Personality in adolescents with chronic fatigue syndrome

Commentary: Against the widespread use of other types of PD diagnosis - a commentary on the May 2022 debate (should CAMH professionals be diagnosing personality disorder in adolescence?)

Recent debate papers in Child and Adolescent Mental Health (Debate CAMH, May 2022) advocate a more widespread and appropriate use by CAMH clinicians of borderline personality disorder diagnoses. This paper makes the case against the widespread use of other types of PD diagnosis in children and young people. Nevertheless, it would be of interest to establish to what extent adult PDs have their roots in early neurodevelopmental anomalies, and ascertainment of personality traits can help clarify children's response to environmental or traumatic stresses in those presenting with problems such as at the interface between physical and mental health.

Somatising in children and adolescents. 2. Management and outcomes

In this paper I outline the assessment, engagement and management of children and adolescents with somatising conditions. The major diagnostic groups, in rough order of prevalence, are adjustment, dissociative (transient and chronic), somatoform and factitious disorders and chronic fatigue. See Eminson (2001) for more detailed descriptions and subtypes.

Somatising in children and adolescents. 1. Clinical presentations and aetiological factors

Somatising disorders, characterised by complaints of unexplained physical symptoms, are common presentations in children and adolescents, both in primary and secondary care settings. They have significant impact on the children themselves and on health care resources: as in adults, there is a wide range of severity and resulting handicaps.

Important factors to consider when treating children with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME): perspectives of health professionals from specialist services

BACKGROUND

Paediatric Chronic Fatigue Syndrome (CFS)/Myalgic Encephalomyelitis (ME) is relatively common and disabling. Improving treatment requires the development of Patient Reported Outcome Measures (PROMs) that enable clinicians and researchers to collect patient-centred evidence on outcomes. Health professionals are well placed to provide clinical insight into the condition, its treatment and possible outcomes. This study aimed to understand the perspectives of specialist paediatric CFS/ME health professionals and identify outcomes that are clinically important.

METHODS

Focus groups and interviews were held with 15 health professionals involved in the care of children with CFS/ME from the four largest specialist paediatric CFS/ME services in the NHS in England. A range of clinical disciplines were included and experience in paediatric CFS/ME ranged from 2 months to 25 years. Ten participants (67%) were female. Focus groups and interviews were recorded, transcribed verbatim and data were analysed using thematic analysis.

RESULTS

All health professionals identified the impact of CFS/ME across multiple aspects of health. Health professionals described four areas used to assess the severity of the illness and outcome in children: 1) symptoms; 2) physical function; 3) participation (school, activities and social life); and 4) emotional wellbeing. They also described the complexity of the condition, contextual factors and considerations for treatment to help children to cope with the condition.

CONCLUSIONS

Clinically important outcomes in paediatric CFS/ME involve a range of aspects of health. Health professionals consider increases in physical function yet maintaining school functioning and participation more widely as important outcomes from treatment. The results are similar to those described by children in a recent study and will be combined to develop a new child-specific PROM that has strong clinical utility and patient relevance.

What matters to children with CFS/ME? A conceptual model as the first stage in developing a PROM

BACKGROUND

Paediatric chronic fatigue syndrome (CFS)/myalgic encephalomyelitis (ME) is relatively common and disabling. Research is hampered because current patient-reported outcome measures (PROMs) do not capture outcomes that are important to children with CFS/ME.

AIM

The aim of this study was to explore the aspects of life and health outcomes that matter to children with CFS/ME.

METHODS

Twenty-five children with CFS/ME were interviewed (11 males, 14 females; mean age 12.9 years (SD 2.2), range 8-17). Twelve were trial participants interviewed during the trial and 13 were recruited as part of a follow-up qualitative study. Parents were present in 19 interviews with their children. Three mothers participated in a focus group. All the interviews and the focus group were audio-recorded and transcribed. Data were analysed thematically using techniques of constant comparison. NVivo was used to structure and categorise data in a systematic way.

RESULTS

Children identified four key themes (health outcome domains): 'symptoms' that fluctuated, which caused an unpredictable reduction in both 'physical activity' and 'social participation' all of which impacted on 'emotional well-being'. These domains were influenced by both 'management' and 'contextual factors', which could be positive and negative. The relationship between healthcare and school was considered pivotal.

CONCLUSIONS

Children's descriptions helped to inform a conceptual model that is necessary to develop a new paediatric CFS/ME PROM. Doctors need to be aware of how children conceptualise CFS/ME; the relationship between healthcare and school is fundamental to ameliorate the impact of CFS/ME.

Personality dysfunction is the cause of recurrent non-cognitive mental disorder: a testable hypothesis

OBJECTIVE

The objective of this study is to examine the evidence for a new hypothesis explaining the relationship between personality and mental state disorders.

