Implementation of an online pain science education for chronic musculoskeletal pain in Brazilian public health system: protocol for a hybrid type III randomised controlled trial with economic evaluation.

BACKGROUND: Although clinical practice guidelines recommend pain education as the first-line option for the management of chronic musculoskeletal pain, there is a lack of pain education programmes in healthcare. Thus, digital health programmes can be an effective tool for implementing pain education strategies for public health. This trial will aim to analyse the implementation and effectiveness outcomes of three online pain science education strategies in the Brazilian public health system (SUS) for individuals with chronic musculoskeletal pain. METHODS: We will conduct a hybrid type III effectiveness-implementation randomised controlled trial with economic evaluation. We will include adult individuals with chronic musculoskeletal pain, recruited from primary healthcare in the city of Guarapuava, Brazil. Individuals will be randomised to three implementation groups receiving a pain science education intervention (EducaDor) but delivered in different modalities: group 1) synchronous online; group 2) asynchronous videos; and group 3) interactive e-book only. Implementation outcomes will include acceptability, appropriateness, feasibility, adoption, fidelity, penetration, sustainability, and costs. We will also assess effectiveness outcomes, such as pain, function, quality of life, sleep, self-efficacy, and adverse effects. Cost-effectiveness and cost-utility analyses will be conducted from the SUS and societal perspectives. The evaluations will be done at baseline, post-intervention (10 weeks), and 6 months. DISCUSSION: This study will develop and implement a collaborative intervention model involving primary healthcare professionals, secondary-level healthcare providers, and patients to enhance self-management of chronic pain. In addition to promoting better pain management, this study will also contribute to the field of implementation science in public health by generating important insights and recommendations for future interventions.

Pain science education for children living with and beyond cancer: Challenges and research agenda.

Pain in children living with and beyond cancer is understudied and undertreated. Pain science education (PSE) is a conceptual change strategy facilitating patients' understanding of the biopsychosocial aspects of pain. Preliminary studies on the adaptation of PSE interventions to adults with and beyond cancer provide a foundation for pediatric research. PSE could help childhood cancer survivors experiencing persistent pain and pain-related worry after active treatment. PSE may also help children receiving cancer treatment, providing them with a foundation of adaptive pain beliefs and cognitions, and preparing them for procedural and treatment-related pain. We direct this paper toward pediatric oncology clinicians, policy makers, and researchers working with children living with and beyond cancer. We aim to (a) identify challenges in adapting PSE for children living with and beyond cancer, (b) offer possible solutions, and (c) propose research questions to guide the implementation of PSE for children living with and beyond cancer.

Assessing a child or adolescent with low back pain is different to assessing an adult with low back pain.

In contrast to an assessment of an adult presenting with low back pain (LBP), clinicians should utilise different approaches when assessing children and adolescents presenting with LBP. Children are not 'little adults'. There are some unique pathologies that only occur in this age group: (i) serious pathologies include infection, fracture, child abuse and malignancy; (ii) growth-related pathologies include scoliosis, Scheuermann's disease, pars fracture and spondylolysis; and (iii) rheumatological conditions include juvenile idiopathic arthritis and ankylosing spondylitis. With changes in each child occurring physically, emotionally and socially, a clinician's knowledge of typical developmental milestones is essential to identify regression or delayed development. When listening to a child discuss their pain experience, a flexible structure should be implemented that gives the capacity to actively listen to a child's narrative (and that of their guardian) and to conduct an effective physical examination. This viewpoint also summarises the relationship between potential clinical diagnoses and key elements of a physical examination. Deciding on the type and timing of paediatric-specific physical examination tests requires unique child-centred considerations. Paediatric-specific outcome measures should be used but implemented pragmatically, with consideration regarding the time, complexity and pathology suspected. Systematic and rigorous approaches to both treatment planning and re-assessment are then proposed for the assessment of children and adolescents presenting with LBP.

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 Importance of Perceived Relevance: A Qualitative Evaluation of Patient's Perceptions of Value and Impact Following a Low-Intensity Group-Based Pain Management Program.

