Juvenile rheumatoid arthritis: pain-related and psychosocial aspects and their relevance for assessment and treatment

[Rheumatic pain and chronic pain in children, adolescents and young adults]

BACKGROUND

Rheumatic diseases, such as juvenile idiopathic arthritis (JIA), are typically associated with acute pain mainly caused by inflammation. Chronic pain is described as pain lasting at least 3 months. In JIA patients chronic pain may occur despite successful treatment. Chronic pain and pain disorders frequently occur during the course of the disease despite successful control of inflammation.

OBJECTIVE

Possible interrelations between JIA and pain disorders are presented.

METHOD

Besides a review of the available literature, a retrospective cohort study was conducted, including 906 patients with a chronic pain disorder with somatic and psychological factors (CPD) and/or a complex regional pain syndrome type I (CRPS I). The frequency of pre-existing rheumatic illnesses was analyzed.

RESULTS

The JIA is a risk factor for the development of a CPD. Especially polyarticular, extended oligoarticular, enthesitis-associated JIA and psoriatic arthropathy were found to be significantly associated with an increased risk for developing CPD. In contrast, an increased risk for development of CRPS I was not observed.

CONCLUSION

Our study demonstrates JIA to be a risk factor for the development of chronic pain not only as a result from malpositioning or arthrosis but also as a chronic pain disorder (CPD). Further studies are necessary to clarify the relevance of disease activity and duration and also of psychological factors for the pathogenesis.

Psychosocial research on systemic lupus erythematosus: a literature review

This article is the first to review published research on psychosocial factors and behavioral interventions related to systemic lupus erythematosus (SLE). The first section presents descriptive studies, followed by studies that investigate psychosocial factors as predictor and outcome variables. These studies demonstrate that the consideration of psychosocial factors is critical to understanding the disease experience of persons with SLE. Next, studies of behavioral interventions are presented, leading to the conclusion that randomized controlled trials are essential yet rare. The final section highlights limitations of the extant literature and suggests directions for future research and recommendations for clinicians.

Validity of an observation method for assessing pain behavior in individuals with multiple sclerosis

CONTEXT

Pain is a common and complex experience for individuals who live with multiple sclerosis (MS) and it interferes with physical, psychological, and social function. A valid and reliable tool for quantifying observed pain behaviors in MS is critical to understand how pain behaviors contribute to pain-related disability in this clinical population.

OBJECTIVES

To evaluate the reliability and validity of a pain behavioral observation protocol in individuals who have MS.

METHODS

Community-dwelling volunteers with MS (N=30), back pain (N=5), or arthritis (N=8) were recruited based on clinician referrals, advertisements, fliers, web postings, and participation in previous research. Participants completed the measures of pain severity, pain interference, and self-reported pain behaviors and were videotaped doing typical activities (e.g., walking and sitting). Two coders independently recorded frequencies of pain behaviors by category (e.g., guarding and bracing) and interrater reliability statistics were calculated. Naïve observers reviewed videotapes of individuals with MS and rated their pain. The Spearman's correlations were calculated between pain behavior frequencies and self-reported pain and pain ratings by naïve observers.

RESULTS

Interrater reliability estimates indicated the reliability of pain codes in the MS sample. Kappa coefficients ranged from moderate (sighing=0.40) to substantial agreements (guarding=0.83). These values were comparable with those obtained in the combined back pain and arthritis sample. Concurrent validity was supported by correlations with self-reported pain (0.46-0.53) and with self-reports of pain behaviors (0.58). Construct validity was supported by a finding of 0.87 correlation between total pain behaviors observed by coders and mean pain ratings by naïve observers.

CONCLUSION

Results support the use of the pain behavior observation protocol for assessing pain behaviors of individuals with MS. Valid assessments of pain behaviors of individuals with MS could lead to creative interventions in the management of chronic pain in this population.

Care delivery for the child to grow up despite the pain: the family's experience

This study aimed to understand the meaning of the experience of families having a child experiencing pain due to Juvenile Rheumatoid Arthritis and to construct a theoretical model representing this experience. Grounded Theory and Symbolic Interactionism were used as methodological framework and theoretical framework, respectively. Data were collected by semistructured interviews with 12 families. Data analysis allowed for the construction of the theoretical model Caring for the child to grow despite the pain, which describes an experience based on motivational elements: wanting to see the child without pain and wanting to see the child live a normal life, reviewing how the family lives the transition in its development cycles, retaking and integrating them in the family dynamic with the appearance of the disease and pain in the child. This theoretical model provides a framework for teaching, research and care, permitting advances in terms of theoretical nursing knowledge.

Pain, disability, and symptoms among siblings of children with functional abdominal pain

OBJECTIVE

To examine reports of pain, disability, and somatic and psychological symptoms among siblings of children with functional abdominal pain (FAP) and siblings of "healthy" comparison children.

METHODS

This survey study explored two groups of participants (FAP and healthy) consisting of (1) children with FAP and their siblings and parents and (2) healthy comparison children and their siblings, and parents. Participants included 13 FAP families and 10 healthy comparison families. Siblings and children were between 8 and 14 years of age. Measures included the Behavioral Assessment System for Children, Abdominal Pain Index, Children's Somatization Inventory, Functional Disability Inventory, and Family Inventory of Life Events. Cross-sectional data were analyzed using correlations and analysis of variance techniques.

