Psychological comorbidity and stress reactivity in children and adolescents with recurrent abdominal pain and anxiety disorders

Mental health markers and protective factors in students with symptoms of physical pain across WEIRD and non-WEIRD samples - a network analysis

BACKGROUND

Studies conducted in Western societies have identified variables associated with chronic pain, but few have done so across cultures. Our study aimed to clarify the relationship between specific mental health markers (i.e., depression, anxiety, posttraumatic stress disorder [PTSD], perceived stress) as well as specific protective factors (i.e., social support and self-efficacy) related to physical pain among university students across non-WEIRD and WEIRD samples.

METHOD

A total of 188 university students (131 women and 57 men) were included in the study. We used network analysis to ascertain mental health markers especially central to the experience of physical pain.

RESULTS

No statistically significant difference was found between mental health markers (i.e., depression, anxiety, perceived stress, and PTSD) and protective factors (i.e., social support and self-efficacy) associated with physical pain symptoms for Swiss students versus Indian students (M = 0.325, p = .11). In addition, networks for Swiss versus Indian students did not differ in global strength (S = 0.29, p = .803). Anxiety was the most central mental health marker, and social support was the most important protective factor related to physical pain in both countries. However, for Swiss students, perceived stress, and for Indian students, PTSD symptoms were central mental health markers related to physical pain.

CONCLUSION

Our results identify factors that may serve as important treatment targets for pain interventions among students of both countries before it becomes chronic.

Topical Review: Getting into the head of youth with chronic pain: how theory of mind deficits may relate to the development and maintenance of pediatric pain

OBJECTIVE

Theory of mind (ToM) is the ability to understand the thoughts, feelings, and mental states of others and is critical for effective social and psychological functioning. ToM deficits have been associated with various psychological disorders and identified in adult pain populations. For youth with chronic pain, ToM deficits may underlie the biological, psychological, and social factors that contribute to their experience of pain, but this remains poorly understood.

METHODS

This topical review explored the extant literature in the areas of ToM and chronic pain, particularly for pediatric populations, with respect to biological, psychological, and social elements of the biopsychosocial model of pain.

RESULTS

ToM deficits may be present alongside previously identified biological, psychological, and social correlates of pediatric pain, as a vulnerability, mechanism, and/or consequence. Biologically, ToM deficits may relate to cortisol abnormalities and neurobiological substrates of pain processing. Psychologically, ToM deficits may stem from pain-focused cognitions, thus impacting relationships and fueling impairment. Socially, chronic pain may preclude normative development of ToM abilities through social withdrawal, thereby exacerbating the experience of pain.

CONCLUSION

Taken together, ToM deficits may be associated with increased risk for the development and/or maintenance of pediatric chronic pain, and pediatric chronic pain may similarly confer risk for ToM deficits. Future research should investigate the nature of ToM abilities in youth with chronic pain to test these hypotheses and ultimately inform ToM-focused and pain-based interventions, as this ability has been demonstrated to be modifiable.

Study protocol for a pilot clinical trial to understand neural mechanisms of response to a psychological treatment for pain and anxiety in pediatric functional abdominal pain disorders (FAPD)

BACKGROUND

Functional abdominal pain disorders (FAPD) are the most common chronic pain conditions of childhood and are made worse by co-occurring anxiety. Our research team found that the Aim to Decrease Pain and Anxiety Treatment (ADAPT), a six-session coping skills program using cognitive behavioral therapy strategies, was effective in improving pain-related symptoms and anxiety symptoms compared to standard care. In follow-up, this current randomized clinical trial (RCT) aims to test potential neural mechanisms underlying the effect of ADAPT. Specifically, this two-arm RCT will explore changes in amygdalar functional connectivity (primary outcome) following the ADAPT protocol during the water loading symptom provocation task (WL-SPT). Secondary (e.g., changes in regional cerebral blood flow via pulsed arterial spin labeling MRI) and exploratory (e.g., the association between the changes in functional connectivity and clinical symptoms) outcomes will also be investigated.

METHODS

We will include patients ages 11 to 16 years presenting to outpatient pediatric gastroenterology care at a midwestern children's hospital with a diagnosis of FAPD plus evidence of clinical anxiety based on a validated screening tool (the Generalized Anxiety Disorder-7 [GAD-7] measure). Eligible participants will undergo baseline neuroimaging involving the WL-SPT, and assessment of self-reported pain, anxiety, and additional symptoms, prior to being randomized to a six-week remotely delivered ADAPT program plus standard medical care or standard medical care alone (waitlist). Thereafter, subjects will complete a post assessment neuroimaging visit similar in nature to their first visit.

CONCLUSIONS

This small scale RCT aims to increase understanding of potential neural mechanisms of response to ADAPT.

Higher self-perceived stress reactivity is associated with increased chronic pain risk

Self-perceived stress reactivity—how a person cognitively and emotionally responds to a stressor—is longitudinally associated with increased odds for the development of chronic pain.

Introduction:

Experiencing stress can contribute to unfavorable pain experiences, but outcomes vary across individuals. Evidence suggests that a person's specific reactivity to stressful events may influence pain responses. Previous studies measuring physiological stress reactivity have found associations with pain both clinically and in the laboratory. However, the time and cost required for testing physiological stress reactivity may limit clinical application.

Objective:

Self-reported perception of one's own stress reactivity has been shown to correlate with physiological stress reactivity in relation to health outcomes and may represent a valuable tool in clinical pain assessment.

Methods:

Using data from the Midlife in the US survey, we selected participants who did not have chronic pain at baseline (n = 1512) and who had data at follow-up 9 years later. Stress reactivity was assessed using a subscale of the Multidimensional Personality Questionnaire. We conducted a binary logistic regression to determine the odds of developing chronic pain, controlling for demographics and other health-related variables.

Results:

Results indicate that higher reported stress reactivity at baseline increased the odds of developing chronic pain at follow-up (odds ratio (OR) = 1.085, 95% confidence interval (CI) (1.021, 1.153), P = 0.008), with the only other significant predictor being the number of chronic conditions (OR = 1.118, 95% CI (1.045, 1.197), P = 0.001).

Conclusion:

Findings provide evidence for the predictive criterion validity of self-reported stress reactivity in the context of chronic pain risk. More generally, with increased need for virtual assessment and care, self-reported stress reactivity may be a useful, time-efficient, and cost-efficient tool for predicting pain outcomes in research and clinical contexts.

