Fatigue, depression, and social adjustment in chronic fatigue syndrome

Adults with ME/CFS report surprisingly high rates of youth symptoms: A qualitative analysis of patient blog commentary

BACKGROUND

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating chronic illness that impacts pediatric populations.

OBJECTIVE

The current study aimed to better understand adult perceptions of their experiences leading up to their diagnosis of ME/CFS.

METHOD

Patients provided data regarding symptoms of ME/CFS they may have experienced during childhood through a popular community blog forum, with participants interacting via blog comments in real-time and across various geographical locations.

RESULTS

Descriptive analyses indicated that roughly 43% of adult survey participants reported having developed ME/CFS prior to age 18. A standard content analysis of patient blog commentary revealed several themes, such as poor mental health, family pattern/history, healthy childhood preceding sick adulthood, feeling misunderstood, lack of clarity until adulthood, sharing of resources, poor school functioning, isolation/poor social supports, and coping mechanisms.

CONCLUSION

There are unique benefits and insights that can be used by investigators who collaborate with patient organizations as a means of better understanding ME/CFS illness severity, presentation, and lived experiences.

Network analysis of the relationship between negative life events and depressive symptoms in the left-behind children

BACKGROUND

There are 68.77 million left-behind children in China, who are at a great risk of depression associated with negative life events. Our study aims to investigate the most central symptoms of depression in left-behind children and the relationship between depressive symptoms and negative life events using network analysis.

METHOD

A cross-sectional data set (N = 7255) was used, which included children and adolescents aged 7 to 17. Network analysis was used to evaluate: 1) the most central symptoms among the items included in Child Depression Inventory (CDI) of the left-behind children; 2) bridge symptoms between depressive disorder and Adolescent Self-Rating Life Events Check List (ASLEC) of the left-behind children; 3) differences in networks of depressive disorders between left-behind and non-left-behind children, and 4) differences in the network of depression and negative life events between left-behind and non-left-behind children. The stability and centrality indices of the network were also evaluated in the study.

RESULTS

The most central symptoms in the CDI among the left-behind children included self-hatred, crying, fatigue, and sadness. The items with the highest bridge strength centrality in the CDI-ASLEC network included academic stress, discrimination, and school performance decrement. Higher bridge strength values indicate a greater risk of contagion to other communities. The connections in the CDI-ASLEC network are denser in the left-behind children than in non-left-behind children.

LIMITATIONS

The study which was conducted based on cross-sectional data shows that network analysis can only make undirected estimation, but not causal inferences.

CONCLUSIONS

We identified the core symptoms of depression and the bridge symptoms between negative life events and depression in the left-behind children. These findings suggest that more attention should be paid to self-hatred, sadness, and fatigue in the treatment of depression in left-behind children. Intervention for academic stress and discrimination of the left-behind children may help to reduce the contagion of negative life events to depression symptoms.

Health, Wellbeing, and Prognosis of Australian Adolescents with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS): A Case-Controlled Follow-Up Study

Background: The purpose of this study was to follow-up an Australian cohort of adolescents newly-diagnosed with ME/CFS at a tertiary paediatric ME/CFS clinic and healthy controls over a mean period of two years (range 1–5 years) from diagnosis. Objectives were to (a) examine changes over time in health and psychological wellbeing, (b) track ME/CFS symptomatology and fulfillment of paediatric ME/CFS diagnostic criteria over time, and (c) determine baseline predictors of ME/CFS criteria fulfilment at follow-up. Methods: 34 participants aged 13–18 years (25 ME/CFS, 23 controls) completed standardised questionnaires at diagnosis (baseline) and follow-up assessing fatigue, sleep quality and hygiene, pain, anxiety, depression, and health-related quality of life. ME/CFS symptomatology and diagnostic criteria fulfilment was also recorded. Results: ME/CFS patients showed significant improvement in most health and psychological wellbeing domains over time, compared with controls who remained relatively stable. However, fatigue, pain, and health-related quality of life remained significantly poorer amongst ME/CFS patients compared with controls at follow-up. Sixty-five percent of ME/CFS patients at baseline continued to fulfil ME/CFS diagnostic criteria at follow-up, with pain the most frequently experienced symptom. Eighty-two percent of patients at follow-up self-reported that they still had ME/CFS, with 79% of these patients fulfilling criteria. No significant baseline predictors of ME/CFS criteria fulfilment at follow-up were observed, although pain experienced at baseline was significantly associated with criteria fulfilment at follow-up (R = 0.6, p = 0.02). Conclusions: The majority of Australian adolescents with ME/CFS continue to fulfil diagnostic criteria at follow-up, with fatigue, pain, and health-related quality of life representing domains particularly relevant to perpetuation of ME/CFS symptoms in the early years following diagnosis. This has direct clinical impact for treating clinicians in providing a more realistic prognosis and highlighting the need for intervention with young people with ME/CFS at the initial diagnosis and start of treatment.

Parent-child discrepancies in health-related quality of life of children and adolescents with myalgic encephalomyelitis/chronic fatigue syndrome

PURPOSE

Few studies have examined parent-child discrepancies on self-report measures of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) symptomatology and health-related quality of life (HRQOL). The aim of this study was to investigate parent-child reporting discrepancies between a pediatric sample of diagnosed patients with ME/CFS and controls to better understand the role of children and adolescent reporting.

METHOD

Data for this study were drawn from a community-based epidemiological study of pediatric ME/CFS in the Chicagoland area. A total of 147 parent-child dyads (75 pairs with ME/CFS and 72 control pairs) completed measures assessing HRQOL and ME/CFS symptomatology. At the individual level, agreement was assessed using intra-class correlation coefficient (ICC) scores. Agreement was measured at the group level by a comparison of means using paired-sample t-tests.

RESULTS

Intra-class correlations revealed varied agreement in both parent-child pairs of children who met at least one case definition of ME/CFS and in parent-child pairs in the control group.

