Abstract
Videotaped assessments of standardized interviews were used to ensure blindness in relation to a clinical trial of multifaceted programmes of management in patients with treatment-resistant schizophrenia. The technique, although laborious, was feasible in all patients studied and offered advantages in relation not only to blindness but also to assessing the nature of psychopathological changes in patients with schizophrenic deficit syndrome of severe degree. The method is likely to be useful in further studies assessing the possible advantages of newer antipsychotic drugs.
