Background: Delusion of control, including thought insertion, occurs in 20% of patients with schizophrenia. However little is known of its psychopathology, and studies involving patients are scarce. Aims: To explore the subjective experience of patients with delusion of control and to propose a psychopathological explanation based on empirical evidence. Methods: Qualitative exploratory study of 7 patients (6 with schizophrenia and 1 with schizophreniform disorder). A phenomenologically-oriented semi-structured interview was used. Results: Delusion of control is not an isolated and pure symptom; it is always immersed in the context of a persecutory delusion and other psychiatric symptoms. The patient experiences partial control, i.e. the control is never complete. In all cases, it is possible to trace the history of the narrative formation of delusion of control from its origins in persecutory delusions and other concomitant symptoms. Conclusions: The delusion of control is a narrative resulting from the joint presence of a persecutory delusion and other psychiatric symptoms. For the patient, the delusion of control is the narrative of the elaborate expression of the meaning of the anomalous experience. Delusion of control is a narrative variety of persecutory delusion.
