Mélisses Garden: Effect on Anxious State in Adult Patients Hospitalized in Psychiatry

Study Overview
=================
Brief Summary
-----------------
Each hospitalization leads to stress and anxiety. This is particularly true in psychiatry, because of decompensation. That is why therapeutic treatments are delivered quickly to treat these symptoms and to allow a better relationship with patients. This relationship patients-nursing staff called therapeutic alliance is needed in psychiatry. Moreover, other treatments added to the therapeutic ones are used, like mediation, to increase the patients' state of health. These last years, numerous studies were based on hortitherapy or care-gardens. It consists in the use of plants with a medical staff (for example nurses). A lot demonstrated the efficacy of the care-gardens, but most of them showed methodological weaknesses. That is why the investigators would like to perform a randomized study, controlled, and they aim to demonstrate the efficacy of hortitherapy on anxiety in patients allowed in adult psychiatry for at least 4 weeks.

Detailed Description
-----------------
Each hospitalization leads to stress and anxiety. This is particularly true in psychiatry, because of decompensation that increases anxiety and fear. That is why therapeutic treatments are delivered quickly to treat these symptoms and to allow a better relationship with patients. This relationship patients-nursing staff called therapeutic alliance is needed in psychiatry. Moreover, other treatments added to the therapeutic ones are used, like mediation, to increase the patients' state of health. These last years, numerous studies were based on hortitherapy or care-gardens. It consists in the use of plants with a medical staff (for example nurses). A lot demonstrated the efficacy of the care-gardens, but most of them showed methodological weaknesses : no control group, no randomization, few patients. Furthermore, these studies were not performed with feared patients hospitalized in psychiatry. That is why the investigators would like to perform a randomized study, controlled, and they aim to demonstrate the efficacy of hortitherapy on anxiety in patients allowed in adult psychiatry for at least 4 weeks. This study will be performed on 190 patients who will be included in one of these groups: Control group : only usual care Hortitherapy group : 2 hortitherapy sessions/week during 4 weeks, added at the usual care. Anxiety will be evaluated with HAD-A scale that is a brief questionnaire (2 at 6 minutes). HAD-A is very sensitive at the modifications and allows to follow the evolution of the anxiety. This scale is easy to use by the nursing staff and shows an excellent reliability, by the way really adapted to this study. On another hand researchers will also focus on the effects on the therapeutic alliance and the persistence of the effects at week 8.
