计算机辅助分析了急性精神分裂症患者（50名）、慢性精神分裂症患者（27名）和正常受试者（50名）的自由言论样本，对三组人的语言特征进行了比较。在语言的复杂性、完整性（错误）和流畅性方面，慢性患者一直是受损最严重的，急性患者的表现不如正常患者，但比慢性患者好。人口差异只能解释语言差异的一小部分。来自社区的慢性精神分裂症患者和来自长期病房的慢性精神分裂症患者的比较表明，他们糟糕的语言表现在某种程度上与疾病过程有关，而与机构无关。研究人员考虑了对这些结果的三种可能的解释，特别是低语言复杂性、阴性症状和不良结果在某种程度上相关的可能性。
A computer-assisted analysis of samples of free speech from acute schizophrenics (n = 50), chronic schizophrenics (n = 27) and normal subjects (n = 50) enabled a comparison of the linguistic profiles of the three groups. The chronic group consistently emerged as the most impaired, on measures of complexity, integrity (error) and fluency of speech, with the acute patients performing less well than normal speakers but better than chronic patients. Demographic differences could account for only a small number of the linguistic differences. A comparison of chronic schizophrenics from the community and those from long-stay wards suggested that their poor linguistic performance was in some way related to the illness process and not to institutionalisation. Three possible explanations for these results were considered, particularly the possibility that low complexity of speech, negative symptoms and poor outcome are in some way related.
