The Influence of Children's Pain-Related Attention Shifting Ability and Pain Catastrophizing Upon Negatively Biased Pain Memories in Healthy School Children. THE JOURNAL OF PAIN 2023; 24:2140-2152. [PMID: 37385420 DOI: 10.1016/j.jpain.2023.06.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 05/23/2023] [Accepted: 06/08/2023] [Indexed: 07/01/2023]
Abstract
The current study investigated the influence of children's ability to flexibly shift attention toward and away from pain information on the development of negatively biased pain memories, thereby employing a direct measure of attention control reliant on behavioral responses in the context of pain (ie, an attention switching task). The direct influence of children's attention-shifting ability and pain catastrophizing as well as the moderating role of this shifting ability in the relationship between pain catastrophizing and the development of negatively biased pain memories was examined. Healthy school children (N = 41; 9-15 years old) received painful heat stimuli and completed measures of state and trait pain catastrophizing. They then performed an attention-switching task wherein they had to shift attention between personally relevant pain-related and neutral cues. Two weeks after the painful task, children's pain-related memories were elicited via telephone. Findings indicated that children's reduced ability to disengage attention away from pain information predicted more fear memory bias 2 weeks later. Children's pain-related attention-shifting ability did not moderate the relationship between children's pain catastrophizing and negatively biased pain memories. Findings highlight the contribution of children's attention control skills in the development of negatively biased pain memories. PERSPECTIVE: Results of the current study indicate that children with a reduced ability to shift attention away from pain information are at risk for developing negatively biased pain memories. Findings can inform interventions to minimize the development of these maladaptive negatively biased pain memories by targeting pain-relevant attention control skills in children.

A Brief Mindfulness Intervention for Parents and Children before Pediatric Venipuncture: A Randomized Controlled Trial. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9121869. [PMID: 36553313 PMCID: PMC9776747 DOI: 10.3390/children9121869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 11/14/2022] [Accepted: 11/26/2022] [Indexed: 12/03/2022]
Abstract
BACKGROUND Routine needle procedures can be distressing for parents and children. Mindfulness interventions may be helpful for parents and children but have not been examined for pediatric needle procedures despite showing benefits in the context of pediatric chronic pain and in lab-based pain tasks. METHODS This preregistered (NCT03941717) two-arm, parallel-group randomized controlled trial examined the effects of a 5 min mindfulness intervention before pediatric venipuncture for parents and children (aged 7-12) compared to a control group on primary outcomes of child pain and fear, secondary outcomes of parent distress, and tertiary outcomes of parent ratings of child pain and fear. Moderators of parent and children's responses to the intervention were examined: state catastrophizing, trait mindfulness, and experiential avoidance. RESULTS Sixty-one parent-child dyads were randomized (31 mindfulness; 30 control). Parents and children completed measures, listened to a 5 min audio recording (mindfulness or control), and parents accompanied their child during routine venipuncture. The mindfulness intervention involved breathing and encouraging nonjudgmental attention to one's experiences, while the control condition involved an unfocused attention task. Three between-subject MANCOVAs assessed for group differences. Child pain and fear rated by children and their parents did not differ between groups. Parents in the mindfulness group were less distressed during the venipuncture than the controls. Parent state catastrophizing may have moderated the intervention effects, such that parents with moderate and high catastrophizing levels had lower distress following the mindfulness intervention versus control. CONCLUSIONS The intervention did not reduce child pain or fear but reduced parent distress. It appeared most helpful for parents catastrophizing about their child's pain, which is noteworthy as these children are prone to worse outcomes.

