The prevalence of chronic pain in children and adolescents: a systematic review update and meta-analysis.

ABSTRACT: Chronic pain, defined as persistent or recurring pain or pain lasting longer than 3 months, is a common childhood problem. The objective of this study was to conduct an updated systematic review and meta-analysis on the prevalence of chronic pain (ie, overall, headache, abdominal pain, back pain, musculoskeletal pain, multisite/general pain, and other) in children and adolescents. EMBASE, PubMed, CINAHL, and PsycINFO were searched for publications between January 1, 2009, and June 30, 2023. Studies reporting population-based estimates of chronic nondisease related pain prevalence in children or adolescents (age ≤ 19 years) were included. Two independent reviewers screened articles based on a priori protocol. One hundred nineteen studies with a total of 1,043,878 children (52.0% female, mean age 13.4 years [SD 2.4]) were included. Seventy different countries were represented, with the highest number of data points of prevalence estimates coming from Finland and Germany (n = 19 each, 4.3%). The overall prevalence of chronic pain in children and adolescents was 20.8%, with the highest prevalence for headache and musculoskeletal pain (25.7%). Overall, and for all types of pain except for back pain and musculoskeletal pain, there were significant differences in the prevalence between boys and girls, with girls having a higher prevalence of pain. There was high heterogeneity (I 2 99.9%). Overall risk of bias was low to moderate. In summary, approximately 1 in 5 children and adolescents experience chronic pain and prevalence varies by pain type; for most types, there is higher pain prevalence among girls than among boys. Findings echo and expand upon the systematic review conducted in 2011.

Quantitative sensory testing for assessment of somatosensory function in children and adolescents: a scoping review.

Quantitative sensory testing (QST) refers to a group of noninvasive psychophysical tests that examine responses to a range of calibrated mechanical and thermal stimuli. Quantitative sensory testing has been used extensively in adult pain research and has more recently been applied to pediatric pain research. The aims of this scoping review were to map the current state of the field, to identify gaps in the literature, and to inform directions for future research. Comprehensive searches were run in 5 databases. Titles, abstracts, and full texts were screened by 2 reviewers. Data related to the study aims were extracted and analyzed descriptively. A total of 16,894 unique studies were identified, of which 505 were screened for eligibility. After a full-text review, 301 studies were retained for analysis. Date of publication ranged from 1966 to 2023. However, the majority of studies (61%) were published within the last decade. Studies included participants across the developmental trajectory (ie, early childhood to adolescence) and most often included a combination of school-age children and adolescents (49%). Approximately 23% of studies were conducted in healthy samples. Most studies (71%) used only one QST modality. Only 14% of studies reported using a standardized QST protocol. Quantitative sensory testing in pediatric populations is an emerging and rapidly growing area of pain research. Future work is needed using comprehensive, standardized QST protocols to harness the full potential that this procedure can offer to our understanding of pediatric pain.

Preliminary development of a measure of parental behavioral responses to everyday pains in young children: the PREP.

Introduction: Everyday pains are experienced frequently by young children. Parent responses shape how young children learn about and experience pain. However, research on everyday pains in toddlers and preschoolers is scarce, and no self-report measures of parent responses to their child's pain exist for this age group. Objectives: The objective of this study was to develop a preliminary self-report measure of parent behavioral responses to everyday pains in the toddler and preschool years (the PREP) and examine its relationship with child age, sex, and parent and child distress. Methods: Items for the PREP were based on a behavioural checklist used in a past observational study of caregiver responses to toddler's everyday pains. Parents (N = 290; 93% mothers) of healthy children (47.9% boys) between 18 and 60 months (Mage = 34.98 months, SD = 11.88 months) completed an online survey of 46 initial PREP items, demographic characteristics, and their child's typical distress following everyday pains. An exploratory factor analysis was performed on the PREP items that describe observable actions parents may take in response to their young child's everyday pains. Results: The final solution included 10 items across 3 factors: Distract, Physical Soothe, and Extra Attention and explained 60% of the model variance. All PREP subscales were related to child distress; only Physical Soothe and Extra Attention were related to parent distress. Conclusion: This study was a preliminary step in the development and testing of a new self-report measure of parental responses to everyday pains during early childhood.

Understanding the unique and common perspectives of partners engaged in knowledge mobilization activities within pediatric pain management: a mixed methods study.

