Adverse childhood experiences in parents of youth with chronic pain: prevalence and comparison with a community-based sample

Intergenerational associations between childhood maltreatment, post-traumatic stress symptoms, and chronic pain in young adult offspring and their parents

Findings have revealed a strong link between exposure to child maltreatment (CM) and later chronic pain. Concurrently, other findings have been grounded in the understanding that CM consequences may not end with the exposed individual, rather, they extend to their offspring. However, little is known regarding the possible intergenerational transmission of chronic pain following CM. This study examines whether chronic pain among parents and their young adult offspring may be associated with parental exposure to CM. Three hundred ninety-three parent-offspring dyads (parents' mean age = 58, SD = 5.91 years; offspring's mean age = 27, SD = 3.91 years) completed self-report questionnaires, assessing CM (CTQ), posttraumatic stress (PTS) and disturbances in self-organisation (DSO) symptoms (ITQ), and chronic pain. CM was associated with chronic pain mediated by DSO symptoms among parents (indirect effect = 0.77; p = 0.007) and PTS symptoms among offspring (indirect effect = 0.285; p = 0.005). Offspring chronic pain was significantly associated with parental CM through two intergenerational paths: the mediation of parents' DSO symptoms and chronic pain (indirect effect = 0.298; p = 0.011), and through parents' PTS symptoms and offspring's PTS symptoms (indirect effect = 0.077; p = 0.004). This study's findings support the relevance of the intergenerational transmission of chronic pain following parental exposure to CM. Furthermore, the findings reveal complex PTS symptoms as a possible underlying mechanism for the intergenerational associations of chronic pain following CM.

The relationship between traumatic exposure and pain perception in children: the moderating role of posttraumatic symptoms

ABSTRACT

Adverse childhood experiences (ACEs) affect approximately half of all children worldwide. These experiences have been linked to increased pain sensitivity in adulthood and a higher likelihood of developing severe chronic pain. However, most studies have assessed the effects of ACEs retrospectively, long after they occurred, leaving room for other factors to influence the observed outcomes. We investigated, for the first time, the association between ACEs and concurrent pain perception among young children who live in a conflict zone and are consistently exposed to potentially traumatic experiences. Participants were 60 elementary school children (ages 8-11 years) living in conflict regions (n = 39) or nonconflict regions (n = 21). Posttraumatic stress symptom (PTSS) severity, traumatic exposure, pressure pain threshold (PPT), and mechanical detection threshold (MDT) were measured. Trauma-exposed children had significantly lower PPT than did controls, but MDT was similar across groups. Pressure pain threshold correlated positively with proximity to the conflict zone and inversely with traumatic exposure magnitude and PTSS severity. In addition, PTSSs moderated the relationship between repeated traumatic exposure and PPT. Children with higher PTSS severity displayed pain hypersensitivity regardless of their traumatic exposure level, whereas in children with lower PTSS severity, greater traumatic exposure correlated with pain hypersensitivity. The results suggest that ACEs among children lead to concurrent pain hypersensitivity and distress and may put them at elevated risk of chronic pain early in life. In addition, our findings emphasize the need for identifying children with various PTSS levels to provide tailored interventions and mitigate the long-term negative effects of ACEs.

Peer Victimization, Posttraumatic Stress Symptoms, and Chronic Pain: A Longitudinal Examination

