Geriatric Depression Scale

Objective[edit | edit source]

The Geriatric Depression Scale (GDS) is a patient-reported outcome measure created by Yesavage et al. in 1982 to screen for depressive symptoms among older adults.[1][2]

Originally, this screening tool has 30 items, but several shorter versions were also developed: GDS 15, GDS 10 and GDS 4.

Intended Population[edit | edit source]

The scale is intended for the geriatric population (aged 60 years or more). It can be used for healthy, medically ill, and cognitively impaired older adults.[3]

Method of Use[edit | edit source]

Equipment required: Questionnaire and pen

Instructions: Choose between yes or no regarding how you felt over the past week

Scoring:

GDS 30

  • 0 - 9 = Normal
  • 10 - 19 = Mild Depression
  • 20 - 30 Severe Depression


GDS 15

  • 0-4 = Normal
  • 5-8 = Mild Depression
  • 9-11 = Moderate Depression
  • 12-15 = Severe Depression

Evidence[edit | edit source]

Reliability[edit | edit source]

  • Studies reported GDS 30 and GDS 15 to have excellent internal consistency, both having Cronbach alpha coefficient of 0.92.[4][5]
  • Limited studies are found about GDS 10 and GDS 4. Further research is needed to establish the reliability of these shorter forms.

Validity[edit | edit source]

In a 2020 systematic review and meta-analysis, all versions of GDS were found to be useful for determining depression among older adults:[1]

GDS version Sensitivity Specificity
GDS 30 82% 76%
GDS 15 86% 79%
GDS 10 87% 75%
GDS 4 74% 71%
