A bio-psychosocial evaluation of ten adolescents with fibromyalgia

Psychological aspects of juvenile fibromyalgia syndrome: a literature review

Juvenile fibromyalgia syndrome (JFMS) is a non-inflammatory chronic pain condition that occurs mainly in girls aged 9-15 years. JFMS is characterized by constant widespread pain in different parts of the body, poor sleep quality, daytime sleepiness and an altered mood. Concomitant psychological and organic factors result in a diminished capacity to cope with pain. The quality of life of individuals with chronic pain and their caregivers is severely restricted and the occurrence of symptoms of anxiety and depression is common in this population. The aim of the present study was to perform a systematic review of the literature on psychosocial factors related to JFMS. The findings reveal differences in opinion between patients and family members regarding the effect of the condition, as mothers tend to classify JFMS as more severe than the patients themselves. Individuals with JFMS seem to share the same personality traits and there seems to be a type of family environment that is favorable to the occurrence of this condition. Psychological and functional aspects should be treated with methods that can help patients and family members alter their coping strategies regarding day-to-day problems, attenuate the dysfunctional consequences of pain and fatigue and diminish the risk of catastrophizing that individuals submitted to constant pain develop in relation to their surrounding environment.

[Juvenile fibromyalgia syndrome]

OBJECTIVE

The aim was to develop a guideline for diagnostic procedures and treatment of juvenile fibromyalgia syndrome (JFMS) in cooperation with 10 German medical and psychological associations and 2 patient self-help groups.

METHODS

A systematic literature search, including all controlled studies evaluating diagnosis and treatment of JFMS, was performed in the Cochran Collaboration Reviews (1993-12/2006), Medline (1980-12/2006), PsychInfo (1966-12/2006) and Scopus (1980-12/2006). Levels of evidence were assigned according to the classification system of the Oxford Centre for Evidence-Based Medicine. Grading of the strengths of recommendations was performed according to the German program for disease management guidelines. Standardized procedures to reach a consensus on recommendations were used.

RESULTS

Pain in children/adolescents involving several body areas and lasting >3 months without an obvious somatic cause is called JFMS or pain amplification syndrome. Therapeutically, a multidisciplinary concept with psychotherapy and physiotherapy, relaxation techniques and patient education is recommended.

CONCLUSION

These guideline will contribute to a better recognition and standardized care of patients with JFMS and facilitate clinical studies.

Fibromyalgie: Eine körperliche Krankheit oder unspezifische psychische Störung?

Zusammenfassung. Die Fibromyalgie (FM) ist eine multilokale, nichtentzündliche Schmerzstörung an bestimmten druckschmerzhaften Punkten des Bewegungsapparates. Hinzu treten multiple funktionelle Symptome wie Schlafstörungen, Magen- und Darmbeschwerden, Konzentrationsstörungen und nicht zuletzt psychische Beeinträchtigungen und Störungen (Depression, Angst, eingeschränkte Lebensqualität). Bei Kindern und Jugendlichen stellt die FM eine eher seltene Extremform weitverbreiteter funktioneller Schmerzstörungen des Bewegungsapparates dar. Die medizinische Diagnostik ergibt keinen pathologischen Befund. Entsprechend kontrovers wird die Ätiopathogenese diskutiert. Drei Störungsmodelle werden vorgestellt: (1) FM als organische Erkrankung auf der Basis einer genetischen Prädisposition, mit Regulationsstörungen der Hormonachse, des Vegetativums und der Neurotransmittersysteme, (2) FM als chronisch-funktionelle Schmerzstörung infolge einer Schmerzsensitivierung und -verstärkung (Wind-up-Phänomen), (3) FM als psychische Störung mit hoher Komorbidität im Bereich der Depression und Angststörungen im Sinne einer somatoformen Schmerzstörung mit katastrophisierender Symptomverarbeitung und exzessiv gesteigertem Krankheits- und Inanspruchnahmeverhalten. Zur Integration dieser Störungsmodelle stellt der Beitrag ein entwicklungspsychopathologisches Modell vor. Es unterscheidet vier Störungsetappen, denen jeweils spezifische medizinische wie psychologische Interventionsmethoden zugeordnet werden können; ausführlich werden verhaltensmedizinische Strategien vorgestellt.

