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] The GDS is a multidimensional, multidisciplinary diagnostic and therapeutic activity that helps find patients at risk of/with depression.[3]
Depression is a serious and prevalent condition amongst older people. Depression in the elderly often overlooked and missed in assessment, delaying treatment and leading to possible harmful consequences. A robust tool that screens for depression can be an invaluable tool[3].
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.[4]
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.[5][6]
- 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% |
