title: Suicidal behavior and history of substance abuse.
abstract: Substance abuse is frequently associated with suicidal behavior. However, it is unclear to what degree substance abuse in a family member is related to suicide. In the present study, personal and family histories of substance abuse were examined in 716 psychiatric emergency room patients. Suicide attempters, suicide ideators, and nonsuicidal controls were compared across demographic, clinical, and substance abuse variables. Results showed that suicidal patients differed from nonsuicidal controls on many of the dependent variables. Suicidal patients were more likely to be depressed and report a history of previous suicidal tendencies. Also, alcohol and drug abuse occurred more frequently in suicidal patients. Furthermore, a family history of alcohol abuse was reported more often by suicidal than nonsuicidal patients. These patterns of substance abuse in suicidal patients were especially prominent among older subjects. Results are discussed in terms of the implications for identifying psychiatric emergency room patients at risk for suicide.
