  Purpose

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.

Detailed Description:

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.

  • English is spoken as the primary language in the home

Exclusion Criteria for Suicidal Subjects:

  • Level of consciousness precludes consent and research assessments
  • Unable to assent because of severe mental retardation or incapacitating psychosis

Exclusion Criteria for Non-Suicidal Subjects:

  • Any current or past suicide attempts
