Abstract:
Objective:Inhaler satisfaction is an important factor affecting inhaler adherence and the efficacy of inhalers in chronic airway diseases.Using a scientific and effective method to assess patients'satisfaction with inhalers is of great significance for improving clinical outcomes.The Feeling of Satisfaction with Inhaler-10(FSI-10)is specifically designed to assess patients'inhaler satisfaction in chronic airway diseases,but the application research on this scale is not available in China.This study aims to evaluate the reliability and validity of the Chinese version of FSI-10,describe the current status of inhaler satisfaction and discuss the associated variables in Chinese patients with chronic airway disease. Methods:Based on the English version of FSI-10,items of the Chinese version of FSI-10 were determined after forward-backward translation and cultural adaption.Totally,322 patients with chronic obstructive pulmonary disease(COPD)and asthma were enrolled from the Second Xiangya Hospital of Central South University from June to October 2022.We collected associated clinical variables and inhaler satisfaction using the Chinese version of FSI-10.The content validity of the scale was expressed by content validity index(CVI)and the construct validity was analyzed by exploratory factor analysis(EFA).The reliability of the scale was expressed by Cronbach's α coefficient,the split-half reliability and test-retest reliability.A multivariate logistic regression was conducted to examine variables related to inhaler satisfaction. Results:The reliability and validity analysis showed that the CVI was 0.983.One factor was extracted from the Chinese version of FSI-10 and the cumulative variance contribution rate was 73.114%.The Cronbach's α of the scale was 0.913,the Guttman's half-reliability coefficient was 0.905,and the test-retest reliability was 0.727(P<0.001).In addition,the total score of the scale for patients was 38.92±4.26 points and the proportion of high satisfaction(the score of FSI-10≥40)in patients with COPD was significantly lower than that in asthma patients(71.3%vs 87.9%,P<0.01).Older age(age≥70 years)was a risk factor of lower inhaler satisfaction and asthma diagnosis was a protective factor. Conclusion:The Chinese version of FSI-10 has good reliability and validity in patients with COPD and asthma,which may be further promoted and applied in patients with chronic airway disease in China.Doctors should regularly evaluate the inhaler satisfaction of patients with chronic airway diseases,especially for those elder or with severe symptoms and a long course of illness.
