Abstract: Objective To test the reliability and validity of the Chinese version of Quality-of-Life Questionnaire for Mechanically Ventilated Patients (QOL-MV). Methods The English version of QOL-MV was revised and translated into Chinese version. The reliability and validity of the Chinese version of QOL-MV was tested in 120 mechanically ventilated patients. Results The Cronbachαcoefficient of the Chinese QOL-MV was 0.904. The item-level content validity index of Chinese QOL-MV were 0.86-1.00 and the scale-level content validity index of Chinese QOL-MV was 0.92. Two factors were extracted by factor analysis and the cumulated variance was 80.18%. The dimensional factor loading of each item was greater than 0.565. The correlation coefficient between the score of Chinese QOL-MV and the Euroqol Group′s 5-domain 3 Level Questionnaire (EQ-5D) and Richards Campbell Sleep Questionnaire (RCSQ) was 0.947 and 0.561 respectively (P<0.01). Conclusions The Chinese version of QOL-MV has been proved to be reliable and valid.It can be used to measure the quality-of-life for mechanically ventilated patients.