DESIGN

At present, the attribution of personality disorder as a primary diagnosis only applies to patients who are antisocial, and particularly regarded as psychopathic, as in these patients, the mental state disorder that are associated are regarded in many respects as atypical and not representative of other mental disorders. The case is made in this paper that personality dysfunction lies behind the persistence of all non-cognitive mental disorders and that our failure to recognise this follows from our collective refusal to assess personality status early in life.

METHOD

Narrative review of relevant literature, which is limited as personality status is not often assessed early in life.

RESULTS

Support is adduced that personality dysfunction lies behind the persistence of all non-cognitive mental disorders (i.e. those that are not specifically neurodevelopmental and linked to cognitive impairment). The potential importance of this hypothesis is presented with regard to treatment and management strategy, emphasising that without specific intervention for personality dysfunction, many patients are destined for persistent morbidity.

Cortisol output in adolescents with chronic fatigue syndrome: pilot study on the comparison with healthy adolescents and change after cognitive behavioural guided self-help treatment

OBJECTIVE

This study examined cortisol in adolescents with chronic fatigue syndrome (CFS) compared to healthy adolescents and changes in cortisol after cognitive behavioural guided self-help treatment. Exploratory analyses investigated the association between cortisol output and psychological variables.

METHODS

Salivary cortisol was measured upon awakening, at 15, 30, 45 and 60 min afterwards and at 12 noon, 4:00 p.m. and 8:00 p.m., in adolescents with CFS and healthy controls (HC). Groups were matched for age, gender, menarche status, menstrual cycle and awakening time. Twenty-four adolescents with CFS provided saliva samples six months after treatment. The main outcome measure was total salivary output over the day, calculated by area under the curve (AUC). The salivary awakening response was also assessed.

RESULTS

Cortisol output over the day was significantly lower in the CFS group (n=46) than in healthy controls (n=33). Within the CFS group, lower daily cortisol output was associated with higher self-reported perfectionist striving and prosocial behaviour. There were no significant group differences in the awakening response (n=47 CFS versus n=34 HC). After treatment, adolescents with CFS (n=21) showed a significant increase in daily cortisol output, up to normal levels.

CONCLUSION

The reduced daily cortisol output in adolescents with CFS is in line with adult findings. Associations between reduced cortisol output and two psychological variables-perfectionism and prosocial behaviour-are consistent with cognitive behavioural models of chronic fatigue syndrome. The mild hypocortisolism is reversible; cortisol output had returned to healthy adolescent levels by six months after cognitive behavioural guided self-help treatment.

Why do young people with CFS/ME feel anxious? A qualitative study

Young people with chronic fatigue syndrome or myalagic encephalopathy (CFS/ME) (CFS/ME) experience higher levels of psychological distress than healthy controls and young people with other chronic illnesses, and it was recently demonstrated that 38% of this population scored above the clinical cut-off on the Spence Child Anxiety Scale. Subscales of social and separation anxiety were consistently high across gender and age groups. In this study, we used qualitative methods to help us understand more about these two types of anxiety in young people with CFS/ME. Eleven young people (age 12-18) were interviewed. Interviews were self-directed by the participants and were wide ranging. The transcripts were analysed using interpretative phenomenological analysis. Five superordinate themes were identified: social loss and adjustment; introduction of uncertainty and unpredictability; the vulnerable self; individual differences; and contributions towards recovery. Many themes were identical to those described in young people coping with other chronic illnesses in adolescence. In addition, young people with CFS/ME describe experiences associated with the perceived illegitimacy of this condition, namely: feeling unable to explain their illness; bullying from peers; disbelief; and distrust from adults around them. This becomes an additional challenge for these young people. Clinicians need to be aware of these problems, and offer appropriate support.

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.

Effort-reward imbalance for learning is associated with fatigue in school children

We examined relationships among fatigue, sleep quality, and effort-reward imbalance for learning in school children. We developed an effort-reward for learning scale in school students and examined its reliability and validity. Self-administered surveys, including the effort reward for leaning scale and fatigue scale, were completed by 1,023 elementary school students (grades 4-6) and 1,361 junior high school students (grades 7-9) at the end of 2006. Effort-reward imbalance for learning was associated with a high incidence of fatigue and sleep problems in elementary and junior high school students of both genders. A good relationship with family was associated with a low fatigue score in junior high school boys, and a good relationship with friends was associated with a low fatigue score in junior high school girls by multiple regression analysis. Fatigue score was associated with effort-reward imbalance and fatigue and quality of sleep in schoolchildren. Fatigue may lead to a decline in school performance, negative health outcomes, or refusal to attend school. These results suggest that it is desirable to consider social support, quality of sleep, and effort-reward imbalance when managing fatigue in school children.

Critical developments in the assessment of personality disorder

BACKGROUND

The assessment of personality disorder is currently inaccurate, largely unreliable, frequently wrong and in need of improvement.

