The C-SSRS (often referred to as "The Columbia") is a very comprehensive assessment of self-harm, suicidal thoughts, and suicide attempts. It was recommended by the Marine Corps to assess Marines who were contemplating ending their life. The tool is intended to identify the intensity of the need for additional clinical support (e.g. involuntary confinement). It should only be administered in person or over the phone and not sent via the Client Portal. If a client enters your office announcing they are contemplating suicide, you can use this tool to quickly gauge the severity of the ideation. If you end up using this tool and a problem appears evident, I strongly encourage using the Client Safety Plan Template (also in this forum) as a follow-up so the client has a plan in the event their suicidal thinking puts themselves at risk.
