Mindfulness-based Virtual Reality Intervention

Symptom burden was assessed using the Chinese version of the M. D. Anderson Symptom Inventory (MDASI-C),39 which is a self-report scale consisting of two domains. The first domain is named "core symptom severity items" and has 13 symptoms. Each symptom is rated on an 11-point scale (0-10) to indicate the presence and severity of the symptom, with 0 indicating "not present" and 10 indicating "as bad as you can imagine." Each symptom is rated based on the severity of the symptom, at its worst, in the last 24 h. The second domain is named "six symptoms interference items" and includes ratings of how much symptoms interfered with different aspects of the survivor's life in the last 24 h. The interference items are also rated on a scale of 0-10, with 0 indicating "did not interfere" and 10 indicating "interfered completely." A score of 0-3 indicated a mild level, 4-6 indicated a moderate level, and 7-10 indicated a severe level of symptom severity or interference.
