Most chronic psychiatric disorders begin before the age of 18. In the most severe cases, prolonged hospitalization is essential, but this ultimately leads to harmful school dropout and social exclusion. "Care-study" hospitalizations offer comprehensive psychiatric, educational, and social care to prevent this. However, these programs have been largely under-evaluated ; only one limited and very old study has looked at the perspective of the young people concerned, and none at all has looked at their parents. Today, however, PREMS (Patient-Reported Experience Measures), which assess how users experience care (satisfaction, subjective and objective experiences, relationships with caregivers), are important indicators for improving care systems. the investigators therefore wish to gather young people's expectations regarding healthcare and education, as well as their opinions and those of their parents on their experiences in the current context, in order to evaluate and improve these systems by better meeting the expectations and needs of users.
