A Child's Concept of Pain: An International Survey of Pediatric Pain Experts

Developing and assessing the measurement properties of an instrument to assess the impact of musculoskeletal pain in children aged 9 to 12-the pediatric musculoskeletal pain impact summary score

BACKGROUND

Despite the high prevalence of musculoskeletal (MSK) pain in children, there is a lack of instruments to measure the impact of MSK pain on children's activity and participation.

OBJECTIVE

To assess the reliability and construct validity of the Pediatric MSK Pain Impact summary score in school children (aged 9 to 12) with MSK pain.

METHODS

We used a pragmatic approach in a reflective framework to assess internal consistency, structural validity, convergent validity, and discriminative validity in a sample of 615 children with MSK pain.

RESULTS

The confirmatory factor analysis results indicate that the summary score has limited internal consistency and construct validity. The estimated Cronbach's alpha was 0.63, and most goodness of fit indices met the recommended thresholds (SRMR = 0.030; GFI = 0.993, CFI = 0.955, RMSEA 0.073), although they were close to the lower bounds of the thresholds. The convergent validity showed appropriate correlation of the summary score with quality of life (r = -0.33), care-seeking (r = 0.45), and medication intake (r = 0.37). Discriminative validity showed that the instrument can discriminate between the impact of pain on children with frequent and infrequent (2.93; 95% CI: 2.36 - 3.50) MSK pain.

CONCLUSION

The Pediatric MSK Pain Impact summary showed limited internal consistency and construct validity; however, it can discriminate between children with frequent and infrequent pain. The results are promising for clinical and research practices as it is a short and convenient tool to be used in school-aged children.

Assessing healthcare professionals' perceptions of pain concepts and beliefs

BACKGROUND

Healthcare professionals deliver pain education, yet their perception of pain experiences is not well understood, which can affect their interactions with patients in pain.

OBJECTIVE

This study explored Korean healthcare professionals' perceptions of the usefulness of assessing pain concepts and beliefs and the importance of domains identified in the pain literature.

METHODS

This descriptive cross-sectional study employed an online survey administered to nurses, physical therapists, and physicians, including the Neurophysiology of Pain Questionnaire, Tampa Scale for Kinesiophobia, and related optional open-ended questions.

RESULTS

Most participants acknowledged the importance and usefulness of assessing understanding of pain concepts but anticipated patients' difficulty comprehending items assessing biological mechanisms underlying pain. Participants questioned the items' accuracy, indicating their limited pain knowledge and the necessity of reducing literacy demands. The critical domains of pain education were learning about pain, external factors influencing pain, and pain as a form of protection.

CONCLUSION

Participants had suboptimal pain knowledge but emphasized decreasing literacy demands of pain neurophysiology items. Additionally, it is necessary to develop and implement a pain education program to improve pain-related knowledge and provide educational content for healthcare professionals encountering patients in pain.

Narrative Review of the Complex Interaction between Pain and Trauma in Children: A Focus on Biological Memory, Preclinical Data, and Epigenetic Processes

The incidence and collective impact of early adverse experiences, trauma, and pain continue to increase. This underscores the urgent need for translational efforts between clinical and preclinical research to better understand the underlying mechanisms and develop effective therapeutic approaches. As our understanding of these issues improves from studies in children and adolescents, we can create more precise preclinical models and ultimately translate our findings back to clinical practice. A multidisciplinary approach is essential for addressing the complex and wide-ranging effects of these experiences on individuals and society. This narrative review aims to (1) define pain and trauma experiences in childhood and adolescents, (2) discuss the relationship between pain and trauma, (3) consider the role of biological memory, (4) decipher the relationship between pain and trauma using preclinical data, and (5) examine the role of the environment by introducing the importance of epigenetic processes. The ultimate scope is to better understand the wide-ranging effects of trauma, abuse, and chronic pain on children and adolescents, how they occur, and how to prevent or mitigate their effects and develop effective treatment strategies that address both the underlying causes and the associated physiological and psychological effects.