Chronic pain and posttraumatic stress disorder symptoms (PTSS) co-occur at high rates in youth and are linked to worse pain outcomes and quality of life. While peer victimization has been posited as a mechanism underlying the PTSS-pain relationship in youth, empirical evidence suggests that it may exacerbate both PTSS and pain. The present study aimed to longitudinally examine PTSS as a mediator in the relationship between peer victimization at baseline and pain-related outcomes at 3 months in youth with chronic pain. Participants included 182 youth aged 10 to 18 years recruited from a tertiary-level children's hospital in Western Canada. At baseline, participants completed measures to assess pain (intensity and interference), peer victimization (relational and overt), and PTSS. The pain was reassessed at a 3-month follow-up. Primary hypotheses were tested utilizing a series of mediation analyses with PTSS as a proposed mediator in the associations between peer victimization and pain outcomes. Youth PTSS mediated the relationship between higher baseline relational victimization and higher 3-month pain interference while controlling for baseline pain interference. Three-month pain intensity was not correlated with peer victimization; thus, pain intensity was not included in the analyses. These findings reveal that PTSS may be an underlying factor in the co-occurrence of peer victimization and chronic pain in youth. Further research is needed to better understand the role of peer victimization in the maintenance of chronic pain to ensure appropriate, effective, and timely interventions that address the social and mental health issues impacting the lives of these youth as well as their pain. PERSPECTIVE: PTSS may be an underlying factor in the co-occurrence between peer victimization and chronic pain in youth, highlighting the need to assess for both peer relationship problems and PTSS in youth with chronic pain.

Parent-perceived recurrent pain in children: associations with maternal pain, depressiveness, socioeconomic status, and children's behavioural difficulties

Objectives

The current study aimed to examine the potential transgenerational associations between maternal pain and depressiveness and childhood pain, and to explore the associations between the children's difficulties and recurrent pain (defined as pain occurring at least once a month in the previous 6 month) in healthy children aged 3-13 years.

Methods

We collected Data between 2015 and 2019 as part of the LIFE Child study in Germany and investigated associations of maternal pain and depressiveness, child age, sex, pubertal stage, emotional difficulties, conduct difficulties, hyperactivity/inattention, peer group difficulties, and prosocial skills, and family socioeconomic status with the frequency of parent-perceived headache, backache, and stomachache in a sample of 1,850 children (4,819 documented visits) using logistic and ordinal regression analyses.

Results

Overall, 10.4%, 24.4%, and 45.2% of parents reported their children had recurrent backache, headache, and stomachache, respectively, with 5.5% of children were reported to experience all three types of pain simultaneously. Higher age, female sex, puberty, emotional difficulties, low family socioeconomic status, as well as higher maternal impairment due to pain and maternal depressiveness were significantly associated with more frequent pain.

Conclusions

Our study suggests that maternal pain, maternal depressiveness, and lower family socioeconomic status as well as child's emotional difficulties are significantly associated with a higher frequency of recurrent pain in children perceived by their parents.

The Sensitivity to Pain Traumatization Scale-Child Version (SPTS-C): Development and preliminary validation

Background

Sensitivity to pain traumatization is defined as the propensity to develop cognitive, affective, and behavioral responses to pain that resemble a traumatic stress reaction. To date, sensitivity to pain traumatization has been assessed in adults (Sensitivity to Pain Traumatization Scale [SPTS-12]) and parents of youth with chronic pain (Sensitivity to Pain Traumatization Scale-Parent version [SPTS-P]). SPT may be relevant in the context of pediatric chronic pain given the substantial comorbidity between posttraumatic stress symptoms and pain.

Aims

This prospective study aimed to adapt the SPTS-12 for use in youth and to evaluate the psychometric properties of the new scale.

Methods

Participants included 175 youth with chronic pain (Mage = 14.31 years, 73% girls) referred to outpatient chronic pain programs. At baseline, youth self-reported the levels of their sensitivity to pain traumatization (Sensitivity to Pain Traumatization Scale-Child version [SPTS-C]), as well as their pain symptoms, pain-related anxiety, posttraumatic stress symptoms, and attentional control. Three months later, youth self-reported their pain symptoms and completed the SPTS-C.

Results

The SPTS-C had a one-factor structure that explained 48% of variance and demonstrated good reliability and construct validity. SPTS-C baseline scores predicted follow-up levels of pain interference but not pain intensity or pain unpleasantness.

Conclusions

The results provide preliminary evidence for the psychometric properties of the SPTS-C and the potential role of SPT in pediatric chronic pain outcomes.

