Improving rural White men's attitudes toward clinical trial messaging and participation: effects of framing, exemplars and trust.

This study examined whether framing, exemplar presence and exemplar race in social media news posts influence rural White men's perceptions, attitudes and behavioral intentions toward clinical trial participation, and if so, how individual trust in doctors moderates the effects of these three factors. An experiment with a 2 within (framing: cognitive versus psychological barriers) × 2 within (exemplar: present versus absent) × 2 between (exemplar race: White versus Black) subjects mixed factorial design was conducted among rural White men (N = 208). Twelve social media news posts about clinical trial participation were created for the experiment.

Overcoming Black Americans' Psychological and Cognitive Barriers to Clinical Trial Participation: Effects of News Framing and Exemplars.

This study examines how news features (framing and the use of exemplars) can help overcome two common barriers (psychological and cognitive) impeding Black American participation in clinical trials. In an online experiment, Black participants ( = 390) viewed social media news posts varying in framing (focus on psychological vs. cognitive barriers) and use of an exemplar (present vs.

Effects of Communication Source and Racial Representation in Clinical Trial Recruitment Flyers.

The current study was designed to examine effective message strategies that can be employed in designing mediated communication messages to improve clinical trial research participation. In the study, a total of 300 participants completed an online experiment in which they responded to five different clinical trial recruitment advertisements whose information sources varied in their credentials and race. Overall, peer-featured ads in which previous clinical trial participants communicated their prior experience in clinical trial participation, compared to expert-featured ads in which medical doctors communicated information about clinical trials, led to higher message and topic relevance, higher message credibility, more favorable attitudes toward clinical trials, and higher intentions to participate in future clinical trials.

Visualizing science: The impact of infographics on free recall, elaboration, and attitude change for genetically modified foods news.

Within the theoretical frameworks of the dual coding theory, this study examined how the implementation of infographics would influence audiences' cognitive responses to science news reporting topics of genetically modified food and bioengineering. A total of 280 participants were randomly assigned to view news articles that report genetically modified food information presented via infographics or text. Findings showed that the participants recalled more information, elaborated more message-relevant thoughts, and had more favorable attitude changes toward the genetically modified foods when science news content is presented in infographics compared with text.

This study examined how genetically modified (GM) food news' presentation - text-only, addition of photographs, or addition of infographics - can affect risk perception and attitude towards GM foods. Further, individuals' healthy eating involvement and perceived threat to GM foods were considered as individual difference variables influencing the level of perceived relevance to the GM food news.

Foundations of Arrogance: A Broad Survey and Framework for Research.

We consider the topic of from a cross-disciplinary viewpoint. To stimulate further research, we suggest three types of arrogance (individual, comparative, and antagonistic) and six components contributing to them, each logically related to the next. The components progress from imperfect knowledge and abilities to an unrealistic assessment of them, an unwarranted attitude of superiority over other people, and related derisive behavior.