The Effect of Robot-Led Distraction during Needle Procedures on Pain-Related Memory Bias in Children with Chronic Diseases: A Pilot and Feasibility Study. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9111762. [PMID: 36421211 PMCID: PMC9688830 DOI: 10.3390/children9111762] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 11/09/2022] [Accepted: 11/14/2022] [Indexed: 11/19/2022]
Abstract
The current study evaluated the feasibility and preliminary clinical impact of robot-led distraction during needle procedures in children with chronic diseases on pain-related memories. Participants were 22 children (8−12 years old) diagnosed with a chronic disease (e.g., chronic immune deficiency) and undergoing a needle procedure as part of their routine treatment. Children were randomized to the experimental group (i.e., robot-led distraction) or control group (i.e., usual care). For feasibility, we evaluated study- and needle-procedure-related characteristics, intervention fidelity and acceptability, and nurse perceptions of the intervention. Primary clinical outcomes included children’s memory bias for pain intensity and pain-related fear (1 week later). Results indicated that intervention components were >90% successful. Overall, the robot-led distraction intervention was perceived highly acceptable by the children, while nurse perceptions were mixed, indicating several challenges regarding the intervention. Preliminary between-group analyses indicated a medium effect size on memory bias for pain intensity (Hedges’ g = 0.70), but only a very small effect size on memory bias for pain-related fear (Hedges’ g = 0.09), in favor of the robot-led distraction intervention. To summarize, while feasible, certain challenges remain to clinically implement robot-led distraction during needle procedures. Further development of the intervention while accounting for individual child preferences is recommended.

The Moderating Role of Attention Control in the Relationship Between Pain Catastrophizing and Negatively-Biased Pain Memories in Youth With Chronic Pain. THE JOURNAL OF PAIN 2021; 22:1303-1314. [PMID: 33989787 DOI: 10.1016/j.jpain.2021.04.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Revised: 04/07/2021] [Accepted: 04/09/2021] [Indexed: 11/19/2022]
Abstract
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.

Abstract
BACKGROUND Pain neuroscience education (PNE) has received increasing research attention demonstrating beneficial effects on pain-related outcomes in adults. Conversely, studies on the effectiveness of PNE in children are scarce. METHODS This study investigated the effect of a pain educational video intervention on child pain-related outcomes (i.e. experienced pain intensity, pain-related fear and catastrophic worry about pain, pain threshold and pain knowledge) in healthy children undergoing an experimental pain task. Furthermore, the moderating role of children's demographic (i.e. sex and age) and psychological (i.e. baseline pain knowledge and anticipated pain intensity, pain-related fear and catastrophic worry) characteristics was examined. Participants were 89 children (Mage = 11.85, SD = 1.78), randomly assigned to either a condition whereby they were instructed to watch a brief pain educational video (i.e. experimental group) or to a control condition whereby they did not watch any video. RESULTS Study findings revealed that accurate pain knowledge and pain threshold were higher amongst children in the experimental group compared to the control group. In contrast with expectations, no main effects of the video intervention were observed for experienced pain intensity, pain-related fear and catastrophic worry. Moderation analyses indicated that the video intervention contributed, in comparison with the control condition, to higher levels of pain knowledge amongst younger children only and to higher pain thresholds amongst boys only. CONCLUSIONS Further investigation is needed to optimize pain educational video interventions and to determine whether more beneficial outcomes can be found in clinical (i.e. non-experimental) situations and in children with persistent or recurring pain problems. SIGNIFICANCE Examining the impact of pain educational interventions within a non-clinical setting is deemed particularly important given that adaptive pain coping strategies likely play an important role in preventing the development and maintenance of future maladaptive pain-related behaviour. Further, study findings provide preliminary evidence of baseline and demographic (i.e. age and sex) characteristics explaining differences in the effect of a pain educational video intervention in pain knowledge and pain-related experiences during experimental pain.

