This article describes the treatment carried out with a six-year-old child who showed a childhood feeding disorder. Intervention has been based in a parents training program supported at home with a token economy. Parents have received specific training to favor the acquisition of abilities that modify the problematic behaviors and consolidate the effects of the intervention with the child. With regard to the parents, results revealed that they had acquired and integrated the learned abilities. This indicates an increased recognition of the understanding to face new problematic situations. With regard to the child, a complete assimilation was observed, according to the established criteria about the new habits, namely, eating alone, grafting food without pounding and an increase in the amount and variety of the grafted food. As a conclusion we could remark the efficiency of the environmental control used by parents in the treatment, and the importance of the token economy in the whole process.