CONCLUSION

The current study provides support for the existence of discrepancies between parent-child reports of ME/CFS symptomatology and HRQOL measures. Limitations and future directions are discussed.

How common are depression and anxiety in adolescents with chronic fatigue syndrome (CFS) and how should we screen for these mental health co-morbidities? A clinical cohort study

Adolescents with Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) appear to be more likely to experience anxiety and/or depression using Patient Reported Outcome Measures (PROMs). However, we do not know how accurate these are at detecting problems in this patient group given the primary symptom of fatigue. We aimed to accurately determine the prevalence of anxiety/depression using gold-standard diagnostic interviews and evaluate the accuracy of PROMs measuring mood disorders in this patient group. We conducted a cross-sectional epidemiological study in a specialist tertiary paediatric CFS/ME service, England. The participants were164 12-18-year olds with clinician confirmed CFS/ME and their parents. The measures were a semi-structured diagnostic interview, the Kiddie Schedule for Affective Disorders and Schizophrenia, K-SADS, and questionnaires (Revised Children's Anxiety and Depression Scale, RCADS; Spence Children's Anxiety Scale, SCAS; Hospital Anxiety and Depression Scale, HADS). Parents completed the RCADS-P. 35% met the criteria for at least one common mental health problem. 20% had major depressive disorder, and 27% an anxiety disorder, with social anxiety and generalised anxiety being the most common. There was high co-morbidity, with 61% of those who were depressed also having at least one anxiety disorder. The questionnaires were moderately accurate (AUC > 0.7) at detecting clinically significant anxiety/depression, although only the RCADS-anxiety reached the predefined 0.8 sensitivity, 0.7 specificity target. Mental health problems are particularly common amongst adolescents with CFS/ME. Most screening tools were not sufficiently accurate in detecting clinically significant anxiety and depression, so these should be used with care in combination with thorough psychological/psychiatric assessment.

The Prevalence of Pediatric Myalgic Encephalomyelitis/Chronic Fatigue Syndrome in a Community‑Based Sample

BACKGROUND

Most pediatric prevalence studies of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) have been based upon data from tertiary care centers, a process known for systematic biases such as excluding youth of lower socioeconomic status and those less likely to have access to health care. In addition, most pediatric ME/CFS epidemiologic studies have not included a thorough medical and psychiatric examination. The purpose of this study was to determine the prevalence of pediatric ME/CFS from an ethnically and sociodemographically diverse community-based random sample.

METHOD

A sample of 10,119 youth aged 5-17 from 5622 households in the Chicagoland area were screened. Following evaluations, a team of physicians made final diagnoses. Youth were given a diagnosis of ME/CFS if they met criteria for three selected case definitions. A probabilistic, multi-stage formula was used for final prevalence calculations.

RESULTS

The prevalence of pediatric ME/CFS was 0.75%, with a higher percentage being African American and Latinx than Caucasian. Of the youth diagnosed with ME/CFS, less than 5% had been previously diagnosed with the illness.

CONCLUSIONS

Many youth with the illness have not been previously diagnosed with ME/CFS. These findings point to the need for better ways to identify and diagnose youth with this illness.

Depressive symptoms in adolescents with chronic fatigue syndrome (CFS): Are rates higher than in controls and do depressive symptoms affect outcome?

INTRODUCTION

Previous research has indicated that co-morbid depression is common in adolescents with chronic fatigue syndrome (CFS).

OBJECTIVES

We sought to compare the characteristics of depressive symptoms in adolescents with CFS to those of healthy controls (HCs) and illness controls (adolescents with asthma).

DESIGN

Case-control study nested within a prospective clinical cohort.

METHODS

A total of 121 adolescents with CFS who attended an initial assessment at two specialist CFS units completed the Children's Depression Inventory (CDI). Their responses were compared to 80 HCs and 27 adolescents with asthma (illness controls). The clinical cohort of adolescents with CFS completed questionnaires at assessment, and those who were seen subsequently for treatment at the CFS unit (68%) completed the measures again at their first treatment session.

RESULTS

CFS participants scored significantly higher on all the depression subscales than participants with asthma and HCs. Depression score explained 11% of the variance in subsequent fatigue, but only 1.9% of the variance in physical functioning. Depression score also explained most (68%) of the variance in subsequent depression.

CONCLUSION

Depressive symptoms are more prominent in adolescents with CFS than in HCs or illness controls. These symptoms also appear to remain over time during a naturalistic follow-up where no treatment was provided. This highlights the need for further research into depression in CFS, including stratifying treatment outcomes by depression status to determine what is effective at addressing these symptoms.

The presence of co-morbid mental health problems in a cohort of adolescents with chronic fatigue syndrome

OBJECTIVE

To report on the prevalence of mental health disorders in adolescents with chronic fatigue syndrome (CFS) and to compare the diagnoses identified by a brief clinician-administered psychiatric interview with self-report screening questionnaires.

DESIGN

Cross-sectional study.

SETTING

Consecutive attenders to specialist CFS clinics in the United Kingdom.

PATIENTS

N = 52 adolescents, age 12-18 years with CFS.

MEASURES

Self-report questionnaires and a brief structured psychiatric diagnostic interview, administered by a researcher.

RESULTS

On the psychiatric interview, 34.6% met a diagnosis of major depressive disorder and 28.8% had an anxiety disorder. Of these, 15% had co-morbid anxiety and depression. Those with a depression diagnosis reported significantly greater interference on the school and social adjustment scale. They also scored significantly higher on trait anxiety, but not on state anxiety. There were no differences between those who had an anxiety disorder and those who did not on fatigue, disability or depressive symptoms. Children's Depression Inventory (CDI) score was associated with a depression diagnosis on the psychiatric interview. However, neither the state nor the trait subscale of the State-Trait Anxiety Inventory (STAI) was associated with an anxiety diagnosis.

