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.

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 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 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.

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.

When, why, and how do People Deviate from Physical Distancing Measures During the COVID-19 Pandemic: A Mixed-Methods Study.

INTRODUCTION: To limit the spread of COVID-19, many countries, including Belgium, have installed physical distancing measures. Yet, adherence to these newly installed behavioral measures has been described as challenging and effortful. Based on the Health Action Process Approach (HAPA) model, this study performed an in-depth evaluation of when, why, and how people deviated from the physical distancing measures. METHODS: An online mixed-method study was conducted among Belgian adults (N = 2055) in the beginning of May 2020. Participants were recruited via an open call through email and social media platforms, using snowball sampling. Conditions wherein people deviated from the physical distancing measures were assessed by means of an open-ended question. HAPA determinants were assessed in a quantitative way. RESULTS: Half of the sample reported to deviate from the measures. Further, deviation from the measures was associated with each determinant outlined by the HAPA. Findings highlight that many people deviated from the measures because of their need for social contact. The majority of the people who deviated from the measures stated that they carefully weighed the risks of their behavior. CONCLUSIONS: Need for social contact pushed people to deviate from physical distancing measures in a deliberate manner. Potential areas for future interventions aimed at promoting adherence to physical distancing measures and enhancing psychosocial well-being are discussed.

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.

Adherence to the Physical Distancing Measures during the COVID-19 Pandemic: A HAPA-Based Perspective.

BACKGROUND: The COVID-19 pandemic requires massive and rapid behavior change. The Health Action Process Approach (HAPA) describes personal determinants that play a key role in behavior change. This study investigated whether these determinants are associated with adherence to physical distancing measures to prevent the spread of COVID-19 (i.e. keeping 1.5 m physical distance and staying at home). Decreased psychosocial well-being and lack of social support were explored as barriers to adherence. METHODS: Two cross-sectional surveys were conducted among adults in Belgium. The first survey (N = 2,379; March 2020) focused on adherence to physical distancing measures. The second survey (N = 805; April 2020) focused on difficulty with, and perseverance in, adhering to these measures. Linear regression models were fitted to examine associations with HAPA determinants, psychosocial well-being, and social support. RESULTS: Self-efficacy, outcome expectancies, intention, action planning, and coping planning were related to adhering to, difficulty with, and perseverance in, adhering to physical distancing measures. Decreased psychosocial well-being and lack of social support were related to more difficulties with adhering to physical distancing and lower perseverance. CONCLUSIONS: Health action process approach determinants are associated with adherence to physical distancing measures. Future work could design HAPA-based interventions to support people in adhering to these measures.

Parental (non-)pain attending verbalizations moderate the relationship between child attention and memory bias for pain.

BACKGROUND: Children's negatively biased pain-related memories (i.e. recalling pain as being more intense or fearful than initially reported) have been recognized as a key factor in explaining child pain development. While mechanisms underlying children's pain memory development remain poorly understood, attention biases and parent language have been implicated in conceptual models. This study examined the association between child pain-related attention and memory biases and the moderating role of parental pain and non-pain attending verbalizations. METHODS: Participants were 51 school children and one of their parents. Probability of initial fixation and gaze duration to pain were assessed using eye tracking methodology. Children performed a cold pressor task (CPT) and reported on experienced pain intensity and pain-related fear. A 3-minute parent-child interaction upon CPT completion allowed measurement of parental pain and non-pain attending verbalizations. Children's pain-related memories were elicited 2 weeks later. RESULTS: Findings indicated that the relationship between maintained attention to pain and fear memory bias was moderated by parental non-pain attending verbalizations such that higher gaze duration bias was positively associated with fear memory bias but only among children whose parents demonstrated low levels of non-pain attending verbalizations. The opposite pattern was observed for children whose parents showed high levels of non-pain attending verbalizations. No such effects were observed for child initial attention bias to pain, memory bias for pain and parental pain attending verbalizations. CONCLUSIONS: Findings highlight the importance of parental and child pain-related variables as well as their interaction in understanding negatively biased pain-related memories. SIGNIFICANCE: This study on child pain memories is the first to highlight that characteristics of the social context, such as parental (non-)pain-related verbalizations, as well as factors related to the intra-individual experience of pain, such as child attention bias to pain, should be studied jointly, as they interact with each other in their effect on the emergence of negatively biased memories of painful events.

Maternal food calling in domestic hens: influence of feeding context.

The aim of this study was to understand the relationship between production of food calls by maternal hens and food context. In a series of experiments with broody hens, we manipulated quality of items, quantity of food, food experience and dispersion of food items. We measured the frequency of food calling during standardized tests. Our results show that all the variables tested had significant effects on food calling. These results present some similarities and some discrepancies with previous reports on food calling by cockerels.

Mothering influences the distribution of activity in young domestic chicks.

The aim of this study was to determine whether the presence of a maternal hen influences the quality, quantity, and distribution of activity in young chicks. Brooded and nonbrooded chicks were observed during the entire light phase when they were 4 d of age. Our results revealed that although both brooded and nonbrooded chicks expressed the same behavioral items and in quite the same quantity, activity bouts were much longer in brooded chicks. However, only brooded chicks presented a high level of ultradian rhythmicity. Moreover, the brooded chicks made greater use of the space. The presence and the behavior of maternal hens appeared to provide structuring factors for the expression of the chicks behavior.
