Assessment of Pain Anxiety, Pain Catastrophizing, and Fear of Pain in Children and Adolescents With Chronic Pain: A Systematic Review and Meta-Analysis

Perceived discrimination and pain outcomes among black adults with chronic musculoskeletal pain: identifying modifiable psychosocial risk factors

Chronic musculoskeletal pain (CMP) is highly prevalent, frequently associated with negative health outcomes, and disproportionately impacts Black Americans. Perceived racial and ethnic discrimination has emerged as a factor that may influence the experience of chronic pain in this population. Identifying modifiable psychosocial factors that influence the link between perceived discrimination and pain and that can be directly targeted in treatment is vital to reducing the disproportionate burden of CMP among Black individuals. The present study examines the moderating role of five risk factors (i.e., pain avoidance, pain fusion, experiential avoidance, pain catastrophizing, and pain anxiety) on the relationship between perceived discrimination and pain outcomes (i.e., pain intensity and interference) in a sample of 401 Black adults with CMP. We recruited 401 Black individuals (Mage = 35.98, 51.9% female) with self-reported CMP and assessed their self-reported perceived discrimination, pain intensity, pain interference, and pain-related psychosocial risk factors. Results indicated that higher scores on each of the psychosocial risk factors (i.e., pain avoidance, pain fusion, experiential avoidance, pain catastrophizing, and pain anxiety) were significantly associated with greater pain intensity and pain interference (all ps < 0.01). Further, pain avoidance (B = 0.12, p = .006), pain fusion (B = 0.13, p = .002), and pain anxiety (B = 0.13, p = .002) each significantly moderated the relation between perceived discrimination and pain intensity. Greater perceived discrimination was associated with greater pain intensity at higher levels of avoidance and fusion, and was associated with less pain intensity at lower levels of avoidance and pain anxiety. In interaction models predicting pain interference, both pain fusion (B = 0.14, p = .001) and pain anxiety (B = 0.10, p = .01) significantly moderated the relation between perceived discrimination and pain interference. Perceived discrimination was associated with greater pain interference at higher levels of pain fusion and pain anxiety, and was not associated with pain interference at lower levels of pain fusion and pain anxiety. The present findings provide important insights into psychosocial risk factors that moderate the link between perceived discrimination and pain outcomes, providing important clinical implications for the treatment of Black adults with chronic musculoskeletal pain.

The association between anxiety and depression symptoms and pain and function in adolescents and young adults with chronic pain: A meta-analysis

OBJECTIVE

Chronic pain in adolescents and young adults (AYAs) is associated with adverse functional and psychological outcomes; however, inconsistent findings across studies necessitate a comprehensive synthesis. This meta-analysis aimed to quantify associations between anxiety, depression, and pain/functional outcomes, and explore study and sample moderators, such as age, sex, pain duration, recruitment setting, and measurement tools.

METHODS

We searched MEDLINE, PsycINFO, CENTRAL, and Embase through May 2024. included 57 studies (N = 12,603) of AYAs aged 12-25 years with chronic pain. Risk of bias and GRADE assessments were conducted. Pearson r correlations were meta-analyzed using a random-effects model.

RESULTS

Small associations were found between anxiety, depression, and heightened pain intensity (r = 0.20, 0.24). Moderate-to-large associations were observed between anxiety, depression, and disability (r = 0.32, 0.34), pain interference (r = 0.47, 0.51), pain catastrophizing (both r = 0.50), and poorer quality of life (r = -0.56, -0.61). Anxiety had stronger correlations with pain intensity and catastrophizing in samples with more males. Anxiety measure moderated the anxiety-pain intensity relationship. Depression had stronger correlations with pain intensity for shorter pain duration, and catastrophizing and pain interference for longer pain durations. The depression-catastrophizing association was stronger in older samples.

CONCLUSION

Anxiety and depression significantly impact the chronic pain experience in AYAs, with stronger effects on functional outcomes and quality of life than pain intensity. Tailored interventions that consider age, sex, and pain duration may enhance treatment outcomes in this population.

Comparison of Pain Characteristics, Strength, and Movement Patterns in Adolescents With Juvenile Fibromyalgia and High Versus Low Fear of Movement

Physical activity avoidance and fear of movement (FOM) is often observed in individuals with chronic musculoskeletal pain, along with difficulties coping with pain. There is little research regarding how FOM may also relate to reduced physical strength and altered movement patterns that may perpetuate a cycle of pain, FOM, and disability. The objective of this observational study was to compare how adolescents with juvenile fibromyalgia (JFM) exhibiting high versus low FOM (Tampa Scale of Kinesiophobia-11) differed on patient-reported measures of pain, fatigue, catastrophizing and pain interference, and performance-based measures of strength, postural control, and biomechanical function. Participants were youth with JFM (N = 135, Meanage = 15.6 years, 88.9% female) enrolled in an ongoing clinical trial who completed self-report questionnaires and standardized tests, including knee and hip strength, the Star Excursion Balance Test, and the Drop Vertical Jump (with 3 dimensional motion capture). Participants were categorized into Low, Medium, and High FOM groups based on Tampa Scale of Kinesiophobia-11 tertile scores. Relative to the Low FOM group, the High FOM group reported significantly greater fatigue, pain interference and catastrophizing, as well as reduced dominant leg knee strength. Additionally, those with high FOM showed altered lower-extremity movement patterns. This preliminary study highlights the importance of combining self-reported measures of symptoms and functioning with physical assessments to gain a more comprehensive view of the impact of FOM in patients with chronic musculoskeletal pain. The results could inform the development of more precise interventions to reduce FOM using a combination of behavioral and exercise-based interventions.

PERSPECTIVE

The results of this study demonstrate the association between FOM, fatigue and pain interference in adolescents with JFM, as well as preliminary evidence for altered movement patterns in that may predispose them to further pain/injury and activity avoidance.

Examining tools for assessing the impact of chronic pain on emotional functioning in children and young people with cerebral palsy: stakeholder preference and recommendations for modification

PURPOSE

To firstly identify tools for assessing the impact of chronic pain on emotional functioning in children and young people with cerebral palsy (CP), and secondly identify suggestions to improve their relevance, comprehensiveness, comprehensibility and feasibility for the CP population. Improving assessment of the impact of pain on emotional functioning can enhance quality of life by improving access to interventions for pain-related physical disability, anxiety and depression.

METHODS

Ethics approval was granted through the Women's and Children's Health Network Human Research Ethics Committee (2022/HRE00154). A mixed methods study with people with lived experience and clinicians, and guided by the Consensus-based Standards for Measurement Instruments (COSMIN), was undertaken. An online survey identified the highest rated tools for validation and/or modification for young people with CP and chronic pain. Focus groups and interviews investigated content validity and feasibility of the tools identified as highest rated.

RESULTS

The Fear of Pain Questionnaire for Children-SF (FOPQ-C-SF) and Modified Brief Pain Inventory (mBPI) were the highest rated for pain coping and multidimensional assessment (respectively) from the online survey (n = 61) of eight tools presented. Focus group and interview data (n = 30), including 58 unique modification suggestions, were coded to six categories: accessibility, comprehensibility, feasibility, relevance, presentation and comprehensiveness.

CONCLUSION

Potential modifications have been identified to improve the appropriateness and feasibility of the FOPQ-C-SF and mBPI for children and young people with CP. Future research should implement and test these modifications, prioritising the involvement of people with lived experience to ensure their needs are met alongside clinicians.

Psychological treatments for temporomandibular disorder pain-A systematic review

OBJECTIVE

Temporomandibular disorders (TMD) are common. They affect abilities for carrying out daily tasks and influence different psychological aspects. In addition to standard treatment, psychological treatments have been suggested. The aim was to investigate the effects of psychological treatments on patients with painful TMD in a short- and long-term perspective.

MATERIALS AND METHODS

An electronic search was conducted in the databases MEDLINE, CINAHL, EMBASE, the Cochrane Central Registry of Controlled Trials (CENTRAL), and Web of Science for randomized clinical trials (RCTs) reporting psychological interventions for TMD. Registered beforehand in PROSPERO (CRD42022320106). In total, 18 RCTs were included; six RCTs that could be used in the meta-analysis, and all 18 RCTs were used in the narrative synthesis. Risk of bias was assessed by the Cochrane's tool for assessing risk of bias and certainty of evidence by GRADE.

RESULTS

The narrative synthesis indicates that psychological treatment options seem equivalent to standard treatment for painful TMD. The meta-analysis showed that a combination of psychological treatment and standard treatment and manual treatment (very low-quality evidence) are significantly better in pain reduction than just counselling and standard treatments of TMD.

CONCLUSION

This study indicates that psychological treatments seem to reduce pain intensity in individuals with painful TMD, and that the effect seems to be equally good as standard treatment. However, a combination of psychological treatments and standard treatments seems to have an even better effect. This indicates that psychological treatments are promising as an additional treatment approach for painful TMDs.

Measurement properties and feasibility of chronic pain assessment tools for use with children and young people with cerebral palsy

PURPOSE

Chronic pain assessment tools exist for children, but may not be valid, reliable, and feasible for populations with functional, cognitive or communication limitations, for example, cerebral palsy (CP). This study aimed to (i) identify chronic pain assessment tools used with children and young people and rate their measurement properties; (ii) develop a CP specific feasibility rating tool to assess the feasibility of tools in CP; and (iii) categorise tools according to reporting method.

