Abstract

Objective: To assess the relation between positive and negative symptoms of schizophrenia with maintenance of attention in these patients. Method: Thirty-two patients with schizophrenia (15 acute and 17 chronic patients) and 32 normal individuals aged 19-51 years were selected. The two groups were matched on the basis of age, gender and education, and were assessed by the Continuous Performance Test (CPT). In order to study the multivariate correlation between positive and negative symptoms of schizophrenia, and CPT variables, the Scale for the Assessment of Negative Symptoms (SANS) and the Scale for the Assessment of Positive Symptoms (SAPS) were administered.Results: The results indicated that patients with schizophrenia had significantly poorer performance in comparison to normal individuals in all CPT variables (correct response, omission and commission). Regression analysis showed that the delusion component of positive symptoms, positively predicted correct response variable and negatively predicted the omission and commission variables. The affective flattening component of negative symptoms predicted correct response variable of CPT negatively and the omission and commission variables positively. Conclusion: These results show the deficit of maintenance of attention in patients with schizophrenia and support the validity of negative–positive syndrome discrimination in these patients.