Clinical Presentations of Teenage Outpatients Encountered by General Internists in Japanese Hospitals: A Cross-Sectional Study

Introduction General internists in Japanese hospitals sometimes consult on adolescents. Our university hospital encounters more adolescents with mental health complaints than other city hospitals. Consequently, based on our experience, we hypothesized that psychiatric disorders are significantly more common among teenagers who visit general internists. Therefore, we retrospectively analyzed the clinical profiles of teenage outpatients who visited general internists at three hospitals to test this hypothesis. Methods This study included 342 patients aged 13-19 years who visited the Departments of General Internal Medicine at Toyama University Hospital, Nanto Municipal Hospital, and Kamicichi General Hospital between January 2019 and December 2021. Data on age, sex, chief complaint, the period from onset to visit, referral status, and final diagnosis were collected from medical records. We also identified the final diagnoses of 1,375 outpatients from the university hospital during the same period, stratifying them by age. Multiple comparison analyses, Chi-squared tests, and residual analyses were performed to analyze the data. Results The number of psychiatric teen patients was significantly higher in the university hospital group than in the other city hospital groups (p<0.01). The incidence of psychiatric disorders, such as stress-related mental disorders, including adjustment and eating disorders (p<0.001), was also significantly higher in the teenage group (13-19 years) than in other age groups. Most psychiatric disorders lead to complaints of physical symptoms. Conclusions The potential onset of clinical episodes during consultations with teenage patients can make treating this age group more challenging; thus, they may require care at university hospitals. Furthermore, Japanese general internists in university hospitals encounter patients in their late teens with physical signs more often than in other hospitals. This trend may be unique to general medicine departments ("Sogo-Shinryo") in Japanese university hospitals. However, if general internists act under primary care principles, they can adequately assist adolescent patients.

Combining Dance/Movement Therapy with Cognitive Behavioral Therapy in Treatment of Children with Anxiety Disorders: Factors Explaining Therapists' Attitudes

Anxiety disorders (ADs) are among the most common psychiatric disorders and they may appear as early on as in childhood. The current study addressed the combination of two treatments approaches for ADs: Dance/movement therapy (DMT) and cognitive behavioral therapy (CBT), focusing on factors that explain the therapists' attitudes towards actually combining the two therapies. The study utilized a quantitative design, with a perceptions survey administered via an online questionnaire. Ninety-nine therapists participated in the study (DMT-only n = 35, CBT-only n = 42, and DMT + CBT, n = 22). Following preliminary analysis (comparison between the groups, correlations and factor analysis), the structural equation model (SEM, confirmatory factor analysis) revealed a good fit between the theoretical model and the empirical data. First, it was found that the reported actual use of the combined approaches (DMT + CBT) in treatment of children with ADs, was significantly explained by therapists who had experience practicing DMT but not CBT perceiving this combination as efficient. Second, the therapists' use of the combined therapy (DMT + CBT) approaches was not related to their sense of efficacy as therapists of children with ADs. The model represents concordance between the components of the therapists' attitudes: Affective—belief that it is efficient, cognitive—perception of it as effective, and behavioral—their actual use.

Child and adolescent psychiatry staff's knowledge on pain management

OBJECTIVE

To assess the level of child and adolescent psychiatric staff's knowledge regarding pain management, to determine group differences between the medically more educated (physicians, nurses) and the less educated (psychologists, educators, special therapists) and to investigate the influence of gender, age, or professional experience as well as staff's own pain experiences.

METHODS

A total of 193 staff members from different professional backgrounds from three independent child and adolescent psychiatry clinics in Northern Germany were tested using the German version of the Pediatric Nurses' Knowledge and Attitudes Survey Regarding Pain Shriner's revision (PNKAS-Sr).

RESULTS

In total, the staff scored correctly 66% of the inventory questions. There was no difference between medically more educated and less educated staff members regarding the knowledge of pain management. The main factors influencing PNKAS score were age, profession, and pain education training.

CONCLUSIONS

Although chronic pain is not one of the main aspects of continuing education in child and adolescent psychiatry, the resulting level of knowledge was comparable to results of similar surveys with paediatric staffs. Nevertheless, further education is needed to enhance knowledge and understanding of children's pain in child psychiatry staff in order to professionally treat patients with chronic somatic and mental illnesses.

Child-Focused Cognitive Behavioral Therapy for Pediatric Abdominal Pain Disorders Reduces Caregiver Anxiety in Randomized Clinical Trial

Pediatric functional abdominal pain disorders (FAPD) are associated with elevated anxiety in youth and their caregivers, both contributing to an adverse impact on functioning in youth with FAPD. While a CBT approach (ie, Aim to Decrease Anxiety and Pain Treatment [ADAPT]) is known to improve health outcomes for youth, it is unknown if child-focused treatment improves caregiver anxiety. This secondary analysis of a larger randomized clinical trial examined if child-focused CBT (ADAPT) for pain and anxiety also impacts caregiver anxiety and explored the relation between caregiver anxiety and child symptoms (ie, pain, disability, anxiety) after treatment. A total of 79 caregiver-child dyads were randomized to ADAPT plus treatment as usual (TAU) or TAU only. Caregiver anxiety and child outcomes (pain, disability, anxiety) were assessed at baseline and approximately 8 weeks later. Caregivers of children who completed ADAPT+TAU demonstrated lower anxiety compared to those who only received TAU. Moreover, regardless of treatment assignment, caregivers with greater anxiety had children who reported more pain and anxiety, but not functional disability at post-assessment. Results suggest a brief, child-focused intervention targeting pain and anxiety may also improve caregiver anxiety. As such, suggestions to improve future treatments are offered. PERSPECTIVE: Caregiver anxiety symptoms diminished after their child with functional abdominal pain completed a course of child-focused CBT targeting pain and anxiety. Further, caregiver anxiety was related to child-reported symptoms (pain and anxiety) after treatment. Therefore, improved caregiver mental health via a child-focused CBT may also improve pediatric outcomes.

Functional abdominal pain symptom severity: Associations between cognition and emotion in a pediatric sample

Functional abdominal pain (FAP) is a common physical complaint in children and adolescents. Prior research has documented associations between FAP symptoms and mood, especially internalizing behaviors. Limited research is available examining the association between symptom burden and cognitive function in this pediatric population. This study explored associations between FAP symptoms, internalizing behaviors, and cognitive and school function in children and adolescents. Twenty-seven participants (mean age = 12.6 years, range 8.8-16.5; 33% male) diagnosed with FAP completed assessments of cognitive, emotional, and behavioral function, as well as FAP symptom severity. Mean performances on cognitive tests were within age-expected ranges. Within this context, however, higher overall burden of FAP symptoms was associated with slower processing speed, more self-reported metacognitive problems and internalizing behaviors, and more school absences. Cognitive function was systematically associated with internalizing behaviors but not physical symptoms. Overall, findings revealed that FAP may be associated with cognitive inefficiencies in addition to internalizing problems. Cognitive symptoms may be linked to internalizing behaviors associated with FAP.