Family Caregiver Acceptability of Assessing Caregiver Adverse Childhood Experiences (ACEs) and Distress in Pediatric Specialty Care

INTRODUCTION

Providing quality healthcare for children includes assessing and responding to needs of their family caregivers. Three salient domains to consider are caregivers' early adverse childhood experiences (ACEs), their current levels of distress, and their resilience in coping with both prior and current stressors.

OBJECTIVE

Determine acceptability of assessing caregiver ACEs, current distress, and resilience in pediatric subspecialty care settings.

METHODS

Caregivers of patients in two pediatric specialty care clinics completed questionnaires about their ACEs, recent emotional distress, and resilience. Importantly, caregivers also rated the acceptability of being asked these questions. Participants included 100 caregivers of youth ages 3-17 across Sickle Cell Disease and Pain clinic settings. The majority of participants were mothers (91.0%) who identified as non-Hispanic (86.0%). Caregiver race was primarily African American/Black (53.0%) and White (41.0%). The Area Deprivation Index (ADI) was used to assess socioeconomic disadvantage.

RESULTS

High levels of caregiver acceptability or neutrality with assessing ACEs and distress, as well as high ACEs, distress, and resilience. Associations were found between caregiver ratings of acceptability with caregiver resilience and socioeconomic disadvantage. Caregivers reported openness to being asked about their experiences during childhood and recent emotional distress, although ratings of acceptability varied according to other contextual variables, such as level of socioeconomic disadvantage and caregiver resilience. In general, caregivers perceived themselves to be resilient in the face of adversity.

CONCLUSIONS

Assessing caregiver ACEs and distress in a trauma-informed way may provide opportunities for better understanding the needs of caregivers and families in order to support them more effectively in the pediatric setting.

A high-fat high-sugar diet and adversity early in life modulate pain outcomes at the behavioural and molecular level in adolescent rats: The role of sex

Given that adolescence is a significant period of brain plasticity and development, early life factors have the potential to alter long term outcomes. For instance, adversities such as consumption of a high-fat high-sugar (HFHS) diet and adverse childhood experiences (ACEs; e.g., neglect), and their resulting inflammation and microglial activation can influence pain outcomes by priming the neuroimmune system to overrespond to stressors. Chronic pain is highly prevalent amongst the adolescent population, with the prevalence and manifestation being sexually dimorphic. Although clinical studies show that females are twice as likely to report pain problems compared to males, the majority of pre-clinical work uses male rodents. Therefore, our aim was to examine the effects of sex, a HFHS diet, and an ACE on chronic pain outcomes following a stressor in adolescence. Rat dams were randomly assigned to a Standard or HFHS diet, with pups maintained on their respective diets then randomly allocated to a No Stress or ACE paradigm, and a Sham or Injury condition as a stressor. Results showed that early life adversities increased nociceptive sensitivity, inflammation, and microglial activation systemically and within the brain. Behaviourally, pain outcomes were more prominent in females, however the neuroimmune response was exacerbated in males. These results demonstrate the sexual dimorphism of chronic pain outcomes following early life adversities and provide insight into the mechanisms driving these changes, which will inform more targeted and effective treatment strategies for youth living with chronic pain.

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.

The Impact of the COVID-19 Pandemic on Youth with Chronic Pain and Their Parents: A Longitudinal Examination of Who Are Most at Risk