MATERIALS AND METHODS

Assessment tools were identified by literature review. Their measurement properties were rated using the COnsensus based standards for the Selection of health Measurement INstruments. The CP specific Feasibility Rating Tool was developed and used to rate the tools.

RESULTS

Fifty-seven chronic pain assessment tools were identified. Six have content validity for CP, four of these use proxy-report. Forty-two tools were considered feasible for people with CP; 24 self report and 18 observational/proxy-report. Only the Paediatric Pain Profile has content validity and feasibility for people with CP unable to self-report.

CONCLUSIONS

There are few valid, reliable and feasible tools to assess chronic pain in CP. Further research is required to modify tools to enable people with cognitive limitations and/or complex communication to self-report pain.

Experiential Avoidance as a Factor in Generalized Psychological Vulnerability: In the Relationship Between Chronic Pain and Pain Anxiety With Pain Disability

BACKGROUND

Pain is a major socio-psychological problem worldwide. Chronic pain has a negative effect on areas of psychological functioning such as depression, anxiety, and perceived stress.

AIM

The present study investigated the mediating role of experiential avoidance in the relationship between chronic pain and pain anxiety with pain disability.

METHODS

Participants were treatment-seeking patients (N = 361) at an outpatient pain clinic in Shiraz (Fars, Iran). The Multidimensional Pain Inventory (MPI), Pain Anxiety Symptom Scale (PASS-20), Pain Disability Questionnaire (PDQ), and Acceptance and Action Questionnaire-II (AAQ-II) were used to measure multidimensional pain, anxiety, pain disability, experiential avoidance, and pain severity.

RESULTS

The results of the correlation revealed that a significant relationship exists between multidimensional pain and pain anxiety, pain disability, and experiential avoidance. Experiential avoidance mediated the associations from multidimensional pain and pain disability significantly. Also, experiential avoidance moderated associations between pain anxiety and pain disability significantly. In general, Structural Equation Modeling (SEM) showed that experiential avoidance mediated the relationship between multidimensional pain and pain anxiety with pain disability.

CONCLUSION

In general, the results revealed that experiential avoidance can mediate the relationship among pain, pain anxiety, and pain disability as a maladaptive regulation strategy. The results obtained from this study seem to introduce experiential avoidance as a vulnerability factor effectively.

Weak Relationships Between Psychological Factors and Experimental Pain Outcomes in Pain-Free Individuals: An Aggregate Analysis of 8 Studies

Although psychological factors such as anxiety, depression, and pain catastrophizing are known to influence pain outcomes in chronic pain populations, there are mixed results regarding whether they influence experimental pain outcomes in pain-free individuals. The objectives of this study were to determine the associations between psychological factors and experimental pain outcomes in pain-free adolescents and adults. Relationships between anxiety, depression, and pain catastrophizing and experimental pain outcomes across 8 different studies (total N = 595) were examined in different populations of pain-free adult and adolescent participants. Analyses were conducted with and without controlling for sex, age, and race. Studies were analyzed separately and as part of an aggregate analysis. Individual study analyses resulted in 136 regression models. Of these, only 8 models revealed a significant association between psychological factors and pain outcomes. The significant results were small and likely due to Type 1 error. Controlling for demographic factors had minimal effect on the results. The aggregate analyses revealed weak relationships between anxiety and pressure pain threshold (Fisher's z = -.10 [-.19, -.01]), anxiety and cold pain intensity ratings (Fisher's z = .18 [.04, .32]), and pain catastrophizing and pressure pain threshold (Fisher's z = -.14 [-.26, -.02]). Sample size calculations based on the aggregate analyses indicated that several hundred participants would be required to detect true relationships between these psychological factors and pain measures. The overall negative findings suggest that in pain-free individuals, anxiety, depression, and pain catastrophizing are not meaningfully related to experimental pain outcomes. PERSPECTIVE: Psychological variables have been shown to predict pain outcomes in chronic pain populations but these relationships may not generalize to pain-free populations. An analysis of 595 pain-free individuals across 8 studies in our lab revealed that anxiety, depression, and pain catastrophizing were not meaningfully related to experimental pain outcomes.

A systematic review of pre-injury anxiety disorder and post-concussion outcomes in youth and young adult athletes

Pre-injury anxiety disorder may be a risk factor for poor outcomes following sportsrelated concussion. A systematic review was performed to characterize the relationship between pre-injury anxiety disorder and post-concussion symptom presentation and recovery time after sports-related concussions among children, adolescents, and young adults. A PRISMA-compliant literature search was conducted in Ovid MEDLINE, PsycINFO, EMBASE, and Scopus for articles published up to 25 January 2024. The initial query yielded 1358 unique articles. Articles that analyzed the relationship between pre-injury anxiety disorder and post-concussion symptoms and recovery time were included. A final cohort of 11 articles was extracted, comprising a total of 8390 study participants, of whom 921 had a history of pre-injury anxiety disorder. Pre-injury anxiety disorder was associated with prolonged time to return to sports activity and an increased incidence of physical, emotional, cognitive, and sleep-related symptoms. While the results of this review suggest an association between pre-injury anxiety disorder and post-concussion symptoms and recovery time, future studies should be more stringent regarding standardized anxiety disorder definitions, longitudinal assessment of post-concussion symptoms, anxiety disorder subtypes, and anxiety treatment history.

Characteristics and outcomes of youth with functional seizures attending intensive interdisciplinary pain treatment

Functional seizures (FS) can be debilitating and negatively impact quality of life. Yet intervention research for FS is limited, especially for youth. This study examined clinical characteristics and outcomes of youth with FS (13-23 years) presenting to a pediatric intensive interdisciplinary pain treatment (IIPT) program in the midwestern United States. Sixty youth (mean age = 16.5 years; 83.3 % female) met inclusion criteria. At intake, comorbid chronic pain, somatic symptoms, autonomic dysfunction, eating and weight disturbances, and mental health concerns were common. Despite this high symptom burden, youth with FS reported significant improvements in functioning measured with the Functional Disability Inventory, t(53) = 9.80, p <.001, d = 1.32; depression measured with the Center for Epidemiological Studies - Depression Scale for Children, t(53) = 6.76, p <.001, d = 0.91; anxiety measured with the Spence Children's Anxiety Scale, t(53) = 3.97, p < .001, d = 0.53; and catastrophizing measured with the Pain Catastrophizing Scale for Children, t(53) = 6.44, p <.001, d = 0.86, following completion of the program, suggesting that IIPT may be an effective treatment option for highly disabled and emotionally distressed youth with FS. Future research is needed to continue to refine best practices for youth with FS to reduce suffering and improve outcomes.

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.

Understanding the impacts of chronic pain on autistic adolescents and effective pain management: a reflexive thematic analysis adolescent-maternal dyadic study

OBJECTIVE

Sensory elements are core features in chronic pain and autism, yet knowledge of the pain experience in autistic adolescents is limited. Little is known regarding how autistic adolescents experience chronic pain, manage their pain and perceive psychological treatment for their chronic pain.

METHODS

Ten autistic adolescents (6 female, 3 male, and 1 self-identified as agender) with chronic pain and their mothers (n = 10) participated in semistructured interviews concerning their perceptions of living with chronic pain. Participants were recruited from U.K. pain management services. According to preference, interviews were conducted individually (n = 10) or dyadically (n = 10 participants across 5 dyads). Data were analyzed using inductive reflexive thematic analysis.

RESULTS

Two themes were generated. Theme 1, "overstimulated and striving for control" described how adolescents' experience of heightened sensitivity enhanced adolescents' levels of anxiety and subsequent pain, illustrating a reciprocal relationship between anxiety, pain, and sensory elements. Theme 2, "not everyone fits the mold" captured how autistic adolescents positioned themselves as distinct from others due to the unique nature of being autistic and living with pain. This sense of difference negatively impacted adolescents' ability to engage with and benefit from the standard treatment for chronic pain.

CONCLUSIONS

Findings suggest that autistic adolescents living with pain experience pain and face barriers to effective pain treatment. Our results identify the need for educational resources to facilitate clinicians to better understand the experience of autistic adolescents living with pain. In turn, such understanding may improve treatment and outcomes in this population.

Predictors of improvement in community adolescents with chronic neck pain: A secondary analysis using different improvement criteria

BACKGROUND

Interventions based on pain neuroscience education and exercise have emerged as effective in the management of chronic neck pain in adolescents. No studies have explored factors that might be associated with recovery in adolescents with neck pain.

OBJECTIVE

To explore predictors of improvement after an intervention based on exercise and pain neuroscience education.

DESIGN

Secondary analysis of a randomized trial.

SETTING

Community.

PARTICIPANTS

127 community adolescents with neck pain.

INTERVENTIONS

Blended-learning intervention based on exercise and pain neuroscience education.

MAIN OUTCOME MEASURES

A set of variables including sociodemographic data, pain characteristics, physical activity, disability, sleep, catastrophizing, fear of movement, self-efficacy, symptoms of central sensitization, knowledge of pain neuroscience, pressure pain thresholds, and neck muscles endurance were used to predict a clinical response at 1 week after intervention and at 6-month follow-up.

