Health and Risk Communication

Communication is typically understood in terms of what is communicated. However, the importance of what is intentionally or unintentionally left out from the communication process is high in many fields, notably in communication about environmental and health risks. The question is not only about the absolute lack of information. The rapidly increasing amount and variability of available data require actors to identify, collect, and interpret relevant information and screen out irrelevant or misleading messages that may lead to unjustified scares or hopes and other unwanted consequences. The ideal of balanced, integrative, and careful risk communication can only rarely be seen in real-life risk communication, shaped by competition and interaction between actors emphasizing some risks, downplaying others, and leaving many kinds of information aside, as well as by personal factors such as emotions and values, prompting different types of responses. Consequently, risk communication is strongly influenced by the characteristics of the risks themselves, the kinds of knowledge on them and related uncertainties, and the psychological and sociocultural factors shaping the cognitive and emotive responses of those engaged in communication. The physical, economic, and cultural contexts also play a large role. The various roles and factors of absent information in integrative environmental and health risk communication are illustrated by two examples. First, health and environmental risks from chemicals represent an intensively studied and widely debated field that involves many types of absent information, ranging from purposeful nondisclosure aimed to guarantee public safety or commercial interests to genuinely unknown risks caused by long-term and cumulative effects of multiple chemicals. Second, light pollution represents an emerging environmental and health issue that has gained only limited public attention even though it is associated with a radical global environmental change that is very easy to observe. In both cases, integrative communication essentially involves a multidimensional comparison of risks, including the uncertainties and benefits associated with them, and the options available to reduce or avoid them. Public debate and reflection on the adequacy of risk information and on the needs and opportunities to gain and apply relevant information is a key issue of risk management. The notion of absent information underlines that even the most widely debated risk issues may fall into oblivion and re-emerge in an altered form or under different framings. A typology of types of absent information based on frameworks of risk communication can help one recognize its reasons, implications, and remediation.

Results of national epidemiologic surveys indicate that substance use rates among adolescents remain relatively steady or even show slight declines; however, some substance use rates, such as electronic cigarettes, are actually rising. Thus, the need for efficacious drug prevention efforts in the United States remains high. Active Involvement (AI) interventions are a promising avenue for preventing and reducing adolescent substance use, and they create opportunities for adolescents to experience a core feature of engagement that is common to these interventions, such as producing videos, posters, or radio ads; or generating themes and images for messages such as posters.

Existing interventions grounded in theories of Active Involvement include programs delivered face-to-face and via e-learning platforms. Narrative Engagement Theory and the Theory of Active Involvement guide the components of change in AI interventions. Youth develop message content during participation in Active Involvement interventions. Advanced analytic models can be applied to address new research questions related to the measure of components of AI interventions.

Patient adherence (sometimes referred to as patient compliance) is the extent to which a patient’s health behavior corresponds with the agreed-upon recommendations of the healthcare provider. The term patient compliance is generally synonymous with adherence but suggests that the patient played a more passive role in the healthcare professional’s prescription of treatment, whereas the term adherence suggests that the patient and healthcare professional have come to an agreement on the regimen through a collaborative, shared decision-making process. Another term related to the concept of adherence is persistence (i.e., taking a medication for the recommended duration). Some patients are purposefully or intentionally nonadherent, whereas others are unintentionally nonadherent due to forgetfulness or poor understanding of the regimen. Patients may be intentionally nonadherent because of a belief that the costs of the regimen outweigh the benefits, for example. Nonadherence behaviors in medication-taking include never filling a prescription, taking too much or too little medication, or taking a medication at incorrect time intervals. Patient adherence is relevant not only in medication-taking behaviors, but also in health behaviors such as following a specific dietary regimen, maintaining an exercise program, attending follow-up appointments, getting recommended screenings or immunizations, and smoking cessation, among others.

There are a number of factors that predict patient adherence to treatment, but the relationship between provider-patient communication and adherence to treatment will be stressed here. Focusing on recent research, this article examines the concept of patient adherence, describes how provider-patient communication can enhance patient adherence, explains what elements of communication are relevant for adherence, and illustrates how interventions to improve communication can improve adherence.

