Columbia Suicide Severity Rating Scale
The Columbia-Suicide Severity Rating Scale is a brief clinician-administered assessment of suicide risk developed by Kelly Posner and colleagues at Columbia University to address limitations in prior screening tools. First published in the American Journal of Psychiatry in 2011, the C-SSRS has become the FDA-endorsed standard for monitoring suicidal ideation and behavior in antidepressant, anticonvulsant, and neuropsychiatric medication trials. The scale assesses both suicidal ideation (frequency and intensity) and suicidal behavior (attempts, preparatory acts) over defined time windows, providing structured risk stratification.
