Parental narrative style moderates the relation between pain-related attention and memory biases in youth with chronic pain.

ABSTRACT: Negatively biased pain memories robustly predict maladaptive pain outcomes in children. Both attention bias to pain and parental narrative style have been linked with the development of these negative biases, with previous studies indicating that how parents talk to their child about the pain might buffer the influence of children's attention bias to pain on the development of such negatively biased pain memories. This study investigated the moderating role of parental narrative style in the relation between pain-related attention and memory biases in a pediatric chronic pain sample who underwent a cold pressor task. Participants were 85 youth-parent dyads who reminisced about youth's painful event. Eye-tracking technology was used to assess youth's attention bias to pain information, whereas youth's pain-related memories were elicited 1 month later through telephone interview. Results indicated that a parental narrative style using less repetitive yes-no questions, more emotion words, and less fear words buffered the influence of high levels of youth's attention bias to pain in the development of negatively biased pain memories. Opposite effects were observed for youth with low levels of attention bias to pain. Current findings corroborate earlier results on parental reminiscing in the context of pain (memories) but stress the importance of matching narrative style with child characteristics, such as child attention bias to pain, in the development of negatively biased pain memories. Future avenues for parent-child reminiscing and clinical implications for pediatric chronic pain are discussed.

Racial Differences in Movement-Related Appraisals and Pain Behaviors Among Adults With Chronic Low Back Pain.

Research documents racial disparities in chronic low back pain (CLBP). Few studies have examined racial disparities in movement-related appraisals and no studies have examined anticipatory appraisals prior to or pain behaviors during functional activities among individuals with CLBP. This cross-sectional study examined racial differences in anticipatory appraisals of pain, concerns about harm, and anxiety, appraisals of pain and anxiety during movement, and observed pain behaviors during 3 activities of daily living (supine-to-standing bed task, sitting-to-standing chair task, floor-to-waist lifting task) in a sample (N = 126) of non-Hispanic Black (31.0%), Hispanic (30.2%), and non-Hispanic White (38.9%) individuals with CLBP. Hispanic participants reported more expected pain, concerns about harm, and pre-movement anxiety prior to the bed and chair tasks compared to non-Hispanic White participants. Hispanic participants reported more pain during the bed task and more anxiety during the bed and chair tasks compared to non-Hispanic White participants. Non-Hispanic Black participants reported more expected pain, concerns about harm, and pre-movement anxiety prior to the bed task and more pre-movement anxiety prior to the chair task compared to non-Hispanic White participants. Non-Hispanic Black participants reported more anxiety during the bed and chair tasks compared to non-Hispanic White participants. Non-Hispanic Black participants were observed to have significantly more verbalizations of pain during the bed task compared to non-Hispanic White participants. Current findings identify racial disparities in important cognitive-behavioral and fear-avoidance mechanisms of pain. Results indicate a need to revisit traditional theoretical and treatment models in CLBP, ensuring racial disparities in pain cognitions are considered. PERSPECTIVE: This study examined racial disparities in anticipatory and movement-related appraisals, and pain behaviors during activities of daily living among Non-Hispanic Black, Non-Hispanic White, and Hispanic individuals with CLBP. Racial disparities identified in the current study have potentially important theoretical implications surrounding cognitive-behavioral and fear-avoidance mechanisms of pain.

The Influence of Children's Pain-Related Attention Shifting Ability and Pain Catastrophizing Upon Negatively Biased Pain Memories in Healthy School Children.

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.

Youth baseline and state pain-related injustice appraisals are associated with emotional responses of anger and sadness: An experimental study.

