Overcoming Resistance Through Narratives: Findings from a Meta-Analytic Review

Abstract: To understand the mechanisms underlying narrative persuasion, a growing body of theoretical and empirical work suggests that narratives reduce audience resistance, possibly via narrative engagement. To synthesize this research, we performed a two-part metaanalysis using three-level random-effects models. Part I focused on experimental studies that directly compared narratives and non-narratives on resistance. Based on 15 effect sizes from nine experimental studies, the overall effect size was d = −.213 (equivalent r = −.107; p < .001), suggesting that narratives generated less resistance than nonnarratives. Part II was a synthesis of studies of the relationship between narrative engagement and resistance, consisting of 63 effect sizes from 25 studies. Narrative engagement and resistance were negatively correlated (r = −.131; p < .001), and this relationship was moderated by narrative message characteristics, including genre, length, medium, and character unit. Implications of our findings and directions for future research are discussed.

Assessing Genetic Literacy Awareness and Knowledge Gaps in the US Population: Results from the Health Information National Trends Survey.

Abstract: Background/Aims: Public understanding of the role of genetics in disease risk is key to appropriate disease prevention and detection. This study assessed the current extent of awareness and use of genetic testing in the US population. Additionally, the study identified characteristics of subgroups more likely to be at risk for low genetic literacy. Methods: The study used data from the National Cancer Institute’s 2017 Health Information National Trends Survey, including measures of genetic testing awareness, genetic testing applications and genetic testing usage. Multivariable logistic regression models estimated associations between sociodemographics, genetic testing awareness, and genetic testing use. Results: Fifty-seven percent of respondents were aware of genetic tests. Testing awareness differed by age, household income, and race/ethnicity. Most participants had heard of using tests to determine personal disease risk (82.58%) or inherited disease risk in children (81.41%), but less were familiar with determining treatment (38.29%) or drug efficacy (40.76%). Among those with genetic testing awareness, actual testing uptake was low. Conclusions: A large portion of the general public lacks genetic testing awareness and may benefit from educational campaigns. As precision medicine expands, increasing public awareness about genetic testing applications for disease prevention and treatment will be important to support population health.

Characterizing Reactance in Communication Research: A Review of Conceptual and Operational Approaches:

Abstract: Psychological reactance, or simply reactance, has become a major concept of interest in communication research. Although this spike in scholarly attention has greatly advanced our understanding of ...

Persuasive impact of loss and gain frames on intentions to exercise: A test of six moderators

Abstract: The current study situated loss/gain-framing research in the extended parallel process model and tested whether two message features (dose, efficacy appeals) and four individual difference variables (walking self-efficacy, grit, consideration of future consequences, health information overload (HIO)) moderated the impact of message framing on intentions to engage in physical activity. Adults (N = 341, Mage = 38.09, SD = 10.94) were randomly assigned to one of eight message conditions advocating exercise behavior. All four individual difference variables significantly moderated framing effects such that gain-framed messages were more effective for individuals with lower walking self-efficacy, grit, and consideration of future consequences and loss-framed messages were significantly more effective for individuals with higher walking self-efficacy, grit, consideration of future consequences, and for those with lower HIO.

Strategic vision for improving human health at The Forefront of Genomics.

Abstract: Starting with the launch of the Human Genome Project three decades ago, and continuing after its completion in 2003, genomics has progressively come to have a central and catalytic role in basic and translational research. In addition, studies increasingly demonstrate how genomic information can be effectively used in clinical care. In the future, the anticipated advances in technology development, biological insights, and clinical applications (among others) will lead to more widespread integration of genomics into almost all areas of biomedical research, the adoption of genomics into mainstream medical and public-health practices, and an increasing relevance of genomics for everyday life. On behalf of the research community, the National Human Genome Research Institute recently completed a multi-year process of strategic engagement to identify future research priorities and opportunities in human genomics, with an emphasis on health applications. Here we describe the highest-priority elements envisioned for the cutting-edge of human genomics going forward-that is, at 'The Forefront of Genomics'.
