The study of persuasive health messages—their design, dissemination, and impact—is ubiquitous in the communication discipline. Words, sounds, and images—alone or in combination—can move people to change their minds and their bodies. Micro-level topics surround questions of message content (argumentation scheme, evidence, qualifying language, and figurative language), structure (message sidedness, standpoint articulation, inoculation, and sequential strategies), and format (channel and audiovisual effects). Macro-level topics in this area include message sensation value, narrative, framing, emotional appeals, and tailoring. Central theoretical frameworks used to guide message design research, include health behavior change theories, information processing theories, and theories/frameworks for message design. In addition, some of the methodoligical issues inherent in message design research are questions of analysis, validity, and measurement. Four streams of past scholarship that inform persuasive health message design research: Greek rhetoric, mass communication research begun during World War II, the development of health communication as a research focus within the communication discipline, and the development of computer and telecommunications technology. Directions and challenges for future research include the need for a clear, coherent, and comprehensive taxonomy to classify message characteristics and attention to several methodological issues.

Popular media are a source of information, a powerful socializing agent, and generate sociopolitical and sociocultural meanings that impinge on health promotion and/or disease prevention efforts and individual lived experiences. Thus, motivated by the goal of improving individual and social health, multidisciplinary scholars attend to the implications of entertainment and news media with regard to a range of topics such as individual health threats related to prevention, health conditions and illnesses, patient–provider interactions and expectations, public health issues related to crisis management and health recommendations, and public policy. Scholarship in this line of research may approach the study of popular media guided by the social scientific tradition of media effects theory to explain and predict response or by critical theory to consider ideological implications and employ different methodologies to describe and evaluate the images of health and health-related matters to which people are being exposed or that focus on media representations or audience (both individual and societal) response.

Health communication research has often focused on how features of persuasive health messages can directly influence the intended target audience of the messages. However, scholars examining presumed media influence on human behavior have underscored the need to think about how various audience’s health behavior can be unexpectedly influenced by their exposure to media messages. Two central theoretical frameworks have been used to guide research examining the unintended effects: the third-person effect and the influence of presumed media influence (IPMI). The theoretical explanations for presumed media influence is built on attribution bias, self-enhancement, perceived exposure, perceived relevance, and self-categorization. Even though both the third-person effect and the IPMI share some theoretical foundations, and are historically related, the IPMI has been argued to be better suited to explaining a broader variety of behavioral consequences. One major way that presumed media influence can affect an individual’s health behavior is through the shifting of various types of normative beliefs: descriptive, subjective, injunctive, and personal norms. These beliefs can manifest through normative pressure that is theoretically linked to behavioral intentions. In other words, media have the capability to create the perception that certain behaviors are prevalent, inculcating a normative belief that can lead to the uptake of, or restrain, health behaviors. Scholars examining presumed media influence have since provided empirical support in a number of specific media and behavioral health contexts. Existing findings provide a useful base for health communication practitioners to think about how presumed media influence can be integrated into health campaigns and message design. Despite the proliferation of research in this area, there remains a need for future research to examine these effects in a new media environment, to extend research into a greater number of health outcomes, to incorporate actual behavioral measures, and to ascertain the hypothesized causal chain of events in the model.

The historical construction of Indian in American popular culture poses serious challenges for conducting research about representations of indigenous culture, identity, and politics. Mass-mediated representation deserves specific attention, as popular entertainment has been one of the most significant historic battlegrounds over the status of indigenous identity in American culture. Representations of American Indians have been reworked and negotiated as they have circulated through a variety of mediums, including theatrical performances, silent films, Westerns, prime time television, independent films, advertising, sports culture, and so on.
Beginning with Buffalo Bill’s Wild West show and Thomas Edison’s kinetoscope, introduced the at the 1893 Chicago Columbian World’s Exposition, American mass entertainment has been preoccupied with the drama of westward expansion and the noble savage of the American frontier. Later, the films of John Ford developed the Hollywood image of the screen savage. Film continued to address the topic of American Indians through the lens of the 1960’s and 1970’s counterculture, 1980’s imperial nostalgia, 1990s sympathy and revisionism, and, in the 21st century, through native filmmaker’s reclamation of indigenous visual sovereignty. Not all media are uniform in their portrayals. The televisual Indian evolved quite differently than her/his counterpart in film. At some points, television has been even more progressive in its portrayals of American Indian characters, more willing to feature native actors and storylines than mainstream Hollywood film. Besides film and television, sports and advertising have had the most influence on popular conceptions of American Indians. While commodified images of American Indians are ubiquitous in popular culture, sport culture (mascots) has become the most popular site where Indian imagery is used to generate a profit. Struggles over everything from the moving image to sports mascots demonstrate the importance of studying the power of the image, particularly in the context of American settler colonialism.

During the past few decades we have witnessed increased academic attention on resistance to persuasion. This comes as no surprise, as people are often persuaded by external forces when making important decisions that may affect their health. Public health professionals, scholars, and other concerned parties have developed numerous trainings, interventions, and regulations to teach or assist people to resist unwanted persuasion, deriving from media exposure (e.g., advertising) or social pressure. The extant literature on resistance induction encompasses strategies such as inoculation, media literacy interventions, trainings on specific persuasive techniques, warnings, and social influence interventions. Although the research findings of the discussed strategies vary in how straightforward they are, they do offer promising avenues for policymakers and health communication professionals. Furthermore, several avenues worthy of further study can be identified.

Our understanding and perceptions of source credibility significantly drive how we process health and risk messages, and may also influence relevant behaviors. Source credibility is believed to be impacted by both perceptions of source trustworthiness and expertise, and the effect of credibility on changes in attitudes and behavior has been studied for decades in the persuasion literature. However, how we understand and define source credibility—particularly the dimension of expertise—has changed dramatically as social media and other online platforms are increasingly used to design and disseminate health messages. While earlier definitions of source credibility relied heavily on the source’s credentials as indicators of expertise on a given topic, more recent conceptualizations must also account for expertise held by laypeople who have experience with a health concern. This shifting conceptualization of source credibility may then impact both why and when people select, as well as how they perceive, process, and judge, health messaging across both novel and more traditional communication contexts.

In our modern age, electronic media usage is prevalent in almost every part of the world. People are more connected than ever before with easy access to highly portable devices (e.g., laptops, smartphones, and tablets) that allow for media consumption at any time of day. Unfortunately, the presence of violence in electronic media content is almost as prevalent as the media itself. Violence can be found in music, television shows, video games, and even YouTube videos. Content analyses have shown that nearly all media contain violence, irrespective of age rating (Linder & Gentile, 2009; Thompson & Haninger, 2001; Thompson, Tepichin, & Haninger, 2006; Yokota & Thompson, 2000). It is therefore important to ask: What are the consequences of pervasive exposure to screen violence? One consequence of media violence exposure, hotly debated by some in the general public, is increased aggressive behavior. This relationship was investigated in many studies using experimental, longitudinal, or cross-sectional design. These studies are summarized in meta-analyses, which support the notion that media violence increase the likelihood of acting aggressively. This link can be explained by an increase in aggressive thoughts, a more hostile perception of the environment, and less empathic reaction to victims of aggressive behavior. However, the often debated notion that media violence allows one to vent off steam, leading to a reduced likelihood of aggressive behavior, has failed to receive empirical support. The effect of media violence is not limited to aggressive behavior; as a consequence of violent media usage attentional problems arise and prosocial behavior decreases.