Background: Youth pain-related injustice appraisals are associated with adverse functioning; however, mechanisms by which injustice appraisals exert their impact have yet to be elucidated. Adult injustice literature suggests anger, sadness, and attention bias to anger (AB) as potential mechanisms. This study examined the effects of injustice appraisals in a healthy youth sample by applying a justice violation manipulation. We hypothesized the justice violation condition to lead to worse pain outcomes with effects mediated by anger, sadness, and AB as compared to the control condition. We further explored associations between both baseline and state injustice appraisals and anger, sadness, and AB across conditions. Methods: A 2 × 2 time by condition design was used to test hypotheses. 133 healthy youth aged 9-16 years old completed two cold pressor tasks (CPTs). In the experimental (i.e., justice violation) group, participants were initially told to complete one CPT, but were told afterwards to perform it again due to experimenter negligence. In the control group, no justice violation occurred. Baseline injustice appraisals and pain catastrophizing were assessed with the Injustice Experience Questionnaire and Pain Catastrophizing Scale for Children; state outcomes (i.e., injustice, catastrophizing, anger, sadness) were assessed after CPTs. AB was indexed using a dot-probe task. Results: Findings indicated no effects of the justice violation on pain outcomes or associated mechanisms, nor on injustice appraisals, suggesting manipulation failure. However, across conditions, baseline and state injustice appraisals were positively associated with anger and sadness, but not with AB. Conclusions: Despite the experimental justice violation failing to elicit differential injustice appraisals across conditions, the current study supports both anger and sadness as key emotional responses associated with pain-related injustice appraisals in a healthy youth sample.

The Effect of Robot-Led Distraction during Needle Procedures on Pain-Related Memory Bias in Children with Chronic Diseases: A Pilot and Feasibility Study.

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 relation between children's attention bias to pain and children's pain-related memory biases is moderated by parental narrative style.

Children's heightened attention to pain and parental narrative style have been linked to the development of negatively-biased pain memories in children (i.e., recalling higher levels of pain and fear than initially reported, which robustly predicts maladaptive pain outcomes). However, the interplay between child attention bias and parental narrative style remains to be assessed. This study aims to fill this gap using enhanced paradigms assessing children's cognitive biases for cues signaling actual pain. Healthy school children (N = 63; 9-15 years old) received painful heat stimuli while performing a spatial cueing task measuring attention bias to cues signaling actual pain. Parent-child interaction upon completion of the painful task, was coded for parental narrative style (i.e., elaboration, repetition and evaluation). Children's pain-related memories were elicited two weeks later. Findings indicated that children showed an attention bias to cues signaling pain. Furthermore, children who were hypervigilant to pain cues benefitted from parents elaborating more about the pain experience, while children who avoided pain cues developed more negatively-biased pain memories if parents had a more elaborative style compared to a more evaluative parental style. In conclusion, this study suggests that optimal ways to talk about children's pain depend upon child characteristics (i.e., children's attention bias to pain).

The impact of maternal child- and self-oriented pain-related injustice appraisals upon maternal attention to child pain, attention to anger, and pain-attending behavior.

Objectives: The current study investigated the role of maternal child- and self-oriented injustice appraisals about child pain in understanding maternal attention for child pain and adult anger cues and pain-attending behavior. Methods: Forty-four children underwent a painful cold pressor task (CPT) while their mother observed. Eye tracking was used to measure maternal attention to child pain and adult anger cues. Initial attention allocation and attentional maintenance were indexed by probability of first fixation and gaze duration, respectively. Maternal pain-attending behaviors toward the child were videotaped and coded after CPT completion. Mothers also rated the intensity of pain and anger cues used in the free-viewing tasks. All analyses controlled for maternal catastrophizing about child pain. Results: Neither child-oriented nor self-oriented injustice was associated with maternal attentional bias toward child pain. Regarding attention toward self-relevant anger cues, differential associations were observed for self- and child-oriented injustice appraisals, with maternal self-oriented injustice being associated with a greater probability of first fixating on anger and with higher anger ratings, whereas maternal child-oriented injustice was associated with enhanced attentional maintenance toward anger. Neither type of maternal injustice appraisals was associated with maternal pain-attending behavior, which was only associated with maternal catastrophizing. Conclusions: The current study sheds light on potential differential mechanisms through which maternal self- vs. child-oriented injustice appraisals may exert their impact on parent and child pain-related outcomes. Theoretical implications and future directions are discussed.

