To construct an evaluation index system of information literacy for public health personnel, and to provide reference for assessing the level of information literacy of public health personnel.

The indicator pool of the indicator system was constructed through the literature research method and combining with the actual work, 19 experts in related fields were invited to conduct two rounds of expert consultation by the Delphi method, so as to determine the final indicators, and the weights of indicators at all levels were determined by the hierarchical analysis method.

The positive coefficients of the two rounds of expert consultation were greater than 90%, and the expert authority coefficients were 0.895 and 0.922. The expert Kendall coordination coefficients were 0.152 and 0.121, respectively P<0.001, and the differences were all statistically significant. Through two rounds of expert consultation, the evaluation index of information literacy of public health personnel constructed by 4 first-level indicators, 15 second-level indicator systems and 38 third-level indicators of information awareness, information knowledge, information competence and information utilization ethics were finalized.

The index system has certain reliability and scientificity, and can provide a reference basis for measuring the information literacy level of public health personnel.