RESULTS

Siblings of children with FAP reported significantly greater mean levels of emotional/ behavioral symptoms than siblings of healthy comparison children. No significant between-group differences were identified in FAP and healthy comparison parents' reports of siblings' pain or emotional/behavioral symptoms. There were significantly more persons with pain problems living in the homes of FAP families. Among FAP families, a greater number of parent-reported family stressful life events was significantly associated with sibling functional disability and somatic symptoms.

CONCLUSION

This investigation suggests that siblings of children with FAP experience more emotional/behavioral symptoms than peers and that their symptoms are not readily identified by parents. These findings highlight the importance of considering the psychological functioning of "unaffected" siblings and family stressors when children present with recurrent pain complaints.

A pain workshop: an approach to eliciting the views of young people with chronic pain

Chronic pain is complex and there is still much to discover about the burden that it places on children and their families. The aim of this study was to explore the way in which the experience of chronic pain impacts on the lives of young people. Through the use of a pain workshop that involved a series of guided activities and a focus group, young people were able to share their experiences with each other and the facilitators/researchers. Data were analysed using a theoretical coding technique supported by Atlas.ti. Five key interlinked themes emerged from the data and each theme is expressed in the words of the young people themselves: 'no one's pain's the same', 'getting on with it', 'it's hard 'cos...', 'keeping with the dream', and 'it depends ... some are OK'. The young people did experience significant disruption in their lives as a result of their pain. Pain was experienced as if it was both a separate entity as well as an intrinsic part of them and, to a degree, blighted their future. Based on the experiences shared by the young people, professionals need to develop insight and strategies into the challenges young people with chronic pain face on a daily basis.

Minimal difference in pain associated with change in quality of life in children with rheumatic disease

OBJECTIVE

To establish the minimal change on a pain visual analog scale (VAS) associated with change in self-reported quality of life in pediatric rheumatology patients.

METHODS

Subjects were a cohort of 533 pediatric rheumatology patients in Toronto. Pain and perceived quality of life were measured at 2 consecutive visits to a clinic.

RESULTS

Among patients who rated quality of life at the second visit as "a little better" and "much better," the mean change in pain score on a 10-cm VAS was reduced by 0.82 and 1.45 cm, respectively. For those whose quality of life changed to "a little worse" and "much worse," the pain scores increased by 1.90 and 3.69 cm.

CONCLUSION

Our results suggest that future studies of the assessment and treatment of pain in this population should aim for a minimum reduction in pain score of 0.82 cm on a 10-cm VAS to achieve clinical improvement in quality of life.

Health-related quality of life in children with arthritis

Health status results from an individual's values placed on the interactions among a person's physical state, associated mental perceptions and emotions, resulting behaviors, and environment. Improving health-related quality of life is the goal of all disease treatment. This article reviews the components of health status, summarizes relevant studies in children with rheumatic and related diseases, and considers the role that future studies will play in improving care for children with rheumatic diseases.

Life stressors, social resources, and coping skills in youth: applications to adolescents with chronic disorders

After setting out a conceptual framework that focuses on how personal and social resources aid adolescents in managing acute and chronic stressors, I describe methods by which to assess adolescents' family environments and specific life stressors and social resources, and the approach and avoidance coping responses adolescents use to manage life stressors. I then review some research that employs these concepts and methods to focus on the families and life contexts, and coping skills, of youth with chronic medical disorders, including juvenile rheumatic disease (JRD). I close by drawing implications for assessment and intervention and describing some fruitful areas for future research, such as examining the reciprocal linkages between parental and youth behavior, how adolescents' personal characteristics shape their life context, and how life crises and transitions enhance adolescents' development and maturation.

Social context of pain in children with Juvenile Primary Fibromyalgia Syndrome: parental pain history and family environment

OBJECTIVE

The purpose of this study was to describe parental pain history and the family environment as it relates to the functional status of children with Juvenile Primary Fibromyalgia Syndrome (JPFS).

DESIGN AND OUTCOME MEASURES

Twenty-nine parents of children with JPFS completed a pain history questionnaire, Von Korff Chronic Pain Grading system, and the Family Environment Scale (FES). Twenty-one adolescents with JPFS completed the FES, the Visual Analogue Scale for Pain, the modified Fibromyalgia Impact Questionnaire for Children, the Arthritis Impact Measurement Scales, and the Symptom Checklist-90-Revised. Correlational analyses were performed.

RESULTS

Parents of children with JPFS reported multiple chronic pain conditions, including but not limited to fibromyalgia. Parental pain history and the family environment correlated with the health status of adolescents with JPFS. Children with JPFS perceived the family environment as significantly more cohesive than did their parents. Greater incongruence between parent and child responses on the FES positively correlated with greater impairment.

CONCLUSIONS

These results suggest that family environment and parental pain history ày be related to how children cope with JPFS. Behavioral interventions targeting the family may improve the long-term functional status of children with JPFS.
