Importance of addressing anxiety in youth with functional abdominal pain: suggested guidelines for physicians

Psychological distress and coping efficacy in children with disorders of gut-brain interaction

BACKGROUND

Multiple psychological factors influence disorders of gut-brain interaction (DGBIs). We aimed to evaluate psychological distress in Colombian schoolchildren with and without DGBIs.

METHODS

We included children ages 8-18 years without organic medical conditions from largest regional public schools in Colombia. Children completed Spanish versions of Rome III diagnostic questionnaire for DGBIs, State Trait Anxiety Inventory for Children (STAIC), Children's Somatization Inventory (CSI), and a measure of coping efficacy. These data, demographic and socioeconomic characteristics, were compared between children with DGBIs and healthy peers. Exploratory analyses investigated differences between youth with symptoms of functional abdominal pain disorders (FAPDs) compared with healthy peers.

KEY RESULTS

Of 1496 children, 281 (mean age 12.9 ± 2.2 years, 49.8% females) self-reported criteria for DGBIs and 125 reported (44.5%) FAPDs. Children with DGBIs had higher trait anxiety, emotional sensitivity, somatization including GI, non-GI, pain-related, and non-pain-related subscales (p < 0.001 each) and lower coping efficacy (p = 0.02) compared to healthy peers. Females had higher trait anxiety and somatization (p = 0.04 and p = 0.005, respectively). State and trait anxiety and coping efficacy differed based on location in children with DGBIs (p = 0.02, p = 0.03, and p < 0.001, respectively). Children with FAPDs had higher trait anxiety (p = 0.02) and somatization (p < 0.001) compared to healthy youth.

CONCLUSIONS & INFERENCES

Children with DGBIs had higher anxiety, emotional sensitivity, and somatization, and lower coping efficacy compared with healthy youth. This highlights the importance of appraising psychological distress characteristics as well as incorporating conflict resolution, assertiveness training, and resilience building during the treatment of DGBIs.

The burden and impact of recurrent abdominal pain – exploring the understanding and perception of children and their parents

Background: Recurrent abdominal pain (RAP) is a common complaint for children and can result in a significantly lower quality of life due to the extent it can interfere with normal life. RAP can also significantly impact the quality of life of parents. This study sought to qualitatively explore parents’ and children’s understanding and perceptions of the burden and impact of RAP.

Methods: Semi-structured interviews were conducted with a sample of parent/child dyads or families (N = 5) engaging with a psychology service.

Findings: The findings of the inductive thematic analysis revealed four emergent themes common to both parents and children: (1) Perception, understanding and identification of RAP, (2) Contributing factors, (3) Coping mechanisms/pain management strategies, and (4) Impact and burden of RAP.

Conclusions: These findings have important clinical implications regarding the identification and management of RAP and may also contribute to improving communication between clinicians, parents and children by providing insight from multiple perspectives into how RAP is experienced.

Amygdalar functional connectivity during resting and evoked pain in youth with functional abdominal pain disorders

ABSTRACT

Pediatric functional abdominal pain disorders (FAPD) are highly prevalent, difficult to diagnose, and challenging to treat. The brain systems supporting FAPD remain poorly understood. This investigation examined the neuromechanisms of FAPD during a well-tolerated visceral pain induction task, the water load symptom provocation task (WL-SPT). Youth between the ages of 11 and 17 years participated. Functional connectivity (FC) was examined through the blood oxygenation level-dependent effect using the left and right amygdala (AMY) as seed regions. Relationships of the time courses within these seeds with voxels across the whole brain were evaluated. Arterial spin labeling was used to assess regional brain activation by examining cerebral blood flow. Increased FC between the left AMY with regions associated with nociceptive processing (eg, thalamus) and right AMY FC changes with areas associated with cognitive functioning (dorsolateral prefrontal cortex) and the default mode network (DMN; parietal lobe) were observed in youth with FAPD after the WL-SPT. These changes were related to changes in pain unpleasantness. Amygdala FC changes post-WL-SPT were also related to changes in pain intensity. Amygdala FC with the DMN in youth with FAPD also differed from healthy controls. Global cerebral blood flow changes were also noted between FAPD and healthy controls, but no significant differences in grey matter were detected either between groups or during the WL-SPT in youth with FAPD. Findings confirm youth with FAPD undergo changes in brain systems that could support the development of biomarkers to enhance understanding of the mechanisms of pain and treatment response.

