The prediction of relapse of schizophrenic patients using emotional data obtained from their relatives.

The capacity of anxiety and hostility outward scores derived from the content analysis of 5-minute speech samples from the relatives of patients to predict relapse or nonrelapse was tested in three distinct groups of schizophrenic patients. Significantly correct predictions were made which compared favorably to the predictive capacity of ratings obtained by means of the Camberwell Family Interview. The latter requires 1 to 2 hours to administer and about 1 hour to score, whereas the former method requires a tape-recorded 5-minute speech sample and up to 0.5 hour to score.
