Of all the kinds of voices people hear in psychosis, command voices are the ones that worry families most. They give instructions — sometimes to do something harmless ("get up", "go for a walk"), sometimes to do something humiliating, sometimes to harm oneself or another person. Their content is what gives them their name, and their content is also why they have been studied more carefully than almost any other category of auditory hallucination.
Command auditory hallucinations are voices that issue instructions; how distressing they are and how often a person obeys them depends much more on the person's relationship with the voice than on the loudness or clarity of the command itself.
How common they are
Among people with schizophrenia who hear voices, roughly one third to one half experience command hallucinations at some point. The figure varies by setting — it is higher in inpatient samples and lower in community samples. A review hosted by the National Library of Medicine (McCarthy-Jones, 2012) summarises this range and notes that within the people who have command voices, only a minority report regular compliance with harmful instructions.
What the voices tell people to do
The clinical literature divides commands into three rough categories:
- Benign or innocuous commands — "drink water", "leave the room", "stand up". These are the most common and the easiest to live with.
- Self-directed harmful commands — instructions to hurt oneself, take an overdose, or attempt suicide.
- Other-directed harmful commands — instructions to hurt someone else.
Most people who hear command voices hear a mix. The same voice that tells someone to take a shower in the morning may, during a worse stretch of illness, tell them something more frightening at night.
What predicts whether someone will act on a command
This is the question clinicians spend the most time on. The research, summarised in clinical psychology reviews and reflected in NICE Clinical Guideline CG178, points to a small number of predictors:
- Beliefs about the voice's identity and power. Believing the voice is omnipotent, malevolent, or supernatural increases compliance risk. Believing the voice is a brain-generated experience that one can resist reduces it.
- Congruence with delusions. When the command lines up with a fixed belief — for example, a voice telling someone to harm a person they already believe is persecuting them — the risk is higher.
- Past compliance. The strongest single predictor of future action is past action.
- Substance use. Intoxication reduces inhibition and worsens judgement.
- Co-occurring depression or hopelessness. Particularly relevant for self-directed commands.
What clinicians do
A good assessment of command voices is not a single question. It usually covers content, frequency, identity attribution, perceived power, the person's beliefs about consequences of compliance and non-compliance, prior actions, current substance use, and current safety. The goal is not to scare the patient but to map the actual risk and the levers that change it.
Treatment usually involves three elements. The first is medication — antipsychotics, with clozapine often considered for command voices that have not responded to two other agents (see our clozapine overview). The second is CBT for psychosis, which works directly on beliefs about voice power and identity. The third is a written safety plan, often updated during inpatient stays and reviewed after discharge.
Coping strategies that people use
People who live with command voices often build a personal toolkit over time:
- Delay. A simple agreement with oneself: "I will not act on a command voice for 24 hours without checking with my therapist." Voices that demand immediate action lose some of their grip when met with a wait.
- Talk back, internally. Many people find it helpful to say, internally, "I hear you, and I am choosing not to do that."
- Reality-test. Phone a trusted person, describe what the voice is saying, and let the conversation interrupt the loop.
- Reduce the power of the voice's identity. If the voice claims to be God, the devil, a deceased relative, or the government, CBTp can dismantle that attribution gradually.
- Track sleep and stress. Command voices often grow louder during bad sleep stretches. Treating sleep is treating voices.
Avatar therapy and command voices
The randomised AVATAR trial published in The Lancet Psychiatry (Craig et al., 2018) showed that creating a digital avatar of the voice and engaging with it under therapist guidance can reduce voice severity, with some patients reporting that the perceived power of the voice dropped specifically. Not all command voices respond, but the approach is a useful option for ones that have not yielded to standard CBTp. See our piece on avatar therapy.
You or your loved one is hearing a voice commanding self-harm or harm to others — call 988 in the US, your local crisis line, or 911. The presence of a harmful command voice is a recognised reason to seek same-day evaluation.
What helps a loved one
If someone you love hears command voices, the most useful things you can do are simple. Ask. Ask what the voice is saying, ask whether they want to act on it, ask what helps when it gets loud. The conversation itself reduces compliance risk for many people because it takes the voice out of the private space where it has the most pull. Our talking to someone in psychosis guide has more on the language to use.
The honest picture
Command voices are frightening when they are first heard, and they remain difficult to live with for many people. But the public assumption that command voices inevitably lead to violence is wrong. With medication, with therapy, with a stable sleep pattern, and with a relationship to a treatment team that treats the voice content as something to talk about rather than something to hide, most people who hear command voices live full, safe lives. The work is real, but so is the path through it.