Objectives: Chronic pain and mental illness in youth and parents are poised to reach new heights amidst the societal and healthcare impacts of the COVID-19 pandemic. Evidence from natural disasters (i.e., hurricanes) suggests that a degree of personal impact and individual personality may moderate the effects of high stress events, such as the COVID-19 pandemic, on mental health. Methods: In a pre-existing cohort of 84 youth with chronic pain (M_age = 14.39; 12–18 years; 67.8% female) and 90 parents (86.7% female), we examined changes in youth pain interference and youth and parent mental health (depression, anxiety) from before to during the first wave of the COVID-19 pandemic, and the influence of personal impact of the pandemic (i.e., financial, familial, health, social, occupational, and educational domains) and individual personality (neuroticism, conscientiousness, extroversion). Results: Overall, youth reported significantly lower pain interference and anxiety as compared to pre-pandemic; however, those more personally impacted by the pandemic reported worsening pain interference and anxiety symptoms. Overall, parents reported greater depressive symptoms as compared to pre-pandemic; however, those more personally impacted by the pandemic reported increased anxiety symptoms. Personality traits (high neuroticism, and low conscientiousness and extroversion) predicted worsened pain and mental health, and exacerbated effects of COVID-19-related personal impact on youth and parent anxiety symptoms. Discussion: Identifying risk and resilience profiles in youth and parents at high risk for worsening pain and mental health may better inform matching interventions to individual need.

Pediatric Chronic Pain in the Midst of the COVID-19 Pandemic: Lived Experiences of Youth and Parents

During the coronavirus 2019 (COVID-19) pandemic youth with chronic pain have experienced additional barriers to accessing treatment and managing their pain. This study explored the experiences of youth with chronic pain and their parents during the COVID-19 pandemic. Individual semi-structured interviews were conducted with 20 youth with chronic pain (aged 13-20 years) and one of their parents, recruited from a tertiary level pediatric chronic pain program. Interviews occurred between the months of June to August 2020 and enabled participants to describe their experiences of the COVID-19 pandemic according to their own unique perspectives. Transcripts were analyzed using inductive reflexive thematic analysis. Four themes were generated and labelled: "temporality, mental health, and pain," "coping with pain during a global pandemic," "impact on care," and "re-appraisal in the context of development and pandemic life." Across these themes, youth and parents described their unique challenges of living with pain as they adapted to changing circumstances of the COVID-19 pandemic. Notably, youth experienced increased difficulties managing their mental health and pain, which were intricately connected and related to social isolation, temporality, and uncertainty exacerbated by the COVID-19 pandemic. Restrictions due to the COVID-19 pandemic impacted youth's access to care and their abilities to engage in coping strategies to manage their pain. The COVID-19 pandemic was also perceived to have interrupted youth's development and growing autonomy, prompting youth to re-appraise their current circumstances and imagined futures. PERSPECTIVE: This manuscript provides an in-depth understanding of the impact of the COVID-19 pandemic on youth with chronic pain and their parents. Youth and their parents perceived the COVID-19 pandemic to have impacted youth's mental health, pain, socio-emotional development, and access to care.

Adverse childhood events and substance use history or recent opioid use among women with chronic pelvic pain

Introduction:

We aimed describe the association of adverse childhood events (ACEs) with a history of substance use disorder and recent opioid use among women with chronic pelvic pain (CPP).

Methods:

This cohort study investigated two data sets of women presenting to subspecialty gynecologic and pelvic floor disorder clinics where questionnaires querying substance use disorder, opioid use in the last 3 months, and ACEs (BRFSS-ACE questionnaire) were obtained. We compared the recent opioid use, morphine milligram equivalents (MMEs) per dose, pills used per month, and minimum MMEs reported per month between women with high (⩾4) or low (<4) reported ACEs.

Results:

Patients completing the BRFSS-ACE ( n = 113) were older, more likely to be Hispanic/Latina, had higher levels of education, a higher prevalence of pain syndromes, and a greater degree of bother from pelvic floor disorders than those not completing the BRFSS-ACE. Women reporting a high number of (⩾4) ACEs ( n = 56) were younger, less likely to identify as Hispanic, had higher co-occurrence of fibromyalgia and IBS, and a higher prevalence of a history of substance use disorder (18% vs 2%, p < 0.01) than women with low (<4) ACEs ( n = 57). High ACEs were not significantly associated with recent opioid use (43% vs 39%, p = 0.83), opioid pills used per month, MMEs per dose, or the minimum MMEs used per month.

Conclusion:

Women with CPP reporting higher numbers of ACEs are more likely to report a history of substance use disorder but were not more likely to have used opioids in the last 3 months.

