A rating scale for fibromyalgia and chronic fatigue syndrome (the FibroFatigue scale)

Abstract:

OBJECTIVE: To construct an observer’s rating scale sensitive to change for measuring severity and treatment outcome in fibromyalgia (FM) and chronic fatigue syndrome (CFS) patients.

METHODS: A selection of items from the Comprehensive Psychopathological Rating Scale (CPRS) were repeatedly rated and used as outcome measure of a 24-week treatment study. In the study 100 women, fulfilling the criteria for both FM and CFS, received intermittent injections of a staphylococcus toxoid or placebo. Nine CPRS-items with high baseline incidence (cutoff 70%) were extracted and validated against global ratings and the Fibromyalgia Impact Questionnaire (FIQ). The fibromyalgia and chronic fatigue syndrome rating scale (the FibroFatigue scale) was thereafter formed based upon the extracted items and three supplemented ones. The interrater reliability was tested in 27 consecutive patients of both sexes.

RESULTS: The FibroFatigue scale is an observer’s rating scale with 12 items measuring pain, muscular tension, fatigue, concentration difficulties, failing memory, irritability, sadness, sleep disturbances, and autonomic disturbances (items derived from the CPRS) and irritable bowel, headache, and subjective experience of infection (new items). There was a statistically significant correlation between the CPRS-extracted items and global ratings as well as with the FIQ. The interrater reliability of the new scale was excellent (correlation coefficient.98), irrespective of the patients’ gender.

CONCLUSION: The FibroFatigue scale seems to be a reliable and valid measuring instrument with capacity to monitor symptom severity and change during treatment of FM/CFS patients.

The role of fear of physical movement and activity in chronic fatigue syndrome

Abstract:

OBJECTIVE: To examine beliefs in relation to avoidance of activity in chronic fatigue syndrome (CFS) patients.

METHODS: The first phase consisted of modifying an existing chronic pain measure of kinesiophobia-fear of physical movement and activity-and validating it on the CFS population [Tampa Scale of Kinesiophobia-Fatigue (TSK-F); n=129; test-retest: r=.89, P<.001; alpha=.68]. Subscales of Illness Beliefs (alpha=.78) and Beliefs about Activity (alpha=.70) were identified. The second phase consisted of evaluating whether behavioural persistence was predicted by the TSK-F (n=33). Participants were asked to ride an exercise bike for as long as they felt able.

RESULTS: Analyses indicated that behavioural persistence did not correlate with maximal heart rate or resting heart rate, level of tiredness, symptom severity, illness identity or emotional distress. However, the TSK-F did correlate highly with distance travelled and added a significant 15% of the variance in distance after adjustments for gender and physical functioning (PF). The TSK-F Beliefs about Activity subscale appears to be the predictive factor, explaining 12% of the variance in excise performance or rather 12% of the avoidance of exercise.

CONCLUSION: Beliefs about Activity appear to be an important variable in predicting behaviour and avoidance of exercise. As avoidance has been suggested as a key to the maintenance of symptoms, disability and distress in CFS patients, this research has important theoretical, clinical and research implications.

Cognitive functioning in chronic fatigue syndrome and the role of depression, anxiety, and fatigue

Abstract:

OBJECTIVE: This study was designed to investigate the role of depression, anxiety, and fatigue in Chronic Fatigue Syndrome (CFS) sufferers’ objective and subjective cognitive performance.

METHODS: Twenty-three CFS sufferers and 23 healthy control participants were compared on objective and subjective assessments of cognitive performance. Depression, anxiety, and fatigue were also evaluated.

RESULTS: CFS sufferers did not demonstrate any impairment in objective cognitive functioning compared to the control group, and objective performance was not related to their higher levels of depression or their level of fatigue. Depression scores only accounted for a small amount of the variance in CFS sufferers’ lower subjective assessment of their cognitive performance compared to control participants. There were no differences between the groups on anxiety scores.

CONCLUSION: The results are discussed in terms of the heterogeneity of the CFS population and the complex interaction of symptomatological factors that characterise CFS.

Illness experience, depression, and anxiety in chronic fatigue syndrome

Abstract:

OBJECTIVE: Given the high rate of psychiatric comorbidity with chronic fatigue syndrome (CFS), we considered two possible correlates of anxiety and depression: lack of illness legitimization and beliefs about limiting physical activity.

METHOD: A total of 105 people diagnosed with CFS reported on their experiences with medical professionals and their beliefs about recovery and completed the depression and anxiety subscales of the Brief Symptom Inventory.

RESULTS: Those who said that their physician did not legitimize their illness (36%) had higher depression and anxiety scores (P’s<.05) than their counterparts. Those who believed that limiting their physical exertion was the path to recovery (55%) had lower depression and anxiety scores (P’s<.01) than their counterparts.

