The description of psychological aspects of fibromyalgia are similar to those of other patients with chronic pain. Three groups, a chronic pain group (n = 99), a nonchronic pain group (n = 34) and a fibromyalgia group (n = 36) were compared, using a standardized interview and psychological questionnaires (SCL-90R, IBQ and CIPI). It appeared that the chronic pain group and the nonchronic pain group could be easily distinguished from each other with these variables. The scores of the fibromyalgia group and the chronic pain group were very similar. This leads to the conclusion that many psychological aspects of fibromyalgia can be considered as psychological aspects of chronic pain.

Fibrositis (fibromyalgia) patients were compared with normal controls in terms of electrophysiology (EEG), self-report indicants of awakening, quality of sleep, behaviourally signalled awakenings, and Symptom Check List 90R (SCL-90R) scores. The results differentiated fibrositis patients from normal controls in terms of SCL-90R scores, with fibrositis patients showing significantly more psychopathology. Fibrositis patients had more alpha EEG sleep and less REM and Stage 1 sleep. They were better able to recall their behaviourally signalled awakenings the following morning and reported qualitatively less satisfying sleep than the normal controls. The alpha EEG sleep anomaly may reflect a vigilant arousal state during nocturnal sleep and result in the daytime experience of unrefreshing sleep, psychologic distress, that re-enforces the perpetuation of the sleep-related symptoms.

Twenty-two patients with fibrositis and 22 control patients selected from a general medical outpatient population were given 3 standardized psychological questionnaires: the Beck Depression Inventory, the Spielberger State and Trait Anxiety Inventory, and the SCL-90-R. There were no statistically significant differences between fibrositis patients and control patients on any of these tests, a finding at variance with a commonly held belief that patients with fibrositis have an underlying psychological disorder. While psychological factors may be important in some patients with fibrositis, these results indicate that the presence of a psychopathologic condition is not mandatory for the persistence of fibrositis.

Fibromyalgia is a chronic illness characterized by widespread pain, fatigue, sleep disturbance, and resistance to treatment. The purpose of this study was to evaluate the effectiveness of a meditation-based stress reduction program on fibromyalgia. Seventy-seven patients meeting the 1990 criteria of the American College of Rheumatology for fibromyalgia took part in a 10-week group outpatient program. Therapists followed a carefully defined treatment approach and met weekly to further promote uniformity. Patients were evaluated before and after the program. Initial evaluation included a psychiatric structured clinical interview (SCID). Outcome measures included visual analog scales to measure global well-being, pain, sleep, fatigue, and feeling refreshed in the morning. Patients also completed a medical symptom checklist, SCL-90-R, Coping Strategies Questionnaire, Fibromyalgia Impact Questionnaire, and the Fibromyalgia Attitude Index. Although the mean scores of all the patients completing the program showed improvement, 51% showed moderate to marked improvement and only they were counted as "responders." These preliminary findings suggest that a meditation-based stress reduction program is effective for patients with fibromyalgia.

The purpose of this investigation was to compare self-reported sleep quality and psychological distress, as well as somnographic sleep and physiological stress arousal, in women recruited from the community with self-reported medically diagnosed fibromyalgia (FM) to women without somatic symptoms. Eleven midlife women with FM, when compared to 11 asymptomatic women, reported poorer sleep quality and higher SCL-90 psychological distress scores. Women with FM also had more early night transitional sleep (stage 1) (p < 0.01), more sleep stage changes (p < 0.03) and a higher sleep fragmentation index (p < 0.03), but did not differ in alpha-EEG-NREM activity (a marker believed to accompany FM). No physiological stress arousal differences were evident. Less stable sleep in the early night supports a postulate that nighttime hormone (e.g., growth hormone) disturbance is an etiologic factor but, contrary to several literature assertions, alpha-EEG-NREM activity sleep does not appear to be a specific marker of FM. Further study of mechanisms is needed to guide treatment options.

The objective of the study was to evaluate the physical capacity and effort in patients with fibromyalgia. Muscle strength and the coefficient of variation of the strength measurements of 181 female fibromyalgia patients and 126 healthy females were compared. These measurements and ergometer exercise capacity, work status and psychometric scoring (SCL-90-R) were correlated. The fibromyalgia patients exhibited significant reduction in voluntary muscle strength of the knee and elbow, flexors and extensors in the order of 20-30%. However, the coefficient of variation was higher among patients, thus indicating lower effort. The physical performance during an ergometer test corresponded to a maximal oxygen consumption of 21 ml/kg-1 x min-1. The maximal increase in heart rate was only 63% (44-90%) of the predicted increase. Degree of effort or physical capacity did not correlate to psychometric scores. Work status was related to psychometric scoring, but not to physical capacity or effort. In conclusion, we found a low degree of effort but near normal physical capacity in the fibromyalgia patients.

