What rating scale is used in the C-SSRS to measure the severity of suicidal ideation?

The Columbia – Suicide Severity Rating Scale (C-SSRS) employs a 0 to 5 scale to assess the severity of suicidal ideation. This scale is specifically designed to categorize the intensity and frequency of suicidal thoughts, providing clear descriptors for each level of ideation. The scale ranges from 0, indicating no suicidal ideation, to 5, which denotes active suicidal thoughts with a plan and intent. By using this specific scale, clinicians can more accurately gauge the risk level of an individual, allowing for informed decision-making regarding intervention and treatment options. The gradation in the scale allows for nuanced tracking of changes in suicidal thoughts over time, which is essential for ongoing risk assessment and management.
