Our aim was to test the findings of a study which claimed that, if the syntactic structure of schizophrenic speech were subjected to a detailed linguistic analysis, clear differences would be demonstrated between schizophrenic, manic and control populations. It was confirmed that schizophrenics do have less syntactically complex speech which contains more errors. Using linguistic variables in a discriminant function analysis, it was possible to predict diagnoses correctly in 79% of cases.
我们的目的是验证一项研究的结果。该研究称，如果对精神分裂症患者的言语句法结构进行详细的语言分析，就会发现精神分裂症患者、躁狂症患者和对照组人群之间存在明显差异。研究证实，精神分裂症患者的言语句法复杂程度确实较低，错误较多。在判别函数分析中使用语言变量，可以在79%的病例中正确预测诊断结果。
