Cognitive behavioral therapy for chronic fatigue syndrome in a general hospital–feasible and effective

Abstract:

Cognitive behavior therapy (CBT) has been shown to be effective in recent randomized controlled trials for chronic fatigue syndrome (CFS). We examined the effectiveness of CBT in a general hospital setting in a retrospective questionnaire follow-up study of 94 patients offered CBT by liaison psychiatry services. The questionnaire response rate was 61%.

Eighteen percent had returned to normal functioning at follow-up. For the group as a whole, there was a significant improvement in the functional and social impairment and the number of frequently experienced symptoms. Those in work or study at follow-up was 53% (29% pretreatment), and 65% of patients mentioned occupational stress as a contributory factor in their illness. There was a significant reduction in the frequency of attendance at primary care in the year after the end of CBT.

We conclude that cognitive behavioral therapy is an acceptable treatment for most patients and can be used in a general hospital outpatient setting by a variety of trained therapists. However, a proportion of patients do not benefit and remain significantly disabled by the condition.

Defensive coping styles in chronic fatigue syndrome

Abstract:

OBJECTIVE: The cognitive-behavioral model of chronic fatigue syndrome (CFS) proposes that rigidly held beliefs act to defend individuals against low self-esteem. This study is the first to investigate the prevalence of a potential mechanism, the Defensive High Anxious coping style, among individuals with CFS.

METHODS: The study comprised 68 participants (24 CFS; 24 healthy volunteers; 20 chronic illness volunteers). Participants completed the Bendig short form of the Taylor Manifest Anxiety Scale (B-MAS) and the Marlowe-Crowne Social Desirability Scale (MC) in order to ascertain the distribution of participants in each group within the four coping styles defined by Weinberger et al. [J. Abnorm. Psychol. 88 (1979) 369].

RESULTS: A greater number of participants in the CFS group (46%) were classified as Defensive High Anxious compared to the two comparison groups [chi(2)(2)=8.84, P=.012].

CONCLUSION: This study provides support for the existence of defensive coping mechanisms as described by the cognitive-behavioral model of CFS. Furthermore, it has been suggested that this particular coping style may impinge directly on physical well being through similar mechanisms as identified in CFS, and further research linking these areas of research is warranted.

Premorbid “overactive” lifestyle in chronic fatigue syndrome and fibromyalgia. An etiological factor or proof of good citizenship?

Abstract:

OBJECTIVE: In a former study, we have shown that patients suffering from chronic fatigue syndrome (CFS) or chronic pain, when questioned about their premorbid lifestyle, reported a high level of “action-proneness” as compared to control groups. The aim of the present study was to control for the patients’ possible idealisation of their previous attitude towards action.

METHODS: A validated Dutch self-report questionnaire measuring “action-proneness” (the HAB) was completed by 62 randomly selected tertiary care CFS and fibromyalgia (FM) patients, as well as by their significant others (SOs).

RESULTS: HAB scores of the patients and those of the SOs were very similar and significantly higher than the norm values. Whether or not the SO showed sympathy for the patient’s illness did not influence the results to a great extent. SOs with a negative attitude towards the illness even characterized the patients as more “action-prone.”

CONCLUSIONS: These results provide further support for the hypothesis that a high level of “action-proneness” may play a predisposing, initiating and/or perpetuating role in CFS and FM.

Chronic fatigue syndrome

Comment in: Chronic fatigue syndrome. [Br J Gen Pract. 2001]

Comment on: Frequency of attendance in general practice and symptoms before development of chronic fatigue syndrome: a case-control study. [Br J Gen Pract. 2001]

 

The study of Hamilton et al in the July issue of the BJGP, 1 claims that a higher consultation rate in people with chronic fatigue syndrome (CFS) before they develop the diagnosis supports the hypothesis that behavioural factors have a role in its aetiology. A similar case-control study of mothers and fathers of Down’s syndrome children showed that both mothers and fathers had significantly more recorded illnesses before the birth of the child and that the mothers had significantly more psychosis, neurosis or self-poisoning.2

The problem with such findings is deciding what they mean. No-one would suggest that Down’s syndrome is caused by ‘behavioural factors,’ so why should anyone believe that of CFS? There is no more evidence that increased frequency of attendance before diagnosis points to behavioural factors in CFS than that it points to non-dysjunction in the germ cells of mothers of Down’s syndrome children.

A comparison of individual and family psychology of adolescents with chronic fatigue syndrome, rheumatoid arthritis, and mood disorders

Abstract:

Chronic fatigue syndrome (CFS) is a controversial diagnosis with unknown cause. Adult studies indicate high rates of psychosocial dysfunction and psychiatric comorbidity. The authors compared three groups of pediatric patients selected by diagnosis-(1l) CFS (n = 15), (2) juvenile rheumatoid arthritis (n = 15), and (3) mood disorders (n = 15)-across many psychological measures.

CFS subjects had dramatic elevation of the Somatic Complaints subscale (mean T score = 75), whereas the mood disorders group had higher externalizing scores (mean T score = 68) on the Child Behavior Checklist. The CFS subjects missed significantly more school compared with the two control groups. After the onset of CFS, 13 of 15 of the CFS patients required significant educational accommodation. Only 4 of the 15 CFS patients had an Axis I psychiatric diagnosis, as determined by the Computerized Diagnostic Interview for Children.

Despite a low rate of psychiatric diagnosis in the CFS sample, these data attest to their psychosocial and school dysfunction.

