abstract="OBJECTIVE: The aim of this study was to investigate whether suicide attempters had higher IQ, better executive functioning, or were more impulsive as measured by neuropsychological tests than non-attempters in a group of patients with schizophrenia spectrum disorders. METHOD: One hundred seventy-four patients with schizophrenia spectrum disorders were assessed with a clinical interview for diagnosis, suicidality, symptoms and function, and underwent an extensive neurocognitive test battery. RESULTS: There were no statistically significant differences in any neurocognitive domains between lifetime suicide attempters and non-attempters, or between patients with different rates of suicide attempts. Currently suicidal patients were significantly more impulsive (had poorer inhibitory control) than currently non-suicidal patients, but this difference was mediated by positive psychotic symptoms. CONCLUSION: The findings indicate that among patients with schizophrenia spectrum disorders, there are no significant differences in IQ or neurocognitive functioning between suicide attempters and non-attempters.<p /> <p>Language: en</p>",
