[Inpatient rehabilitation of chronic schizophrenic patients with a behavior therapy token reinforcement program].

The efficacy of a token economy system was assessed in a study involving 76 chronic schizophrenics who were inpatients during a treatment period of four years. The interrelations between therapeutic success on the one hand, and socio-economic as well as course of disease-related factors on the other were studied, including psychopathology and the efficacy of token economy.
