Abstract:
Depression is one of the commonest psychiatric illness in the elderly. Screening instruments of depression can greatly facilitate its identification in the community, leading to early recognition and diagnosis. The Geriatric Depression Scale was translated into Chinese and its reliability, validity and factor structure examined in a population of Chinese elderly in Hong Kong. One hundred and thirteen normal and 80 depressed elderly subjects were studied and a cut-off score of 15 on the scale was found to be optimal. The scale's reliability and validity was satisfactory and thus it is a promising instrument for screening geriatric depression in Hong Kong.