Background and objectives: Limited evidence exists exploring perceptions of which aspects of a pain management program are perceived as valuable and impactful. The aim of this study was to explore patient beliefs about which aspects of a pain management program were valued and/or had perceived impact. Materials and Methods: One-on-one structured interviews were conducted with 11 adults three months after their completion of the Spark Pain Program at Westmead Hospital, Sydney, Australia. Concepts in the transcripts were inductively identified and explored, utilizing thematic analysis to better understand their relevance to the study aim. Results: Four themes emerged: (1) "The program overall was positive, but…"; (2) "I valued my improved knowledge and understanding of pain, but…"; (3) "I valued the stretching/relaxation/pacing/activity monitoring"; and (4) "I valued being part of a supportive and understanding group". Participants reported that they liked being treated as an individual within the group. A lack of perceived personal relevance of key messages was identified in some participants; it appears that patients in pain programs must determine that changes in knowledge, beliefs, and attitudes are personally relevant in order for the changes to have a significant impact on them. Conclusions: This study provides new insights into aspects of a pain management program that were perceived as valuable and impactful, areas that "missed the mark", and hypotheses to guide the implementation of service delivery and program redesign.

Which Patients With Chronic Pain Are More Likely to Improve Pain Biology Knowledge Following Education?

BACKGROUND: Pain education is an important part of multidisciplinary management of chronic pain. The characteristics of people likely to have more improvement in pain biology knowledge following pain education are unknown. OBJECTIVE: To identify the baseline factors predicting changes in pain biology knowledge in adults with chronic pain following a 2-hour multidisciplinary pain education session. METHODS: Fifty-five adults with chronic pain attended a 2-hour pain education session prior to a multidisciplinary assessment at a pain clinic. Patients completed the 12-item revised Neurophysiology of Pain Questionnaire (rNPQ, score/12) before and after the pain education session. The primary outcome was change in pain biology knowledge, evaluated with the change in rNPQ score. Ten preselected predictors were investigated using univariate models followed by multivariable models with a manual forwards-building process. RESULTS: Education level and age were significantly associated with change in rNPQ score in the univariate models. Participants with higher levels of education had, on average, 1.96 (0.68 to 3.23) points more improvement in rNPQ score than those with lower levels of education. For every 10 years older a participant was, his or her rNPQ score changed on average by 0.5 (0.1 to 0.8) points less. In the multivariable model, only the education level remained significant, explaining 17% of the variance (R2  = 0.17). The clinical variables that were assessed (pain severity, pain interference, pain self-efficacy, depression, anxiety, and pain catastrophizing) did not predict any knowledge change. CONCLUSION: This study suggests that, of those patients with chronic pain who choose to attend pain education, more educated patients are more likely to improve their pain biology knowledge after a pain education session.

The prevalence of chronic pain in adolescents in Central Switzerland: A cross- sectional school-based study protocol.

BACKGROUND: Chronic pain is associated with substantial personal suffering and societal costs and is a growing healthcare concern worldwide. While chronic pain has been extensively studied in adults, limited data exists on its prevalence and impact in adolescents. Understanding the prevalence and impact of chronic pain and pain beliefs in adolescents is crucial for developing effective prevention and treatment strategies. This study aims to estimate the prevalence, characteristics, and impact of chronic pain, and explore adolescents' knowledge and beliefs about pain. METHODS: This is an observational cohort study of school-going adolescents aged 11 to 17 years in Central Switzerland. The study will estimate the point prevalence, characteristics (location, intensity, frequency, duration) and impact (PROMIS Pediatric Short Form v2.0 -Pain Interference Scale, PPIS) of chronic pain in school-going adolescents. We will also measure and investigate pupils' beliefs about pain (Concept of Pain Inventory (COPI)). Data will be collected through manual and digital self-report questionnaires and from participants in primary, secondary, and high schools between September 2023 and January 2024. ANALYSES: The primary analyses will utilise descriptive statistics to estimate the point prevalence, characteristics, and impact of chronic pain. Secondary analyses will analyse associations and correlations between chronic pain, impact of pain and beliefs about pain. OUTCOMES: This study will provide an estimate of the prevalence, characteristics and impact of chronic pain in adolescents in Central Switzerland and a measure of adolescents' understanding and beliefs about pain. In doing so, this study will provide insights into the scale of chronic pain as a public health concern. By understanding adolescents' pain beliefs and their influence on pain experience, this study can contribute to the development of educational approaches to enhance adolescents' knowledge and understanding of pain in order to optimise the prevention and treatment of chronic pain in adolescents. The findings may be useful to healthcare professionals and funders, policymakers, and researchers involved in the prevention, assessment, and treatment of pain in adolescents.

