Clinical characteristics of fibrositis. II. A “Blinded,” controlled study using standard psychological tests

Abstract

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.