CONCLUSION

Clinicians should assess for the presence of anxiety and depressive disorders in adolescents with CFS using a validated psychiatric interview. Treatment should be flexible enough to accommodate fatigue, depression and anxiety. Transdiagnostic approaches may suit this purpose. Goals should include pleasurable activities particularly for those who are depressed.

Chronic fatigue syndrome in childhood: seven-year follow-up study

This study explores the outcome and longer-term sequelae of suffering chronic fatigue syndrome in childhood. Ten such children, ranging from 10 to 16 years of age at diagnosis, were followed up into adulthood, an average of seven years. Most were completely well or markedly improved (seven of nine). Only children fully engaged in therapy made a total recovery. However, respondents felt medical staff did not believe their symptoms and that rehabilitative strategies were unhelpful. No physical or mental illness was subsequently diagnosed to account for the original symptom presentation. Childhood sufferers maintained the same pattern of symptoms as adults. Depressive symptomatology was present in two cases. The overall longer-term prognosis for children suffering chronic fatigue syndrome is good. A successful doctor-patient relationship is essential to improve compliance with management plans.

Chronic fatigue syndrome in children and adolescents

General practitioners in a south London health authority were sent a questionnaire about their experience and views concerning the treatment of childhood chronic fatigue syndrome. Most thought childhood chronic fatigue syndrome had a significant psychological component, but opinion was divided over referral to a psychiatrist. The involvement of self-help organisations was supported but the place of rest and exercise unclear. The optimum primary care management of childhood chronic fatigue syndrome needs to be established.

Management of chronic fatigue syndrome in children

Certain areas of child and adolescent mental health generate a degree of polarised debate, both within and outside the profession. Media attention, the development of self-help groups and the Internet lead to the publishing of papers and opinion, which exist alongside peer-reviewed research and evidence-based medicine. Parents reading such material may find it hard to know what advice is best. One area that falls into this category is chronic fatigue syndrome (CFS).

Measuring School Functioning in Students With Chronic Fatigue Syndrome: A Systematic Review

BACKGROUND

It is often surmised that school functioning is significantly impacted in chronic fatigue syndrome (CFS); however, how this phenomenon manifests itself has rarely been characterized.

METHODS

This systematic review synthesized and critically appraised methods, constructs, and instruments used to assess school functioning in students with CFS. Searches were conducted in electronic databases (CINAHL, MEDLINE, PubMed, ERIC, and PsycINFO) to locate empirical studies that measured school functioning in children and adolescents with CFS.

RESULTS

A total of 36 papers met the inclusion criteria. By far the most commonly reported school functioning construct measured related to school attendance. This was followed by academic functioning, achievement motivation, and educational services received. Little consistency was found in the measurement of these constructs across studies.

CONCLUSIONS

The current review revealed that the school experiences of children and adolescents with CFS have rarely been characterized beyond school absenteeism. Improvements in current assessment methods are required to comprehensively understand the impact of CFS on school functioning. Completely understanding the multiple aspects of school functioning will help to inform targeted strategies to optimize educational outcomes for students with CFS.

Same, Same But Different? Cognitive Behavioural Treatment Approaches for Paediatric CFS/ME and Depression

BACKGROUND

Approximately one in three children and young people with chronic fatigue syndrome (CFS/ME) also have probable depression. Cognitive behaviour therapy (CBT) has a growing evidence base as an effective treatment approach for CFS/ME and for depression in this population.

AIMS

Given the high degree of co-morbidity, this discussion paper aims to compare and contrast CBT for CFS/ME and CBT for depression in children and young people.

METHOD

The existing literature on CBT for depression and CBT for CFS/ME, in relation to children and young people was reviewed.

RESULTS

Whilst there are commonalities to both treatments, the cognitive behavioural model of CFS/ME maintenance includes different factors and has a different emphasis to the cognitive behavioural model of depression, resulting in different intervention targets and strategies in a different sequence.

CONCLUSIONS

A collaborative, formulation-driven approach to intervention should inform the intervention targets and treatment strategies.

Treatment for paediatric chronic fatigue syndrome or myalgic encephalomyelitis (CFS/ME) and comorbid depression: a systematic review

OBJECTIVES

At least 30% of young people with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) also have symptoms of depression. This systematic review aimed to establish which treatment approaches for depression are effective and whether comorbid depression mediates outcome.

SETTING

A systematic review was undertaken. The search terms were entered into MEDLINE, EMBASE, PsycInfo and the Cochrane library.

PARTICIPANTS

Inclusion and exclusion criteria were applied to identify relevant papers. Inclusion criteria were children age <18, with CFS/ME, defined using CDC, NICE or Oxford criteria, and having completed a valid assessment for depression.

RESULTS

9 studies were identified which met the inclusion criteria, but none specifically tested treatments for paediatric CFS/ME with depression and none stratified outcome for those who were depressed compared with those who were not depressed. There is no consistent treatment approach for children with CFS/ME and comorbid depression, although cognitive-behavioural therapy for CFS/ME and a multicomponent inpatient programme for CFS/ME have shown some promise in reducing depressive symptoms. An antiviral medication in a small scale, retrospective, uncontrolled study suggested possible benefit.

CONCLUSIONS

It is not possible to determine what treatment approaches are effective for depression in paediatric CFS/ME, nor to determine the impact of depression on the outcome of CFS/ME treatment. Young people with significant depression tend to have been excluded from previous treatment studies.

Chronic Fatigue Syndrome in Children and Adolescents: A Review Article

Clinicians have been describing individuals with chronic fatigue states for over 100 years, although chronic fatigue syndrome is often regarded as a modern disease. The aetiology of chronic fatigue syndrome is uncertain. For young individuals with chronic fatigue syndrome there are neither reliable prevalence figures nor scientific evidence concerning the effectiveness of treatments. Information obtained from research into adult individuals with chronic fatigue syndrome may be helpful but is not necessarily directly applicable to children and adolescents. Developmental factors and the influence of other family members on the course of the disorder in young sufferers should be considered. The uncertainties surrounding chronic fatigue syndrome should not deter child and adolescent mental health workers from becoming involved in the assessment and management of individual patients. The mainstay of treatment is rehabilitation with an emphasis on gradually increasing activities. Considerable attention will need to be given to engaging the young people and their families and working effectively with a multidisciplinary team. If mental health workers do not become involved in treating young people with chronic fatigue syndrome there is a risk that psychological factors will not be addressed and that chronic functional impairment will ensue.