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.

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.

Associations between autonomic nervous system activity and risk-taking and internalizing behavior in young adolescents

Dysregulated autonomic nervous system (ANS) activity has been associated with adolescent risk‐taking and internalizing behavior, but previous results in community samples have been mixed. We investigated whether ANS activity was associated with higher risk‐taking and internalizing behavior in young adolescents (age 11/12; n = 875), and whether adolescents' gender, parents' parenting style or a combination of both moderated these associations. Adolescents and their parents were recruited as part of the population‐based, longitudinal Amsterdam Born Children and their Development (ABCD) study. Risk‐taking behavior was assessed with the Balloon Analogue Risk Task and the personality characteristics sensation seeking and impulsivity, measured with the Substance Use Risk Profile Scale (SURPS). Internalizing behavior was assessed via the SURPS subscales anxiety sensitivity and hopelessness. Authoritative (AUTH‐SW) and authoritarian (AUTH‐S) parenting styles were measured with the Parenting Styles and Dimensions Questionnaire. Resting ANS activity was assessed via heart rate and respiratory sinus arrhythmia (RSA). Hierarchical, multivariable regression analyses showed higher RSA, but not heart rate, being associated with higher risk‐taking behavior and sensation seeking. The associations between ANS activity and risk‐taking variables were not significantly moderated by gender, parenting, or interactions between gender and parenting. Our findings suggest that RSA activity may be a relevant factor in mild to moderate risk‐taking behavior in adolescents from the general population, regardless of their gender or the type of parenting they experience.

Dysregulated autonomic nervous system activity has been associated with adolescent risk‐taking and internalizing behavior, but previous results in community samples have been mixed. Our findings suggest that in adolescents from the general population, respiratory sinus arrhythmia activity may be a relevant factor in mild to moderate risk‐taking behavior but not in internalizing behavior, regardless of adolescents' gender or the type of parenting they experience.

An elevated anxiety level among prepubertal autistic boys with non-treatment-seeking functional gastrointestinal disorders: A case-control study

Children with autism commonly suffer from comorbid functional gastrointestinal disorders (FGID) and anxiety. The raised prevalence of both conditions in autism suggests complex reciprocal relationships, which are seldom explored in non-treatment-seeking FGID. The relationships between subtypes of FGID and anxiety are also unclear. This study recruited boys with autism and age-matched typically developing (TD) boys, aged 4-11 years, who were not actively seeking help for gastrointestinal problems. Their parents completed the Rome IV Diagnostic Questionnaires for Pediatric FGID. Four groups of children with and without autism/FGID were identified and compared on their anxiety level using the Spence children's anxiety scale. In 69 boys with autism and 69 age-matched TD boys, FGID were identified in 22 and 16 boys, respectively. ANCOVA demonstrated a significant interaction effect of autism and FGID on anxiety (F[1, 129] = 5.43, p = 0.021), while conditional logistic regression identified an interaction effect of autism and anxiety on the odds of FGID (OR 1.038, 95% CI 1.002-1.075, p = 0.038). Explorative post hoc analysis showed higher anxiety in functional nausea and vomiting disorder (p = 0.033) and functional abdominal pain disorder (p = 0.029) among boys with autism than TD boys with the same respective subtypes of FGID. In summary, among prepubertal boys with autism, the presence of FGID that are non-treatment-seeking in nature, has a significantly stronger association with higher levels of anxiety than TD boys. The strength of association may be more prominent in subtypes of FGID. Possible pathomechanisms including the underlying microbiota spectra and inflammatory paths should be explored in future studies. LAY SUMMARY: Anxiety and gastrointestinal problems are common symptoms in autism. Given that gut health could be linked to emotions, their association in young boys with autism was studied. The presence of nausea vomiting, or abdominal pain were associated with raised anxiety among boys with autism, yet this was not observed in typically developing boys. This suggests that anxiety among autistic children could be partly explained by the presence of FGID.

Systematic Review of Autonomic Nervous System Functioning in Pediatric Chronic Pain

OBJECTIVES

Chronic pain is a common and debilitating health problem that impacts up to one third of children and adolescents. The pathophysiological mechanisms of chronic pain are complex, but considerable research links dysfunction of the autonomic nervous system (ANS) and chronic pain in adults. No review of ANS functioning has been conducted in pediatric chronic pain. We systematically reviewed studies examining ANS activity among youth with primary chronic pain conditions.

METHODS

A systematic search of PsycINFO, PubMed, and CINAHL was conducted using specific search terms. Articles were included if studies measured heart rate, blood pressure, heart rate variability, galvanic skin responses, or pupillometry among children or adolescents with a chronic pain condition. Studies examining these factors in the context of a specific disease-related pain condition were excluded.

RESULTS

Of the 1304 articles screened, 15 studies met the criteria for inclusion in this review. All included studies were cross-sectional and primarily included youth with abdominal pain. Results revealed preliminary evidence of reduced parasympathetic activity among youth with pain as measured by heart rate variability. However, results were mixed across ANS indices. Measurement and procedural differences, in addition to a lack of control groups in some studies, limit the interpretability of the reviewed findings.

DISCUSSION

Additional studies with larger and more diverse samples of youth with various chronic primary pain conditions are needed to delineate possible relationships among ANS functioning and the development and maintenance of chronic pain in children and adolescents. Clinical implications and avenues for future research are discussed.

Allostatic load: Developmental and conceptual considerations in a multi-system physiological indicator of chronic stress exposure

Developmental researchers studying how stress affects health have often focused on specific, individual, physiological parameters such as cortisol. Yet, recent theories of stress biology emphasize that the stress response is multi-faceted and engages distinct yet interconnected physiological systems, including metabolic, immune, and cardiovascular systems that respond to one another. Moreover, advocates of a systems approach also argue that the confluence of changes across several physiological systems presents a health risk, even when one indicator alone is not predictive of health outcomes. Allostatic load is one potential multi-system indicator of stress, capturing the cumulative, physiological burden of chronic stress exposure on the body. At the same time, studying allostatic load during early development raises several issues, including how allostatic load is operationalized, the clinical importance of commonly used biomarkers during distinct periods of development, and the fundamental role of timing. In this review paper, we discuss the potential of allostatic load in the context of studies of stress in developmental science, review developmental studies that have assessed allostatic load, and articulate critical conceptual questions regarding the study of allostatic load during the childhood years.

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.

