Immigration background as a risk factor of chronic pain and high-impact chronic pain in children and adolescents living in Spain: differences as a function of age

ABSTRACT

The number of people immigrating from one country to another is increasing worldwide. Research has shown that immigration background is associated with chronic pain (CP) and pain disability in adults. However, research in this issue in children and adolescents has yielded inconsistent results. The aims of this study were to examine (1) the association between immigration background, CP, high-impact chronic pain (HICP) in a community sample of children and adolescents; and (2) the extent these associations differed as a function of sex and age. Participants of this cross-sectional study were 1115 school children and adolescents (mean age = 11.67; 56% girls). Participants were asked to provide sociodemographic information and respond to a survey including measures of pain (location, extension, frequency, intensity, and interference). Results showed that having an immigration background was associated with a greater prevalence of CP (OR = 1.91, p <.001) and HICP (OR = 2.55, p <. 01). Furthermore, the association between immigration background and CP was higher in children (OR = 6.92, p <.001) and younger adolescents (OR = 1.66, p <.05) than in older adolescents. Children and adolescents with an immigration background are at higher risk for having CP -especially younger children- and HICP. More resources should be allocated in the prevention of CP and HICP in children and adolescents with an immigration background.

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.

Psychological factors and pain medication use in adolescents with chronic pain

OBJECTIVE

The purpose of this study was to examine (1) the associations of anxiety, depressive symptoms, and pain catastrophizing with pain medication use in adolescents with chronic pain and (2) the extent to which these associations differed as a function of adolescents' sex.

METHODS

Cross-sectional data from 320 adolescents 12-18 years of age with chronic pain were drawn from an epidemiological study on pediatric chronic pain conducted in Reus (Catalonia, Spain). Participants were asked to provide sociodemographic information and respond to measures assessing pain (location, frequency, intensity, and interference), pain medication use, anxiety, depressive symptoms, and pain catastrophizing. Point biserial correlations were conducted to examine univariate associations between the psychological variables and pain medication use. Hierarchical logistic regression analysis was used to examine these associations while controlling for demographic characteristics, pain intensity, and pain interference.

RESULTS

Anxiety, depressive symptoms, and pain catastrophizing were significantly associated with pain medication use in univariate analyses. Regression analysis identified pain catastrophizing as a unique independent predictor of pain medication use after controlling for the effect of demographic variables (sex and age), pain intensity, and pain interference (odds ratio = 1.1, P < .05). No moderating effect of adolescents' sex on the associations between psychological factors and pain medication use was found.

CONCLUSIONS

Adolescents with chronic pain with higher levels of pain catastrophizing use pain medications more often. Research to examine the impact of interventions targeting pain catastrophizing on pain medication use among adolescents with chronic pain would be an important next step.

The complexities of the sleep-pain relationship in adolescents: A critical review

Chronic pain is a common and disabling condition in adolescents. Disturbed sleep is associated with many detrimental effects in adolescents with acute and chronic pain. While sleep and pain are known to share a reciprocal relationship, the sleep-pain relationship in adolescence warrants further contextualization within normally occurring maturation of several biopsychological processes. Since sleep and pain disorders begin to emerge in early adolescence and are often comorbid, there is a need for a comprehensive picture of their interrelation especially related to temporal relationships and mechanistic drivers. While existing reviews provide a solid foundation for the interaction between disturbed sleep and pain in youth, we will extend this review by highlighting current methodological challenges for both sleep and pain assessments, exploring the recent evidence for directionality in the sleep-pain relationship, reviewing potential mechanisms and factors underlying the relationship, and providing direction for future investigations. We will also highlight the potential role of digital technologies in advancing the understanding of the sleep and pain relationship. Ultimately, we anticipate this information will facilitate further research and inform the management of pain and poor sleep, which will ultimately improve the quality of life in adolescents and reduce the risk of pain persisting into adulthood.

