Delusions of control are among the most distinctive experiences in psychosis. Unlike persecutory or referential delusions, which are about beliefs about the world, delusions of control involve a disturbance in the basic sense of being the agent of one's own body and mind. A person may feel that their arm is being moved by an outside force, that an emotion has been "placed" in them, or that an action they performed was not really their own.
A delusion of control — sometimes called a passivity phenomenon — is the experience that one's own actions, feelings, or impulses are being caused or directed by an external agent rather than one's own self.
The Schneiderian background
The German psychiatrist Kurt Schneider in the 1950s identified a list of "first-rank symptoms" he believed were particularly suggestive of schizophrenia. Several of them are forms of delusion of control:
- Made actions — the sense that one's movements are being performed by an outside agent
- Made impulses — sudden urges that feel imposed
- Made feelings — emotions that arrive as if installed
- Somatic passivity — bodily sensations attributed to an outside force
Modern diagnostic systems no longer treat first-rank symptoms as pathognomonic — they appear in other conditions and not all schizophrenia cases include them — but they remain a useful clinical vocabulary. The DSM-5-TR recognises these as types of bizarre delusions.
What it can feel like
People who have lived through delusions of control describe experiences such as:
- "My hand reached for the cup but it was not me deciding to reach"
- "I felt sudden rage that wasn't mine — it was put into me"
- "The government's signal made my legs walk down a particular street"
- "There were rays going through my body adjusting how I stood"
The experience is not metaphorical. It is the literal felt sense that the boundary between self and not-self has been crossed.
Why this happens — current thinking
Researchers think delusions of control reflect a disruption in what neuroscientists call predictive motor signalling or the sense of agency. When you move your arm, your brain normally generates a "copy" of the motor command — a so-called efference copy — that lets you predict and recognise the movement as your own. In schizophrenia, this signalling appears disturbed, so movements and impulses generated by one's own brain do not feel self-generated. The brain then constructs an explanation for the foreign-feeling movement, and that explanation becomes the delusion.
Differential diagnosis
Other conditions can produce similar experiences and need to be ruled out:
- Dissociative disorders — where actions feel unreal or detached but are not attributed to outside agents
- Substance-induced psychosis — particularly stimulants and dissociatives
- Frontal-lobe stroke or tumour — alien limb syndrome can mimic delusions of control without other psychotic symptoms
- Severe OCD — intrusive thoughts can feel "not mine" but are usually recognised as one's own thinking
Risk and safety
Delusions of control can drive dangerous behaviour because the person may feel compelled by an outside force and may not feel responsible for their actions. Made impulses to harm self or others should be treated as urgent.
A loved one describes being "made" to do dangerous things, hearing commands they feel they must obey, or feeling that an outside force is moving their body to harm. Call 988 in the US, your local emergency number, or take them to an emergency department.
Treatment
Antipsychotic medication is the first-line treatment, and delusions of control typically reduce in intensity along with other positive symptoms over weeks of treatment. Severe or persistent first-rank symptoms in someone who has not responded to two adequate trials of antipsychotics should raise the question of clozapine. CBTp can help people make sense of these experiences, reduce distress, and rebuild a sense of agency over time.
What helps in the moment
For someone who is currently experiencing delusions of control, the goal is grounding and safety, not argument:
- Use a calm, low voice and short sentences
- Acknowledge the distress without endorsing the content ("That sounds frightening")
- Help orient — name, place, time, who is in the room
- Offer a familiar physical anchor — holding a cup, sitting in a known chair
- Contact the person's clinician or crisis team if symptoms are severe
