The Geriatric Depression Scale by Lenore Kurlowicz,

Depressionis commonin late life, effectingnearly5 million of the 3 1 million Americansaged65 and older, Both major and minor depressionare reportedin 13%of community dwellingolder adults,24% of older medicaloutpatients,and 43% of both acutecareand nursinghome-dwelling older adults.Contraryto popularbelief, depressionis not a natural part of aging.Depressionoften is reversible with prompt and appropriatetreatment.However,if left untreated, depressionmay resultin the onsetof physical,cognitive,and socialimpairment and delayedrecoveryfrom medical illnessand surgery,increased healthcareutilization,and suicide.

administration.Scoresof 0 to 10 are considerednormal, 11 to 20 indicate mild depression,and 21 to 30 indicate severedepression. TARGET POPULATION: The GDSmay be usedwith healthy,medicallyill, and mild to moderatelycognitivelyimpairedolder adults.It hasbeenused extensivelyin community,acute,and long-term caresettings.

The GDSwas found to havea 92% sensitivity and a 89% specificitywhen evaluatedagainst diagnosticcriteria. The validity and reliability of the tool havebeensupported through both clinical practice and research. VALIDITY/RELIABILIT
