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.

Beginning with phone calls to an emergency psychiatric hospital and suicide prevention center, the roots of Conversation Analysis (CA) are embedded in systematic analyses of routine problems occurring between ordinary persons facing troubling health challenges, care providers, and the institutions they represent. After more than 50 years of research, CA is now a vibrant and robust mode of scientific investigation that includes close examination of a wide array of medical encounters between patients and their providers. Considerable efforts have been made to overview CA and medicine as a rapidly expanding mode of inquiry and field of research. Across a span of 18 years, we sample from 10 of these efforts to synthesize important priorities and findings emanating from CA investigations of diverse interactional practices and health care institutions. Key topics and issues are raised that provide a unique opportunity to identify and track the development and maturity of CA approaches to medical encounters. Attention is also given to promising new modes of research, and to the potential and challenges of improving medical practices by translating basic and rigorous empirical findings into innovative interventions for medical education. A case is made that increasing reliance on CA research can positively impact training and policies shaping the delivery of humane and quality medical care.

Health literacy—defined as the ability of an individual to obtain, process, understand, and communicate about health information—contributes significantly to health outcomes and costs to the U.S. health-care system. Approximately one-quarter to one-half of U.S. adults struggle with health information, which includes understanding patient education materials, reading medication labels, and communicating with health-care providers. Low health literacy is more common among the elderly, those who speak English as a second language, and those of lower socioeconomic status. In addition to conceptualizing health literacy as an individual-level skill, it can also be considered an organizational or community-level ability.
Increased attention to the field of health literacy has resulted in debates about the definition and the best ways to assess health literacy; there is also a strong and growing movement within the field of health literacy research and practice to frame health literacy less as a deficit to overcome and more as an approach to empowering patients and improving outcomes. As health-care providers have recognized the importance of health literacy, workshops, and training programs have been developed and evaluated to improve the care of low-health-literate patients. Similarly, health promotion professionals have developed best practices for reaching low-health-literate audiences with traditional and new digital media, which can also increase access for patients with hearing or visual impairments. Additionally, recent policy changes in the United States, including those related to the Affordable Care Act, contribute to a greater focus and regulation of factors that impact health literacy. Researchers and practitioners together are advancing understanding of health literacy, its relationship to health outcomes and health-care costs, and improved strategies for improving the health of lower health literate patients. Development and review of health literacy pieces can aid in shared decision making and provide insights for patients on various health-care services.

For many decades, the field of risk messaging design, situated within a broader sphere of public health communication efforts, has endeavored to improve its response to the needs of U.S. immigrant and refugee populations who are not proficient speakers of English, often referred to as limited English proficient (LEP) populations. Research and intervention work in this area has sought to align risk messaging design models and strategies with the needs of linguistically diverse patient populations, in an effort to improve patient comprehension of health messages, promote informed decision-making, and ensure patient safety. As the public health field has shifted from person-centered approaches to systems-centered thinking in public health outreach and communication, the focus in risk messaging design, in turn, has moved from a focus on the effects of individual patient misunderstanding and individual patient error on health outcomes, to structural and institutional barriers that contribute to breakdown in communication between patients and healthcare providers.
While the impact of limited proficiency in English has been widely documented in multiple spheres of risk messaging communication research, the processes by which members of immigrant and refugee communities actually come to understand sources of risk and act on risk messaging information remain poorly researched and understood. Advances in risk messaging efforts are constrained by outdated views of language and communication in healthcare contexts: well-established lines of thinking in sociolinguistics and language education provide the basis for critical reflection on enduring biases in public health about languages other than English and the people who speak them. By drawing on important findings about language ideologies and language learning, an alternative approach would be to cultivate a deeper appreciation for the linguistic diversity already shaping our everyday lives and the competing views on this diversity that constrain our risk messaging efforts.
The discourse surrounding the relationship between LEP and risk messaging often omits a critical examination of the deficit-based narrative that tends to infuse many risk messaging design efforts in the United States. Sociolinguists and language education specialists have documented the enduring struggle against a monolingual bias in U.S. education and healthcare policy that often privileges proficiency in English, and systematically impedes and discriminates against emerging bilingualism and multilingualism. The English-only bias tends to preclude the possibility that risk messaging comprehension for many immigrant and refugee communities may represent a multilingual capacity, as patients make use of multiple linguistic and cultural resources to make sense of healthcare messages. Research in sociolinguistics and immigration studies have established that movement across languages and cultures—a translingual, transcultural competence—is a normative component of the immigrant acculturation process, but these research findings have yet to be fully integrated into risk messaging theory and design efforts. Ultimately, critical examination of the role of language and linguistic identity (not merely a focus on proficiency in English) in risk messaging design should provide a richer, more nuanced picture of the ways that patients engage with health promotion initiatives, at diverse levels of English competence.

