PRODUCTION OF AFFIRMATIVE, NEGATIVE AND INTERROGATIVE SENTENCES IN SCHIZOPHRENIA
Language disorder is one of the most significant symptom domains which characterize Schizophrenia Disorder. The aim of the present study considering these language problems is to find out the number of the affirmative, negative and interrogative sentences on schizophrenia patients’ spontaneous speech and reveal whether their depression, doubts and sceptical behaviours affect their speech. Fifty patients with schizophrenia diagnosed according to DSM-IV criteria were included into the study and compared to fifty healthy subjects matched for age, sex and education level with the patients participated in the study. The subjects’ speech was evaluated by using subject-based narration and free verbal narration tests. As a result of the statistical and linguistic analyses, significant differences were found between schizophrenic patients’ and healthy subjects’ speech in terms of between affirmative, negative and interrogative sentence use. The results indicate that the patients' excessive use of negative and interrogative sentences is related to their feature of attributing negatively to the events and emotions they experience.
