Cronbach α coefficient of internal consistency was 0.777, and Cronbach α coefficient of three common factors were 0.849, 0.824 and 0.752 respectively. Six experts scored the questionnaire, the CVI of each item were 0.83-1.00, and the average CVI was 0.968. The correlation coefficient between each item and the total score were 0.322-0.648 ( P<0.01).