The Utility of an Anxiety Screening Measure in Youth With Functional Abdominal Pain Disorders and Clinical Characteristics Associated With Presence of Anxiety

OBJECTIVES

Anxiety is common in youth with functional abdominal pain disorders (FAPD) and is related to increased pain-related impairment. However, it is unknown if self-reported anxiety on a clinical screener represents a true anxiety disorder diagnosis in youth with FAPD. Further, little is known about clinical characteristics in youth with FAPD and comorbid anxiety (ANX). Therefore, we evaluated whether the clinical cutoff on the Screen for Anxiety and Related Disorders (SCARED) corresponded with the presence of an anxiety disorder. We predicted a more clinically complex profile (eg, increased pain-related impairment, psychological problems, and family risk factors) in youth with FAPD+ANX compared with youth with FAPD alone.

MATERIALS AND METHODS

Participants completed measures of anxiety, functional disability, pain intensity, pain catastrophizing, and mood, and underwent a semistructured diagnostic interview to assess for psychological disorders. Caregivers completed family characteristics and caregiver distress measures. Analyses of group differences were conducted using χ2 and multivariate tests.

RESULTS

The SCARED appears to be a good proxy for an anxiety disorder in youth with FAPD, particularly for generalized anxiety disorder and social anxiety disorder. Youth with FAPD+ANX reported higher rates of pain-related disability and depressive symptoms compared with those with FAPD alone, but other clinical characteristics and family risk factors were comparable across groups.

DISCUSSION

Findings support the use of the SCARED as a proxy for an anxiety disorder diagnosis in youth with FAPD and suggest youth with FAPD+ANX may have a more complex clinical profile categorized by greater mental health and health-related impairment as compared with youth with FAPD alone.

The Clinical Utility of a Brief Psychological Stress Measure (Patient-Reported Outcomes Measurement Information System) in Youth with Chronic Pain

OBJECTIVE

To preliminarily examine the psychometric properties (i.e., internal consistency reliability, construct validity) and clinical utility of the Patient-Reported Outcomes Measurement Information System (PROMIS) psychological stress experiences scale in a sample of youth with chronic pain.

METHODS

Participant data were gathered from an institutional review board (IRB) approved clinical data registry. One hundred sixty-eight children and adolescents (age: mean = 14.97, SD = 2.78) with chronic pain presenting to a tertiary pain treatment clinic were included in the data set. Internal consistency estimates (i.e., Cronbach's alpha), bivariate correlations, and confirmatory factor analyses were performed to preliminarily examine reliability and validity. Multivariate regression analyses were performed to examine the associations between PROMIS psychological stress and pain-related and psychosocial outcomes.

RESULTS

Confirmatory factor analysis and correlational results indicated that the PROMIS psychological stress experiences scale shows promising reliability and validity in the current sample of youth with chronic pain. Additionally, the results indicated that almost 50% of youth with chronic pain report "high" or "very high" stress (T ≥ 60) and significantly higher rates of stress when compared with national validation samples (P < 0.001). The results also indicated that the PROMIS psychological stress experiences scale was significantly associated with both pain-related and psychosocial outcomes (all P <0.01).

CONCLUSIONS

The PROMIS psychological stress experiences scale shows promising psychometric properties in youth with pediatric pain and may be useful in assessing for psychological impairment. Future research should further examine the use of this brief measure to assess psychological stress in medical clinics as a way to enhance intervention and prevention efforts in these youth.

Cognitive Behavior Therapy Tailored to Anxiety Symptoms Improves Pediatric Functional Abdominal Pain Outcomes: A Randomized Clinical Trial

OBJECTIVES

To evaluate the feasibility of a stepped care model, and establish the effect of a tailored cognitive behavioral therapy, the Aim to Decrease Anxiety and Pain Treatment (ADAPT), compared with standard medical treatment as usual on pain-related outcomes and anxiety.