Based on a possible involvement of serotonergic dysfunction in the pathophysiology of fibromyalgia (FM) and on preliminary reports of a possible genetically driven vulnerability for this disorder we investigated the silent T102C polymorphism of the 5-HT2A-receptor gene in 168 FM patients and 115 healthy controls. Our results showed a significantly different genotype distribution in FM patients with a decrease in T/T and an increase in both T/C and C/C genotypes as compared to the control population (Fisher's Exact test, two-sided, P = 0.008). However, the increase in allele-C102 frequency felt short of significance (P = 0.07). Correlation of genotypes to clinical parameters revealed no influences on age of onset, duration of disease or psychopathological symptoms, measured with the Beck Depression Inventory and the symptom checklist SCL-90-R. In contrast to that the pain score, being a self reported information on pain severity, was significantly higher in patients of the T/T genotype (Mann-Whitney U test, P = 0.028). This suggests that the T102-allele might be involved in the complex circuits of nociception. However, the T102C polymorphism is not directly involved in the aetiology of FM but might be in linkage dysequilibrium with the true functional variant, which has to be unravelled.

Serotonin (5-HT) is a key neurotransmitter in the central nervous system. It is suggested that serotonergic dysfunction may be involved in the pathophysiology of fibromyalgia syndrome (FS). In this study, we aimed to investigate T102C polymorphism of the 5-HT2A receptor gene in FS. Fifty-eight patients with FS and 58 unrelated healthy volunteer controls were included in the study. In both groups, the C/C, C/T, and T/T genotypes of the 5-HT gene were represented in 31% (22.4% in controls), 50% (53.4%), and 19% (24.1%), respectively. The 5-HT2A receptor gene polymorphism results were not significantly different between patients and controls (chi squared test, P>0.05). There was a significant correlation between patients with the T/T genotype and the subgroup according to the SCL-90-R test, (analysis of variance, P<0.05). We also saw that patients with the T/T genotype had the lowest pain threshold. CONCLUSION. T102C polymorphism of the 5-HT2A receptor gene is not associated with the etiology of FS. Our results also indicate that the T/T genotype may be responsible for psychiatric symptoms of FS.

The aim of this study was to translate the Fibromyalgia Impact Questionnaire (FIQ) into Korean and to evaluate its reliability and validity for use with Korean-speaking patients with fibromyalgia (FM). After translating the FIQ into Korean, we administered it to 55 patients with FM (28 patients filled out the questionnaire again 7 days later) together with a Korean version of the Health Assessment Questionnaire (HAQ) and the Symptom Checklist-90-Revision (SCL-90-R). The tender-point count (TPC) was calculated from tender points identified by thumb palpation. In addition to sociodemographic characteristics, the severity of relevant current clinical symptoms, e.g., pain intensity, fatigue, and morning stiffness, were assessed by 10-cm visual analog scales (VAS). The test-retest reliability was between 0.466 and 0.780 (total 0.778). Cronbach's alpha was 0.800 for FIQ1 (the first assessment) and 0.857 for FIQ2 (the second assessment), indicating acceptable levels of internal consistency for both assessments. Significant correlations were obtained between the FIQ items, the HAQ, the severity of clinical symptoms, and the subscales of the SCL-90-R. In conclusion, the Korean version of the FIQ is a reliable and valid instrument for measuring health status and physical functioning in Korean patients with FM.

In women with fibromyalgia (FM), central nervous system (CNS) dysfunction in pain, mood, and sleep processes could be associated with changes in immune system indicators. The primary purpose of this study was to compare pain, psychological variables, subjective and objective sleep quality, lymphocyte phenotypes and activation markers, and natural killer activity (NKA) in midlife women with and without FM. A secondary purpose was to explore relationships among these variables in a step-wise regression. Subjects had pain pressure tender points assessed, completed a psychiatric interview and questionnaires (Beck Depression Inventory, SCL-90, Profile of Mood States, subjective sleep), and underwent polysomnograhic assessment for two consecutive nights. Lymphocyte phenotypes, activation markers, and NKA were assessed from blood drawn the morning after sleep laboratory night 2. Compared to controls, women with FM had lower pain thresholds, more psychological distress, higher depression scores, and reduced subjective and objective sleep quality. They also had fewer NK cells (p <.009) and more NK cells that expressed the IL-2 receptor (p <.04), but these differences were not statistically significant after correction for multiple comparisons. NKA was not statistically significantly lower in the women with FM compared to controls. In a multiple regression of age, tender point threshold, depression, psychological distress, and sleep efficiency, only the effect of group was significant (F = 5.479, p <.03) on NKA. In conclusion, we found little evidence to support the hypothesis that pain, mood, and sleep symptoms are associated with changes in the enumeration of peripheral lymphocytes or function in FM.