Typical discussion about the success of mediated health communication campaigns focuses on the direct and indirect links between remembered campaign exposure and outcomes; yet, what constitutes information exposure and how it is remembered remain unclearly defined in much health communication research. This problem mainly stems from the complexity of understanding the concept of memory. Prolific discussions about memory have occurred in cognitive psychology in recent decades, particularly owing to advances in neuroimaging technologies. The evolution of memory research—from unitary or dichotomous perspectives to multisystem perspectives—has produced substantial implications for the topics and methods of studying memory. Among the various conceptualizations and types of memory studied, what has been of particular interest to health-communication researchers and practitioners is the notion of “encoded exposure.” Encoded exposure is a form of memory at least retrievable by a potential audience member through a conscious effort to recollect his or her past engagement with any particular unit of campaign content. While other aspects of memory (e.g., non-declarative or implicit memory) are certainly important for communication research, the encoded exposure assessed under a retrieval condition offers a critical point at which to establish the exposure-outcome link for the purpose of campaign design and evaluation. The typical methods to assess encoded exposure include recall and recognition tasks, which can be exercised in various ways depending on retrieval cues provided by a researcher to assess different types and levels of cognitive engagement with exposed information. Given that encoded exposure theoretically relies on minimal memory trace, communication scholars have suggested that recognition-based tasks are more appropriate and efficient indicators of encoded exposure compared to recall-based tasks that require a relatively high degree of current-information salience and accessibility. Understanding the complex nature of memory also has direct implications for the prediction of memory as one of the initial stages of communication effects. Some prominent message-level characteristics (e.g., variability in the structural and content features of a health message) or message recipient-level characteristics (e.g., individual differences in cognitive abilities) might be more or less predictive of different memory systems or information-processing mechanisms. In addition, the environments (e.g., bodily and social contexts) in which people are exposed to and interact with campaign messages affect individual memory. While the effort has already begun, directions for future memory research in health communication call for more attention to sharpening the concept of memory and understanding memory as a unique or combined function of multilevel factors.
Message Recipient Psychological Characteristics: Incurious and Curious Motives to Learn about Health Risks
Successfully conveying information about the risk of potential threats to an individual’s physical and mental health is a serious challenge for healthcare practitioners. Adding to the challenge is the role of individual differences in people’s tendencies to want to learn (or in their choice to passively avoid) new information. These characteristic motives can be both curious and incurious in nature and interact with the perceived locus of the relevant health threat, which must be taken into account first. Some health threats are relatively “external,” and involve addressing the potential risk of an undesired event (e.g., developing illness, encountering relationship troubles). Research indicates that individuals who view external threats as “controllable” are more likely to respond positively to relevant information, but perception of control alone does not determine whether health-relevant information is likely to be sought or acted on. Besides perceived controllability, individual differences in incurious worry reduction motives (IWRM) play an important role as well. Two different kinds of IWRM have been identified: focus on distress (IWRM-FD) and focus on relief (IWRM-FR). Dispositional tendencies toward IWRM-FD are associated with greater willingness to seek out information when risk is perceived as low (i.e., information about the potential external threat is expected to make one feel better), but a tendency to passively avoid any information when risk is considered high (i.e., information is expected to intensify distress). In contrast, tendencies toward IWRM-FR reflect wanting more information about potential threats when risk is believed to be high, while passively avoiding news when perceived risk is low. In regard to coping with perceived risk, IWRM-FD scores predict avoidant coping, whereas IWRM-FR levels are associated with proactive coping and seeking others’ advice.
Other risks are more “internal,” and involve threats to an individual’s certainty about his or her self-concept, purpose in life, or the wisdom of past behavior; in short, an “identity crisis.” Such threats underlie wondering things like “Who am I, really?” and are associated with less self-awareness, lower self-esteem, and greater overall distress. In response to internal threats, intrapersonal curiosity (InC) motivates individuals to engage in introspective self-exploration that may help them to clarify, to elaborate on, and to improve their understanding of their self-concept. Recent research has found that individual differences in InC are positively associated with IWRM, suggesting that dealing with identity crises involves the desire to better know oneself, as well as wishing to mitigate worries about experiencing self-doubt.
Bearing the above in mind, research on individual differences in tendencies to avail oneself of different coping strategies indicates that proactive coping (e.g., positive reframing, seeking advice) tends to result in beneficial outcomes, such as personal growth and improved health, but some proactive strategies are “double-edged” and may lead to some negative outcomes as well. In particular, proactive strategies like acceptance of one’s limitations or discussing them with others when seeking social support were helpful, but they also had the potential to leave individuals feeling less sure of themselves. These findings suggest that practitioners who wish to more effectively communicate information about risk of potential health threats should consider whether the nature of the threat is internal or external, the role of individual differences in IWRM and InC, and how to help their patients to focus on the positive benefits of acceptance (i.e., identify solvable problems) and seeking social support (i.e., acquiring useful advice) over the negative aspects (i.e., admitting limitations).
Metaphor equates two concepts or domains of concepts in an A is B form, such that a comparison is implied between the two parts leading to a transfer of features typically associated with B (called source) to A (called target). Metaphor is evident in written, spoken, gestural, and pictorial modalities. It is also present as latent patterns of thought in the form of conceptual mappings between domains of experience called conceptual metaphor. Metaphor is found commonly in a variety of health and risk communication contexts, including public discourse, public understanding and perceptions, medical encounters, and clinical assessment. Often metaphor use is beneficial to achieving desired message effects; however, sometimes its use in a message can lead to unintended undesirable effects. There is a general consensus, although not complete agreement, that metaphors in messages are processed through engagement with corresponding conceptual mappings. This matching process can be taken as a general principle for design of metaphor-based health and risk messages.

