Objective: The CES-D is an instrument that is commonly used to screen for depression in community-based studies of the elderly, but the characteristics of the CES-D in a residential home population have not yet been studied. The aim of this study was to investigate the criterion validity and the predictive power of the CES-D for both depressive and anxiety disorders in a vulnerable, very old population living in residential homes.
Methods: Two hundred seventy seven residents were screened with the CES-D, and subsequently interviewed with a diagnostic instrument, the Mini International Neuropsychiatric Instrument (MINI). The sensitivity, specificity, and positive and negative predictive value of the CES-D were calculated by cross-tabulation at different cut-off scores. Receiver Operating Characteristics (ROC) curves were used to assess the optimal cut-off point for each disorder and to asses the predictive power of the instrument.
Results: In a residential home population the CES-D had satisfactory criterion validity for depressive disorders and for any combination of depressive and/or anxiety disorders. With a desired sensitivity of at least 80%, the optimal cut-off scores varied between 18 and 22. The predictive power of the CES-D in this population was best for major depression and dysthymia (Area Under the Curve, AUC 0.87), closely followed by the score for any combination of depressive and/or anxiety disorder (AUC 0.86).
Conclusion: The use of one single instrument to screen for both depression and anxiety disorders at the same time has obvious advantages in this very old population. The CES-D seems to be a suitable instrument for this purpose.
