Youth With Chronic Pain and a History of Adverse Childhood Experiences in the Context of Multidisciplinary Pain Rehabilitation

Gender Diversity Among Youth Attending an Intensive Interdisciplinary Pain Treatment Program

Transgender and gender diverse (TGD) youth with chronic pain may be at unique risk for psychological distress and associated functional impairment, yet research on the intersection of chronic pain and gender identity is lacking. In a retrospective chart review of 491 participants admitted to a pediatric intensive interdisciplinary pain treatment (IIPT) program in the midwestern United States over an approximately 4-year period, 6.11% were TGD. TGD participants who completed the IIPT program reported significant and large improvements in anxiety, depression, pain catastrophizing, and functional ability. At baseline, TGD participants presented as more emotionally distressed and functionally impaired compared to age-matched, cisgender peers. When accounting for baseline scores, TGD participants who completed the IIPT program reported similar scores to cisgender peers at discharge, yet TGD youth were significantly less likely than cisgender peers to complete the IIPT program. Future directions and implications for clinical practice are discussed.

Intensive interdisciplinary pain treatment for children and adolescents with chronic noncancer pain: a preregistered systematic review and individual patient data meta-analysis

ABSTRACT

Chronic noncancer pain in children and adolescents can be impairing and results in substantial health care costs. Intensive interdisciplinary pain treatment (IIPT), an inpatient or day hospital treatment delivered by a team of 3 or more health professionals, may be an effective intervention for these children and adolescents. Based on previous reviews and meta-analyses, we updated findings regarding the description of available treatments and estimated the effectiveness of IIPT, overcoming methodological shortcomings of previous work by requesting and analyzing individual participant data. On June 26, 2021, we searched 5 literature databases (PubMed, PsycINFO, Web of Science, Cochrane Library, and PubPsych) for studies examining the effectiveness of IIPT. Included studies used a pre-post design, assessed patients younger than 22 years, and presented their results in English, German, French, or Spanish. We used standard methodological procedures expected by Cochrane to pool treatment effects and assess risk of bias. We identified 13 different treatment sites with similar treatment inclusion criteria and treatment components, but the descriptions of those treatments varied widely. Regarding treatment effectiveness, IIPT may result in large improvements in the mean pain intensity ( g = -1.28), disability ( g = -1.91), and number of missed school days at the 12-month follow-up ( g = -0.99), as well as moderate improvements in anxiety ( g = -0.77) and depression ( g = -0.76). The certainty of the evidence, however, was graded from very low to low. We recommend that future researchers use more scientific rigor to increase the certainty of the evidence for IIPT and standardize treatment outcomes for children and adolescents with chronic pain.

Will This Treatment Help My Child?: How Parent/Caregiver Treatment Expectations Relate to Intensive Pain Rehabilitation Outcomes for Youth With Chronic Pain

OBJECTIVE

An extensive body of research has highlighted the impact that parent/caregiver factors have on functioning and treatment outcomes among youth with chronic pain. However, parent/caregiver expectations in pain treatment have been largely understudied, despite strong evidence that treatment expectations are associated with treatment engagement and overall outcomes in nonpain populations. Accordingly, the primary aim of this investigation was to preliminarily examine the manifestation and measurement of parent/caregiver treatment expectations in an intensive interdisciplinary pediatric pain treatment (IIPT) setting.

METHODS

Participants in this study (N=328) included children and adolescents who attended an IIPT program for chronic pain between August 2013 and March 2020 and their parent/caregiver(s). Outcomes examined include parent/caregiver self-report of treatment expectations for their child upon admission to the IIPT in addition to pain-related and psychosocial factors at admission and discharge.

RESULTS

Findings revealed a high level of expectations (ie, belief that the treatment will be helpful) on average, with higher parent/caregiver expectations associated with poorer functioning at admission to and discharge from the IIPT program.

