The present study compared 30 patients with Fibromyalgia
Syndrome (FS) to 30 healthy control subjects matched for age,
sex, and estimated intellectual level on standardized measures
of attention, concentration, and memory as well as subjective
ratings of memory abilities and sleep quality. In addition, in
order to investigate the relationship between cognitive
functioning and other physical and psychological symptoms,
subjects with FS completed psychological measures of pain
severity, trait anxiety, and depression. Results indicated
that patients with FS performed more poorly on tests of
immediate and delayed recall, and sustained auditory
concentration, and their ratings of both their memory
abilities and sleep quality were lower than those of controls.
Furthermore, perceived memory deficits of the FS subjects were
disproportionately greater than their objective deficits.
Results indicated significant correlations between performance
on memory and concentration measures and scores on
questionnaires of pain severity and trait anxiety.
Implications of these results for multidisciplinary treatment
programs are discussed.
