Two areas of communication research are germane to health:
Message Production
Examines the social and organizational factors in media work that shape the creation of content that may influence health behavior
Interest is on message production processes for creating news, information, advertising and entertainment
Media Effects
Examines consequences of media exposure on individuals, groups, institutions and social systems
Outcome of media dissemination if images, ideas, themes and stories are commonly discussed
Looks at audiences not as passive recipients but as active seekers and users of information
Media effects research has changed from its dominant focus from attitude to studying the cognitive impact and emphasizing formation of community agendas and social systems level of analysis
Individual Level Theories
Theories used at the individual level include: Theory of Reasoned Action (TRA) (chapter four), Health Belief Model (chapter three) and Social Cognitive Theory (chapter eight).
The Integrative Behavioral Model (IBM) has been recently introduced to bring these theories together and apply them to the context of explaining media effects on marijuana use and sexual behavior.
Integrative Behavioral Model (IBM)
IBM argues that human behavior is influenced by a core set of determinants, including, perceived susceptibility (risk), norms and beliefs of the social environment, attitudes toward the message, self-efficacy and intentions to change.
Understanding how these factors relate to and influence each other can help predict behavior.
Key proposition is that media effects vary depending on the behavior and population under study.
Media messages can be targeted depending on which set of beliefs could most likely influence behavioral intentions.
Information Processing Theories
Information processing theories focus on how media messages may lead to changes in attitudes or in reinforcing existing attitudes
They provide explanations for how message elements are critical ingredients that interact with motivation and ability to influence information processing.
Two relevant theories
Elaboration Likelihood Models (ELM)
Heuristic-Systematic Processing Model (HSM)
Both theories imply that persuasive messages, such as anti-smoking messages, may be processed in two possible ways:
A central or systematic processing route involving deliberate, thoughtful weighing of message arguments and the changes accompanying such processing are likely to be more enduring
Alternatively, peripheral or heuristic processing occurs in low motivation conditions and the recipient relies on peripheral or heuristic processing such as celebrity status of a spokesperson pitching a product.
Message Effect Theories
Focus on the elements of execution in a message.
Assumes that formats and construction of message messages interact with attitudes and abilities to influence information processing.
Commonly investigated elements include framing, exemplification, narratives and sensation seeking.
Framing refers to how messages frame an argument which could be positively or negatively.
E.g. presenting the advantages of quitting smoking or emphasizing the consequences of not quitting
Framing can also be defined based on the frame sponsors and culture
E.g. abortion has been framed as "pro-choice" or "pro-life" which lends different interpretations to the same issue and potentially different effects on the audience
Elements of Message Effect Theories
Exemplars are constructed to serve as illustrations of a general class of events.
Exemplars that are simple, emotional and concrete are most effective.
Narratives are stories with a persuasive twist.
Narratives have been used to promote family planning, AIDS education and healthy lifestyles.
It is widely believed that narratives have powerful effects on the audience but systematic evidence is at a nascent stage of accumulation.
Sensation Seeking is a personality trait that is characterized by search for novelty, thrill seeking and impulsive decision-making and which influences attention, processing and comprehension of messages.
Sensation seekers prefer intensity and stimulation in their experiences and are more likely to indulge in risky behaviors such as illicit drugs use.
Messages with high sensation values are more likely to be effective among this audience, as they have been successfully used in discouraging drug use and promoting safe sex.