The Effect of a Pain Educational Video Upon Child Pain-Related Memory and the Moderating Role of Parental Pain- and Non-Pain-Attending Verbalizations: An Experimental Lab-Based Study.

OBJECTIVES: Early memories of pain contribute to fear and may underlie the maintenance and development of chronic pain into adulthood. Accordingly, understanding determinants that may impact children's pain memory development is key. This study examined (a) the effect of a brief engaging pain educational video in healthy children before undergoing an experimental pain task upon children's recalled pain intensity and pain-related fear and (b) the moderating role of parental pain- and non-pain-attending verbalizations before and after the pain task. METHODS: Seventy-seven children (8-15 years old) participated in an experimental heat pain task, including actual heat pain stimuli delivered through a thermode on their forearm. Children were randomized to the experimental group (i.e., watching a pain educational video) or the control group (i.e., no video). Children's recalled pain intensity and pain-related fear were elicited 2 weeks later. RESULTS: Findings showed that recalled pain intensity (but not recalled pain-related fear) of children who watched the pain educational video was significantly lower compared to the control group (p = .028). Further, parental pain-attending verbalizations before the pain task moderated the impact of the video upon children's recalled pain intensity (p = .038). Specifically, children in the control group, but not the experimental group, whose parents used less pain-attending verbalizations recalled higher pain intensity, whereas children whose parents used more pain-attending verbalizations recalled lower pain intensity. CONCLUSIONS: As children's pain memories have important implications for pain assessment, treatment, and health across the lifespan, these findings might have important implications for the prevention of development or maintenance of maladaptive pain-related outcomes.

Validity and reliability of the Dutch version of the PedsQL™ 3.0 End Stage Renal Disease Module in children with chronic kidney disease in Belgium.

BACKGROUND: Children with chronic kidney disease (CKD) have a low quality of life (QoL). The PedsQL™ 4.0 Generic Core Scales are widely used to assess general QoL in children. The aim of this cross-sectional study was to translate the original version of the CKD-specific PedsQL™ 3.0 End Stage Renal Disease Module into a Dutch version and to evaluate its validity and reliability. METHODS: The forward-backward translation method based on the guidelines from the original developer was used to produce the Dutch version of the PedsQL™ 3.0 ESRD Module. Fifty-eight CKD patients (aged 8-18 years) and their parents (n = 31) filled in both generic and disease-specific modules. The non-clinical control group consisted of the same number of healthy children (matched for gender and age) and their parents. RESULTS: Cronbach's alpha coefficients (α's) for the PedsQL™ 3.0 ESRD Module demonstrated excellent reliability for the Total Scale scores. For all 7 subscales, α's were greater than 0.60, except for Perceived Physical Appearance. Overall, intercorrelations with the PedsQL™ 4.0 Generic Core Scales were in the medium to large range, supporting construct validity. Parent proxy reports showed lower generic QoL for all domains in CKD patients compared to healthy children. Child self-reports only demonstrated lower QoL on the domain School Functioning in children with CKD compared to healthy children. CONCLUSIONS: This study shows good validity and reliability for the Dutch version of the PedsQL™ 3.0 ESRD Module. However, testing with a larger study group is recommended in order to make final conclusions about the psychometric qualities of this measure. A higher resolution version of the Graphical abstract is available as Supplementary information.

The Impact of Parental Presence on Their Children During Painful Medical Procedures: A Systematic Review.

