TL;DR

The purpose of this study was to examine the unidimensionality, item fit, redundancy and differential item functioning (DIF) of the 15‐item version of the Geriatric Depression Scale (GDS) in a community sample of 300 Hong Kong Chinese patients with pneumoconiosis.

Abstract

Although the GDS was overall unidimensional, there was evidence of item redundancy indicating that a shortened version would be as adequate as the original version.