The Family Response Questionnaire: a new scale to assess the responses of family members to people with chronic fatigue syndrome

Abstract:

OBJECTIVE: Family responses to patients with chronic fatigue syndrome (CFS) may influence the course of the disorder and family members themselves are likely to be adversely affected. However, the beliefs and responses of relatives of CFS patients have been under-researched. The aim of this study was to produce an easy-to-administer questionnaire to assess the responses of family members to people with CFS.

METHODS: Seventy-eight people, all close relatives of (physician-diagnosed) CFS sufferers, completed the first version of the Family Response Questionnaire (FRQ).

RESULTS: Examination of the correlation matrix and a cluster analysis of the items support four scales rather than the original five. The four response scales were labelled: sympathetic-empathic, active engagement, rejecting-hostile, and concern with self. Measures of test-retest and internal reliability were high. Participants found the items both comprehensible and relevant to their experiences of living with people with CFS.

CONCLUSION: The new version of the FRQ will be useful in further examination of the responses of CFS on individuals and their families.

Frequency of attendance in general practice and symptoms before development of chronic fatigue syndrome: a case-control study

Abstract:

BACKGROUND: Chronic fatigue syndrome (CFS) research has concentrated on infective, immunological, and psychological causes. Illness behaviour has received less attention, with most research studying CFS patients after diagnosis. Our previous study on the records of an insurance company showed a highly significant increase in illness reporting before development of CFS.

AIM: To investigate the number and type of general practitioner (GP) consultations by patients with CFS for 15 years before they develop their condition.

DESIGN OF STUDY: Case-control study in 11 general practices in Devon.

SETTING: Forty-nine patients with CFS (satisfying the Centers for Disease Control criteria), 49 age, sex, and general practice matched controls, and 37 patients with multiple sclerosis (MS) were identified from the general practices’ computerised databases.

METHOD: The number of general practice consultations and symptoms recorded in three five-year periods (quinquennia) were counted before development of the patients’ condition.

RESULTS: The median number of consultations was significantly higher for CFS patients than that of matched controls in each of the quinquennia: ratios for first quinquennium = 1.88, P = 0.01; second quinquennium = 1.70, P = 0.005; last quinquennium = 2.25, P < 0.001. More CFS patients than controls attended for 13 of the 18 symptoms studied. Significant increases were found for upper respiratory tract infection (P < 0.001), lethargy (P < 0.001), and vertigo (P = 0.02). Similar results were found for CFS patients when compared with MS.

CONCLUSIONS: CFS patients consulted their GP more frequently in the 15 years before development of their condition, for a wide variety of complaints. Several possibilities may explain these findings. The results support the hypothesis that behavioural factors have a role in the aetiology of CFS.

Chronic fatigue in general practice

Comment on: Chronic fatigue in general practice: is counselling as good as cognitive behaviour therapy? A UK randomised trial. [Br J Gen Pract. 2001]

 

Ridsdale and colleagues are to be congratulated on performing a randomised controlled trial of different treatments for chronic fatigue. However, their data do not substantiate their conclusions.

The trial was set up to demonstrate that cognitive behavioural therapy was better than counselling for patients seen in general practice with fatigue symptoms. No difference in the main outcome measures was found between the intervention and control groups. This has been interpreted as showing that the two treatments are equivalent. The sample size required for, and analysis of, equivalence studies are different than those required for trials designed to show differences,2 not least the requirement that equivalence be defined before the trial starts. This trial was not designed to show equivalence. Thus, although the results for the main outcome measures are similar they should not be reported as being equivalent. Without a definition of equivalence, calculating the study’s power to show equivalence is not possible. Also, part of the conclusions depend on a sub-group analysis which, while acknowledged as being underpowered, is given more weight than is justified. If equivalence is defined as six points on the fatigue score then, in this subgroup, the trial only has a power of 36% to show equivalence based on a 95% confidence interval. With a more conservative definition of equivalence even the main study lacks power.

Cognitive behaviour therapy and chronic fatigue syndrome

Comment on: Chronic fatigue in general practice: is counselling as good as cognitive behaviour therapy? A UK randomised trial. [Br J Gen Pract. 2001]

 

Ridsdale and colleagues state that there is evidence that cognitive behaviour therapy (CBT) is effective for patients with chronic fatigue syndrome (CFS), but fail to point out that such evidence derives only from studies performed in the United Kingdom, where CFS is diagnosed on the basis of the Oxford criteria. There is no evidence that CBT is beneficial to patients fulfilling the Australian criteria for CFS or the American ones, namely, the original criteria of the Centers for Disease Control.

Chronic fatigue: symptom and syndrome

Abstract:

Chronic fatigue is common, is difficult to measure, can be associated with considerable morbidity, and is rarely a subject of controversy. The chronic fatigue syndrome also presents problems in definition and measurement, is associated with even more morbidity than chronic fatigue itself, and is often controversial. Particularly unclear is the way in which chronic fatigue and the chronic fatigue syndrome relate to each other: Is one the severe form of the other, or are they qualitatively and quantitatively different? We know that many things can cause chronic fatigue, and this is probably true for the chronic fatigue syndrome, too. We can anticipate that discrete causes of the chronic fatigue syndrome will be found in the future, even if these causes are unlikely to fall neatly along the physical-psychological divide that some expect. The causes of chronic fatigue are undoubtedly many, both in a population and in any individual person, even when a discrete cause, such as depression or cancer, is identified. Social, behavioral, and psychological variables are important in both chronic fatigue and the chronic fatigue syndrome. Interventions that address these general variables can be successful, and currently they are often more successful than interventions directed at specific causes.