RESULTS

Different predictors of improvement and non-improvement to intervention were found, but common predictors were not found for all the improvement criteria explored and time points.

CONCLUSIONS

These findings suggest that using different criteria to characterize adolescents with neck pain as improved and non-improved after pain neuroscience education and exercise have an effect on the variables associated with a response to the intervention.

The validity and reliability of the Turkish version of the Fear of Pain Questionnaire for Children-Short Form (FOPQC-SF) in children and adolescents with juvenile idiopathic arthritis

OBJECTIVE

The aim of this study was to investigate the validity and reliability of the Turkish version of the Fear of Pain Questionnaire for Children-Short Form (FOPQC-SF) in children/adolescents with juvenile idiopathic arthritis (JIA).

METHODS

To evaluate validity of FOPQC-SF, 70 children/adolescents with JIA were included. Data were collected using Pediatric Quality Of Life Inventory 3.0. Module Arthritis (PedsQL), Childhood Health Assessment Questionnaire (CHAQ) and Juvenile Arthritis Disease Activity Score (JADAS).To determine the reliability of the FOPQC-SF, test-retest was performed at one-week intervals on participants who had not made any changes to their pharmacological treatment and had not received any additional treatment.

RESULTS

With factor restrictions, items of Turkish version of FOPQC-SF were found acceptable for a 2-factor structure (fear:4 items; avoidance:6 items)(RMSEA = 0.058, GFI = 0.890, X2 = 40.667 X2/df = 1.196). With no restrictions, items of Turkish version of FOPQC-SF were found to be excellent for a 3-factor structure (fear:3 items; avoidance:4 items; other:3 items) (RMSEA = 0.036, GFI = 0.909, X2 = 34.465, X2/df = 1.077).The Cronbach's alpha value of Turkish version of FOPQC-SF total was 0.865 (good). The intraclass correlation coefficient (ICC2,1) was 0.865 (very high). Fear and avoidance subscales and total score of Turkish version of FOPQC-SF had low to moderate correlation with CHAQ-disability index, CHAQ-pain, CHAQ-global evaluation, JADAS, PedsQL-child total, PedsQL-parent total (r:-0.283/-0.452)(p < 0.05). Other subscale of Turkish version of FOPQC-SF had low to moderate correlation with CHAQ-disability index, CHAQ-pain, PedsQL-parent total (r:0.286/0.318) (p < 0.05).

CONCLUSION

The Turkish version of FOPQC-SF was found to be clinically valid and reliable in children and adolescents with JIA.

Interoceptive beliefs moderate the link between physiological and emotional arousal during an acute stressor

Growing work suggests that interoception, that is, representations of one's internal bodily changes, plays a role in shaping emotional experiences. Past studies primarily examine how behavioral accuracy in detecting interoceptive signals (interoceptive ability) relates to emotional states, with less work examining self-reported interoceptive facets such as the characterizations of one's interoceptive abilities (interoceptive sensibility) or evaluative beliefs about the value versus danger of interoceptive signals (interoceptive beliefs). However, existing studies rarely examine physiological reactivity, behavioral, and self-reported dimensions of interoception together in the same sample. As such, it remains unclear whether and how much individual differences in interoceptive facets uniquely and in interaction with physiological reactivity may matter for emotional experience. Herein, 250 healthy young adults completed a heartbeat detection task assessing interoceptive ability and questionnaire measures of interoceptive sensibility and beliefs during an initial laboratory visit. At a follow-up session, 227 participants returned to undergo an acute psychosocial stressor. Measures of physiological arousal such as preejection period (PEP) and heart rate variability were acquired throughout the stressor with self-reported emotions acquired immediately after. Linear regressions revealed that greater sympathetic nervous system reactivity (i.e., PEP), poorer interoceptive ability (i.e., accuracy), and less positive interoceptive beliefs were related to more intense high arousal emotions during the stressor. Importantly, across models, interoceptive beliefs was the only interoceptive facet to moderate the concordance between physiological and emotional arousal. Implications for psychological theories of emotion, stress, and interoception are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Baseline Factors Associated with Pain Intensity, Pain Catastrophizing, and Pain Interference in Intensive Interdisciplinary Pain Treatment for Youth

Background: More could be known about baseline factors related to desirable Intensive Interdisciplinary Pain Treatment (IIPT) outcomes. This study examined how baseline characteristics (age, gender, child pain catastrophizing (PCS-C), pain interference, pain intensity, anxiety, depression, paediatric health-related quality of life (PedsQLTM), and parent catastrophizing (PCS-P)) were associated with discharge and 3-month follow-up scores of PCS-C, pain intensity, and pain interference. Methods: PCS-C, pain intensity, and pain interference T-scores were acquired in 45 IIPT patients aged 12-18 at intake (baseline), discharge, and 3-month follow-up. Using available and imputed data, linear mixed models were developed to explore associations between PCS-C, pain intensity, and pain interference aggregated scores at discharge and follow-up with baseline demographics and a priori selected baseline measures of pain, depression, anxiety, and PCS-C/P. Results: PCS-C and pain interference scores decreased over time compared to baseline. Pain intensity did not change significantly. Baseline PCS-C, pain interference, anxiety, depression, and PedsQLTM were associated with discharge/follow-up PCS-C (available and imputed data) and pain interference scores (available data). Only baseline pain intensity was significantly associated with itself at discharge/follow-up. Conclusions: Participants who completed the IIPT program presented with reduced PCS-C and pain interference over time. Interventions that target pre-treatment anxiety and depression may optimize IIPT outcomes.

Long-term Pain Symptomatology in PICU Survivors Aged 8-18 Years

BACKGROUND AND OBJECTIVES

Children discharged from the PICU often experience long-term physical, psychological, social and cognitive challenges, described as postintensive care syndrome. This study fills a critical gap by describing the long-term pain symptoms many children experience using child self-report.

METHODS

Participants in this cross-sectional study were children aged 8 to 18 years (and 1 parent, n = 64 dyads) who were 8 to 24 months post-PICU discharge. Participants completed measures assessing pain, psychosocial function, and treatment utilization. Health information relevant to the PICU admission was obtained from the electronic medical record.

RESULTS

Children were an average age of 14.3 years and 50% female. Average pain intensity in the past month was 3.65 (0-10 numeric rating scale), with 36% of children reporting pain ≥2 to 3 days a week. Youth with higher intensity (≥4) and more frequent pain (≥2-3 days a week) had greater pain catastrophizing, pain-related fear, anxiety, and sleep disturbance than those with less frequent and intense pain. Higher pain frequency was also associated with greater pain-related disability and depressive symptoms. Pain was not associated with any PICU-related variables abstracted from the electronic medical record. Parents reported children frequently accessed pain treatment services postdischarge; however, 37.5% reported the coronavirus disease 2019 pandemic impacted access to recommended services.

CONCLUSIONS

A significant portion of children experience pain post-PICU discharge. For many of these children, pain is frequent and is associated with impairments in psychosocial function. Future prospective research studies can be used to identify risk factors of poor pain outcomes so children can receive targeted interventions.

Cross-cultural adaptation and psychometric properties of Spanish Child Pain Anxiety Symptoms Scale

INTRODUCTION

Pain anxiety is a psychological component that can regulate and modulate the experience of pain in children and adolescents. It can also have an impact on the outcomes of surgical procedures, chronic pain management and psychological interventions. The aim of our study was to translate the Child Pain Anxiety Symptoms Scale (CPASS) into Spanish and assess the psychometric properties of the Spanish version.

PATIENTS AND METHODS

First, the CPASS was translated according to international guidelines. Secondly, to assess the psychometric properties of the translated version, we conducted an analysis in a paediatric sample. A total of 160 children, 49.37% female, with a mean age of 14.5 years (SD, 2.3; range, 8-18 years) completed pain catastrophising, health-related quality of life, pain interference and pain intensity scales. We assessed the following psychometric properties: construct validity (exploratory and confirmatory factor analysis), internal consistency, floor and ceiling effects and convergent validity (correlation of CPASS to the other completed questionnaires completed and with objective aspects of the health history).

RESULTS

In the exploratory factor analysis, the final 18-item version (having excluded items 18 and 19) of the CPASS was the best fit, with all items included in the hypothetical construct and exhibiting optimal factor loadings. The confirmatory factor analysis showed that the final 18-item, 4-factor model was adequate for the scale structure. We did not detect any floor or ceiling effects in the final version. Lastly, the results confirmed that the Spanish version has good internal consistency (Cronbach  α, 0.88) and an adequate convergent validity.

CONCLUSION

The Spanish CPASS exhibits good psychometric proprieties and it can be used to assess pain anxiety in the paediatric population.

Pain coping tools for children and young adults with a neurodevelopmental disability: A systematic review of measurement properties

AIM

To systematically identify and evaluate the measurement properties of patient-reported outcome measures (PROMs) and observer-reported outcome measures (parent proxy report) of pain coping tools that have been used with children and young adults (aged 0-24 years) with a neurodevelopmental disability.

