Since McCombs and Shaw first introduced the theory in 1972, agenda setting has emerged as one of the most influential perspectives in the study of the effects of mass media. Broadly defined, “agenda setting” refers to the ability of mass media sources to identify the most salient topics, thereby “setting the agendas” for audiences. In telling us what to think about, then, mass media sources are perceived to play an influential role in determining priorities related to policies, values, and knowledge on a given topic or issue.
Scholars have studied this phenomenon according to both object (issue) salience and attribute salience and along aggregate and individual audience responses. The audience characteristics of need for orientation, uncertainty, relevance, and involvement are advanced as moderating and predicting agenda-setting effects. When agenda-setting theory is applied to the study of messaging related to health and risk communication, scholars have reviewed and identified common themes and topics that generally include media’s role in educating and informing the public about specific health conditions as well as public health priorities and administrative policies.
Agenda setting is often examined in terms of measuring mass media effects on audiences. Looking at interpersonal communication, such as that coming from medical providers, opinion leaders, or peer networks, in studies will allow research to examine the combined effects of interpersonal and mass communication. Testing possible interactions among differing sources of information along with assessment of issue and attribute salience among audiences according to an agenda-setting framework serves to document audience trends and lived experiences with regard to mass media, health, and risk communication.

Broadly speaking, cybervetting can be described as the acquisition and use of online information to evaluate the suitability of an individual or organization for a particular role. When cybervetting, an information seeker gathers information about an information target from online sources in order to evaluate past behavior, to predict future behavior, or to address some combination thereof. Information targets may be individuals, groups, or organizations. Although often considered in terms of new hires or personnel selection, cybervetting may also include acquiring and using online information in order to evaluate a prospective or current client, employee, employer, romantic partner, roommate, tenant, client, or other relational partner, as well as criminal, civil, or intelligence suspects. Cybervetting takes advantage of information made increasingly available and easily accessible by regular and popular uses and affordances of Internet technologies, in particular social media. Communication scholars have long been interested in the information seeking, impression management, surveillance, and other processes implicated in cybervetting; however, the uses and affordances of new online information technologies offer new dimensions for theory and research as well as ethical and practical concerns for individuals, groups, organizations, and society.