BACKGROUND: Knowledge mobilization (KM) is essential to close the longstanding evidence to practice gap in pediatric pain management. Engaging various partners (i.e., those with expertise in a given topic area) in KM is best practice; however, little is known about how different partners engage and collaborate on KM activities. This mixed-methods study aimed to understand what different KM partner groups (i.e., health professionals, researchers, and patient/caregiver partners) perceive as supporting KM activities within pediatric pain management. METHODS: This study used a convergent mixed-methods design. Ten partners from each of the three groups participated in interviews informed by the Consolidated Framework for Implementation Research, where they discussed what impacted KM activities within pediatric pain. Participants then rated and ranked select factors discussed in the interview. Transcripts were analyzed within each group using reflexive thematic analysis. Group-specific themes were then triangulated to identify convergence and divergence among groups. A matrix analysis was then conducted to generate meta-themes to describe overarching concepts. Quantitative data were analyzed using descriptive statistics. RESULTS: Unique themes were developed within each partner group and further analysis generated four meta-themes: (1) team dynamics; (2) role of leadership; (3) policy influence; (4) social influence. There was full agreement among groups on the meaning of team dynamics. While there was partial agreement on the role of leadership, groups differed on who they described as taking on leadership positions. There was also partial agreement on policy influence, where health professionals and researchers described different institutions as being responsible for providing funding support. Finally, there was partial agreement on social influence, where the role of networks was seen as serving distinct purposes to support KM. Quantitative analyses indicated that partner groups shared similar priorities (e.g., team relationships, communication quality) when it came to supporting KM in pediatric pain. CONCLUSIONS: While partners share many needs in common, there is also nuance in how they wish to be engaged in KM activities as well as the contexts in which they work. Strategies must be introduced to address these nuances to promote effective engagement in KM to increase the impact of evidence in pediatric pain.

The #SeePainMoreClearly Phase II Pain in Dementia Social Media Campaign: Implementation and Evaluation Study.

BACKGROUND: Social media platforms have been effective in raising awareness of the underassessment and undertreatment of pain in dementia. OBJECTIVE: After a successful pilot campaign, we aimed to scale our pain-in-dementia knowledge mobilization pilot initiative (ie, #SeePainMoreClearly) to several social media platforms with the aid of a digital media partner. The goal of the initiative was to increase awareness of the challenges in the assessment and management of pain among people with dementia. A variety of metrics were implemented to evaluate the effort. Through this work, we endeavored to highlight key differences between our pilot initiative (which was a grassroots initiative), focusing largely on Twitter and YouTube, and the current science-media partnership. We also aimed to generate recommendations suitable for other social media campaigns related to health or aging. METHODS: Evidence-based information about pain in dementia was summarized into engaging content (eg, videos) tailored to the needs of various knowledge users (eg, health professionals, families, and policy makers). We disseminated information using Facebook (Meta Platforms), Twitter (X Corp), YouTube (Alphabet Inc), Instagram (Meta Platforms), and LinkedIn (LinkedIn Corp) and measured the success of the initiative over a 12-month period (2020 to 2021). The evaluation methods focused on web analytics and questionnaires related to social media content. Knowledge users' web responses about the initiative and semistructured interviews were analyzed using thematic analysis. RESULTS: During the course of the campaign, >700 posts were shared across all platforms. Web analytics showed that we drew >60,000 users from 82 countries to our resource website. Of the social media platforms used, Facebook was the most effective in reaching knowledge users (ie, over 1,300,000 users). Questionnaire responses from users were favorable; interview responses indicated that the information shared throughout the initiative increased awareness of the problem of pain in dementia and influenced respondent behavior. CONCLUSIONS: In this investigation, we demonstrated success in directing knowledge users to a resource website with practical information that health professionals could use in patient care along with pain assessment and management information for caregivers and people living with dementia. The evaluation metrics suggested no considerable differences between our pilot campaign and broader initiative when accounting for the length of time of each initiative. The limitations of large-scale health campaigns were noted, and recommendations were outlined for other researchers aiming to leverage social media as a knowledge mobilization tool.

Patient engagement in designing, conducting, and disseminating clinical pain research: IMMPACT recommended considerations.