Translation, contextual adaptation, and reliability of the Danish Concept of Pain Inventory (COPI-Adult (DK)) - A self-reported outcome measure.

OBJECTIVES: Pain is a growing concern globally, and an individual and societal burden. Pain science education (PSE) is a promising avenue for managing chronic pain, but targeted PSE is needed. The Concept of Pain Inventory for Adults (COPI-Adult) is a newly developed self-reported outcome measure aimed at targeting PSE. It is currently unavailable in Danish and has unknown reliability. The aims of this study were (1) to translate and contextually adapt to Danish and (2) to determine reliability in terms of test-retest reliability, internal consistency, and measurement error. METHODS: Step (1) was as follows: a dual panel approach was used to translate, contextually adapt into a Danish version. Step (2) was follows: a heterogenic sample of Danish adults >18 years (n = 150) was included in the test-retest analysis, test interval between 7 and 14 days, both answered via REDCap-link. Based on COSMIN recommendations, the following reliabilities were estimated: the test-retest using intraclass correlation coefficient (ICC2.1) and internal consistency using Cronbach's alpha level. Measurement error in terms of standard error of measurement (SEM) and smallest detectable change (SDC) were calculated. RESULTS: Step (1) was as follows: the first panel reached 100% consensus on the wording of the COPI-Adult (DK), with no alterations by the second panel. Step (2) was as follows: good to excellent test-retest reliability was found with ICC2.1 value (95% confidence interval) 0.88 (0.84-0.91), excellent internal consistency for the 13-item COPI-Adult (DK) with α = 0.939, SEM of 2.53, and SDC of 7.02. DISCUSSION: The COPI-Adult (DK) was successfully translated and contextually adapted. It is a reliable questionnaire with excellent internal consistency. The COPI-Adult (DK) shows promise in research and clinical practice.

The Effectiveness of Pain Science Education on Caregiver and Children's Knowledge, Beliefs, Attitudes, and Behaviors-A Systematic Review and Meta-Analysis.

Pain science education (PSE) can be used as part of treatment and prevention for chronic pain in children. We assessed the effectiveness of PSE on knowledge, beliefs, attitudes, and behaviors in children and the people that care for children. We set a minimum criterion for education to address pain biology knowledge. We included studies aimed at both treatment and prevention of chronic pain. We conducted searches using 5 databases. We assessed the risk of bias using the Cochrane Risk of Bias 2 tool. Data were pooled using a random-effects meta-analysis or assessed using a narrative synthesis. The certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation. We screened 14,505 records and included 7 studies involving 351 caregivers and 1,285 children. Four studies were included in meta-analyses. We found low-certainty evidence that PSE has a large beneficial effect on caregiver knowledge and beliefs compared with alternative education (standardized mean difference = 1.14 [95% confidence interval: .88-1.42]; I2 = 0%). We found no difference in functional disability in children with chronic pain after PSE (Functional Disability Inventory score mean difference = .73 [95% confidence interval: -.81 to 2.27; I = 0%]). Narrative syntheses showed low-certainty evidence for improved knowledge and beliefs in children with preventative and treatment effects. Overall, we found few studies, and along with high risk of bias, this significantly contributed to the low certainty of findings. The effect of learning pain science for both preventative and treatment effects in children, carers, and the child/carer dyad remains mostly unknown. This review was prospectively registered with The international Prospective register of systematic reviews (CRD42022344382) on July 22, 2022. PERSPECTIVE: This review examines the effect of PSE on pain-related knowledge, beliefs, attitudes, and behaviors in children and the people that care for children (0-18). The findings contribute to knowledge about pain treatments and health promotion for caregivers and their children with and without chronic pain.

Questionnaires assessing knowledge and beliefs about musculoskeletal conditions are potentially suitable for use, but further research is needed: a systematic review.

