BACKGROUND The purpose of this study was to develop and test the psychometric properties of a questionnaire that assesses preschool teachers' self‐efficacy in providing asthma care. METHODS A total of 407 teachers from 54 preschools in Taiwan participated in the study by completing the asthma management self‐efficacy scale. We assessed validity of the scale through expert opinion, exploratory factor analysis, and confirmatory factor analysis. The reliability of the scale was assessed using Cronbach's alpha. RESULTS A 10‐items questionnaire was developed to assess self‐efficacy concerning asthma treatment. On the basis of explorative factor analysis, 2 major factors emerged from the 10 self‐efficacy items that together explained 61.68% of the total variance in teachers' self‐efficacy with regard to asthma care. We named these factors “prevention of an asthma episode” and “the treatment of an asthma exacerbation.” Confirmatory factor analysis revealed that the 2‐factor model provided the best goodness‐of‐fit. CONCLUSIONS This scale could provide health professionals with useful information concerning preschool teachers' self‐efficacy with respect to the management of asthma in the preschool setting.
