Comparative Validation of Proxy-Based Montgomery-Ã sberg Depression Rating Scale and Cornell Scale for Depression in Dementia in Nursing Home Residents With Dementia

The proxy-based MADRS and CSDD did not differ in distinguishing depressed from nondepressed NH residents and may be used for screening purposes. For missing items, imputation of a lowest possib le item score may be applied. The MADRS and CSDD may be better used for ruling out rather than for ruling in depression.