STUDY DESIGN

Eligible patients between the ages of 9 and 14 years with functional abdominal pain disorders (n = 139) received enhanced usual care during their medical visit to a gastroenterologist. Those that failed to respond to enhanced usual care were randomized to receive either a tailored cognitive behavioral therapy (ADAPT) plus medical treatment as usual, or medical treatment as usual only. ADAPT dose (4 sessions of pain management or 6 sessions of pain and anxiety management) was based on presence of clinically significant anxiety. Outcomes included feasibility, based on recruitment and retention rates. Response to ADAPT plus medical treatment as usual vs medical treatment as usual on pain-related outcomes and anxiety measures was also investigated using a structural equation modeling equivalent of a MANCOVA. Anxiety levels and ADAPT dose as moderators of treatment effects were also explored.

RESULTS

Based on recruitment and retention rates, stepped care was feasible. Enhanced usual care was effective for only 8% of youth. Participants randomized to ADAPT plus medical treatment as usual showed significantly greater improvements in pain-related disability, but not pain levels, and greater improvements in anxiety symptoms compared with those randomized to medical treatment as usual only. Anxiety and ADAPT treatment dose did not moderate the effect of treatment on disability nor pain.

CONCLUSIONS

Tailoring care based on patient need may be optimal for maximizing the use of limited psychotherapeutic resources while enhancing care.

The Co-occurrence of Pediatric Chronic Pain and Anxiety: A Theoretical Review of a Developmentally Informed Shared Vulnerability Model

The development and maintenance of pediatric chronic pain and anxiety are complex, underscoring the need to better understand the interactive forces contributing to their co-occurrence. The shared vulnerability model (SVM) was developed to explain the co-occurrence of chronic pain and posttraumatic stress disorder in adults. Although many core tenets have been well supported by pediatric research, the SVM has yet to be extended to pediatric pain populations. We propose a developmentally informed pediatric SVM for advancing our understanding of the co-occurrence of pediatric chronic pain and anxiety disorders. The proposed SVM postulates that youth at increased risk for the development of chronic pain and/or anxiety share predisposing vulnerabilities, including anxiety sensitivity, and that these shared vulnerabilities give rise to negative emotional responses (child and parent) in the context of stressful events. Consequences of fear and anxiety, including avoidance behavior, further contribute to the development of chronic pain, anxiety, and their co-occurrence. The parental, school, and peer contexts in which these problems develop and are maintained in youth are pertinent to integrate into a SVM, as pediatric chronic pain and anxiety disorders share several social-contextual risk and maintenance factors. We also highlight new areas of inquiry.

The Impact of Posttraumatic Stress Disorder on Clinical Presentation and Psychosocial Treatment Response in Youth with Functional Abdominal Pain Disorders: An Exploratory Study

Youth with functional abdominal pain disorders (FAPDs) may report high rates of trauma and/or posttraumatic stress disorder (PTSD), which could impact both physical and psychosocial functioning, in addition to psychosocial treatment response. The current study aimed to examine the rates of PTSD in a sample of 89 youth with FAPDs and examine the association between PTSD with physical and psychosocial functioning. The impact of PTSD on psychosocial treatment response in a subsample of youth with FAPDs was also explored. Participants were youth with FAPDs (ages 9–14) enrolled in a larger study examining the effect of a short-term pain and anxiety focused cognitive behavioral therapy (CBT) treatment (Aim to Decrease Anxiety and Pain Treatment (ADAPT)) for youth with FAPDs. Youth were administered a semi-structured diagnostic interview by a trained clinician to confirm the presence of psychological diagnoses, including PTSD. Measures of physical and psychosocial functioning were also completed. Results revealed a high rate of PTSD in youth with FAPDs with 12.4% meeting diagnostic criteria for the disorder. PTSD was associated with several indicators of increased psychosocial impairment and one indicator of physical impairment. Exploratory analyses revealed comorbid PTSD may impact response to a brief CBT intervention targeting pain and anxiety, but more rigorous controlled studies are needed.