METHOD

A two-stage search using MEDLINE, Embase, CINAHL, Web of Science, and PsycInfo was conducted. Search 1 in August 2021 identified pain coping tools used in neurodevelopmental disability and search 2 in September 2021 located additional studies evaluating the measurement properties of these tools. Methodological quality was assessed using the COnsensus-based Standards for the Selection of Health Measurement INstruments (COSMIN) guidelines (PROSPERO protocol registration no. CRD42021273031).

RESULTS

Sixteen studies identified seven pain coping tools, all PROMs and observer-reported outcome measures (parent proxy report) versions. The measurement properties of the seven tools were appraised in 44 studies. No tool had high-quality evidence for any measurement property or evidence for all nine measurement properties as outlined by COSMIN. Only one tool had content validity for individuals with neurodevelopmental disability: the Cerebral Palsy Quality of Life tool.

INTERPRETATION

Pain coping assessment tools with self-report and parent proxy versions are available; however, measurement invariance has not been tested in young adults with a neurodevelopmental disability. This is an area for future research.

Diagnostic criteria for temporomandibular disorders-INfORM recommendations: Comprehensive and short-form adaptations for children

BACKGROUND

The Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) are used worldwide in adults. Until now, no adaptation for use in children has been proposed.

OBJECTIVE

The aim of this study was to present comprehensive and short-form adaptations of Axis I and Axis II of the DC/TMD for adults that are appropriate for use with children in clinical and research settings.

METHODS

Global Delphi studies with experts in TMDs and in pain psychology identified ways of adapting the DC/TMD for children.

RESULTS

The proposed adaptation is suitable for children aged 6-9 years. Proposed changes in Axis I include (i) adapting the language of the Demographics and the Symptom Questionnaires to be developmentally appropriate for children, (ii) adding a general health questionnaire for children and one for their parents, (iii) replacing the TMD Pain Screener with the 3Q/TMD questionnaire and (iv) modifying the clinical examination protocol. Proposed changes in Axis II include (i) for the Graded Chronic Pain Scale, to be developmentally appropriate for children, (ii) adding anxiety and depression assessments that have been validated in children and (iii) adding three constructs (stress, catastrophising and sleep disorders) to assess psychosocial functioning in children.

CONCLUSION

The recommended DC/TMD, including Axis I and Axis II, for children aged 6-9 years, is appropriate for use in clinical and research settings. This adapted the first version for children includes changes in Axis I and Axis II changes requiring reliability and validity testing in international settings. Official translations to different languages according to INfORM requirements will enable a worldwide dissemination and implementation.

Parental experiences related to pediatric and adolescent chronic non-cancer pain: A qualitative exploration

PURPOSE

To explore parental experiences in personal functioning and parenting associated with having a child experiencing chronic non-cancer pain.

METHODS

Parents with children experiencing chronic pain were asked to fill out a survey prior to their initial Pediatric Pain Clinic or Pain Psychology appointment at a children's hospital in the southeastern United States. A retrospective analysis of qualitative data was conducted. Qualitative results from open-ended survey questions will be focused on within this manuscript.

FINDINGS

A total of 288 surveys were collected in this study, with 243 participants answering at least one qualitative question. Of participants who responded to open-ended survey questions, there were 88 responses to a question related to parental change, 73 to parental impact, and 239 to goals of the visit. Through thematic analysis, five qualitative themes were identified: Pain Central: The Hub, Juggling Life, Suffering Side by Side, Unrealized Dreams, and Gettin' it Under Control.

DISCUSSION

Parents do experience alterations in personal functioning and parenting as a result of having a child that experiences chronic non-cancer pain. Parents face struggles in many aspects of life including emotions, work, and interpersonal relationships. Theoretical considerations were discussed.

APPLICATION TO PRACTICE

Understanding the experiences parents have in raising a child with chronic pain is important in helping health care providers to recognize that this population may need interventions. This also assists in informing patient treatment, improving patient and parent care outcomes, and educating clinicians on how to better support parents.

[Psychological aspects of pain prevention : German version]

How to prevent the onset, maintenance, or exacerbation of pain is a major focus of clinical pain science. Pain prevention can be distinctly organised into primary, secondary, and tertiary prevention. Primary prevention describes avoiding hurt or pain, secondary prevention describes reducing pain when pain is unavoidable, and tertiary prevention describes preventing or reducing ongoing negative consequences such as high functional disability or distress due to chronic pain. Each poses separate challenges where unique psychological factors will play a role. In this short review article, we highlight psychological factors important to primary, secondary, and tertiary prevention and provide direction for the field. We present 2 case studies on secondary prevention in children and adolescents and tertiary prevention in adults with chronic pain. Finally, we provide research directions for progression in this field, highlighting the importance of clear theoretical direction, the identification of risk factors for those most likely to develop pain, and the importance of treatment.

Clinical Assessment of Mechanical Allodynia in Youth With Complex Regional Pain Syndrome: Development and Preliminary Validation of the Pediatric Tactile Sensitivity Test of Allodynia (Pedi-Sense)

Youth with complex regional pain syndrome (CRPS) commonly experience mechanical allodynia and disability. Assessment of mechanical allodynia is typically binary (present or absent), making it difficult to assess the quality and degree of mechanical allodynia before and after treatment. This study developed and validated the Pediatric Tactile Sensitivity Test of Allodynia (Pedi-Sense) to provide an easy way for rehabilitation clinicians to evaluate mechanical allodynia before and after intensive interdisciplinary pain treatment. The 6 Pedi-Sense items demonstrated adequate internal consistency reliability (CR) at admission (CR = .956) and discharge (CR = .973), reasonably fit the hypothesized linear model of stimulus intensity (P < .0001), and significantly loaded onto a single latent factor, mechanical allodynia (P < .0001), at admission and discharge. Pedi-Sense scores significantly correlated with disability (r_s = .40; P = .004) and pain catastrophizing (r_s = .33; P = .017) at admission. The Pedi-Sense appeared responsive to intervention as participants' total scores improved by 1.44 points (95% CI: .72, 2.15) after IIPT interventions that included daily tactile desensitization. However, test-retest and interrater reliability and the specific contribution of desensitization treatment to the overall success of multi-modal pain rehabilitation still needs to be evaluated. PERSPECTIVE: This article presents the development and preliminary validation of a novel clinical assessment of static and dynamic mechanical allodynia. The Pediatric Tactile Sensitivity Test of Allodynia (Pedi-Sense) allows rehabilitation clinicians to easily evaluate mechanical allodynia at the bedside with minimal training and simple equipment to guide desensitization treatment in clinical settings.

Chronic Pain and Its Impact on Child Mental Health: Management Challenges and Clinical Guidance for Child and Adolescent Psychiatrists

Chronic pain refers to recurrent or persistent pain that extends beyond the expected time of healing. In addition to the negative impact of chronic pain on a child's overall well-being and functioning in social and academic settings, chronic pain negatively impacts family functioning, caregiver well-being, and a family's financial resources.¹ Furthermore, youth with chronic pain frequently meet criteria for psychiatric disorders, such as mood and anxiety disorders, posttraumatic stress disorder, and disruptive disorders, and chronic pain increases the risk for suicidal behaviors and substance use on a long-term basis.^1,2 Comorbid psychiatric symptoms and behaviors among youth with chronic pain often add additional discomfort, dramatically reduce quality of life, exacerbate pain symptoms, and delay or prevent recovery.¹ Many youth do not receive ideal, multidisciplinary care.

Altered anterior insula functional connectivity in adolescent and young women with endometriosis-associated pain: Pilot resting-state fMRI study

BACKGROUND

Endometriosis is the leading cause of chronic pelvic pain. Alterations in brain functional connectivity have been reported in adult women with endometriosis-associated pain (EAP), however, it is still unknown if similar patterns of changes exist in adolescents.

METHODS

In this pilot study, resting-state fMRI scans were obtained from 11 adolescent and young women with EAP and 14 healthy female controls. Using a seed-to-voxel approach, we investigated functional connectivity between the anterior insula, medial prefrontal cortex, and the rest of the brain. Furthermore, we explored whether potential functional connectivity differences were correlated with clinical characteristics including disease duration, pain intensity, and different psychosocial factors (pain catastrophizing, fear of pain, functional disability, anxiety, and depression).

RESULTS

Our findings revealed that patients with EAP demonstrated significantly decreased connectivity between the right anterior insula and two clusters: one in the right cerebellum, and one in the left middle frontal gyrus compared to controls. Additionally, functional connectivity between the right anterior insula and the right cerebellum was positively associated with pain intensity levels. In patients with EAP, brain changes were also correlated with state anxiety and fear of pain.

CONCLUSIONS

Our results are relevant not only for understanding the brain characteristics underlying EAP at a younger age, but also in enhancing future pain treatment efforts by supporting the involvement of the central nervous system in endometriosis.

