Objective To establish clinical pharmacists' competency behavior questionnaire and confirm the validity of the competency model of clinical pharmacists. Methods On the basis of previous model research, clinical pharmacists' behavior questionnaire combining the Likert scaling and literature retrieval method was established,and the competency model was verified by method of exploring factor analysis and " construct validity" and confirmatory factor analysis. Results Questionnaire included 47 characteristic projects and ten basic information projects.Exploratory factor analysis extracted 5 factors,whose content was in accordance with the model of competency characteristics.Cronbach 's alpha coefficients of each factor project were (0.510-0.961).Discrimination validity of the behavior questionnaire was good.T-test results showed good statistical difference between the outstanding group and the normal group, and the empirical validity of the model was better. Confirmatory factor analysis of structural equation model was acceptable,and the CIF was 0. 825. Conclusion The competency model is valid and can distinguish clinical pharmacists with excellent performance.
