A Mandarin version of the Five Dimensional Altered States of Consciousness (5D-ASC) Rating Scale was developed to improve language accessibility for Mandarin-speaking individuals in psychedelic research. The translation followed the ISPOR Task Force guidelines, involving forward translation by two professionals, review by a native Mandarin speaker, back-translation, and comparison with the original. The scale includes 11 facets such as experience of unity, spiritual experience, and anxiety, and can also be analyzed using the original 5-factor structure. The full survey is provided in the appendix. Further research is needed to evaluate its reliability and validity in Mandarin-speaking populations.
