Understanding the Political Frames of the Opioid Crisis: A Content Analysis of U.S. Senators' Tweets.

The opioid epidemic in the United States is a public health emergency that has triggered calls to action for policy reforms. However, variations exist between political parties and policymakers on how this issue is communicated to the public. With the substantial growth in the use of social media by policymakers as a tool for disseminating policy-related information affecting their constituents, examining their communication strategies on public health emergency issues is imperative. To better understand how U.S. Senate members use Twitter (now known as X) to communicate opioid-related issues, we conducted a quantitative content analysis of their opioid-related tweets ( = 697) from January 1 to August 25 2022. Findings reveal a significant political divide regarding how senators characterize the opioid crisis, influencing user engagement on Twitter. Guided by the moral foundation theory, the results suggest that Democratic senators were more likely to employ care/harm or fairness/cheating moral foundations, relative to Republican senators, who used more loyalty/betrayal or authority/subversion. Additionally, Democratic senators framed the opioid crisis as a health or policy issue, relative to Republican senators' immigration/border frame. For inclusion of information sources, Democratic senators included significantly more health sources compared to Republican senators' use of media or law enforcement sources. Issue frame and source type significantly influenced user engagement in the form of likes and retweets. These findings provide both practical and theoretical implications.