Abstract
Children of parents with chronic pain have higher rates of pain and internalizing (eg, anxiety and depressive) symptoms than children of parents without chronic pain. Parental modeling of pain behaviour and reinforcement of child pain have been hypothesized to underlie these relationships. These mechanisms were tested in a sample of 72 parents with chronic pain and their children (aged 8-15 years). Standardized measures were completed by parents (pain characteristics, pain interference, and child internalizing) and children (pain catastrophizing, pain over previous 3 months, and internalizing). In a laboratory session, children completed the cold pressor task in the presence of their parent, and parent-child verbalizations were coded. Significant indirect effects of parental pain interference on child self-reported (B = 0.12, 95% confidence interval [CI]: 0.01-0.29) and parent-reported (B = 0.16, 95% CI: 0.03-0.40) internalizing symptoms through child pain catastrophizing were found (parental modeling mechanism), and were not moderated by child chronic pain status. Significant indirect effects were found between parent pain-attending verbalizations and child self-reported (B = 2.58, 95% CI: 1.03-5.31) and parent-reported (B = 2.18, 95% CI: 0.93-4.27) cold pressor task pain intensity and tolerance (B = -1.02, 95% CI: -1.92 to -0.42) through child pain-attending verbalizations (parental reinforcement mechanism). Although further understanding of the temporal relationships between these variables is needed, the current study identifies constructs (eg, parent pain interference, child pain catastrophizing, and parent reinforcement of child pain) that should be further examined as potential targets for prevention and intervention of pain and internalizing symptoms in children of parents with chronic pain.

Abstract
Children commonly undergo painful needle procedures. Unmanaged procedural pain can have short‐ and long‐term consequences, including longer procedure times, greater distress at future procedures, and vaccine hesitancy. While parent behaviors are one of the strongest predictors of children's response to acute pain, pediatric procedural pain management interventions focus almost exclusively on the child. Further, existing parent‐involved pediatric pain management interventions typically fail to improve child self‐reported pain during painful procedures. The current protocol offers the first randomized controlled trial involving a mindfulness intervention for pediatric acute pain that includes children and their parents. This study aims to conduct a single‐site, two‐arm, parallel‐group RCT to examine the effects of a mindfulness intervention for parents and children before child venipuncture compared to a control group on primary (child self‐report of pain and fear), secondary (parent self‐report and child report of parent distress), and tertiary outcomes (parent report of child pain and fear). Parent‐child dyads (n = 150) will be recruited from the McMaster Children's Hospital outpatient blood laboratory. Dyads will be randomly assigned to either a mindfulness group guided through a mindfulness intervention or control group guided through an unfocused attention task. Parents will accompany their child for their venipuncture. Postvenipuncture measures will be collected (eg, child pain‐related outcomes as reported by parents and children). The first enrollment occurred in October 2019. We offer a novel intervention that aims to facilitate both parent and child coping during child venipuncture.

Abstract
BACKGROUND There is no consensus regarding the most effective anaesthetic solution for children; nerve block, especially mandibular, can be difficult for general dentists. Therefore, the study aims to compare the efficacy and the adverse events of articaine 4% with epinephrine 1:100 000 with lidocaine 2% with epinephrine 1:100 000 for primary molar extraction using buccal infiltration. METHODS These are data from a parallel triple-blind randomised controlled trial with a computer-generated allocation treatment. Forty-three children aged 6-10 years with a clinical and radiographic indication of primary molar extraction were enrolled. The intervention was local buccal infiltration with articaine 4% compared with lidocaine 2%. The main outcome was pain during anaesthetic injection and tooth extraction. Adverse events were examined as secondary outcomes. Children were treated in a University setting from April to June 2019. RESULTS Both solutions had similar anaesthetic efficacy in primary molar extraction when applied by the infiltrative technique (β -0.47; 95% CI -3.19 to 2.24; P = .76); however, children reported higher mean pain during articaine deposition (β 2.43; 95% CI 0.28-4.57; P = .02). The measured lidocaine pH was 3.19 (0.15) and articaine was 2.43 (0.00) (P = .04). Post-operative pain, oedema and nausea were observed without differences between the groups. CONCLUSIONS There was no difference in the efficacy of articaine compared to lidocaine for primary molar extraction. Articaine was more painful during the injection. PRACTICAL IMPLICATIONS Primary molar extractions can be performed with both articaine and lidocaine buccal infiltration.

