C-SSRS: Columbia Suicide Severity Rating Scale

The C-SSRS asks up to six plain questions about suicidal thoughts in the past month and suicidal behavior, and the highest yes sorts the answers into low, moderate, or high risk. See what each question covers, how the risk levels work, and where to get the official form, then record the result with the free template.

What the score means. 0 to 6, highest screener question answered yes.

0: None

No to every question asked: no suicidal thoughts in the past month and no suicidal behavior. Carry on with the visit and rescreen when your policy says.

1 to 2: Low risk

A wish to be dead, or general thoughts of suicide, with no method, intent, plan, or recent behavior. Talk it through, make a safety plan, and refer to behavioral health.

3: Moderate risk

Thoughts about how they might do it, without intent or a plan. A clinician assesses suicide risk the same day, with a safety plan and means safety.

4 to 6: High risk

Intent to act, a plan with intent, or suicidal behavior in the past 3 months. Stay with the person, remove means, and arrange an emergency evaluation now.
  • The screener has no total. The result is the highest question answered yes, and for the behavior question, when it happened.
  • Questions 1 to 5 cover the past month. Question 6 asks about suicidal behavior over the person’s lifetime, then whether it was within the past 3 months.
  • If question 2 is no, questions 3 to 5 are skipped, and question 6 is still asked.
  • Question 6 counts as high risk only when the behavior was within the past 3 months. Behavior longer ago is a lifetime yes, which Columbia’s triage versions rate as moderate risk unless a higher question was also yes.
  • Columbia counts any high-risk answer as a positive screen: yes to question 4 or 5 in the past month, or behavior in the past 3 months.
  • The levels are the ones Columbia’s triage versions and the SAFE-T protocol use. What follows each level differs by setting, and each organization sets its own responses for low, moderate, and high risk to fit its resources and policies.
  • The full scale also rates how intense the worst thoughts were and how lethal any attempt was. Record those from the official form; they don’t change the screener level.

How to give it, score it, and read it.

Choosing the version

Columbia publishes short screeners for triage and a full scale for detailed assessment, in recent, lifetime, and since-last-contact forms, with versions for specific settings.

  • The screener for universal screening and triage
  • The full scale when a clinician needs the intensity of the thoughts and the details of any attempt
  • A since-last-contact version to recheck the same patient each shift or each visit
  • The setting version that matches yours: emergency department, inpatient, primary care, outpatient, schools, or corrections

Avoid: Writing your own version of the questions into a form or the record. The core questions are fixed; download the official version.

Asking the questions

Ask them as written, somewhere private, in a calm and direct voice. Columbia says no mental health training is needed to ask them.

  • Ask the first two questions of everyone you screen
  • Follow the skip pattern: if question 2 is no, go straight to the behavior question
  • Ask the behavior question every time, then whether it was within the past 3 months
  • Use an official translation or a trained interpreter, not a translation made on the spot

Avoid: Softening the words into “You’re not thinking of hurting yourself, are you?” A leading question invites a no.

Finding the risk level

The highest question answered yes, and when any behavior happened, set the level.

  • Question 1 or 2 only: low risk
  • Question 3, or behavior more than 3 months ago: moderate risk
  • Question 4 or 5, or behavior within the past 3 months: high risk
  • Clinical judgment can raise the level or change the response; write down why

Avoid: Lowering the level because the patient says they feel better now. Record the answers as given, then add your own view beside them.

Acting on the level

Each organization sets what follows each level. The usual pattern rises with the risk.

  • Low: talk it through, make a safety plan, give 988 and local crisis contacts, and refer to behavioral health
  • Moderate: a same-day suicide risk assessment by a trained clinician, with a safety plan and means safety
  • High: stay with the person, remove means, and arrange an emergency evaluation; in hospital, start your observation protocol
  • Ask about firearms and stored medicines at every level above none

Avoid: Ending at the screen. A moderate or high result starts a full suicide risk assessment; it doesn’t replace one.

Screening again

Recheck with a since-last-contact version, so each screen covers the time since the last one.