ABSTRACT: In the traditional clinical research model, patients are typically involved only as participants. However, there has been a shift in recent years highlighting the value and contributions that patients bring as members of the research team, across the clinical research lifecycle. It is becoming increasingly evident that to develop research that is both meaningful to people who have the targeted condition and is feasible, there are important benefits of involving patients in the planning, conduct, and dissemination of research from its earliest stages. In fact, research funders and regulatory agencies are now explicitly encouraging, and sometimes requiring, that patients are engaged as partners in research. Although this approach has become commonplace in some fields of clinical research, it remains the exception in clinical pain research. As such, the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials convened a meeting with patient partners and international representatives from academia, patient advocacy groups, government regulatory agencies, research funding organizations, academic journals, and the biopharmaceutical industry to develop consensus recommendations for advancing patient engagement in all stages of clinical pain research in an effective and purposeful manner. This article summarizes the results of this meeting and offers considerations for meaningful and authentic engagement of patient partners in clinical pain research, including recommendations for representation, timing, continuous engagement, measurement, reporting, and research dissemination.

A Randomized Controlled Trial of a Parent-Led Memory-Reframing Intervention to Reduce Distress and Pain Associated with Vaccine Injections in Young Children.

Children remember their memories of pain long after the painful experience is over. Those memories predict higher levels of future pain intensity. Young children's memories can be reframed to be less distressing. Parents and the way they reminisce about past events with their children play a key role in the formation of pain memories. A novel parent-led memory-reframing intervention changed children's memories of post-surgical pain to be less distressing. The intervention efficacy in the context of vaccine injections is unclear. This registered randomized controlled trial (NCT05217563) aimed to fill this gap. Seventy-four children aged 4.49 years (SD = 1.05) and scheduled to obtain two COVID-19 vaccine injections and one of their parents were randomized to receive: (1) standard care; (2) standard care and memory-reframing information; and (3) standard care and memory-reframing information with verbal instructions. Children reported their pain after vaccine injections. One week after the first vaccination, children reported memory of pain. Parents reported their use of memory-reframing strategies and intervention feasibility and acceptability. The intervention did not result in significant differences in children's recalled or future pain. Parents rated the intervention as acceptable and feasible.

A systematic review of the psychosocial factors associated with pain in children with juvenile idiopathic arthritis.

BACKGROUND: Pain is one of the most frequently reported experiences amongst children with Juvenile Idiopathic Arthritis (JIA); however, the management of JIA pain remains challenging. As pain is a multidimensional experience that is influenced by biological, psychological, and social factors, the key to effective pain management lies in understanding these complex relationships. The objective of this study is to systematically review the literature on psychosocial factors of children with JIA and their caregivers 1) associated with and 2) predictive of later JIA pain intensity, frequency, and sensitivity in children 0-17 years of age. METHODS: The Joanna Briggs Institute methodology for etiology and risk and Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement guided the conduct and reporting of this review. Terms related to pain and JIA were searched in English without date restrictions across various databases (PubMed, CINAHL, PsycINFO, Embase, Scopus, and the Cochrane Central Register of Controlled Trials) in September 2021. Two independent reviewers identified, extracted data from, and critically appraised the included studies. Conflicts were resolved via consensus. RESULTS: Of the 9,929 unique studies identified, 61 were included in this review and reported on 516 associations. Results were heterogeneous, likely due to methodological differences and moderate study quality. Results identified predominantly significant associations between pain and primary and secondary appraisals (e.g., more child pain beliefs, lower parent/child self-efficacy, lower child social functioning), parent/child internalizing symptoms, and lower child well-being and health-related quality of life. Prognostically, studies had 1-to-60-month follow-up periods. Fewer beliefs of harm, disability, and no control were associated with lower pain at follow-up, whereas internalizing symptoms and lower well-being were predictive of higher pain at follow-up (bidirectional relationships were also identified). CONCLUSIONS: Despite the heterogeneous results, this review highlights important associations between psychosocial factors and JIA pain. Clinically, this information supports an interdisciplinary approach to pain management, informs the role of psychosocial supports, and provides information to better optimize JIA pain assessments and interventions. It also identifies a need for high quality studies with larger samples and more complex and longitudinal analyses to understand factors that impact the pain experience in children with JIA.

The Relationship Between Chronic Pain, Depression, Psychosocial Factors, and Suicidality in Adolescents.