The Treatment of Pediatric Pain in Spain: A Survey Study

Pain is a common experience among children and adolescents, and pain management in this population is a challenge to clinicians. The aims of this study were to increase our understanding of current practices in the management of both acute and chronic pediatric pain in Spain, explore potential barriers to ideal practices, and identify professional needs as perceived by healthcare professionals. A total of 277 healthcare professionals took part, all of whom had wide experience in managing children and adolescents with pain (M [SD] age = 44.85, [10.73]; 75% women). Participants had to respond to a web-based survey with 50 questions related to pain education, organizational characteristics of their pain programs (including the characteristics of the patients treated), and current practices in the assessment and treatment of children and adolescents with pain. Almost all the participants (93%) acknowledged important gaps in their training, and only 47% reported that they had received specific education on the management of pediatric pain during their undergraduate and postgraduate studies. A third (31%) were members of multidisciplinary teams, and almost all (99%) understood that protocols to guide the management of pain in young people were necessary. However, only a few of them used a protocol to assess and treat (56% and 48%, respectively) acute and chronic pain (24% and 23%, respectively). The data also showed that a lack of pain education, coordination of professionals, and guidelines was perceived as an important barrier in the care provided to children and adolescents with pain in Spain. The findings of this study can now be used by healthcare professionals in Spain interested in managing pediatric pain, as well as policymakers concerned to improve the education of professionals and the care given to young people with pain.

Chronic Pain and High Impact Chronic Pain in Children and Adolescents: A Cross-Sectional Study

The aims of this study were to: 1) estimate the prevalence of chronic pain (CP) and high impact chronic pain (HICP) in a community sample of children and adolescents; and 2) compare groups (those without CP, those with CP but no HICP, and those with HICP) with respect to demographic variables, pain variables, and physical, psychological, and school-related function. One thousand one hundred and fifteen children and adolescents participated (56% girls; age: ߂ = 11.67; SD = 2.47; range = 8-18 years). The prevalence of CP and HICP was 46% and 5%, respectively, and was higher in girls and increased with age. Participants with HICP reported greater pain intensity and higher pain frequency than those with CP but no HICP. In addition, participants with HICP reported lower mobility, greater fatigue, worst sleep quality, more anxiety and depression symptoms, worst cognitive function, missing more school days, and worse perceived school performance. HICP is a prevalent condition in children and adolescents and is associated with many negative consequences. Stakeholders must be aware of this and ensure that treatment programs are available to reduce the individual and societal impact of HICP in young individuals. PERSPECTIVE: This article provides information on CP and HICP prevalence and impact in children and adolescents. By better understanding the nature and score of these conditions, we will be able to develop more effective early interventions to help this population and thereby reduce their long-term negative impact.

Pediatric sleep and pain: etiologies, consequences, and clinical considerations

STUDY OBJECTIVES

To examine current evidence of the relationship between sleep and pain from the neonatal period through adolescence. This review serves as a critical review of the literature and of the needs for future research on pediatric sleep and pain.

METHODS

The PubMed online database was queried from January 1, 1960, to March 1, 2020, producing 149 articles applicable to pain and sleep in the pediatric population. Of those, 97 articles were cited in this review with the key articles including over 3800 participants.

RESULTS

The pediatric literature supports the relationship between poor sleep (both sleep efficiency and nighttime awakenings) and subsequent risk for pain, especially among children with chronic disease. The reverse effect of pain on sleep is not yet well delineated. The key moderating factors explored in the literature are pharmacologic and nonpharmacologic therapies, psychologic health, and the etiology of pain. There is evidence that both altered sleep and pain early in life impact neurodevelopment, as seen by changes in sleep structure in clinical studies and alterations in brain development in animal models.

CONCLUSIONS

The complicated relationship between sleep and pain is critically important during pediatric development when alterations to a normal sleep structure can have a lifelong impact. It is becoming clear that sleep deprivation and poor sleep quality exacerbate pain. Further research is needed into the complex alterations of sleep in chronic pain conditions as well as treatments to improve sleep in pediatric care.

Subjective Sleep Complaints were Associated with Painful Temporomandibular Disorders in Adolescents: the Epidor-Adolescere Study

BACKGROUND

Sleep disturbances in adolescents has received a lot of attention in the literature and it is recognized as a serious health concern. The association between pain and sleep disturbances in adolescents has been extensively studied. However, to the best of our knowledge, there is a lack of studies investigating the association between various subjective sleep variables and painful TMD in adolescents.

OBJECTIVES

to investigate the association between painful TMD and subjective sleep variables in adolescents' non-clinical sample. We conducted a cross-sectional study. TMD was classified according to the RDC/TMD criteria. The Revised Face Scale evaluated TMD pain intensity, and pressure pain thresholds (PPTs) were assessed in trigeminal and extra-trigeminal areas. The subjective sleep variables were assessed according to the Sleep Disturbance Scale for Children and Sleep Behavior Questionnaire.

