Features associated with suicide attempts in recurrent major depression.

Sixty-seven individuals with recurrent major depression and a history of suicide attempts are compared with 163 individuals with recurrent major depression and no history of suicide attempts. The groups are contrasted on demographic features, clinical course, severity of depression, co-morbidity, and acute symptom profiles. Patients with a history of attempts are distinguished from non-attempters by suicidal ideation, marital isolation, neurovegetative signs, feelings of failure, and co-morbid alcoholism or bipolar II disorder. Logistic regression analysis using a model which included a portion of the significant variables correctly classified 77% of the cases. These findings are discussed with reference to prediction of suicide attempts in individuals with major affective disorder.
