Cross-cultural Adaptation of the Chinese Version of QoLAF-Q (Quality of Life in Patients With Anal Fistula Questionnaire) ：A Multi-center Study

When the investigators conduct cross-cultural adaptation to verify the applicability of QoLAF-Q in China, the investigators also compare it with the cross-cultural adaptation results of other language versions of this scale. While verifying the reliability and practicality of the Chinese adaptation results of QoLAF-Q, the investigators also explore its differences, which helps Chinese doctors better master the methods and techniques of quality of life assessment, pay more attention to the physical and mental health of patients, improve the quality of life and satisfaction of patients, and provide a reference for the development of more scientific, effective, and practical scales.