Management advice for children with chronic fatigue syndrome: a systematic study of information from the internet

Objectives:Parents often present practising clinicians who see children with chronic fatigue syndrome with printouts from the internet. These are then brought into the discussion about the management and aetiology of this debilitating condition. We set out to systematically study the information on the internet on this subject and to explore the diversity of advice in relation to current research knowledge.

Method:Systematic search by means of the internet browser Netscape Navigator and search engines AltaVista and Yahoo! Advice about levels of rest, exercise, medication, psychological interventions and suggestions about return to school is critically compared with current research evidence.

Results:Thirteen websites were accessed. All have some treatment advice. Six offer conflicting advice about levels of rest, with two suggesting large amounts of rest, two suggesting some rest and two suggesting graded exercise. Nine suggest medications (with a wide variety of pharmacological activities) despite the lack of research evidence showing a significant contribution from medication. Four suggest psychological treatments but some advise that it is unnecessary despite the established evidence in chronic fatigue (and other chronic illnesses) that appropriate psychological treatments are helpful. There are a wide variety of differing diets recommended.

Conclusions:Few websites provide useful management advice. Advice offered is often in conflict. Some of the advice is either contrary to current research evidence or not supported by it. This raises concerns about inaccurate information reaching families who have a child with chronic fatigue syndrome, with potentially damaging consequences. This suggests a need for a debate about the availability and validation of health related information on the internet.

Predictors of Post-Infectious Chronic Fatigue Syndrome in Adolescents

This study focused on identifying risk factors for adolescent post-infectious chronic fatigue syndrome (CFS), utilizing a prospective, nested case–control longitudinal design in which over 300 teenagers with infectious mononucleosis (IM) were identified through primary care sites and followed. Baseline variables that were gathered several months following IM, included autonomic symptoms, days in bed since IM, perceived stress, stressful life events, family stress, difficulty functioning and attending school, family stress, and psychiatric disorders. A number of variables were predictors of post-infectious CFS at six months; however, when autonomic symptoms were used as a control variable, only days spent in bed since mono was a significant predictor. Step-wise logistic regression findings indicated that baseline autonomic symptoms as well as days spent in bed since mono, which reflect the severity of illness, were the only significant predictors of those who met CFS criteria at six months.

An approach to persons with chronic fatigue syndrome based on the model of human occupation: part one, impact on occupational performance and participation

Chronic fatigue syndrome (CFS) is a prevalent and disabling condition that involves six or more months of unexplained fatigue severe enough to interfere with previous levels of occupational, educational, and/or social performance. The fatigue is accompanied by at least four of eight additional physical and cognitive symptoms (Fukuda et al., 1994). This paper conceptualizes the multiple factors that affect occupational adaptation in persons with CFS. The Model of Human Occupation (MOHO) if used as a framework for understanding the synergistic and evolving relationships between motivation, roles, habits, performance capacities, and the environment as they influence individuals with CFS. Examples from the literature, autobiographical accounts, and from practice experience are used to illustrate the experience and impact of CFS on everyday life.

Patient-reported Pediatric Quality of Life Inventory™ 4.0 Generic Core Scales in pediatric patients with attention-deficit/hyperactivity disorder and comorbid psychiatric disorders: feasibility, reliability, and validity

OBJECTIVES

The primary objective of the study was to evaluate the feasibility, reliability, and validity of the Pediatric Quality of Life Inventory™ (PedsQL) 4.0 Generic Core Scales as a patient self-reported health-related quality of life measurement instrument in pediatric patients with attention-deficit/hyperactivity disorder (ADHD) and physician-diagnosed comorbid psychiatric disorders being seen in a pediatric psychiatric clinic. The secondary objective was to evaluate parent proxy-reported PedsQL in this population.

METHODS

One hundred seventy-nine children with ADHD and comorbid psychiatric disorders ages 5 to 18 years and 181 parents completed the PedsQL 4.0 Generic Core Scales and parents also completed the Vanderbilt ADHD Diagnostic Rating Scales. Known-groups discriminant validity comparisons were made between the sample of pediatric patients with ADHD and comorbid psychiatric disorders and healthy, cancer, and type 1 diabetes samples.

RESULTS

The PedsQL evidenced minimal missing responses for patient self-report and parent proxy-report (0.2% and 0.5%, respectively), demonstrated no significant floor or ceiling effects, and achieved excellent reliability for the Total Scale Score (α = 0.85 patient self-report, 0.92 parent proxy-report). Pediatric patients with ADHD and comorbid psychiatric disorders and their parents reported statistically significantly worse PedsQL scores than healthy children, with large effect sizes across all domains, supporting known-groups discriminant validity. Pediatric patients with ADHD and comorbid psychiatric disorders and their parents reported worse PedsQL scores compared to pediatric patients with cancer and diabetes with the exception of physical health, in which pediatric cancer patients manifested lower physical health, indicating the relative severe impact of ADHD and comorbid psychiatric disorders. More severe ADHD symptoms were generally associated with more impaired PedsQL scores, supporting construct validity.

CONCLUSIONS

These data demonstrate the feasibility, reliability, and validity of patient self-reported PedsQL 4.0 Generic Core Scales in this high risk population of pediatric patients and highlight the profound negative impact of ADHD and comorbid psychiatric disorders on generic health-related quality of life, comparable to or worse than serious pediatric chronic physical diseases.

