A brief mental fatigue questionnaire

Abstract:

A brief mental fatigue questionnaire was administered to normal subjects and muscle-diseased, Chronic Fatigue Syndrome (CFS), recovered CFS and depressed patients. The questionnaire was found to have excellent internal consistency and discriminated effectively between CFS and depressed patients on the one hand and recovered CFS, normal and muscle-diseased patients on the other. However, the scale failed to discriminate between CFS and depressed subjects, who were found to experience qualitatively and quantitatively similar mental fatigue symptoms.

General practitioners acceptance of the validity of chronic fatigue syndrome as a diagnosis

Abstract:

AIM: To identify whether general practitioners accept the validity of a diagnosis of chronic fatigue syndrome (CFS).

METHOD: An anonymous questionnaire was sent out to 98 general practitioners in Otago.

RESULTS: The clinical validity of chronic fatigue syndrome was accepted by 74 (90%); 57 believed they had sufficient knowledge about the condition to make a differential diagnosis; 72 indicated they had had patients with chronic fatigue syndrome in the past; 62 currently had patients; there is a minimum prevalence rate of 167/100,000 in the general practice population; 83 replies were received.

CONCLUSION: The 90% acceptance rate of chronic fatigue syndrome as a clinically valid diagnosis suggests that amongst the Otago general practitioners the controversy had receded. The low numbers suggest that they are on the conservative end of the diagnostic spectrum.

Fatigue, depression, and social adjustment in chronic fatigue syndrome

Abstract:

The aims of this study were to determine the characteristics and perceived levels of fatigue and the prevalence of depression in children with chronic fatigue syndrome and to assess the effects of illness on schooling and social functioning.

Twelve children with chronic fatigue syndrome were compared with a matched group of children with cystic fibrosis and matched healthy controls. Levels of fatigue (fatigue questionnaire), depression (children’s depression inventory), and social adjustment (semistructured interview with parents) were compared between groups.

Children with chronic fatigue syndrome had significantly higher median scores for physical and mental fatigue and depressive symptomatology than either comparison group and five children scored as depressed on the children’s depression inventory.

Schooling and social functioning were seriously disrupted. Children with chronic fatigue syndrome reported high levels of fatigue affecting both physical and mental functioning, the association with depression found in adult studies was confirmed, and social adjustment was poor.

Taking exception to chronic fatigue syndrome prevalence findings by Price, et al.

Comment on: Estimating the prevalence of chronic fatigue syndrome and associated symptoms in the community. [Public Health Rep. 1992]

 

We would like to address some serious methodological issues in the article, “Estimating the Prevalence of Chronic Fatigue Syndrome and Associated Symptoms in the Community,” by Rumi K. Price, et al., published in the September-October issue of Public Health Reports. We believe that because of the deficiencies in the design of this research, the authors’ conclusions are totally illogical and invalid.

In this article, the authors conclude that Chronic Fatigue Syndrome (CFS), as defined by the Centers for Disease Control (CDC) Diagnostic Criteria, might be “quite rare” in the general population, as only 1 of 13,538 individuals studied was deemed to have CFS. The official CDC Diagnostic Criteria, however, were not utilized to diagnose cases of CFS. Instead, the researchers reviewed interview questionnaire data collected between 1981 and 1984 for a purpose unrelated to diagnosing CFS. In fact, the CDC Diagnostic Criteria were not formulated and published until 1988.

Ocular manifestations of chronic fatigue and immune dysfunction syndrome

Abstract:

Chronic fatigue and immune dysfunction syndrome (CFIDS) is a disease presenting with systemic, sensory, cognitive, and psychological manifestations. Ocular symptomatology is reported in the visual, functional, perceptual, and pathological aspects of the visual system. The purpose of the research was to evaluate ocular symptoms in patients with CFIDS.

One hundred and ninety CFIDS patients [155 females, 35 males; mean age of 41 years (range 15 to 72)] and 198 healthy controls [133 females, 65 males; mean age of 42 years (range 8 to 89)] were surveyed via written questionnaire. Evaluation of data showed statistical significance at levels ranging from 0.0001 to 0.007 for all but one symptom surveyed. It appears that the ocular symptoms of CFIDS are genuine. Further research is needed to determine the etiology and appropriate treatment of this disease.

Chronic fatigue syndrome criteria. A critique of the requirement for multiple physical complaints

Abstract:

OBJECTIVE: The purpose of this study was to test the hypothesis that the patients with chronic fatigue who have the highest number of medically unexplained physical symptoms over their lifetime would also have the highest prevalence of current and lifetime affective and anxiety disorders, lifetime affective symptoms, and the most functional disability. A further goal was to use this information to modify the current case definition to better identify a subgroup of patients with chronic fatigue syndrome who are less likely to have psychiatric illness.

DESIGN: Two hundred eighty-five consecutive patients with chronic fatigue were interviewed with the National Institute of Mental Health Diagnostic Interview Schedule and completed four self-rating questionnaires measuring psychologic distress, functional disability, and the tendency to amplify symptoms. Based on previously published data, patients were divided into four groups with a progressively higher number of lifetime medically unexplained physical symptoms. The prevalence of current and lifetime psychiatric disorders, lifetime psychologic symptoms, and extent of functional impairment was then compared in these four groups of patients.

MAIN RESULTS: The prevalence of current and lifetime psychiatric diagnosis and lifetime depressive symptoms increased linearly with the number of lifetime physical symptoms that the patient experienced. The extent of impairment in activities of daily living and the tendency to amplify symptoms also increased linearly with the number of medically unexplained physical symptoms.