Anxiety and Mood Disorders Impacting Physician Opioid Prescribing in the Pediatric Hospital Setting

This research examined whether pediatric inpatients without an anxiety/mood disorder are more likely to receive opioids in response to pain compared to patients diagnosed with a mental health condition. Research questions were tested using cross-sectional inpatient electronic medical record data. Propensity score matching was used to match patients with a disorder with patients without the disorder (anxiety analyses: N = 2892; mood analyses: N = 1042). Although patients with anxiety and mood disorders experienced greater pain, physicians were less likely to order opioids for these patients. Analyses also disclosed an interaction of anxiety with pain-the pain-opioid relation was stronger for patients without an anxiety disorder than for patients with an anxiety diagnosis. Instead, physicians were more likely to place non-opioid analgesic orders to manage the pain of patients with anxiety disorders. Findings imply that pain management decisions might be influenced by patient's mental health.

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.

Preclinical Considerations about Affective Disorders and Pain: A Broadly Intertwined, yet Often Under-Explored, Relationship Having Major Clinical Implications

Background: Pain, a distinctive undesirable experience, encompasses several different and fluctuating presentations across varying mood disorders. Therefore, the present narrative review aimed to shed further light on the matter, accounting for both experimental animal models and clinical observations about major depressive disorder (MDD) pathology. Method: Major databases were inquired from inception until April 2016 for records about MDD and pain. Results: Pain and MDD are tightly associated with each other in a bi-directional fashion. Several cross-sectional and retrospective studies indicated a high presence of pain in the context of mood disorders, including MDD (up to 65%), but also increased prevalence rates in the case of mood disorders documented among people with a primary diagnosis of either psychological or somatic pain (prevalence rates exceeding 45%). The clinical implications of these observations suggest the need to account for mood and pain manifestations as a whole rather than distinct entities in order to deliver more effective interventions. Limitations: Narrative review, lack of systematic control groups (e.g., people with the primary diagnosis at review, but not the associated comorbidity as a study) to allow reliable comparisons. Prevalence rates and clinical features associated with pain varied across different studies as corresponding operational definitions did. Conclusions: Pain may have a detrimental effect on the course of mood disorders-the opposite holds. Promoting a timely recognition and management of such an often neglected comorbidity would therefore represent a primary goal toward the delivery of effective, multi-disciplinary care.

A review of the intriguing interaction between testosterone and neurocognitive development in males with 47,XXY

PURPOSE OF REVIEW

Although 47,XXY (Klinefelter syndrome) was first discovered more than 50 years ago, there have been limited comprehensive studies on this disorder. The present review explains the study of neurodevelopmental dysfunction and the impact of testosterone replacement at specific junctions in the life of males with 47,XXY. The intricate relationship between testosterone, neurodevelopment, health, and well being warrants an in-depth investigation in order to achieve optimal outcomes.

RECENT FINDINGS

Current literature suggests that the implementation of biological treatment has a positive impact on numerous areas of neurodevelopment. Further research is needed to determine ideal dosage, timing, and frequency of biological treatment for efficacy and safety of the child with 47,XXY.

SUMMARY

As noninvasive prenatal screening has detected increasing numbers of fetuses with 47,XXY, parents may benefit from both prenatal and postnatal counseling, including the latest innovative biological treatment, that may further optimize the child's outcome, especially when coupled with targeted early intervention services.

Inflammation, depression, and anxiety disorder: A population-based study examining the association between Interleukin-6 and the experiencing of depressive and anxiety symptoms

The uncovering of a positive association between inflammatory cytokine levels - Interkleukin-6 (IL-6) in particular - and the experiencing of depressive and anxiety symptoms is one of the most promising and enthusiastically-discussed finding in recent years. Despite considerable ambiguity in the directionality and underpinnings of this association, anti-inflammatory drugs are already being tested on mental health patients who present no physical symptoms of inflammation, risking potential adverse side effects. Researchers have thus urgently called for more rigorous empirical elucidations of this association. Based on a large, longitudinal, nationally representative sample of middle-aged adults in the United States (N = 1255), IL-6 was observed to be significantly associated with one's present experiencing of depressive and anxiety symptoms. However, IL-6 was predictive of only prospective depressive (not anxiety) symptoms measured six years later, and only when baseline number of symptoms was not accounted for. Further, evidence for IL-6's postulated role as being either a biological cause itself (augmenting HPA stress reactivity) or a biological consequence of a psychological cause (psychological stress) for depression and anxiety was not found. These findings underscore the imperativeness of more rigorous studies to be conducted in this area, and caution practitioners against the premature consideration of IL-6 levels in clinical practice.

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.

Low FODMAP diet in children and adolescents with functional bowel disorder: A clinical case note review

Background and Aims

Functional bowel disorders (FBD), such as irritable bowel syndrome (IBS), are increasingly more common in children and affect up to 20% of children. The etiology is multifactorial with no clear organic cause. Symptoms are recurrent and are associated with a reduced quality of life, school absences, and psychological challenges. Treatment options are variable. FODMAPs are short‐chained carbohydrates, poorly absorbed by the gastrointestinal tract due to their increased osmotic activity and excess gas production from the bacterial fermentation process. There is a paucity of data examining dietary interventions that restrict carbohydrates in children with IBS. The aim of this study was to examine the use of the low FODMAP diet (LFD) in children with an FBD.

Methods

A retrospective clinical case note review of children with an FBD managed with an LFD was undertaken. Anthropometry and clinical data were collected by a pediatric gastroenterology dietitian. An IBS satisfaction survey was used to assess diet outcomes. Statistical analyses were completed using Excel.

Results

Of the 29 children included in this study, complete resolution of gastrointestinal symptoms was observed for 11 of 12 (92%) of those with bloating, 13 of 15 (87%) of those with diarrhea, and 17 of 22 (77%) of those with abdominal pain. Twenty‐three (79%) participants reported an improvement of symptoms. Fructans were the most common symptom‐causing carbohydrate.

Conclusion

The LFD is a useful dietary treatment strategy for children with FBD. This study adds to the small body of evidence supporting FODMAP dietary interventions in children with FBD. Further prospective studies are required.

