This study was carried out to develop a group art therapy program for teenagers who smoked based on
the integrated change model and to verify its effects on their smoking. The group art therapy program had
goals set according to development steps and proper contents developed based on cognitive, synchronous
and behavioral factors, and reasons of the therapy, and the contents were verified by experts. The subjects
of the study were 37 male students who smoked(22 of experimental group and 15 of control group). They
agreed to this study and they were from D high school in G province. With the exception of 15 research
subjects in a control group, the study offered a Group Art Therapy Program to 22 research subjects in the
experimental group for nine sessions and three follow-up sessions performed between August 2013 and
October 2013. For verifying the effectiveness of the program, knowledge regarding smoking, smoking
decisional balance, self-regulation efficacy in smoking, non-smoking behavior change phases, urine cotinine,
and the amount of CO in breath were measured. The key results were as follows: there were significant
differences in knowledge on smoking in cognitive factor, non-smoking behavior change phases, urine
cotinine, and the amount of CO in breath in behavioral factors, and smoking loss of smoking decisional
balance in synchronous factor between groups. However, there was no significant difference in smoking
gains between groups. There was a significant difference in self-regulation efficacy in smoking between
groups while differences were not consistently maintained. Based on the results above, it was suggested that
a group art therapy using integrated change model is effective in changing behavior. It is expected that if
this group art therapy is applied consistently for schools and adolescents, the health and life quality of
adolescents young people can be positively changed.
