Linguistic performance in schizophrenia: a comparison of acute and chronic patients
P Thomas, K King, WI Fraser and RE Kendell
Manchester Royal Infirmary.
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.