RESULTS

The final sample consisted of 690 adolescents (12.7±0.76 years), with 16.2% of them presenting painful TMD. Adolescents who frequently reported waking up more than twice per night and feeling tired when awake were more likely to present painful TMD symptoms [OR= 1.7 (95% CI: 1.04-2.90); p=0.034 and OR= 1.6 (95% CI: 1.01-2.48); p=0.046, respectively]. The intensity of TMD pain was negatively associated with sleep quality (p=0.015). Also, PPT values in the trigeminal and extra-trigeminal areas were negatively associated with total sleep time (p= 0.048 and p=0.042, respectively).

CONCLUSIONS

the present results point out the importance of considering sleep complaints associated with painful TMD in adolescents.

Trajectories and biopsychosocial predictors of daily acute pain in adolescents receiving treatment for pain: a daily diary study

Research regarding daily acute pain and its correlates has primarily been conducted with adolescents who have had major surgery or musculoskeletal pain, restraining efforts towards adapting interventions for adolescents with other sources of acute pain. We explored the trajectories and correlates of pain intensity. Adolescents with an opioid prescription to treat acute pain (N = 157) completed demographic questions, and the PROMIS pediatric depression and anxiety subscales. A 10-day daily diary assessed pain intensity, pain interference, sleep quality, and opioid use. Three trajectories of pain intensity emerged: (1) slow decreases in pain, (2) rapid decreases in pain, and (3) stable or slight increases in pain. Teens with stable pain demonstrated the greatest anxiety levels. Higher sleep quality predicted lower next day pain intensity and pain interference, when controlling for opioid use. Future research should employ intensive longitudinal methodology to further guide intervention development and prevent the transition to chronic pain.

Association Between Sleep Quality and Pain Intensity in Mild Patients with COPD: A Community Study

Purpose

Poor sleep quality and pain were common and had been proved as an important influenced factor of quality of life for patients with COPD. The association of sleep quality with pain has been observed in other population but remains unclear in mild patients with COPD from a community setting.

Methods

A cross-sectional study was conducted to include eligible mild patients with COPD in Pudong New District of Shanghai. A structured questionnaire was used to collect general and clinical information for the patients. The Chinese version of Pittsburgh Sleep Quality Index (PSQI) and the short form of McGill Pain Questionnaire (SF-MPQ) was used to assess sleep quality and intensity of pain. Logistic regression was performed to test the association between sleeping quality and pain intensity.

Results

Two hundred and sixty-four patients with COPD, with an average age of 64 years (SD 5.78 years), were enrolled, and of 52% were women. Seventy-one (26.9%) participants reported at least one exacerbation during the past year. About 28.2% of the patients were classified as having poor sleep quality. Sleep quality was significantly associated with PRI score (adjusted odds ratio (ORad)=2.16, 95% CI: 1.16–4.00) and PPI rank (ORad=1.90, 95% CI: 1.08–3.34). People with daytime disturbance were more likely to have pain (ORad =2.03, 95% CI: 1.18–3.50).

Conclusion

Poor sleep quality was common in mild patients with COPD in community and was associated with higher pain intensity. Pain may involve an impairment of sleep quality.

The Silhouettes Fatigue Scale: a validity study with individuals with physical disabilities and chronic pain

PURPOSE

Fatigue is known to interfere with function in individuals with physical disabilities. In order to monitor changes in fatigue over time and evaluate the efficacy of treatments, psychometrically sound measures of fatigue are needed. The aim of this work was to evaluate the validity of the Silhouettes Fatigue Scale with English instructions (SFS-EN) in a sample of adults with physical disabilities living in the USA.

METHODS

Individuals with medical conditions associated with physical disabilities responded to an online survey that included the SFS-EN as well as another validated measure of fatigue (PROMIS short form-4a Fatigue Scale), and measures of pain intensity and pain catastrophizing.

RESULTS

523 individuals participated (mean age = 59.1 years; SD = 11.4). Most participants were Caucasian (89%), women (59%) and unemployed (71%). Results showed strong positive correlations between both measures of fatigue, supporting the convergent validity of the SFS-EN. In addition, the magnitude of this association was significantly greater than the association between the scores of the SFS-EN and the measures of pain intensity and pain catastrophizing, supporting the former's discriminant validity.