OBJECTIVES: To evaluate the measurement properties of Patient-reported outcome measures (PROMs) for knowledge and/or beliefs about musculoskeletal conditions. STUDY DESIGN AND SETTING: A systematic review was performed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines. This review was prospectively registered on PROSPERO - ID: CRD42022303111. Electronic databases, reference lists, forward citation tracking, and contact with experts were used to identify studies. Eligible studies were reports developing or assessing a measurement property of a PROM measuring musculoskeletal condition specific-knowledge and/or beliefs. We assessed the methodological quality and measurement properties of included studies. A modified Grading of Recommendations Assessment Development and Evaluation approach was used to rate the quality of evidence for each PROM. RESULTS: The literature search was performed from inception to 11th September 2023. Sixty records were included, reporting 290 individual studies, and provided information on 25 PROMs. Five PROMs presented sufficient structural validity, three presented sufficient cross-cultural validity, ten presented sufficient reliability, three presented sufficient criterion validity, six presented sufficient hypothesis-testing, and four presented sufficient responsiveness. No PROM presented sufficient evidence for content validity, internal consistency, and measurement error. Based on the available evidence, no PROM was classified as suitable for use according to the COSMIN recommendations. Twenty-four PROMs are potentially suitable for use, and one PROM is not recommended for use. CONCLUSION: No PROM designed to assess knowledge and/or beliefs about musculoskeletal conditions meets the COSMIN criteria of suitable for use. Most PROMs identified in this systematic review were considered as potentially suitable for use and need further high-quality research to assess their measurement properties.

We Are All in This Together-Whole of Community Pain Science Education Campaigns to Promote Better Management of Persistent Pain.

Persistent pain is a major public health issue-estimated to affect a quarter of the world's population. Public understanding of persistent pain is based on outdated biomedical models, laden with misconceptions that are contrary to best evidence. This understanding is a barrier to effective pain management. Thus, there have been calls for public health-based interventions to address these misconceptions. Previous pain-focussed public education campaigns have targeted pain beliefs and behaviours that are thought to promote recovery, such as staying active. However, prevailing pain-related misconceptions render many of these approaches counter-intuitive, at best. Pain Science Education improves understanding of 'how pain works' and has been demonstrated to improve pain and disability outcomes. Extending Pain Science Education beyond the clinic to the wider community seems warranted. Learning from previous back pain-focussed and other public health educational campaigns could optimise the potential benefit of such a Pain Science Education campaign. Pain Science Education-grounded campaigns have been delivered in Australia and the UK and show promise, but robust evaluations are needed before any firm conclusions on their population impact can be made. Several challenges exist going forward. Not least is the need to ensure all stakeholders are involved in the development and implementation of Pain Science Education public messaging campaigns. Furthermore, it is crucial that campaigns are undertaken through a health equity lens, incorporating underrepresented communities to ensure that any intervention does not widen existing health inequalities associated with persistent pain. PERSPECTIVE: Public misconceptions about pain are a significant public health challenge and a viable intervention target to reduce the personal, social, and economic burden of persistent pain. Adaptation of Pain Science Education, which improves misconceptions in a clinical setting, into the public health setting seems a promising approach to explore.

Do Teachers Question the Reality of Pain in Their Students? A Survey Using the Concept of Pain Inventory-Proxy (COPI-Proxy).

An assessment of a teacher's concept of their student's pain could be useful to guide preventative and targeted school-based pain science education. We aimed to assess a teacher's own concept of pain against their concept of their student's pain and examine the psychometric properties of the tool. Teachers of 10-12-year-old children were invited to participate in an online survey via social media. We modified the Concept of Pain Inventory (COPI) by inserting a vignette (COPI-Proxy), and we included questions to explore teacher stigma. Overall, a sample of 233 teachers participated in the survey. The COPI-Proxy scores showed that teachers can conceptualize their student's pain separately but are influenced by their own beliefs. Only 76% affirmed the pain in the vignette as real. Teachers used potentially stigmatizing language to describe pain in their survey responses. The COPI-Proxy had acceptable internal consistency (Cronbach's alpha = 0.72) and moderate convergent validity with the COPI (r = 0.56). The results show the potential benefit of the COPI-Proxy for assessing someone's concept of another's pain, particularly for teachers who are important social influencers of children.

Targeting Pain Science Education in Youth With Chronic Pain: What Are the Sticking Points for Youth and Their Parents?