BACKGROUND: Chronic pain in youth is often associated with social conflict, depression, and suicidality. The interpersonal theory of suicide posits that there are psychosocial factors, such as peer victimization and lack of fear of pain, that may also influence suicidality. OBJECTIVES: The objective of this study was to determine whether depressive symptoms, peer victimization, and lack of fear of pain predict suicidality in adolescents with chronic pain. It was hypothesized that higher levels of depressive symptoms and peer victimization, and lower levels of fear of pain, would predict a higher lifetime prevalence of suicidality. METHODS: Participants consisted of 184 youth with primary chronic pain conditions (10 to 18 y, M = 14.27 y). Measures included diagnostic clinical interviews assessing suicidality and self-report questionnaires assessing depressive symptoms, peer victimization, and fear of pain. RESULTS: Forty-two (22.8%) participants reported suicidality. Regression analyses demonstrated that the occurrence of suicidality was associated with higher rates of depressive symptoms (ß = 1.03, P = 0.020, 95% CI: 1.01, 1.06) and peer victimization (ß = 2.23, P < 0.05, 95% CI: 1.07, 4.63), though there was no association between lower fear of pain and suicidality. DISCUSSION: These results suggest that depressive symptoms and peer victimization are significant predictors of suicidality in adolescents with chronic pain; however, lower fear of pain was not shown to be a significant predictor. Given these findings, depression and peer victimization should be further explored and considered in the design and implementation of prevention and early intervention strategies that target chronic pain and suicidality in youth.

Patient Responses to the Term Pain Catastrophizing: Thematic Analysis of Cross-sectional International Data.

Pain catastrophizing is understood as a negative cognitive and emotional response to pain. Researchers, advocates and patients have reported stigmatizing effects of the term in clinical settings and the media. We conducted an international study to investigate patient perspectives on the term pain catastrophizing. Open-ended electronic patient and caregiver proxy surveys were promoted internationally by collaborator stakeholders and through social media. 3,521 surveys were received from 47 countries (77.3% from the U.S.). The sample was mainly female (82.1%), with a mean age of 41.62 (SD 12.03) years; 95% reported ongoing pain and pain duration > 10 years (68.4%). Forty-five percent (n = 1,295) had heard of the term pain catastrophizing; 12% (n = 349) reported being described as a 'pain catastrophizer' by a clinician with associated high levels of feeling blamed, judged, and dismissed. We present qualitative thematic data analytics for responses to open-ended questions, with 32% of responses highlighting the problematic nature of the term. We present the patients' perspective on the term pain catastrophizing, its material effect on clinical experiences, and associations with negative gender stereotypes. Use of patient-centered terminology may be important for favorably shaping the social context of patients' experience of pain and pain care. PERSPECTIVE: Our international patient survey found that 45% had heard of the term pain catastrophizing, about one-third spontaneously rated the term as problematic, and 12% reported the term was applied to them with most stating this was a negative experience. Clinician education on patient-centered terminology may improve care and reduce stigma.

Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks-American Pain Society-American Academy of Pain Medicine Pain Taxonomy Diagnostic Criteria for Acute Needle Pain.

Needle procedures are among the most common causes of pain and distress for individuals seeking health care. While needle pain is especially problematic for children needle pain and associated fear also has significant impact on adults and can lead to avoidance of appropriate medical care. Currently there is not a standard definition of needle pain. A taxonomy, or classification system, for acute needle pain would aid research efforts and enhance clinical care. To meet this need, the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks public-private partnership with the U.S. Food and Drug Administration, the American Pain Society, and the American Academy of Pain Medicine formed the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks-American Pain Society-American Academy of Pain Medicine Pain Taxonomy initiative. One of the goals of this initiative was to develop taxonomies for acute pain disorders, including needle pain. To accomplish this, a working group of experts in needle pain was convened. Based on available literature and expert opinion, the working group used a 5-dimenional structure (diagnostic criteria, common features, modulating factors, impact and/or functional consequences, and putative mechanisms) to develop an acute pain taxonomy that is specific needle pain. As part of this, a set of 4 diagnostic criteria, with 2 modifiers to account for the influence of needle associated fear, are proposed to define the types of acute needle pain. PERSPECTIVE: This article presents a taxonomy for acute needle pain. This taxonomy could help to standardize definitions of acute pain in clinical studies of patients undergoing needle procedures.

A Brief Mindfulness Intervention for Parents and Children before Pediatric Venipuncture: A Randomized Controlled Trial.