CONCLUSION

Extremely high treatment expectations among parents of more disabled youth may be indicative of unrealistic hopes or the "need" for IIPT to help their child; tempering parental expectations with psychoeducation about IIPT goals and realistic outcomes may indirectly improve treatment outcomes for their children. Future research should examine the potentially unique and important role that treatment expectations, of both parent/caregivers and their children, may have in overall IIPT outcomes.

Childhood Adversity among Adults with Chronic Pain: Prevalence and Association with Pain-Related Outcomes

OBJECTIVES

Adverse childhood experiences (ACEs) have been linked to the development and impact of chronic pain in adulthood. The goal of this study was to investigate the prevalence of ACEs in a treatment-seeking sample of adults with chronic pain and the relationship between number and type(s) of ACEs and pain-related outcomes.

METHODS

Adults (N=1794) presenting for treatment at a multidisciplinary pain management center completed self-report measures of childhood adversity, pain, functioning, emotional distress, and adjustment to pain.

RESULTS

Participants endorsing ≥4 ACEs had significantly worse pain-related outcomes and lower quality of life compared to individuals reporting fewer ACEs. Having ≥3 ACEs was associated with higher anxiety and depression levels. Experiences of childhood neglect negatively affected mental health-related outcomes independent of number of ACEs. Significant sex differences were found in the number and type of ACEs reported, but not in the relationship between ACEs and outcome variables.

CONCLUSION

Findings suggest that the number and type of self-reported ACE(s) are associated with pain-related variables and psychosocial functioning in adults with chronic pain. Results highlight the importance of assessment of ACEs and trauma-informed care with patients with chronic pain.

A Scoping Review and Proposed Framework for Coping in Youth With a History of Psychological Trauma and Chronic Pain

OBJECTIVE

Psychological trauma (e.g., abuse, neglect) and posttraumatic stress symptoms (PTSS) commonly occur in pediatric pain populations and may be related to various maladaptive coping strategies, which may in turn affect short- and long-term pain-related outcomes in youth. Accordingly, the current scoping review and conceptual framework seeks to identify important gaps in the field's current understanding of how coping impacts outcomes in youth who have experienced trauma/PTSS and pediatric chronic pain and explores avenues for future investigation.

METHODS

A scoping review of the literature was performed in Medline, Embase, Cochrane Library, PsycInfo, and Sociological Abstracts. Eligibility criteria included pediatric populations experiencing chronic pain, trauma, adverse childhood events, and/or PTSS and associated coping mechanisms. Nine research papers were selected and used to support the conceptual framework. The framework builds upon the work of Compas et al.'s' model of control-based coping (Compas et al., 2006; Compas & Harding Thomsen, 1999) and outlines the potential effects of trauma and/or PTSS and pain on coping and pain-related outcomes (e.g., pain chronicity, functional outcomes) in pediatric chronic pain populations.

RESULTS

A history of chronic pain and psychological trauma and/or PTSS in youth may contribute to increased risk for maladaptive coping and in turn, poorer pain-related and psychosocial outcomes long-term.

CONCLUSIONS

Findings from the current scoping review and proposed conceptual framework will guide future research and treatment efforts for youths experiencing pain and trauma and/or PTSS and thereby enhance long-term outcomes.

Adverse Childhood Experiences (ACEs) and Internalizing Mental Health, Pain, and Quality of Life in Youth With Chronic Pain: A Longitudinal Examination

