Objective To develop the Patient Reported Outcomes Scale After Early Lung Cancer Surgery, and to test its reliability and validity. Methods The scale was developed through literature review, semi-structured interviews and Delphi expert consultation method.Then the scale was used in a survey involving 300 patients after early lung cancer surgery for reliability and validity testing. Results After two rounds of Delphi expert consultation, a total of 54 items were formed for the 4-domain scale:the physiological domain had 4 dimensions of chest symptoms, gastrointestinal symptoms, systemic symptoms, and independence; the psychological domain had 3 dimensions of anxiety, depression, and pessimism; the social domain had 2 dimensions of social support and social adaptation; the treatment domain had 4 dimensions of effectiveness, satisfaction, compliance, and adverse reactions of treatment.Exploratory factor analysis extracted 13 common factors with eigenvalues >1, with a cumulative variance contribution rate of 86.026%.The item-level content validity index （CVI ） ranged from 0.800 to 1.000, and the scale-level S-CVI/Ave stood at 0.940.The Cronbach′s α coefficient of the scale was 0.927, and the split-half reliability coefficient was 0.735. Conclusion The Patient Reported Outcomes Scale After Early Lung Cancer Surgery enjoys good reliability and validity, which can be used as an objective tool to evaluate the changes of patient reported outcomes after early lung cancer surgery, and provide references for post-operative symptom management for surgery of such kind.
