title: Defect symptoms and abnormal involuntary movement in schizophrenia.
abstract: Tardive dyskinesia (TD), a possible marker of the defect state of schizophrenia, was studied along with defect symptoms in 55 neuroleptic-treated chronic schizophrenic patients. Our cross-sectional data failed to replicate earlier findings of increased defect symptoms in TD patients (n = 14), except for more severe paucity of speech content when compared with non-TD patients (n = 41). Methodological issues that may account for some of the current and previously reported findings are discussed.
