Evaluating geriatric medical outpatients with the Beck Depression Inventory-Fastscreen for medical patients

To ascertain how effective the seven-item Beck Depression Inventory-FastScreen for medical patients (BDI-FS) was in screening geriatric (> 55 years old) patients for depression, the BDI-FS and the 15-item Geriatric Depression Scale (GDS-S) were administered to 33 (44%) male and 42 (56%) female outpatients who were scheduled for routine office visits by physicians specializing in geriatric medicine. The internal consistency of the BDI-FS was high (coefficient alpha = 0.83), and it was positively correlated with the GDS-S, r = 0.81, p < 0.001. The BDI-FS scores were not related to sex, age, ethnicity, or type of medical diagnosis, but were positively correlated with a diagnosis of depression (r = 0.49, p < 0.001) and being prescribed an antidepressant (r = 0.55, p < 0.001). A BDI-FS cut-off score of four and above had 100% sensitivity and 84% specificity rates, respectively, for identifying patients who were and were not diagnosed with depression.
