The investigator will investigate the use of non-invasive wearable device physiological measures. this in order to predict aggression, and violence outburst in children under 12 years old, which are admitted at an inpatient psychiatric ward. also, the investigator will try to do a characterization of those physiological measures in the prediction of aggression and violence outbursts.
the investigator will include patients under the age of 13 with various mental disorders admitted to our inpatient psychiatry ward at 'Edmond and Lily Safra' Children's Hospital, Sheba Medical Centre, Tel Hashomer, Ramat Gan, Israel during 2024.
the investigator will exclude patients that were hospitalized but did not want to participate, or couldn't participate due to increased sensorial sensitive to the device. the investigator will exclude patients with no violence outburst or aggressive attitude that were hospitalized at our inpatient psychiatric ward during 2024. additional, patients who suffers dermatological illnesses and might show allergic reactions to the device material on their wrist will be excluded.
