Language content and schizophrenia in acute phase Turkish patients

The purpose of this study was to replicate and extend, in a Turkish sample, previous investigations of speech content in English-speaking schizophrenics. Computer content analytic procedures, which quantify thematic emphases in the subjects' free speech, have been shown to differentiate schizophrenic patients from other acutely ill psychiatric patients and from normal controls. We repeated the speech sampling procedure with hospitalized psychiatric patients in Turkey, and analyzed their responses using content analysis procedures with a translation of the dictionary or language classification system used in the original studies of English-speaking patients in the United States. Eighty subjects were included in the study: 20 schizophrenics, 20 depressives, 20 manics and 20 healthy controls. There were ten females and ten males in each group. After being diagnosed separately by two clinicians using the Turkish version of the Structured Clinical Interview for DSM-III-R (SCID), each subject's free speech was tape-recorded in a standardized session. The speech content of Turkish patients with schizophrenia exhibited considerable similarity to that previously observed in American subjects, but there were certain dissimilarities that appeared to reflect the impact of culture on the manifestations of the schizophrenic disorder. The phenomenological differences between the three psychiatric syndromes compared were also reflected in the results of the content analysis. The most dissimilar syndromes were mania and depression whereas the most similar were mania and schizophrenia. The particular word categories emphasized by specific groups also appeared to be consistent with the effects of their psychiatric disorders.(ABSTRACT TRUNCATED AT 250 WORDS)
