Abstract

The lifetime risk of suicide in patients with schizophrenia is estimated to be 4.9-13%. While there are many known risk factors for suicide in schizophrenia, the relationship between cognitive function and suicide risk is unclear, particularly in non-Caucasian populations. In our cross-sectional study, we administered the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) to 316 Han Chinese chronic inpatients with schizophrenia and compared the performance of those who had attempted suicide (n=25) to non-attempters (n=291). The lifetime suicide attempt data were collected from medical records and interviews with patients and their family members. We found a lifetime suicide attempt rate of 7.9%. Suicide attempters were more likely to be single, but showed no significant differences in other demographic factors such as age, gender, or living arrangements. Contrary to our hypothesis, there was no significant relationship between performance on the RBANS test and lifetime risk of suicide attempts in Han Chinese inpatients with schizophrenia. The literature remains mixed on this topic. Culturally influenced differences in suicidal behavior may have affected the outcome of this study and further investigation of this topic is necessary.