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.

A multicentre Canadian survey of caregiver perspectives on COVID vaccine-related pain and stress for their family.

Background: Caregiver hesitancy for their children to receive the COVID-19 vaccine remains due to concerns regarding safety and efficacy, but also due to fear of vaccine administration-related pain and distress. Study objectives were to determine caregivers' perceptions regarding both their personal and child's COVID-19 vaccine administration-related stress and fear and relate this to their likelihood to allow their child to receive COVID-19 vaccinations. Methods: This study was a secondary data analysis of a multicentre, cross-sectional survey of caregivers presenting to four Canadian pediatric emergency departments. Caregivers were surveyed between December 2020 and March 2021 and completed a digital survey on their own smartphones. Results: 331 caregivers responded to the survey (mean age 39.9 years [SD 7.71]); 74.2% (245/331) were mothers. Children's mean age was 8.8 years [SD 5.4]; 49.8% (165/331) were female. 64.1% (209/326) of caregivers were willing to vaccinate their child against COVID-19, while 35.9% (117/326) were not. Greater perceived COVID-19 vaccine administration-related pain (0.88 [0.80; 0.95], p = .003) and stress (0.82 [0.76; 0.89], p = <.001) for their child as well as greater perceived personal stress with their own COVID-19 vaccine administration (0.81 [0.75; 0.88], p = <.001) were associated with caregivers being less likely to vaccinate their child. Conclusions: During the time period between COVID-19 pandemic waves 2 and 3, and after the vaccine had been federally approved for adults, one-third of Canadian caregivers surveyed reported being unwilling to vaccinate their child against COVID-19 in the future. Managing children's and caregivers' vaccine administration-related fear and stress may improve vaccine uptake for children.

The State of Patient Engagement among Pain Research Trainees in Canada: Results of a National Web-Based Survey.

Background: Patient engagement (PE) in research refers to partnering with people with lived experience (e.g., patients, caregivers, family) as collaborators in the research process. Although PE is increasingly being recognized as an important aspect of health research, the current state of PE among pain research trainees in Canada is unclear. Aims: The aims of this study were to describe perspectives about and experiences with PE among trainees conducting pain research in Canada, to identify perceived barriers and facilitators, and to describe recommendations to improve its implementation. Methods: A cross-sectional web-based survey (English and French) was administered to trainees at any level conducting pain research at any Canadian academic institution. Results: A total of 128 responses were received; 115 responses were complete and included in the final analysis. The majority of respondents identified as women (90/115; 78.3%), in graduate school (83/115; 72.2%), and conducting clinical pain research (83/115; 72.2%). Most respondents (103/115; 89.6%) indicated that PE is "very" or "extremely" important. Despite this, only a minority of respondents (23/111; 20.7%) indicated that they "often" or "always" implement PE within their own research. The most common barrier identified was lack of knowledge regarding the practical implementation of PE, and understanding its positive value was the most commonly reported facilitator. Recommendations for improving the implementation of PE were diverse. Conclusions: Despite viewing PE as important in research, a minority of pain research trainees regularly implement PE. Results highlight perceived barriers and facilitators to PE and provide insight to inform the development of future training and other enabling initiatives.

Contexte: L'engagement des patients dans la recherche fait référence au partenariat avec des personnes ayant une expérience vécue (p. ex. des patients, des soignants ou des membres de la famille) en tant que collaborateurs dans le processus de recherche. Bien que l'engagement des patients soit de plus en plus reconnu comme un aspect important de la recherche en santé, son état actuel chez les stagiaires en recherche sur la douleur au Canada n'est pas clair.Objectif: Les objectifs de cette étude étaient de décrire les points de vue et les expériences sur l'engagement des patients chez les stagiaires menant des études sur la douleur au Canada, de recenser les obstacles et les facilitateurs perçus et de formuler des recommandations pour améliorer sa mise en œuvre.Méthodes: Une enquête transversale sur le Web (en anglais et en français) a été menée auprès des stagiaires de tout niveau menant des études sur la douleur dans n'importe quel établissement universitaire canadien.Résultats: Au total, 128 réponses ont été reçues; 115 réponses étaient complètes et ont été incluses dans l'analyse finale. La majorité des répondants ont indiqué qu'elles étaient des femmes (90/115; 78,3 %), qu'elles étaient inscrites aux cycles supérieures (83/115 ; 72,2 %) et qu'elles effectuaient des études cliniques sur la douleur (83/115 ; 72,2 %). La plupart des répondants (103/115 ; 89,6 %) ont indiqué que l'engagement était « très ¼ ou « extrêmement ¼ important. Malgré cela, seule une minorité de répondants (23/111; 20,7 %) ont indiqué qu'ils mettaient en œuvre l'engagement des patients « souvent ¼ ou « toujours ¼ dans leur propre recherche. L'obstacle le plus fréquemment énoncé était le manque de connaissances concernant la mise en œuvre pratique de l'engagement des patients, et la compréhension de sa valeur positive était le facilitateur le plus souvent signalé. Les recommandations visant à améliorer la mise en œuvre de l'engagement des patients étaient diverses.Conclusions: Bien que l'engagement des patients soit considéré comme important dans la recherche, une minorité de stagiaires en recherche sur la douleur le mettent régulièrement en œuvre. Les résultats mettent en évidence les obstacles et les facilitateurs perçus pour l'engagement des patients et fournissent un aperçu pour éclairer l'élaboration de la formation future et d'autres initiatives habilitantes.

