Abstract
Background. Although poor language test performance has been documented in schizophrenia, its
relationship to formal thought disorder remains unclear.Method. Forty schizophrenic patients were administered eight language tests and, under blind
conditions, rated for formal thought disorder. Measures of general intellectual function were also
obtained.Results. Performance on all language tests was significantly correlated with the general intellectual
measures. Three language test scores also showed significant correlations with formal thought
disorder scores. Multiple regression and analysis of intellectually preserved patients suggested
particular associations of formal thought disorder with semantic comprehension and picture
description.Conclusions. General intellectual impairment is an important determinant of poor language test
performance in schizophrenia, but presence of formal thought disorder may also contribute. A
higher-order semantic deficit may be particularly relevant to both linguistic impairment and formal
thought disorder.