Know Pain, No Pain? Preliminary Testing and Application of a New Tool to Assess Biopsychosocial Pain Concepts in Children

To deliver tailored pain science education, assessing children's biopsychosocial pain concepts is necessary. As validated tools are lacking, a new tool is presented, the biopsychosocial pain concept matrix (BiPS matrix), which assesses children's biological, psychological, and social pain concepts in five domains according to the Common-Sense Model of Self-Regulation (Hagger and Orbell, 2003): (1) illness identity, (2) causes, (3) consequences, (4) duration, and (5) treatment. The present preliminary study aims to (1) assess the items' readability and understandability in cognitive interviews with N = 9 healthy children (9 to 19 years, M = 13.78 years, SD = 3.05; 44% female) and (2) pre-test the BiPS matrix within an online survey of N = 27 healthy children (9 to 19 years, M = 13.76 years, SD = 3.03; 56% female). Results revealed difficulties in understanding some items. Children's understanding increased with age. Age, chronic pain status, and pain in the social environment were positively associated with the BiPS total score, whereas the latter explained the most variance in pain concepts of children. Patient-focused methods such as cognitive interviews proved essential in testing the readability and understanding of items in children. Future studies are warranted to further validate the BiPS matrix.

The concept of pain inventory for children: The reliability and validity study of the Turkish version

BACKGROUND AND PURPOSE

Pain experiences in childhood are very likely to be reflected in adulthood. The early evaluation of the concept of pain in children may eventually lead to. better patient outcomes in the future. Therefore, we aimed to culturally and developmentally adapt the Concept of Pain Inventory for Children (COPI) for Turkish children.

METHODS

This descriptive, correlational study was conducted with 239 post-operative children aged 8-12 years between June and December 2021. The research adhered to COSMIN guidelines. The data were collected using a descriptive information form and the COPI. Factor analysis, Cronbach's alpha, and item-total score analysis were used for the data analysis.

RESULTS

The resulting unidimensional scale consists of 12 items in Turkish. The scale explained 65% of the total variance. The exploratory factor analysis showed that the factor loadings of items ranged from 0.64 to 0.91. The confirmatory factor analysis showed that the factor loadings of items ranged from 0.66 to 0.92. Goodness of fit indexes were found to be as follows: Normed Fit Index >0.90; Incremental Fit Index >0.90; Comparative Fit Index >0.90; and the Root Mean Square Error of Approximation <0.08. The total Cronbach's alpha coefficient of the scale was 0.78 (reliable).

CONCLUSIONS

The 12-item Turkish translation of the COPI was deemed valid and reliable in 8-12-year-old children in a post-operative setting.

PRACTICE IMPLICATIONS

Evaluation of children's pain concepts during childhood may contribute to the identification of conceptual gaps for pain science education.

The Concept of Pain Inventory for Adults (COPI-Adult): Assessing Knowledge and Beliefs Regarding Pain Science Education

OBJECTIVES

Assessing knowledge and beliefs regarding pain science can identify gaps and misconceptions. The Concept of Pain Inventory (COPI) was recently developed in children with the intent to guide targeted pain science education. We utilized the original COPI item pool to (1) develop a tool to assess an adult's concept of pain in a cohort who had not received pain science education, (2) evaluate its psychometric properties, (3) examine distribution of scores in a cohort of adults who had received pain science education, and (4) examine associations between scores and clinical variables.

MATERIALS AND METHODS

A total cohort of 627 adults were recruited through social media for an online survey. Initial development was conducted on those who had not received prior pain science education (n=125), then the COPI-Adult tool was tested in those who had received prior pain science education (n=502).