OBJECTIVE: Whether parental presence during their children's painful medical procedures is advantageous with regard to children's pain-related outcomes is questionable. Research on this topic is equivocal, and additional questions, such as whether levels of parental involvement may play a role as well, remain to be addressed. The purpose of this systematic review is to summarize and critically appraise the literature on the impact of parental presence vs absence during their children's painful medical procedures on the child's pain-related outcomes. METHODS: The review protocol was registered on Prospero (ID CRD42018116614). A systematic search in PubMed, Web of Science, and PsycArticles resulted in 22 eligible studies incorporating 2,157 participants. Studies were considered eligible if they included children (≤18 years old) undergoing a painful medical procedure and compared parental presence and/or involvement with parental absence during the procedure. RESULTS: The children's pain-related outcomes included self-reported pain intensity, self-reported fear, anxiety and distress, observed pain-related behavior, and physiological parameters. Overall, evidence points in the direction of beneficial effects of parental presence vs absence with regard to children's self-reported pain intensity and physiological parameters, whereas mixed findings were recorded for children's self-reported fears, anxiety and distress, and observed pain-related behaviors. CONCLUSIONS: To provide clear recommendations on how to involve the parent during the procedure, as well as for which type of children and parents parental presence has the best effects, further research is needed, as indicated in this review.

Racial disparities in observers' attention to and estimations of others' pain.

ABSTRACT: Research has demonstrated racial disparities in pain care such that Black patients often receive poorer pain care than White patients. Little is known about mechanisms accounting for the emergence of such disparities. The present study had 2 aims. First, we examined whether White observers' attentional processing of pain (using a visual search task [VST] indexing attentional engagement to and attentional disengagement from pain) and estimation of pain experience differed between White vs Black faces. Second, we examined whether these differences were moderated by (1) racially biased beliefs about pain experience and (2) the level of pain expressed by Black vs White faces. Participants consisted of 102 observers (87 females) who performed a VST assessing pain-related attention to White vs Black avatar pain faces. Participants also reported on racially biased beliefs about White vs Black individuals' pain experience and rated the pain intensities expressed by White and Black avatar faces. Results indicated facilitated attentional engagement towards Black (vs White) pain faces. Furthermore, observers who more strongly endorsed the belief that White individuals experience pain more easily than Black individuals had less difficulty disengaging from Black (vs White) pain faces. Regarding pain estimations, observers gave higher pain ratings to Black (vs White) faces expressing high pain and White (vs Black) faces expressing no pain. The current findings attest to the importance of future research into the role of observer attentional processing of sufferers' pain in understanding racial disparities in pain care. Theoretical and clinical implications are discussed, and future research directions are outlined.

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.

Use of Virtual Reality Distraction to Reduce Child Pain and Fear during Painful Medical Procedures in Children with Physical Disabilities in Uganda: A Feasibility Study.

OBJECTIVE: This study explored the acceptability and feasibility of the use of low-cost virtual reality (VR) glasses, and the Wong-Baker Faces Pain Scale and Children's Fear Scale scales, for pain and fear reduction in children admitted at the septic ward of CoRSU Rehabilitation Hospital in Uganda. METHODS: In total, 79 children aged 4-17 years of age were offered to watch cartoons using VR glasses while undergoing painful dressing procedures. Before and after the procedure, children were asked to index current pain; children and their caregivers were asked to rate anticipated fear. Focus group discussions with 13 children, 10 caregivers and 9 nurses explored acceptability and feasibility. Quantitative data were analyzed using STATA15, NVIVO12 was used for qualitative data analysis. RESULTS: The VR glasses were accepted by 76 (96%) of the children. Children, caregivers, and nurses mentioned the glasses were helpful in distracting children from the medical procedure and felt the use of the glasses helped reduce child fear and pain. Nurses felt it made their work easier. The Wong-Baker Faces Pain Scale was an acceptable and feasible method to measure pain, while the Children's Fear Scale was more difficult to interpret for our study population as they felt the faces on the scale were hard to read and identify with. CONCLUSIONS: The use of VR glasses may offer an acceptable and effective pain and fear reduction method in resource-constrained settings and should be further explored in a randomized controlled trial.

Mental Health Outcomes Among Parents of Children With a Chronic Disease During the COVID-19 Pandemic: The Role of Parental Burn-Out.