CONCLUSION: The patients with the highest numbers of medically unexplained physical symptoms had extraordinarily high rates of current and lifetime psychiatric disorders. These data suggest that the current case definition for chronic fatigue syndrome inadvertently selects for patients with the highest prevalence of lifetime psychiatric diagnoses. A recommendation based on these results is to modify the case criteria for chronic fatigue syndrome to include patients with fatigue and few physical symptoms and to identify and consider excluding patients with high numbers of physical complaints.

Follow up of patients presenting with fatigue to an infectious diseases clinic

Abstract:

OBJECTIVES: To determine the symptomatic and functional status during follow up of patients referred to hospital with unexplained fatigue and to identify patient variables associated with persistent functional impairment.

DESIGN: Follow up by postal questionnaire six weeks to four years (median 1 year) after initial clinical assessment of patients referred to hospital during 1984-8.

SETTING: Infectious diseases outpatient clinic in a teaching hospital.

PATIENTS: 200 consecutive patients with fatigue of uncertain cause for at least six weeks; 177 fulfilled the inclusion criteria.

MAIN OUTCOME MEASURES: Findings at initial assessment; current symptoms, beliefs about the cause of illness, coping behaviours emotional disorder, social variables including membership of self help organizations, and degrees of recovery and functional impairment from questionnaire responses.

RESULTS: 144 (81%) patients returned completed questionnaires. Initial assessment did not indicate the cause of fatigue, other than preceding infection. The proportion of patients with functional impairment was significantly smaller with longer follow up (33% (11/33) at two to four years, 73% (29/40) at six weeks to six months; chi 2 for trend = 12.5, df = 1; p less than 0.05). Functional impairment was significantly associated with belief in a viral cause of the illness (odds ratio = 3.9; 95% confidence interval 1.5 to 9.9), limiting exercise (3.2; 1.5 to 6.6), avoiding alcohol (4.5; 1.8 to 11.3), changing or leaving employment (3.1; 1.4 to 6.9), belonging to a self help organization (7.8; 2.5 to 23.9), and current emotional disorder (4.4; 2.0 to 9.3).

CONCLUSIONS: Short term prognosis for recovery of function was poor but improved with time. Most patients had made a functional recovery by two years after initial clinic attendance. Impaired functioning was more likely with certain patient characteristics. Prospective studies are required to clarify whether these associations are the consequences of a more disabling illness or indicate factors contributing to impaired function.

Illness perception and symptom components in chronic fatigue syndrome

Abstract:

Two-hundred and eight patients with chronic fatigue syndrome (post-viral fatigue syndrome) completed a questionnaire which dealt both with their illness in general and with the extent to which they experienced specific symptoms. A factor analysis of the symptom data yielded four components: emotional distress; fatigue; somatic symptoms; and cognitive difficulty.

Emotional disturbance is a common feature of the disorder and its role has been widely debated. When the symptom components were considered independently, fatigue, somatic symptoms and cognitive difficulty were associated with questionnaire items relating to general illness severity, but emotional distress was not.

Thus negative emotions did not contribute directly to patients’ perception of illness severity. They were, however, correlated with the other symptom components. It is argued that this correlation reflects a reciprocal influence, with negative emotions exacerbating fatigue and other key symptoms and the debilitating nature of these symptoms enhancing emotional vulnerability.

Biopsychosocial aspects of chronic fatigue syndrome (myalgic encephalomyelitis)

Abstract:

Fifteen patients, with a primary complaint of chronic fatigue, were referred to a physician by their general practitioners. Psychological distress, measured by simple psychiatric rating scales was common, but specific psychiatric diagnoses, derived from a comprehensive diagnostic interview, occurred less frequently.

One questionnaire (Montgomery-Asberg depression rating scale) found emotional distress in 93%, but the diagnostic instrument (Present State Examination) suggested depressive syndromes in only two patients (13%). There were significant occupational difficulties in 87%. No consistently abnormal indices of biochemical or immunological function were found, nor evidence of acute or chronic infection.

Chronic fatigue syndrome (CFS) is associated with physical, psychological and social distress. The illness cannot be defined using just one of these dimensions. Such a unilateral approach has resulted in unnecessary controversy over the nature of the ‘real’ core of CFS. A problem-oriented approach, recognising the multi-factorial and overlapping cause and effect issues in CFS, may be of more benefit to patients.

Tired, weak, or in need of rest: fatigue among general practice attenders

Abstract:

OBJECTIVES: To determine the prevalence and associations of symptoms of fatigue.

DESIGN: Questionnaire survey.

SETTING: London general practice.

PARTICIPANTS: 611 General practice attenders.

MAIN OUTCOME MEASURES: Scores on a fatigue questionnaire and reasons given for fatigue.

RESULTS: 10.2% Of men (17/167) and 10.6% of women (47/444) had substantial fatigue for one month or more. Age, occupation, and marital status exerted minor effects. Subjects attributed fatigue equally to physical and non-physical causes. Physical ill health, including viral infection, was associated with more severe fatigue. Women rather than men blamed family responsibilities for their fatigue. The profile of persistent fatigue did not differ from that of short duration. Only one person met criteria for the chronic fatigue syndrome.

CONCLUSIONS: Fatigue is a common complaint among general practice attenders and can be severe. Patients may attribute this to physical, psychological, and social stress.