RESULTS

The resulting unidimensional 13-item COPI-Adult had acceptable internal consistency (α=0.78) and good test-retest reliability at 1 week (Intraclass Correlation Coefficient3,1=0.84 (95% confidence interval: 0.71-0.91). Higher COPI-Adult scores reflect greater alignment with contemporary pain science. COPI-Adult scores were correlated with revised Neurophysiology of Pain Questionnaire (rNPQ) scores and inversely correlated with average and current pain intensity, and pain interference. Adults who reported having received pain science education had significantly higher mean COPI-Adult scores than those who had not, and this difference exceeded the smallest detectable change.

DISCUSSION

The COPI-Adult is a brief questionnaire with promising psychometric properties to identify conceptual gaps or misconceptions to inform individualized pain science education.

Integrative pediatric pain management: Impact & implications of a novel interdisciplinary curriculum

OBJECTIVES

Objectives of this paper are to: 1) Describe a novel interdisciplinary, integrative pain curriculum for pediatric residents. 2) Describe changes in residents' understanding of pain epidemiology, physiology, and management; application of the biopsychosocial model in pain management; and understanding and application of non-pharmacologic approaches to pain management.

DESIGN, SETTING

This study was done in a pediatric residency program within an urban pediatric teaching hospital. It employed both anonymous, Likert-scale surveys administered via Qualtrics, as well as open-ended, free response questions.

INTERVENTIONS

We provided a multidisciplinary pain education curriculum to pediatric residents with a focus on pain neuroscience, a history of pain management, the biopsychosocial model of care, and exposure to non-pharmacologic interventions to pain management over six hours of instruction conducted in two blocks of three hours each.

OUTCOME MEASURES

Self-identified changes via survey measuring resident physician knowledge, comfort, approach, and management of pediatric pain through an interdisciplinary pain curriculum.

RESULTS

Prior to this training, many residents were not confident in their understanding of pain neuroscience, the biopsychosocial model of care, and non-pharmacologic interventions. At completion of training, residents indicated positive changes in knowledge of, and comfort with, all of the domains taught. Ninety percent of residents indicated that the curriculum changed the way they conceptualized, approached, and/or managed pain, and reported thinking more holistically about pain management. Nearly all residents indicated they would like to have more training (98 %, N = 57) in integrative modalities.

CONCLUSIONS

Pediatric resident physicians are receptive to training in an interdisciplinary, integrative, pediatric pain management education intervention, and subsequently show positive changes in knowledge and comfort levels. There is a need and desire for additional pain education in resident training programs.

"A journey to learn about pain": the development and validation of a comic book about pain neuroscience education for children

BACKGROUND

Pain education resources for children using appropriate language and illustrations remain scarce.

OBJECTIVES

We aimed to summarize the development process and testing for face and content validity of a structured comic book about pain education for children.

METHODS

A first draft of a comic book was developed (Portuguese and English) based on pain education concepts. Experts in pediatric pain from different countries analyzed content, objectives, language, illustrations, layout, motivation, and cultural adjustment. A third draft developed in Portuguese considering experts' suggestions was presented to children and parents in Brazil. The total adequacy score was calculated from the sum of the scores obtained in each domain, divided by the maximum total score. Descriptive analysis is presented.

RESULTS

The expert panel was composed of 11 (64.7%) physical therapists, and 6 (35.3%) psychologists. The total adequacy score (0-100%) was 87.74%. The third draft version of the comic book was presented to 28 children and the final version was presented to 16 children with a mean age of 9.6 years. Children were totally satisfied (n=4; 26.7%) or satisfied (n=9; 56.2%) with the story of the comic book. The readability of the comic book was considered suitable for grades 4 to 6 educational level.

CONCLUSION

The comic book "A Journey to Learn about Pain" was validated for face and content validity by the expert panel and the Brazilian target population. This comic book is available in Portuguese and English and can be a potentially useful resource for children.