CONCLUSION: Lack of illness legitimization ranked high as a source of dissatisfaction for CFS patients, and it may aggravate psychiatric morbidity. Many CFS patients believed that staying within what they felt to be their physical limits would improve their condition. This belief, and possibly an accompanying sense of control over their symptoms, may alleviate psychiatric morbidity.

Fatigue after breast cancer and in chronic fatigue syndrome: similarities and differences

Abstract:

OBJECTIVE: Fatigue is investigated in 57 severely fatigued disease-free breast cancer patients and in 57 gender- and age-matched patients with chronic fatigue syndrome (CFS) using multidimensional and multimethod assessment. A comparison between these groups of patients is important to determine whether a cognitive behavioural intervention to reduce fatigue in CFS patients would be appropriate as well for severely fatigued disease-free breast cancer patients.

METHODS: Measurement included computerised questionnaires and a standardised neuropsychological test. Furthermore, patients filled out a daily Self-Observation List (SOL) and wore an actometer during a period of 12 days.

RESULTS: In comparison to severely fatigued disease-free breast cancer patients, CFS patients score more problematic with regard to the level of fatigue, functional impairment, physical activity, pain and self-efficacy. However, a subgroup of severely fatigued disease-free breast cancer patients reports the same amount of problems as CFS patients with regard to psychological well-being, sleep and concentration. Finally, CFS patients and severely fatigued breast cancer patients score equal on measures of social support.

CONCLUSION: There seem to be some similarities but also many differences between severely fatigued breast cancer survivors and females with CFS. Therefore, cognitive behaviour therapy (CBT) to reduce fatigue after treatment for cancer should also differ in certain aspects from cognitive behaviour therapy as it has been developed for patients with CFS.

Perception of cognitive performance in patients with chronic fatigue syndrome

Abstract:

This study examined discrepancies between perceived and actual performance by patients with chronic fatigue syndrome (CFS) confronted with a challenging cognitive task. Before and after completing a modified version of the Stroop task, 40 patients and 40 healthy control participants estimated their own performance and the performance that would normally be achieved by someone of equal age and education level. After correcting for differences between the groups in depression, we found no differences in actual performance on the Stroop. However, patients with CFS consistently underestimated their performance relative to normal performance. This difference was observed for both depressed and nondepressed subgroups of patients, persisted after adjusting the results for depression, and correlated with patients’ ratings of the mental effort and fatigue evoked by the task. The results are discussed in light of cognitive models of CFS that suggest the setting of impossibly high standards of personal performance may contribute to the dynamism of this disease.

Chronic fatigue syndrome: successful outcome of an intensive inpatient programme

Abstract:

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.

Chronic fatigue syndrome in the psychiatric practice

Abstract:

BACKGROUND: Chronic fatigue syndrome (CFS) is a complex syndrome with a psychiatric comorbidity of 70-80%. A psychiatric interview is necessary in order to exclude psychiatric illness and to identify psychiatric comorbidity. Studies have demonstrated that in general medical practice and in the non-psychiatric specialist practice, physicians tend to underdiagnose psychopathology in patients with CFS. There are many questions unanswered about the treatment of CFS Aim: Typical issues for the psychiatric practice are reviewed: psychiatric comorbidity, dysregulation of the PHA-axis and the treatment of CFS.

CONCLUSIONS: Depression, somatization, sleeping disorders and anxiety disorders are the most important psychopathological symptoms found in CFS patients. CFS should not be regarded as a masked (somatoform) depression. Although the results from neuroendocrinological studies assessing the hypothalamic-pituitary-adrenal axis (HPA-axis) are inconsistent, they suggest that there is a subgroup of CFS patients suffering from a discrete dysregulation of the HPA-axis resulting in basal hypocortisolaemia. These findings, however, do not reveal a causal relationship. Antidepressants do not seem to have a positive influence on the symptom of fatigue, but appear to be beneficial in alleviating the symptoms of depression and social functioning. Cognitive behaviour therapy and graded exercise show a significant improvement on fatigue and other symptoms and are the only treatments available for CFS patients.

The symptoms and management of myalgic encephalomyelitis

Abstract:

Myalgic encephalomyelitis (ME), which is also known as chronic fatigue syndrome, is a chronic, debilitating illness with varying symptoms and patterns of progression. Research has yet to establish its aetiology and pathogenesis, and there is no cure. A number of management strategies have proved effective, but these should always be tailored to the individual patient. Although no drug treatment has been developed specifically for ME, therapies used to manage the same symptoms in other conditions can provide some relief. Treatment and management should be planned in partnership with the patient.
