Understanding the causes of information anxiety to provide suggestions for reducing users' information anxiety in the academic information searching process and constructing a good academic information environment.【Method/process】 This study employed semi-structured interviews and questionnaire survey methods. First, we revised the Academic Search Information Anxiety Scale through literature research and 8 interview data coding. Then, the academic search process was divided according to the ISP theory, and the questionnaire was compiled by combining the ISP theory and the behavioral process model of online academic in⁃ formation query. Finally, we collected data from 649 academic users.【Result/conclusion】We found that information quality anxiety, information quantity anxiety, information retrieval tool anxiety, information literacy anxiety, information acquisition anxiety, and infor⁃ mation processing anxiety are the six common types of information anxiety among academic users in their search process. In general, users’information acquisition anxiety is much higher than others; the changing pattern of academic search information anxiety would follow the model of increasing first and decreasing then, with the highest degree of collection stage; the type and degree of information anxiety corresponding to each search stage are different, the types of user information anxiety in the initial stage, the selection stage, and the presentation stage are relatively concentrated and single, while the types of information anxiety in the exploratory stage are rel⁃ atively rich.【Innovation/limitation】By constructing a behavioral framework for different stages of academic information seeking, re⁃ search on information anxiety in different stages of the academic information search process from the micro-level
