Suicide in psychiatric patients. A prospective study of 67 cases without initial signs of severe depression or alcoholism

All cases from the county, who were subjected to post-mortem examination at the Department of Forensic Medicine, University of Lund with a diagnosis of suicide during 1949-1984, were compared with the inpatient register at the Department of Psychiatry, University Hospital, Lund during 1949-1969. During these years all patients were rated at discharge with a multidimensional schedule. All patients with initial ratings of severe depression/melancholia and alcoholism were analyzed separately and excluded from the present sample. The ratings of the suicide cases were compared with those of 8,046 other inpatients. There were 67 suicide cases, 36 men and 31 women. The suicide cases had higher frequencies of the item easily led/dependent/immature personality (34% versus 18%) and of attempted suicides (19% versus 8%). There were no differences in ratings of symptoms as slight depression and anxiety or of situational factors. Attempted suicide was related to suicides early in the course, while easily led/dependent/immature was not so related. At the time of the suicide there was a higher frequency of never married and a lower frequency of married subjects in the present series compared with suicides in severe depression/melancholia and alcoholism.
