the social skills of children with mental retardation. For the purpose, this
researcher provided mentally retarded children with 5 sessions of baseline,
and 12 sessions of art therapy, 60 minutes per one session over 4 months. In
this case, the researcher utilized AB type of the Single System Design. The
measurement is the Social Skills Scale which was restructured to contain 15
question items in total, with 5 for each of 3 sub-areas. The rating system
was created by Gresham and Elliot(1990). The SINGWIN Program was
utilized to determine changes in social skills. And the pre-and post-projective
drawing tests were analytically compared in terms of social skills. The
findings of the study as follows. First, it was found that art therapy had
significant effects on the social skills that children with mental retardation
had. Second, the projective drawing tests found that mentally retarded
children changed in the social skills more positively after than before art
therapy. Third, it was found that art therapy made children with mental
retardation show more and more positive changes in the of social skills as
art activity sessions where those children participated became in more and
more progress.
