N. Herrmann et al., A VALIDATION-STUDY OF THE GERIATRIC DEPRESSION SCALE SHORT-FORM, International journal of geriatric psychiatry, 11(5), 1996, pp. 457-460
The validity of the Geriatric Depression Scale (GDS) short form was as
sessed in a geriatric affective disorders outpatient clinic (N = 116).
The GDS was highly correlated with the Montgomery Asberg Depression R
ating Scale (MADRS), and with optimal cutoff scores of 5/6, demonstrat
ed a sensitivity of 85% and a specificity of 74.0%. The GDS appears to
be a useful, valid screening instrument in this population.
