We conducted a clinical investigation of 80 suicides who met the DSM‐III‐R criteria for schizophrenia. The results using this approach showed no significant difference with those of preceding studies, and general features regarding the phenomenology of suicide among schizophrenics worldwide were recognized. The present study, however, served to underscore the following points: (i) suicide of schizophrenics must be considered a concern at all stages of the disease; (ii) the subjective strength of the will to die may be more important for the committing suicides than the lethality of the methods employed; and (iii) a change in the environment, for example, a hospital admission or discharge, may trigger suicide. A control group of 80 living schizophrenics with no past attempted suicide was then matched to the suicide group with respect to sex and illness duration, in order to identify the predictors of suicide. In a logistic regression analysis, the presence of suicidal ideation, degree of anxiety estimated by positive and negative syndrome scale, and birth order were revealed as predictors of suicide. As to the birth order, the risk is higher in middle children.
