Self-Harm and Suicide

In 30 seconds
Suicide — death caused by self-directed injurious behavior with intent to die — is one of healthcare's most feared and misunderstood topics. Self-harm, or Nonsuicidal self-injury (NSSI) Deliberate self-harm without intent to die, often for emotion regulation Full entry →, is different: deliberate damage to one's own body (commonly cutting, burning, hitting) without intent to die. NSSI is often a way of coping with overwhelming emotion; an attempt aims to end life. Confusing them is dangerous.
This topic gives you the tools to tell them apart, the language to ask safely, and the nurse's role: recognize, respond therapeutically, escalate, and follow facility policy. Crisis management is a team and policy matter, never solo improvisation.
Why this matters
Suicide is a leading cause of death globally and among the top causes in young adults in many countries. It is often preventable — and the people best positioned to help are often the people present: nurses. Most people who die by suicide have healthcare contact in the months before death.
Two facts should shape every nurse's practice: asking about suicide does not plant the idea — avoidance leaves people alone with their thoughts — and "people who talk about it won't do it" is a myth: talking about suicide is a warning sign.
The college version
Core Concepts
The spectrum of suicidal thoughts and behaviors
Clinicians distinguish along a spectrum: passive ideation (wishes for death without plan or intent), active ideation (thoughts of ending one's life), plan, intent, Suicide attempt Self-directed behavior with intent to die that does not result in death Full entry →, and suicide. Each step up raises urgency, but even passive ideation is assessed and reported.
Nonsuicidal self-injury: a different animal
NSSI is deliberate self-harm without suicidal intent. In most cases it functions as emotion regulation — releasing unbearable tension, punishing the self, or feeling something instead of numbness. It is associated with trauma and with conditions like borderline personality disorder (see Chapter 18), and — critically — is itself a risk factor for later suicide attempts. The nursing trap: labeling NSSI as manipulation — the distress underneath is real.
Warning signs and risk factors
Commonly cited warning signs (patterns, not proofs): burden talk, hopelessness, withdrawal, giving away possessions, increased substance use, sleep changes, recklessness — and mood improvement after deep depression, which can signal the decision has been made. Risk factors (probabilistic, not destiny): prior attempt (the strongest single predictor), depression, substance use, isolation, access to means (especially firearms), recent loss.
Classic studies: Durkheim and Shneidman (in context)
Émile Durkheim's Le Suicide (1897) founded the sociological study of suicide. Rather than interviewing individuals, he analyzed statistical records — suicide rates across regions, religious groups, and eras — finding rates stable within groups but different between them, and theorized that suicide is shaped by social integration and regulation — too little or too much of either. Read with its limits: methodologically, aggregate statistics cannot explain any individual death (the "ecological fallacy"); ethically, he studied the dead without consent — normal then, but a reminder of evolving research standards.
In the 1950s–60s, suicidologist Edwin Shneidman developed the Psychological autopsy Shneidman's method of reconstructing a death via interviews and records Full entry →: reconstructing the psychological state of a person who died by suicide by interviewing family, friends, and clinicians and reviewing records — often to clarify how the person died. It turned a death into data about preventable factors — undiagnosed depression, recent losses, communicated intent — showing that most people who die by suicide do communicate distress beforehand. Durkheim's gift to nursing: suicide is shaped by connection and belonging; Shneidman's: most people signal their pain before they act — hear the signal.
The nurse's role: recognize, respond, escalate
The crisis role is deliberately bounded:
- Recognize warning signs and ask directly, privately: "Are you having thoughts of ending your life?" Then: "Do you have a plan? Do you have access to what you'd need? Have you tried before?"
- Respond therapeutically: stay calm, listen fully, take the person seriously, validate the pain without validating suicide. Never promise secrecy — safety overrides confidentiality, and say so.
- Escalate: notify the provider/charge nurse immediately and follow facility policy — typically continuous observation, environmental safety (removing means per policy), and a clinician risk assessment. Never leave the person alone; never improvise.
- Document exact words, assessment, and every action.
Scope, policies, and legal frameworks (including involuntary-hold laws) vary by jurisdiction and institution — know your facility's policy before you need it. After a death by suicide, postvention — structured support for the bereaved — is itself prevention: the bereaved are at elevated risk, and staff carry moral distress.
How It Works / Step-by-Step Process
- Take it seriously and privately. Do not minimize, moralize, or change the subject. "I'm glad you told me. I want to understand."
- Ask the spectrum questions directly: thoughts of death? Thoughts of ending your life? A plan? Method? Access to means? A prior attempt?
