[Expressed emotion: past, present, future]

Expressed Emotion (EE) proved to be the best single predictor of relapse in schizophrenia in 1972. Since then, studies on EE were oriented in three directions: Replication of the original study in different countries, improvement of the methodology and clinical applications. The analysis of different key studies shows that EE is a powerful predictor factor, although it is influenced by other variables such as culture.