Physical and functional impact of chronic fatigue syndrome/myalgic encephalomyelitis in childhood

OBJECTIVE

The aim of this study was to compare self-reported and parent-reported quality of life for a group of pediatric patients with chronic fatigue syndrome (CFS)/myalgic encephalomyelitis (ME) and age- and gender-matched healthy control children, to determine the extent of functional and physical impairment.

METHODS

The Child Health Questionnaire was completed by 25 children with CFS/ME, who were recruited throughout the United Kingdom, and by 23 age-, gender-, and Tanner scale-matched control children. In addition, patients were asked questions about the background to their illness (ie, precipitating factors), the status of their illness, and school attendance.

RESULTS

The median illness duration for patients was 3 years. Sixty-eight percent of the children said that their illness developed quickly, and the illness had an infectious onset for 88%. Only 1 child (4%) attended school full-time, whereas 12 (48%) attended school part-time and 8 (32%) received home tuition only. Children with CFS/ME scored significantly lower for 10 of 14 Child Health Questionnaire concepts; the lowest scores were observed for global health (scores of 21.4 and 84.1 for patients and control subjects, respectively; P < .0001) and role/social limitations attributable to physical health problems (scores of 24.9 and 100, respectively; P < .0001). Quality of life for the children with CFS/ME compared unfavorably with previously published results for pediatric patients with type 1 diabetes mellitus or asthma.

CONCLUSION

The quality of life of children with CFS/ME was profoundly reduced, compared with that of their healthy counterparts.

Chronic fatigue syndrome in adolescents: do parental expectations of their child's intellectual ability match the child's ability?

OBJECTIVE

This cross-sectional study aimed to measure the discrepancy between actual and perceived IQ in a sample of adolescents with CFS compared to healthy controls. We hypothesized that adolescents with CFS and their parent would have higher expectations of the adolescent's intellectual ability than healthy adolescents and their parent.

METHODS

The sample was 28 CFS patients and 29 healthy controls aged 11-19 years and the parent of each participant. IQ was assessed using the AH4 group test of general intelligence and a self-rating scale which measured perceived IQ.

RESULTS

Parents' perceptions of their children's IQ were significantly higher for individuals with CFS than healthy controls.

CONCLUSIONS

High expectations may need to be addressed within the context of treatment.

Relationship between disabling fatigue and depression in children: genetic study

BACKGROUND

Medically unexplained disabling fatigue in young people is familial and frequently associated with depressed mood.

AIMS

To examine the degree of sharing of genetic and environmental influences on the symptoms of depression and fatigue in this age group.

METHOD

The parents of twins aged 8-17 years, derived from a population-based register, completed a questionnaire regarding lifetime-ever disabling fatigue in both twins. Twins aged 11 years or over completed the Mood and Feelings Questionnaire. The genetic and environmental influences on fatigue and the relationship with depression were examined using bivariate genetic analysis.

RESULTS

Parent-rated data were obtained for 1468 twin pairs (65%) and self-rated data from 930 older twin pairs (58%). Bivariate analysis of fatigue and depression suggested that genetic and environmental influences on disabling fatigue were mainly specific to fatigue.

CONCLUSIONS

Unexplained disabling fatigue in childhood is substantially familial and has mainly an independent aetiology from depression.

The management of children with chronic fatigue syndrome-like illness in primary care: a cross-sectional study

BACKGROUND

Most studies on children with chronic fatigue syndrome (CFS)/myalgic encephalomyelitis (ME) have been undertaken in tertiary care and little is known about their management in primary care.

AIM

To describe the characteristics of patients aged 5-19 years with CFS-like illness in primary care and to examine how GPs investigate and manage patients.

DESIGN OF STUDY

Descriptive retrospective questionnaire study.

SETTING

Sixty-two UK GP practices in the MRC General Practice Research Framework (GPRF).

METHOD

One hundred and twenty-two practices were approached; 62 identified 116 patients consulting a GP with severe fatigue lasting over 3 months. Practice nurses and GPs completed questionnaires from medical notes and patients completed postal questionnaires.

RESULTS

Ninety-four patients were considered by a clinical panel, blind to diagnosis, to meet the Oxford CFS criteria with a fatigue duration of 3 months. Seventy-three per cent were girls, 94% white, mean age was 12.9 years and median illness duration 3.3 years. GPs had principal responsibility for 62%. A diagnosis of CFS/ME was made in 55%, 30% of these within 6 months. Fifty per cent had a moderate illness severity. Paediatric referrals were made in 82% and psychiatric referrals in 46% (median time of 2 and 13 months respectively). Advice given included setting activity goals, pacing, rest and graded exercise.

CONCLUSIONS

Patient characteristics are comparable to those reported in tertiary care, although fewer are severe cases. GPs have responsibility for the majority of patients, are diagnosing CFS/ME within a short time and applying a range of referral and advice strategies.

Children and adolescents with Chronic Fatigue Syndrome in non-specialist settings: beliefs, functional impairment and psychiatric disturbance

BACKGROUND

Adolescents with Chronic Fatigue Syndrome (CFS) seen in specialist centres have substantial psychological and functional impairment. Beliefs about activity levels may be important in the development of CFS.

METHOD

The aim was to investigate psychological and functional impairment, and beliefs in children and adolescents with CFS recruited from non-specialist services. A total of 30 such individuals participated, and 30 young people with Inflammatory Bowel Disease (IBD) formed the comparison group.

RESULTS

Emotional symptoms and disorder were high in both groups. In all, 50% of those with CFS and 30% with IBD reached the threshold for emotional disorder according to the Strengths and Difficulties Questionnaire (SDQ) parent report, although this difference did not reach statistical significance. Participants with CFS scored statistically significantly higher on measures of functional impairment, including school non-attendance, compared to those with IBD. According to questionnaire responses, those with CFS were statistically significantly more likely to favour rest rather than exercise compared to those with IBD. Comparison of parental beliefs did not show such a difference.

CONCLUSIONS

These young people with CFS were at high risk of psychiatric disorder. They were substantially disabled when compared to individuals with a known chronic illness. Also, as a group, they were characterised by a preference for rest rather than exercise.