An inactive control of the 'Trier Social Stress Test' for Youth 10-17 years: Neuroendocrine, cardiac, and subjective responses

The Trier Social Stress Test for children (TSST-C) adapted from TSST is one of the most commonly used laboratory paradigms for investigating the effects of stress on cognitive, affective and physiological responses in children and adolescents. Considering that laboratory procedures generate a significant amount of stress to children and adolescents, even in the absence of a stress paradigm, it is important to validate TSST-C against an inactive control condition in which the stress components were absent. Using a randomized design, we tested an inactive control condition, which replaced the TSST-C with a benign video clip (nature scenes viewed while standing), thus removing the stress associated components of the TSST-C. Eighty-eight youth between the ages of 10 and 17 years were randomly assigned to complete the TSST-C or the Inactive Control (IC). Subjective anxiety rating, salivary cortisol, systolic and diastolic blood pressure, and heart rate were collected at eight time points. Subjects in the Inactive Control condition showed no significant changes in blood pressure and heart rate, and decreased anxiety rating and salivary cortisol level throughout the study. Subjects in the stress condition (TSST-C) showed increased anxiety ratings, salivary cortisol, systolic and diastolic blood pressure, and heart rate immediately following TSST-C stress induction. Our findings validated that the TSST-C induced a systemic stress response, and that the Inactive Control can be a promising standardized control condition for the TSST-C and a tool for future psychobiological research. Our results also showed that anxiety reactivity decreased with age while HR reactivity increased with age. Cortisol reactivity did not fall in a linear relationship with age but rather via a quadratic curve, suggesting the mid-age adolescents had the highest cortisol responses to stress compared to their younger and older peers, potentially due to a dual factor of pubertal development and self-control and emotion regulation capacity.

Focus on the use of antidepressants to treat pediatric functional abdominal pain: current perspectives

Chronic abdominal pain is frequently encountered in pediatric practice. A large proportion of cases meet Rome criteria for abdominal pain-functional gastrointestinal disorders (AP-FGIDs). These disorders are costly and, in some cases, lead to impairment of daily functioning and overall quality of life. Pathophysiologic mechanisms include early stressful events, visceral hypersensitivity, dysmotility, changes in intestinal microbiota, and altered central nervous system processing. They are considered disorders of the brain-gut interaction. The diagnosis is made on clinical grounds using symptom-based criteria (Rome criteria). Anxiety and depressive symptoms are more prevalent in patients with AP-FGIDs. Therefore, attention has been directed to the use of neuromodulators as potential interventions for AP-FGIDs. Antidepressants are one type of neuromodulators, and one of the most studied drugs for the management of AP-FGIDs in adult and pediatric population. Data available in pediatric population have significant limitations including nonuniform methodology with different study designs and primary endpoints. Evidence of the efficacy of antidepressants in the management of pediatric AP-FGIDs is not consistent. There is an urgent need for well-designed randomized clinical trials using age-appropriate validated outcome measures. Careful consideration must be given to adverse effects, particularly increased suicidal ideation.

Somatic symptoms in adolescence as a predictor of severe mental illness in adulthood: a long-term community-based follow-up study

BACKGROUND

Somatic symptoms are common and costly for society and correlate with suffering and low functioning. Nevertheless, little is known about the long-term implications of somatic symptoms. The objective of this study was to assess if somatic symptoms in adolescents with depression and in their matched controls predict severe mental illness in adulthood by investigating the use of hospital-based care consequent to different mental disorders.

METHODS

The entire school population of 16-17-year-olds in the city of Uppsala, Sweden, was screened for depression in 1991-1993 (n = 2300). Adolescents with positive screenings (n = 307) and matched non-depressed controls (n = 302) participated in a semi-structured diagnostic interview for mental disorders. In addition, 21 different self-rated somatic symptoms were assessed. The adolescents with depression and the matched non-depressed controls were engaged in follow-up through the National Patient Register 17-19 years after the baseline study (n = 375). The outcome measures covered hospital-based mental health care for different mental disorders according to ICD-10 criteria between the participants' ages of 18 and 35 years.

RESULTS

Somatic symptoms were associated with an increased risk of later hospital-based mental health care in general in a dose-response relationship when adjusting for sex, adolescent depression, and adolescent anxiety (1 symptom: OR = 1.63, CI 0.55-4.85; 2-4 symptoms: OR = 2.77, 95% CI 1.04-7.39; ≥ 5 symptoms: OR = 5.75, 95% CI 1.98-16.72). With regards to specific diagnoses, somatic symptoms predicted hospital-based care for mood disorders when adjusting for sex, adolescent depression, and adolescent anxiety (p < 0.05). In adolescents with depression, somatic symptoms predicted later hospital-based mental health care in a dose-response relationship (p < 0.01). In adolescents without depression, reporting at least one somatic symptom predicted later hospital-based mental health care (p < 0.05).

CONCLUSIONS

Somatic symptoms in adolescence predicted severe adult mental illness as measured by hospital-based care also when controlled for important confounders. The results suggest that adolescents with somatic symptoms need early treatment and extended follow-up to treat these specific symptoms, regardless of co-occurring depression and anxiety.

Integrating Psychological Screening Into Medical Care for Youth With Abdominal Pain

BACKGROUND

Pediatric functional abdominal pain disorders are common, costly, and disabling. Clinical anxiety is highly prevalent and is associated with increased pain and functional disability. Thus, a psychological screening process is recommended but is infrequently used in current practice.

METHODS

A screening process for patient-reported anxiety (Screen for Child Anxiety and Related Disorders), functional disability (Functional Disability Inventory), and pain levels was implemented in a large gastroenterology division within a major medical center. Quality improvement methods and traditional analytic approaches were used to test the feasibility and outcomes of routine screening in patients ages 8 to 18 with abdominal pain.

RESULTS

Screening rates increased from <1% to >80%. A total of 1291 patients who reported having abdominal pain completed the screening during the first 6 months. Clinically significant anxiety (43.1%), at least moderate disability (45%), and elevated pain (61.5%) were common in children with abdominal pain. The presence of clinically significant anxiety corresponded with higher pain and pain-related disability. Twenty-one percent of youth had clinical elevations in all 3 areas. In such instances, medical providers received an automated prompt to tailor care, including to consider a psychological referral. After the project implementation, psychological referral rates increased from 8.3 per 1000 patients to 15.2 per 1000 patients.

CONCLUSIONS

Systematic screening for anxiety, pain, and pain-related disability as a routine part of medical care can be reliably implemented with clinically meaningful results. Future directions include examining the role of anxiety over the long-term and reducing clinician burden.

Students with Anxiety: Implications for Professional School Counselors

Anxiety is one of the most pervasive mental health concerns affecting students, yet a significant number of students with anxiety disorders remain underserved. If left untreated, anxiety can hinder students’ personal/social, academic, and career development. The purpose of this article is to provide professional school counselors with helpful information about the etiology of anxiety disorders and brief, evidence-based prevention and intervention options. The authors discuss specific recommendations for the identification, assessment, and treatment of anxiety that fit within the unique school environment.

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.

