Geriatric Depression Scale Calculator

Geriatric Depression Scale Calculator for Geriatrics. The output encourages clinical follow-up rather than labelling the person normal or definitely depressed. Concerning symptoms or safety concerns should not be dismissed because the total is below the screening boundary.

For shared guidance on choosing a tool and documenting results, read the clinical calculator workflow.

How this calculator works

This is a completed-total check for GDS-15. The developer identifies the original scale as public domain at https://web.stanford.edu/~yesavage/GDS.html; original English scoring and a follow-up threshold above five are at https://web.stanford.edu/~yesavage/GDS.english.short.score.html.

When to use this calculator

Review an older adult’s completed depression screen. First distinguish GDS-15 from the 30-item GDS and from the unrelated Global Deterioration Scale.

Inputs used

  • Complete GDS-15 total, integer 0-15
  • Confirmation of the 15-item depression instrument

Clinical interpretation

The output encourages clinical follow-up rather than labelling the person normal or definitely depressed. Concerning symptoms or safety concerns should not be dismissed because the total is below the screening boundary.

Worked example

A complete total of 5 lies below the developer’s above-five follow-up threshold; 6 triggers a follow-up-interview message. Neither number diagnoses depression. If only 12 responses were obtained, a subtotal of 5 is not automatically a completed total of 5.

Limitations and safety notes

No prorating or translated questionnaire is supplied. The developer notes uncertainty about translations and missing-item handling; this narrow workflow expects a complete original total. It does not assess suicide risk or establish a treatment plan.

Frequently asked questions

Does GDS 6 always refer to depression screening?

No. GDS can also mean Global Deterioration Scale. Check the full instrument name and version before interpreting any number.

  • Prefer original validation studies for scoring systems and prediction tools.
  • Use current specialty society guidance, transplant allocation policy, public health guidance, or regulator resources when they govern clinical use.
  • Include limitations and safety notes when a calculator is population-specific, context-dependent, or unsuitable as a standalone decision tool.
