A multicenter clinical survey was conducted using the initial questionnaire formed. Sixty-six questionnaires were issued. After the questionnaire was recalled, the five methods of project response theory, discrete trend analysis, factor analysis, correlation coefficient and Cronbach’s Alpha Coefficient Entries are filtered. The results of screening, the final scale a total of 56 entries, divided into physiological functions, psychological function, social support, subjective feelings in four areas, a total of 9 aspects.
