Functional abdominal pain in childhood: background studies and recent research trends

Children's Beliefs about Pain: An Exploratory Analysis

Functional abdominal pain (FAP) is one of the most common childhood medical complaints, associated with significant distress and impairment. Little is known about how children understand their pain. Do they attribute it to personal weakness? Do they perceive pain as having global impact, affecting a variety of activities? How do they cope with pain? We explored the pain beliefs of 5- to 9-year-old children with FAP using a novel Teddy Bear Interview task in which children answered questions about a Teddy bear's pain. Responses were analyzed quantitatively and qualitatively. Results indicate that the majority of young children with FAP are optimistic about pain outcomes. Children generated many types of coping strategies for Teddy's pain and adjusted their calibration of Teddy's pain tolerance dependent on the activity being performed. Early warning signs also emerged: a subset of children were pessimistic about Teddy's pain, and several children identified coping strategies that, while developmentally appropriate, could lead to excessive help seeking if not intervened upon (e.g., physician consultation and shot). The Teddy Bear Interview allows children to externalize their pain, making it a useful tool to access cognitive pain constructs in younger children. Thus, these findings highlight the importance of early intervention for childhood FAP.

Functional abdominal pain in adolescents: case-based management

Functional gastrointestinal disorders (FGIDs), including functional abdominal pain (FAP), account for a large portion of conditions seen by paediatric gastroenterologists. Despite the commonality of FGIDs, there remains significant stigma around these diagnoses among medical providers, patients and families. This is due to the absence of easily identifiable biological markers in FGIDs and the overlay with psychological and social factors contributing to symptom onset and maintenance. As such, the biopsychosocial model is essential in conceptualising, evaluating and treating FGIDs. The way in which medical providers explain FGIDs and the manner in which they collaborate with other specialists (eg, psychologists, dieticians, physical therapists, school nurses) is paramount to the patient and family acceptance of an FGID diagnosis and the success of subsequent treatment. The following review outlines paediatric FGIDs with a focus on FAP in adolescents, in particular within the context of the biopsychosocial approach to pathophysiology, diagnosis and treatment.

Understanding the Experience of Functional Abdominal Pain Through Written Narratives by Families

OBJECTIVE

Although functional abdominal pain (FAP) is one of the most common pain problems in children, there is a lack of qualitative studies on this topic. Our aim was to increase knowledge in this field by testing an innovative written narrative methodology designed to approach the experiences of children with FAP and their parents.

METHODS

We analyzed the FAP experiences of 39 families who completed a written narrative task (children and parents separately). Some of the families (N = 20) had previously completed an online psychosocial intervention, whereas others had not, because a complementary objective was to explore possible differences between parent and child narratives, and between those who had and had not completed the intervention.

RESULTS

Families wrote about abdominal pain (characteristics, triggers, pain consequences, and coping strategies), their well-being, the diagnostic process, future expectations, and the positive effects of an online psychosocial intervention. Children tended to mention pain characteristics more, whereas parents tended to write more about triggers and the diagnostic process.

CONCLUSIONS

A written narrative methodology was found to be a useful approach for understanding families' experiences. Results confirmed that FAP affects families at the emotional, behavioral, and social levels and that an online psychosocial intervention can help families.

Effects and Experiences of Families Following a Web-Based Psychosocial Intervention for Children with Functional Abdominal Pain and Their Parents: A Mixed-Methods Pilot Randomized Controlled Trial

Purpose

To evaluate post-treatment efficacy of DARWeb (online psychosocial intervention for children with functional abdominal pain) using a randomized clinical trial design and combining quantitative and qualitative data.

Patients and methods

Twenty-five families with children with FAP in the experimental group (EG: accessed to DARWeb) and 36 in the control group (CG: wait-list) were compared. Children and parents completed measures of abdominal pain severity (primary outcome), quality of life, and satisfaction. Moreover, children completed measures of depression, functional disability, catastrophizing and coping strategies; parents completed measures about parental responses to their children's pain. Families also answered open questions and were interviewed.

Results

A higher percentage of children in the EG achieved a significant clinical change in abdominal pain severity from the parents' perspective (28% in the EG vs 8.33% in the CG). There was a significantly greater reduction in pain frequency in the EG compared to the CG (both from the children's and parents' perspectives) from mixed repeated-measures analyses of variance (there was not a significant interaction in total scores of pain severity). A higher percentage of children in the EG improved in quality of life and depression compared to the CG (results from mixed methods repeated-measures analyses of variances were not significant). However, there were no differences for disability, pain catastrophizing or the coping strategies assessed from the children's perspective; neither from the parents' assessment of quality of life. There were significant interactions for parents' solicitousness responses and promotion of well behaviors in the expected directions. Families were quite satisfied with the intervention, and the qualitative results confirmed an improvement in pain and having learned important coping strategies.

Conclusion

Our results support the efficacy of our intervention, but future studies are needed with different profiles of initial severity of the pain problem, longer follow-ups, and other conditions.

