Impact of Online Information on Self-Isolation Intention During the COVID-19 Pandemic: Cross-Sectional Study.

BACKGROUND: During the coronavirus disease (COVID-19) pandemic, governments issued movement restrictions and placed areas into quarantine to combat the spread of the disease. In addition, individuals were encouraged to adopt personal health measures such as social isolation. Information regarding the disease and recommended avoidance measures were distributed through a variety of channels including social media, news websites, and emails. Previous research suggests that the vast amount of available information can be confusing, potentially resulting in overconcern and information overload. OBJECTIVE: This study investigates the impact of online information on the individual-level intention to voluntarily self-isolate during the pandemic. Using the protection-motivation theory as a framework, we propose a model outlining the effects of cyberchondria and information overload on individuals' perceptions and motivations. METHODS: To test the proposed model, we collected data with an online survey (N=225) and analyzed it using partial least square-structural equation modeling. The effects of social media and living situation were tested through multigroup analysis. RESULTS: Cyberchondria and information overload had a significant impact on individuals' threat and coping perceptions, and through them on self-isolation intention. Among the appraisal constructs, perceived severity (P=.002) and self-efficacy (P=.003) positively impacted self-isolation intention, while response cost (P<.001) affected the intention negatively. Cyberchondria (P=.003) and information overload (P=.003) indirectly affected self-isolation intention through the aforementioned perceptions. Using social media as an information source increased both cyberchondria and information overload. No differences in perceptions were found between people living alone and those living with their families. CONCLUSIONS: During COVID-19, frequent use of social media contributed to information overload and overconcern among individuals. To boost individuals' motivation to adopt preventive measures such as self-isolation, actions should focus on lowering individuals' perceived response costs in addition to informing them about the severity of the situation.

Access to digital technology among families coming to urban pediatric primary care clinics.

OBJECTIVE: Digital technologies offer new platforms for health promotion and disease management. Few studies have evaluated the use of digital technology among families receiving care in an urban pediatric primary care setting. METHODS: A self-administered survey was given to a convenience sample of caregivers bringing their children to 2 urban pediatric primary care centers in spring 2012. The survey assessed access to home Internet, e-mail, smartphone, and social media (Facebook and Twitter). A "digital technology" scale (0-4) quantified the number of available digital technologies and connections. Frequency of daily use and interest in receiving medical information digitally were also assessed. RESULTS: The survey was completed by 257 caregivers. The sample was drawn from a clinical population that was 73% African American and 92% Medicaid insured with a median patient age of 2.9 years (interquartile range 0.8-7.4). Eighty percent of respondents reported having Internet at home, and 71% had a smartphone. Ninety-one percent reported using e-mail, 78% Facebook, and 27% Twitter. Ninety-seven percent scored ≥1 on the digital technology scale; 49% had a digital technology score of 4. The digital technology score was associated with daily use of digital media in a graded fashion (P < .0001). More than 70% of respondents reported that they would use health care information supplied digitally if approved by their child's medical provider. CONCLUSIONS: Caregivers in an urban pediatric primary care setting have access to and frequently use digital technologies. Digital connections may help reach a traditionally hard-to-reach population.

Internet health information use and e-mail access by parents attending a paediatric emergency department.

OBJECTIVES: To document internet access and health related usage patterns by families of children in a large paediatric emergency department (ED), and to discover if parents want the internet to become a tool for transferring medical test results. METHODS: This was a pre-tested, 21 item, interview conducted with parents at the paediatric ED in Toronto over 3 months. Descriptive statistics and frequency distributions were calculated and variables associated with parents wishing to access results electronically were examined. RESULTS: In total, 950 parents completed the interview (93%), of whom 87% reported routine internet access, 75% reported having an e-mail account, and 60% accessed their e-mail once or more a day. Over half (56%) reported searching the internet for health related information, with 8.5% of these searching immediately preceding their visit. Nearly three quarters (73%) indicated they would like to receive an e-mail containing the results of tests conducted in the ED; 66% of all respondents and 89% of those with e-mail indicated that they would like their child's primary care provider to receive information electronically. CONCLUSION: The majority of families have internet access and most want to receive medical information electronically and to send it to the primary provider. The vast use of internet for health related information emphasises the need to guide parents regarding reliable resources online, possibly as part of their ED visit.

Human dynamics: Darwin and Einstein correspondence patterns.

In an era when letters were the main means of exchanging scientific ideas and results, Charles Darwin (1809-82) and Albert Einstein (1879-1955) were notably prolific correspondents. But did their patterns of communication differ from those associated with the instant-access e-mail of modern times? Here we show that, although the means have changed, the communication dynamics have not: Darwin's and Einstein's patterns of correspondence and today's electronic exchanges follow the same scaling laws. However, the response times of their surface-mail communication is described by a different scaling exponent from e-mail communication, providing evidence for a new class of phenomena in human dynamics.

Digital reference service: trends in academic health science libraries.

Two years after the initial 2002 study, a greater number of academic health science libraries are offering digital reference chat services, and this number appears poised to grow in the coming years. This 2004 follow-up study found that 36 (27%) of the academic health science libraries examined provide digital chat reference services; this was an approximately 6% increase over the 25 libraries (21%) located in 2002. Trends in digital reference services in academic health science libraries were derived from the exploration of academic health science library Web sites and from digital correspondence with academic health science library personnel using e-mail and chat. This article presents an overview of the current state of digital reference service in academic health science libraries.