AIMS

To describe the errors inherent in the current systems and to indicate recent ways of improving personality assessment.

METHOD

Historical review, description of recent developments, including temporal stability, and of studies using document-derived assessment.

RESULTS

Studies of interrater agreement and accuracy of diagnosis in complex patients with independently established personality status using document-derived assessment (PAS-DOC) with a four personality cluster classification, showed very good agreement between raters for the flamboyant cluster B group of personalities, generally good agreement for the anxious/dependent cluster C group and inhibited (obsessional) cluster D group, but only fair agreement for the withdrawn cluster A group. Overall diagnostic accuracy was 71%.

CONCLUSIONS

Personality function or diathesis, a fluctuating state, is a better description than personality disorder. The best form of assessment is one that uses longitudinal repeated measures using a four-dimensional system.

Personality and chronic fatigue syndrome: Methodological and conceptual issues

Among clinical psychologists, consulting physicians, scientific researchers and society in general an image has emerged of patients with chronic fatigue syndrome (CFS) as perfectionist, conscientious, hardworking, somewhat neurotic and introverted individuals with high personal standards, a great desire to be socially accepted and with a history of continuously pushing themselves past their limits. The aim of this article is to (a) give a concise review of the main recent studies on personality and CFS, (b) address the major methodological problems in the study of personality in CFS and (c) discuss some of the conceptual assumptions that seem to limit the research on personality and CFS. The results of the reviewed studies range from no evidence of major differences between the personalities of patients with CFS and controls, to evidence of severe psychopathology and personality disorder in patients with CFS. Although personality seems to play a role in CFS, it is difficult to draw general conclusions on the relation between personality and CFS. It is argued that this is partially due to the diversity and heterogeneity in study methods, patient populations, control groups and CFS case definitions. Personality should be regarded as an important factor to be studied in CFS. However, additional studies are needed, not focusing exclusively on personality disorder, or personality considered on a general trait level. In recent developments in personality research, the continually evolving life narrative that makes sense of, and gives direction to, an individual's life is also regarded as an important aspect of personality. New insights into personality and CFS might be gained by systematically studying the self-narratives of patients with the syndrome.

Medically unexplained symptoms in children and adolescents

A review is presented of the range of medically unexplained symptoms (MUS) in children and adolescents, with an account of the main presentations that are recognised in clinical settings in paediatric and children's mental health services. A summary of both epidemiological and clinical studies of symptoms and their associations is given, followed by a brief overview of aetiological theories and of management interventions.

Chronic fatigue syndrome of childhood. Comparative study with emotional disorders

OBJECTIVE

To examine clinical specificity in chronic fatigue syndrome (CFS) of childhood, by comparing clinical features in childhood CFS and in emotional disorders (ED). METHOD SAMPLE: 28 children with CFS; 27 with ED.

MEASURES

History of disorder; K-SADS psychiatric interviews; self-esteem and physical symptoms questionnaires; premorbid history, behavioural and personality assessments.

RESULTS

There were high levels of comorbid emotional disorders in children with CFS, and the two groups were comparable on self-esteem, but CFS children endorsed more fatigue and other somatic symptoms. The two groups were comparable on age at illness onset, but parents of children with CSF reported more biological illness precipitants, more pre-morbid recurrent medical problems and infections. The CFS group had fewer pre-morbid psychological problems and less psychiatric comorbidity than the ED group.

CONCLUSION

There is considerable clinical overlap between CFS and ED of childhood, but there are also differences in clinical presentation between these disorders.

Suicide among adolescents. A psychological autopsy study of psychiatric, psychosocial and personality-related risk factors

BACKGROUND

The suicide rate among young males in Belgium has doubled over the last decade. As more knowledge about risk factors is required to develop national prevention strategies, we investigated adolescent suicides using the psychological autopsy method.

METHODS

A total of 32 informants were interviewed regarding 19 suicide cases (aged 15-19). A semi-structured interview schedule, constructed by Houston et al. (J Affect Disord 63:159-170, 2001), was used.

RESULTS

All adolescents were suffering from one or more mental disorder(s) at the time of their death, and almost half of them were diagnosed with personality disorders. Adjustment disorders were diagnosed in one fifth of the sample, which appears to be relevant in view of the multiple life events and other psychosocial problems which adolescents were facing shortly before death. This suggests that difficulties in coping with stressful psychosocial problems are important in the course of the suicidal process. Only a small minority was receiving treatment for their disorders.

CONCLUSIONS

Mental disorders, commonly untreated and combined with personality disorders and psychosocial problems, are frequently found in young suicide victims. This study suggests that education in the diagnosis and treatment of depression, adjustment disorders and suicide is important in the prevention of suicide.

Practitioner review: chronic fatigue syndrome in childhood

BACKGROUND

Chronic fatigue syndrome (CFS) is being increasingly recognized in children and adolescents. Yet comparatively little attention has been given in the literature to management.

