The purposes of this study were to develop abstract expression-centered art therapy program and
investigate the effects of the program on the symptoms of internalization of students with disabilities in
inclusive classrooms. Based on the results of TRF, ten students with disabilities as well as internalizing
symptoms in inclusive classrooms were recruited. This participants were placed by random assignment
of balancing group sampling into the control group and the experimental group. An abstract
expression-centered art therapy program was carried out 2 sessions a week, total 20, for over 60 minutes
each. Qualitative analyses and quantitative were used to examine the effects of program. The change results
of each session and attitude were used for qualitative analysis while the results of pre-TRF and post-TRF
were used for quantitative analysis. The major findings of the study were as the followings. The major
findings of the study were as the followings. First, participants in the experimental group showed
internalizing symptoms in change results of each session and attitude significantly lower than before, while
participants in the control group showed no differences in internalizing symptoms. Second, participants in
the experimental group showed internalizing scores in TRF significantly lower than before, while
participants in the control group showed no differences in internalizing symptoms. Third, participants in the
experimental group showed anxiety/depression scores in TRF subtest significantly lower than before, while
participants in the control group showed no differences in anxiety/depression scores. Fourth, participants in
the experimental group showed withdrawn/depression scores in TRF subtest significantly lower than before,
while participants in the control group showed no differences in withdrawn/depression scores. Based on the
results, abstract expression-centered art therapy program can alleviate internalizing symptoms of students
with disabilities in inclusive classrooms and help them adjust school life and have good friendships. And
several suggestions were made for the future study.
