Mental Health First Aid: How to Help Someone in Crisis
Mental Health First Aid is a structured, evidence-based training program that teaches everyday people how to recognize and respond to mental health and substance use crises before professional help arrives. This page covers what the program involves, how its core action plan works, the situations it's designed to address, and where the boundaries of a layperson's role appropriately end. The stakes are real: the Substance Abuse and Mental Health Services Administration (SAMHSA) estimates that only about half of adults with mental illness receive professional treatment in any given year — which means the other half are likely first encountered by friends, coworkers, or strangers.
Definition and scope
Mental Health First Aid is a public education program developed in Australia in 2000 by Betty Kitchener and Anthony Jorm, then adapted for the United States by the National Council for Mental Wellbeing starting in 2008. It is not a clinical credential. A certified Mental Health First Aider cannot diagnose, prescribe, or provide therapy — but that's precisely the point. The program fills the gap between recognizing that something is wrong and getting someone to the crisis intervention and emergency mental health resources that can actually treat it.
The standard certification course runs 8 hours for adults and covers mental health challenges including depression and mood disorders, anxiety disorders, psychotic disorders, and substance use. A separate Youth Mental Health First Aid course, also 8 hours, is tailored to adults who work with adolescents — teachers, coaches, youth workers — and addresses the developmental context of mental health in children and adolescents.
As of 2023, the National Council for Mental Wellbeing reported that more than 3 million people in the United States had been trained through the program (National Council for Mental Wellbeing, 2023).
How it works
The program's action plan goes by the acronym ALGEE, which functions as a decision scaffold — not a rigid script — for responding to someone in distress.
- Assess for risk of suicide or harm. This step asks the first aider to directly and calmly inquire about suicidal thoughts. Contrary to a persistent myth, research cited by the Zero Suicide Institute indicates that asking about suicide does not increase risk.
- Listen nonjudgmentally. Active, non-reactive listening is the mechanism of trust-building. The first aider isn't solving — they're staying present.
- Give reassurance and information. Normalizing the person's experience, without minimizing it, and sharing that effective help exists.
- Encourage appropriate professional help. This includes connecting the person with a therapist, primary care physician, or mental health hotlines and crisis lines depending on severity.
- Encourage self-help and other support strategies. Peer support, community resources, and coping tools — including community mental health centers or low-cost and free mental health resources — that don't require a clinical appointment.
The ALGEE framework doesn't demand that steps be executed in strict sequence. Someone in acute panic won't pause politely for an orderly assessment. The structure exists to prevent paralysis — to give the first aider something to hold onto when the situation is messy, which it usually is.
Common scenarios
Mental Health First Aid training addresses three broad categories of situation, each requiring a different calibration of urgency and approach.
Crisis situations are those involving imminent risk: a person expressing active suicidal intent, a panic attack severe enough to cause physical symptoms, a psychotic episode with disorganized behavior, or severe intoxication. These warrant direct engagement with the ALGEE steps and, where appropriate, contact with emergency services. The suicide prevention resource network is the relevant escalation pathway here.
Non-crisis but urgent situations include someone showing signs of a depressive episode that has lasted more than 2 weeks, a person disclosing recent trauma, or a colleague whose behavior has visibly changed over time in ways consistent with emerging PTSD and trauma-related disorders. These don't require a 911 call — they require a calm, informed conversation and a warm handoff to professional support.
Subthreshold or early warning situations involve subtle signs: withdrawal from social contact, changes in sleep or appetite, irritability that seems out of proportion. Early intervention in mental health research consistently shows that acting on early warning signs — even informally — reduces the severity and duration of episodes. A first aider in this context is essentially a concerned human being with a slightly better vocabulary than average.
Decision boundaries
The hardest question in Mental Health First Aid isn't what to do — it's when to step back. The program draws a clear line: a first aider's role ends where clinical responsibility begins.
Contrast the two modes this way. A Mental Health First Aider is trained to recognize and refer. A licensed mental health professional is trained to diagnose and treat. These are not interchangeable, and attempting to cross that boundary — offering an amateur diagnosis, recommending specific medications, advising someone to discontinue prescribed treatment — causes harm even when motivated by genuine care.
The first aider should escalate to emergency services (911 or the 988 Suicide and Crisis Lifeline) when someone is in immediate danger of harming themselves or others, is unable to care for themselves due to a mental state, or explicitly requests emergency help. The 988 Suicide and Crisis Lifeline, established by SAMHSA, is the national routing system for mental health emergencies and connects callers to trained counselors, not first responders — which matters for people who are frightened of police involvement.
Supporting a loved one with mental illness over the long term is a different discipline than responding to an acute crisis — and finding a mental health provider for ongoing care is where the first aider's role formally concludes and professional treatment begins. The national mental health resource index provides a structured overview of where both emergency and ongoing support can be located.