Quantitative and qualitative testing of DARWeb: An online self-guided intervention for children with functional abdominal pain and their parents

The main objective of this study was to preliminary explore the effects of DARWeb on different outcomes. A Quasi-experimental, one-group, pretest-posttest design was used. Parents and children were asked to complete questionnaires and questions (separately) about quality of life, abdominal pain severity, and satisfaction. Semi-structured interviews with families were also performed. This study focuses on 17 families. Results showed that parent's ratings of children's abdominal pain severity were significantly lower after finishing the intervention and at the 3-month follow-up, and quality of life scores had increased significantly after 3 months. From children's ratings, mean abdominal pain severity scores were significantly lower after the intervention compared to the preintervention assessment. Both parents and children were quite satisfied with the intervention. In qualitative interviews, families suggested that DARWeb helped them to give less importance to pain and to learn coping strategies. In conclusion, this study showed the potential usefulness of DARWeb for children with functional abdominal pain and for their parents.

Systematic review of childhood and adolescent risk and prognostic factors for persistent abdominal pain

This review aimed to identify childhood and adolescence risk and prognostic factors associated with onset and persistence of persistent abdominal pain and related disability and assess quality of the evidence. While findings suggest a possible role for negative emotional symptoms and parental mental health as risk and prognostic factors for onset and persistence of persistent abdominal pain, the evidence is of poor quality overall and nonexistent when it comes to prognostic factors associated with disability.

CONCLUSION

Further research is needed to increase confidence in existing evidence and to explore new factors. This research will inform prevention.

Therapeutic Response for Functional Abdominal Pain in Children with Occult Constipation: Laxatives versus Prokinetic Drugs

The relationship between functional abdominal pain (FAP) and occult constipation (OC) in children who did not meet the Rome III criteria for constipation has rarely been reported. This study aimed to estimate the prevalence of OC in patients with FAP and to compare the effectiveness of prokinetic drugs and laxatives for FAP and OC. Pediatric outpatients (n = 212; aged 4-15 years) who satisfied the Rome III criteria for childhood FAP were divided into 2 groups based on Leech scores: group 1 < 8; group 2 ≥ 8. Group 2 received either prokinetic drugs or laxatives and pain severity was assessed after 2 weeks, 1 month, and 3 months. A total 52.4% (111/212) of patients had OC in this study. More patients who received laxatives had reduced pain scores compared with those who received prokinetic drugs. Those treated with laxatives in group 2 had a better response than those treated with prokinetic drugs throughout the study period (P < 0.001, P < 0.001, and P = 0.002 after 2 weeks, 1 month, and 3 months, respectively). OC was frequently encountered in children with FAP. Laxatives can be more effective than prokinetic drugs for relieving symptoms of FAP in children with a Leech score ≥ 8 and suspected OC.

Mind Over Gut: Psychosocial Management of Pediatric Functional Abdominal Pain

INTRODUCTION

Functional abdominal pain (FAP) refers to a common set of symptoms that characterizes abdominal pain for which there is no identifiable organic disease process. FAP is associated with functional disability, but understanding of its pathogenesis is incomplete. The condition appears to stem from an interaction between physical and psychological mechanisms.

METHOD

A literature search was conducted to explore the psychosocial management of FAP and the role of nurse practitioners in treatment.

RESULTS

A growing body of evidence supports the efficacy of psychosocial interventions, including cognitive behavioral therapy, hypnotherapy, and multidisciplinary treatment programs. There are no randomized controlled trials at the primary care level to guide management.

DISCUSSION

Nurse practitioners can provide the supportive and consistent patient-provider relationship that is integral to the management and treatment of FAP. More research is necessary to understand how best to incorporate behavioral interventions into primary care practice.

Eating behaviors and quality of life in preadolescents at risk for obesity with and without abdominal pain

OBJECTIVES

We evaluated eating behaviors and quality of life (QOL) in preadolescent children at risk for obesity, with and without abdominal pain (AP).

METHODS

Participants were parent-child dyads enrolled in a randomized, controlled obesity prevention trial. The children were between 5 and 10 years of age and at risk for obesity (70th-95th percentile of body mass index, n = 420). Parents completed measures of their child's eating behaviors, QOL, AP, and bowel function and their own depression status, concern about child weight, and feeding practices. Children's height and weight were also measured.

RESULTS

Children with frequent AP (≥2/month, n = 103) were compared with children reporting infrequent AP (<2/month, n = 312). Age and body mass index did not differ between groups, but AP was more prevalent in girls. Child emotional overeating and parental depression scores were higher in the frequent AP group (P < 0.01), and child QOL was lower (P < 0.01). In multivariable analysis, female gender (odds ratio [OR] 2.18, 95% confidence interval [CI] 1.20-3.97), emotional overeating (OR 2.28, 95% CI 1.37-3.81), and parental depression (OR 1.23, 95% CI 1.12-1.35) were associated with more frequent AP. Secondary analyses were completed for children who met Rome III criteria for irritable bowel syndrome.

CONCLUSIONS

Clinicians working with children with AP at risk for obesity should consider assessing for and, when appropriate, addressing parent and child factors that could exacerbate AP.
