Abstract: When numerous reasons behind the obesity problem, such as eating junk food, consuming too many calories, sedentary lifestyle, and other individual-centric causes may not be easily erased, several factors were found to lead people to better healthy eating habits and lifestyles. This study was designed to test a proposed model that consisted of various dynamic factors toward healthy food choice. Results showed that online search for nutrition information was significantly affected by obesity knowledge, but not by BMI. Then, online search for nutrition information would affect healthy food choice, while self-efficacy also promoted healthy food choice. Moreover, online search for nutrition information and self-efficiency jointly yielded a significant impact on healthy food choice. Both practical and theoretical implications were discussed.
Abstract: Successful COVID-19 vaccine promotion for the unvaccinated relies on increasing positive reactions but also reducing negative responses to persuasive messages. The current study examined the relative effects of narrative vs. non-narrative public service announcements (PSAs) promoting COVID-19 vaccination on both positive and negative reactions. We explored the role of empathy and psychological reactance as underlying mechanisms. Results of an experiment involving unvaccinated young adults indicate that the narrative (vs. non-narrative) PSAs led to greater empathy. While no direct effects of message type emerged on psychological reactance or vaccination intention, results of a serial multi-mediator model confirmed that empathy and psychological reactance mediated the effects of message type on vaccination intention, yielding theoretical and practical implications for research and practice in COVID-19 vaccination and health communication.
Abstract: To further investigate the role of conspirational beliefs on health-related behaviors during a health pandemic such as COVID-19, we conducted an online survey among U.S. adults (N = 798) to examine: (1) the strengths of different groups of individual-level variables in predicting conspiracy beliefs about COVID-19 and related health behaviors; and (2) the role of beliefs in conspiracy theories about COVID-19 in mediating the relationship between individual differences and COVID-19 health-related behaviors. Our findings provide implications to pandemic communication theory and practice.
Abstract: Based on a COVID-19 pandemic communication survey (N = 3,124) in Australia, Finland, Italy, South Korea, Sweden, and the United States, our study examined how trust in government sources affects the vaccination intention and how this translates into cross-national variations in the outcome. Our findings revealed that the direct effect of trust in government sources on vaccination intention and the indirect effect via power distance and uncertainty avoidance varied across the six countries.
Abstract: To close existing research gap and combat vaccine hesitancy among young adults, we conduct this study to integrate psychological reactance theory to better understand the effectiveness of three emerging yet understudied emotional appeals (i.e., guilt, shame, and pride) in health risk context. The current research has two goals: (1) to examine how different emotional appeals (guilt vs. shame vs. pride) and user-generated comments toward COVID-19 vaccine messages independently or interactively affect psychological reactance and (2) to understand the mediating role of psychological reactance between emotional appeals and user-generated comments and desired behavioral outcomes. An experimental study with 3 (guilt vs. shame vs. pride) by 2 (positive-valenced comments vs. negative-valenced comments) between-subjects factorial design will be conducted with college students (aged 18-24) at a large public university in the United States. Our findings strengthen the theoretical foundation on how health risk messages with user-generated comments interactively can predict undesired health outcomes. Our study also helps health organizations design more effective messages targeting at young adults by lowering psychological reactance and enhancing persuasive power in motivating COVID-19 vaccination.
Background: The perceived threat of a contagious virus may lead people to be distrustful of immigrants and out-groups. Since the COVID-19 outbreak, the salient politicized discourses of blaming Chinese people for spreading the virus have fueled over 2000 reports of anti-Asian racial incidents and hate crimes in the United States.
Objective: The study aims to investigate the relationships between news consumption, trust, intergroup contact, and prejudicial attitudes toward Asians and Asian Americans residing in the United States during the COVID-19 pandemic. We compare how traditional news, social media use, and biased news exposure cultivate racial attitudes, and the moderating role of media use and trust on prejudice against Asians is examined.
Methods: A cross-sectional study was completed in May 2020. A total of 430 US adults (mean age 36.75, SD 11.49 years; n=258, 60% male) participated in an online survey through Amazon’s Mechanical Turk platform. Respondents answered questions related to traditional news exposure, social media use, perceived trust, and their top three news channels for staying informed about the novel coronavirus. In addition, intergroup contact and racial attitudes toward Asians were assessed. We performed hierarchical regression analyses to test the associations. Moderation effects were estimated using simple slopes testing with a 95% bootstrap confidence interval approach.
Results: Participants who identified as conservatives (β=.08, P=.02), had a personal infection history (β=.10, P=.004), and interacted with Asian people frequently in their daily lives (β=.46, P<.001) reported more negative attitudes toward Asians after controlling for sociodemographic variables. Relying more on traditional news media (β=.08, P=.04) and higher levels of trust in social media (β=.13, P=.007) were positively associated with prejudice against Asians. In contrast, consuming news from left-leaning outlets (β=–.15, P=.001) and neutral outlets (β=–.13, P=.003) was linked to less prejudicial attitudes toward Asians. Among those who had high trust in social media, exposure had a negative relationship with prejudice. At high levels of trust in digital websites and apps, frequent use was related to less unfavorable attitudes toward Asians.
Conclusions: Experiencing racial prejudice among the Asian population during a challenging pandemic can cause poor psychological outcomes and exacerbate health disparities. The results suggest that conservative ideology, personal infection history, frequency of intergroup contact, traditional news exposure, and trust in social media emerge as positive predictors of prejudice against Asians and Asian Americans, whereas people who get COVID-19 news from left-leaning and balanced outlets show less prejudice. For those who have more trust in social media and digital news, frequent use of these two sources is associated with lower levels of prejudice. Our findings highlight the need to reshape traditional news discourses and use social media and mobile news apps to develop credible messages for combating racial prejudice against Asians.
Abstract: Background: African Americans have the highest colorectal cancer (CRC) incidence and mortality rates of any racial/ethnic group and screening rates remain well below the National Colorectal Cancer rountable screening goal of 80%.
Purpose: This randomized trial compared the efficacy of two clinic-based interventions for increasing CRC screening among African American primary care patients.
Conclusions: The computer-tailored intervention was more effective than a non-tailored brochure for increasing completion of SBT and either screening test. Over 26% of participants were screened with either test at 6 months. Computer-tailored interventions can significantly improve CRC screening rates in low-income African Americans, but the impact of a one-time intervention to promote colonoscopy is limited.
Abstract: Scholars have adopted Street’s (2003) ecological model of communication in medical encounters to investigate the factors promoting patient participation in health care. However, factors demonstrated in the ecological model were bounded in the context of medical care primarily focusing on health care providers and patients. Social factors, such as patients’ relationships and supportive communication with others outside the context of health care remain relatively unexplored. To expand the purview of our understanding of factors that influence patient participation, this research integrated social support literature into the research on physician-patient communication and proposed a model which described a process through which social support can enhance patient participation in health care. The data analyzed in this study were a part of two larger clinical trials in which 661 women with breast cancer were recruited from three cancer institutions in the United States. The results from structural equation modeling analysis from cross-sectional and longitudinal data provided strong evidence for the hypotheses predicting that perceived social support was positively associated with health information competence, which in turn fully mediated the association between social support and patient participation in health care. Theoretical and practical implications are discussed.
