This study is for applying group art therapy to children who have difficulties in adjustment to school life due to
their ADHD prone in order for the children to be declined of problematic behaviors and to experience positive
adjustment to school life. The purpose of this study is to investigate effects of group art therapy on declination in
problematic behaviors and enhancement of adjustment to school life of ADHD prone children. The subjects of this
study were ten male ADHD prone children between 11 and 12 years old, and they were divided into the
experiment group(five) and the control group (the rest five). The K-ADHDDS was used as a tool of diagnose, and
the Abbreviated Conners Teacher Rating Scale, the BBRS, the School Adjustment Scale, the CFD, and the KSD were
used as the research tools. The research was conducted between September 11 and November 27, 2009, and
10-session program was presented once a week, each session with 90 minutes. The group art therapy program was
progressed with Introduction, Activity(feeling, thinking, drawing, making, and speaking), and Completion. The changes
affecting the problematic behaviors and adjustment to school life of the subjects both in the experiment group and in
the control group were compared quantitatively and qualitatively. The results of this study are as follows. First,
statistically significant results were shown in the changes in pre- and post-test scores of the Abbreviated Conners
Teacher Rating Scale, in order to investigate the quantitative effects of the group art therapy on the problematic
behaviors of ADHD prone children. Second, statistically significant results were shown in the problematic behaviors
from the changes in pre- and post-test scores of the BBRS, in order to investigate the quantitative effects of the
group art therapy on the problematic behaviors of ADHD prone children. Third, statistically significant results were
shown in the adjustment to school life from the changes in pre- and post-test scores of the School Adjustment Scale,
in order to investigate the quantitative effects of the group art therapy on the adjustment to school life of ADHD
prone children. Fourth, the comparison between pre- and post- mode of changes in behaviors of the children by
behavioral observation for identifying the qualitative effects of the group art therapy showed that tendencies of
problematic behaviors were generally declined and positive behaviors appeared. Fifth, the comparison between the preand
post- CFD of each child for identifying the qualitative effects of the group art therapy on the problematic
behaviors of ADHD prone children showed that there were positive changes in the problematic behaviors. Sixth, the
comparison between the pre- and post- KSD of each child for identifying the qualitative effects of the group art
therapy on the adjustment to school life of ADHD prone children showed that there were positive changes in the
adjustment to school life. Conclusively, the group art therapy had positive effects on declination in problematic
behaviors and enhancement of adjustment to school life of ADHD prone children.
