摘要	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 PHQ-9 is a brief, nine-item self-report questionnaire developed by Kroenke, Spitzer, and Williams to screen for and measure the severity of depressive symptoms. Published in 2001 in the Journal of General Internal Medicine, it has become one of the most widely used depression screening instruments globally. The scale maps directly to DSM-IV diagnostic criteria for major depressive disorder, making it valuable in both clinical and research settings.
