Language profiles were developed for schizophrenic, manic and nonpsychotic control subjects from the analysis of free speech samples. The profiles comprised syntactic variables reflecting the complexity, integrity and fluency of spoken language. Linguistic differences between the 3 diagnostic groups enabled accurate (95%) classification by discriminant function analysis. The results suggest an important role for language analysis in psychiatric diagnosis.
