To assess respondent attitudes regarding tweet credibility, 
we adapted items used to evaluate Twitter posts first used 
by Vraga and Bode (2017a, b). After viewing each tweet, 
respondents were asked to evaluate the tweet as being use-
ful, interesting, trustworthy, credible, biased, accurate, or 
relevant using a 5-point Likert-type scale. Additionally, 
respondents were asked to indicate how they would inter-
act with the tweet by responding to four questions to gauge 
likely behaviors in regard to the tweet. These behaviors 
included following the Twitter account, retweeting the tweet, 
liking the tweet, and searching for additional information 
related to the tweet.
