A pilot study was conducted to detect suicide risk in adolescents and adults presenting to an Emergency Department (ED) in the Midwest, as well as to test the reliability and validity of the 4-item Risk of Suicide Questionnaire (RSQ) developed by Horowitz, et al. (2001). Participants consisted of a convenience sample of 104 ED patients ranging in age from 12 to 82 regardless of chief complaint or psychiatric history. The RSQ was verbally administered to 39 adolescents (age 12 to 24) and 65 adults (over 25). Demographic data, chief complaint, and discharge diagnosis were also obtained. Psychometric analysis demonstrated an adequate degree of reliability and criterion related validity. Results support a reduced 2-item form of the RSQ to determine imminent risk of suicide.
