title: Assessing depression in fibromyalgia patients.
abstract: OBJECTIVE
  This study investigated the relationships among four methods of detecting depression in patients with fibromyalgia.
  
  
  METHODS
  Data were obtained from 100 women (mean age 43 years) who had been diagnosed with fibromyalgia. Instruments included a computerized Diagnostic Interview Schedule (C-DIS), Beck Depression Inventory (BDI), an adjusted "disease-free" BDI (BDI-A), and Minnesota Multiphasic Personality Inventory depression subscale (MMPI-D). Chance-corrected concordance, sensitivity, specificity, and accuracy among the four methods were calculated.
  
  
  RESULTS
  The C-DIS detected 22% and BDI-A 29% with current major depression. The BDI and MMPI-D yielded higher estimates of 55% of the 44%, respectively. Agreement on the diagnosis among the four methods was significantly greater than chance. When compared with the C-DIS, the BDI was the most sensitive instrument and the BDI-A most specific.
