Abstract： [Purpose/significance] This paper analyzed and summarized the existing studies abroad, aiming at clarifying the concepts, theories, tools and methods, and influencing factors of scientific literacy in the context of citizen science, and provided guidance for the development of relevant studies in China. [Method/process] We identify the current scientific literacy based on citizen science of related theoretical results by the method of the theme of content analysis.[Result/conclusion] The results show that the concepts of scientific literacy in citizen science context can be divided into "general literacy " and "specific literacy". The measurement indicators of scientific literacy mainly focus on the dimensions of knowledge, understanding and attitude, and the methods involve qualitative, quantitative and mixed methods. In order to improve the sensitivity of measurement, the theories in pedagogy, behavioral science and information science are introduced to develop measurement tools. The balance between scientific goals and educational goals is a dynamic development process, and the influence path of scientific literacy has not yet formed a systematic framework. The literature review enlightens that the development of scientific literacy in the context of citizen science in China can concentrate on the participants, measurement tools, influencing factors and the external environment.

Abstract： [Purpose/significance] Recently, health information has become prevalent on the Internet. The extensive information volume and heterogeneity in information quality increased the probability of encountering conflicting information in users’ health information seeking. However, it has been insufficiently explored how conflicting health information may impact users. This study departs from the relationship between information seeking and uncertainty reduction, as indicated by many classic information behavior theories. We raised a research question of whether the hypothesized relationship still stands in conflicting health information contexts. [Method/process] By employing the experimental approach and one-way analysis of variance (ANOVA), we examine the effects of conflicting health information on individuals regarding knowledge states, confusion, and health beliefs. [Result/conclusion] The results suggested that conflicting health information blurred knowledge states, increased confusion, and decreased health belief. Thus, we inferred that uncertainty increased when they encountered conflicting health information. Based on the results, several theoretical and practical implications were discussed.

Abstract： [Purpose/significance] Online surrogate health information seeking is an everyday life information practice mode based on interpersonal cooperation. It is of great significance of deeply understanding the information behaviors to explore the influencing factors and mechanisms of this behavior based on the classical theories. [Method/process] Based on the health belief model and social support theory, this paper constructed the influencing factors model of surrogate health information seeking and put forward 12 research hypotheses. 475 valid data were collected through questionnaire survey and analyzed by SmartPLS. [Result/conclusion] The results show that empathy, information support intention, perceived severity and perceived benefits have positive impact on online surrogate health information seeking intention (OSHISI), while perceived barriers have a negative impact on OSHISI. Perceived susceptibility and self-efficacy have no direct relationship with OSHISI. The mediating effect analysis showed that the relationship between perceived susceptibility and OSHISI is completely mediated by empathy. Empathy plays a partial mediating role in the relationship between perceived severity and OSHISI. The relationship between self-efficacy and OSHISI is partially mediated by information support intention. The results of this study provide a reference for further motivating, managing and intervening online surrogate health information seeking practices.
