After mentioning the basic assumptions underlying traditional models of family therapy which have raised serious criticism, new models are reviewed which overcome these limitations. The new models on family intervention share two characteristics. They view relatives as natural allies in the process of rehabilitation of the patient and rely on highly structured therapeutic strategies. Four such strategies are briefly described and the evidence supporting their efficiency reviewed: Goldstein's crisis orieted family therapy, the psychosocial intervention package developed by Leff and cols., Falloon's behavioral family therapy and the family psychoeducation pro gram by Anderson and cols. Their efficiency is analyzed in terms of the observed decrement in relapse rates as well as other benefits for both patient and relatives. The general principies underliying these therapeutic approaches are underlined. Finally, an analysis is attemted regarding some observed defficiencies, which further studies should help solve in order to arrive at more solid condusions on the efficiency of diese new therapeutic approaches.