Abstract
Objectives: Pain is reported as one of the most common and difficult symptoms for children and adolescents with cancer to cope with. Pain catastrophizing has been identified as a process clearly related to pain intensity and disability. The Pain Catastrophizing Scale for Children (PCS-C) has been validated in several languages and populations but remains to be validated in pediatric oncology. The aim of the study was to validate a Swedish version of the PCS-C for children and adolescents with cancer. Methods: All children, 7–18 years of age, being treated for cancer in Sweden at the time of the study were invited to participate. Study material was sent out to the registered address. Internal consistency, test–retest reliability and convergent validity were calculated. Factor structure was examined using principal component analysis (PCA). Descriptive statistics were used to investigate background data and norm values. Results: 61 children/adolescents were included in the analyses. The results did not support the original three-factor structure of the PCS-C, but rather suggested that a two-factor structure excluding item 8 best represented the data. The internal consistency of that solution was good (α=0.87), the test–rest reliability was excellent (ICC=0.75) and convergent validity was demonstrated (r=0.46). The mean (SD) for the PCS-C in the sample was 19.1 (9.2), without item 8. A statistically significant difference was shown between genders, where girls reported a higher level of pain catastrophizing than boys. No difference was found with regard to age. Discussion: The Swedish version of the PCS-C is now preliminarily validated for children and adolescents with cancer, for whom gender- and age-specific norm values are now available. Questions remain regarding the optimal factor structure of the PCS-C.

Abstract
Objectives Pain is reported as one of the most common and burdensome symptoms for children with cancer. Pain catastrophizing is clearly related to pain intensity and disability. Catastrophizing in parents is associated with both child functioning and parent distress. The Pain Catastrophizing Scale for Parents (PCS-P) remains to be validated for parents of children with cancer. The aim of the study was to validate the Swedish version of the PCS-P for parents of children with cancer experiencing pain. Methods Parents of all children who were being treated for cancer in Sweden at the time of the study were invited to participate. Study material was sent out to the registered address. Internal consistency, test–retest reliability, and convergent validity were calculated, and factor analysis was conducted. Descriptive statistics was used to investigate the background data and norm values. Results A total of 243 parents participated in the study. The results did not support the original three-factor structure of the PCS-P, but rather suggested that a two-factor structure best represented the data. The results showed excellent internal consistency (a=0.93), excellent temporal stability (intraclass correlation coefficient =0.86) and moderate convergent validity (r=0.57). The mean (SD) for the PCS-P in the sample was 28.3 (10.7). A statistically significant difference was found between mothers and fathers, where mothers reported a higher level of pain catastrophizing than fathers. Conclusion The psychometric properties of the PCS-P has now been supported in a sample of parents of children with cancer, and norm values are now available. The factor structure does, however, deserve more investigation.

Abstract
A burn injury event and subsequent hospitalization are potentially distressing for children. To elucidate the child’s experience of pediatric burn injury, children’s reflections on the burn event and its aftermath were examined. Semi-structured interviews were conducted with eight children (12–17 years old). Using thematic analysis, interview transcripts were coded and codes were combined into overarching categories. Three categories were identified: vivid memories; the importance of parental support; psychosocial impact and coping. Implications for care are discussed in terms of assessing children’s appraisals, paying attention to the parent’s role, and preparing families for potential psychological barriers after discharge.

Abstract
Objective To explore relations between family functioning and child acute pain, including pain ratings, coping, and parent–child behaviors. Methods Community sample of 171 dyads including one child aged 8–12 years (52% girls) and one parent (79% mothers). Family functioning was assessed via child and parent self-report, and observation during a conflict discussion task. Children and parents rated pain catastrophizing at baseline, and child pain and distress following a cold pressor task (CPT). Parent–child interactions during the CPT were coded for observed behaviors during child pain. Results Self-report of poorer family functioning predicted greater child and parent pain catastrophizing, and parent distress. Less observed family negativity/conflict and cohesiveness, and greater family focus of problems and parent emotional support predicted more child symptom complaints. Family functioning was not associated with child pain or distress. Conclusions Family functioning influenced parent and child coping and child behavioral responses, but not the experience, of acute pain.