  • Rescreen at set points, such as each shift on an inpatient unit, before discharge, and at follow-up visits
  • Compare with the last screen, and record what changed
  • Rescreen sooner after a loss, a crisis, or a change in medicines

C-SSRS result: high risk at emergency triage

Emergency department, universal screen by the triage nurse, screener recent with triage points

Answers

52-year-old man brought in by his sister for not eating or sleeping since his business closed. Asked in a private room, in English. Yes to questions 1 to 4: he wishes he were dead, has thought of killing himself most days this month, has thought of taking his stored oxycodone, and says he would act on it “if nothing changes.” No to question 5: no worked-out plan. No to question 6, lifetime. Highest yes: 4, past month.

Risk level

High risk: question 4, intent, within the past month. The emergency physician saw him within 15 minutes and agreed with the level.

Actions taken

Moved to a safe room; belongings searched and secured; constant observation by a sitter. Full suicide risk assessment by the physician and the psychiatry consult team. His sister removed the oxycodone and his hunting rifle from his home and confirmed both are locked at her house. Psychiatry recommended voluntary admission; he agreed, and a bed was requested on the psychiatric unit.

Who was told

Charge nurse and emergency physician told at 14:10, at the screen. Psychiatry paged at 14:25. His sister told of the plan, with his agreement. Next screen: since-last-contact version each shift while he is in the department.

Common mistakes, and how to avoid them.

Rewording the questions

Gentler words change what the questions find, and the core questions may not be altered. Read them as written from the official form.

Skipping the behavior question

Question 6 is asked even when question 2 is no. Someone with no thoughts today can still have made an attempt last month, which is high risk.

Leaving out when it happened

An attempt last month and one 10 years ago lead to different levels. Ask whether it was within the past 3 months, and write the date.

Writing only “C-SSRS positive”

Record which questions were yes, the timeframe, and the level, so the next clinician knows what was found and what was done.

Stopping at the screen

Every level above none needs the response your organization has set, and a moderate or high result leads to a full suicide risk assessment.

Frequently asked questions.

How do you score the C-SSRS?

The screener has no total. Note the highest question answered yes and, for question 6, whether the behavior was within the past 3 months. Question 1 or 2 alone is low risk; question 3, or behavior longer ago, is moderate; question 4, 5, or behavior in the past 3 months is high. The full scale adds ratings of how intense the thoughts are and how lethal any attempt was.

What do the C-SSRS risk levels mean?

Low risk is a wish to be dead or general thoughts of suicide, without a method, intent, plan, or recent behavior. Moderate risk adds thoughts about a method, or behavior more than 3 months ago. High risk is intent, a plan with intent, or behavior in the past 3 months. Each organization decides what it does at each level; high risk usually means staying with the person and an emergency evaluation.

What counts as a positive C-SSRS screen?

Columbia counts any high-risk answer as positive: yes to question 4 or 5 in the past month, or suicidal behavior in the past 3 months. Most organizations also respond to low and moderate answers, with a safety plan, means safety, and a referral.

What versions of the C-SSRS are there?

The screener asks 2 to 6 questions, depending on the answers, and is used for triage. The full scale adds intensity ratings and attempt details, in lifetime and recent, baseline, and since-last-visit forms. There are versions for emergency departments, inpatient units, primary care, schools, and corrections, versions for young children, and translations in more than 100 languages.

How is the C-SSRS different from PHQ-9 item 9?

PHQ-9 item 9 is one question about thoughts of death or self-harm, inside a depression questionnaire. The C-SSRS asks only about suicide, separates thoughts, method, intent, plan, and behavior, and gives a risk level. Many clinics follow a positive item 9 with the C-SSRS.

Who can give the C-SSRS?

Columbia says anyone can ask the questions and no mental health training is needed: nurses, physicians, medical assistants, counselors, teachers, and first responders all use it. Free training is on the Columbia Lighthouse Project site. A clinician makes the full risk assessment and plan that follow a moderate or high result.

Is the C-SSRS free to use?

Yes, in healthcare and community settings and in nonprofit or publicly funded research, with no special permission needed. Download the official version for your setting, and its translations, from the Columbia Lighthouse Project, and don’t change the core questions. The recording template on this page is free to copy or download.
