Geriatric Depression Scale (GDS-15 Short Form)
A 15-item yes/no questionnaire for screening depression in older adults. Higher scores indicate more depressive symptoms. A 5-item version (GDS-5) is also commonly used.
Warnings:
- GDS is a screening tool, not a diagnostic instrument
- Not validated for use in patients with moderate-severe dementia (Cornell Scale preferred)
- Somatic questions are intentionally excluded to avoid false positives from medical illness
- Score >=5 suggests depression; score >=10 is almost always indicative of depression
- Should be followed by comprehensive clinical interview for diagnosis
- Shorter versions (GDS-5, GDS-4) exist but may have lower accuracy
Note: GDS-15 questions selected from GDS-30 based on highest correlation with depression. GDS-5 alternative (cutoff >=2): Items 1, 4, 8, 10, 14 from GDS-15. Sensitivity ~94%, specificity ~81% for GDS-5. The scale is in the public domain.