Abstract
BACKGROUND Although a parent's perception of his or her child's physical and emotional functioning may influence the course of the child's medical care, including access to care and decisions regarding treatment options, no studies have investigated whether the perceptions of a parent are concordant with that of an adolescent diagnosed with a sports-related orthopaedic injury. Identifying and understanding the potential discordance in coping and emotional distress within the athlete adolescent-parent dyads are important, because this discordance may have negative effects on adolescents' well-being. QUESTIONS/PURPOSES The purposes of this study were (1) to compare adolescent and parent proxy ratings of psychologic symptoms (depression and anxiety), coping skills (catastrophic thinking about pain and pain self-efficacy), and upper extremity physical function and mobility in a population of adolescent-parent dyads in which the adolescent had a sport-related injury; and (2) to compare scores of adolescents and parent proxies with normative scores when such are available. METHODS We enrolled 54 dyads (eg, pairs) of adolescent patients (mean age 16 years; SD = 1.6) presenting to a sports medicine practice with sports-related injuries as well as their accompanying parent(s). We used Patient-reported Outcomes Measurement Information System questionnaires to measure adolescents' depression, anxiety, upper extremity physical function, and mobility. We used the Pain Catastrophizing Scale short form to assess adolescents' catastrophic thinking about pain and the Pain Self-efficacy Scale short form to measure adolescents' pain self-efficacy. The accompanying parent, 69% mothers (37 of 54) and 31% fathers (17 of 54), completed parent proxy versions of each questionnaire. RESULTS Parents reported that their children had worse scores (47 ± 9) on depression than what the children themselves reported (43 ± 9; mean difference 4.0; 95% confidence interval [CI], -7.0 to 0.91; p = 0.011; medium effect size -0.47). Also, parents reported that their children engaged in catastrophic thinking about pain to a lesser degree (8 ± 5) than what the children themselves reported (13 ± 4; mean difference 4.5; 95% CI, 2.7-6.4; p < 0.001; large effect size 1.2). Because scores on depression and catastrophic thinking were comparable to the general population, and minimal clinically important difference scores are not available for these measures, it is unclear whether the relatively small observed differences between parents' and adolescents' ratings are clinically meaningful. Parents and children were concordant on their reports of the child's upper extremity physical function (patient perception 47 ± 10, parent proxy 47 ± 8, mean difference -0.43, p = 0.70), mobility (patient perception 43 ± 9, parent proxy 44 ± 9, mean difference -0.59, p = 0.64), anxiety (patient perception 43 ± 10, parent proxy 46 ± 8, mean difference -2.1, p = 0.21), and pain self-efficacy (patient perception 16 ± 5, parent proxy 15 ± 5, mean difference 0.70, p = 0.35). CONCLUSIONS Parents rated their children as more depressed and engaging in less catastrophic thinking about pain than the adolescents rated themselves. Although these differences are statistically significant, they are of a small magnitude making it unclear as to how clinically important they are in practice. We recommend that providers keep in mind that parents may overestimate depressive symptoms and underestimate the catastrophic thinking about pain in their children, probe for these potential differences, and consider how they might impact medical care.

Abstract
Parents of children with Type 1 diabetes (T1D) experience high levels of distress, which may negatively impact child functioning. However, little is known about mechanisms that may buffer the adverse impact of parental distress. The current study explored the possible buffering role of maternal adaptive cognitive emotion regulation (CER) for the relationship between maternal distress and child psychological functioning. Forty-three children with T1D (8-15 years) completed measures assessing trait anxiety and depressive symptoms. Their mothers reported on general distress, illness-related parenting stress, and adaptive CER. Maternal illness-related parenting stress (but not general distress) was significantly associated with child psychological functioning. No buffering role for maternal adaptive CER was observed. As the current study is rather preliminary, future research using other methods to examine maternal adaptive CER, and examining other parental variables that may buffer against the negative impact of parental distress is warranted.