Assessment and management of pain syndromes and arthritis pain in children and adolescents

Chronic musculoskeletal pain, whether it is idiopathic or disease-related, is common in childhood. Pediatric rheumatologists and other pediatric health care providers must understand the epidemiology of musculoskeletal pain as part of childhood, diagnose pain syndromes in children and rule out rheumatic disease, and be willing to initiate treatment of pain in children and adolescents. Practitioners' ability to carry out these tasks is enhanced by an awareness of the biopsychosocial model of pain, which integrates biologic, environmental, and cognitive behavioral mechanisms in describing the causes and maintenance of children's pain. A growing body of research in rheumatic diseases, such as JIA, and idiopathic musculoskeletal pain syndromes, such as JPFS, highlights the importance of environmental and cognitive behavioral influences in the pain experience of children in addition to the contribution of disease activity. These influences include factors innate in the child, such as emotional distress, daily stress, coping, and mood, and familial factors, such as parental psychologic health, parental pain history, and the nature of family interactions. Addressing these issues, while providing aggressive traditional medical management, optimizes pain treatment and improves overall quality of life for children who have musculoskeletal pain.

Development and evaluation of a cognitive-behavioral intervention for juvenile fibromyalgia

OBJECTIVE

To describe the development and test the efficacy of a cognitive-behavioral intervention (CBT) for juvenile fibromyalgia.

METHOD

Sixty-seven children with fibromyalgia and their parents were recruited to participate in an 8-week intervention that included modules of pain management, psychoeducation, sleep hygiene, and activities of daily living. Children were taught techniques of cognitive restructuring, thought stopping, distraction, relaxation, and self-reward. Additionally, they kept daily pain and sleep diaries. Children completed questionnaires of pre- and post-treatment measuring physical status and psychological functioning.

RESULTS

Following CBT, children reported significant reductions (p < .006) in pain, somatic symptoms, anxiety, and fatigue, as well as improvements in sleep quality. Additionally, children reported improved functional ability and had fewer school absences.

CONCLUSION

Children with fibromyalgia can be taught CBT strategies that help them effectively manage this chronic and disabling musculoskeletal pain disorder.

Pediatric pain syndromes and management of pain in children and adolescents with rheumatic disease

This article introduces important issues related to pain in children with musculoskeletal pain syndromes and rheumatic disease, using juvenile primary fibromyalgia syndrome (JPFS) and juvenile idiopathic arthritis (JIA) as models. A brief summary of the prevalence of pain in healthy children is followed by a summary of existing pain-assessment techniques. The remainder of the article describes the pain experience of children with JPFS and JIA and discusses issues related to pain management.

Juvenile primary fibromyalgia syndrome

Juvenile primary fibromyalgia syndrome (JPFS) is a common musculoskeletal pain syndrome of unknown etiology characterized by widespread persistent pain, sleep disturbance, fatigue, and the presence of multiple discrete tender points on physical examination. Other associated symptoms include chronic anxiety or tension, chronic headaches, subjective soft tissue swelling, and pain modulated by physical activity, weather, and anxiety or stress. Research and clinical observations suggest that JPFS may have a chronic course that impacts the functional status and psychosocial development of children and adolescents. In addition, several factors have been implicated in the etiology and maintenance of JPFS including genetic and anatomic factors, disordered sleep, psychological distress, and familial and environmental influences. A multidisciplinary approach to treatment of JPFS is advocated, including pharmacologic and nonpharmacologic interventions (eg, psychotherapy, aerobic exercise, sleep hygiene).

