Facebook's shared articles on HPV vaccination: analysis of persuasive strategies.

BACKGROUND: The current study analyzed articles shared on Facebook between 2019 and 2021 that discuss the HPV vaccine. Results address a gap in knowledge about the persuasive strategies used in HPV vaccine discourse on Facebook. METHODS: Using Buzzsumo.com, we collected 138 articles, shared on Facebook between 2019 and 2021, with the highest "engagement scores," or total number of reactions, comments, and shares. Using a content analysis methodology, three independent coders were trained in using the study codebook, achieved acceptable inter-rater reliability (Krippendorf's alpha = 0.811), and coded each article in Atlas.ti. RESULTS: Seventy-two articles had a positive valence toward the HPV vaccine, 48 had a negative valence, and 18 were mixed-valence or neutral. Pro-vaccine articles presented a variety of evidence types in support of benefits of HPV vaccination. Pro-vaccine articles primarily originated from national and local news sources. Anti-vaccine articles combined presentation of evidence with persuasive arguments and strategies, such as mistrust of institutions, fear appeals, ideological appeals, presenting a high number of arguments or detail, and minimizing the severity of HPV. Three sources were responsible for producing 62.5% of all anti-vaccine articles in the dataset. Mixed-valence or neutral articles mixed cancer prevention discourse with ideological appeals about protecting parental rights, and were mostly produced by local news outlets. CONCLUSION: The results of this study can help health communicators anticipate the types of discourses that vaccine-hesitant parents may have encountered online. Implications and suggestions for practice are discussed.

HPV vaccine-related articles shared on Facebook from 2019 to 2021: Did COVID make a difference?

Objective: HPV vaccination is recommended for children beginning at age 9 to prevent several types of cancer. Many parents turn to Facebook for health information. This study describes changes in HPV vaccine-related articles shared on Facebook amidst the COVID-19 pandemic. Methods: HPV-related articles shared on Facebook (2019-2021) were collected using Buzzsumo, a social media analytics tool and analyzed using content analysis. Articles were categorized by valence, misinformation, evidence types, persuasive tactics, and framing. We quantified these data and tested for difference by article year. Results: Of the 138 included articles, 51% had positive valence towards the vaccine and 36% had negative valence. In 2021, there was a significant increase in positive messaging (72% vs. 44% in 2019/2020; p < 0.01) and misinformation decreased from 50% in 2019 to 24% in 2021 (p = 0.04). Persuasive strategies were more common in 2019 than in later years. Conclusion: Despite decreased engagement in 2021, more positive HPV vaccine messaging was observed, although a quarter of articles still contained misinformation. Our results can inform strategies for communicating with parents about the HPV vaccine. Innovation: Our study is the first to analyze HPV-related articles linked on Facebook and to assess for differences during the pandemic.

Forensic Nurses' Understanding of Emergency Contraception Mechanisms: Implications for Access to Emergency Contraception.

BACKGROUND: An estimated 25,000 pregnancies result from sexual assault in the United States annually. Numerous professional healthcare organizations endorse offering emergency contraception (EC) as an integrated aspect of post-sexual-assault care. Lack of knowledge surrounding EC's mechanism of action, including misinterpreting ECs as abortifacients, might restrict patient access to this important healthcare option. PURPOSE: We evaluated sexual assault nurse examiners' understanding of the mechanism of action of oral ECs levonorgestrel (LNG) and ulipristal acetate (UPA). METHODS: A cross-sectional survey of practicing sexual assault nurse examiners was conducted through the International Association of Forensic Nurses. RESULTS: Among 173 respondents, 96.53% reported they prescribed/dispensed EC at the time of medical forensic examinations. LNG was prescribed more frequently than UPA (57.80% vs. 38.2%, respectively). When asked if they agreed or disagreed if LNG and UPA can disrupt an established pregnancy, 83.2% selected disagree/strongly disagree for LNG versus 78.6% for UPA, which were not significantly different. When asked whether the Supreme Court ruling overturning Roe v. Wade would change their EC prescribing, 79.77% reported it will have no change, 6.94% said it would increase, and 12.72% reported they were unsure. Several commented they were concerned whether state laws would prohibit EC and at least one program stopped prescribing EC because of their state laws. IMPLICATIONS: Addressing misinformation regarding EC's mechanism of action and increasing access to oral EC options after sexual assault have the potential to reduce the incidence of rape-related pregnancy.