Cutting the cord? Parenting emerging adults with chronic pain

The role of parent factors, such as distress and protective behaviors, on pain and functional outcomes of emerging adults living with chronic pain has been largely unexplored. The effects of helicopter parenting and developmental changes occurring during this transition period between adolescence and adulthood (commonly defined as the ages between 18 and 30 years) may exacerbate the pain experience and have the potential to influence chronic pain management. Clinical practice, with an additional focus on supporting the parent(s), may aid in meeting the needs of this population. In this paper, we review the available literature on (a) the socio-cultural shift in parenting over the past decade with a focus on helicopter parenting; (b) the impact of this parenting style on the pain experience and outcomes of emerging adults living with chronic pain; (c) provide recommendations for chronic pain management with a focus on the parent-emerging adult dyad; and (d) conclude with future research recommendations. This narrative review is the first to consider the impacts and outcomes of helicopter parenting on emerging adults with chronic pain.

Association of Preexisting Mental Health Conditions With Increased Initial Symptom Count and Severity Score on SCAT5 When Assessing Concussion

Background:

Mental health conditions, such as depression, anxiety, and learning disabilities, are associated with symptoms that can overlap with those seen in persons with concussion. While concussion screening tools such as the Sport Concussion Assessment Tool–5th Edition (SCAT5) quantify the number of symptoms and symptom severity, it is not known whether these outcomes differ among individuals with concurrent mental health conditions compared with those without them.

Purpose:

To determine whether, during initial concussion assessment, individuals with a self-reported mental health condition have a significantly different number of self-reported concussion symptoms or symptom severity compared with those without a self-reported mental health condition (controls).

Study Design:

Cohort study; Level of evidence, 3.

Methods:

A retrospective chart review was performed on consecutive patients aged ≥13 years who underwent post-concussion assessment at the Fowler Kennedy Sport Medicine Clinic between May 2018 and March 2020 (N = 765). Most participants did not self-report a mental health condition (n = 606; 79.2%). Participants with a self-reported mental health condition (n = 159) were classified as having a learning disability (n = 14; 8.8%), anxiety (n = 62; 39.0%), depression (n = 20; 12.6%), or multiple conditions (≥2 conditions: n = 63; 39.6%). Each participant with a mental health condition was matched with 2 control participants (overall pool, n = 318) based on age, sex, student status, and sport-related risk. Mann-Whitney U tests were used to determine the statistical significance of differences between each subgroup and their matched controls for the self-reported number of concussion symptoms and symptom severity as measured using the SCAT5.

Results:

The anxiety and multiple-conditions subgroups had a significantly greater number of reported symptoms than their corresponding control subgroups (median, 17 vs 15 [P = .004] and 18 vs 14.5 [P < .001], respectively). Additionally, the SCAT5 symptom severity score was significantly greater in the anxiety and multiple-conditions subgroups than their corresponding controls (median, 49 vs 34.5 [P = .018] and 62 vs 32 [P < .001], respectively).

Conclusion:

During initial concussion assessment, both the number of concussion-related symptoms and the symptom severity were greater in study participants with anxiety and multiple mental health conditions than participants without these conditions.

The concept of pain inventory for children: The reliability and validity study of the Turkish version

BACKGROUND AND PURPOSE

Pain experiences in childhood are very likely to be reflected in adulthood. The early evaluation of the concept of pain in children may eventually lead to. better patient outcomes in the future. Therefore, we aimed to culturally and developmentally adapt the Concept of Pain Inventory for Children (COPI) for Turkish children.

METHODS

This descriptive, correlational study was conducted with 239 post-operative children aged 8-12 years between June and December 2021. The research adhered to COSMIN guidelines. The data were collected using a descriptive information form and the COPI. Factor analysis, Cronbach's alpha, and item-total score analysis were used for the data analysis.

RESULTS

The resulting unidimensional scale consists of 12 items in Turkish. The scale explained 65% of the total variance. The exploratory factor analysis showed that the factor loadings of items ranged from 0.64 to 0.91. The confirmatory factor analysis showed that the factor loadings of items ranged from 0.66 to 0.92. Goodness of fit indexes were found to be as follows: Normed Fit Index >0.90; Incremental Fit Index >0.90; Comparative Fit Index >0.90; and the Root Mean Square Error of Approximation <0.08. The total Cronbach's alpha coefficient of the scale was 0.78 (reliable).

CONCLUSIONS

The 12-item Turkish translation of the COPI was deemed valid and reliable in 8-12-year-old children in a post-operative setting.

PRACTICE IMPLICATIONS

Evaluation of children's pain concepts during childhood may contribute to the identification of conceptual gaps for pain science education.

The Influence of Adverse Childhood Experiences in Pain Management: Mechanisms, Processes, and Trauma-Informed Care

Adverse childhood experiences (ACEs) increase the likelihood of reduced physical and psychological health in adulthood. Though understanding and psychological management of traumatic experiences is growing, the empirical exploration of ACEs and physical clinical outcomes remains under-represented and under-explored. This topical review aimed to highlight the role of ACEs in the experience of chronic pain, pain management services and clinical decision making by: (1) providing an overview of the relationship between ACEs and chronic pain; (2) identifying biopsychosocial mechanisms through which ACEs may increase risk of persistent pain; (3) highlighting the impact of ACEs on patient adherence and completion of pain management treatment; and (4) providing practical clinical implications for pain management. Review findings demonstrated that in chronic pain, ACEs are associated with increased pain complications, pain catastrophizing and depression and the combination of these factors further heightens the risk of early treatment attrition. The pervasive detrimental impacts of the COVID-19 pandemic on ACEs and their cyclical effects on pain are discussed in the context of psychological decline during long treatment waitlists. The review highlights how people with pain can be further supported in pain services by maintaining trauma-informed practices and acknowledging the impact of ACEs on chronic pain and detrimental health outcomes. Clinicians who are ACE-informed have the potential to minimize the negative influence of ACEs on treatment outcomes, ultimately optimizing the impact of pain management services.

Blended-Learning Pain Neuroscience Education and Exercise in High School Students With Chronic Neck Pain: A Randomized Controlled Trial

OBJECTIVE

Pain neuroscience education (PNE) and exercise have emerged as potential interventions in adolescents with chronic pain; however, very few studies have explored their effectiveness. Blended-learning approaches combining face-to-face and online educational sessions have also emerged as facilitating methods of health education. This study aimed to compare the effectiveness of exercises and PNE versus exercise alone in adolescents with chronic neck pain (NP).

METHODS

A randomized controlled trial with 6-month follow-up was conducted in 2 high schools. Over 8 weeks, a total of 127 adolescents with chronic NP were randomly allocated to either (1) perform functional and region-specific exercises, including generalized neuromuscular control, endurance, and strength exercises, as well as exercises targeting the deep neck flexor and extensor muscles and scapular stabilizer muscles; or (2) perform the same exercise-based intervention plus PNE. Pain intensity (primary outcome), disability, sleep, catastrophizing, fear of movement, self-efficacy, and knowledge of pain neuroscience were assessed at baseline, postintervention, and 6-month follow-up. Neck and scapular muscle endurance and pressure pain thresholds were assessed at baseline and postintervention. Patient's Global Impression of Change was assessed postintervention and at 6-month follow-up.

RESULTS

There was a significant decrease in pain intensity from baseline to postintervention and from baseline to follow-up in both groups, but there were no between-group differences or interactions between time and groups. These results were similar for the secondary outcomes, except for knowledge of pain neuroscience, for which a significant group and time interaction was found.

CONCLUSION

Exercise and exercise plus PNE were similarly effective in treating adolescents with chronic NP, and the results were maintained for up to 6 months. Further studies are needed to explore the effect of these interventions for longer follow-ups.

Comparing opioid types in the persistence of opioid use following surgical admission: a study protocol for a retrospective observational linkage study comparing tapentadol and oxycodone in Australia

INTRODUCTION

Each year, an estimated two million Australians commence opioids, with 50 000 developing longer-term (persistent) opioid use. An estimated 3%-10% of opioid-naïve patients prescribed opioids following surgery develop persistent opioid use. This study will compare rates of persistent opioid use between two commonly used postoperative opioids, oxycodone and tapentadol, to understand if initial postoperative opioid type is important in determining longer-term outcomes.

METHODS AND ANALYSIS

A retrospective data linkage study that analyses administrative data from hospital and community pharmacies. Data will be obtained from at least four pharmacies that service large hospitals with comparable supplies of oxycodone and tapentadol. The study will include at least 6000 patients who have been dispensed a supply of oxycodone or tapentadol to take home following their discharge from a surgical ward. The primary outcome measure will be persistent opioid use at 3 months postdischarge for opioid naïve people who receive either immediate release tapentadol or immediate release oxycodone. Hierarchical logistic regression models will be used to predict persistent opioid use, controlling for covariates including comorbidities.

ETHICS AND DISSEMINATION

Ethics approval has been obtained through the Monash University Human Research Ethics Committee (29977). We will present project findings in a peer-reviewed journal article, in accordance with the REporting of studies Conducted using Observational Routinely-collected health Data statement.

Impact of sex, sleep, symptoms of central sensitization and psychosocial factors in adolescents with chronic musculoskeletal pain-an exploratory study

OBJECTIVE

This study aimed to explore and compare the association between psychosocial factors, sleep, central sensitization, and chronic neck, back, limbs, and multiregional pain and disability.

