My experience with multi family groups - In this article the author tells about having discovered the GPMF existence while he was looking for a work methodology to compete with the outbreak of the negative therapeutic reaction of psychotic patients, at the moment of the re-entry in their families. The patients were previously cured with good results in a Therapeutic CommunityFor the author, as probably for every other operator that experiences it, the GPMF symbolizes the result of a long and unconscious research work, at which a meaning can be attributed only subsequently, carried on in both, the external world, by knowledge and learning different therapeutic techniques, and mainly, the internal world, through his own maturation process. A process whose aim is to achieve the awareness of the possibility to deal with psychosis being on the same footing and not, as generally happens, from an hopeless position. Following García Badaracco’s suggestions, the author tries to demonstrate that the GPMF is one of the most interesting ways through which the heritage of psychoanalytical and psychotherapeutic knowledge, mainly utilized for the study and the treatment of neurotic patients, may be used with psychotic patients, assuming the use of this knowledge through the psychoanalysis multifamily group experience. Considering that, the GPMF represents the privileged place where learning to deal with and defuse the unbearable mechanisms that produce and maintain psychosis is possible.
