Impact of Sound Shower Music Diffusion on Family Anxiety in Intensive Care Unit Waiting Room

When a family member or a relative visits a patient in the intensive care unit for the first time, the investigators may ask to participate in the MUSICALITY research protocol. After randomization, relative will be included in either the control group or the music intervention group. Just before the intervention (music therapy or not), the investigators will ask them to complete the questionnaire State-Trait Anxiety Inventory-Y (STAI-Y, also called Spielberger questionnaire) and a numerical scale of experience. The relative will then wait in the waiting room with or without music during 20 to 30 minutes. At the end of the waiting period, the same questionnaire STAI-Y and the same numerical scale of experience will be completed again by the relative. For the music intervention group, the investigators will ask them also to complete a satisfaction questionnaire regarding their music listening experience. The relative will then be received by the medical and paramedical team in charge of the patient for health informations. A numerical scale of overall satisfaction will be completed by each group, at the end of the protocol intervention.
