Basic Description: "Multifamily group treatment (MFGT) is an evidence-based intervention for treating persons with severe mental illness, particularly schizophrenia, and their families that integrates psychoeducation and behavioral family therapy in a multiple-family group format. Although multifamily group treatment was first pioneered more than half a century ago by Laqueur (Laqueur et al., 1964), only in the past 15 years has a coherent theoretical model and empirical evidence for its effectiveness been available to clinicians."
