摘要与传统媒体不同，社交媒体系统通常在单个消息窗格中呈现来自不同类型贡献者的不同类型的信息，这是挑战传统健康传播处理的潜在影响的并列。一种类型的社交媒体系统，问答建议系统，提供同龄人对健康相关问题的答案，其他同龄人阅读和评级。回答可能看起来好或坏，回答者可能声称专业知识，其他人对答案有用性的综合评价可能会影响读者的判断。一项实验探讨了答案的可行性，专业知识的要求，以及用户生成的评级如何影响读者对匿名艾滋病毒检测建议的评估。结果扩展了说服的竞争系统模型（Chaiken，1980）和说服理论（Walther & Parks，2002）。通常与系统和启发式过程相关的信息会影响读者的评价。此外，内容层面的线索影响判断的消息来源出乎意料。当存在相互冲突的线索时，具有更大保证价值的线索（用户生成的共识评级）对结果的影响比不太有保证的线索（自我推销的专业知识）更大。研究结果提出了一个挑战，卫生专业人员的关注在线健康信息系统的可靠性。
ABSTRACT Unlike traditional media, social media systems often present information of different types from different kinds of contributors within a single message pane, a juxtaposition of potential influences that challenges traditional health communication processing. One type of social media system, question-and-answer advice systems, provides peers’ answers to health-related questions, which yet other peers read and rate. Responses may appear good or bad, responders may claim expertise, and others’ aggregated evaluations of an answer’s usefulness may affect readers’ judgments. An experiment explored how answer feasibility, expertise claims, and user-generated ratings affected readers’ assessments of advice about anonymous HIV testing. Results extend the heuristic–systematic model of persuasion (Chaiken, 1980) and warranting theory (Walther & Parks, 2002). Information that is generally associated with both systematic and heuristic processes influenced readers’ evaluations. Moreover, content-level cues affected judgments about message sources unexpectedly. When conflicting cues were present, cues with greater warranting value (consensus user-generated ratings) had greater influence on outcomes than less warranted cues (self-promoted expertise). Findings present a challenge to health professionals’ concerns about the reliability of online health information systems.