Abstract
Objective To conduct a systematic review of the interrelationships between children's coping responses, children's coping outcomes, and parent variables during needle-related procedures. A systematic literature search was conducted. It was required that the study examined a painful needle-related procedure in children from 3 to 12 years of age, and included a children's coping response, a children's coping outcome, and a parent variable. In all, 6,081 articles were retrieved to review against inclusion criteria. Twenty studies were included. Parent coping-promoting behaviors and distress-promoting behaviors enacted in combination are the most consistent predictors of optimal children's coping responses, and less optimal children's coping outcomes, respectively. Additional key findings are presented. Children's coping with needle-related procedures is a complex process involving a variety of different dimensions that interact in unison. Parents play an important role in this process. Future researchers are encouraged to disentangle coping responses from coping outcomes when exploring this dynamic process.

Abstract
BACKGROUND Supplementary pain-related recommendations for the treatment of chronic pain in children and adolescents are an essential component of multimodal pain treatment. Studies are scarce regarding adherence to these recommendations and their effectiveness. OBJECTIVE The aim of this study was to evaluate patient adherence to pain-related recommendations and their effectiveness 12 months after initial presentation of children and adolescents with chronic pain to a pediatric outpatient pain clinic. MATERIALS AND METHODS A total of 413 patients were assessed using a structured telephone interview. The assessment included pain characteristics during the last 4 weeks as well as information regarding the implementation of the pain-related recommendations and the effectiveness. Due to different recommendations given to migraine patients this subgroup was dealt with separately. RESULTS Patients reported significant improvements 12 months after the initial presentation and 29.5 % of the patients were pain free. Adherence levels and estimated effectiveness regarding recommendations, such as change of lifestyle, multimodal inpatient treatment and use of medication were high. Other recommendations, such as active relaxation and outpatient psychotherapy had low adherence levels and low estimated effectiveness. Migraine patients had a significantly higher adherence rate and estimated effectiveness regarding the recommendation use of medication than non-migraine patients. CONCLUSION The adherence level as well as the estimated effectiveness regarding the majority of pain-related recommendations was high. Some recommendations had low adherence rates and low estimated effectiveness. These results can help to further improve the performance of outpatient clinics for children and adolescents with chronic pain.

Abstract
When explored separately, child and parent catastrophic thoughts about child pain show robust negative relations with child pain. The objective of this study was to conduct a dyadic analysis to elucidate intrapersonal and interpersonal influences of child and parent pain catastrophizing on aspects of pain communication, including observed behaviours and perceptions of child pain. A community sample of 171 dyads including children aged 8 to 12 years (89 girls) and parents (135 mothers) rated pain catastrophizing (trait and state versions) and child pain intensity and unpleasantness following a cold pressor task. Child pain tolerance was also assessed. Parent-child interactions during the cold pressor task were coded for parent attending, nonattending, and other talk, and child symptom complaints and other talk. Data were analyzed using the actor-partner interdependence model and hierarchical multiple regressions. Children reporting higher state pain catastrophizing had greater symptom complaints regardless of level of parent state pain catastrophizing. Children reporting low state pain catastrophizing had similar high levels of symptom complaints, but only when parents reported high state pain catastrophizing. Higher child and parent state and/or trait pain catastrophizing predicted their own ratings of higher child pain intensity and unpleasantness, with child state pain catastrophizing additionally predicting parent ratings. Higher pain tolerance was predicted by older child age and lower child state pain catastrophizing. These newly identified interpersonal effects highlight the relevance of the social context to children's pain expressions and parent perceptions of child pain. Both child and parent pain catastrophizing warrant consideration when managing child pain.

Abstract
Whether a child has to endure a procedure that incurs acute pain or a child has chronic pain, the impact on the family, especially parents, can be profound. Parents need to be active members of their child's health care team; however, they are often ill equipped to cope with either acute pain stressors or longstanding chronic pain in their children. This article provides an overview of acute and chronic pain, the impact of parent factors on pediatric pain, parental assessments of parent functioning, and parent-based interventions for pediatric pain management. Case examples are used to illustrate the treatments presented.

