Adolescent Suicide Assessment and Safety Planning

Overview

Suicide is the second leading cause of death among youth ages 10-24 in the United States. Youth suicide rates have increased approximately 30% since 2000, with a particularly sharp rise since 2007. Comprehensive risk assessment, lethal means counseling, and safety planning are core clinical competencies for child and adolescent psychiatrists. No prediction model can reliably identify which specific individuals will die by suicide — the goal is risk stratification to guide clinical decision-making and resource allocation.

Epidemiology

Approximately 2,700 youth ages 15-19 die by suicide annually in the United States. About 9% of high school students report at least one suicide attempt in the past year, and approximately 20% report serious suicidal thoughts. Firearms account for approximately 50% of youth suicide deaths, suffocation and hanging for approximately 30%, and poisoning for approximately 8%. Demographically, males complete suicide at approximately 3-4 times the rate of females, while females attempt suicide at approximately 2-3 times the rate of males. LGBTQ+ youth face a 4-6 fold increased risk of suicide attempts compared to heterosexual peers. Suicide rates among Black youth have increased more rapidly than in other demographic groups, and American Indian/Alaska Native youth have the highest suicide rates of any racial or ethnic group.

Risk Factors

Static (Historical) Risk Factors

The strongest single predictor of future suicide death is a previous suicide attempt. Other static risk factors include family history of suicide or suicide attempts, history of non-suicidal self-injury, prior psychiatric hospitalization, history of abuse or trauma (with sexual abuse being particularly associated), LGBTQ+ identity (due to minority stress rather than orientation itself), access to lethal means (particularly firearms), and a history of impulsive aggression.

Dynamic (Modifiable) Risk Factors

Dynamic risk factors, being modifiable, are the primary targets of clinical intervention. These include current suicidal ideation (assessed by frequency, intensity, duration, plan, and intent), acute psychiatric symptoms (depression, psychosis, agitation, insomnia, hopelessness), recent discharge from psychiatric hospitalization (with the highest risk occurring in the first week post-discharge), acute substance intoxication, interpersonal crisis (breakup, bullying, family conflict, disciplinary action, humiliation), social isolation, sleep disturbance (particularly insomnia), medication non-adherence, and access to lethal means.

Protective Factors

Protective factors include strong family connectedness and support, school connectedness and a sense of belonging, effective coping and problem-solving skills, cultural and religious beliefs that discourage suicide, engaged treatment with a strong therapeutic alliance, restricted access to lethal means, personalized reasons for living, and a social support network.

Risk Assessment

The Clinical Interview

Every adolescent psychiatric evaluation should include suicide risk assessment. The adolescent should be interviewed alone, as many will not disclose suicidal thoughts in front of their parents. Asking about suicide does not increase risk — it opens communication and often provides relief from isolation. A graduated approach works best: starting with general questions about well-being, moving to mood, then hopelessness, then wish to die, then suicidal thoughts, then plan, then intent, then attempts.

Columbia Suicide Severity Rating Scale (C-SSRS)

The C-SSRS is the most widely used standardized suicide assessment tool in both clinical and research settings. It categorizes suicidal ideation by severity on a five-point scale: wish to be dead (1), nonspecific active suicidal thoughts (2), active suicidal ideation with any methods but no plan (3), active suicidal ideation with some intent to act but no specific plan (4), and active suicidal ideation with a specific plan and intent (5). It also assesses suicidal behavior including actual attempts, interrupted attempts, aborted attempts, and preparatory acts. Intensity of ideation is assessed across frequency, duration, controllability, deterrents, and reasons for ideation. The tool is free and available in multiple languages.

ASQ (Ask Suicide-Screening Questions)

The ASQ is a brief four-question screener validated in emergency departments for youth ages 10-24. It takes less than two minutes and has a sensitivity of approximately 97%. Its four questions cover past wish to be dead, past suicidal ideation, current suicidal ideation, and past suicide attempt. A positive screen triggers further assessment but is not a comprehensive evaluation in itself.

Key Assessment Questions

Essential questions include: "Have you ever wished you were dead or wished you could go to sleep and not wake up?" "Have you ever thought about killing yourself?" "Have you ever thought about how you would do it?" (assessing plan). "Have you ever intended to act on those thoughts?" (assessing intent). "Have you ever done anything to try to end your life?" (assessing attempt history). "What has stopped you from acting on these thoughts?" (identifying protective factors and deterrents). "Do you have access to firearms, medications, or other means?"

Risk Stratification

Low risk involves passive ideation without plan, intent, or means access, with strong protective factors and engagement in treatment. Moderate risk involves active ideation with some plan but no intent, ambivalence about living, the presence of some risk factors, and willingness to engage in safety planning. High risk involves active ideation with plan and intent, access to means, a recent attempt, psychotic symptoms, acute intoxication, severe agitation, or unwillingness to engage in safety planning. Risk level guides disposition: low risk supports outpatient treatment with a safety plan; moderate risk may warrant intensive outpatient or crisis stabilization; high risk requires emergency evaluation and likely hospitalization.