Development of the Conceptualization of Pain Questionnaire: A Measure to Study How Children Conceptualize Pain

(1) Background: Research has shown that thoughts about pain are important for the management of chronic pain in children. In order to monitor changes in thoughts about pain over time and evaluate the efficacy of treatments, we need valid and reliable measures. The aims of this study were to develop a questionnaire to assess a child’s concept of pain and to evaluate its psychometric properties; (2) Methods: This is a cross-sectional, two-phase, mixed-method study. A total of 324 individuals aged 8 to 17 years old responded to the newly created questionnaire. The Conceptualization of Pain Questionnaire (COPAQ) was calibrated using the Rasch model. The chi-square test was used for the fit statistics. Underfit and overfit of the model were determined and a descriptive analysis of infit and outfit was conducted to identify who responded erratically. Internal consistency was measured using the Person Separation Index (PSI); (3) Results: Fit to the Rasch model was good. Suitable targeting indicated which items were simple to answer; Person Fit identified 9.56% children who responded erratically; PSI = 0.814; (4) Conclusions: The findings suggest that COPAQ is a measure of a child’s concept of pain that is easy to administer and respond to. It has a good fit and a good internal consistency.

Exploring the Prevalence of Pediatric Chronic Pain and School Absenteeism for Therapists Working in Schools: A Systematic Review with Meta-Analysis

AIM

To explore the prevalence of school absenteeism for children with chronic pain and to identify the characteristics of children with chronic pain who report absenteeism.

METHODS

Systematic review with meta-analyses of quantitative studies. Studies were included if they reported mean days absent from school in children with chronic pain aged 5-18 years, attending a full-time school program. Quality of evidence was assessed using the Mixed Methods Appraisal Tool. Participant characteristics of age, gender, pain duration, pain type, and data collection setting were collated.

RESULTS

Eighteen quantitative studies involving 2963 children with chronic were included. Studies had moderate to high quality of evidence. Meta-analysis demonstrated 13.28 mean days were spent absent from school in a 60-day period (95% CI 10.21, 16.34) (p < 0.001). Participants were predominantly females (71.8%) aged 14.1 years (SD 2.32). The most experienced pain type was combined headache or head pain (46.9%) and average duration since pain onset was 32.5 months (SD 36.34).

CONCLUSIONS

Children with chronic pain aged 5-18 years are absent for approximately 22% of school days, in a 60-day period. Early, targeted intervention for absenteeism and poor school functioning is recommended. Future research could evaluate the role of school-based therapists in screening at risk students and improving attendance and outcomes.

Creating online animated videos to reach and engage youth: Lessons learned from pain science education and a call to action

Engaging youth in evidence-based health education has the capacity to positively impact their experiences of health and illness across the lifespan. In particular, pain science education is now an established part of the treatment arsenal for persistent pain conditions in adults, and there are calls to build educational resources for youth with pain. In this paper, we argue that high-quality online animated videos are a potentially excellent medium to engage youth at a mass level in pain science education. We present and compare two collaborations between clinician-scientists and industry to create and disseminate online animated videos for pain science education ("Mysterious Science of Pain" and "Tame the Beast"). We discuss the advantages, disadvantages, and methods of evaluation for each approach, as well as summarizing overall lessons learned. We provide this information as a guiding framework for clinician-scientists to collaborate with industry in building engaging and impactful health education resources for young people.

Squeezing a squishy object effectively controls pain in children during intravenous catheter insertion

This study aimed to identify the effect of distraction technique involving squeezing a squishy object on pain in children during intravenous catheter insertion. In this work, the control group posttest-only quasiexperimental design was used. This study involved 50 participants aged 3-15 years and was assigned into either intervention or control group. The intervention group was provided with a squishy object to squeeze as a form of distraction during intravenous catheter insertion, whereas the control group received the standard intervention. The pain was measured by using the Wong- Baker Faces Scale for 3-8 years old and the Visual Analog Scale or Numeric Rating Scale for children older than 8 years. Mann-Whitney analysis reveals significant difference in pain level between the intervention and control groups (P<0,001; α=0.05). The distraction technique involving squeezing a squishy object effectively reduced pain in children during intravenous catheter insertion and is recommended for pain management in nursing care in the pediatric ward.

