Objective In this study, we aim to translate the original English version of the velopharyngeal insufficiency effects on life outcomes instrument (VELO) into Chinese and test the psychometric properties of VELO among eligible Chinese patients with velopharyngeal insufficiency (VPI).Methods The original English version of VELO was translated, back-translated, and adapted among different cultures. Based on the standard procedures of the International Quality of Life Assessment (IQoLA) project, VELO was established for self-assessment by patients and assessment by caregivers. The reliability and validity of our translated VELO were assessed in Chinese patients with VPI and their caregivers.Results A total of 366 questionnaires were completed, 211 of whichwere completed by patients and 155 by caregivers. In addition, 362 (98.91%) valid questionnaires were collected, comprising 109 questionnaires from the patients in the experimental group, 99 from the patients in the control group, 66 from the caregivers in the experimental group, and 88 from the caregivers in the control group. The cronbach’s α of VELO for a patient with VPI was 0.937, and that of a caregiver was 0.950. Meanwhile, the Guttman split-half reliability coefficient of a patient with VPI was 0.908, and that of a caregiver was 0.887. After the content was validated, the items had intermediate or high correlation with corresponding domains. The patients with VPI and control patients were effectively discriminated through VELO, indicating that the results reached the IQoLA standard. The same result was obtained in the caregivers.Conclusion The translated Chinese version of VELO has acceptable reliability and validity. These psychometric properties provide theoretical evidence for further use of VELO in Chinese patients with VPI.
