Agreement between CES-D and CIDI-SF scales of depression among older adults: a cross-sectional comparative study based on the longitudinal aging study in India, 2017-19

Quick takeaway

This LASI-based study shows how much case counts can shift depending on which depression scale is used, which matters directly for screening programs and capacity planning.

Why this matters

Useful for preventing measurement-driven over- or under-identification in geriatric mental-health workflows.

Key caution

Agreement studies help with calibration, but they do not replace validation against a clinical gold standard.
