The goal of this systematic revision of literature is to critically analyze articles on group play therapy for children besides emphasizing promising findings. Articles based upon on-line data were raised from 2000 to 2011. 14 articles were identified. We found only 11 articles about group play therapy. Group play therapy showed to be efficient in the treatment of language difficulty, learning difficulty, internalizing problems and aggressiveness. Children with light mental deficiency and suffering from racial prejudice also benefit. Besides, they treat victims of earthquake and home violence. We can find researches both qualitative and quantitative with two concurrent approaches and a theoretical study. Of the six researched types of group play therapy, the most frequent was the child-centered group play therapy modality. We find it still necessary to understand the process of group learning linked to psychotherapeutic results. This means analyzing the conflicts and also the moments of integration in the group. As promising findings, we identified the application of group play therapy in schools and the importance of having a socio-political view of childhood. Implications for the research: more qualitative researches to understand the meanings which children and professionals give to the process of changing in behavior. Besides that, we propose experimental group play therapy with different psychological diagnosis.