The Influence of Caregiver Distress and Child Anxiety in Predicting Child Somatization in Youth with Functional Abdominal Pain Disorders

Pediatric functional abdominal pain disorders (FAPD) are associated with adverse outcomes including increased somatization (e.g., heightened physiological sensations that include gastroenterological and non-gastroenterological symptoms) and increased functional disability. Caregiver distress and child anxiety are separately associated with the adverse outcomes of pediatric FAPD. However, the cumulative role of caregiver (i.e., stress, anxiety, and depression) and child psychological functioning (anxiety) in relation to adverse outcomes associated with FAPD, and particularly somatization, is unclear. Thus, the present investigation sought to examine the role of caregiver distress and child anxiety in relation to pain-related functioning (i.e., somatization, pain intensity, functional disability) in youth with FAPD. Data were gathered as part of a larger study examining a psychological treatment for youth with FAPD. Participants (ages 9–14) with FAPD completed measures of child anxiety, pain, and pain-related functioning. Caregivers completed a measure of caregiver distress (e.g., stress, anxiety, depressive symptoms). Pearson correlations revealed significant positive associations between child anxiety and child functional disability. Additionally, caregiver anxiety, child anxiety, and child somatization were all significantly and positively correlated with one another. Therefore, we assessed whether child anxiety may potentially mediate the relationship between caregiver anxiety and child somatization in this cross-sectional study. The indirect association between caregiver anxiety and child somatization via child anxiety was not significant. Future research including longitudinal designs to further understand the relationship between caregiver anxiety, child anxiety, and child pain-related functioning, would enhance understanding of how these potentially modifiable psychological factors may impact adverse outcomes of FAPD.

Best-Evidence for the Rehabilitation of Chronic Pain Part 1: Pediatric Pain

Chronic pain is a prevalent and persistent problem in middle childhood and adolescence. The biopsychosocial model of pain, which accounts for the complex interplay of the biological, psychological, social, and environmental factors that contribute to and maintain pain symptoms and related disability has guided our understanding and treatment of pediatric pain. Consequently, many interventions for chronic pain are within the realm of rehabilitation, based on the premise that behavior has a broad and central role in pain management. These treatments are typically delivered by one or more providers in medicine, nursing, psychology, physical therapy, and/or occupational therapy. Current data suggest that multidisciplinary treatment is important, with intensive interdisciplinary pain rehabilitation (IIPT) being effective at reducing disability for patients with high levels of functional disability. The following review describes the current state of the art of rehabilitation approaches to treat persistent pain in children and adolescents. Several emerging areas of interventions are also highlighted to guide future research and clinical practice.

The role of psychological factors in pediatric functional abdominal pain disorders

BACKGROUND

Pediatric functional abdominal pain disorders (FAPDs) are disorders of brain-gut dysregulation. Psychological factors are known to be related to etiology, maintenance, and exacerbation of pediatric FAPDs. With the evolving literature in the past two decades, a better understanding has emerged of precisely which psychological factors are associated with childhood FAPDs.

PURPOSE

This narrative literature review summarizes the literature of both child and parent psychological factors in pediatric FAPD. Where anxiety and depression were major targets in the older literature, present-day focus is increasingly on pain-specific cognitions and coping strategies including disease threat and catastrophizing. In addition, parental reaction to a child's pain is increasingly recognized as an important moderator of a child's outcomes and has become an area for clinical intervention. Screening for these factors and integrative treatment approaches are recommended in childhood FAPD.

Integrating psychosocial approaches into the management of childhood functional gastrointestinal disorders: a role for social work

FGID is one of the most common pain conditions in children and adversely affects their functioning and quality of life. Recent approaches to the management of paediatric FGID recognise the importance of an integrated biopsychosocial approach. Unfortunately, research findings show that psychosocial factors are often not adequately addressed in the management of FGID in children. We recently conducted a survey of 327 paediatric doctors in Australia to investigate their approaches to managing two of the most common childhood FGID - functional abdominal pain (FAP) and irritable bowel syndrome (IBS). Findings provide important insights into paediatricians' perceptions of the role of psychosocial issues and interventions in these conditions. Implications for social work are discussed.