METHODS

Description of the main features of the disorder, precipitating and maintaining factors and diagnostic assessment. Outline of different views on the nature and treatment of CFS in childhood. Description of a rehabilitation program based on cognitive behavior therapy and graded activity.

RESULTS

Using adult research criteria, CFS can be diagnosed in children and adolescents. In its severe form it is often triggered by infectious illness episodes. It is commonly associated with mood disorders in the child and with mental distress and high levels of emotional involvement in parents. A number of patient support groups hold the view that CFS is a medical disorder, contest a psychiatric contribution and advocate 'pacing' as an approach to rehabilitation which includes avoiding activities. To date there is no empirical evidence for the efficacy of this approach. Research in adults, open and clinical reports in children support the use of graded activity and family cognitive behavior therapy. The main aim is to enable children, with the help of their family, to carry out their own rehabilitation with some support and guidance from a health professional. Engaging the child and family in treatment and forming a therapeutic alliance is a continual process and a crucial aspect of management, as many families view the condition as a medical disorder and are initially ambivalent towards this approach.

CONCLUSIONS

There is controversy about the nature and management of CFS in childhood but a rehabilitation program based on family cognitive behavior therapy can be implemented and seems to hold most promise in the management of children with CFS. Family engagement is a crucial aspect of management.

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.

The Interface Between Physical and Mental Health Problems and Medical Help Seeking in Children and Adolescents: A Research Perspective

This paper addresses child and adolescent psychopathology as it presents to general practitioners and paediatricians, and explores psychosocial aspects of unexplained medical symptoms in children and adolescents. High rates of psychopathology have been identified amongst children and adolescents attending general practice and paediatric services, most of it ''hidden'' at presentation and emotional in nature. It is often linked to poor physical well being and to maternal stress focused on the child. It may be of special relevance to medical help seeking in socio-economically advantaged areas. Co-morbid psychopathology, mainly emotional disorders, is common amongst children with unexplained medical symptoms. However, there are specific psychosocial aspects that differentiate these children from those with emotional disorders. They involve disease beliefs, illness behaviour and predicament. The latter may be characterised by special reactivity to stress in children with personality vulnerability, in a context of parents with high levels of mental distress, unexplained medical symptoms and emotional over-involvement with the child. There is comparatively little interface work between CAMHS and primary health care. An important research priority would seem to lie in the development of interventions that can be adapted for use by primary care staff. Similarly, there are few dedicated CAMHS paediatric liaison teams. Their more extensive development should help attend in a more informed and focused way than at present to children and adolescents suffering from unexplained physical symptoms and disorders. Further research is needed into vulnerability mechanisms and maintaining factors, health beliefs, treatment engagement and interventions.

Chronic Fatigue: A Survey, Outcome Study and Proposals

BACKGROUND

  Sample sizes in studies of childhood chronic fatigue remain small and there is a need to integrate research findings and establish common criteria.

METHOD

  This is a detailed report of 20 children with medically unexplained fatigue, referred to as Chronic Fatigue Syndrome (CFS). It includes an uncontrolled outcome study of treatment based on a pragmatic cognitive-behavioural model adapted for children at Great Ormond Street Hospital for Children.

RESULTS

  The data revealed psychological distress at 30 times the prevalence found in the normal child population, with specific high-ranking symptoms, including headache, social withdrawal and decreased appetite. Onset tended to occur at 11 years of age with some earlier problems at school age, suggesting it might be possible to identify those most at risk. Follow-up demonstrated improvement in 87% of the sample (parental report), a significant increase in school attendance and a significant decrease in symptom severity. Factors associated with good outcome were short duration of fatigue (less than a year) and behaviours that tended to combat the cycle of avoidance, such as carefully planned home-tuition.

CONCLUSIONS

  Recording a comprehensive range of symptoms and factors facilitates comparisons within and between child studies. It is proposed that symptom severity is a particularly relevant measure for Chronic Fatigue Syndrome which is characterised by persisting symptoms.

Psychiatric management of severe somatoform disorders in childhood and adolescence

BACKGROUND

Unexplained medical symptoms are common in children. They constitute the main feature of somatoform disorders of childhood (i.e. pain disorders, conversion disorder and chronic fatigue syndrome or neurasthenia).

OBJECTIVE

To describe assessment and treatment strategies for severe somatoform disorders of childhood.

METHODS

Review of recommendations for clinical practice and clinical trials.

RESULTS

A number of specific techniques have been described. Clinical accounts indicate that many children benefit and can recover. There is some empirical evidence supporting the beneficial effects of techniques such as family cognitive-behavioural therapy and relaxation technique for the less severe disorders.

CONCLUSIONS

Existing helpful clinical guidelines require empiric validation.

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.
