For the clinical component:

Describe the young people hospitalised in residential care at the FSEF, in particular through vulnerability factors and their psychosocial repercussions (school level, repetition, intensity of symptoms, irritability, nervousness, substance use (cannabis, alcohol, tobacco), social relationships, family relationships, well-being, level of health literacy, learning disorders)) and to compare them with young people from the general school population.

For the epidemiological aspect:

To study the construct validity of the EnCLASS questions aiming to characterize handicap situations in the general school population in both a population in situation of psychic handicap and of somatic handicap.

Residential care in psychiatry in France, although recommended by the HAS and widely implemented, have been little evaluated In France, the residential care of the FSEF called "soins-études" have long been recognized as contributors to psychosocial rehabilitation. They hospitalize young people with mental and physical disabilities. They allow the continuation of hospital care associated with the resumption of schooling and the implementation of a training project integrated into the individualized care plan. Each year, around 1 500 young people are admitted to full-time hospitalization for "soins-études" in psychiatry or medicine (follow-up care and rehabilitation) within the FSEF. They benefit from comprehensive care, adapted to their needs, including care, maintenance or resumption of schooling and social reintegration in a peer group. A recent review of the literature showed that the provision of "soins-études" in psychiatry allows clinical improvement in nearly two-thirds of between more than 5 years after admissionit, and the resumption of schooling and a training project. The young people admitted at the FSEF generally have been receiving care for more than 3 years for chronic psychiatric disorders. Despite frequent school delays or periods of dropping out of school, a large majority of them had a school activity during the care.

However, it appears from this review that the characteristics of the young people received have never been compared with those of students in a traditional education course. Characterizing this population meets a need, as well as a strong institutional demand (FSEF, funders and national education).

The EnCLASS-FSEF survey will be rolled out with the national EnCLASS methodology in all the annexes of the National Education schools integrated into the 13 FSEF care-study clinics (therefore on the total population in care-studies of the FSEF educated in secondary school) - making it possible to describe and compare the patients treated in care studies with the general school population.

Inclusion Criteria:

• Student cared for in college and high school studies in the 13 clinics of the FSEF,
• From 11 years old,
• Non-opposition of the student to his participation in the study and to the use of his data (and of their parents for minor students).

Exclusion Criteria:

• Student opposition to participating in the study (or their parents for underage students).

All young people hospitalized in care-study in the 13 clinics in the FSEF (i.e. around 1,500) over the period from March to June 2022.