Abstract
BACKGROUND There is evidence for increased risk of affective disorders (AD) in adults with type 1 diabetes however, the prevalence and characteristics of AD in young people with the condition is unclear. Comorbid AD in type 1 diabetes is associated with deleterious self-management, sub-optimal clinical indicators, reduced quality of life, poorer physical health, increased complications, increased high risk behaviours in adolescence and young adulthood, and earlier mortality. The present study investigated the prevalence and character of AD in young people with type 1 diabetes. METHODS The self-report PH-PANAS-C was employed in a cross-sectional, case-control design to identify and differentiate full-syndrome (FS) and subthreshold (St) levels of AD in 53 participants with type 1 diabetes (case) and 54 age-balanced controls (N=107; 7-18 yrs). RESULTS Case participants reported greater AD than controls. When differentiated, only anxiety was significantly more prevalent. Case participants reported less positive affect, and greater negative affect and autonomic arousal. Further, 1:3 case participants presented with St symptoms of AD. LIMITATIONS Self-report measures are known to produce moderated responses therefore symptoms may be more severe than reported. There has been some suggestion that responses to somatic items in the PH-PANAS-C may relate to diabetes-specific states rather than affect-related symptoms however, recent evidence has refuted this argument. CONCLUSIONS AD, particularly anxiety, represents a significant clinical concern in young people with type 1 diabetes both as a disorder in its own right and as a major impediment to primary care and management of the diabetes. The significant dominance of anxiety-related symptoms and prevalence of subthreshold presentation warrant further investigation.

Conditioned pain modulation in children and adolescents: effects of sex and age. THE JOURNAL OF PAIN 2013; 14:558-67.

Abstract
UNLABELLED Conditioned pain modulation (CPM) refers to the diminution of perceived pain intensity for a test stimulus following application of a conditioning stimulus to a remote area of the body, and is thought to reflect the descending inhibition of nociceptive signals. Studying CPM in children may inform interventions to enhance central pain inhibition within a developmental framework. We assessed CPM in 133 healthy children (mean age = 13 years; 52.6% girls) and tested the effects of sex and age. Participants were exposed to 4 trials of a pressure test stimulus before, during, and after the application of a cold water conditioning stimulus. CPM was documented by a reduction in pressure pain ratings during cold water administration. Older children (12-17 years) exhibited greater CPM than younger children (8-11 years). No sex differences in CPM were found. Lower heart rate variability at baseline and after pain induction was associated with less CPM, controlling for child age. The findings of greater CPM in the older age cohort suggest a developmental improvement in central pain inhibitory mechanisms. The results highlight the need to examine developmental and contributory factors in central pain inhibitory mechanisms in children to guide effective, age appropriate pain interventions. PERSPECTIVE In this healthy sample, younger children exhibited less CPM than did older adolescents, suggesting a developmental improvement in CPM. Cardiac vagal tone was associated with CPM across age. The current findings may inform the development of targeted, developmentally appropriate pain interventions for children.

Abstract
BACKGROUND Parental behaviors, emotions, and cognitions are known to influence children's response to pain. However, prior work has not tested the association between maternal psychological factors and children's responses to a conditioned pain modulation (CPM) task. CPM refers to the reduction in perceived pain intensity for a test stimulus following application of a conditioning stimulus to a remote area of the body, and is thought to reflect the descending inhibition of nociceptive signals. METHODS The present study examined sex differences in the association between maternal anxiety about pain and children's CPM responses in 133 healthy children aged 8-17 years. Maternal pain anxiety was assessed using the Pain Anxiety Symptoms Scale-20. In addition to the magnitude of CPM, children's anticipatory anxiety and pain-related fear of the CPM task were measured. RESULTS Sequential multiple linear regression revealed that even after controlling for child age and general maternal psychological distress, greater maternal pain anxiety was significantly related to greater CPM anticipatory anxiety and pain-related fear in girls, and to less CPM (ie, less pain inhibition) in boys. CONCLUSION The findings indicate sex-specific relationships between maternal pain anxiety and children's responses to a CPM task over and above that accounted for by the age of the child and the mother's general psychological distress.