Psychological Factors and Outcomes in the Surgical Treatment of Pediatric Patients With Median Arcuate Ligament Syndrome

OBJECTIVE

Median arcuate ligament syndrome (MALS) is a frequently overlooked cause of chronic abdominal pain (CAP), and results in many symptoms that mimic other gastrointestinal conditions that result in CAP. A small, but growing body of literature indicates that surgery improves quality of life (QOL) in patients with MALS. The purpose of the current study was to examine the psychological characteristics of pediatric patients with MALS to determine their prevalence and impact on surgical outcomes.

METHODS

Thirty-two pediatric patients completed psychological assessments before surgery, and 6 months postsurgical intervention. Descriptive analyses and t tests were conducted to characterize the sample and compare psychosocial and QOL items. To explore possible associations between coping and ultimate changes in QOL, exploratory multiple regressions were conducted.

RESULTS

Comorbid psychological conditions were common, occurring in about half the sample before and after surgery. Current pain significantly improved, as well as patient and parent-reported QOL constructs (Ps < 0.05). Parent-reported observations of patients using catastrophizing or helpless strategies to cope with pain before surgery was significantly associated with changes in patient and parent-reported QOL following surgery (Ps = 0.04).

CONCLUSIONS

Comorbid psychological conditions are common in pediatric patients with MALS, and are maintained following surgery. While surgery improved pain and QOL, the need for presurgical psychological interventions for MALS is implicated.

Irritability is Common and is Related to Poorer Psychosocial Outcomes in Youth with Functional Abdominal Pain Disorders (FAPD)

Functional abdominal pain disorders (FAPD) are associated with increased emotional problems which, in turn, exacerbate functional impairment. However, irritability, which relates both to internalizing and externalizing problems, has not been specifically examined in these youths. Irritability may be common and adversely impact functioning in pediatric FAPD, particularly for males who are more likely to experience such symptoms. The current study examined the relationship between irritability and psychosocial and pain-related impairment in youth with FAPD. Data were gathered as part of a larger study examining a psychological treatment for youth with FAPD and were compared to previously published data on irritability in healthy controls and in youth with severe emotional dysregulation. For the current study, participants (ages 9–14) with FAPD and caregivers completed measures of child irritability, pain-related and psychosocial functioning, and parent functioning. Pearson correlations revealed significant positive associations between irritability and anxiety, depressive symptoms, pain catastrophizing, and caregiver distress. Results also indicated that parents reported significantly greater irritability in males, but males and females reported similar rates of irritability. Gender moderated the relationship between child-report of irritability and anxiety only. Future research may include tailoring of behavioral intervention approaches for pediatric FAPD to specifically target symptoms of irritability.

School Anxiety in Children and Adolescents with Chronic Pain

Anxiety is highly prevalent in pediatric chronic pain. This comorbidity has been explained by the presence of shared mechanisms underlying the development and maintenance of chronic pain and anxiety. Accumulating evidence demonstrates that school is a significant source of anxiety among youth with chronic pain and that anxiety contributes to school-related functional impairment in this population. This article reviews the cooccurrence of pediatric chronic pain and anxiety, identifies unique sources of heightened school anxiety among youth with chronic pain, and describes current approaches for assessing anxiety in pediatric pain settings. Highlighted by this review is the absence of a comprehensive evidence-based approach for assessing school anxiety in pediatric chronic pain. Given the psychometric limitations inherent to gathering data from a single source, recommendations for advancing measurement methods are provided. Novel approaches may be needed to shed more light on the way in which school anxiety is experienced in pediatric chronic pain.

