How does the Columbia-Suicide Severity Rating Scale (CSSRS) function in practice?

• A. A questionnaire to measure depression severity.
• B. A scale to determine residential placement risk.
• C. A structured interview tool to assess intensity and immediacy of suicidal ideation and behavior.
• D. A tool to assess family functioning.

Answer: (C)

The main idea is that the CSSRS is a structured way to evaluate how severe someone’s suicidal thoughts are and how close in time a risk might be. In practice, a clinician administers a standardized interview (or uses the self-report form) that walks through both thoughts and behaviors related to suicide. It starts by distinguishing passive wishes or thoughts of death from active suicidal thoughts that include intent, a plan, and access to means. It then covers any actual suicidal behaviors, such as completed, aborted, or interrupted attempts, and any preparatory actions. The questions also note when these experiences occurred (recent vs. lifetime) and how imminent the risk feels to the person.

All of this information is used to generate a risk assessment: how severe the ideation is, how immediate the danger might be, and what level of intervention is needed—ranging from safety planning and closer monitoring to urgent emergency care. It’s not a general measure of depression severity, nor a tool for judging family functioning or residential placement by itself.
