Cross-national reliability, concurrent validity, and stability of a brief method for assessing expressed emotion

The Five-Minute Speech Sample (FMSS; Magana et al., 1986) is a brief method designed to assess the "expressed emotion" (EE) status of a respondent. The FMSS-EE rating is derived from statements made by a patient's key relative during a 5-minute monologue, with codes similar to those used in the original EE rating system (e.g., criticism and emotional overinvolvement). Rating is done from the audiotape and takes about 15-30 minutes. The article reports on the results of a cross-national study carried out in Germany using the FMSS with a sample of 60 relatives of schizophrenic patients. Results indicated that (1) German investigators could readily learn the system and could achieve a high degree of interrater reliability; (2) the association with the original index of EE, the Camberwell Family Interview, was comparable to that found by Magana et al.; and (3) the method yields very stable data over a 4-5 week retest period.