Advertising as a field and industry often has a contentious relationship with both health communication and public health due to legitimate concerns about how advertising for certain products, such as alcohol and tobacco, could contribute to less-healthy decisions and behaviors. While acknowledging such concerns, advertisers and their approach to solving communication problems could also provide valuable lessons to those working in health communication. Indeed, advertising agencies are designed to develop creative and effective messages that change consumer behavior—and health communication practitioners and scholars aim to change population-level behavior as well. The perspective and approach of the account planner in the advertising agency—a role whose chief responsibility is to bring the consumer perspective into every step of the advertising development process and inspire effective and creative campaigns—would be particularly valuable to those working in health communication. It was account planning work that shifted traditional milk advertising from promoting it as a healthy drink to the iconic “got milk?” campaign, which positioned milk as a complement that makes other food better—an approach that drove positive sales after years of declining milk consumption. Yet many who work in health communication and public health often know little of how advertising agencies work or their internal processes that might be productively adopted. This lack of understanding can also lead to misperceptions of advertisers’ work and intentions. As an example, one might assume dense medical language in prescription drug advertising is intended to add unnecessary complexity to the advertisements and obscure side effects; instead, advertising professionals who work on prescription drug advertising have often been trained on clear communication—but cannot fully utilize that training because of regulations that require medically accurate terminology that might not be comprehensible to most viewers. Improved understanding of how advertisers can act as agents of change, and increased dialogue between the fields of advertising and health communication, could contribute to improved health communication research, practice, and policy.

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.

The concept of ambiguity tolerance (TA), variously called Uncertainty Avoidance, Ambiguity Avoidance, or Intolerance, can be traced back nearly 70 years. It has been investigated by many different types of researchers from clinical and differential, to neuro- and work psychologists. Each sub-discipline has tended to focus on how their variable relates to beliefs and behaviors in their area of expertise, from religious beliefs to reactions to novel products and situations.

The basic concept is that people may be understood on a dimension that refers to their discomfort with, and hence attempts to avoid, ambiguity or uncertainty in many aspects of their lives. There have been many attempts to devise robust and valid measures of this dimension, most of which are highly inter-correlated and require self-reporting. There remains a debate as to whether it is useful having just one or more dimensions/facets of the concept.

Using these tests, there have been many correlational studies that have sought to validate the measure by looking at how those high and low on this dimension react to different situations. There have also been some, but many fewer, experimental studies, which have tested very specific hypotheses about how TA is related to information processing and reactions to specific stimuli. There is now a welcomed interest by neuroscientists to explore the concept from their perspective and using their methodologies.

These studies have been piecemeal, though most have supported the tested hypotheses. There has been less theoretical development, however, of the concept attempting to explain how these beliefs arise, what sustains them, and how, why, and when they may change. However, the concept has continued to interest researchers from many backgrounds, which attests to its applicability, fecundity, and novelty.

Within a range of health communication contexts, anger can be either a detriment to the receptivity of health promotion messages when poorly controlled, or a benefit to information processing when appropriately directed. In the former case, anger can disrupt cognitive processing, leading to a range of negative outcomes, including emotional turbulence and a preoccupation with anger-eliciting events that can severely limit the receptivity of health promotion and risk prevention messages. However, when properly directed and elicited in moderation, anger can motivate greater purpose and resolve in response to health threats, stimulate more active processing of health warnings, sharpen focus on argument quality, and direct greater attention to coping-relevant information concerning harmful health risks.

Regret is the prototypical decision related emotion. It is felt when the outcome of a non-chosen alternative is better than the outcomes obtained. Regret is a functional emotion that helps people to correct mistakes. It is also functional because people can anticipate regret beforehand, then choose in such a way as to avoid regret from happening. Researchers in economics proposed regret theory, an alternative to rational choice theory, which takes into account the anticipation of regret and its influence in choice. Researchers in psychology studied how anticipations of regret influence decision making in a variety of domains, including health behaviors. The findings suggest that interventions can be developed that are based on the idea that people are regret averse.

Many health- and risk-related behaviors have moral implications. Most obvious are altruistic behaviors like blood donation. However, issues related to promoting the wellbeing of friends and family members, such as being sure that they don’t drive drunk, and the generalized obligations that attend environmentally relevant behaviors like participating in recycling programs, also tap into moral concerns. For promoting such issues, moral appeals may be appropriate. Moral appeals are messages that acknowledge individuals’ evaluative beliefs about universal rights and wrongs. Appeals to morality produce a sense of obligation and responsibility because morals are viewed as self-evident facts.