Characteristics of HIV-infected adolescents enrolled in a disclosure intervention trial in western Kenya

Knowledge of one's own HIV status is essential for long-term disease management, but there are few data on how disclosure of HIV status to infected children and adolescents in sub-Saharan Africa is associated with clinical and psychosocial health outcomes. We conducted a detailed baseline assessment of the disclosure status, medication adherence, HIV stigma, depression, emotional and behavioral difficulties, and quality of life among a cohort of Kenyan children enrolled in an intervention study to promote disclosure of HIV status. Among 285 caregiver-child dyads enrolled in the study, children's mean age was 12.3 years. Caregivers were more likely to report that the child knew his/her diagnosis (41%) compared to self-reported disclosure by children (31%). Caregivers of disclosed children reported significantly more positive views about disclosure compared to caregivers of non-disclosed children, who expressed fears of disclosure related to the child being too young to understand (75%), potential psychological trauma for the child (64%), and stigma and discrimination if the child told others (56%). Overall, the vast majority of children scored within normal ranges on screenings for behavioral and emotional difficulties, depression, and quality of life, and did not differ by whether or not the child knew his/her HIV status. A number of factors were associated with a child's knowledge of his/her HIV diagnosis in multivariate regression, including older age (OR 1.8, 95% CI 1.5-2.1), better WHO disease stage (OR 2.5, 95% CI 1.4-4.4), and fewer reported caregiver-level adherence barriers (OR 1.9, 95% CI 1.1-3.4). While a minority of children in this cohort knew their HIV status and caregivers reported significant barriers to disclosure including fears about negative emotional impacts, we found that disclosure was not associated with worse psychosocial outcomes.

Development of the Aim to Decrease Anxiety and Pain Treatment for Pediatric Functional Abdominal Pain Disorders

OBJECTIVES

To evaluate the feasibility and acceptability of the Aim to Decrease Anxiety and Pain Treatment (ADAPT), a brief, on-line and in-person behavioral intervention targeting pain and anxiety in youth with functional abdominal pain disorders (FAPDs).

METHODS

Patients were recruited from several outpatient pediatric gastroenterology clinics. Nine participants (ages 9-13) completed the full protocol. Thematic analysis of detailed qualitative feedback was obtained via semistructured patient and caregiver interviews after treatment was conducted. Feasibility and preliminary outcomes were examined using nonparametric tests.

RESULTS

Preliminary results indicate that the ADAPT treatment is feasible, acceptable, and potentially effective for youth with FAPD. Treatment completers reported that they enjoyed the program and used the skills to manage their pain and worry. Results also indicated that the majority of participants experienced a reduction in anxiety and several reported reductions in pain and functional disability levels.

CONCLUSIONS

Findings from this study suggest that targeting both pain and anxiety may positively impact outcomes in youth with FAPD. The ADAPT intervention has the potential to provide a cost effective and practical application of cognitive behavioral therapy using an innovative combination of in-person and technology-based platforms. Overall, the ADAPT intervention is a promising and innovative intervention to improve the outcomes of youth with FAPD.

Autonomic arousal in anxious and typically developing youth during a stressor involving error feedback

Anxiety has been proposed to influence psychophysiological reactivity in children and adolescents. However, the extant empirical literature has not always found physiological reactivity to be associated with anxiety in youth. Further, most investigations have not examined psychophysiological reactivity in real time over the course of acute stress. To test the impact of anxiety disorder status on autonomic arousal in youth, we compared youth with primary anxiety disorders (N = 24) to typically developing (TD) youth (N = 22) on heart rate (HR), heart rate variability (HRV), and respiratory sinus arrhythmia (RSA) during an acute stressor in which youth received error-related feedback. We also conducted exploratory analyses on youth performance during the task. Youth ages 9-17 participated in the arithmetic portion of the Trier Social Stress Test for Children (Buske-Kirschbaum et al., Psychosom 59:419-426, 1997), during which time they received consecutive, standardized feedback that they made calculation errors. Results indicated that, compared to their TD counterparts, the anxious group demonstrated elevated HR and suppressed HRV during initial provision of error feedback and during the recovery period. No group differences were found for RSA. Additionally, overall TD youth made a greater proportion of errors than anxious youth. Clinically, these findings may provide preliminary support for anxious youth exhibiting physiological reactivity in response to receipt of error-related feedback, and may have implications for understanding biological processes during stress. This work underscores the need for further study of when and how anxiety may influence autonomic reactivity over the course of stress.

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.

Treatment of Functional Abdominal Pain With Antidepressants: Benefits, Adverse Effects, and the Gastroenterologist's Role

OBJECTIVES

Pediatric functional abdominal pain is often treated with tricyclic antidepressants (TCAs) and selective serotonin reuptake inhibitors (SSRIs). The aim is investigating antidepressant use for treatment efficacy, correlation of response to psychiatric factors, and impact of adverse effects in regard to physicians' prescribing patterns.

METHODS

Retrospective review (2005-2013) children (5-21 years old) with functional abdominal pain treated with SSRI or TCA. Of the 531 cases with functional abdominal pain, 192 initiated SSRIs or TCAs while followed by gastroenterology. Charts reviewed for symptoms, adverse effects, and response: decreased pain or increased daily functioning.

RESULTS

Sixty-three of 84 (75%) SSRI patients improved, 56 of 92 (61%) TCA patients improved (P = 0.03). Logistic regression controlling for psychiatric factors: SSRI remained significant over TCA (P = 0.04). Thirty-two of 67 (48%) patients with constipation received TCAs and 26 of 45 (58%) patients with diarrhea received SSRIs (P = 0.64). Three SSRI patients reported gastrointestinal effects, all diarrheal-type symptoms, and 2 TCA patients reported gastrointestinal effects, both constipation, in all it led to discontinuation. Thirteen (29%) of diarrheal-type patients reported adverse effects causing discontinuation as compared to 7 (8%) in the constipation group (P = .01). Twenty-one (25%) SSRI patients reported adverse effects with 5 (6%) mood disturbances. Twenty (22%) TCA patients reported adverse effects, 13 (14%) with mood disturbances (P = .07). Overall, 12 (14%) SSRI patients discontinued medication due to adverse effects, whereas 16 (17%) TCA patients (P = 0.24) did.

CONCLUSIONS

Patients had significantly greater response to SSRIs than TCAs, remaining significant after controlling for psychiatric factors. Little significance is given to patient's associated gastrointestinal symptoms, frequently resulting in adverse effects and termination of medication.

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.

