The purpose of this study was to identify the comprehensive contents of art therapy studies related to PTSD both domestically and abroad and to organize the latest research trends from a macroscopic point of view. Frequency analysis and keyword network analysis were conducted on 87 art therapy studies on PTSD among academic journals and doctoral dissertations published from 2007 to 2018. Via frequency analysis, we examined the number of study publications, research subjects, trauma types, study methods and characteristics of art therapy intervention. Subsequently, keyword network analysis was conducted to investigate the relationships among keywords. While more than half of the domestic studies concentrated on women, there was a shortage of mixed male-female studies especially compared to abroad. Furthermore, there was no study of subjects who indirectly experienced trauma cases. types of research methods tended to be limited to experimental and case studies. In light of these results, it is essential to expand research subjects. when the keywords and keyword networks were analyzed, the subjects of domestic research are mainly focused on certain traumatic emotions, such as depression and anxiety. Overall, the scope of research themes should be widened and various research types should be explored via dealing with the methodological aspects of study outcomes according to processes and procedures such as research frame and protocol development research.
