Modeling Electronic-Cigarette Users' Risk Information Avoidance.

The current study examined e-cigarette users' risk information avoidance (i.e., RIA), which is a significant challenge to e-cigarette risk communication. Applying and extending previous RIA studies and the risk information seeking and processing (RISP) model, this study identified the predictors of e-cigarette users' RIA with a comprehensive model that incorporated new roles for scientific uncertainty and relevant channel beliefs. Responses collected from an online survey were analyzed (N = 593) and support was found for two pathways that explain e-cigarette users' motivation for RIA. One suggests heightened risk perceptions were associated with strong negative affective responses that include fear, anger, sadness, and guilt. These affective responses, in turn, were positively associated with RIA intentions. The second was a direct, positive association between scientific uncertainty and RIA as well as an indirect path mediated by relevant channel beliefs. More specifically, scientific uncertainty was negatively associated with quality perceptions of e-cigarette information making it more likely e-cigarette users would avoid it. Suggestions for how to prevent or mitigate these processes that result in e-cigarette users' maladaptive response of RIA are discussed.

An Auti-Sim Intervention: The Role of Perspective Taking in Combating Public Stigma with Virtual Simulations.

Public stigma associated with autism spectrum disorder (ASD) commonly stems from judgments surrounding sensory overload symptoms. As individuals try and make sense of observed disordered behaviors of those with ASD, they are quick to develop dispositional attributions instead of acknowledging situational instigators. Interventions aimed at educating the lay public that disordered actions are a result of a biological causes have been successful in lessening perceptions of responsibility, yet foster an out-group perspective allowing prejudice attitudes and discriminatory behaviors to persist. The present study examines the short-term effectiveness of engagement with a virtual simulation, Auti-Sim, to combat stigma by giving lay people a first-person experience of sensory overload. To assess Auti-Sim, a between-subject, in-laboratory experimental design was employed. A total of 123 undergraduate students were randomly assigned to 1 of 3 interventions (virtual simulation engagement, observation of simulation engagement, or reading text vignettes). Participants completed a brief pretest questionnaire, encountered the intervention, and then completed a post-test questionnaire. Engagement with the virtual simulation resulted in heightened perspective taking, which subsequently increased emotional concern, helping intentions, and willingness to volunteer compared with the observation only or text vignette intervention. Positive attitudes toward those with ASD did not differ across interventions. Fostering a different understanding of disordered action through a virtual simulation has the potential to elicit perspective taking and subsequent empathetic outcomes. Perspective taking seems to encourage perceptions of in-group belonging rather than out-group categorization and thus might be a desired outcome for stigma-reducing efforts.

Linguistic Strategies for Improving Informed Consent in Clinical Trials Among Low Health Literacy Patients.

Background: Improving informed consent to participate in randomized clinical trials (RCTs) is a key challenge in cancer communication. The current study examines strategies for enhancing randomization comprehension among patients with diverse levels of health literacy and identifies cognitive and affective predictors of intentions to participate in cancer RCTs. Methods: Using a post-test-only experimental design, cancer patients (n = 500) were randomly assigned to receive one of three message conditions for explaining randomization (ie, plain language condition, gambling metaphor, benign metaphor) or a control message. All statistical tests were two-sided. Results: Health literacy was a statistically significant moderator of randomization comprehension (P = .03). Among participants with the lowest levels of health literacy, the benign metaphor resulted in greater comprehension of randomization as compared with plain language (P = .04) and control (P = .004) messages. Among participants with the highest levels of health literacy, the gambling metaphor resulted in greater randomization comprehension as compared with the benign metaphor (P = .04). A serial mediation model showed a statistically significant negative indirect effect of comprehension on behavioral intention through personal relevance of RCTs and anxiety associated with participation in RCTs (P < .001). Conclusions: The effectiveness of metaphors for explaining randomization depends on health literacy, with a benign metaphor being particularly effective for patients at the lower end of the health literacy spectrum. The theoretical model demonstrates the cognitive and affective predictors of behavioral intention to participate in cancer RCTs and offers guidance on how future research should employ communication strategies to improve the informed consent processes.

Selective perceptions of hydraulic fracturing.

Hydraulic fracturing (HF) is a focal topic in discussions about domestic energy production, yet the American public is largely unfamiliar and undecided about the practice. This study sheds light on how individuals may come to understand hydraulic fracturing as this unconventional production technology becomes more prominent in the United States. For the study, a thorough search of HF photographs was performed, and a systematic evaluation of 40 images using an online experimental design involving N = 250 participants was conducted. Key indicators of hydraulic fracturing support and beliefs were identified. Participants showed diversity in their support for the practice, with 47 percent expressing low support, 22 percent high support, and 31 percent undecided. Support for HF was positively associated with beliefs that hydraulic fracturing is primarily an economic issue and negatively associated with beliefs that it is an environmental issue. Level of support was also investigated as a perceptual filter that facilitates biased issue perceptions and affective evaluations of economic benefit and environmental cost frames presented in visual content of hydraulic fracturing. Results suggested an interactive relationship between visual framing and level of support, pointing to a substantial barrier to common understanding about the issue that strategic communicators should consider.

Impacts of efficacy and exemplification in an online message about weight loss on weight management self-efficacy, satisfaction, and personal importance.

Health information search is among the most popular Internet activities, requiring health campaigns to attract attention in a context of unprecedented competition with alternative content. The present study reconstructs a similar context that allows selective avoidance and exposure in order to examine which health message characteristics foster particular message impacts. Drawing on social cognitive theory, a 3-session study examined short-term and delayed impacts of efficacy and exemplification as characteristics of a weight loss online message, offered for selective reading among other content, on weight management self-efficacy, satisfaction, and personal importance. Short-term impacts and impacts 2 weeks after exposure reflect that the high-efficacy exemplar version increased self-efficacy and satisfaction, while the high-efficacy base-rate version lowered them. However, the exemplar and base-rate versions of the low-efficacy message increased importance of body weight management.

A serial mediation model of message framing on intentions to receive the human papillomavirus (HPV) vaccine: revisiting the role of threat and efficacy perceptions.

Previous research has yielded mixed findings regarding the potential for message framing to influence HPV vaccine-related intentions. Drawing on the Extended Parallel Process Model (EPPM), the current study focuses on the role of threat and efficacy as serial mediators linking message framing and HPV vaccine-related intentions. College-age females and their parents participated in a between-subjects, posttest only experiment to investigate whether behavioral intentions to talk to a doctor about the HPV vaccine differ as a function of framing messages in terms of disease prevention. For young women, framing messages as preventing genital warts (as compared to cancer prevention) significantly increased perceptions of self-efficacy, which enhanced response efficacy perceptions that, in turn, increased intentions to talk to a doctor about the HPV vaccine. There were no effects of message framing among parents. However, response efficacy was a significant mediator of self-efficacy and behavioral intentions for both the college-age females and their parents. The results of this study suggest new approaches for considering the relationship among EPPM constructs.
