Differences between depressed patients with and without suicidal ideation were examined, focusing on anger, aggression, and hostility. The Adult Suicide Ideation Questionnaire was used to compare 42 outpatients with major depression in relationship to measures of anger, aggression, hostility, cynicism, life events, and depression. There were no differences on measures of anger, aggression, hostility, and on most measures of severity of depression, but the suicidal group demonstrated more evidence of cynicism. Suicidal ideation is associated with cynicism but is unrelated to measures of hostility, anger, or aggression or to severity of depression in outpatients.