Longitudinal synergies between cortisol reactivity and diurnal testosterone and antisocial behavior in young adolescents

The aims were to identify the correspondence between simultaneous, longitudinal changes in cortisol reactivity and diurnal testosterone and to test the hypothesis that cortisol reactivity and diurnal testosterone interact so as to influence antisocial behavior. Participants were 135 children and young adolescents assessed at 6-month intervals over 1 year. Upon enrollment girls were age 8, 10, or 12 years (N = 69, M = 10.06 years) and boys were age 9, 11, or 13 years (N = 66, M = 10.94 years). Assessments included Tanner staging by a nurse, cortisol reactivity (Trier Social Stress Test for Children), diurnal testosterone, and interviews and questionnaires. Growth models showed that cortisol reactivity and diurnal testosterone basal levels (intercept) and rate of change (slopes) were not related, suggesting different mechanisms of growth. Longitudinal regression analyses assessed cortisol reactivity and diurnal testosterone longitudinally. The interactions of cortisol reactivity and diurnal testosterone showed that when diurnal testosterone was low, boys with low cortisol reactivity were reported to have more behavior problems (i.e., oppositional defiant disorder symptoms and attention problems) than when testosterone was high. In addition, when diurnal testosterone was high, boys with high or moderate cortisol reactivity were significantly higher on total antisocial behavior, attention behavior problems, and oppositional defiant disorder symptoms than when testosterone was low or moderate. The results were similar but less frequent for girls. These findings advance the science of young adolescence by showing the interaction between preexisting sensitivity to stressors and the normative testosterone changes of puberty and antisocial behavior.

Thinking anxious, feeling anxious, or both? Cognitive bias moderates the relationship between anxiety disorder status and sympathetic arousal in youth

Cognitive bias and physiological arousal are two putative markers that may underlie youth anxiety. However, data on relationships between cognitive bias and arousal are limited, and typically do not include behavioral measurement of these constructs in order to tap real-time processes. We aimed to examine the relationship between performance-based cognitive bias and sympathetic arousal during stress in clinically anxious and typically-developing youth. The sample included children and adolescents ages 9 to 17 (Mean age=13.18, SD=2.60) who either met diagnostic criteria for primary generalized anxiety, social phobia, or separation anxiety (N=24) or healthy controls who had no history of psychopathology (N=22). Youth completed performance-based measures of attention and interpretation bias. Electrodermal activity was assessed while youth participated in the Trier Social Stress Test for Children (TSST-C; Buske-Kirschbaum, Jobst, & Wustmans, 1997). A mixed models analysis indicated significant linear and non-linear changes in skin conductance, with similar slopes for both groups. Interpretation bias, but not attention bias, moderated the relationship between group status and sympathetic arousal during the TSST-C. Arousal trajectories did not differ for anxious and healthy control youth who exhibited high levels of threat interpretation bias. However, for youth who exhibited moderate and low levels of interpretation bias, the anxious group demonstrated greater arousal slopes than healthy control youth. Results provide initial evidence that the relationship between anxiety status and physiological arousal during stress may be moderated by level of interpretation bias for threat. These findings may implicate interpretation bias as a marker of sympathetic reactivity in youth. Implications for future research and limitations are discussed.

Preoperative Distress Factors Predicting Postoperative Pain in Adolescents Undergoing Surgery: A Preliminary Study

The purpose of this study was to determine if preoperative distress factors could be used as predictors of postoperative pain in adolescents scheduled for spinal fusion surgery. Patients reporting the presence of pain before surgery reported greater pain intensity at postoperative day (POD) 1 (p = .033), POD 2 (p = .008) and at follow-up 6 weeks after surgery (p = .0001). Preoperative trait anxiety was associated with pain intensity before surgery (p = .002) but not with postoperative pain intensity (p > .05). Salivary cortisol concentrations did not differentiate between anxious and nonanxious patients based on anxiety trait (p = .21) and was not associated with postoperative pain intensity (p > .05). These findings suggest that preoperative distress factors do not predict postoperative pain intensity in the acute and intermediate period. The presence of preoperative pain was the best predictor of postoperative pain intensity, suggesting that preoperative pain assessment will identify patients at an elevated risk for intense postoperative pain.

Screening for Psychosocial and Family Risk in Pediatric Gastrointestinal Disorders

OBJECTIVES

Screening for psychosocial comorbidity is recommended for pediatric patients presenting at an initial gastroenterology (GI) outpatient consultation. We developed and evaluated the psychometric properties of the GI Screener to address the need for a screening tool specific to pediatric GI patients.

METHODS

128 patients (8-18 years old, 63% female) and 126 parents completed age-specific versions of the GI Screener and 3 validated psychosocial comparison instruments (The Behavioral Assessment System for Children, The Functional Disability Inventory, The General Functioning scale of the Family Assessment Device) at their initial GI consultation. (30%) of families repeated the measures 2 weeks later. We identified GI Screener content domains and retained items using exploratory factor analysis. We evaluated internal consistency, construct validity, cross-informant reliability, and test-retest reliability of the trimmed measures.

RESULTS

Exploratory factor analysis identified 2 factors in both the parent and child scales: Symptom Impact and Emotional Functioning. Internal consistency estimates for the trimmed scales were good (Cronbach's alpha >0.75) for both Child and Parent scales. We found that the GI Screener for both patient and parents had good construct validity. Cross-informant reliability between Parent and Child scales at baseline had an estimated correlation of 0.56, while intra class correlation coefficients between baseline and 2-week scores showed high test-retest reliability (>0.7).

CONCLUSIONS

The GI Screener is a brief, valid and reliable measure that can aid in identifying families who are at high risk for psychosocial comorbidity facilitating the targeted delivery of psychosocial intervention and efficient use of health care resources.

Possible Involvement of Avoidant Attachment Style in the Relations Between Adult IBS and Reported Separation Anxiety in Childhood

Irritable bowel syndrome (IBS) in adults as well as separation anxiety disorder (SAD) and recurrent abdominal pain (RAP) in childhood are associated with anxiety and somatization. Our aim was to examine possible associations between IBS in adulthood and SAD in childhood. Patients with IBS and healthy subjects completed a demographic questionnaire, the Separation Anxiety Symptom Inventory (SASI), the Somatization Subscale of Symptom Checklist-90-R (SCL-90-R), the Attachment Style Questionnaire, and a retrospective self-report questionnaire regarding RAP. Compared with controls, patients with IBS were characterized by an avoidant attachment style and scored higher on the SCL-90-R scale regarding the tendency to somatization (25.35 ± 7.47 versus16.50 ± 4.40, p < 0.001). More patients with IBS (25% versus 7.5%) reported RAP in childhood, but contrary to prediction, also had significantly lower SASI scores. Adults with IBS were characterized by somatization, insecure attachment style and recalled higher rates of RAP and surprisingly less symptoms of SAD in childhood. Based on these results, an etiological model for IBS is suggested, in which an avoidant attachment style and a tendency to somatization play an important role in the development of IBS.

