This randomized controlled trial aims to evaluate the effects of virtual reality-based art therapy and physical art therapy on anxiety, psychological well-being, and sleep quality in patients with colorectal cancer receiving outpatient chemotherapy. A total of 78 patients will be randomly assigned to three groups: a virtual reality art therapy group, a physical art therapy group, and a control group. Participants in the intervention groups will receive art therapy sessions every two weeks for eight weeks (four sessions in total). Anxiety, psychological well-being, and sleep quality will be assessed using validated scales before the intervention and after the fourth session. The findings are expected to contribute to the development of non-pharmacological supportive care interventions for oncology patients.
