Introduction:
The aim of this study was to compare schizophrenic patients with and without a suicide attempt history in terms of sociodemographic and clinical features and cognitive functions and to determine the predictive factors for suicide attempt history.
Methods:
In this study, we assessed and compared 70 patients with schizophrenia, 27 patients with a suicide attempt history, and 43 patients without a suicide attempt history. The cognitive functions of patients were assessed by the Stroop test, Wisconsin Card Sorting Test (WCST), and Rey Auditory Verbal Learning Test. In order to evaluate clinical symptoms, the Positive and Negative Syndrome Scale (PANSS) and Calgary Depression Scale for Schizophrenia (CDSS) were used.
Results:
In this study, the number of hospitalizations, PANSS general psychopathology subscale score, CDSS total score, suicide item score, and WCST total number of responses (WCST1) were significantly higher among the patients with a suicide attempt history. The WCST1 and CDSS total scores were predicted using the suicide attempt history.
Conclusion:
Revealing the factors related to suicidal behavior in patients with schizophrenia contributes to the prevention of suicide. Studies with long-term follow-up and with a larger sample group are required for the investigation of relationship suicide, cognitive impairment, which is one of the core symptoms of schizophrenia, and depression.
