Abstract:
Objective:To translate the Papua New Guinea Vision-Specific Quality of Life Questionnaire (PNG-VS QoL) into Chinese and test its reliability and validity.Methods:The Chinese version of PNG-VS QoL was developed through translation, back translation, cross-cultural adaption, and pre-survey. From July to September 2023, convenience sampling was used to select visually impaired patients admitted to Henan Provincial People's Hospital as participants. The Chinese version of PNG-VS QoL was used to investigate and test the reliability and validity of the scale.Results:A total of 440 questionnaires were distributed, and after excluding invalid questionnaires that were illogical or had multiple choices, 435 valid questionnaires were collected, with an effective response rate of 98.86%. Exploratory factor analysis showed that the Chinese version of PNG-VS QoL extracted two common factors with a cumulative variance contribution rate of 73.651%. The Cronbach's α coefficient of the Chinese version of PNG-VS QoL was 0.934, and the Cronbach's α coefficients of the two dimensions were 0.934 and 0.925, respectively. The content validity index ( CVI) at the item level ranged from 0.800 to 1.000, and the CVI/ Ave at the scale level was 0.910. Confirmatory factor analysis showed that χ 2/ df was 1.533, TLI was 0.985, CFI was 0.992, and RMSEA was 0.043. Conclusions:The Chinese version of PNG-VS QoL has good psychometric properties and is suitable for evaluating the quality of life of visually impaired patients.
