Підсумок	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.	The Patient Global Impression of Change is a single-item, seven-point rating scale asking patients to report their overall impression of change since treatment initiation. Originally published by William Guy in the ECDEU Assessment Manual in 1976, the PGIC has become a standard co-primary endpoint in clinical trials assessing treatment efficacy. The scale is endorsed by the FDA as a patient-reported outcome measure for demonstrating clinical benefit. Despite its simplicity, the PGIC captures patients' holistic perception of improvement—integrating symptom reduction, functional recovery, and subjective well-being.
