Attempted suicide and depression in schizophrenia.

The relationships between symptoms and both prior suicide attempts and current suicidal thinking were examined in a sample of schizophrenics at 2 points in time. Fifty subjects meeting DSM-III criteria for schizophrenia were assessed within 1 week of admission, and 41 were reassessed at a 6-month follow-up. On admission, prior suicide attempts were significantly associated with current depression, female sex, lower education and more frequent hospitalization. The association with depression remained significant at follow-up. In addition, current suicidal thinking was associated with depression at both times but also with negative symptoms at time 1 and delusions and hallucinations at time 2. These findings confirm and strengthen prior reports of an association between depression and attempted suicide.