Lethal Means Counseling

Rationale

Access to lethal means, especially firearms, is the most modifiable risk factor for suicide completion. Firearms are used in approximately 50% of youth suicides and have a case fatality rate of approximately 85%. The critical insight is that most suicidal crises are temporary — if the person survives, 90% do not go on to die by suicide. Reducing access to means during the acute crisis period literally buys time for the crisis to pass.

Counseling Approach

Clinicians should ask directly about firearms in the home: "Are there any guns in your home or in homes your child visits regularly?" The recommendation is temporary removal of firearms from the home — not just locking, as youth may know combinations or key locations. If removal is not accepted, firearms should be stored locked, unloaded, with ammunition stored separately, or at a friend's home, gun shop, or law enforcement facility. Medication access should also be addressed, with potentially lethal medications (acetaminophen, opioids, psychotropics) secured or removed. Other means should be addressed based on the individual's identified plan. The counseling conversation and the family's response should be documented. Means restriction counseling should occur at every crisis contact, discharge, and follow-up.

Safety Planning

Stanley-Brown Safety Planning Intervention

The Stanley-Brown Safety Planning Intervention is a brief intervention (20-30 minutes) that creates a personalized, written plan for managing suicidal crises. It is evidence-based, associated with reduced suicide attempts and increased treatment engagement. It is collaborative — developed with the patient using their language and preferences — rather than prescribed. It is explicitly not a "no-suicide contract," which has no evidence base and may create a false sense of security.

Six Steps of the Safety Plan

The six steps are: (1) Warning signs — recognizing personal signals that a crisis is developing (specific thoughts, images, moods, situations, or behaviors). (2) Internal coping strategies — things the person can do on their own to distract or soothe, such as exercise, music, breathing, writing, or hobbies, without needing to contact anyone. (3) Social contacts and settings for distraction — people and places that provide positive connection, not necessarily for disclosing the crisis but for reducing isolation. (4) People to contact for help — specific family members, friends, or mentors who can be told about the crisis and asked for support, with names and phone numbers listed. (5) Professional and crisis contacts — the therapist, psychiatrist, 988 Suicide & Crisis Lifeline, and the local emergency department. (6) Making the environment safe — specific means restriction steps such as removing firearms and securing medications.

Implementation

The safety plan should be written on a physical card or entered into the patient's phone so it is accessible during a crisis. It should be reviewed and updated at subsequent visits. Parents and caregivers should be involved in the plan with the adolescent's input and consent. The plan should be practiced before a crisis occurs, and barriers to using it should be identified and troubleshot.

Emergency Evaluation and Disposition

Indications for Emergency Psychiatric Evaluation

Emergency evaluation is indicated for active suicidal ideation with plan and intent, a recent suicide attempt, acute psychosis with suicidal content, acute intoxication with suicidal ideation, self-harm requiring medical attention, inability to maintain safety (when the patient or family cannot follow the safety plan), or when the clinician has concern despite the patient's denial.

Post-Attempt Assessment

Medical stabilization always comes first. The assessment should evaluate lethality of the attempt, degree of planning, expectation of rescue, and the patient's reaction to survival. Factors suggesting higher risk include a high-lethality method, extensive planning, precautions against discovery, regret at surviving, and a persistent wish to die. Psychiatric hospitalization is often indicated after a suicide attempt, particularly when these higher-risk factors are present.

Transition and Follow-Up

The first week after psychiatric discharge is the highest-risk period for suicide, making this transition particularly dangerous. A follow-up appointment should be scheduled within 3-7 days of discharge. Caring contacts — calls or texts from the treatment team during the transition — have been shown to reduce reattempt risk. Family involvement in discharge planning and safety plan review is essential. Continuity of care between emergency, inpatient, and outpatient settings must be ensured.

Clinical Pearls

Asking about suicide does not plant the idea — it opens a critical conversation and relieves the adolescent's isolation. A previous suicide attempt is the single strongest predictor of future suicide death, and attempt history must always be assessed. Safety planning using the Stanley-Brown method is evidence-based, while "no-suicide contracts" are not and should not be used. Firearms account for half of youth suicide deaths, and lethal means counseling should be part of every suicide risk assessment. The first week after psychiatric discharge is the highest-risk period, making bridge appointments and caring contacts essential. The C-SSRS provides a systematic framework for assessing ideation severity and behavioral risk. Risk assessment is not a one-time event — it must be repeated at every clinical contact, especially during transitions of care. LGBTQ+ youth, Black youth, and American Indian/Alaska Native youth are disproportionately affected, and culturally informed assessment is essential. Most suicidal crises are temporary, and means restriction buys the time needed for the crisis to pass.