Impairment and coping in children and adolescents with chronic fatigue syndrome: a comparative study with other paediatric disorders

BACKGROUND

Functional impairment is a key feature of chronic fatigue syndrome (CFS) of childhood.

AIM

To compare impairment, illness attitudes and coping mechanisms in childhood CFS and in other paediatric disorders.

METHOD

Participants were 28 children and adolescents with CFS, 30 with juvenile idiopathic arthritis (JIA) and 27 with emotional disorders (ED). The measures used were interviews with children and parents, with detailed enquiry on impairment, including the Functional Disability Inventory (FDI), Illness Attitudes Scales (IAS), and Kidcope to measure coping styles in relation to common problems, illness and disability.

RESULTS

Children with CFS reported significantly more illness impairment, especially in school attendance, than those with JIA and ED. They had higher 'worry about illness' scores on the IAS. On the Kidcope they named school issues (work, expectations, attendance) as illness- or disability-related problems more than the other two groups. Fewer CFS participants reported using problem solving as a strategy to cope with illness and disability than with other problems in their lives. More in the CFS than in the JIA group used emotional regulation to cope with illness and disability. Fewer in the CFS than in the ED groups used social withdrawal to cope with illness and self-criticism for disability, but more used resignation to cope with disability.

CONCLUSION

Severe illness-related impairment, particularly through school non-attendance, and high levels of illness-related school concerns appear specific to CFS. CFS may also have characteristically high levels of generalised illness worry and particular styles of coping with illness and disability.

Chronic fatigue syndrome in children: a cross sectional survey

BACKGROUND

Chronic fatigue syndrome (CFS) in children is a controversial diagnosis with unclear aetiology, ill defined but likely increasing incidence, and debatable clinical management options. However these children experience real and considerable suffering. Appropriate research in this clinical population is sparse and usually occurs in tertiary referral units.

METHODS

Cross sectional survey of 36 children attending a GP specialist interest clinic in southeast England.

RESULTS

Patient sociodemographics and clinical morbidity were largely comparable to the literature from tertiary referral research centres. Some prognostic indicators for adults did not readily transfer to this younger age group, although several children had a positive family psychiatric history. Receiving treatment was associated with increased school attendance, but one third of subjects obtained no qualifications. Return to normal health or significant overall improvement was reported by 29/36 subjects.

CONCLUSIONS

The outcomes in this setting are favourable and comparable to those seen in a controlled setting; this study supports the concept that the prognosis for CFS in children and adolescents is generally good. However, the impact of the illness is significant and this is perhaps most evident in terms of education. Current methods of reporting educational outcomes in the literature are varied and merit development of standardised tools.

Comparative study of anxiety, depression, somatization, functional disability, and illness attribution in adolescents with chronic fatigue or migraine

OBJECTIVE

To compare adolescents with migraine, unexplained profound chronic fatigue of >6 months duration, and normal school controls on measures of anxiety, depression, somatization, functional disability, and illness attribution.

METHODS

Adolescents referred to Children's Hospital and Regional Medical Center for behavioral treatment of migraine (n = 179) or evaluation of chronic fatigue (n = 97) were compared with a group of healthy controls of similar age and sex from a middle school (n = 32). Subjects completed the Spielberger State-Trait Anxiety Inventory-Trait Form, the Children's Depression Inventory, the Childhood Somatization Inventory, and estimated the number of school days missed in the past 6 months because of illness. Migraine and fatigued subjects completed an illness attribution questionnaire.

RESULTS

Subjects in the 3 groups were 56% to 70% female and ranged from 11 years old to 18 years old with a mean age of 14.0 +/- 2.0. Forty-six of the 97 chronically fatigued adolescents met 1994 Centers for Disease Control and Prevention (CDC) criteria for chronic fatigue syndrome (CDC-CFS), while 51 had idiopathic chronic fatigue syndrome (I-CFS) that did not meet full CDC criteria. Adolescents with migraine had significantly higher anxiety scores than those with I-CFS or controls and higher somatization scores than controls. Adolescents with CDC-CFS had significantly higher anxiety scores than those with I-CFS or controls, and higher depression and somatization scores than all other groups. There were significant differences between all groups for school days missed with CDC-CFS more than I-CFS more than migraine more than controls. Parents of adolescents with unexplained I-CFS had significantly lower attribution scores relating illness to possible psychological or stress factors than parents of adolescents with CDC-CFS or migraine.

CONCLUSIONS

Adolescents referred to an academic center for evaluation of unexplained chronic fatigue had greater rates of school absenteeism than adolescents with migraine or healthy controls. Those meeting CDC-CFS criteria had higher anxiety scores than controls and higher depression and somatization scores than migraineurs or controls. Parents of adolescents with I-CFS were less likely to endorse psychological factors as possibly contributing to their symptoms than parents of adolescents with CDC-CFS or migraine.

Chronic fatigue syndrome: successful outcome of an intensive inpatient programme

OBJECTIVE

To study the outcome of adolescents with chronic fatigue syndrome (CFS) following an intensive multi-disciplinary inpatient programme.

METHODS

A follow-up questionnaire was distributed to all 57 adolescents who had completed the CFS inpatient programme at the Austin and Repatriation Medical Centre.

RESULTS

Forty-two adolescents (74%) returned follow-up questionnaires. Immediately following the programme and up to five years after the programme, the majority of participants had returned to school and were functioning better in terms of physical activity and social interactions as compared with before the programme. Before the programme, 94% of adolescents were attending school half-time or less. Up to 5 years after the programme, 78% of adolescents were attending school full-time or with occasional absences only.

CONCLUSIONS

A multidisciplinary inpatient programme for CFS was successful in helping to rehabilitate this group of adolescents who were significantly incapacitated prior to entering the inpatient programme.