OBJECTIVE: The COVID-19 pandemic and associated quarantine measures highly impacted parental psychological well-being. Parents of children with chronic diseases might be specifically vulnerable as they already face multiple challenges to provide adequate care for their child. The research questions of the current study were twofold: (a) to examine whether parents of children with a chronic disease experienced more anxiety and depression compared to parents of healthy children and (b) to examine a series of risk factors for worsened well-being (i.e., depression, anxiety, and sleep problems), such as sociodemographic variables, COVID-19-specific variables (i.e., financial worries, living space, and perceived quality of health care), and parental psychological experiences (i.e., parental burn-out and less positive parenting experiences). METHODS: Parents of children with a chronic disease (i.e., the clinical sample; N = 599 and 507 for Research Questions 1 and 2, respectively) and parents of healthy children (i.e., the reference sample: N = 417) filled out an online survey. RESULTS: Findings demonstrated that the parents in the clinical sample reported higher levels of anxiety than parents in the reference sample. Analyses within the clinical sample indicated that COVID-19-specific stressors and parental psychological experiences were associated with higher levels of anxiety, depression, and sleep problems. Mediation analyses furthermore indicated that the association of COVID-19-specific stressors with all outcome measures was mediated by parental burn-out. CONCLUSIONS: Parents of children with a chronic disease constitute a vulnerable group for worse well-being during the current pandemic. Findings suggest interventions directly targeting parental burn-out are warranted.

The effect of a pain educational video intervention upon child pain-related outcomes: A randomized controlled study.

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.

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.

Pain-Related Injustice Appraisals in Youth with Sickle Cell Disease: A Preliminary Investigation.

OBJECTIVES: Sickle cell disease (SCD) is a genetic disorder that affects approximately 100,000 Americans, the majority of whom are African American. SCD-related pain often has deleterious effects on functioning and quality of life. The inherited nature of SCD, SCD-related stigma, and serious physical and functional impact of SCD-related pain create a situation ripe for individuals to appraise their SCD-related pain as unfair or unjust. The aim of this preliminary investigation is to explore the extent to which pediatric patients with SCD appraise their pain as unjust and how these appraisals relate to functioning. METHODS: Participants were youth with SCD (N = 30, mean age = 11.3, 57% boys) who attended a hematology clinic visit. Patients were invited to complete paper-based questionnaires assessing pain-related injustice appraisals, pain catastrophizing, pain and hurt, functional disability, depression, anxiety, and peer relationships. RESULTS: Results of hierarchical regressions indicate that pain-related injustice significantly predicted functional disability, depression, and anxiety after controlling for patient pain and catastrophizing. CONCLUSIONS: These findings suggest that pain-related injustice appraisals are an important contributor to the pain experience of youth with SCD. Early identification and remediation of pain-related injustice appraisals could have long-term functional benefits for youth with SCD.

The Impact of Parental Pain-attending and Non-pain-attending Responses on Child Pain Behavior in the Context of Cancer-related Painful Procedures: The Moderating Role of Parental Self-oriented Distress.

OBJECTIVES: Literature has demonstrated inconsistent findings regarding the impact of parental responses on child pain-related outcomes. Yet, research into factors that may underlie inconsistent findings regarding the variable impact of parental responses is lacking. The current study investigated the moderating role of parental distress in understanding the impact of parental pain-attending (eg, reassuring the child) and non-pain-attending (eg, distracting the child with humor) responses on child pain behavior (eg, crying). METHODS: Children (18 y and younger) with leukemia, undergoing a lumbar puncture (LP) and/or bone marrow aspiration procedure, and one of their parents, were recruited from the Pediatric Ghent University Hospital. Parent-child interactions were videotaped after the procedure allowing coding of parental responses and child pain behavior. Parents self-reported on experienced personal distress. RESULTS: Participants consisted of 42 children (24 boys, 18 girls) with leukemia and one of their parents. Children were 0.6 to 15 (7.08±4.39) years old. Findings indicated a positive association between parental pain-attending and child pain behavior, but only when parents reported high levels of distress (ß=0.56, P=0.001). No association was observed for parents reporting low levels of distress (ß=-0.09, ns). Parental non-pain-attending responses contributed to lower child pain behavior (ß=-0.24, P=0.045), independently of parental distress (ß=-0.07, ns). DISCUSSION: The current findings point to the moderating role of parental distress in understanding the impact of parental responses on child pain behavior and highlight the importance of interventions targeting parental emotion regulation to promote optimal child pain outcomes.

