T he risk of suicide in schizophrenia is high; it is estimated that 10%-13% of all persons suffering from schizophrenia commit suicide (1). Suicide rates vary among mortality studies, between 147 and 750 per 100,000 persons with schizophrenia per year (2-6). The rate is consistently higher among men than women, but some studies have shown a higher standardized mortality ratio for women (7-9). The prevalence of schizophrenia among unselected persons who committed suicide has varied from 2% to 12% (10-16).Many studies of clinical characteristics of suicide victims with schizophrenia have been compromised by the relatively small numbers of subjects and thus inadequate representation of women for comparisons of the sexes, by the heterogenous diagnostic criteria used, by the frequent selection of the suicide population from hospitals, and by data based only on patient records.Seven studies (17-23) have so far investigated completed suicides among groups of 15 or more suicide victims with DSM-III or DSM-III-R schizophrenia. In these studies young adult age, male sex, and mean illness duration under 10 years have characterized suicide victims with schizophrenia. Some studies, however, have shown an increased rate of suicide mortality over the span of the illness (24). Comorbid depressive symptoms, alcoholism, previous suicide attempts, and communication of suicidal intent have been associated with suicide risk (15,17,(19)(20)(21). These, as well as some physical disorders, have also been found to be associated with suicide in the general population (25). Mental disorders, suicide method, and history of previous suicide attempts have been found to vary with age and sex