OBJECTIVES: An important part of providing pain science education is to first assess baseline knowledge and beliefs about pain, thereby identifying misconceptions and establishing individually-tailored learning objectives. The Concept of Pain Inventory (COPI) was developed to support this need. This study aimed to characterize the concept of pain in care-seeking youth and their parents, to examine its clinical and demographic correlates, and to identify conceptual gaps. MATERIALS AND METHODS: Following an initial interdisciplinary evaluation, a cohort of 127 youth aged 8 to 18 years, and their parents, completed a series of questionnaires. RESULTS: Parents had slightly higher COPI scores than youth did, reflecting parents' greater alignment with contemporary pain science. The moderate positive association with older age among youth ( r =.32) suggests that COPI is sensitive to cognitive development and life experiences. Youth and parent COPI responses were weakly associated ( r =0.24), highlighting the importance of targeting the concept of pain in both groups. For both parents and youth, 'Learning about pain can help you feel less pain' was the least endorsed concept. This conceptual 'gap' is a key point of intervention that could potentially lead to greater engagement with multidisciplinary pain treatment. DISCUSSION: The COPI appears useful for identifying conceptual gaps or 'sticking points'; this may be an important step to pre-emptively address misconceptions about pain through pain science education. Future research should determine the utility of COPI in assessing and treating youth seeking care for pain. The COPI may be a useful tool for tailoring pain science education to youth and their parents.

Online information on chronic pain in 3 countries: an assessment of readability, credibility, and accuracy.

Objectives: To assess the readability, credibility, and accuracy of online information on chronic pain in Australia, Mexico, and Nepal. Methods: We assessed Google-based websites and government health websites about chronic pain for readability (using the Flesch Kincaid Readability Ease tool), credibility (using the Journal of American Medical Association [JAMA] benchmark criteria and Health on the Net Code [HONcode]), and accuracy (using 3 core concepts of pain science education: (1) pain does not mean my body is damaged; (2) thoughts, emotions, and experiences affect pain; and (3) I can retrain my overactive pain system). Results: We assessed 71 Google-based websites and 15 government websites. There were no significant between-country differences in chronic pain information retrieved through Google for readability, credibility, or accuracy. Based on readability scores, the websites were "fairly difficult to read," suitable for ages 15 to 17 years or grades 10 to 12 years. For credibility, less than 30% of all websites met the full JAMA criteria, and more than 60% were not HONcode certified. For accuracy, all 3 core concepts were present in less than 30% of websites. Moreover, we found that the Australian government websites have low readability but are credible, and the majority provided all 3 core concepts in pain science education. A single Mexican government website had low readability without any core concepts but was credible. Conclusion: The readability, credibility, and accuracy of online information on chronic pain should be improved internationally to support facilitating better management of chronic pain.

Assessing the Reconceptualization of Pain in Graduate-Entry Physiotherapy Students Using the Concept of Pain Inventory for Adults: The University of Technology Sydney Physiotherapy Student Surveys Project.

INTRODUCTION: Validly and reliably assessing conceptual change is essential for evaluating the effectiveness of pain science education for physiotherapy students. We aimed to 1) evaluate concept of pain before and after a 14-week pain science education university subject, 2) assess structural validity of the Concept of Pain Inventory for Adults (COPI-Adult) in postgraduate entry-level physiotherapy students, and 3) explore possible relationships between baseline variables and baseline COPI-Adult scores. REVIEW OF LITERATURE: As the COPI-Adult is a newly developed questionnaire, there is a lack of data regarding its psychometric properties. SUBJECTS: Of 129 enrolled students at an Australian university, 124 (96%) and 114 (88%) completed the baseline and follow-up questionnaires, respectively. METHODS: In this prospective cohort study, students who commenced the degree in 2020 or 2021 completed online questionnaires, including the COPI-Adult, at the start and end of their first semester. This semester included a 14-week pain science education subject and other physiotherapy-related subjects. Higher COPI-Adult scores (range = 0-52) indicate better alignment with contemporary pain science. We 1) compared differences in concept of pain before and after the semester, 2) performed a confirmatory factor analysis on the COPI-Adult, and 3) performed exploratory regression analyses. RESULTS: Concept of Pain Inventory for Adults scores increased from baseline (median [interquartile range]: 39 [36-44]) to follow-up (48 [44-51]). The COPI-Adult retained its 1-factor structure, with acceptable internal consistency (Cronbach's alpha = 0.80). Exploratory analysis showed that previously completing a subject on pain was related to higher COPI-Adult baseline scores. Age, gender, and mental health diagnosis did not relate to baseline COPI-Adult scores. DISCUSSION AND CONCLUSION: Following a 14-week pain science education subject embedded within a physiotherapy degree, students improved their concept of pain. The COPI-Adult maintains a 1-factor structure in this population. Completing a previous subject on pain was associated with higher COPI-Adult scores.

