What to know

1

The C-SSRS is one of the most widely used suicide risk screeners. It helps you identify whether someone is at risk and how severe that risk is, across the full range of suicidal ideation and behavior.

2

The right version and timing matter. Establish a lifetime and recent baseline at intake, use brief follow-up screens consistently, and reassess when a client’s presentation changes.

3

Document what the client endorsed, how you interpreted it, what you did next, and why you made those choices. Headway’s note templates and EHR can help keep that record consistent.

Introduction

Picture this: A client starts telling you about suicidal thoughts, and your heart speeds up. Most of that anxiety stems from caring for them. But another part of it, if you're honest, is fear about what this means for your license and practice. I've felt both in my own practice.

What can bring some calm is knowing your tool: the Columbia-Suicide Severity Rating Scale (C-SSRS), including what it measures, which version fits your practice, what each risk level calls for, and how to document it.

What is the Columbia-Suicide Severity Rating Scale (C-SSRS)?

The Columbia-Suicide Severity Rating Scale, also called the Columbia Protocol, is a free set of plain-language questions that help you identify whether someone is at risk for suicide, gauge how severe and immediate that risk is, and decide what level of support they need. The six-item screener takes a few minutes, and anyone can ask it, though Columbia recommends taking its free training before administering it.

Before the C-SSRS, risk assessment leaned on attempt history. It was the first scale to rate the whole range, from passive ideation to behavior. Researchers at Columbia, the University of Pennsylvania, and the University of Pittsburgh built it with NIMH support for a 2007 study. It's available in more than 150 country-specific languages.

The C-SSRS questions and what each one measures

The six-item screener moves from suicidal thoughts to behavior. Its skip logic means not everyone is asked every question.

1. Passive ideation: Screens for a wish to be dead or not wake up, without necessarily thinking about suicide.

2. Active ideation without specifics: Screens for thoughts of suicide. If the answer is no, the screener skips items 3–5 and goes to item 6, regardless of the answer to number 1.

3. Ideation with method: Asks whether the person has thought about how they might act, even without a specific plan or intent.

4. Ideation with some intent to act: Asks whether there's some intention to act on the thoughts.

5. Ideation with a specific plan and intent: Assesses whether the person has worked out details of a plan and intends to carry it out.

6. Suicidal behavior: Screens for past actions, including preparation for suicide or a suicide attempt. If the answer is yes, a follow-up asks whether it happened within the past three months, since recent behavior carries more weight.

Plain, direct wording gets clearer answers, and asking directly doesn't plant the idea or increase suicidal thoughts.

How the C-SSRS is scored: Ideation severity, intensity, behavior, and lethality

  • Severity of ideation: An ordinal ladder rates the most severe suicidal thought endorsed on a 5-point scale: 1 (wish to be dead), 2 (nonspecific active thoughts), 3 (thoughts with methods), 4 (intent without plan), 5 (intent with a specific plan). It is scored 0 if none are endorsed.
  • Intensity of ideation: Rates frequency, duration, controllability, deterrents, and reasons for ideation, each on a 5-point scale.
  • Behavior subscale: This distinguishes actual, interrupted, and aborted attempts, preparatory behavior, and nonsuicidal self-injury.
  • Lethality subscale: Rates actual medical damage of an attempt on a 6-point scale. When actual lethality is 0, potential lethality is rated on a 3-point scale.

C-SSRS scoring differs by version. The screener skips intensity and lethality and maps item responses, including recency, directly to low, moderate, or high risk. The full scale's added detail still matters clinically: a 2026 meta-analysis found that prior suicidal behavior and ideation severity predicted future non-fatal attempts.

Which version of the C-SSRS should you use?

  • C-SSRS screener (screen version): A brief, 6-item, ideation-and-behavior check with triage categories of low, moderate, and high risk. It’s best for intake, routine screening, and fast risk identification if a client mentions SI.
  • Full scale (lifetime/recent): Captures the intensity of ideation, behavior-type, and attempt lethality subscales. It records lifetime history alongside recent months. Use it at intake for a baseline or after a positive screen.
  • Since last contact or since last visit: Captures changes since the previous assessment. It is best used for follow-up visits and ongoing monitoring.
  • Pediatric version: The standard pediatric version is used with children as young as 6, and a separate version with simpler language covers ages 4–5.
  • Risk assessment versions: Combines C-SSRS items with risk and protective factors, treatment history, and activating events. Use it when you need a broader documented assessment to guide treatment planning.

