The purpose of this study was to review the changes in the art therapy environment due to COVID-19 and art therapist’s perception of the emergence of online art therapy. For this study, 186 art therapy majors who had been working with the clinical art therapy for a year or longer before and after the start of the COVID-19 pandemic participated in an online questionnaire survey in March. 2021. The data collected were processed using the SPSS 25.0 program for descriptive statistical analysis, while the open-ended statements were analyzed for key words using the text-mining technique and for topics using the topic modeling technique. The results of this study can be summed up as follows. First, it was found that most subjects perceived a change in their services due to COVID-19. Second, subjects used online art therapy more frequently due to changes in the external environment, while perceiving online therapy both positively and negatively. Third, the subjects expected that online art therapy would continue even after the end of the COVID-19 pandemic, and therefore, perceived the development of new media and intervention methods for online therapy to be a necessity. Based on these results, the implications and limitations of this study are discussed.
