中文摘要:
      目的:掌握基于微博平台的乳腺癌防治健康信息的传播特征,并识别高影响力用户。方法:以225名微博认证用户及其关注关系为基础,采用社会网络分析法,从宏观、中观、微观3个维度分析乳腺癌防治健康信息传播网络及各用户特征。结果:传播网络的小世界效应不明显且整体密度较低。19.11%的用户活跃度较高且具有一定影响力,已形成多个规模较大的小团体且团体间成员重复。结论:用户整体活跃度稍弱,用户间联系交流频率稍低。各用户尤其是孤立成员需加强互动沟通,提高联系紧密度并缩短信息传播距离。非核心区用户需提高活跃度并增强信息传播能力,各用户应加入多个小团体,加强跨团体信息交换并扩大信息传播范围。位于关键节点的用户需确保所发布的信息科学、权威,并提高信息更新频率,保障微博健康信息的质量。
英文摘要:
      Objective To study the characteristics of breast cancer prevention and treatment information dissemination based on microBlog platform and identify the users with a high influencing power. Methods The characteristics of breast cancer prevention and treatment information dissemination network and its 225 microBlog-certified users were analyzed by social network analysis at macrodimension, mesodimesion and microdimension levels. Results The small world effect of breast cancer prevention and treatment information network dissemination was not significant and its overall density was low. The activity level was rather high in 19.11% of breast cancer prevention and treatment information dissemination network users with a certain influencing power, who formed a number of large scale small groups with their members overlapped. Conclusion The overall activity level and communication frequency are low in breast cancer prevention and treatment information dissemination network users. The breast cancer prevention and treatment information dissemination network users, especially the isolated breast cancer prevention and treatment information dissemination network users should strengthen their interaction and communication, improve their contact and shorten their information dissemination distance. The breast cancer prevention and treatment information dissemination network users in non-core zones should improve their activity level and information dissemination capability, participate in a number of small groups, strengthen cross-group information exchange and expand their information dissemination scope. The breast cancer prevention and treatment information dissemination network users at the key nodes should ensure that the information they disseminated is scientific and authoritative, shorten the information update frequency, and ensure the health information level disseminated through microBlog.
