Correlations between Scores on Chinese Versions of Long and Short Forms of the Geriatric Depression Scale among Elderly Chinese

A total of 187 elderly Chinese from the community were interviewed with the Chinese versions of the Geriatric Depression Scale-the long form and the short form. The scores on a proposed new version of the short form were also calculated. Cronbach alpha for the Geriatric Depression Scale-long form was .86. The correlations were significant between scores on the long and short forms (r = .94, p < .05) and between these on the long and new short forms (r = .91, p < .05). Cronbach coefficient alpha for the short form was .77 and for the new short form .81. Results of our study indicated that responding by these elderly persons on both short forms is acceptably internally consistent in comparison with those on the original Geriatric Depression Scale.