For a private-practice workflow, it can be good practice to use a screener (including the lifetime/recent version) at intake and a since-last-visit form at recurring appointments. Escalate to a fuller risk assessment and setting-appropriate safety response when active ideation is endorsed, particularly with intent, a plan, or recent suicidal behavior.

When and how often to administer the C-SSRS in private practice

  • Intake baseline: Use the lifetime/recent version at the first visit. Without a baseline of past behavior and peak ideation, a later positive screen is hard to read as a chronic pattern or a new escalation.
  • Recurring sessions: The Action Alliance's Recommended Standard Care calls for assessing risk with a standardized scale at intake and whenever clients are seen. In outpatient practice, the since-last-visit screener is a realistic way to do that without repeating the full assessment.
  • Trigger-based screening: Screen outside the regular frequency whenever clinical events raise concern: new or worsening depressive symptoms, hopelessness, insomnia, agitation, substance use relapse, a significant loss, or activating event, hospital discharge or care transitions, or any new suicidal ideation.

Using the same instrument consistently at every contact is what shows a consistent picture of a client's trajectory. This picture is based on comparable data from repeated questions rather than a general impression or data based on different questions.

What to do after a positive screen: Turning risk level into next steps

Columbia's screener with triage points sorts responses into low, moderate, and high risk. The Action Alliance's Recommended Standard Care describes the actions that usually follow each risk level. These are common thresholds, not direct clinical guidance. Each practice sets its own.

  • Low risk (wish to be dead or nonspecific active thoughts only, with no method, intent, plan, or recent behavior): Document the items endorsed. Reinforce reasons for living and existing supports, share crisis line information, and set a routine re-screen at the next scheduled contact.
  • Moderate risk (thoughts with a method, or suicidal behavior more than three months ago): Conduct a comprehensive suicide assessment, complete a collaborative written safety plan during the same visit, provide lethal means counseling (which may include family in reducing access), consider increasing session frequency, and coordinate with other treating clinicians with the client's consent.
  • High risk (intent, a plan with intent, or suicidal behavior in the past three months): Perform a same-day suicide-specific evaluation, do not end the session without a clear disposition, create or update the safety plan during that session, and call 911, involve crisis services or arrange emergency evaluation when the client can’t stay safe in the outpatient setting.

Decide your thresholds, consultation contacts, and local crisis and emergency options before you need them, so you're not improvising in a high-risk moment. Use a collaborative safety plan rather than no-harm contracts, which lack evidence of effectiveness.

A screen like the C-SSRS informs, but never replaces, clinical judgment. For between-session support, clients can call or text the 988 Suicide & Crisis Lifeline, or text HOME to 741741 for Crisis Text Line. If someone is in immediate danger, call 911.

How to document a C-SSRS screen so it holds up to review

After a session of working with suicidality, clinicians can still feel nervous about their documentation and what to note in order to provide the most protection to their license and practice. “Denies SI” records a conclusion, but little about what was asked, whether behavior was assessed, or why the response was appropriate. A defensible note lets another clinician, a clinical board, or an auditor follow your assessment and decision-making.

  • What to record: Name the C-SSRS version and timeframe, specific items endorsed or denied (ideation, method, intent, plan, behavior), relevant recency, risk determination (low/moderate/high), and how that determination was made.
  • Document the intervention: Record the actions taken related to the risk level: collaborative safety plan, means-safety counseling, crisis line information provided, coordination with other treating clinicians, and the defined follow-up interval.
  • Record your reasoning: Board and malpractice reviews typically ask whether risk was reasonably assessed and whether your response fit what you found. A written rationale shows both.
  • Medical necessity: Documented risk, assessment, and interventions can support the level of care billed and tie the session to a clear clinical rationale.
  • Consistency: Standardized risk language and the same screen each session make the trajectory easy to follow and close gaps from varied phrasing.

