Expressed emotion from the five-minute speech sample and relapse of out-patients with schizophrenia.

We investigated the relationship between 9-month relapse of 40 outpatients with schizophrenia and expressed emotion (EE) evaluated by the Five-Minute Speech Sample (FMSS). The results of this study suggest that the FMSS is suitable for use as a convenient instrument to measure EE, although it shows more false-positive results. Therefore borderline EE of the FMSS might have to be regarded as high EE.
