This study explored the association between psychosocial variables and
symptoms among patients with schizophrenia-spectrum disorders who hav
e attempted suicide and those who have not attempted suicide. Of 336 p
atients with a DSM-III-R diagnosis of schizophrenia or schizoaffective
disorder who were consecutively evaluated at a university-affiliated
clinical research center, 98, or 29.2 percent, reported one or more su
icide attempts. Compared with patients who had not attempted suicide,
patients who had made an attempt had a greater number of lifetime depr
essive episodes, an earlier age of onset of their illness, and an earl
ier age at first hospitalization.