Three explanations for why people engage in moral behavior are discernible in current scholarship, each with implications for structuring moral appeals: activation of social expectations, activation of personal norms, and arousal of emotion. The first of these is based on the subjective expected utility tradition. From this perspective, the key to successfully encouraging morally relevant behavior is maximizing benefits and minimizing costs. Because prosocial behaviors are enforced by social sanctions, many of these costs and benefits are socially bestowed. Thus, altruism at its core is hedonism. Theories that focus on activation of personal norms, in contrast, contend that people sometimes make decisions to donate blood, demonstrate for healthcare reform, recycle, and so on simply because they view it as their duty and responsibility to do so. When people realize in a concrete situation that their actions have consequences for the welfare of others, and that they are personally responsible for those outcomes, personal norms for the specific case are generated from internalized moral values. In this view, a central concern with moral appeals is ensuring that messages are aligned with internalized norms and that relevance and personal responsibilities are clearly communicated. Finally, theories of emotional arousal stress that although cognitive appraisals of personal and social norms are necessary, they are insufficient to incite people to selfless behavior. Rather, people engage in helping or altruistic behavior because moral appeals are emotionally arousing. Emotions associated with such appeals include empathic concern and guilt. Guilt appeals especially have been found to be as effective in eliciting compliance when behaviors have moral significance as other popular compliance-gaining strategies. Positive emphasis on responsibility and induction of hypocrisy are also techniques that rely on the appeal to moral beliefs.

Bystander intervention is a form of helping that occurs when onlookers intercede to provide direct or indirect aid to a victim. When bystanders step in to prevent or reduce harm to others, they act as agents of primary and secondary health prevention. But theory and research suggest the bystander intervention process is complex and multiple social-psychological and situational barriers imperil bystander action. Bystanders are often ill-prepared to intervene when others are at risk for emotional or physical harm. They may not notice that someone needs help due to distraction from self-focus, engagement in social interaction, intoxication, or aspects of the situation like crowding or noise. Due to inadequate knowledge, bystanders may misdiagnose the situation and believe intervention is unnecessary. The negative consequences of nonintervention may be unknown to them such that the situation fails to increase their empathic arousal and motivate their action. Lacking knowledge, they may not recognize the seriousness of the situation and or the potential costs of inaction, and so are insufficiently alarmed. Pluralistic ignorance can arise when multiple uncertain bystanders conceal their concern and hesitate to act, assuming others’ inaction means intervention is inappropriate or unnecessary. When there are multiple witnesses, bystanders may assume their help is unneeded, place intervention responsibility on others, or feel less responsible for helping due to diffusion of responsibility. When the victim is not a member of their in-group, or is assumed at fault for their predicament, they may feel less empathy and a reduced responsibility to help. Or, bystanders may assign responsibility for intervention to the victim’s friends or fellow in-group members, or to those “in charge” of the setting. Even when bystanders realize help is needed and take responsibility for helping, they may not act if they do not know how or lack confidence in their ability to successfully carry out the actions required to help. When they have the skills, they may not help if they perceive the costs of action to outweigh the benefits of action. Audience inhibition arising from group norms supporting inaction and from bystander worry about what others will think about them if they act unnecessarily or ineptly can prevent bystander action by increasing bystanders’ perceived helping costs.

Recognition of bystanders as a potentially valuable public health asset has increased interest in promoting bystander intervention. Bystander intervention promotion and communications empower bystander action by combating intervention- and audience-specific barriers to bystander intervention using targeted information, communications, and skills training. Theory and research suggest that effective promotions and communications foster context-specific attitudes, beliefs, norms, and skills such that bystanders: (1) are able to quickly and accurately identify a situation as intervention-appropriate; (2) experience action-motivating arousal (including empathy) in the face of the event; (3) have positive attitudes towards intervention and perceive the benefits of action as outweighing the perceived costs; (4) are empowered to act and feel confident in their ability to effectively intervene (bystander efficacy); and (5) are resistant to evaluation apprehension and norms contraindicating action. Effective bystander intervention promotion draws on social psychology and communications studies, and best practices for health promotion and prevention programs. The application of social marketing and formative and summative program evaluation methods enhance the potential of bystander intervention promotions and communications to empower bystander action.
