The Columbia-Suicide Severity Rating Scale (C-SSRS) is rapidly becoming the national and global standard in suicide risk assessment, proving more effective than other screening mechanisms previously introduced. C-SSRS is the only screening tool that assesses the full range of evidence-based ideation and behavior items, with criteria for next steps (e.g. referral to mental health professionals); thus, the C-SSRS can be exceptionally useful in initial screenings. Additionally, no formal mental health training is required to administer it.
Since its debut in 2007, C-SSRS has been endorsed by the National Action Alliance for Suicide Prevention and its definitions of suicidal ideation have been formally adopted by the Centers for Disease Control and Prevention. It has been requested or recommended by a host of federal and international agencies including the Food and Drug Administration, the World Health Organization, the Joint Commission, and the American Medical Association.
