This report compares estimates of suicidality (i.e., serious thoughts of suicide, suicide plans, suicide attempts, and receipt of medical care for a suicide attempt) generated from the 2008-2012 National Survey on Drug Use and Health (NSDUH) with estimates of similar measures acquired from other national data sources: National Comorbidity Survey Replication (NCS-R), the Youth Risk Behavior Survey (YRBS), the National Hospital Discharge Survey (NHDS), and the Nationwide Inpatient Sample (NIS). Results are shown by gender, race/ethnicity, age, and year data collected.