Pain and Fear of Cancer Recurrence in Survivors of Childhood Cancer.

OBJECTIVES: Theoretical models suggest that anxiety, pain intensity, and pain catastrophizing are implicated in a cycle that leads to heightened fear of cancer recurrence (FCR). However, these relationships have not been empirically examined. The objective of this study was to examine the relationships between anxiety symptoms, pain intensity, pain catastrophizing, and FCR in childhood cancer survivors and their parents and to examine whether pain catastrophizing predicts increased FCR beyond anxiety symptoms and pain intensity. METHODS: The participants were 54 survivors of various childhood cancers (Mage=13.1 y, range=8.4 to 17.9 y, 50% female) and their parents (94% mothers). Children reported on their pain intensity in the past 7 days. Children and parents separately completed measures of anxiety symptoms, pain catastrophizing, and FCR. RESULTS: Higher anxiety symptoms were associated with increased pain intensity, pain catastrophizing, and FCR in childhood cancer survivors. Higher anxiety symptoms and pain catastrophizing, but not child pain intensity, were associated with FCR in parents. Hierarchical linear regression models revealed that pain catastrophizing explained unique variance in both parent (ΔR2=0.11, P<0.01) and child (ΔR2=0.07, P<0.05) FCR over and above the effects of their own anxiety symptoms and child pain. DISCUSSION: The results of this study provides novel data on the association between pain and FCR and suggests that a catastrophic style of thinking about pain is more closely related to heightened FCR than one's anxiety symptoms or the sensory pain experience in both childhood cancer survivors and their parents. Pain catastrophizing may be a novel intervention target for survivors and parents struggling with fears of recurrence.

Pain burden in children with cerebral palsy (CPPain) survey: Study protocol.

Pain is a significant health concern for children living with cerebral palsy (CP). There are no population-level or large-scale multi-national datasets using common measures characterizing pain experience and interference (ie, pain burden) and management practices for children with CP. The aim of the CPPain survey is to generate a comprehensive understanding of pain burden and current management of pain to change clinical practice in CP. The CPPain survey is a comprehensive cross-sectional study. Researchers plan to recruit approximately 1400 children with CP (primary participants) across several countries over 6-12 months using multimodal recruitment strategies. Data will be collected from parents or guardians of children with CP (0-17 years) and from children with CP (8-17 years) who are able to self-report. Siblings (12-17 years) will be invited to participate as controls. The CPPain survey consists of previously validated and study-specific questionnaires addressing demographic and diagnostic information, pain experience, pain management, pain interference, pain coping, activity and participation in everyday life, nutritional status, mental health, health-related quality of life, and the effect of the COVID-19 pandemic on pain and access to pain care. The survey will be distributed primarily online. Data will be analyzed using appropriate statistical methods for comparing groups. Stratification will be used to investigate subgroups, and analyses will be adjusted for appropriate sociodemographic variables. The Norwegian Regional Committee for Medical and Health Research Ethics and the Research Ethics Board at the University of Minnesota in USA have approved the study. Ethics approval in Canada, Sweden, and Finland is pending. In addition to dissemination through peer-reviewed journals and conferences, findings will be communicated through the CPPain Web site (www.sthf.no/cppain), Web sites directed toward users or clinicians, social media, special interest groups, stakeholder engagement activities, articles in user organization journals, and presentations in public media.

