Effectiveness of a Temporal and Sound Space in the Paramedical Management of "Crisis" States of Patients Hospitalized in Psychiatry: Quasi-experimental Study With a Single Arm

The patient will receive specific, individualized paramedical monitoring. The PSYSON device will be presented to the patient during a paramedical interview within 3 days of the inclusion visit, by a pair of investigators composed of a nurse and a paramedic (occupational therapist or psychomotor therapist) or a psychologist.

This interview will help define the patient's personalized sound environment, adapted to moments of anxiety. The pair of investigators plays a key role in creating the playlist, which will constitute the patient's specific sound environment.

The first caregiver investigator will act as a close observer, observing the patient's reactions and psycho-corporal state, which could indicate psychomotor relaxation. The second caregiver investigator will use a tablet or computer provided by the department to enter the patient's choices into the application.

During this interview, the investigator will focus on the patient's emotions and sensory perception. It will begin with the patient's musical request, and to help the patient express his preferences, the investigator can rely on photo language, using "musical atmosphere" cards created for this purpose. These cards highlight a central musical theme, likely to arouse the patient's attention, emotion and certain ideas. Musical instruments can also be made available to observe the patient's musical and rhythmic desires and preferences.