Examining Parent Adverse Childhood Experiences as a Distal Risk Factor in Pediatric Chronic Pain

OBJECTIVES

Adverse childhood experiences (ACEs; ie, exposure to abuse, neglect, household dysfunction in childhood) are associated with poor mental and physical health outcomes across the lifespan. Emerging research suggests parent ACEs also confer risk for poor child outcomes. The relation between parent ACEs and child pain in youth with chronic pain has not yet been examined. The aim of the current longitudinal study was to examine the associations among parent ACEs, parent health, and child pain, in a clinical sample of youth with chronic pain.

METHODS

In total, 192 youth (75.5% female, 10 to 18 y old) and one of their parents (92.2% female) were recruited from tertiary pediatric chronic pain clinics in Canada. At baseline, parents completed self-report measures of ACEs, chronic pain status, anxiety and depressive symptoms, and posttraumatic stress disorder symptoms. At a 3-month follow-up, youth completed self-report measures of pain intensity and pain interference.

RESULTS

Regression and mediation analyses revealed that parent ACEs significantly predicted parent chronic pain status and depressive symptoms, but not parent anxiety or posttraumatic stress disorder symptoms. Moreover, parent ACEs were not significantly related to youth pain, either directly or indirectly through parent health variables.

DISCUSSION

Findings suggest that an intergenerational cascade from parent ACEs to parent health to child pain was not present in the current sample. Further research that examines the role of parent ACEs in the development of child chronic pain, as well as other risk and resiliency factors that may mediate or moderate the association between parent ACEs and child chronic pain, is needed.

Does screening for maternal ACEs in prenatal care predict pregnancy health risk above and beyond demographic and routine mental health screening?

BACKGROUND

Adverse childhood experiences (ACEs), including abuse, neglect, and/or household dysfunction, are associated with physical and mental health difficulties in pregnancy and the postpartum period. These associations have prompted the adoption of screening for ACEs in prenatal care settings; however, little is known about whether asking about ACEs in the prenatal care context is additive to other forms of routine prenatal demographic and mental health screening.

OBJECTIVE

To identify whether ACEs are predictive of cumulative pregnancy health risk and identify whether ACEs predict maternal health risks in pregnancy above and beyond screening for financial stress, depression, and anxiety.

PARTICIPANTS AND SETTING

The electronic medical records of three hundred and thirty-eight patients who accessed prenatal care at a low-risk primary care maternity clinic were included.

METHODS

Women retrospectively self-reported their ACEs during their second prenatal primary care visit (~20 weeks' gestation) and reported financial stress as well as their depressive and anxious symptoms using the PHQ-2 and GAD-2. Health risk factors and complications were documented by healthcare providers in the files at birth. Approximately 32% of patients reported at least one ACE.

RESULTS

Regression analyses revealed that after accounting for financial stress, neither depression nor anxiety predicted cumulative health risk in the antenatal period. ACEs significantly predicted cumulative health risk (B = 0.14, p = .02) and an additional 1.7% of variance in the outcome. However, the model only accounted for 5.0% of the variance in cumulative health risk.

CONCLUSIONS

The total health risk predicted by demographic and ACEs screening is modest in this low-risk sample. Additional research on the implications of broader trauma-informed approaches is needed to evaluate their impact.

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.

The Moderating Role of Attention Control in the Relationship Between Pain Catastrophizing and Negatively-Biased Pain Memories in Youth With Chronic Pain

