The purpose of this study was to identify the effects of telehealth group art therapy on the quality of life, cancer coping, and post-traumatic growth of cancer survivors. Telehealth group art therapy was conducted for 1st, 2nd, and 3rd group between 2021 and 2022 during the COVID-19 pandemic. The subjects of the study were adult cancer survivors aged 18 or older, recruited in three waves. The participants were divided into two groups, an experimental group of 20 survivors who participated in telehealth group art therapy and a control group of 18 survivors who did not take any action. The experimental group in the study engaged in telehealth group art therapy once a week for 90 minutes, totaling 10 sessions, using the Zoom program, a video conferencing platform. Both groups underwent pre- and post-scale tests to determine the effect of telehealth group art therapy. As a result of the study, the post-difference analysis of telehealth group art therapy showed significant effects on the quality of life, cancer coping, and post-traumatic growth, unlike the control group. These findings showed that the telehealth group art therapy for cancer survivors fully reflected the therapeutic factors of art therapy and could be applied in the event of an isolated subject or a new infectious disease such as COVID-19 due to weak immunity. Based on these research results, the significance and limitations of this study were discussed.
