Paano Kalkulahin si Geriatric Depression Scale

Ano ang Geriatric Depression Scale?

The Geriatric Depression Scale (GDS-15) Calculator scores 15 yes/no questions designed specifically for older adults to screen for depression, avoiding somatic symptoms that overlap with normal aging or medical illness.

Pormula

GDS-15 Score = Count of depressive responses (10 items: Yes=1; 5 items reverse-scored: No=1); Range: 0-15

TS: Total GDS-15 Score (points (0-15)) — Sum of depressive responses indicating depression severity
Ri: Item Response (0 or 1) — Binary depressive indicator per item after applying reverse scoring
SL: Severity Level (category) — Normal (0-4), Mild (5-8), Moderate (9-11), or Severe (12-15)

Mga Karaniwang Mali na Dapat Iwasan

✕Failing to reverse-score items 1, 5, 7, 11, and 13 where "No" indicates the depressive response
✕Using the GDS-15 with patients who have moderate-to-severe dementia — the tool requires sufficient cognitive function to answer reliably
✕Interpreting the GDS as diagnostic rather than as a screening tool that prompts further clinical evaluation

Mga madalas itanong

Why use the GDS instead of the PHQ-9 for older adults?

The GDS was specifically designed for elderly patients and uses simple yes/no questions without somatic items (sleep, appetite, fatigue) that overlap with normal aging and medical conditions, making it more specific for depression in this population.

Can the GDS be used with dementia patients?

The GDS-15 is valid for patients with mild cognitive impairment and mild dementia. For moderate-to-severe dementia, observational scales like the Cornell Scale for Depression in Dementia are more appropriate.
