Clinical and Family Conversations Regarding Genetic Testing
This study compares content in clinical and family interactions in the context of cancer-related genetic testing (CGT) of a patient with ovarian cancer. The sample was taken as an extreme instance from a larger study, representing participants in a situation with substantial uncertainty. Participants include a genetic counselor, a patient diagnosed with ovarian cancer who received a variant of uncertain significance (VUS) result, and her adult fa…
Exploring Sentiment, Values, and Misinformation Surrounding Vaccination Legislation on Twitter
California remains among a handful of U.S. states with no clause for a personal belief exemption for required vaccines due to passage of SB277. As vaccines represent an important tool in the public health arsenal against SARS-CoV-2 and may yet be required by schools and employers, other states may consider enacting laws similar to SB277 to address COVID-19 and future outbreaks of infectious diseases. In this case study of California’s SB277 bill,…

Improving perceptions of oral health importance and encouraging dental visits could enable increased oral hygiene behaviors among young Mexican-American identifying adults
The Association between Message Framing and Intention to Vaccinate Predictive of Hepatitis A Vaccine Uptake
As ongoing, sporadic outbreaks of hepatitis A virus (HAV) infections present public health challenges, it is critical to understand public perceptions about HAV, especially regarding vaccination. This study examines whether message framing changes the intention to vaccinate against HAV and self-reported vaccine behavior. Using a randomized controlled trial (N = 472) in February 2019 via Amazon Mechanical Turk, participants were randomized to one …
Information Scanning Impacts Nonmedical Drug Use Among College Students
Health information that is acquired through information scanning has been shown to play an important role in shaping individual beliefs and health behavior. This study examines the direct and indirect effects of the breadth of scanning from media and interpersonal sources about two risk behaviors (nonmedical use of amphetamines and marijuana) on subsequent drug use behavior through changes to perceived norms. We test effects of scanning using a l…
Covid-19, Genetics, and Risk
The COVID-19 pandemic represented a unique information seeking and sharing context for billions of Internet users across the globe. Although previous research has established that people often seek health information on the Internet, including through social media platforms, there was a political element to pandemic responses that is not typical of health issues such as seasonal influenza or heart conditions. This unique context, in conjunction w…
Dual Process Models and Information Engagement
This study uses a three-wave prospective longitudinal survey (at 6-month intervals) to test effects of information seeking and scanning on attitudes toward marijuana among college students in Israel (N = 700). We integrate constructs from the elaboration likelihood model to contrast processes of attitude change among individuals who vary in moderators of information processing depth (motivation and ability). In addition, we test whether trust in …
Examining Vaccine Sentiment on Twitter and Local Vaccine Deployment during the Covid-19 Pandemic
Understanding local public attitudes toward receiving vaccines is vital to successful vaccine campaigns. Social media platforms may help uncover vaccine sentiments during infectious disease outbreaks at the local level, and whether offline local events support vaccine-promotion efforts. Communication Infrastructure Theory (CIT) served as a guiding framework for this case study of the San Diego region examining local public sentiment toward vaccin…
“I Definitely Did Not Report It When I Was Raped . . . #WeBelieveChristine #MeToo”
The “Me Too” movement, founded by activist Tarana Burke, began in 2006, before Twitter became the viral platform for political activism and news media that it is known for today. The reemergence of the Me Too movement on Twitter in 2017 sparked a widespread focus on the societal issue of sexual misconduct. This study examines sexual assault disclosures as an aspect of such misconduct through the context of the Me Too movement on Twitter. Through …
Twitter Communication During an Outbreak of Hepatitis A in San Diego, 2016–2018
Objectives. To examine how and what information is communicated via social media during an infectious disease outbreak. Methods. In the context of the 2016 through 2018 hepatitis A outbreak in San Diego County, California, we used a grounded theory–based thematic analysis that employed qualitative and quantitative approaches to uncover themes in a sample of public tweets (n = 744) from Twitter, a primary platform used by key stakeholders to commu…
Measures of Information Seeking
Health information is readily available and easily obtained from a variety of media and interpersonal sources. Although several studies have examined health-related information seeking, a comprehensive validation study of this measure is still needed. This study uses a longitudinal cohort study of Israeli university students (N = 800) aged 18–30, and a cross-sectional sample of U.S. college students (N = 498) to validate measures of information s…