Pain management communication between parents and nurses after pediatric outpatient surgery.

PURPOSE: The purpose of this study was to explore parent-nurse pain management communication during a child's discharge process following pediatric outpatient surgery. DESIGN AND METHODS: Thirty-two clinical encounters at discharge between parents (N = 40) and nurses (N = 25) at BC Children's Hospital were audio recorded and transcribed verbatim. Content analysis was applied on the audio recordings and corresponding transcripts using MAXQDA qualitative research software and Microsoft Excel. RESULTS: Overall, nurses delivered pain management instructions at an average sixth grade readability level and frequently used communication elements of reassurance, optimism, and question-asking. Less consistent communication elements included open-ended questions, interruptions, and promotion of parental decision-making. Parents most frequently asked one to five questions, with pain medication being the most inquired topic. CONCLUSIONS: Several strengths of the nurse communication approach were identified, and parent questions highlighted a need for greater understanding around pain medication. PRACTICE IMPLICATIONS: These findings will help guide effective pain management communication and care for young patients and their families.

The Pain Coping Questionnaire short-form: preliminary reliability and validity.

INTRODUCTION: The Pain Coping Questionnaire (PCQ) has support for its validity and reliability as a tool to understand how a child copes with pain of an extended duration. However, measure length may limit feasibility in clinical settings. OBJECTIVES: The primary goal of this study was to develop a short-form (PCQ-SF) that could be used for screening how children cope with chronic or recurrent pain and examine its reliability and validity. METHODS: The PCQ-SF was developed in a stepwise manner. First, a confirmatory factor analysis was computed using an amalgamated data set from the validation studies of the PCQ (N = 1225). Next, ratings from researchers and clinicians were obtained on PCQ item content and clarity (n = 12). Finally, the resulting 16-item short-form was tested in a pediatric sample living with chronic and recurrent pain (65 parent-child dyads; n = 128). RESULTS: The PCQ-SF has acceptable preliminary reliability and validity. Both statistical and expert analyses support the collective use of the 16 items as an alternative to the full measure. CONCLUSIONS: The compact format of the PCQ-SF will allow practitioners in high-volume clinical environments to quickly determine a child's areas of strengths and weaknesses when coping with pain. Future research using larger more diverse samples to confirm clinical validity is warranted.

Measuring fear of cancer recurrence in survivors of childhood cancer: Development and preliminary validation of the Fear of Cancer Recurrence Inventory (FCRI)-Child and Parent versions.

OBJECTIVE: Fear of cancer recurrence (FCR) is a common and distressing psychosocial concern for adult cancer survivors. Data on this construct in child survivors is limited and there are no validated measures for this population. This study aimed to adapt the Fear of Cancer Recurrence Inventory-Short Form (FCRI-SF) for survivors of childhood cancer aged 8-18 years (Fear of Cancer Recurrence Inventory-Child version [FCRI-C]) and their parents (Fear of Cancer Recurrence Inventory-Parent version [FCRI-P]) to self-report on their own FCR and to examine the initial psychometric properties. METHODS: The FCRI-SF was adapted through expert panel input and cognitive interviews with child survivors <18 years. The factor structure, internal consistency and construct and criterion validity of the FCRI-C and FCRI-P were examined in 124 survivors of childhood cancer (43% female; Mage  = 14.58 years, SD = 2.90) and 106 parents (90% mothers). RESULTS: All FCRI-SF items were retained for the FCRI-C with simplified language. The internal consistencies of the FCRI-C (α = 0.88) and FCRI-P (α = 0.83) were good. Exploratory factor analyses yielded one-factor structures for both measures. Higher scores on the FCRI-C and FCRI-P were associated with greater intolerance of uncertainty and pain catastrophizing. Higher child FCR was also related to more hypervigilance to bodily symptoms. Parents with higher FCR reported contacting their child's doctors and nurses and scheduling medical appointments for their child more frequently. Children reported significantly lower FCR compared to parents. CONCLUSIONS: The FCRI-C and FCRI-P demonstrated strong reliability and preliminary validity. This study offers preliminary data to support the use of the FCRI-C and FCRI-P to measure FCR in survivors of childhood cancer aged 8-18 years and their parents.