[Stress related correlates of anxiety and depression in girls with chronic headache]

Chronic headache in adolescents is frequent and often associated with anxiety and depression. The present study investigated, whether psychological and physical stress symptoms have an infl uence on the occurrence of anxiety and depression and what is the role of stress coping. The sample consisted of 77 15 years old girls with chronic headache and 72 girls, who served as controls. Stress symptoms and stress coping were measured with the Stressverarbeitungsfragebogen für Kinder und Jugendliche (Coping with Stress Questionnaire for Children and Adolescents), depression was assessed by the Depression Inventory for Children and Adolescents, anxiety by the State-Trait Anxiety Inventory for Children. Linear regression was used to analyze the relationship between stress factors and anxiety resp. depression. Physical stress symptoms were related to anxiety, but not to depression. Coping strategies of the depressed as well as the anxious children were characterized by stress reinforcing behaviors. The results point to focusing on physical symptoms in the anxious headache patients and to avoidance coping in the depressed children.

Anxiety and physiological responses to the Trier Social Stress Test for Children in adolescents with cyclic vomiting syndrome

This study compared anxiety and physiological responses during the Trier Social Stress Test for Children (TSST-C) in adolescents. 38 subjects (26 females) were enrolled: 11 cyclic vomiting syndrome (CVS), 11 anxiety, and 16 controls. Salivary cortisol, α-amylase and heart rate variability (HRV) were assessed during the TSST-C. Anxiety was measured by the Screen for Childhood Anxiety Related Emotional Disorders (SCARED), Anxiety Disorders Interview Schedule, and State-Trait Anxiety Inventory for Children (STAI-C). 11 anxiety and 7 CVS subjects had ≥1 anxiety disorder. 82% in the anxiety and CVS groups met criteria for an anxiety disorder on the SCARED. Combining groups, cortisol increased from baseline to recovery during the TSST-C (p=0.0004) and the stressor to recovery (p=0.005). α-amylase did not differ during the TSST-C for the total sample, but increased for anxiety compared to controls from baseline to recovery (p=0.01). HRV decreased during the stressor (p=0.0001) and increased at recovery (p=0.004). No associations were found between biomarkers and trait anxiety. Associations were found between baseline HRV and pre-test state anxiety (r=-0.406, p=0.012) and between recovery HRV and post-test state anxiety (r=-0.501, p=0.002) for the total sample. Anxiety is prevalent in CVS warranting screening. HRV may serve as a biomarker for evaluating stress as a potential trigger for CVS episodes. State but not trait anxiety was associated with changes in HRV, suggesting acute anxiety may be more relevant in linking stress and CVS episodes.

Réactivité physiologique et conscience intéroceptive dans les troubles anxieux pédiatriques : une revue conceptuelle et empirique

L’intéroception, correspondant à la capacité de prendre conscience des sensations corporelles (SC) et réponses physiologiques, est supposée jouer un rôle majeur dans l’émergence de la réponse anxieuse. Chez les adultes, différentes études ont montré une altération des processus intéroceptifs en lien avec l’anxiété, qui s’associe à une sensibilité intéroceptive accrue et, paradoxalement, à une surestimation de l’activité physiologique du corps. Dans la mesure où les modèles cognitifs de l’anxiété insistent sur le rôle de ces processus dans l’étiologie et le maintien de l’anxiété et des troubles anxieux, l’étude de ces processus chez l’enfant souffrant d’anxiété est de premier intérêt. Dans cette revue empirique, nous nous intéresserons à la conscience que l’enfant anxieux a de ses SC et au rôle que celle-ci joue dans la pathogenèse du trouble. Dans la mesure où l’intéroception s’appuie sur la conscience de l’expérience physiologique et notamment des réponses cardiovasculaires, nous commencerons par présenter les données relatives à la réactivité cardiaque dans les troubles anxieux pédiatriques. Après une mise au point conceptuelle, nous synthétiserons ensuite les connaissances actuelles provenant des études ayant investigué les processus intéroceptifs chez l’enfant anxieux. Nous conclurons ce travail par une série de propositions pour les recherches futures.

Tic Frequency Decreases during Short-term Psychosocial Stress - An Experimental Study on Children with Tic Disorders

It has been suggested that psychosocial stress influences situational fluctuations of tic frequency. However, evidence from experimental studies is lacking. The current study investigated the effects of the Trier Social Stress Test (TSST-C) on tic frequency in 31 children and adolescents with tic disorders. A relaxation and a concentration situation served as control conditions. Patients were asked either to suppress their tics or to "tic freely." Physiological measures of stress were measured throughout the experiment. The TSST-C elicited a clear stress response with elevated levels of saliva cortisol, increased heart rate, and a larger number of skin conductance responses. During relaxation and concentration, the instruction to suppress tics reduced the number of tics, whereas during stress, the number of tics was low, regardless of the given instruction. Our study suggests that the stress might result in a situational decrease of tic frequency.

Panel manipulation in social stress testing: The Bath Experimental Stress Test for Children (BEST-C)

BACKGROUND

Whilst acute stress paradigms in adults make use of adult panel members, similar paradigms modified for child participants have not manipulated the panel. Most work has utilised an audience of adult confederates, regardless of the age of the population being tested. The aim of this study was to trial a social stress test for children that provided a meaningful environment using age-matched child peers as panel actors.

METHODS

Thirty-three participants (7-11 years) underwent the Bath Experimental Stress Test for Children (BEST-C). Based on the Trier Social Stress Test (TSST), it comprises a shortened six-minute public speaking task and four-minute maths challenge. It differs from previous stress tests by using age-matched children on the panel, pre-recorded and presented as a live feed, and includes an expanded manipulation check of subjective experience. Salivary cortisol was assessed at four time points, pre-post stress testing; life events, daily hassles and coping strategies were measured through questionnaires. A simple numerical coding scheme was applied to post-test interview data.

RESULTS

The BEST-C generated a typical stress and adaptation response in salivary cortisol (p=.032). Age and gender differences were observed during recovery. Cortisol responses mapped directly onto three distinct subjective response patterns: (i) expected response and recovery; (ii) expected response, no recovery; (iii) no response.

CONCLUSIONS

The BEST-C, utilising child confederates of participant target age is a meaningful social stress test for children. This is the first social stress test developed specifically for children that manipulates panel characteristics by using child confederates and a pre-recorded sham panel. Greater cortisol responses to the test were also found to match subjective verbal accounts of the experience. It offers a meaningful acute stress paradigm with potential applications to other child and adolescent age groups. Furthermore, it leads the way in the use of panel manipulation in social stress testing.
