DESENSITIZATION TO FEAR-INDUCING COVID-19 HEALTH NEWS ON TWITTER: OBSERVATIONAL
STUDY
JMIR INFODEMIOLOGY 2021;1(1):E26876
URL: HTTPS://INFODEMIOLOGY.JMIR.ORG/2021/1/E26876
DOI: 10.2196/26876
Background
u Early on, the pandemic brought extreme behaviors
aimed at reducing COVID transmission (e.g., panic
buying toilet paper)
u Later, the public began to violate public safety
measures.
u Two considerations arise:
u fear-eliciting health messages elicit motivation to
act
u repeated exposure to these messages result in
desensitization
u We examine the effect of fear-inducing news
articles on people’s expression of anxiety on
Twitter.
u Additionally, we investigate desensitization to the
fear-inducing health news over time, despite the
steadily rising COVID-19 death toll.
Data Collection
u This study examined the anxiety levels
in news articles (n=1,465) and
corresponding user tweets containing
COVID-19 related key terms from Jan 1-
Dec 2, 2020.
u Then we correlated that information
with the death toll of COVID-19 in the
United States at the time each Tweet
was posted.
Statistical Analysis
u We employed a zero-inflated model
utilizing a gamma distribution with a log
link to examine any association between
article anxiety and death toll, along with
their interaction with subsequent tweet
anxiety for all values of tweet anxiety
greater than 0.
u We paired that with a model that used a
binomial distribution with a logit link to
determine 0 anxiety vs. not-0 anxiety in
tweets.
u We recoded the death toll into
categories reflecting death count at the
2nd quartile, the 3rd quartile, and the
4th quartile relative to the 1st quartile.
These values were then used in place of
the continuous variable to model the
interaction.
