Research indicates that misperceptions that become part of people's initial mental models about an issue tend to persist and influence their attitudes even after the misperception has been corrected. Recent work on evolving mental models suggests that communication efforts about the ongoing COVID-19 pandemic and its aftermath may be improved by crafting messages that acknowledge biases and misunderstandings about the virus and other infectious diseases that may remain among members of the target audience. This study was designed to provide insight into such biases by: (1) establishing salient categories of COVID-related misperceptions in the earliest months of the pandemic in the United States among (a) the general population, and (b) demographic sub-populations at high risk of severe health outcomes; (2) identifying demographic predictors of misperceptions; and (3) examining the relationship between consumption of different television news outlets and agreement with misperceptions about COVID-19.

Developing continuing medical education (CME) training programs is a strategy for communicating emerging science to health practitioners. This research tests the feasibility of using CME modules for translating and disseminating research findings from the Breast Cancer and Environment Research Program. Recent findings have identified certain windows of susceptibility, like during puberty, in which exposure to endocrine-disrupting chemicals can increase breast cancer risk later in life.

This formative study investigates the utility of the social norms approach (SNA) and self-determination theory (SDT) in framing safe bicycling messages with the goal of increasing intention to use bicycle lanes on a university campus. In Study 1, observational data showed that the majority of campus bicyclists did not use designated bike lanes while cycling; thus, intention to use bicycle lanes was chosen as the dependent variable for Study 2. Survey data (n = 168) collected from college students measured SNA and SDT constructs related to intention to use bicycle lanes, including descriptive norms, injunctive norms, autonomy, competence, and relatedness.

Choosing a primary care physician for the first time is an important decision, one that health care systems do not make particularly easy for prospective patients to make solely through the limited information provided on their websites. Without knowledge from others, a new patient is likely to have uncertainty about the physician he or she chooses. Three hundred and twenty participants completed an online experiment and were exposed to two biographies of different doctors with different media and either professional or personal information.

This study investigated whether state communication apprehension (CA) with physicians, for high CA patients, can be reduced before consultations by manipulating information found within physicians' online biographies. Participants were presented with three experimentally manipulated physician biographies and asked to choose which physician they would want to visit to get a hypothetical ailment checked out. Guided by uncertainty reduction theory, results support a path model where increases in perceived similarities between a patient and doctor led to greater uncertainty reduction, greater liking, and subsequent reductions in CA with the physician for high CA participants.

Searching for ways to reach wider audiences in more comprehensible ways, health promotion agencies might add videos to their current web offerings. While potentially costly and time consuming to create, the effect of these videos on websites has not received much attention. This study translated research about the potential breast cancer risk for young girls associated with the household chemical PFOA into two websites mothers with young daughters were randomly assigned to view (website with videos vs.

Health risks are often communicated to the lay public in statistical formats even though low math skills, or innumeracy, have been found to be prevalent among lay individuals. Although numeracy has been a topic of much research investigation, the role of math self-efficacy and math anxiety on health and risk communication processing has received scant attention from health communication researchers. To advance theoretical and applied understanding regarding health message processing, the authors consider the role of math anxiety, including the effects of math self-efficacy, numeracy, and form of presenting statistics on math anxiety, and the potential effects for comprehension, yielding, and behavioral intentions.

Emerging scientific findings regarding breast cancer science are typically presented only in discipline specific journals in which the general public and those at risk have limited access, creating a development-to-delivery gap between the state of the science and public knowledge. A lack of collaboration between scientists, communication experts, and community partners further compounds this lack of information available to the public. The present study translates recent scientific findings about environmental breast cancer risks into palatable magazine-style messages for mothers of young daughters as a strategy to meet the call for greater translation and dissemination of scientific results to the lay public.

Recent research links perfluorooctanoic acid (PFOA) to increased breast cancer risk. Efforts to inform the lay public about potential risks associated with PFOA need to be accessible in their content as many individuals, including highly educated ones, have low scientific literacy. This study investigates the role of message format, as well as personal involvement, scientific literacy, and education in influencing attitudes about PFOA regulation.

The present study surveyed mothers with daughters (N = 386) to investigate how mothers' concern about their daughters' breast cancer risk influenced intentions to engage in preventive behaviors. Using protection motivation theory as a framework, self-efficacy, response efficacy, and level of concern were posited to influence protective behavioral intention in distinct ways. Results from regression analyses indicate that self-efficacy, response efficacy, and mothers' concern are significant predictors of intentions to engage in preventive behaviors with daughters.

Social norms research has identified a range of distinct norms based on different referent groups that confer influence across a number of behaviors. The current survey study extends social norms research in two ways. First, this research tests the distinctiveness of four types of social norms: distal peer descriptive, distal peer injunctive, proximal peer descriptive, and proximal peer injunctive norms.

Researchers, practitioners, and participants in cancer clinical trials must have a clear understanding of clinical trials if participation in them is to be solicited ethically and effectively. A valid and reliable measure of cancer clinical trial understanding did not exist prior to a 2005 study conducted for the Coalition of Cooperative Cancer Groups. This report outlines a measure derived from that study, discusses the rationale for its component items, examines its psychometric properties, and demonstrates the relationship of this measure to the enrollment decision.

The current study examined whether self-efficacy (SE), response efficacy (RE), and personal responsibility (PR) affect mothers' intentions (N=139) to teach their adolescent and pre-adolescent daughters about breast cancer risk reduction measures such as maintaining a healthy diet, exercising on a regular basis, and avoiding chemical exposures. Results showed that both SE and RE were related to mothers' intentions to teach their daughters how to maintain a healthy diet, engage in regular exercise behavior, and avoid chemical exposures. However, PR was not related to any behavioral intention.

The incidence of neural tube defects (NTDs), serious birth defects of the brain and spine that affect approximately 3,000 pregnancies in the United States each year, can be reduced by 50-70% with daily periconceptional consumption of the B vitamin folic acid. Two studies were designed to assess college women's reactions to and perceptions of potential campaign advertising concepts derived from preproduction formative research to increase folic acid consumption through the use of a daily multivitamin. Study one assessed draft advertising concepts in eight focus groups (N = 71) composed of college-enrolled women in four cities geographically dispersed across the United States.

Recent research indicates environmental factors and personal behaviors are related to breast cancer risk, but adopting a healthy lifestyle as early as adolescence can serve a protective function. To investigate perceptions of breast cancer risk and the environment, 10 focus groups (N = 91) were conducted with adolescent females (n = 55) and mothers (n = 36) across four counties in the Midwest, USA. The Uncertainty Management Theory provides a framework for discussing statements, and results suggest that uncertainty is maintained through ambiguity about environmental risk factors and breast cancer.