Annotation: Chronic Fatigue Syndrome in children and adolescents

BACKGROUND

Over the past two decades Chronic Fatigue Syndrome (CFS) of childhood has gained increasing prominence. A number of clinical reports and case-control studies have examined the nature of the disorder, its associations, response to treatment and outcome.

METHOD

A review of publications on childhood CFS was undertaken and reference to work on adult CFS made. Most studies on childhood CFS have been on markedly affected children attending specialist pediatric clinics and very little is known about the condition as it presents in the community or to general medical services.

RESULTS

The main symptom is fatigue in association with a variety of physical symptoms and with marked and prolonged functional impairment. CFS is commonly reported as being brought on by acute infections. Co-morbid psychiatric (usually mood) disorders are present in at least a half. Personality problems and health attitudes have been described as possible predisposing and maintaining factors. Clinical reports indicate that family work focused on engagement and on a rehabilitation programme (including graded increasing activity and treatment of psychiatric co-morbidity) can help even the more severely impaired children. Recovery may be expected in over two-thirds.

CONCLUSIONS

CFS presents as a distinct, markedly impairing disorder of childhood. In its severe form, it is often associated with mood disorders. Further research into milder forms and into the efficacy of different treatment interventions is specially needed.

Coping and illness cognitions: chronic fatigue syndrome

The chronic fatigue syndrome (CFS) is described, and research on coping with this illness reviewed and analysed. CFS is a severely disabling illness of unknown etiology, which has occurred in epidemic forms all over the world. However, the number of sufferers has dramatically increased over previous years. The heterogeneous symptomatology of CFS was reviewed, and diagnostic criteria were discussed. The difficulty in establishing causality was emphasized. An interaction of factors appears most likely to be associated with illness onset and maintenance. As the mediating factor could be sufferers' coping behavior, the existing coping literature was reviewed. There might be an association between coping and physical and psychological well-being. Finally, recommendations are made for longitudinal research on coping and coping effectiveness, and for the development of therapeutic interventions.

Psychological adjustment of adolescent girls with chronic fatigue syndrome

OBJECTIVE

To examine psychosocial problems and adaptation of adolescent girls with chronic fatigue syndrome (CFS).

METHODOLOGY

Thirty-six adolescent girls with CFS (mean age: 15.2 years; mean syndrome duration: 19.7 months) who fulfilled the criteria of the Centers for Disease Control and Prevention were examined by interviews regarding premorbid problems and by questionnaires regarding psychosocial functioning and distress, psychological attitudes, and coping resources. Data were compared with normative data.

RESULTS

Of the adolescents, 86.1% reported 1 or more premorbid problems (58.3% physical, 38.9% psychological, and 52.8% familial). Normal adjustment was reported for psychosocial self-esteem, social abilities, and attentional abilities. High adjustment to adult social standards of behavior was found, but low perceived competence in specific adolescent domains, such as athletic ability, romance, and participation in recreational activities. The girls reported predominantly internalizing problems. Normal achievement motivation, no debilitating fear of failure, and high internal locus of control were observed. Palliative reaction patterns and optimism were predominantly used as coping strategies.

CONCLUSIONS

The large number of premorbid problems suggests a possible contributing factor to the onset of the syndrome, although there were no reference data of healthy adolescents. In distinct domains of psychosocial adjustment, the adolescent girls with CFS showed strengths such as adequate self-esteem and scholastic and social abilities, and weaknesses such as low competence in adolescent-specific tasks and internalizing distress, which may partly be explained by syndrome-specific somatic complaints. The use of optimistic and palliative reaction patterns as coping strategies in this patient group indicates that the patients with CFS seem to retain an active and positive outlook on life, which may result in a rather adequate psychological adaptation to the syndrome, but also in maintenance of the syndrome by exceeding the physical limits brought about by the CFS. Our results on adjustment and coping strategies may be helpful to implement (individual) rehabilitation programs.

Fatigue in children and adolescents with cancer: evolution of a program of study

OBJECTIVES

To describe the development of a research program focused on cancer-related fatigue in children and adolescents and the resulting definition and model.

DATA SOURCES

Research studies, review articles, and clinical examples.

CONCLUSIONS

Fatigue has been identified by children and adolescents who are receiving treatment for cancer as one of the most distressing treatment-related symptoms they experience, yet fatigue is rarely assessed by health professionals and infrequently reported by patients or their parents.

IMPLICATIONS FOR NURSING PRACTICE

An improved understanding of the contributory and alleviating factors that cause fatigue in this patient population will provide them with greater comfort during treatment for cancer.

The course of severe chronic fatigue syndrome in childhood

Little has been reported on prognostic indicators in children with chronic fatigue syndrome (CFS). We used interviews with children and parents, a mean of 45.5 months after illness onset, to follow up 25 cases of CFS referred to tertiary paediatric psychiatric clinics. At its worst, the illness had been markedly handicapping (prolonged bed-rest and school absence in two-thirds); mean time out of school was one academic year. Two-thirds, however, had recovered and resumed normal activities--mean duration of illness to recovery/assessment 38 months--and none had developed other medical conditions. Recovery was associated with specific physical triggers to the illness, with start of illness in the autumn school term and with higher socioeconomic status. Severe fatigue states in children can cause serious and longlasting handicap but most children recover.

Psychiatric adjustment in adolescents with a history of chronic fatigue syndrome

OBJECTIVE

To ascertain psychiatric adjustment in youngsters with a history of childhood chronic fatigue syndrome (CFS).

METHOD

Subjects were 25 children and adolescents with CFS who were seen in tertiary pediatric/psychiatric clinics (mean age 15.6 years, seen a mean of 45.5 months after illness onset; 17 subjects had recovered and 8 were still ill) and 15 healthy matched controls. Youngsters and their parents (usually mothers) were interviewed and completed questionnaires. Instruments used included the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS), the Child Behavior Checklist (CBCL), and the Harter Self-Esteem Questionnaire.