The aims of this longitudinal study were to 1) identify categories of adverse childhood experiences (ACEs) (ie, neglect, abuse, household dysfunction in childhood) that increase risk for internalizing mental health problems, pain-related impairment, and poorer quality of life and 2) examine the moderating role of posttraumatic stress symptoms (PTSS) in these associations, in a clinical sample of youth with chronic pain. At 2 timepoints, youth (N = 155; aged 10-18 years) completed measures of exposure to ACEs, PTSS, depressive and anxiety symptoms, pain intensity, pain interference, and quality of life. Multivariate analyses of variance, linear mixed modeling, and moderation analyses were conducted. Results from cross-sectional and longitudinal analyses were similar; youth with a history of 3+ ACEs reported significantly higher PTSS, depressive and anxiety symptoms, and poorer quality of life than youth with no ACE history. Results also revealed differences in functioning between youth exposed to different types of ACEs (ie, maltreatment only, household dysfunction only, both, none). Finally, PTSS was found to moderate the association between ACEs and anxiety and depressive symptoms. Findings underscore the influence that ACEs can have on the long-term functioning of youth with chronic pain as well as the important role of current PTSS in this association. PERSPECTIVE: This study found that the risk of poorer outcomes imposed by ACEs at baseline remains longitudinally and that posttraumatic stress symptoms (PTSS) moderate the relationship between ACEs and anxiety and depressive symptoms in youth with chronic pain. These results underscore the importance of assessing for ACEs and PTSS alongside chronic pain in youth.

Biomarkers of Allostatic Load as Correlates of Impairment in Youth with Chronic Pain: An Initial Investigation

Pediatric chronic pain is common and responsible for significant healthcare burden. However, the mechanisms underlying the development and/or maintenance of pediatric chronic pain remain poorly understood. Allostatic load (AL), or wear and tear on the nervous system following significant or prolonged stress, has been proposed to play a role in the maintenance of chronic pain, but minimal research has examined this possibility. This gap in research is particularly notable given the high exposure to adverse childhood experiences (ACEs; abuse/neglect, etc.) and psychological stress in this population. Accordingly, the current study aimed to preliminarily examine the measurement of AL in a treatment-seeking pediatric pain population. Biomarkers were collected during an already scheduled new patient pain evaluation and included salivary cortisol, dehydroepiandrosterone (DHEA), and C-reactive protein, in addition to waist-hip ratio, body-mass index, and blood pressure. A total of 61 children and adolescents with chronic pain (Mage = 14.47 years; 88.5% female and white/Caucasian) completed study procedures and were included in analyses. Preliminary results indicated that a multifactorial AL composite is feasible to assess for in a tertiary pain treatment setting and that over 50% of youth with chronic pain were classified as high risk for AL (two or more risk factors). Further, it was found that individual AL risk factors were significantly associated with functional disability and that AL may moderate the association between psychosocial and functional outcomes. Given the pilot nature of this study, results should be used to inform future investigations with larger and more diverse pediatric pain samples.

Adverse Childhood Experiences and Chronic Pain Rehabilitation Treatment Outcomes in Adults

OBJECTIVES

Adverse childhood experiences (ACEs) are commonly reported by individuals with chronic pain. However, little is known about how ACE exposure influences treatment outcomes. The goal of the current study was to evaluate group and treatment-related differences among adults with varying levels of ACE exposure participating in a pain rehabilitation treatment program.

METHODS

Adult participants (N=269) were categorized as 0 ACEs (n=65), 1 to 2 ACEs (n=87), or ≥3 ACEs (n=117). Participants completed self-report measures of pain, physical functioning, and psychosocial functioning at intake and discharge from a 10-week interdisciplinary pain rehabilitation program.

RESULTS

ACE exposure was frequently endorsed in this sample, with the majority of participants (78.5%) reporting at least 1 form of childhood adversity. Adults in the ≥3 ACEs group reported a greater level of impairment in mental health symptoms and adjustment to chronic pain; however, all groups endorsed treatment improvements and there were no differences in response to treatment. There were also no differences between groups on measures of pain or physical functioning at intake or discharge.

DISCUSSION

ACE exposure appears common among treatment-seeking adults with chronic pain and is associated with increased clinical complexity. However, adults with and without exposure to ACEs endorsed significant improvements in pain and functioning following participation in an interdisciplinary pain rehabilitation program. This model of treatment may be especially well situated to address the biopsychosocial contributions to pain among those with a history of adversity.