The present study examined the role of attention control in understanding the development of negatively-biased pain memories as well as its moderating role in the relationship between pain catastrophizing and negatively-biased pain memories. Youth with chronic pain (N = 105) performed a cold pressor task (CPT) and completed self-report measures of state/trait pain catastrophizing and attention control, with the latter comprising both attention focusing and attention shifting. Two weeks after the CPT, youth's pain-related memories were elicited via telephone allowing to compute pain and anxiety memory bias indices (ie, recalling pain intensity or pain-related anxiety, respectively, as higher than initially reported). Results indicated no main effects of attention control and pain catastrophizing on pain memories. However, both components of attention control (ie, attention focusing and attention shifting) moderated the impact of pain catastrophizing on youth's memory bias, with opposite interaction effects. Specifically, whereas high levels of attention shifting buffered the influence of high pain catastrophizing on the development of pain memory bias, high levels of attention focusing strengthened the influence of high pain catastrophizing on the development of anxiety memory bias. Interaction effects were confined to trait catastrophizing (ie, not state catastrophizing). Theoretical and clinical implications are discussed. PERSPECTIVE: This article investigates the role of attention control in the development of negatively-biased pain memories in children with chronic pain. Findings underscore the importance of targeting differential components of attention control and can inform intervention efforts to minimize the development of negatively biased pain memories in youth with chronic pain.

The anatomy of pain and suffering in the brain and its clinical implications

Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Chronic pain, with a prevalence of 20-30 % is the major cause of human suffering worldwide, because effective, specific and safe therapies have yet to be developed. It is unevenly distributed among sexes, with women experiencing more pain and suffering. Chronic pain can be anatomically and phenomenologically dissected into three separable but interacting pathways, a lateral 'painfulness' pathway, a medial 'suffering' pathway and a descending pain inhibitory pathway. One may have pain(fullness) without suffering and suffering without pain(fullness). Pain sensation leads to suffering via a cognitive, emotional and autonomic processing, and is expressed as anger, fear, frustration, anxiety and depression. The medial pathway overlaps with the salience and stress networks, explaining that behavioural relevance or meaning determines the suffering associated with painfulness. Genetic and epigenetic influences trigger chronic neuroinflammatory changes which are involved in transitioning from acute to chronic pain. Based on the concept of the Bayesian brain, pain (and suffering) can be regarded as the consequence of an imbalance between the two ascending and the descending pain inhibitory pathways under control of the reward system. The therapeutic clinical implications of this simple pain model are obvious. After categorizing the working mechanisms of each of the available treatments (pain killers, psychopharmacology, psychotherapy, neuromodulation, psychosurgery, spinal cord stimulation) to 1 or more of the 3 pathways, a rational combination can be proposed of activating the descending pain inhibitory pathway in combination with inhibition of the medial and lateral pathway, so as to rebalance the pain (and suffering) pathways.

The Parent Version of the Sensitivity to Pain Traumatization Scale (SPTS-P): A Preliminary Validation

Sensitivity to pain traumatization (SPT) is defined as the propensity to develop responses to pain that resemble a traumatic stress reaction. To date, SPT has been assessed in adults with a self-report measure (Sensitivity to Pain Traumatization Scale (SPTS-12)). SPT may also be relevant in the context of parenting a child with chronic pain, as many of these parents report clinically elevated posttraumatic stress symptoms (PTSS). This study aimed to develop and validate a measure of parent SPT by adapting the SPTS-12 and evaluating its psychometric properties in a sample of parents whose children have chronic pain. In total, 170 parents (90.6% female) and children (aged 10–18 years, 71.2% female) were recruited from a tertiary chronic pain program. Parents completed the parent version of the SPTS-12 (SPTS-P) and measures of PTSS, depression, anxiety and anxiety-related constructs, and parenting behaviors. Youth completed measures of pain. Consistent with the SPTS-12, the SPTS-P demonstrated a one-factor structure that accounted for 45% of the variance, adequate to good reliability and moderate construct validity. Parent SPT was positively related to their protective and monitoring behaviors but was unrelated to youth pain intensity, unpleasantness, and interference. These results provide preliminary evidence for the psychometric properties of the SPTS-P and highlight the interaction between parent distress about child pain and parent responses to child pain.