Consistent, individualized documentation can help substantiate claims and reduce avoidable denials or clawbacks, though it cannot guarantee either outcome.

How to actually ask the questions out loud

  1. Normalize before you ask: Explain that you ask everyone these questions to understand how best to support them and it is not a reaction to something they said.
  2. Read the items as written: Use the form’s direct wording to reliably identify the risk. Vague or softened questions may leave you with unclear answers or under-detected risk.
  3. Slow down on a yes: Pause, then invite the client to describe the thought or behavior in their own words (e.g., what the thought was, when it occurred, how often).
  4. Manage your own reaction: Keep your voice calm and nonjudgmental, even if the responses are alarming, so the client knows you can hear an honest answer. Visible anxiety or alarm can signal that what they’re disclosing is unwelcome and discourage further honesty. A composed presence helps protect future disclosure and engagement.
  5. Lead with curiosity, not problem-solving: Listen and clarify what the client means before moving to next steps. Jumping immediately to solutions or safety logistics before the client feels understood can shut down what they were about to tell you.
  6. Explain confidentiality limits up front: Cover them in the first session and again when you introduce the screen.

Free administration training is available through Columbia University's Lighthouse Project, and suicide risk assessment continuing education is now required for licensure in a growing number of states. Check your state board’s specific CE rules.

C-SSRS vs. other suicide risk screening tools

  • PHQ-9 item 9: The depression screener's final item (like item 9 on the BDI-II) flags thoughts of death or self-harm. Treat a yes as a prompt for further assessment, not a substitute for asking about intent and behavior. Item 9 can over-identify risk compared with the C-SSRS.
  • ASQ: A four-item yes/no screen that rapidly assesses suicide risk. It is most studied in pediatric primary care, inpatient, and emergency settings. Its brief structure best suits high-volume triage.
  • Scale for Suicide Ideation: A 19-item scale that measures the intensity of current ideation (wish to die, wish to live, duration, intent) on a 0–38 range. It measures ideation depth in more granular detail but does not characterize behavior as the C-SSRS does.
  • SAFE-T: A five-step clinical framework (identify risk factors, identify protective factors, inquire directly, determine risk level and intervention, document) and not an assessment tool. It pairs with the C-SSRS (the direct-inquiry step can use C-SSRS items).

For outpatient practice, the C-SSRS is free, spans all ages, is fairly brief, distinguishes ideation severity from behavior and lethality, and offers the ability to track change over time. The CDC adopted its definitions of suicidal behavior, the FDA uses it as the standard for measuring suicidality in clinical trials, and the VA/DoD's 2024 guideline suggests the screener. Whichever tool you pick, use it across your whole caseload.

FAQs about the C-SSRS

Is the C-SSRS free to use?

Yes, it’s free for clinical, community, health care, and nonprofit use, including all versions. For other uses, contact the Columbia Lighthouse Project directly to discuss.

Do you need special training or a particular license to administer the C-SSRS?

No C-SSRS-specific license or advanced training is required for clinical screening. Columbia recommends its free training.

How long does a C-SSRS screen take?

The screener usually takes a few minutes, and the full scale takes longer. A 'no' on items 1 and 2 skips straight to item 6.

Does asking clients about suicide increase their risk?

No. A systematic review found no statistically significant increase in suicidal ideation from being asked directly and suggested that acknowledging and talking about suicide may actually reduce it.

Can the C-SSRS be administered during a telehealth session?

Yes. Confirm the client's physical location at the start, know the crisis and emergency resources there, and plan in advance how you'd get help to them after a high-risk disclosure.

Can you bill for administering a suicide risk screening?

Sometimes. CPT 96127 describes a brief standardized emotional or behavioral assessment with scoring and documentation. Document the C-SSRS version, results, clinical response, and why the assessment was needed. Don't assume it's separately billable during a therapy visit. Eligible codes, coverage, allowable units, and same-day billing rules vary by payer and plan. (Note: You cannot bill this code as a Headway provider.)

How to write progress notes

Progress notes are the core piece of documentation a provider should write after each client session, but it’s more than just a record of what happened.