RESULTS

At assessment, psychiatric disorders (mainly anxiety and depressive disorders) were present in half the subjects with a history of CFS, a rate significantly higher than in healthy controls. On the CBCL youngsters with a history of CFS had an excess of psychological symptoms and decreased social competence. On the Harter Self-Esteem Questionnaire they reported reduced self-esteem, especially in social competence. Anxiety disorders were significantly more common in recovered subjects than in those with active CFS illness status.

CONCLUSIONS

Psychiatric disorders were found to be increased in adolescents with a history of severe CFS; CFS may enhance the risk for or share common predisposing factors with anxiety disorders.

Comparing patient, parent, and staff descriptions of fatigue in pediatric oncology patients

Fatigue in children and adolescents with cancer is a disruptive symptom meriting clinical intervention by nurses, but has eluded definition, measurement, and intervention. Fatigue in these patients exists within a greater context of illness, treatment, and child and family development. Any effort to define, measure, and intervene with fatigue needs to take into consideration the major components of these children and adolescents' treatment context. The purpose of this descriptive study was to learn from three perspectives (patient, parent, and staff) how fatigue is identified and defined in 7- to 12-year-old children and in 13- to 18-year-old adolescents with cancer, and what factors contribute to or alleviate this fatigue. To elicit this information, separate focus groups were conducted with patients, parents, and staff at two pediatric oncology centers. Resulting interview data were analyzed using pragmatic and semantic content analysis techniques and the Wilson concept analysis process. Findings clearly indicated that children, adolescents, parents, and staff define patient fatigue differently. The conceptual definition from the child data emphasizes the physical sensation of the fatigue; alternating and at times merging physical and mental tiredness are emphasized in the adolescent's definition. Parents and staff view themselves as responsible for alleviating patient fatigue; patients viewed rest and distraction as their primary sources of improving fatigue. The conceptual definitions of fatigue as rendered by our three groups of participants can assist pediatric oncology patients, their parents, and staff in identifying fatigue. Factors identified by these participants as contributing or alleviating fatigue could be the basis for future interventions designed to reduce fatigue in pediatric oncology patients.

Psychological symptoms in chronic fatigue and juvenile rheumatoid arthritis

OBJECTIVE

To determine if psychological morbidity in youth with chronic fatigue is caused by the stress of coping with a chronic illness.

STUDY DESIGN

Case-control study comparing pediatric patients with debilitating chronic fatigue and matched subjects with juvenile rheumatoid arthritis, a chronic medical illness with similar functional sequelae.

SETTING

Pediatric Infectious Diseases Clinic and Juvenile Rheumatoid Arthritis Clinic of Kosair Children's Hospital.

PARTICIPANTS

Nineteen children and adolescents with debilitating chronic fatigue and 19 age- and sex-matched peers with juvenile rheumatoid arthritis. Outcome. Structured Interview, Kaufman Brief Intelligence Test, Child Behavior Checklist, and Youth Self-Report.

RESULTS

Intellectual functioning on the Kaufman Brief Intelligence Test Composite was average (103, standard score) for both groups. Pediatric patients with chronic fatigue had higher levels of internalizing psychological distress than patients suffering from juvenile rheumatoid arthritis, despite the fact that both groups had a similar pattern of decline in social and physical activities. Duration of illness did not explain the difference in psychological symptoms.

CONCLUSIONS

Psychological factors may play a more active role in debilitating chronic fatigue in pediatric patients than can be explained by the stress of coping with a similar chronic, non-life-threatening illness.

Fatigue in children and adolescents with cancer

Fatigue is a common symptom found in the adult oncology literature. However, little is known about its occurrence, causes, conceptual and operational definitions, and effective interventions in children and adolescents with cancer. The purpose of this study was to define and describe fatigue experienced by children and adolescents receiving treatment for cancer. A focus group approach was used to reveal the contextual understanding of fatigue through discussions. Eleven focus groups were convened during a 2-month period at two major children's cancer centers. Twenty-nine children participated in the focus groups: 14 were 7 to 12 years of age and 15 were 13 to 16 years of age. Focus groups were held separately for each age group, lasted from 30 to 45 minutes, and were audiotaped. The audiotapes were transcribed verbatim, and Ethnograph software was used to number the data to sort and code the information. Researchers at both study sites coded the data independently within the context of the unit of analyses, which, in this study, were the study questions. Codes and descriptions were developed for the definitions of fatigue, causes of fatigue, and what helps. Eight codes emerged from the children groups and 12 from the adolescent groups to define fatigue. Six codes were developed from the children groups and 12 from the adolescent groups to describe causes of fatigue. Three codes from the children groups and eight from the adolescent groups described what helps. This study is the first to evaluate fatigue as a symptom in children and adolescents with cancer. Findings from this study will provide the foundation for developing a conceptual model for cancer-related fatigue in children and adolescents.

Psychosomatic problems and stress in adolescence

Psychosomatic problems are common in adolescents, and stress frequently plays a role in their development and maintenance. Armed with an understanding of the stressors experienced by adolescents, the individual's vulnerabilities and competencies and their level of social support, the physician can systematically assess each of these factors. Once the assessment is complete, a management plan can be formulated to address the particular psychosomatic problem. Symptom relief, stress reduction, and promotion of competence are important interventions that can be initiated by the primary care physician. When referrals are made for counseling and other stress management techniques, the primary care physician should maintain contact with the patient and family and remain an integral part of the management team. Incorporating brief discussions about the potential role of stress in health and illness into anticipatory guidance sessions may also help prevent the development of psychosomatic problems in adolescents.

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.

Chronic fatigue syndrome or affective disorder? Implications of the diagnosis on management

This paper reports a case of a 13 1/2 year old boy with a bipolar affective disorder, who was assumed to be suffering from a post-viral fatigue syndrome. The diagnostic problems in differenting the postviral fatigue syndrome from affective disorders in children/adolescents are discussed. The consequences of misdiagnosis in young people, bearing in mind the developmental tasks that they face, are considered.
