How you may use it
Free to use in healthcare and community settings with no special permission, including in an electronic record, and each organization may set its own next steps for each risk level. The core questions must not be changed; use the official versions and translations from the Columbia Lighthouse Project.
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.

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.
C-SSRS result: low risk at a clinic visit
Student health clinic, follow-up visit, screener recent on the check-in tablet
Answers
24-year-old graduate student. Yes to questions 1 and 2: she has wished she could disappear and had brief thoughts of killing herself on two nights this month, during exams. No to questions 3, 4, and 5: no method, intent, or plan. No to question 6: no suicidal behavior ever. Highest yes: 2.
Risk level
Low risk: question 2, past month, nothing higher. The nurse practitioner went through it at the same visit: the thoughts are fleeting, come late at night, and pass by morning. No past attempts. She lives with two roommates and talks to her sister daily.
Actions taken
Safety plan written together: her warning signs, a run or a call to her sister, the campus counseling center, and 988 by call or text. Means safety: no firearms; only a small bottle of ibuprofen at home. Referral to counseling, first appointment Thursday. Clinic follow-up in 2 weeks.
Who was told
The medical assistant told the nurse practitioner before the visit began. She chose not to involve family for now; her sister is on the safety plan as a contact. Next screen: since-last-contact version at the 2-week visit.

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.
Dictated after triage
“C-SSRS at triage: yes through question 4, no plan, no past attempts.”
“High risk. He’s in the safe room with a sitter, and psychiatry is on the way.”
Vero Scribe records the C-SSRS result in your template from the visit, with the patient’s consent, or from your dictation: the questions answered yes, the timeframe, the risk level, and what you did. You review and edit every line, then copy it into your record. Vero works in 60+ languages.
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.
