The Concept of Pain Inventory (COPI): Assessing a Child’s Concept of Pain

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.

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.

Expressed Beliefs about the Cause of Pain in a Pediatric Population: A Qualitative Study

(1) Background: The aims of this study are to explore what beliefs children and adolescents manifest about the cause of the pain they describe, to compare whether there are differences between beliefs by age and the persistence of pain, and to relate the explanations of the cause of pain with current scientific evidence. (2) Methods: a cross-sectional qualitative study was used. The primary endpoint of the study was obtaining explanations of the cause of pain recorded by means of an open-ended question. The participants were school-age children attending a charted school in the province of Barcelona. (3) Results: The children and adolescents proposed a diverse range of explanations for the cause of pain that they reported in their responses. The most frequent explanation for the cause of pain were pathologies and injuries (45.95%), ergonomic issues (22.60%) and psychological issues (15.95%). (4) Conclusions: There is a lot of variety in the explanations that young people give about the cause of their pain in schoolchildren aged between 10 and 16 years old. There exists a high prevalence of explanations non-associated with tissue damage (ENAD) concerning the causes of pain described. It is necessary that future health prevention programs dedicated to early ages consider which beliefs about the cause of pain are the most frequent in the pediatric population.

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.

How does pain work? A qualitative analysis of how young adults with chronic pain conceptualize the biology of pain

BACKGROUND

Pain science education (PSE) is commonly integrated into treatments for childhood-onset chronic pain. A core component of PSE is learning about, and often reconceptualizing, the biology of chronic pain. Yet, few interventions have been developed specifically for young adults and little is known about how young adults conceptualize the biology of pain. This study used a qualitative methodology to examine how young adults with childhood-onset chronic pain understand the biology of pain, and the language they use in this meaning-making process, which may inform future interventions tailored to this age group.

METHODS

We identified a cohort of young adults with childhood onset chronic pain, and a subset of 17 young adults with continuing chronic pain completed individual, semi-structured interviews. Telephone interviews were audio-recorded, transcribed verbatim and analysed using reflexive thematic analysis.

RESULTS

We generated four themes that capture participants' conceptualizations of the biology of pain: (1) Something is wrong with the body, (2) An injury has not healed, (3) Nerves fire when they should not, (4) An overactive stress system.

CONCLUSION

These conceptualizations, and the language used by young adults with childhood-onset chronic pain to describe them are discussed. Recommendations are provided for how PSE interventions can be tailored for young adults.

SIGNIFICANCE

This study provides new qualitative insights reflecting a variety of ways that young adults with childhood-onset chronic pain conceptualize pain. Some conceptualizations of pain align with modern pain science principles (altered function of nervous and endocrine systems) while others conflict (unhealed injury). Health professionals can use these findings to tailor their pain education interventions by leveraging concepts that 'stick' for youth, being aware of, and interrogating, common misconceptions, and offering language and metaphors familiar to youth.

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.

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.

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.

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.

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

BACKGROUND

Pain neuroscience education (PNE) has received increasing research attention demonstrating beneficial effects on pain-related outcomes in adults. Conversely, studies on the effectiveness of PNE in children are scarce.

METHODS

This study investigated the effect of a pain educational video intervention on child pain-related outcomes (i.e. experienced pain intensity, pain-related fear and catastrophic worry about pain, pain threshold and pain knowledge) in healthy children undergoing an experimental pain task. Furthermore, the moderating role of children's demographic (i.e. sex and age) and psychological (i.e. baseline pain knowledge and anticipated pain intensity, pain-related fear and catastrophic worry) characteristics was examined. Participants were 89 children (M_age  = 11.85, SD = 1.78), randomly assigned to either a condition whereby they were instructed to watch a brief pain educational video (i.e. experimental group) or to a control condition whereby they did not watch any video.

RESULTS

Study findings revealed that accurate pain knowledge and pain threshold were higher amongst children in the experimental group compared to the control group. In contrast with expectations, no main effects of the video intervention were observed for experienced pain intensity, pain-related fear and catastrophic worry. Moderation analyses indicated that the video intervention contributed, in comparison with the control condition, to higher levels of pain knowledge amongst younger children only and to higher pain thresholds amongst boys only.

CONCLUSIONS

Further investigation is needed to optimize pain educational video interventions and to determine whether more beneficial outcomes can be found in clinical (i.e. non-experimental) situations and in children with persistent or recurring pain problems.

SIGNIFICANCE

Examining the impact of pain educational interventions within a non-clinical setting is deemed particularly important given that adaptive pain coping strategies likely play an important role in preventing the development and maintenance of future maladaptive pain-related behaviour. Further, study findings provide preliminary evidence of baseline and demographic (i.e. age and sex) characteristics explaining differences in the effect of a pain educational video intervention in pain knowledge and pain-related experiences during experimental pain.

Do Parental Pain Knowledge, Catastrophizing, and Hypervigilance Improve Following Pain Neuroscience Education in Healthy Children?

Pediatric chronic pain is a challenging problem for children and their families, although it is still under-recognized and under-treated. The aim of this study was to investigate whether a pain neuroscience education program for children (PNE4Kids) delivered to healthy children aged 8 to 12 years old and attended by their parents would result in improved parental knowledge about pain neurophysiology, decreased parental pain catastrophizing about their own pain and their children's, decreased parental pain vigilance and awareness, and decreased fear of pain in children. Twenty-seven healthy child-parent dyads received a 45 min PNE4Kids session. Demographic data were collected, and the Neurophysiology of Pain Questionnaire (NPQ), Fear of Pain Questionnaire-Parent Proxy Report (FOPQ-P), Pain Catastrophizing Scale (PCS), Pain Catastrophizing Scale for Parents (PCS-P), and the Pain Vigilance and Awareness Questionnaire (PVAQ) were completed by the parents before and after the PNE4Kids session. Twenty-six dyads completed study participation. In response to the PNE4Kids session, significant short-term (1 week) improvements were shown in the NPQ (p < 0.001) and the FOPQ-P (p = 0.002). Parents' level of pain knowledge and children's fear of pain, reported by their parents, improved after a 45 min PNE4Kids session. Thus, PNE4Kids should likewise be further investigated in healthy child-parent dyads as it might be useful to target parental and children's pain cognitions at a young age.

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.

Adolescents' Explanatory Models for Headaches and Associations with Behavioral and Emotional Outcomes

More than one-third of adolescents experience recurrent headaches. Usually, these headaches are of primary origin and modulated by different biological and psychosocial factors. While parents are often consulted in scientific research and medical care about the nature of their child's headache, it is unclear to what extent parents and their children agree upon the factors that cause them. Adolescents' own attributions of headaches have rarely been investigated, and it is unclear how those attributions affect behavioral and emotional outcomes. In the present study, adolescents with chronic headaches (N = 248) and their parents (N = 120) rated the influence of various biological and psychosocial factors on the adolescents' headaches. Associations between these factors and several behavioral and emotional outcomes were examined. The most frequently reported factor by both samples was stress; however, concordance between parents and adolescents was generally low. The factor "other disease" was significantly associated with medication consumption and school absence. This study is one of the first to provide insights into adolescents' own attributions of headaches. Furthermore, the significant associations of the factor with behavioral outcomes reveal the importance of understanding personal explanatory models of headache. Future studies should examine associations between subjective headache causes and the individual's experience of the disorder to improve headache interventions.