Abdominal Pain in Children: From the Eternal City to the Examination Room

Abdominal pain is a common presenting symptom in children. The differential diagnosis of abdominal pain is extensive; however, a vast majority of patients ultimately are diagnosed with functional abdominal pain disorders. Functional gastrointestinal disorders are defined using the recently released Rome IV criteria. These are not diagnoses of exclusion. If there are no alarm signs, the diagnosis may be made with a focused evaluation. Treatment of these disorders requires a biopsychosocial approach to the disorder and an individualized and multipronged treatment plan.

Risk Categorization Predicts Disability in Pain-associated Functional Gastrointestinal Disorders After 6 Months

INTRODUCTION

For a large portion of youth, pain-associated functional gastrointestinal disorders (FGIDs) are associated with significant impairment over time. Clinically feasible methods to categorize youth with FGIDs at greatest risk for persistent pain-related impairment have not yet been identified.

METHODS

Measures of functional disability, pain intensity, and anxiety were collected on 99 patients with FGIDs (ages 8-18) during a visit to a pediatric gastroenterology office to assess for the presence of risk. Follow-up data were obtained on a subset of this sample (n = 64) after 6 months, either in person or via mail. The present study examined whether a greater number of risk factors at baseline predicted greater pain-related disability at follow-up.

RESULTS

Patients were divided into 4 groups based on number of risk factors present at the initial assessment: 0 (18.2%), 1 (24.2%), 2 (26.3%), and 3 (31.3%). The presence of 2 or 3 risk factors significantly predicted greater disability at follow-up compared to those with 0 risk factors (R = 0.311) and those with just 1 risk factor (Cohen's d values of -1.07 and -1.44, respectively).

DISCUSSION

A simple approach to risk categorization can identify youth with FGIDs who are most likely to report increased levels of pain-related impairment over time. These findings have important clinical implications that support the utility of a brief screening process during medical care to inform referral for targeted treatment approaches to FGIDs.

Identification and Treatment of Generalized Anxiety Disorder in Children in Primary Care

Youth with anxiety often present to their pediatricians with a chief complaint of physical symptoms without any mention of anxiety or worry. Even in the absence of reported symptoms of anxiety in such presentations, screening for an anxiety disorder as the potential source of the somatic complaints should be pursued. Generalized anxiety disorder (GAD) is a common disorder characterized by excessive anxiety and worry about a number of events coupled with at least one physical symptom. GAD is commonly underdiagnosed and treated. Consequently, many youth undergo extensive medical testing in search of a cause for their somatic symptoms before anxiety is considered. It is important to screen for anxiety early in the process of evaluating somatic complaints. This review highlights the evidence base for identifying and treating GAD in children and provides an update on its epidemiology and etiology. [Pediatr Ann. 2016;45(10):e349-e355.].

Predicting Multiple Facets of School Functioning in Pediatric Chronic Pain: Examining the Direct Impact of Anxiety

OBJECTIVES

The relationships among chronic pain, anxiety, and school functioning are complex, and school functioning is often negatively impacted in youth with chronic pain. The objective of this study was to empirically test a model of associations between constructs predicting school functioning in youth with chronic pain to examine the direct effect of anxiety on school attendance and other indicators of school-related disability.

MATERIALS AND METHODS

Participants included 349 youth and their parents (311 mothers and 162 fathers) who attended a multidisciplinary pain clinic. Youth, mothers, fathers, and clinicians completed assessments of clinical outcomes important to family and clinician perceptions of school functioning; youth, mothers, and fathers completed an assessment of youth anxiety. Structural equation modeling was used to examine interrelations among predictors.

RESULTS

Measurement and structural models for predicting youth school functioning provided a very good fit of the data to the conceptual model. Anxiety was directly related to problems with school attendance and avoidance, concentration, and keeping up with schoolwork.

DISCUSSION

Anxiety was a robust predictor of school functioning across a range of domains. Evaluating anxiety symptoms in pediatric chronic pain will likely facilitate case conceptualization and treatment planning. This study supports a shift in focus from pain to anxiety as the driving force of school impairment in youth with chronic pain.

Anxiety Adversely Impacts Response to Cognitive Behavioral Therapy in Children with Chronic Pain

OBJECTIVE

To evaluate whether clinical anxiety in children presenting to a pediatric pain management center is associated with a poorer treatment response for those who completed pain-focused cognitive behavioral therapy (CBT).

