This study was aimed to disclose repressed feelings of the adolescents from the low socio-economic oackgrounds and the broken home through the group art therapy, to share them with group members, and to confront them in order to sympathize with each other. And self expression through art material was to recognize one’s feelings, to communicate by oneself and to have a insight into oneself so as to help self-understanding and self-growth. At the view point of the developing stages the adolescents is somewhat defiant, self-assertive and aggressive. At a program using art as a therapy material art seemed to play a role of a buffering zone to alleviate those feelings. The objectives of this study were focused only to the adolescents from the low socio-economic backgrounds and the broken home they seemed to get many of psychological trauma, individual repressed feelings, and frustration during a growth period. Drawing and painting made them express and disclose their such feelings, resulting in coordinating them and having an excellent insight into them by oneself this gradual process means to be effective in therapy. The occurrence of those problems were concrete!y not only due to excessive expression of one\'s feelings, self-showing off or public winning of fair recognition. but also in the op.posite way due to self-misunderstanding by extraordinary self-cutting down. Therefore, while showed withdrawal and/or repressed self-expression and self-disclosure before, visitors was gradually gettìng better by showîng a clear self-expressìon, an obvious self- assertion and an enhanced abìlity of public expression in front of a group through group art therapy to let them show self-disclosure with aggressive behavior excessively exaggerated expression of feelings and self-showing off, visitors tried to adjust self-feelings and to adapt self into a group. They could seemingly feel sympathy and cohesion with group members, and especially experience catharsis by clisclosing and emitting such self-feelings. They could have a time to enjoy their self through perception and catharsis of self-feelings. This study was limited by a small size of this group (7 participants), a short penod of this program, one-sided composition of only girls, and not enough disclosure of each participants on the diverse problems including sexual problem. At the end of this program, moreover, the beginning of school made them reduce their cohesion, finally loose this group. It is necessary to keep continuous guidance and financial support, because they all were the adolescents from the low socio-economic backgrounds and the broken home, and had absurd structure of their family as well.
