Rasch Analysis of the Geriatric Depression Scale-Short Form

Abstract

We would recommend that the GDS-SF not be used as the sole method of screening for depression but incorporated into other clinical knowledge related to the geriatric patient in question, given that not all items are equally functional. The GDS-SF may be less effective as a screening tool but could be better used to detect a change in moderate levels of depression. Clinicians may also benefit by identifying person responses that misfit. If an individual provides responses that are atypical, the person might be referred to provide a more in-depth assessment of mental health status.