CONCLUSIONS

The findings extend previous results supporting the SFS as a brief, easy to administer and understand, and valid measure of fatigue.IMPLICATIONS FOR REHABILITATIONFatigue is common in adults with physical disabilities and chronic pain.The Silhouettes Fatigue Scale (SFS) is a new single-item measure of general fatigue.Findings show that the SFS with English instructions (SFS-EN) is an easy to understand measure.Results support the convergent and discriminant validity of the SFS-EN score in adults with physical disabilities and chronic pain.

Sport Specialization and Quality of Life among Middle- and High-School Long-Distance Runners of Different Injury Status: A Retrospective Study

Running-related injuries are prevalent in adolescent long-distance runners. The aim of our retrospective study was to compare differences in sport specialization, running habits,quality of life, and sleep habits among middle-and high-school long-distance runners of different injury statuses. Middle- and high-school long-distance runners across the United States were recruited via cross-country coaches and athletic directors between January and May 2020. Participants completed an online survey with questions related to demographics, sport specialization, running habits, quality of life, sleep, and self-reported injury history. Overall, 306 participants completed the survey (male = 107, female = 176, unspecified = 23; age = 15.7 ± 1.1 years). Of the participants, 178 (58.2%) reported no history of injury, 101 (33.0%) reported a previous injury, and 27 (8.8%) reported a current injury. Middle- and high-school runners with a current injury reported significantly lower overall health (p= .01) and average distance per run (p = .05) than uninjured runners. No significant differences were found among injury status and sport specialization level, quality of life, sleep habits, or running volume (p> .05). Runners with a self-reported previous or current injury do not appear to be classified as high-specialized runners more frequently than uninjured runners.

ASSOCIATION BETWEEN SLEEP QUALITY AND PAIN IN YOUNG AMATEUR ATHLETES

ABSTRACT Introduction: It has been shown that there is a close association between sleep quality and pain. In young athletes, sleep disorders and pain have a particularly high prevalence; however, the relationship between them has not been widely studied. Objective: To study the association between sleep quality and pain in young athletes. Methods: A cross-sectional study was conducted in which 71 young amateur athletes (39 males) were included. The mean age was 16.9 ± 1.2 years, with 6.5 ± 3.2 years of sports practice and 5.2 ± 1.2 hours of training per week. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). The participants were classified according to sleep quality, as PSQI-I = without sleep disorders, PSQI-II = requiring medical assistance and PSQI-III = requiring medical assistance and treatment. Also, pain intensity was assessed on the Numerical Rating Scale, both at rest (NRSr) and during sports activity (NRSs), along with pain duration. Results: The individuals classified as PSQI-III presented higher NRSr (Mdn = 2.0; IQR = 4.0 vs. Mdn = 0.0; IQR = 2.0; p = 0.04) and higher NRSs (Mdn = 4.0; IQR = 5.0 vs. Mdn = 0.0; IQR = 2.0; p = 0.03) than the individuals classified as PSQI-I. No differences were observed in relation to pain duration. The PSQI score was positively but weakly associated with NRSr (rs = 0.24, p=0.046) and NRSs (rs = 0.27, p = 0.03) but not with pain duration. Conclusion: Young athletes with lower levels of sleep quality show higher levels of pain at rest and during sports practice. Therefore, sleep quality and pain should be considered in the routine assessment of young athletes, by technical and health teams. Level of evidence III; type of study: Cross-sectional .

The management of pediatric chronic pain in Spain: a web-based survey study

OBJECTIVE

To improve understanding of current practices in the treatment of children and adolescents with chronic pain in Spain.

METHODS

A web-based survey was conducted with a representative sample of healthcare professionals (i.e. general practitioners [GP] and pediatricians [P]) in Spain. The survey included 23 questions on the pain education and training they had been given, and on organizational issues and current practices in the assessment and management of children and adolescents with chronic pain in their current work.

RESULTS

The survey was completed by 191 professionals (75 GP and 116 P) with wide experience (mean number of years = 21; SD = 8) in the management of children and adolescents with chronic pain. Half of the participants reported that they had not been given any specific education or training on pediatric chronic pain management during their studies, and 80% acknowledged important gaps in their training. Although the majority assessed pain when attending children with chronic pain (80%), and almost all (96%) believed that protocols to guide the management of chronic pain in young people were necessary, only a third reported that they usually use a specific protocol. Less than 25% were part of a multidisciplinary team addressing the needs of children and adolescents with chronic pain.