Child pain-related injustice appraisals mediate the relationship between just-world beliefs and pain-related functioning.

BACKGROUND: Research among adult and paediatric samples suggests that pain-related injustice appraisals contribute to adverse pain-related functioning. However, a singular focus on pain-related injustice appraisals carries the risk of underestimating the role of broader concepts of justice. This study examined the unique roles of child pain-related injustice appraisals and just-world beliefs in understanding disability and physical, emotional, social and academic functioning, as well as the mediating role of injustice appraisals in the relationship between just-world beliefs and functioning. METHODS: Participants comprised a school sample of 2,174 children (Study 1) and a clinical sample of 146 paediatric chronic pain patients (Study 2) who completed the Injustice Experience Questionnaire (IEQ), Personal and General Belief in a Just World scales (JWB-P/G), Functional Disability Inventory (FDI), Pain Catastrophizing Scale for Children (PCS-C) and Pediatric Quality of Life Inventory (PEDSQL). RESULTS: For both samples, child pain-related injustice appraisals were associated with poorer functioning, after controlling for just-world beliefs, catastrophizing, pain intensity, age and sex. In the school sample, injustice appraisals mediated the associations of both personal and general just-world beliefs with functioning. In the clinical sample, injustice appraisals mediated the association of personal, but not general, just-world beliefs with all functioning scales. CONCLUSIONS: The current findings attest to the unique role of pain-related injustice appraisals in understanding child pain-related functioning and their explanatory value in understanding the relationship between fundamental just-world beliefs and child pain-related functioning. SIGNIFICANCE: The present study adds to emerging literature on the adverse effects of child pain-related injustice appraisals in the context of pain, through showing that pain-related injustice appraisals are uniquely associated with pain-related functioning and mediate the relationship between just-world beliefs and pain-related functioning. These findings suggest that interventions may target pain-related injustice appraisals as a mechanism for change in children.

The time course of attentional biases in pain: a meta-analysis of eye-tracking studies.

ABSTRACT: Previous meta-analyses investigating attentional biases towards pain have used reaction time measures. Eye-tracking methods have been adopted to more directly and reliably assess biases, but this literature has not been synthesized in relation to pain. This meta-analysis aimed to investigate the nature and time course of attentional biases to pain-related stimuli in participants of all ages with and without chronic pain using eye-tracking studies and determine the role of task parameters and theoretically relevant moderators. After screening, 24 studies were included with a total sample of 1425 participants. Between-group analyses revealed no significant overall group differences for people with and without chronic pain on biases to pain-related stimuli. Results indicated significant attentional biases towards pain-related words or pictures across both groups on probability of first fixation (k = 21, g = 0.43, 95% confidence interval [CI] 0.15-0.71, P = 0.002), how long participants looked at each picture in the first 500 ms (500-ms epoch dwell: k = 5, g = 0.69, 95% CI 0.034-1.35, P = 0.039), and how long participants looked at each picture overall (total dwell time: k = 25, g = 0.44, 95% CI 0.15-0.72, P = 0.003). Follow-up analyses revealed significant attentional biases on probability of first fixation, latency to first fixation and dwell time for facial stimuli, and number of fixations for sensory word stimuli. Moderator analyses revealed substantial influence of task parameters and some influence of threat status and study quality. Findings support biases in both vigilance and attentional maintenance for pain-related stimuli but suggest attentional biases towards pain are ubiquitous and not related to pain status.
