Objective To evaluate the reliability and validity of the instrument of clinical applicability of guidelines (version 2.0). Methods The experts of domestic medical institutions were investigated by questionnaire, and the instrument of clinical applicability of guidelines (version 2.0) were evaluated the guidelines for the diagnosis and treatment of tinea mantis and tinea pedis (revised edition 2017) and the guidelines for the diagnosis and treatment of cerebral hemorrhage in China (2019). Using Cronbach's α coefficient and Spearman-Brown coefficient to evaluate the inherent reliability and split-half reliability. The content validity was evaluated by calculating the content validity index of the item level and the adjusted Kappa value. The correlation coefficient between each item and the dimension and the hypothesis test were used to evaluate the convergent and discriminant validity. The structural validity was evaluated by using structural equation model to evaluate the structural validity of the tool. Results The Cronbach's α coefficient and Spearman-Brown coefficient of the instrument of clinical applicability of guidelines (version 2.0) were both greater than 0.7, the content validity index (S-CVI/Ave) were more than 0.8, the success rates of convergent were 100%, and the success rates of discriminant validity calibration were 100% and 96%. In the second-order confirmatory factor analysis model, the χ2/ df were less than 3, the fitting index (CFI), the goodness of fit index (GFI) and the adjustment goodness of fit index (AGFI) were all greater than 0.9. The root mean square residual (RMR) were all less than 0.05, and approximate error root mean square (RMSEA) were less than 0.09. The P value of RESEA hypothesis test were more than 0.05. Conclusion The instrument of clinical applicability of guidelines (version 2.0) has good reliability and validity, which can be further verified in practical application in the future.