STUDY DESIGN

The total sample consisted of 175 children, 40 of whom completed CBT for chronic pain. The Screen for Child Anxiety Related Emotional Disorders was completed at initial evaluation and outcome measures (average pain intensity and the Functional Disability Inventory) were collected during the initial evaluation and at the end of CBT. Group differences in outcomes were examined following CBT. The role of anxiety in CBT initiation and completion was also explored.

RESULTS

Presence of clinical anxiety was associated with greater initiation and/or completion of pain-focused CBT but also a poorer treatment response. Specifically, the group with subclinical anxiety exhibited a substantial reduction in pain intensity, and the group with clinical anxiety exhibited a more limited response to treatment (F [1, 36] = 13.68 P < .01). A similar effect was observed for Functional Disability Inventory, such that the group with clinical anxiety had a significantly smaller response to treatment (F [1, 38] = 4.33 P < .05). The difference in pain and disability between groups following CBT suggest moderate effects (Cohen d = 0.77 and 0.78, respectively).

CONCLUSIONS

Although youths with clinical anxiety are more likely to start and/or complete pain-focused CBT, anxiety has an adverse impact on CBT treatment response in children with chronic pain. Identification of patients with anxiety and use of tailored behavioral interventions may improve clinical outcomes.

Abdominal pain symptoms are associated with anxiety and depression in young children

AIM

Abdominal pain symptoms and incontinence are common in childhood. The aim of this study was to analyse abdominal pain symptoms and their associations with incontinence and symptoms of anxiety and depression in young children.

METHODS

We examined 1130 children during the school entry check-up (mean age 6.2 years) and 951 participated in the study. Parents completed a questionnaire contained 11 items regarding Rome-III functional gastrointestinal disorders (FGIDs) and incontinence and 14 items from the anxious/depressed scale of the Child Behavior Checklist (CBCL).

RESULTS

Of the 951 children (55.6% boys) we recruited, 30.1% had experienced abdominal pain symptoms in the past two months and 14% had complained of them at least once a week. In addition, 2.6% had irritable bowel syndrome, 11.3% had childhood functional abdominal pain, 2.4% were affected by faecal incontinence, 2.1% were affected by daytime urinary incontinence, and 5.5% were affected by nocturnal enuresis. One in ten (10.6%) had symptoms of anxiety and depression, and these were significantly higher in the children with FGIDs, particularly if they were also incontinent.

CONCLUSION

Nearly a third of the children (30.1%) had abdominal pain symptoms, and FGIDs were associated with significantly higher symptoms of anxiety and depression, especially if children were also incontinent.

Psychometric Properties of the Pain Stages of Change Questionnaire: New Insights on the Measurement of Readiness to Change in Adolescents, Mothers, and Fathers

There is increasing interest in the measurement of "readiness to change," or willingness to engage in a self-management approach to pain coping, as a predictor of treatment response in pediatric pain populations. The primary aim of the present study was to provide cross-validation of the Pain Stages of Change Questionnaire-Adolescent and -Parent versions in a new, independent pediatric chronic pain sample by examining aspects of reliability, validity, and generalizability of the factor structures identified in the initial validation study. Secondary aims were to 1) expand upon previously identified differences between the Pain Stages of Change Questionnaire-Adolescent and -Parent versions and 2) examine previously unreported aspects of father data. Although slight differences emerged, the factor structures identified in the initial validation were largely replicated, suggesting that the psychometric properties of the measure are robust across pediatric outpatient chronic pain samples. Variability between parent and adolescent reports suggests that there may be meaningful differences in the interpretation of each measure and that factors other than readiness to change may influence response patterns. Findings highlight the need for more fine-tuned analyses of the way the construct operates in youth with pediatric pain and their parents.

PERSPECTIVE

Findings provide further validation of the Pain Stages of Change Questionnaire-Adolescent and -Parent versions measures in a new outpatient pediatric chronic pain sample. Previously uninvestigated father data showed good reliability and patterns of findings similar to validated mother reports. Moreover, the study suggests that the adolescent and parent versions may function in meaningfully different ways.

