Abstract

Objective To empirically evaluate the psychometric properties of the 15-item Geriatric Depression Scale (GDS-15); determine the optimal cutoff points and screening performance for the detection of major depression; and examine differential item functioning (DIF) to determine the variability of item responses across sociodemographics in an elderly home care population.Design A secondary analysis of data collected from a random sample study.Setting Homebound subjects newly admitted over a 2-year-period to a large visiting nurse service agency in Westchester, New York.Participants Five hundred twenty-six subjects over age 65, newly admitted to home care for skilled nursing.Measurements Major depression was diagnosed using both patient, Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, and best estimate procedures. Self-report measures included the GDS-15, activities of daily living (ADL), instrumental ADL, and pain intensity. Cognitive impairment was assessed using the Mini-Mental State Examination and medical morbidity using the Charlson Comorbidity Index.Results Optimal cutoff (5) yielded sensitivity 71.8% and specificity of 78.2%, however, the accuracy of the GDS-15 was not influenced by severity of medical burden. Persons with a cluster of ailments were twice as likely (Adj odds ratio = 2.47; 95% confidence interval = 1.49-4.09) to be diagnosed with depression. DIF analyses revealed no variability of item responses across sociodemographics.Conclusion Main findings suggest that the accuracy of the GDS-15 was not influenced by severity of clinical or functional factors, or sociodemographics. This has broad implications suggesting that the very old, ill, and diverse populations can be appropriately screened for depression using the GDS-15.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
