Background: This study assessed psychosocial predictors of U.S. adults' willingness to get a future COVID-19 vaccine and whether these predictors differ under an emergency use authorization (EUA) release of the vaccine. Methods: A survey of 788 U.S. adults was conducted to explore the relationships between demographics and psychosocial predictors of intent to get a future COVID-19 vaccine as well as willingness to get such a vaccine under EUA. Results: Significant predictors of COVID-19 vaccine uptake intentions were education, having insurance, scoring high on subjective norms, a positive attitude toward the vaccine, as well as high perceived susceptibility to COVID-19, high perceived benefits of the vaccine, scoring low on barriers to the vaccine, and scoring high on self-efficacy. Predictors of willingness to take a COVID-19 vaccine under EUA were age, race/ethnicity, positive subjective norms, high perceived behavioral control, positive attitudes toward the vaccine, as well as high perceived susceptibility to COVID-19, high perceived benefits of the vaccine, low barriers to the vaccine, and scoring high on self-efficacy for getting the vaccine. Concerns about rushed vaccine development appear to reduce vaccine uptake intent, as well as willingness to get the vaccine under EUA. Conclusions: COVID-19 vaccine-related messages should both address concerns about the vaccine and its development and reinforce benefits of the vaccine (both factors significant in both models). Vaccine efforts may need to go beyond just communications campaigns correcting misinformation about a COVID-19 vaccine to also focus on re-establishing public trust in government agencies.
BackgroundThere is often a lack of transparency in research using online panels related to recruitment methods and sample derivation. The purpose of this study was to describe the recruitment and participation of respondents from two disparate surveys derived from the same online research panel using quota sampling.
MethodsA commercial survey sampling and administration company, Qualtrics, was contracted to recruit participants and implement two internet-based surveys. The first survey targeted adults aged 50-75 years old and used sampling quotas to obtain diversity with respect to household income and race/ethnicity. The second focused on women aged 18-49 years and utilized quota sampling to achieve a geographically balanced sample.
ResultsA racially and economically diverse sample of older adults (n=419) and a geographically diverse sample of younger women (n=530) were acquired relatively quickly (within 12 and 4 days, respectively). With exception of the highest income level, quotas were implemented as requested. Recruitment of older adults took longer (vs. younger female adults). Although survey completion rates were reasonable in both studies, there were inconsistencies in the proportion of incomplete survey responses and quality fails.
ConclusionsCancer researchersand researchers in generalshould consider ways to leverage the use of online panels for future studies. To optimize novel and innovative strategies, researchers should proactively ask questions about panels and carefully consider the strengths and drawbacks of online survey features including quota sampling and forced response.
ImpactResults provide practical insights for cancer researchers developing future online surveys and recruitment protocols.
The public increasingly searches for and discusses health information online, but few studies have examined breast cancer–related posts on visual social media platforms. To shed light on cancer-focused posts on the visual social media platform Pinterest, this study analyzed a random sample of 476 breast cancer–related posts (also referred to as “pins”). Using a quantitative content analysis, pins were coded for type of visual and textual information included and user engagement with pins (i.e., frequency of repins and comments). This novel research supports the current use and potential future utility of Pinterest as a venue for health communication related to breast cancer. Study results have important implications for the development of future health promotion programs on Pinterest aimed at reducing breast cancer risk among women.
Waterpipe tobacco is among the most rapidly growing trends in tobacco smoking, the growing use and acceptance of which are taking place at a time when cigarette smoking is regarded in an increasingly negative manner (Martinasek, McDermott, & Martini, 2011). Given the health risks and the misperceptions associated with waterpipe smoking, this study focuses on how waterpipe smoking is portrayed and represented on the social media platform Pinterest. In total, 800 Pinterest pins were content analyzed. The vast majority of the sampled pins were primarily image based. More than half of the pins linked to a website external to Pinterest that often redirected the pinner to a commercial website. Waterpipe-focused pins portrayed waterpipe smoking more in a positive light than in a negative light, and conveyed a sense of pleasure, aesthetic, and relaxation, which tended to trigger more repins, likes, and higher levels of engagement. Overall, the risks of waterpipe smoking were not represented on Pinterest, indicating that the social media portrayal of waterpipe smoking needs improvement and could benefit from a public health perspective.
We analyzed Instagram posts about Zika by using the Health Belief Model. We found a high presence of threat messages, yet little engagement with these posts. Public health professionals should focus on posting messages to increase self-efficacy and benefits of protective behavior, especially when a vaccine becomes available.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