CONCLUSIONS

This survey has identified considerable limitations in the management of children and adolescents with chronic pain in Spain. This information can now be used by policy makers to improve the care given to children and adolescents suffering from chronic pain and their families.

Beyond pain intensity and catastrophizing: The association between self-enhancing humour style and the adaptation of individuals with chronic pain

BACKGROUND

Many questions regarding the process by which self-enhancing humour style has an effect on chronic pain individuals' adjustment remain unanswered. The aim of the present study was to analyse the association of self-enhancing humour style with adjustment in a sample of individuals with chronic pain, over and above the role of catastrophizing and pain intensity. Adjustment was assessed using measures of depression, pain interference and flourishing. We also examined the indirect association between self-enhancing humour style and adjustment via pain acceptance.

METHODS

The study included 427 patients with heterogeneous chronic pain conditions. The study hypotheses were tested using three multiple linear regression analyses, one for each of the criterion variables.

RESULTS

Consistent with the study hypothesis, both direct and indirect associations were found between self-enhancing humour style and depressive symptoms, pain interference and flourishing via pain acceptance.

CONCLUSIONS

Self-enhancing humour style could potentially help individuals with chronic pain to gain perspective and distance themselves from the situation through the acceptance of pain-related negative emotions.

SIGNIFICANCE

Very few studies have investigated the relationship between humour styles and adjustment in chronic pain samples. The results of the current study support the idea that adaptive dispositional traits, such as patient's self- enhancing humour style, play a role in the adaptation of individuals with chronic pain. Given that the association between self-enhancing humour style and adjustment evidenced an indirect association through pain acceptance, training in the use of humour, as individuals with self-enhancing humour style do, might be a useful addition to ACT treatment.

Chronic Pain and Sleep Disturbances: A Pragmatic Review of Their Relationships, Comorbidities, and Treatments

Objective

The objective of this review is to answer three questions: 1) How are chronic pain severity and pain duration affected in patients with chronic pain and sleep disturbances that occur simultaneously? 2) What are common comorbidities and pain-related symptoms seen in patients with chronic pain and sleep disturbances? and 3) What are potentially effective pharmacological and nonpharmacological treatment options for both conditions?

Methods

Ovid Medline and PubMed were searched. Search terms included sleep wake disorder, chronic pain, fibromyalgia, treatment outcome, psychotherapy, complementary therapies, and therapeutics. Studies that assessed outcomes between individuals with chronic pain and those with concurrent chronic pain and sleep disturbances were included. Randomized controlled clinical trials of treatments for both conditions were included.

Results

Sixteen studies indicated that patients with both chronic pain and sleep disturbances have greater pain severity, longer duration of pain, greater disability, and are less physically active than those without sleep disturbances. Patients with both conditions are more likely to have concurrent depression, catastrophizing, anxiety, and suicidal ideation. Thirty-three randomized controlled trials assessed treatment for both chronic pain and sleep disturbances. Pregabalin was the most frequently studied medication, showing improvement in pain and sleep symptoms. Cognitive behavioral therapy for insomnia showed long-term improvement in sleep for patients with chronic pain.

Conclusions

Individuals with chronic pain and sleep disturbances have greater symptom severity, longer duration of symptoms, more disability, and additional comorbidities. Pharmacological and nonpharmacological treatments may be useful in the treatment of concurrent chronic pain and sleep disturbances, but further study is needed.

The role of physical, cognitive and social factors in pain interference with activities of daily living among individuals with chronic cancer pain

OBJECTIVES

The aim of this study was to better understand the role that physical, cognitive and social factors play in pain interference with activities of daily living among individuals with cancer and chronic pain.

METHOD

In this cross-sectional study, interviews with 156 patients with chronic cancer pain were conducted across five tertiary level hospitals in the province of Tarragona (Spain). Participants were interviewed individually and provided information about the presence and characteristics of pain, fatigue, catastrophic thinking, social support and the impact of pain on their daily activities.

RESULTS

Pain intensity (β = 0.23, p = .003), fatigue (β = 0.26, p < .001) and pain catastrophising (β = 0.39, p < .001) were significantly and positively associated with pain interference in daily activities. Pain interference scores were not explained by social support (β = 0.12 p = .090) or socio-demographic factors (R²  = .005; p = .94).

