A clinical study was conducted of 80 suicides who met the DSM-III-R criteria for schizophrenia. The results showed no significant differences from other studies. However, this study underscored the following points: suicide must be considered a concern at all stages of schizophrenia; the subjective strength of the will to die may be more important than the lethality of the methods used; & change in the environment, e.g. a hospital admission or discharge, may trigger suicide. In a logistic regression analysis of the 80 suicides & 80 controls, the presence of suicidal ideation, degree of anxiety, & birth order were revealed as predictors of suicide. Risk was higher in middle children. (24 refs.)