Content and construct validity of the Diagnostic Criteria for Temporomandibular Disorders Axis I for children

OBJECTIVE

To perform the content and construct validation of the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) Axis I, for children 7-11 years old.

MATERIALS AND METHODS

A Delphi process was used to perform the content validity of the DC/TMD Axis I. One hundred eighty-nine 7- to 11-year-old children were assessed with the adapted instrument. Confirmatory factor analysis (CFA) was used to investigate construct validity of the DC/TMD for children. A baseline one-factor model was compared against a two-factor (Model 2) and a seven-factor (Model 3) models based on the original DC/TMD. Root mean squared error of approximation (RMSEA), comparative fit index (CFI), chi-square, change in chi-square and Cronbach's α were used to analyse the data. All analyses were performed in STATA^© version 13.0.

RESULTS

Items of the DC/TMD were reduced, "history time" was changed to 2 weeks, pain intensity was assessed through a face scale, and language was adapted to be better understood by children. The amount of muscle pressure was maintained as in the original DC/TMD Axis I. The CFA led to a two- and a seven-factor model, with good fit. The internal consistency of Model 2 was .91 and of Model 3, .94.

CONCLUSION

The results of this study provide evidence to support a seven-factor representation of the DC/TMD Axis I for 7- to 11-year-old children, as well as a two-factor structure. Such findings will begin to provide researchers with confidence in the properties of this instrument when considering its inclusion in clinical research.

Exploring the concept of pain of Australian children with and without pain: qualitative study

OBJECTIVE

A person's concept of pain can be defined as how they understand what pain actually is, what function it serves and what biological processes are thought to underpin it. This study aimed to explore the concept of pain in children with and without persistent pain.

DESIGN

In-depth, face-to-face interviews with drawing tasks were conducted with 16 children (aged 8-12 years) in New South Wales, Australia. Thematic analysis was used to analyse and synthesise the data.

SETTING

Children with persistent pain were identified from a pain clinic waiting list in Australia, and children without pain were identified through advertising flyers and email bulletins at a university and hospital.

PARTICIPANTS

Eight children had persistent pain and eight children were pain free.

RESULTS

Four themes emerged from the data: 'my pain-related knowledge', 'pain in the world around me', 'pain in me' and 'communicating my concept of pain'. A conceptual framework of the potential interactions between the themes resulting from the analysis is proposed. The concept of pain of Australian children aged 8-12 years varied depending on their knowledge, experiences and literacy levels. For example, when undertaking a drawing task, children with persistent pain tended to draw emotional elements to describe pain, whereas children who were pain free did not.

CONCLUSIONS

Gaining an in-depth understanding of a child's previous pain-related experiences and knowledge is important to facilitate clear and meaningful pain science education. The use of age-appropriate language, in combination with appropriate assessment and education tasks such as drawing and discussing vignettes, allowed children to communicate their individual concept of pain.

Best-Evidence for the Rehabilitation of Chronic Pain Part 1: Pediatric Pain

Chronic pain is a prevalent and persistent problem in middle childhood and adolescence. The biopsychosocial model of pain, which accounts for the complex interplay of the biological, psychological, social, and environmental factors that contribute to and maintain pain symptoms and related disability has guided our understanding and treatment of pediatric pain. Consequently, many interventions for chronic pain are within the realm of rehabilitation, based on the premise that behavior has a broad and central role in pain management. These treatments are typically delivered by one or more providers in medicine, nursing, psychology, physical therapy, and/or occupational therapy. Current data suggest that multidisciplinary treatment is important, with intensive interdisciplinary pain rehabilitation (IIPT) being effective at reducing disability for patients with high levels of functional disability. The following review describes the current state of the art of rehabilitation approaches to treat persistent pain in children and adolescents. Several emerging areas of interventions are also highlighted to guide future research and clinical practice.