CONCLUSION

This study provides important new findings regarding the association between physical, cognitive and social factors and function of individuals with cancer and chronic pain, thus supporting a biopsychosocial approach to the management of chronic pain in individuals with cancer.

Worse health status, sleeping problems, and anxiety in 16-year-old students are associated with chronic musculoskeletal pain at three-year follow-up

Background

Chronic musculoskeletal pain is common in adolescents, and it has been shown that adolescents with pain may become young adults with pain. Pain often coincides with psychosomatic symptoms in adults, but little is known about longitudinal associations and predictors of pain in adolescents. The aim was to investigate chronic musculoskeletal pain and its associations with health status, sleeping problems, stress, anxiety, depression, and physical activity in 16-year-old students at baseline, and to identify risk factors using a three-year follow-up.

Methods

This was a longitudinal study of 256 students attending a Swedish upper secondary school. Questionnaires regarding chronic musculoskeletal pain and distribution of pain (mannequin), health status (EQ-5D-3 L), sleeping problems (Uppsala Sleep Inventory), stress symptoms (single-item question), anxiety and depression (Hospital Anxiety and Depression Scale), and physical activity (International Physical Activity Questionnaire) were issued at baseline and follow-up. Student’s t-test and chi² test were used for descriptive statistics and logistic regression analyses were used to study associations between chronic pain and independent variables.

Results

Fifty-two out of 221 students at baseline (23.5%) and 39 out of 154 students at follow-up (25.3%) were categorized as having chronic musculoskeletal pain. Chronic musculoskeletal pain at follow-up was separately associated with reporting of an EQ-5D value below median (OR 4.06, 95% CI 1.83–9.01), severe sleeping problems (OR 3.63, 95% CI 1.69–7.82), and possible anxiety (OR 4.19, 95% CI 1.74–10.11) or probable anxiety (OR 3.82, 95% CI 1.17–12.48) at baseline. Similar results were found for associations between chronic musculoskeletal pain and independent variables at baseline. In multiple logistic regression analysis, chronic musculoskeletal pain at baseline was a predictor of chronic musculoskeletal pain at follow-up (OR 2.99, 95% CI 1.09–8.24, R² = 0.240).

Conclusion

Chronic musculoskeletal pain at baseline was the most important predictor for reporting chronic musculoskeletal pain at the three-year follow-up, but a worse health status, severe sleeping problems, and anxiety also predicted persistence or development of chronic musculoskeletal pain over time. Interventions should be introduced early on by the school health services to promote student health.

Evaluating the psychometric properties of the Widespread Pain Index and the Symptom Severity scale in youth with painful conditions

Background

Assessing features of centralized pain may prove to be clinically meaningful in pediatric populations. However, we are currently limited by the lack of validated pediatric measures.

Aim

We examined the psychometric properties of the Widespread Pain Index (WPI) and Symptom Severity (SS) scale, to assess features of centralized pain, in youth with painful conditions from three clinical samples: (1) musculoskeletal surgery, (2) headache, and (3) chronic pain.

Methods

Participants were 240 youth aged 10-18 years (Mage=14.8, SD=1.9) who completed the WPI and SS scale. Subsets of participants also completed additional measures of pain region, pain intensity, quality of life, pain interference and physical function.

Results

Increased features of centralized pain by age were seen for the WPI (r=0.27, p<0.01) and SS scale (r=0.29, p<0.01). Expected differences in sex were seen for the WPI (sex:t₁₃₂=-3.62, p<0.01), but not the SS scale (sex:t₂₂₃=-1.73, p=0.09). Reliability for the SS scale was adequate (α=.70). Construct validity was demonstrated through relationships between the WPI and pain regions (r=.57, p<0.01), and between the SS scale and quality of life (r=-.59, p<0.01) and pain interference (r=.56, p<0.01). Criterion validity was demonstrated by differences on the WPI between the surgery sample and the headache and chronic pain samples (F_2,237=17.55, p<0.001). Comprehension of the SS scale items was problematic for some youth.

Conclusions

The WPI showed adequate psychometric properties in youth; however the SS scale may need to be modified. Our findings support the need to develop psychometrically sound instruments for comprehensive assessment of pain in pediatric samples.

