ABSTRACT ? Background and Objectives: Even if verbal fluency deficits have been described in Schizophrenia, error pattern in this test has not been analyzed in detail in the literature.The pattern analysis of such errors could contribute to the understanding of the factors that influence poor task performance in schizophrenia. In this study we analyzed the intrusion and perseveration errors in verbal fluency tasks in patients with chronic schizophrenia. Methods: 87 patients diagnosed with Chronic Schizophrenia and 87 healthy controls wereincluded in this investigation and were assessed with four Phonological and Semantic Verbal Fluency tasks.Results: The results of this study showed that at least half of schizophrenic patients produced perseverative errors on verbal fluency and about made intrusion errors. The severity of negative symptoms, the severity of Formal Thought Disorder and pharmacological varia - bles were significant moderators to errors in Verbal Fluency performance.Conclusions: Errors in Verbal Fluency can be explained by the interaction of differentvariables in patients with schizophrenia. Schizophrenia is a psychological pathology with great phenomenological complexity and its particularities can only be explained by the consideration of the multiple factors involved in its manifestation
