Linguistic Characteristics of Suicidal Patients in the ED (Emergency Department)
The purpose of this study is to determine whether patients who have a high risk for serious
suicide behavior will demonstrate a speech pattern that has a relationship to language
patterns found in suicide notes.
suicide behavior will demonstrate a speech pattern that has a relationship to language
patterns found in suicide notes.
In an average week the CCHMC Emergency Department (ED) evaluates 40 patients with suicidal
behavior. Currently, there is no systematic method for assessment of suicide risk in these
patients and often, emergency department staff are required to make judgments about the
disposition of these patients without a full understanding of the patient's risk for another
serious suicide attempt. This pilot project involves experts in child psychiatry, biomedical
informatics, and emergency medicine to collect pilot data for developing a method to
estimate the risk of serious suicidal behavior based on computational linguistics.