A Pilot Study Investigating the Role of Gender in the Intergenerational Relationships between Gene Expression, Chronic Pain, and Adverse Childhood Experiences in a Clinical Sample of Youth with Chronic Pain

Chronic pain is a highly prevalent and costly issue that often emerges during childhood or adolescence and persists into adulthood. Adverse childhood experiences (ACEs) increase risk for several adverse health conditions, including chronic pain. Recent evidence suggests that parental trauma (ACEs, post-traumatic stress disorder (PTSD) symptoms) confers risk of poor health outcomes in their children. Intergenerational relationships between parental trauma and child chronic pain may be mediated by epigenetic mechanisms. A clinical sample of youth with chronic pain and their parents completed psychometrically sound questionnaires assessing ACEs, PTSD symptoms, and chronic pain, and provided a saliva sample. These were used to investigate the intergenerational relationships between four epigenetic biomarkers (COMT, DRD2, GR, and SERT), trauma, and chronic pain. The results indicated that the significant biomarkers were dependent upon the gender of the child, wherein parental ACEs significantly correlated with changes in DRD2 expression in female children and altered COMT expression in the parents of male children. Additionally, the nature of the ACE (maltreatment vs. household dysfunction) was associated with the specific epigenetic changes. There may be different pathways through which parental ACEs confer risk for poor outcomes for males and females, highlighting the importance of child gender in future investigations.

Pain in the Developing Brain: Early Life Factors Alter Nociception and Neurobiological Function in Adolescent Rats

Although adverse early experiences prime individuals to be at increased risk for chronic pain, little research has examined the trauma–pain relationship in early life or the underlying mechanisms that drive pathology over time. Given that early experiences can potentiate the nociceptive response, this study aimed to examine the effects of a high-fat, high-sugar (HFHS) diet and early life stress (maternal separation [MS]) on pain outcomes in male and female adolescent rats. Half of the rats also underwent a plantar-incision surgery to investigate how the pain system responded to a mildly painful stimuli in adolescence. Compared with controls, animals that were on the HFHS diet, experienced MS, or had exposure to both, exhibited increased anxiety-like behavior and altered thermal and mechanical nociception at baseline and following the surgery. Advanced magnetic resonance imaging demonstrated that the HFHS diet and MS altered the maturation of the brain, leading to changes in brain volume and diffusivity within the anterior cingulate, amygdala, corpus callosum, nucleus accumbens, and thalamus, while also modifying the integrity of the corticospinal tracts. The effects of MS and HFHS diet were often cumulative, producing exacerbated pain sensitivity and increased neurobiological change. As early experiences are modifiable, understanding their role in pain may provide targets for early intervention/prevention.

Clinical relevance of attentional biases in pediatric chronic pain: an eye-tracking study

ABSTRACT

Attentional biases have been posited as one of the key mechanisms underlying the development and maintenance of chronic pain and co-occurring internalizing mental health symptoms. Despite this theoretical prominence, a comprehensive understanding of the nature of biased attentional processing in chronic pain and its relationship to theorized antecedents and clinical outcomes is lacking, particularly in youth. This study used eye-tracking to assess attentional bias for painful facial expressions and its relationship to theorized antecedents of chronic pain and clinical outcomes. Youth with chronic pain (n = 125) and without chronic pain (n = 52) viewed face images of varying levels of pain expressiveness while their eye gaze was tracked and recorded. At baseline, youth completed questionnaires to assess pain characteristics, theorized antecedents (pain catastrophizing, fear of pain, and anxiety sensitivity), and clinical outcomes (pain intensity, interference, anxiety, depression, and posttraumatic stress). For youth with chronic pain, clinical outcomes were reassessed at 3 months to assess for relationships with attentional bias while controlling for baseline symptoms. In both groups, youth exhibited an attentional bias for painful facial expressions. For youth with chronic pain, attentional bias was not significantly associated with theorized antecedents or clinical outcomes at baseline or 3-month follow-up. These findings call into question the posited relationships between attentional bias and clinical outcomes. Additional studies using more comprehensive and contextual paradigms for the assessment of attentional bias are required to clarify the ways in which such biases may manifest and relate to clinical outcomes.