Social deprivation and paediatric chronic pain referrals in Ireland: a cross-sectional study

OBJECTIVES

Social deprivation is associated with a higher prevalence of chronic pain in children and an under-representation in specialist paediatric chronic pain programs. Our primary objective was to determine if there was a relationship between social deprivation and paediatric chronic pain referrals in Ireland. Secondary objectives included analysing for differences between deprivation groups in pain characteristics and function that are recorded at first clinic visit.

METHODS

Families attending the national paediatric complex pain service in Dublin, Ireland, complete questionnaires on pain characteristics, parental pain catastrophizing, and pain-related disability including sleep quality and school attendance. We retrospectively reviewed records from between February 2016 and November 2019 on 288 patients. Social deprivation was assessed using the Pobal HP Deprivation Index, which is based on data from the Irish national census.

RESULTS

Referrals followed a normal distribution across deprivation grades. Children in the disadvantaged group had a longer duration of pain, greater use of screens at bedtime, and longer sleep onset latency. Parents in the disadvantaged group had significantly higher levels of parental pain catastrophizing.

CONCLUSIONS

In Ireland, while paediatric chronic pain referrals were normally distributed across deprivation group, the disadvantaged group was different in several ways that may be clinically significant. Further work will be needed to determine the longitudinal relationship between these factors before and after the referral and initial review. Screening for, and targeting, potential risk factors for pain chronicity may be needed to harmonize treatment outcomes in children from socially disadvantaged families.

The Relationship between Stressors and Pain-Related Clinical Outcomes in Pediatric Chronic Pain Patients

Youth with chronic pain and youth who have experienced stressors are at risk for poor outcomes; however, little is known about the intersection of pain and stressors. This study aims to understand the prevalence of stressors among youth with chronic pain and the relationship between stressors and pain-related outcomes. Seven hundred and seventy youth with chronic pain aged 8–18 (M_age = 14.15 years, 70% female) reported pain characteristics, stressors, anxiety, disability, and quality of life. Most participants (82%) endorsed at least one stressor. A greater number of stressors was significantly related to greater anxiety and disability, and lower levels of quality of life. School stressors were significantly associated with functional disability; family, school, and peer stressors were significantly associated with anxiety and quality of life. Stressors are common in youth with chronic pain, and the presence of stressors is related to greater functional impairment. The results of this preliminary study using semi-structured clinical interviews suggest the importance of developing a validated measure that encompasses a wide variety of stressors for youth with pain. Future research on patient-reported stressors, relative intensity, and impact are needed.

Adverse childhood experiences and chronic pain among children and adolescents in the United States

Objective

To evaluate the association between adverse childhood experiences (ACEs) and chronic pain during childhood and adolescence.

Methods

Cross-sectional analysis of the 2016-2017 National Survey of Children's Health, including 48,567 child participants of 6 to 17 years of age. Parents of children reported on 9 ACEs. Chronic pain was defined as parents reporting that their children had "frequent or chronic difficulty with repeated or chronic physical pain, including headache or other back or body pain during the past 12 months." Multivariate logistic regression analysis adjusted for sociodemographic and health-related factors.

Results

In this nationally representative sample, 49.8% of children were exposed to one or more ACEs during their lifetime. Children with exposure to 1 or more ACEs had higher rates of chronic pain (8.7%) as compared to those with no reported ACEs (4.8%). In multivariate analysis, children with ACEs had increased odds for chronic pain (adjusted odds ratio [aOR]: 1.6, 95% confidence interval [CI]: 1.3-2.2, for 0 vs 1 ACE and aOR: 2.7, 95% CI: 2.1-3.4 for 0 vs 4+ ACEs). The strongest associations of individually measured ACEs with chronic pain included financial instability (aOR: 1.9, 95% CI: 1.6-2.2), living with a mentally ill adult (aOR: 1.8, 95% CI: 1.5-2.2), and having experienced discrimination based on race (aOR: 1.7, 95% CI: 1.3-2.2).

Conclusions

Children and adolescents with ACEs had increased risk for chronic pain, and this association increased in a dose-dependent fashion.

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

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