METHODS

1730 adolescents responded to an online questionnaire containing: sociodemographic data, Nordic Musculoskeletal Questionnaire, International Physical Activity Questionnaire, Functional Disability Inventory, Depression, Anxiety and Stress Scale, Basic Scale on Insomnia Complaints and Quality of Sleep, Pain Catastrophizing Scale, Tampa Scale of Kinesiophobia, Child Self-Efficacy Scale and Central Sensitization Inventory. Univariable and multivariable regression analysis was used to assess the associations between these variables and pain and disability.

RESULTS

Groups were categorized into neck (n = 54), back (n = 80), upper limb (n = 52), lower limb (n = 109) and multiregional (n = 1140) pain. Multivariable analysis showed that symptoms of central sensitization increased odds of neck, back, and multiregional pain; depression, anxiety and stress, and physical activity increased odds of multiregional pain; and fear of movement increased odds of lower limb pain. Female gender increased the odds of pain in all groups, except in the lower limb group. Depression, anxiety, and stress also remained associated with disability in neck, back, upper limb, and multiregional pain; poorer sleep remained associated with disability in neck, upper limb, and multiregional pain; catastrophizing remained associated with back, and multiregional pain; and fear of movement and symptoms of central sensitization were only associated with disability in multiregional pain.

CONCLUSIONS

There are similar but also different variables associated with the presence of pain and disability in the neck, back, limbs, and multiregional pain.

Amygdala functional connectivity mediates the association between catastrophizing and threat-safety learning in youth with chronic pain

ABSTRACT

There is a need to identify brain connectivity alterations predictive of transdiagnostic processes that may confer vulnerability for affective symptomology. Here, we tested whether amygdala resting-state functional connectivity (rsFC) mediated the relationship between catastrophizing (negative threat appraisals and predicting poorer functioning) and altered threat-safety discrimination learning (critical to flexibly adapt to new and changing environments) in adolescents with persistent pain. We examined amygdala rsFC in 46 youth with chronic pain and 29 healthy peers (age M = 15.8, SD = 2.9; 64 females) and its relationship with catastrophizing and threat-safety learning. We used a developmentally appropriate threat-safety learning paradigm and performed amygdala seed-based rsFC and whole-brain mediation analyses. Patients exhibited enhanced connectivity between the left amygdala and right supramarginal gyrus (SMG) (cluster-level P-FDR < 0.05), whereas right amygdala rsFC showed no group differences. Only in patients, elevated catastrophizing was associated with facilitated threat-safety learning (CS+>CS-; rp = 0.49, P = 0.001). Furthermore, in patients, elevated catastrophizing was associated with reduced left amygdala connectivity with SMG / parietal operculum, and increased left amygdala connectivity with hippocampus, dorsal striatum, paracingulate, and motor regions (P < 0.001). In addition, blunted left amygdala rsFC with right SMG/parietal operculum mediated the association between catastrophizing and threat-safety learning (P < 0.001). To conclude, rsFC between the left amygdala (a core emotion hub) and inferior parietal lobe (involved in appraisal and integration of bodily signals and attentional reorienting) explains associations between daily-life relevant catastrophizing and threat-safety learning. Findings provide a putative model for understanding pathophysiology involved in core psychological processes that cut across diagnoses, including disabling pain, and are relevant for their etiology.

Psychological Traits of Patients With Depression Comorbid With Chronic Pain: Are Complaint and Competitive Tendency Related to Pain?

BACKGROUND

Modern-Type Depression (MTD) is a category of depression that has been studied mainly in Japan; however, no study has attempted to determine its relation to chronic pain.

AIM

To determine possible associations between psychological traits related to MTD and the chronic pain of patients at psychiatric clinics.

METHOD

Two hundred and twenty-one first time patients who visited the psychiatric clinic at a Japanese university medical center or an associated clinic were enrolled. The Hamilton Depression Rating Scale was used to measure depressive symptoms. The 22-item Tarumi's Modern-Type Depression Trait Scale (TACS-22), Achievement Motive, and 20-item Toronto Alexithymia Scale were used to assess psychological traits related to depression and chronic pain. The clinical diagnosis of each patient was confirmed by use of the Structured Clinical Interview for DSM-IV Axis I Disorders, administered by experienced specialists. The medians of the psychological traits identified were compared between patients with or without chronic pain. Analysis was also done of patients with Major Depressive Disorder (MDD).

RESULT

Of the 221 patients, 139 had chronic pain. Patients with chronic pain had more severe depressive symptoms, Alexithymia, and high scores for the complaint trait of MTD. Seventy-three of the 221 patients met the criteria for MDD (53 had chronic pain). Patients with MDD comorbid with chronic pain had a higher competitive achievement score, severe depression, and difficulty identifying feelings.

CONCLUSION

Complaint and competitive traits were shown to be related to chronic pain in psychiatric settings. Further study will allow us to design multidimensional approach for patients suffering from depression.

The Association Between Psychological Symptoms and Self-Reported Temporomandibular Disorders Pain Symptoms in Children and Adolescents

Background: Several studies have reported an association between temporomandibular disorder pain (TMD-P) and emotional disorders in children and adolescents. However, no studies have reported if self-reported TMD-P in Saudi Arabia is associated with psychosocial symptoms. Therefore, the current study aimed to evaluate the association between self-reported TMD-P with depression, anxiety and somatic problems in children and adolescents in Saudi Arabia. The hypothesis was that there is an association between self-reported TMD-P and psychological symptoms among children and adolescents.

Materials and Methods: The included participants were randomly selected boys and girls aged between 10 and 18 years, with a mean (SD) age of 14.0 (2.3) years. Out of 633 children and adolescents that were invited to participate, 509 voluntarily agreed to participate, and 466 completed all questionnaires. The questionnaires included items retrieved from the Youth Self Report (YSR) and Axis II of the Research Diagnostic Criteria for TMD (RDC/TMD) besides demographic data, medical history, and presence of oral parafunctions. To assess the presence of self-reported TMD-Pain, each participant was verbally asked two validated questions regarding the presence of TMD-P and dysfunction (2Q-TMD).

Results: Self-reported TMD-P in children and adolescents was significantly associated with anxiety, depression, somatic symptoms, and social problems (P < 0.0001). Further, the frequencies of anxiety, depression, and somatic disorders were more evident among children and adolescents who suffered from TMD-P (P < 0.0001). The odds of reporting TMD-P in children and adolescents was 1.4 times for border line and clinical diagnosis scores for anxiety and withdrawal depression domains, and 2.6 times for the somatic symptoms' domains. However, in the multiple regression model after controlling for possible confounders, only somatic symptoms and social scores were significant. Moreover, self-reported TMD-P was twice as prevalent among girls compared to boys.

Conclusion: This study reports a significant association between psychosocial burden and presence of self-reported TMD-Pain, with a stronger impact on girls than boys. There were significantly higher number of participants with self-reported TMD-P reporting a poor oral and general health. In addition, self-reported TMD-P was higher among those with borderline and clinically diagnosed anxiety/depression scores. Based on this finding, the current study supports that an early approach and recognition of children and adolescents with anxiety, depression, somatic symptoms, and TMD problems. This could result in a lesser burden for these children and adolescents both in regard to pain and psychosocial implications with increased quality of life.

Clinical Utility of CAT Administered PROMIS Measures to Track Change for Pediatric Chronic Pain

Patient Reported Outcomes (PROs) are utilized in clinical registries and trials, necessitating development of benchmarks to enhance interpretability. This study aimed to 1) examine if PROMIS measures administered via computer adaptive testing (CAT) were responsive to change, and 2) highlight one method of assessing clinically significant change for youth seen in a tertiary pain clinic. Clinically significant change was achieved if patients had significantly reliable pre-to-post-changes greater than Reliable Change Index (RCI) value and reported decreased symptoms by at least one severity level (e.g., moderate to mild). Participants were 328 youth (8-17 years old) seen in a tertiary pediatric pain management clinic. Small to moderate effect sizes were noted across PROMIS measures (except Peer Relations). Reliable magnitudes of change were estimated for this sample as approximately 6 point reduction for Pain Interference and Mobility, 9 for Fatigue, and 11 for Anxiety and Depression. Depending on the measure, 10 to 24% were categorized as improved, 3 to 6% as deteriorated, and 68 to 81% were either not clinically elevated at baseline or remained unchanged at 3 months. Overall, PROMIS CAT measures demonstrated responsiveness to change over time. Estimation of clinically significant change offers preliminary yet rigorous benchmarks for evaluating treatment response and sets the stage for understanding treatment effects. PERSPECTIVE: This study assesses responsiveness of CAT administered PROMIS measures and highlights one methodological approach of presenting clinical significance for assessing treatment outcomes in pediatric chronic pain. These benchmarks will allow clinicians and researchers to evaluate treatment response utilizing PROs while allowing for a deeper understanding of treatment effects.

Diagnostic criteria for temporomandibular disorders (DC/TMD) in children and adolescents: an international Delphi study-Part 2-Development of Axis II

BACKGROUND

Unlike the psychosocial assessment established for adults in the diagnostic criteria for temporomandibular disorders (DC/TMD), a standardized psychosocial assessment for children and adolescents with TMD complaints has not yet been established.

OBJECTIVES

To develop a new standardized instrument set to assess the psychosocial functioning in children and adolescents by adapting the psychosocial status and pain-related disability (Axis II) of the adult DC/TMD and by including new instruments.

