ABSTRACT
Objective:To translate the University of Rhode Island Change Assessment of voice scale（URICA-Voice） into Chinese and test its reliability and validity. Methods:The URICA-Voice scale was converted into Chinese by literal translation, cultural adjustment, expert consultation, pre-investigation, and back translation. Convenience sampling was used to recruit patients at four speech therapy centers from February to May 2022. Then the Chinese version of the scale was distributed to them, and the reliability and validity of the scale were tested after data collection. Cronbach ɑ was used to evaluate the reliability. The critical ratio method and Pearson correlation coefficient were used for item analysis. Item-level content validity, scale-level content validity, and confirmatory factor analysis were used to test the validity of the scale. Results:A total of 247 valid questionnaires were collected. ①Item analysis: the critical ratios between a high-score and low-score groups of 32 items were all statistically significant（P<0.01） and all the critical ratios were above 3.00. The Pearson correlation between 32 items and the total score was significant（P<0.01）. ②Validity analysis: I-CVI=1.00, S-CVI/Ave=1.00, χ²/df=2.30, RMSEA=0.07. Except for item 9 and 23, the standardized factor loading coefficients of other items were all above 0.50. AVE of the four dimensions of the scale was all above 0.50, and the combined reliability of the four dimensions was all above 0.70. The correlation coefficients between dimensions were less than the square root of the AVE of the dimension itself. ③Reliability analysis: the Cronbach ɑ of the whole scale was 0.94, and the Cronbach ɑ of the four dimensions were 0.88, 0.92, 0.94, and 0.88 respectively. Conclusion:The Chinese version of URICA-Voice has good reliability and validity, and can be used as a specific measurement tool for evaluating the compliance of voice training in China.
