpose of this review is to discuss up-to-date psychological treatment strategies for functional abdominal pain disorders (FAPDs) with practical implications for primary care providers who are the "front line" of treatment for pediatric FAPD.

RECENT FINDINGS

Positive diagnosis, pain education, and access to multidisciplinary care improve outcomes for FAPD patients. Cognitive behavioral therapy (CBT) and hypnosis continue to have the strongest evidence in psychological treatments, but educational interventions and other nonpharmacological approaches show promise as well. There are innovative programs that combine these tools into group or internet-based treatments to expand access to care. Additionally, nonpharmacological tools, including neurostimulation and virtual reality programs, are increasing in popularity.

SUMMARY

FAPD is prevalent across pediatric practices, yet there is no standard medical or dietary approach, and there are many barriers to diagnosis and treatment. It is important for patients to have positive encounters around diagnosis and education, access to multidisciplinary care, and integrated psychological support. Consistently, studies show that psychology continues to be a vital component of care. This review discusses supported uses of psychology, innovative programming for increasing access to care, and how primary care providers can incorporate lessons learned from psychology in FAPD care.

A therapeutic guide on pediatric irritable bowel syndrome and functional abdominal pain-not otherwise specified

Disorders of the gut-brain interaction negatively impact quality of life and carry a substantial socioeconomic burden. Irritable bowel syndrome (IBS) and functional abdominal pain-not otherwise specified (FAP-NOS) are common functional abdominal pain disorders in childhood. The pathophysiology is not fully understood, and high-quality intervention trials and international guidelines are missing. Therefore, the management of these disorders remains challenging. This review aims to provide an up-to-date overview of therapeutic possibilities for pediatric IBS or FAP-NOS and recommends management strategies. To prevent unnecessary referrals and extensive costs, it is fundamental to make a positive diagnosis of IBS or FAP-NOS in children with chronic abdominal pain with only minimal investigations. A tailor-made approach for each patient, based on the accompanying physical and psychological symptoms, is proposed to date.

CONCLUSION

Shared decision-making including non-pharmacological and pharmacological interventions should be considered and discussed with the family.

WHAT IS KNOWN

• Irritable bowel syndrome and functional abdominal pain-not otherwise specified are common in childhood. • Although the number of treatment options has grown recently, managing these disorders can be challenging and unsatisfactory, and no evidence-based international management guidelines are available.

WHAT IS NEW

• We suggest using a stepwise individualized approach to management, where after first-line management, both non-pharmacological and pharmacological interventions should be discussed.

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.

Place and Pain: Association Between Neighborhood SES and Quantitative Sensory Testing Responses in Youth With Functional Abdominal Pain

OBJECTIVE

Neighborhood socioeconomic status (SES) is linked to self-reported pain severity and disability but its association with evoked pain responsiveness in individuals with chronic pain remains unclear. The present study examined relations between neighborhood SES, assessed through the area deprivation index (ADI), and static and dynamic pain response indices. It was hypothesized that youth with functional abdominal pain (FAP) living in lower SES neighborhoods would exhibit lower pain threshold, lower pain tolerance, and reduced conditioned pain modulation (CPM) compared to youth living in higher SES neighborhoods.

METHODS

Participants were 183 youth with FAP and their parents. Youth completed a quantitative sensory testing protocol. Family addresses were used to compute ADI scores. Thermal stimuli for pain threshold and tolerance were delivered to participants' forearms using thermodes. CPM, an index of descending pain inhibition, was determined using a thermode as test stimulus and a hot water bath as conditioning stimulus.

RESULTS

As hypothesized, youth with FAP living in lower SES neighborhoods exhibited weaker CPM. Contrary to hypotheses, lower neighborhood SES was associated with neither pain thresholds nor with pain tolerance.

CONCLUSIONS

These findings demonstrated the independent contribution of place of residence-an often neglected component of the biopsychosocial model-to efficiency of descending pain inhibition. Understanding the mechanisms that account for such associations between place and pain could guide the development of public health and policy initiatives designed to mitigate chronic pain risk in underserved and economically marginalized communities.
