用户信息搜寻到信息规避的演化机制研究OA北大核心CHSSCDCSSCICSTPCD

[Purpose/Significance]The public instinctively search for information to alleviate anxiety caused by vari-ous threats.However,unconfirmed and exaggerated information disseminated on the Internet can lead to information over-load,psychological resistance,and cyber-hypochondria,resulting in information avoidance behavior.Therefore,it be-come crucial to understand the mechanism of the shift from information-seeking to information-avoidance behavior when studying user behavior during public health emergencies.[Method/Process]The study reviewed the current status of re-search on users'information-seeking and information-avoidance behaviors,formulated the corresponding hypotheses,con-structed the corresponding theoretical models based on the SOR theory,and empirical studies were conducted using ques-tionnaires and structural equation modeling.[Results/Conclusion]This study utilizes the SOR model to uncover the mech-anisms that drive the shift from information-seeking to information-avoidance behavior in public health emergencies.The results indicate that when users perceive a threat and seek information,they may encounter information overload,psycho-logical resistance,and cyber-hypochondria,leading to information avoidance behavior.These insights contribute to a bet-ter understanding of user information behavior during public health emergencies and offer a practical reference for informa-tion governance.
