Abstract: Objective To evaluate the reliability and validity of Chinese version of Morisky medication adherence scale（MMAS-8） in asthmatic children，and to study the related factors affecting medication compliance in asthmatic children.Methods The children with asthma admitted to the Respiratory Clinic of Yancheng Children's Hospital from January 2021 to June 2022 were selected for a questionnaire survey. Cronbach α was used for internal consistency reliability evaluation，and Kaiser Meyer Olkin and Bartlett were used for validity testing. Multivariate ordinal Logistic regression was also used to analyze the independent factors associated with medication compliance in asthmatic children. Results A total of 130 children with asthma who met the requirements were screened and 126 valid questionnaires were returned. The Cronbach α value of the Chinese version of the MMAS-8 questionnaire was 0.724，the KMO value was 0.741，and the χ2 of Bartlett 's spherical test was 248.19（P＜0.01）.High medication compliance was significantly associated with ≤ 1 episode in the past six months，guardian being a parent，high awareness of asthma drugs and diseases，and disease duration＞1 year.  Conclusion The Chinese version of Morisky has good reliability and validity in children with asthma，and poor medication compliance in children in the survey is correlated with guardians，number of attacks in the past six months，awareness of asthma drugs and diseases，and course of disease.