METHODS

A modified Delphi method was used to survey 23 international TMD experts and four international experts in pain-related psychological factors for consensus regarding assessment tools for psychosocial functioning and pain-related disability in children and adolescents. The TMD experts reviewed 29 Axis II statements at round 1, 13 at round 2, and 2 at round 3. Agreement was set at 80% for first-round consensus level and 70% for each of the second and third rounds. The psychological experts completed a complementary Delphi survey to reach a consensus on tools to use to assess more complex psychological domains in children and adolescents. For the psychological experts, the first round included 10 open-ended questions on preferred screening tools for depression, anxiety, catastrophizing, sleep problems, and stress in children (ages 6-9 years old) and adolescents (ages 10-19 years old) as well as on other domains suggested for investigation. In the second round, the psychological experts received a 9-item questionnaire to prioritize the suggested instruments from most to least recommended.

RESULTS

The TMD experts, after three Delphi rounds, reached consensus on the changes of DC/TMD to create a form to evaluate Axis II in children and adolescents with TMD complaints. The psychological experts added tools to assess depression and anxiety, sleep disorders, catastrophizing, stress, and resilience.

CONCLUSION

Through international expert consensus, this study adapted Axis II of the adult DC/TMD to assess psychosocial functioning and pain-related disability in children and adolescents. The adapted Axis II protocols will be validated in the target populations.

Beliefs About Worry and Pain Amongst Adolescents With and Without Chronic Pain

OBJECTIVE

To explore beliefs about worries, beliefs about pain, and worries about pain held by adolescents with and without chronic pain.

METHODS

Adolescents with and without chronic pain aged 14-19 completed an online survey with free text questions about pain and worry. We collected demographics and used the Penn State Worry Questionnaire and Pain Catastrophizing Scale for Children to contextualize the qualitative data, which was analyzed with reflexive thematic analysis.

RESULTS

Eighty-one participants completed the survey, 36 with chronic pain and 45 without (mean age: 16.73). Compared to adolescents without chronic pain, adolescents living with chronic pain reported significantly higher general worry and pain catastrophizing. Thematic analysis generated two themes, "Worry changes perceptions of selfhood" and "Pain changes perceptions of selfhood." Each theme comprised two sub-themes showing how current and future identity trajectories were distorted by worry and pain. The theme "Pain changes perceptions of selfhood" also included a third sub-theme: "Pain impedes future working choices." Worry content as well as process was problematic in all adolescents. Adolescents experiencing chronic pain had specific, additional worries that pain reduces future career progression. These worries appeared highly salient and challenging.

CONCLUSIONS

Adolescents may need greater support in recognizing worry as part of normative development. Adolescents in pain may benefit from specific support identifying and reducing how pain-related worries interact with their futures and careers, and from school-based and vocational interventions to reduce the realistic risks they face negotiating modern labor markets.

Targeting Coping to Improve Surgical Outcomes in Pediatric Patients With Median Arcuate Ligament Syndrome: Feasibility Study

Background: Median arcuate ligament syndrome (MALS) is a vascular compression syndrome leading to postprandial epigastric pain, nausea, and weight loss; it can be treated surgically. While most patients report improved quality of life following surgical intervention, 30% continue to experience chronic abdominal pain. Pre-surgical diagnoses of depression and/or anxiety have been found to significantly predict post-surgical: quality of life, highest experience of pain, anxiety, and parent- and self-reported coping strategies. As such, increasing the coping strategies of pediatric patients with MALS may impact their post-surgical outcomes. The purpose of the current study was to: (1) implement a pre-operative cognitive behavioral therapy protocol with a focus on psychoeducation and coping strategies; and (2) determine feasibility of a pre-surgical intervention for this population. Method: Children (<18 years of age) with a diagnosis of MALS who were eligible for surgical intervention were invited to participate in a 7-week in-person or video-based pre-surgical cognitive behavioral therapy intervention. Psychiatric comorbidities were assessed at baseline and post-surgery; patient-reported distress, pain interference and intensity, health-related quality of life, and health status were assessed at four time points (baseline, week 4, week 7, and post-surgery). Descriptive analyses were used to characterize the sample, assess feasibility outcomes (i.e., attrition rates), and explore symptom-based outcomes across time. Results: Twelve pediatric patients (M age = 15.2 ± 1.7; 91.7% female) and their parents (91.7% mothers) participated. Feasibility metrics based on protocol completion were exceeded for engagement at the stages of consent (68.4% vs. goal of ≥50%), treatment initiation (92.3% vs. 85%), and treatment completion (84.6% vs. 75%). Out of the 12 participants, nine (75%) met criteria for at least one comorbid psychiatric diagnosis at baseline and nine (75%) elected to undergo MALS surgery after completing the intervention. Conclusion: The intervention implementation was feasible, despite chronic pain symptoms experienced by the sample, a high prevalence of psychiatric diagnoses, and an international pandemic, suggesting that it would be beneficial to further evaluate the efficacy of the intervention. Future research should include stakeholder input in the design, deployment, and evaluation of a pilot efficacy trial of pre-surgical cognitive behavioral therapy for pediatric patients with MALS.

Predictors of pain persistence and disability in high-school students with chronic neck pain at 6-month follow-up

BACKGROUND

Neck pain tends to persist for periods of 1 to 4 years of follow-up in adolescents, and a high percentage of them report disability. However, studies assessing the factors associated with persistent neck pain and disability in this age group are scarce. This study aimed to explore the association between psychosocial factors, sleep, and symptoms of central sensitization at baseline and the persistence of neck pain and disability at 6-month follow-up.

METHODS

A total of 710 adolescents with chronic neck pain were assessed at baseline with an online questionnaire that collected information on sociodemographic data, presence of musculoskeletal pain, pain intensity, physical activity, functional disability, depression, anxiety, stress, quality of sleep, catastrophizing, kinesiophobia, self-efficacy, and symptoms of central sensitization. At 6-month follow-up, adolescents were reassessed for disability and pain intensity and categorized as recovered or reporting persistent neck pain.

RESULTS

Of the 710 participants with neck pain at baseline, 334 were classified as having persistent neck pain and 375 adolescents as being recovered at 6-month follow-up. Multivariable analysis showed that female gender (OR 1.47; p = 0.04) and symptoms of central sensitization (OR 1.02; p = 0.001) at baseline were positively associated with the persistence of neck pain at 6-month follow-up. Similarly, higher levels of disability (β = 0.41; p < 0.001) and symptoms of central sensitization (β = 0.28; p < 0.001) at the baseline were positively associated with disability.

CONCLUSIONS

Symptoms of central sensitization and disability at baseline should be considered in the assessment and design of interventions for adolescents with chronic neck pain as an attempt to minimize its future impact on pain persistence and disability.

Revisions to the IASP definition of pain-What does this mean for children?

The complexity of the phenomenon of pain defies a simple and straightforward definition. Acute, chronic, nociplastic and neuropathic pain account for multiple pathologic mechanisms and forms of expression. Pain varies widely in intensity, duration and nature, often complicating description for those who are experiencing the pain and/ or those who are observing it. Assessment of pain in children can be challenging, especially in those who may be incapable of self-report report due to development immaturity or disability. In these children the responsibility of assessing pain often falls to the professional or lay care provider, whose knowledge, expertise and beliefs influence their judgements. The experience of pain includes not only the physiologic and behavioural indicators most frequently included in pain assessment measures but also encompasses the social and cognitive components that often go unrecognized. The 1979 IASP definition of pain has been praised for its brevity, simplicity and attention to the multidimensional nature of the phenomenon. It has also been criticized for ignoring mind-body interactions, disempowering and neglecting vulnerable populations, paying little attention to ethical dimensions, and excluding cognitive and social factors that are integral to the experience of pain. After four decades, the 1979 definition of pain and the accompanying notes were evaluated and revised by a 14-member IASP presidential task force with representation from basic and clinical research, geographical location and populations served (Pain, 2020, 161, 1976). These revisions resulted in decreasing the emphasis of pain associated with tissue damage in the definition, and, by removing the word 'described', allowing those who were nonverbal to be assessed using other validated pain indicators. Important revisions were also made to the Notes. The revisions that are most relevant for pain in children are discussed.

Chronic non-cancer pain in adolescents: a narrative review

Introduction

Chronic pain is defined as a pain lasting more than 3–6 months. It is estimated that 25% of the pediatric population may experience some kind of pain in this context. Adolescence, corresponding to a particular period of development, seems to present the ideal territory for the appearance of maladaptive mechanisms that can trigger episodes of persistent or recurrent pain.

Methods

A narrative review, in the PubMed/Medline database, in order to synthetize the available evidence in the approach to chronic pain in adolescents, highlighting its etiology, pathophysiology, diagnosis, and treatment.

Results

Pain is seen as a result from the interaction of biological, psychological, individual, social, and environmental factors. Headache, abdominal pain, and musculoskeletal pain are frequent causes of chronic pain in adolescents. Pain not only has implications on adolescents, but also on family, society, and how they interact. It has implications on daily activities, physical capacity, school performance, and sleep, and is associated with psychiatric comorbidities, such as anxiety and depression. The therapeutic approach of pain must be multimodal and multidisciplinary, involving adolescents, their families, and environment, using pharmacological and non-pharmacological strategies.