Concordant parent-child reports of anxiety predict impairment in youth with functional abdominal pain

BACKGROUND

Functional abdominal pain (FAP) is associated with significant anxiety and impairment. Prior investigations of child anxiety in youth with FAP are generally limited by small sample sizes, based on child report, and use lengthy diagnostic tools. It is unknown whether a brief anxiety-screening tool is feasible, whether parent and child reports of anxiety are congruent, and whether parent and child agreement of child anxiety corresponds to increased impairment. The purpose of this investigation was to examine anxiety characteristics in youth with FAP using parent and child reports. Parent-child agreement of child anxiety symptoms was examined in relation to pain and disability.

METHODS

One hundred patients with FAP (8-18 years of age) recruited from pediatric gastroenterology clinics completed measures of pain intensity (Numeric Rating Scale) and disability (Functional Disability Inventory). Patients and caregivers both completed a measure of child anxiety characteristics (Screen for Child Anxiety and Related Disorders).

RESULTS

Clinically significant anxiety symptoms were more commonly reported by youth (54%) than their parents (30%). Panic/somatic symptoms, generalized anxiety, and separation anxiety were most commonly endorsed by patients, whereas generalized anxiety, separation anxiety, and school avoidance were most commonly reported by parents. The majority (65%) of parents and children agreed on the presence (26%) or absence (39%) of clinically significant anxiety. Parent-child agreement of clinically significant anxiety was related to increased impairment.

CONCLUSIONS

A brief screening instrument of parent and child reports of anxiety can provide clinically relevant information for comprehensive treatment planning in children with FAP.

Child pain catastrophizing mediates the relation between parent responses to pain and disability in youth with functional abdominal pain

OBJECTIVES

Functional abdominal pain (FAP) in youth is associated with substantial impairment in functioning, and prior research has shown that overprotective parent responses can heighten impairment. Little is known about how a range of parental behaviors (overprotection, minimizing, and/or encouragement) in response to their child's pain interact with child coping characteristics (eg, catastrophizing) to influence functioning in youth with FAP. In this study, it was hypothesized that the relation between parenting factors and child disability would be mediated by children's levels of maladaptive coping (ie, pain catastrophizing).

METHODS

Seventy-five patients with FAP presenting to a pediatric pain clinic and their caregivers participated in the study. Youth completed measures of pain intensity (Numeric Rating Scale), pain catastrophizing (Pain Catastrophizing Scale), and disability (Functional Disability Inventory). Caregivers completed measures of parent pain catastrophizing (Pain Catastrophizing Scale), and parent responses to child pain behaviors (Adult Responses to Child Symptoms: Protection, Minimizing, and Encouragement/Monitoring subscales).

RESULTS

Increased functional disability was significantly related to higher child pain intensity, increased child and parent pain catastrophizing, and higher levels of encouragement/monitoring and protection. Parent minimization was not related to disability. Child pain catastrophizing fully mediated the relation between parent encouragement/monitoring and disability and partially mediated the relation between parent protectiveness and disability.

CONCLUSIONS

The impact of parenting behaviors in response to FAP on child disability is determined, in part, by the child's coping style. Findings highlight a more nuanced understanding of the parent-child interaction in determining pain-related disability levels, which should be taken into consideration in assessing and treating youth with FAP.

Presentation and management of chronic pain

Chronic pain is an important clinical problem affecting significant numbers of children and their families. The severity and impact of chronic pain on everyday function is shaped by the complex interaction of biological, psychological and social factors that determine the experience of pain for each individual, rather than a straightforward reflection of the severity of disease or extent of tissue damage. In this article we present the research findings that strongly support a biopsychosocial concept of chronic pain, describe the current best evidence for management strategies and suggest a common general pathway for all types of chronic pain. The principles of management of some of the most important or frequently encountered chronic pain problems in paediatric practice; neuropathic pain, complex regional pain syndrome (CRPS), musculoskeletal pain, abdominal pain and headache are also described.
