Abstract

Homicide is the most serious and costly criminal offense and better forensic and criminological understanding of homicidal ideation as a potential psychobehavioral precursor to homicidal conduct is critical. Using data from the 2016 Nationwide Emergency Department Sample (NEDS) from the Healthcare Cost and Utilization Project (HCUP) distributed by the Agency for Healthcare Research and Quality (AHRQ), we found 64,910 cases of homicidal ideation among a sample of 25.6 + million—a prevalence of 0.25%. Numerous conditions conferred increased substantially the likelihood of homicidal ideation including antisocial personality disorder (2406%), schizoaffective disorder (1821%), borderline personality disorder (1557%), paranoid personality disorder (1,504%), schizophrenia (1,143%), obsessive–compulsive personality disorder (921%), brief psychotic disorder (771%), unspecified psychosis (737%), avoidant personality disorder (596%), and schizoid personality disorder (571%), delusional disorder (546%), and other psychotic disorder (504%). Homicidal ideation is comorbid with serious psychiatric and behavioral problems and has important implications for offender typologies and homicidality.