Discussion and conclusion

The acknowledgment, prevention, diagnosis, and treatment of chronic pain in adolescent patients seem not to be ideal. The development of evidence-based forms of treatment, and the training of health professionals at all levels of care are essential for the diagnosis, treatment, and early referral of these patients.

Phenotyping peripheral neuropathic pain in male and female adolescents: pain descriptors, somatosensory profiles, conditioned pain modulation, and child-parent reported disability

ABSTRACT

Neuropathic pain (NeuP) can be difficult to diagnose and manage in children. Data regarding prevalence and sex-dependent differences are limited, and more detailed phenotyping is needed. This observational cohort study recruited adolescents (10-17 years) with NeuP or complex regional pain syndrome (CRPS). After pain history and NeuP questionnaires, quantitative sensory testing was performed. Individual z-score plots were calculated with body-region control measures and matched to mechanism-related sensory profiles (sensory loss, thermal hyperalgesia, and mechanical hyperalgesia). Conditioned pain modulation was assessed with pressure pain threshold and a contralateral cold conditioning stimulus, and meaningful conditioned pain modulation defined as twice the standard error of measurement. Patients and parents completed validated questionnaires for child quality of life (QoL), pain catastrophizing, and self-reported anxiety/depression. Males (n = 23) and females (n = 43) with NeuP (n = 52) or CRPS (n = 14) reported moderate-severe pain with neuropathic sensory descriptors. Mixed patterns of sensory gain/loss at pain sites were not sex-dependent. Thermal hyperalgesia was common in both NeuP and CRPS, whereas sensory loss occurred only with NeuP and in a smaller proportion than adult cohorts. Conditioned pain modulation was inhibitory in 54%, facilitatory in 14%, and nonresponders had variable cold conditioning sensitivity. Males and females reported marked impairment of QoL, increased emotional distress, and pain catastrophising. Child-parent QoL scores correlated, but catastrophizing scores were discordant when parents or adolescents reported higher anxiety/depression. NeuP in adolescents is associated with significant pain, physical impairment, and psychosocial impairment. Quantifying alterations in somatosensory profiles, descending modulation, child and parent psychological function will inform individualized therapy and stratification for future clinical trials.

Psychological aspects of pain prevention

How to prevent the onset, maintenance, or exacerbation of pain is a major focus of clinical pain science. Pain prevention can be distinctly organised into primary, secondary, and tertiary prevention. Primary prevention describes avoiding hurt or pain, secondary prevention describes reducing pain when pain is unavoidable, and tertiary prevention describes preventing or reducing ongoing negative consequences such as high functional disability or distress due to chronic pain. Each poses separate challenges where unique psychological factors will play a role. In this short review article, we highlight psychological factors important to primary, secondary, and tertiary prevention and provide direction for the field. We present 2 case studies on secondary prevention in children and adolescents and tertiary prevention in adults with chronic pain. Finally, we provide research directions for progression in this field, highlighting the importance of clear theoretical direction, the identification of risk factors for those most likely to develop pain, and the importance of treatment.

Systematic Review: Psychosocial Correlates of Pain in Pediatric Inflammatory Bowel Disease

BACKGROUND

Pain is a common symptom in pediatric inflammatory bowel disease (IBD) and is associated with poor health outcomes, yet additional knowledge about the psychosocial correlates of pain is needed to optimize clinical care. The purpose of this study is to systematically review the psychosocial factors associated with pain and pain impact in youth diagnosed with IBD within a developmentally informed framework.

METHODS

Manual and electronic searches yielded 2641 references. Two authors conducted screening (98% agreement), and data extraction was performed in duplicate. Average study quality was rated using the National Institutes of Health Quality Assessment Tool.

RESULTS

Ten studies (N = 763 patients; N = 563 Crohn disease, N = 200 ulcerative/ indeterminate colitis) met the inclusion criteria. Findings showed consistent evidence that higher levels of child depression symptoms and child pain catastrophizing were associated with significantly greater pain and pain impact (magnitude of association ranged from small to large across studies). Greater pain and pain impact were also associated with higher levels of child anxiety symptoms, child pain threat, child pain worry, and parent pain catastrophizing. Within the included studies, female sex and disease severity were both significantly associated with pain and pain impact. Study quality was moderate on average.

CONCLUSIONS

There is evidence that child psychosocial factors are associated with pain and pain impact in pediatric IBD; more studies are needed to examine parent- and family-level psychosocial factors. Youth with IBD should be routinely screened for pain severity, pain impact, and psychosocial risk factors such as anxiety/depression.

Neuropsychiatric Symptoms in Pediatric Chronic Pain and Outcome of Acceptance and Commitment Therapy

Considerable heterogeneity among pediatric chronic pain patients may at least partially explain the variability seen in the response to behavioral therapies. The current study tested whether autistic traits and attention-deficit/hyperactivity disorder (ADHD) symptoms in a clinical sample of children and adolescents with chronic pain are associated with socioemotional and functional impairments and response to acceptance and commitment therapy (ACT) treatment, which has increased psychological flexibility as its core target for coping with pain and pain-related distress. Children and adolescents aged 8–18 years (N = 47) were recruited. Patients and their parents completed questionnaires pre- and post-ACT of 17 sessions. Correlational analyses and mixed-effects models were used to assess the role of autistic traits and ADHD symptoms in pretreatment functioning and ACT-treatment response. Outcome variables were degree to which pain interfered with daily activities (i.e., pain interference, sleep, and physical and school functioning), socioemotional functioning (i.e., depressive symptoms, emotional, and social functioning), psychological inflexibility, and pain intensity. Autistic traits and ADHD symptoms, pain frequency, and pain duration were measured at pretreatment only. Higher autistic traits were associated with greater pain interference, higher depression, and greater psychological inflexibility. Higher ADHD symptomatology was associated with greater pretreatment pain interference, lower emotional functioning, greater depression, and longer duration of pain. Across patients, all outcome variables, except for sleep disturbances and school functioning, significantly improved from pre- to post-ACT. Higher autistic traits were associated with greater pre- to post-ACT improvements in emotional functioning and sleep disturbance and non-significant improvements in pain interference. ADHD symptomatology was not associated with treatment outcome. The current results showed that neuropsychiatric symptoms in pediatric chronic pain patients are associated with lower functioning, particularly pain interfering with daily life and lower socioemotional functioning. The results suggest that not only pediatric chronic pain patients low in neuropsychiatric symptoms may benefit from ACT, but also those high in autism traits and ADHD symptoms. With the present results in mind, pediatric chronic pain patients higher in autistic traits may actually derive extra benefit from ACT. Future research could assess whether increased psychological flexibility, the core focus of ACT, enabled those higher in autism traits to cope relatively better with pain-related distress and thus to gain more from the treatment, as compared to those lower in autism traits. Moreover, to address specific effects of ACT, inclusion of an appropriate control group is key.

Are chronic musculoskeletal pain and generalized joint hypermobility: disabling contributors to physical functioning?

BACKGROUND

Chronic musculoskeletal pain (CMP), Generalized Joint Hypermobility (GJH) and pain-related fear have influence on physical functioning in adolescents.

AIM

To evaluate differences in physical functioning between adolescents with CMP, GJH or the combination of both, and in addition evaluate the potential contribution of pain-related fear.

DESIGN

Observational, cross-sectional design.

SETTING

The adolescents with CMP were recruited by a physician in rehabilitation medicine and measured in the university outpatient rehabilitation clinic (Adelante/Maastricht University Medical Center+, the Netherlands). The adolescents without CMP were recruited in the Southern area of the Netherlands and measured in the university outpatient rehabilitation clinic (Adelante/Maastricht University Medical Center+, the Netherlands).

POPULATION

Four subgroups of adolescents were included; 21 adolescents with CMP without GJH, 9 adolescents with CMP and GJH, 51 adolescents without CMP without GJH, and 11 adolescents without CMP with GJH.

METHODS

Outcome measures were muscle strength and endurance, motor performance, physical activity level, and pain-related fear were measured. Hierarchical regression analyses were used to study differences in physical functioning and the contribution of pain-related fear in adolescents with/without CMP as well as with/without GJH.

RESULTS

Adolescents with CMP had decreased muscle strength (p=0.01), endurance (p=0.02) and lower motor performance (p<0.01) compared to adolescents without CMP. Higher levels of pain-related fear were related to decreased muscle strength (p=0.01), endurance (p<0.01) and motor performance (p<0.01). No differences in physical functioning and pain-related fear between hypermobile and non-hypermobile adolescents with CMP were found.

CONCLUSIONS

Adolescents with CMP had decreased muscle strength and motor performance associated with increased levels of pain-related fear compared to adolescents without CMP. The association of being hypermobile with physical functioning is not more pronounced in adolescents with CMP.

CLINICAL REHABILITATION IMPACT

No differences were found in physical functioning and pain-related fear between hypermobile adolescents with CMP compared to nonhypermobile adolescents with CMP. Future rehabilitation treatment in hypermobile adolescents with CMP should also focus on psychological components, such as pain-related fear.