- Assess supports: who knows, who is available, what has helped before.
- Do not promise secrecy: "I can't keep this between us — my job is to keep you safe, and that means telling the team." Say it kindly.
- Escalate immediately: notify the provider/charge nurse and follow facility policy (observation level, environmental safety, clinician risk assessment). Stay with the person — never leave them alone.
- Document exact words, your questions, their answers, and every action, then support the team's follow-up (safety plan, family notification per policy).
Common Confusions
| Do Not Confuse | With | Difference |
|---|---|---|
| Nonsuicidal self-injury | Suicide attempt | Intent: NSSI aims at emotion regulation, not death — though NSSI raises later attempt risk |
| Passive ideation | Active ideation | "Wish I wouldn't wake up" vs. thinking about acting; both get assessed and reported |
| Talking about suicide | Empty threat / manipulation | Talking about suicide is a warning sign — the "they won't do it" myth kills people |
| Asking about suicide | Planting the idea | Research consensus: direct questioning does not cause suicidal thoughts; silence leaves people alone with them |
| NSSI as "attention-seeking" | NSSI as distress | Even if it draws attention, the distress underneath is real; moralizing labels damage care |
| Suicide risk assessment | Crisis management | Assessment informs the team; crisis response is a facility-policy matter, never solo improvisation |
Eli explains
The same idea, in plain words
Explain it like I’m 10
Some people get so much pain inside that they think the only way to stop it is to hurt themselves or to die. That pain makes their brain play tricks — it tells them no one cares, or that everyone would be better off without them. Telling a grown-up you trust is the bravest thing you can do — that grown-up stays with you and gets help. The pain can be fixed, with time, medicine, and people who care.
Worked example
Nurse Osei is doing evening rounds when Mr. Whitfield, 47, being treated for pneumonia, says quietly: "Don't worry about me. Everyone's better off without me, anyway." She pulls the curtain, sits down, and asks: "That sounds like you're carrying a lot of pain. Are you having thoughts of ending your life?" His eyes fill. He admits he has been thinking about it for weeks, has a plan involving his garage, and has the means at home. He adds, "But I'd never do it. I'd never put that on my kids."
The nurse thanks him for trusting her, tells him plainly she cannot keep this to herself, and stays with him while a colleague notifies the provider. Per facility policy, Mr. Whitfield is placed on continuous observation, the provider completes a risk assessment, and the team coordinates next steps — including family contact and follow-up care. The nurse documents his exact words and every action. Nothing was improvised.
Key takeaways
- Ideation ≠ attempt ≠ death: passive → active ideation → plan → intent → attempt → death; each step raises urgency, and passive ideation still gets assessed and reported.
- NSSI is not a suicide attempt: usually emotion regulation without intent to die — but it is a risk factor for future attempts and is never "just attention-seeking."
- Ask directly — asking does not plant the idea. Avoidance and silence are the real dangers.
- "People who talk about it won't do it" is a dangerous myth. Talking about suicide is a warning sign.
- Classic studies: Durkheim (1897) — social integration shapes suicide rates (ecological fallacy limits); Shneidman — most people communicate distress before dying.
- Crisis role = recognize, respond, escalate, document: notify provider, follow facility policy, never leave the person alone, never improvise. Laws and policies vary by jurisdiction.

5 review questions from the chapter. Try each one, then open the answer.
What is the difference between NSSI and a suicide attempt, and why does it matter?
Show answer
NSSI is deliberate self-harm without intent to die — usually emotion regulation; a suicide attempt carries intent to die. They need different responses, but NSSI still raises future attempt risk and is never dismissed.
Why is "asking about suicide puts the idea in someone's head" considered a myth?
Show answer
Because decades of research show direct, compassionate questioning does not increase suicidal thinking — avoidance is the real harm.
Arrange in order of urgency: active ideation, passive ideation, plan + intent, attempt.
Show answer
Passive ideation → active ideation → plan + intent → attempt (each step up increases urgency; passive ideation still requires assessment and reporting).
What was Durkheim's methodological contribution and its main limitation?
Show answer
Durkheim analyzed aggregate statistics across social groups, showing suicide rates track social integration and regulation — the founding sociological method. Its limitation: the ecological fallacy — group data cannot explain individual deaths.
A patient tells you they are thinking about suicide. List the nurse's immediate actions.
Show answer
Take it seriously and privately, ask the spectrum questions (plan? means? prior attempt?), do not promise secrecy, stay with the person, notify the provider immediately, follow facility policy, and document exact words and actions.