Sleep disturbance in individuals with physical disabilities and chronic pain: The role of physical, emotional and cognitive factors

BACKGROUND

Sleep problems are common for individuals living with physical disabilities and chronic pain. However, the factors that influence the relationship between pain and sleep problems in these populations remain unknown.

OBJECTIVE

The aim of this study was to increase our understanding of the physical, emotional and cognitive factors associated with sleep disturbance in individuals with chronic health conditions often associated with physical disabilities.

METHODS

Participants were recruited from a database of individuals with a variety of chronic health conditions, including multiple sclerosis, spinal cord injury, back pain, osteoarthritis, and amputations. To participate in the study, they needed to report having a chronic pain problem. Participants completed an online survey using REDCap assessing average pain intensity (Numerical Rating Scale-11), pain extent (number of painful body areas), sleep disturbance (PROMIS Sleep Disturbance), depression (PROMIS Emotional Distress-Depression) and catastrophizing (Coping Strategies Questionnaire). A total of 455 participants (M_age = 58.9; SD = 11.4), of which 292 (64%) were women, provided complete data. We performed a series of four regression analyses.

RESULTS

After controlling for age and sex, the predictors explained an additional 7-16% of the variance in sleep disturbance. The final model with all of the predictors explained 22%.

CONCLUSIONS

Consistent with the study hypothesis, all the variables examined made significant and independent contributions to the variance in sleep disturbance. The findings provide additional evidence that physical, emotional and cognitive factors all play a role in the sleep quality of individuals with chronic health conditions often associated with physical disabilities.

Pain extent and function in youth with physical disabilities

Background

The aim of this study was to increase our understanding of the role that spatial qualities of pain (location and extent) play in functioning, among youths with disabilities and chronic pain.

Methods

One-hundred and fifteen youths (mean age 14.4 years; SD ±3.3 years) with physical disabilities and chronic pain were interviewed and were asked to provide information about pain locations and their average pain intensity in the past week, and to complete measures of pain interference, psychological function and disability. Most of the participants in this sample were males (56%), Caucasian (68%), and had a cerebral palsy (34%) or muscular dystrophy (25%) problem. Most participants did not report high levels of disability ( X¯=12.7, SD ±9.5, range 0–60) or global pain intensity ( X¯=3.2, SD ±2.4, range 0–10).

Results

Pain at more than one body site was experienced by 91% of participants. There were positive associations between pain extent with pain interference (r = 0.30) and disability (r = 0.30), and a negative association with psychological function (r = –0.38), over and above average pain intensity. Additionally, pain intensity in the back (as opposed to other locations) was associated with more pain interference (r = 0.29), whereas pain intensity in the shoulders was associated with less psychological function (r = –0.18), and pain intensity in the bottom or hips was associated with more disability (r = 0.29).

Conclusion

The findings support the need to take into account pain extent in the assessment and treatment of youths with physical disabilities and chronic pain, call our attention about the need to identify potential risk factors of pain extent, and develop and evaluate the benefits of treatments that could reduce pain extent and target pain at specific sites.

Psychological Neuromodulatory Treatments for Young People with Chronic Pain

The treatment of young people with chronic pain is a complex endeavor. Many of these youth do not obtain adequate relief from available interventions. Psychological neuromodulatory treatments have been shown to have potential benefit for adults with chronic pain. Here, we review and summarize the available information about the efficacy of three promising psychological neuromodulatory treatments-neurofeedback, meditation and hypnosis-when provided to young people with chronic pain. A total of 16 articles were identified and reviewed. The findings from these studies show that hypnotic treatments are effective in reducing pain intensity for a variety of pediatric chronic pain problems, although research suggests variability in outcomes as a function of the specific pain problem treated. There are too few studies evaluating the efficacy of neurofeedback or meditation training in young people with chronic pain to draw firm conclusions regarding their efficacy. However, preliminary data indicate that these treatments could potentially have positive effects on a variety of outcomes (e.g., pain intensity, frequency of pain episodes, physical and psychological function), at least in the short term. Clinical trials are needed to evaluate the effects of neurofeedback and meditation training, and research is needed to identify the moderators of treatment benefits as well as better understand the mechanisms underlying the efficacy of all three of these treatments. The findings from such research could enhance overall treatment efficacy by: (1) providing an empirical basis for better patient-treatment matching; and (2) identifying specific mechanisms that could be targeted with treatment.