Stress and rheumatic diseases

This study was done to review the literature concerning the influence of minor and major stress factors on onset and course of rheumatoid arthritis (RA), juvenile chronic arthritis (JCA), systemic lupus erythematosus (SLE), and fibromyalgia syndrome (FS). Major life events and chronic minor stress seem to be very important factors in JCA and are significantly associated with the onset of the disease. With respect to RA and FS, stress may be a provoking factor but the data in the literature are equivocal. However, during the course of the disease, minor stress aggravates SLE, FS, JCA, and RA. Patients with FS and RA may profit from psychological therapies. Optimistic and confronting coping strategies were found most frequently and perceived to be most effective. Very important for psychological function is the social background, especially the functioning of the family is of outstanding importance for clinical and psychological outcome.

Is it juvenile rheumatoid arthritis or fibromyalgia?

For the clinician evaluating adolescents with chronic musculoskeletal pain and fatigue, the distinctions between JRA and FS are clear based on physical examination findings. The two conditions can coexist. For the patient with an initial diagnosis of either JRA or FS whose clinical response to therapy is not in keeping with expectations or physical examination findings or whose clinical course worsens without explanation, reevaluation to determine if FS in the JRA patient has developed or JRA in the FS patient has emerged is warranted. Until clinicians have a better understanding of the intricacies of the neurohormonal and immunologic systems and how they affect somatic symptoms, they can continue to provide patients with a treatment plan based on current knowledge that should minimize patients' discomfort and allow them to have appropriately functional lives.

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.

Psychosocial factors in children with idiopathic musculoskeletal pain: a prospective, longitudinal study

To explore the role of psychosocial factors in the development and persistence of idiopathic musculoskeletal pain (IMP) in children, 23 children with IMP and 52 children with juvenile chronic arthritis (JCA) were compared at first admission to hospital and at 9 y follow-up. Semistructured interviews were performed at both assessments. At first admission, the prevalence of psychiatric diagnoses was high both in patients with IMP and patients with JCA, but patients with IMP more often had pain models, reported more school stress and more often lived with one biological parent. At follow-up, overall psychosocial functioning and level of chronic family difficulties were improved in both groups, but patients with IMP had a higher prevalence of psychiatric diagnoses and more chronic family difficulties and life events than patients with JCA. The persistence of IMP at follow-up was related to pain models, school stress, less parental education and more chronic family difficulties at first admission. Findings support the association between psychosocial factors and childhood IMP.

Pain coping strategies in children with juvenile primary fibromyalgia syndrome: correlation with pain, physical function, and psychological distress

OBJECTIVES

The purpose of this study was twofold: 1) to describe the coping strategies used by children with juvenile primary fibromyalgia syndrome (JPFS), and 2) to examine how pain coping relates to measures of pain, disability/function, psychological distress, and pain behavior.

METHODS

Sixteen children with JPFS completed the Child Version of the Coping Strategies Questionnaire (CSQ-C), the visual analog scale for pain, the McGill Pain Questionnaire, the Fibromyalgia Impact Questionnaire modified for children, the Arthritis Impact Measurement Scales 2, and the Symptom Checklist-90-Revised. Subjects also also underwent pain behavior observation. Pearson's product moment correlations were conducted to examine the relationship of coping to measures of pain and disability.

RESULTS

The Pain Control and Rational Thinking composite factor score on the CSQ-C correlated with measures of pain severity, functional disability, and psychological distress. Results supported the internal reliability of the CSQ-C in assessing pain coping.

CONCLUSIONS

These results suggest that the CSQ-C may provide a reliable measure for assessing variations in pain coping in JPFS patients. Behavioral interventions aimed at increasing the perception of pain control may be beneficial in treating JPFS.

Somatisation in children

This review summarises recent work on somatisation in childhood. Minor physiological dysfunction may play a part in a number of cases and associated psychiatric disorders are commonly though not universally found. Contributory family factors include high rates of health problems and of parental psychological distress and there is some evidence for the role of family modelling and reinforcement of illness behaviour. There is suggestive evidence linking somatisation to emotional closeness in families, to family togetherness around health matters and to anomalies in children's social relationships. Somatisation in children can respond to treatments involving cognitive-behavioural and family techniques as well as to sensitive, psychologically sound advice from paediatricians.
