Misinformation can influence personal and societal decisions in detrimental ways. Not only is misinformation challenging to correct, but even when individuals accept corrective information, misinformation can continue to influence attitudes: a phenomenon known as belief echoes, affective perseverance, or the continued influence effect. Two controlled experiments tested the efficacy of narrative-based correctives to reduce this affective residual in the context of misinformation about organic tobacco. Study 1 (N = 385) tested within-narrative corrective endings, embedded in four discrete emotions (happiness, anger, sadness, and fear). Study 2 (N = 586) tested the utility of a narrative with a negative, emotional corrective ending (fear and anger). Results provide some evidence that narrative correctives, with or without emotional endings, can be effective at reducing misinformed beliefs and intentions, but narratives consisting of emotional corrective endings are better at correcting attitudes than a simple corrective. Implications for misinformation scholarship and corrective message design are discussed.

News frames can influence how people think about disease. In a pair of studies, we demonstrate how contemporary news outlets frame cancer and how exposure to common frames can affect news audiences' perceptions of those who suffer from cancer. First, we examine the current landscape of frame usage in online cancer news, employing frames ideally suited to the depiction of health and disease. We compare our results with previously published research in this news domain. Second, we employ these frames in a multimessage experiment to assess the influence of cancer news framing on individuals' perceptions about cancer, cancer interventions, and those with cancer. We conclude with a discussion of implications for framing research and health news production.

Background Exposure to advertisements for tobacco products and tobacco warning labels evokes emotions. This study evaluated the association of discrete positive and negative emotions with interest in alternative tobacco products. Methods In 2013, 1,226 US adult non-smokers and current smokers viewed advertisements for moist snuff, snus, and electronic cigarettes with various warning labels and then indicated their emotional responses in terms of anger, anxiety, sadness, guilt, disgust, discouragement, hope, and contentment. Outcomes were openness to using moist snuff, snus, and e-cigarettes in the future and interest in a free sample of each product. Data were analyzed in 2016. Results Hope was positively associated with openness and interest across all alternative tobacco products as was contentment for moist snuff and snus. Anger was negatively associated with openness to moist snuff and e-cigarettes, disgust negatively – to moist snuff and snus, and anxiety negatively – to e-cigarettes. Being a current smoker, ever trying a corresponding product, being male and younger age were associated with greater openness to and interest in moist snuff and snus. For e-cigarettes, being a current smoker, ever trying e-cigarettes, and being female were associated with greater openness, and being a current smoker was associated with greater odds of selecting a free sample. Conclusions Positive emotions, particularly hope, were consistently positively associated with interest in alternative tobacco products. Hope is widely used by tobacco and e-cigarette companies to advertise their products. Anti-tobacco messages should aim to lower hope associated with tobacco products, but increase hope for cessation or life without tobacco.

The purpose of the study is to investigate how vaping marijuana, a novel but emerging risky health behavior, is portrayed on YouTube, and how the content and features of these YouTube videos influence their popularity and retransmission. A content analysis of vaping marijuana YouTube videos published between July 2014 to June 2015 (n = 214) was conducted. Video genre, valence, promotional and warning arguments, emotional appeals, message sensation value, presence of misinformation and misleading information, and user-generated statistics, including number of views, comments, shares, likes and dislikes, were coded. The results showed that these videos were predominantly pro-marijuana-vaping, with the most frequent videos being user-sharing. The genre and message features influenced the popularity, evaluations, and retransmission of vaping marijuana YouTube videos. Theoretical and practical implications are discussed.

The findings of this study provide causal support for the need for further regulatory action to address the potentially harmful ramifications of claims used in NAS advertising.

The Internet is one of the fastest growing news sources for many worldwide (Pew Research Center's Project for Excellence in Journalism, 2011), and cancer news is one frequently consumed form of online health information (Google, Inc., 2007). This content analysis of online cancer news (n = 862) retrieved from the four most frequented news websites describes trends regarding specific cancers, stages in the cancer continuum, and types of news articles. In general, treatment information received the most attention in online cancer news. Breast cancer received the most attention of each specific cancer, followed by digestive and genitourinary cancers. Research reports and profiles of people (more than 60% of which were about celebrities) were the most common article types. Risk, uncertainty, and clinical trials were also present across several types of cancer news articles. Implications of content trends are discussed as relevant to consumers, producers, health campaign designers, and researchers alike.

Once a target audience and a health behavior of interest are selected for a potential mass media campaign, the next task is selecting beliefs about the health behavior to serve as the basis for campaign message content. For novel health behaviors, such as the use of emerging tobacco products, limited empirical research on beliefs about these behaviors exists. A multimethod approach was applied to generate potential campaign beliefs for emerging behaviors. Three methods were conducted in this investigation in order to generate a list of potential testable campaign beliefs, using youth e-cigarette use as a case study: (1) a search of published and unpublished literature including gathering measures from several national surveys (through 2016), (2) an online elicitation survey (conducted in 2016), and (3) unsupervised topic modeling of media texts (from 2014 to 2015, analyzed in 2016). Details are provided on how each method was employed to both generate and prioritize beliefs related to youth e-cigarette use into a final set of 115 beliefs across 23 belief themes. This multimethod approach can provide four utilities when thinking through a health campaign for novel health behaviors: (1) developing an exhaustive and complementary list of beliefs, (2) generating overarching themes and distilling larger themes into more nuanced beliefs, (3) identifying language most relevant to the target population, and (4) prioritizing beliefs for message pilot testing with members of the target audience.