In today’s media-saturated environment, individuals may be exposed to hundreds of media messages on a wide variety of topics each day. It is impossible for individuals to attend to every media message, and instead, they engage in the phenomenon of selective exposure, where certain messages are chosen and attended to more often than others. Health communication professionals face challenges in creating messages that can attract the attention of targeted audiences when health messages compete with more entertaining programming. In fact, one of the greatest obstacles for health campaigns is a lack of adequate exposure among targeted recipients. Individuals may avoid health messages completely or counterargue against persuasive attempts to change their health-related attitudes and behaviors. Once individuals have been exposed to a health message, their current mood plays an important role in the processing of health information and decision making. Early research indicated that a positive mood might actually be detrimental to information processing because individuals are more likely to process the information heuristically. However, recent studies countered these results and suggested that individuals in positive moods are more likely to attend to self-relevant health information, with increased recall and greater intent to change their behaviors.
Since mood has the ability to influence exposure to health messages and subsequent message processing, it is important for individuals to be able to manage their mood prior to health information exposure and possibly even during exposure. One way individuals can influence their moods is through media use including TV shows, movies, and music. Mood management theory predicts that individuals choose media content to improve and maintain positive moods and examines the mood-impacting characteristics of stimuli that influence individuals’ media selections. Therefore, an individual’s mood plays an important role in selection of any type of communication (e.g., news, documentaries, comedies, video games, or sports).
How can health message designers influence individuals’ selection and attention to health messages when negative moods may be blocking overtly persuasive attempts to change behaviors and a preference for entertaining media content? The narrative persuasion research paradigm suggests that embedding health information into entertainment messages may be a more effective method to overcome resistance or counterarguing than traditional forms of health messages (e.g., advertisements or articles). It is evident that mood plays a complex role in message selection and subsequent processing. Future research is necessary to examine the nuances between mood and health information processing including how narratives may maintain positive moods through narrative selection, processing, and subsequent attitude and/or behavior change.