Comparison between 2000 and 2018 on the reporting of statistical significance and clinical relevance in physiotherapy clinical trials in six major physiotherapy journals: a meta-research design.

DESIGN: Meta-research. OBJECTIVE: To compare the prevalence of reporting p values, effect estimates and clinical relevance in physiotherapy randomised controlled trials (RCTs) published in the years 2000 and 2018. METHODS: We performed a meta-research study of physiotherapy RCTs obtained from six major physiotherapy peer-reviewed journals that were published in the years 2000 and 2018. We searched the databases Embase, Medline and PubMed in May 2019, and extracted data on the study characteristics and whether articles reported on statistical significance, effect estimates and confidence intervals for baseline, between-group, and within-group differences, and clinical relevance. Data were presented using descriptive statistics and inferences were made based on proportions. A 20% difference between 2000 and 2018 was regarded as a meaningful difference. RESULTS: We found 140 RCTs: 39 were published in 2000 and 101 in 2018. Overall, there was a high prevalence (>90%) of reporting p values for the main (between-group) analysis, with no difference between years. Statistical significance testing was frequently used for evaluating baseline differences, increasing from 28% in 2000 to 61.4% in 2018. The prevalence of reporting effect estimates, CIs and the mention of clinical relevance increased from 2000 to 2018 by 26.6%, 34% and 32.8% respectively. Despite an increase in use in 2018, over 40% of RCTs failed to report effect estimates, CIs and clinical relevance of results. CONCLUSION: The prevalence of using p values remains high in physiotherapy research. Although the proportion of reporting effect estimates, CIs and clinical relevance is higher in 2018 compared to 2000, many publications still fail to report and interpret study findings in this way.

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.

Using Mediation Analysis to Understand How Treatments for Paediatric Pain Work: A Systematic Review and Recommendations for Future Research.

Clinicians have an increasing number of evidence-based interventions to treat pain in youth. Mediation analysis offers a way of investigating how interventions work, by examining the extent to which an intermediate variable, or mediator, explains the effect of an intervention. This systematic review examined studies that used mediation analysis to investigate mechanisms of interventions on pain-relevant outcomes for youth (3-18 years) with acute or chronic pain, and provides recommendations for future mediation research in this field. We searched five electronic databases for clinical trials or observational longitudinal studies that included a comparison group and conducted mediation analyses of interventions on youth and assessed pain outcomes. We found six studies (N = 635), which included a total of 53 mediation models examining how interventions affect pain-relevant outcomes for youth. Five studies were secondary analyses of randomized controlled trials of psychological interventions for chronic pain; one was a longitudinal observational study of morphine for acute pain. The pain conditions studied were irritable bowel syndrome, functional abdominal pain, juvenile fibromyalgia, mixed chronic pain, and post-operative pain. Fourteen putative mediators were tested, of which three partially mediated treatment effect; seven did not significantly mediate treatment effect and four had mixed results. Methodological and reporting limitations were common. There are substantial gaps in the field with respect to investigating, and therefore understanding, how paediatric interventions work.

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.

Something Else Going On? Diagnostic Uncertainty in Children with Chronic Pain and Their Parents.

Diagnostic uncertainty, the perceived lack of an accurate explanation of the patient's health problem, remains relatively unstudied in children. This study examined the prevalence, familial concordance, and correlates of diagnostic uncertainty in children and their parents presenting to a multidisciplinary pain clinic in the United States. One hundred and twenty-six parents and 91 of their children (Mage = 13.93 years, range = 8-18 years) completed a brief three-item measure of diagnostic uncertainty, as well as measures of pain-related distress and functioning. Forty-eight percent of children and 37% of parents believed something else was going on with the child's pain that doctors had not found out about yet. Across the three items, 66%-77% of children and their parents agreed in their endorsement of diagnostic uncertainty. Parents who believed that something else was going on with their child's pain had children with higher avoidance of pain-related activities (F = 5.601, p = 0.020) and lower pain willingness (F = 4.782, p = 0.032). Neither parent nor child diagnostic uncertainty was significantly related to the child's pain-related functioning. Diagnostic uncertainty, particularly in parents, is relevant in the experience of pediatric chronic pain and warrants further investigation as both a risk factor and therapeutic target.
