Fibromyalgia Not Related to Depressive Personality Type
This month's Annals of General Psychiatry (2007 Mar 9;6(1):9 ) includes an article on a study conducted to assess fibromyalgia patients' personality types. The study investigates the concept of fibromyalgia as a manifestation of depression or affective spectrum disorder. Researchers measured the cognitive styles of 44 fibromyalgia patients, 43 patients with major depressive disorder, and 41 healthy controls, using the Sociotropy and Autonomy Scale (SAS) and the Dysfunctional Attitude Scale (DAS) as well as the Beck Depression Inventory.
The study found that many fibromyalgia patients also suffer from depression, and thus have depressive personality styles. However, it also found that the population of fibromyalgia patients who do not suffer from major depression have personality styles similar to those of healthy individuals. The study concludes, "[t]hese findings suggest that a depressotypic personality style is related to depressive disorder, but not to fibromyalgia syndrome."
