Abstract: [Purpose/Significance] With the development of politics and economy, the public's attention to health information has significantly increased. The public's behavior of searching, sharing, avoiding, and collaborating on health information has attracted widespread attention. In the ubiquitous information environment, the impact of information behavior interactivity is also gradually increasing. The conflict and control of interpersonal information behavior are gradually receiving attention. Among various types of interpersonal relationships, conflicts and controls in family health information behavior are more prominent, with intergenerational conflicts and controls being the most typical. Therefore, taking the intergenerational relationship between parents and children as the starting point, this paper explores the causes of intergenerational conflict health information behavior and its mechanism in the implementation/response process of social control. An analysis of intergenerational conflict health information behavior can provide assistance for the public to better handle intergenerational relationships, improve the efficiency of parent-child health information communication, and provide certain reference for research on interpersonal health information behavior based on interactivity. [Method/Process] On the basis of literature review, centering on the interactive characteristics of intergenerational health information behavior, from the perspective of information conflict and social control, and taking the whole process of health information behavior interaction of different subjects as the underlying logic, this paper puts forward five core issues. A questionnaire was designed based on the core questions. From the perspective of parents as implementers of control behavior, we investigated the attitudes and reactions of children towards family conflict health information behavior. From the perspective of children as implementers of control behavior, we investigated parents' attitudes and responses to conflict health information behavior in their families. [Results/Conclusions] It is found that there are differences among family members in the information acquisition situation, information source selection and judgment in the preparatory process of implementing/responding to social control. In the process of implementing/responding to social control, family members will choose different ways to implement/respond to different social control, such as information sharing, information evaluation, information avoidance, and information utilization. After implementing/coping with social control, compared with children, parents' sharing behavior and control behavior are more likely to be affected by children's attitudes. Intergenerational conflict health information behavior plays an important role in the implementation/response process of social control. Based on the analysis, the analysis model of intergenerational conflict health information behavior was constructed, and the causes of intergenerational conflict health information behavior and its mechanism in the implementation of social control were explained to some extent. Interpersonal communication is an important means to alleviate intergenerational health information conflict. In the future, qualitative research methods can be used to supplement and improve the model, and more in-depth research and exploration can be conducted around issues such as intergenerational conflict health information behavior and intergenerational information communication.