In health and risk communication, evidence is a message feature that can add credibility, realism, and legitimacy to health and risk messages. Evidence is usually defined into two types: statistical or narrative. Statistical evidence employs quantifications of events, places, phenomena, or other facts, while narrative evidence involves stories, anecdotes, cases, or testimonials. While many health and risk messages employ statistical or factual information, narrative evidence holds appeal for health and risk communication for its utility in helping individuals learn their risks and illnesses through stories and personal experiences. In particular, narratives employed as evidence in a health or risk message especially hold value for their ability to communicate experiences and share knowledge, attitudes, beliefs, and ideas about complex health issues, propose behavior change, and assist individuals coping with disease. As a result, the personal experiences shared, whether they are from first-hand knowledge, or recounting another’s experience, can focus attention, enhance comprehension for risks, and recall of health and risk information. Furthermore, readers engage with the story and develop their own emotional responses which may align with the purpose of the health and risk message. Narratives, or stories, can occur in many ways or through various points of view, but the stories that “ring true” to readers often have a sense of temporality, coherence, and fidelity. As a result, formative research and pre-testing of health and risk messages with narratives becomes important to understand individual perceptions related to the health issue and the characters (or points of view). Constructs of perceived similarity, interest, identification, transportation, and engagement are helpful to assess in order to maximize the usefulness and persuasiveness of narratives as evidence within a health and risk message. Additionally, understanding the emotional responses to narratives can also contribute to perceptions of imagery and vividness that can make the narrative appealing to readers. Examining what is a narrative as evidence in health and risk messages, how they are conceptualized and operationalized and used in health and risk messages is needed to understand their effectiveness.

Rhetoric, commonly understood as the art, practice, and analysis of persuasion, has longstanding connections to medicine and health. Rhetorical scholars, or rhetoricians, have increasingly applied rhetorical theories, concepts, and methods to the texts, contexts, discourses, practices, materials, and digital and visual artifacts related to health and medicine. As an emerging interdisciplinary subfield, the rhetoric of health and medicine seeks to uncover how symbolic patterns shape thought and action in health and medical texts, discourses, settings, and materials.
In practice, rhetoricians who study health and medicine draw from the standard modes of rhetorical analysis, such as rhetorical criticism and rhetorical historiography, as well as from social science methods—including participant observation, interviewing, content analysis, and visual mapping—in order to deepen understanding of how language functions across health and medical objects, issues, and discussions. The objects of analysis for rhetorical studies of health and medicine span medical research, education, and clinical practice from laboratory notes to provider–patient interaction; health policymaking and practice from draft policies through standards of care; public health texts and artifacts; consumer health practices and patient advocacy on- and offline; public discourses about disease, death, bodies, illness, wellness, and health; online and digital health information; popular entertainments and medical dramas; and alternative and complementary medicine. Despite its methodological breadth, rhetorical approaches to science and medicine consistently involve the systematic examination and production of symbolic exchanges occurring across interactional, institutional, and public contexts to determine how individuals and groups create knowledge, meanings, identities, understandings, and courses of action about health and illness.
