Depression Screening for Seniors – Geriatric Depression Scale & PHQ-9
Depression is not a normal part of aging – but it's one of the most common and treatable mental health conditions in older adults. Many seniors with depression are undiagnosed because symptoms are mistaken for "normal aging" or other conditions. Regular depression screening can identify treatable depression early and significantly improve quality of life. This guide covers the Geriatric Depression Scale (GDS), PHQ-9 screening tool, risk factors, and treatment options for older adults.
seniors in India experience depression – but fewer than 10% receive adequate treatment. Depression in older adults is often overlooked, leading to unnecessary suffering and decreased quality of life.
Why Depression Screening Matters
Depression in seniors is often missed or misdiagnosed because symptoms can overlap with other conditions – or be dismissed as "normal aging." Regular screening can:
- Identify depression early – when treatment is most effective.
- Prevent unnecessary suffering – depression is treatable.
- Reduce complications – depression worsens physical health conditions.
- Improve quality of life – for seniors and their caregivers.
- Prevent suicide – older adults have the highest suicide rates.
Depression Screening Tools for Seniors
Two of the most commonly used screening tools are the Geriatric Depression Scale (GDS) and the PHQ-9.
| Tool | Number of Questions | Administration | Strengths | Cut-off Score |
|---|---|---|---|---|
| Geriatric Depression Scale (GDS-15) | 15 questions | Self-administered or clinician-administered | Simple yes/no format, designed specifically for seniors | ≥ 5 |
| PHQ-9 | 9 questions | Self-administered | Also assesses severity, widely used in primary care | ≥ 10 |
| GDS-30 | 30 questions | Self-administered or clinician-administered | More comprehensive, longer version | ≥ 11 |
| PHQ-2 | 2 questions | Self-administered | Ultra-short screening – first step | ≥ 3 |
Geriatric Depression Scale (GDS-15)
The GDS-15 is a simple 15-question screening tool designed specifically for older adults. Answer yes/no to each question.
Scoring: Count the answers that indicate depression. For questions 1, 5, 7, 11, and 13, a "no" answer indicates depression. For all other questions, a "yes" answer indicates depression. A score of 5 or more suggests possible depression – further evaluation is needed.

Depression vs. Dementia – What's the Difference?
Depression and dementia can have overlapping symptoms – but they are different conditions. Here are some key distinctions:
- Onset: Depression often has a more rapid onset; dementia is usually gradual.
- Cognitive changes: In depression, memory problems often improve with treatment; in dementia, they are progressive.
- Awareness: People with depression are often aware of their cognitive difficulties; people with dementia may not be.
- Mood: Depression is characterised by persistent low mood; dementia may not involve mood changes.
- Important: Depression can also co-exist with dementia – and treating depression can improve function.
