Integrating Reasoned Action Approach and Message Sidedness in the Era of Misinformation: The Case of HPV Vaccination Promotion

The influence of national origin cues in HPV vaccination advertising: An eye-tracking study of visual attention and vaccine perception using quantitative and qualitative analysis

This study is among the first to investigate how national origin cues influence visual attention and perception in HPV vaccine advertisements, using eye-tracking technology to provide objective insights into consumer responses. By integrating methods from public health, psychology, and advertising research, this study explores how visual attention is shaped by national affiliation cues. In a controlled experimental setting with a sample of 40 UK university students, we investigated visual attention and effectiveness of HPV vaccination advertisements by comparing ads disclosing the national origin of the vaccine and without any origin information. We assessed total fixation duration and time to first fixation to various elements of the ad, along with intention and attitude measures. Contrary to one of our hypotheses, we did not find significant differences in intention (p = .758) and attitude (p = .620) measures. However, there was significant difference in total fixation duration toward one of the ad images between conditions (p = .043). The qualitative analysis reveals the role of country-of-origin (COO) in HPV vaccination advertising, suggesting a shift in attention from that image to the COO cue. Furthermore, eight out of the 20 participants in the treatment condition did not fixate at the COO cue. Findings provide critical insights for public health communication strategies, suggesting that the use (or omission) of national origin cues in vaccine advertisements could influence vaccine perception and hesitancy. These results highlight the need for strategic messaging approaches to enhance HPV vaccine acceptance and improve public trust in domestic and international vaccines.

The impact of vaccine access difficulties on HPV vaccine intention and uptake among female university students in China

BACKGROUND

Ensuring vaccine access is a prerequisite for promoting human papilloma virus (HPV) vaccination. Although HPV vaccination efforts in China have primarily focused on young females, little research has examined the difficulties they face in accessing the HPV vaccine and its impact on vaccine uptake and intention. This study analyzed the overall perception of access difficulties to HPV vaccines, as well as three specific vaccine access difficulties, and examined their influencing factors among female university students in China. We also examined the associations between overall and specific vaccine access difficulties and HPV vaccination intention and uptake.

METHODS

A cross-sectional study was conducted among female university students from eight universities or colleges in Zhejiang Province, China, from December 2020 to January 2021. Logistic regressions were used to identify factors associated with both overall and specific perceptions of vaccine access difficulties. A multivariable logistic regression model and a multiple linear regression model were used to explore factors influencing HPV vaccine uptake and vaccine intention by controlling for potential confounding factors, respectively.

RESULTS

A total of 3176 female university students were included in this study. The proportion of female students perceiving overall difficulty in obtaining HPV vaccine, as well as difficulties in accessing the desired type of HPV vaccine, HPV vaccination centers, and HPV vaccination information, were 60.6%, 57.7%, 60.7%, and 54.0%, respectively. Perceived overall difficulty in obtaining HPV vaccine, as well as difficulties in accessing the desired type of HPV vaccine, HPV vaccination centers, and HPV vaccination information were associated with HPV vaccine uptake and intention.

CONCLUSIONS

Chinese female university students generally perceived various difficulties in accessing HPV vaccine. It is crucial to improve access to HPV vaccine, optimize the layout and service quality of HPV vaccination centers, and enhance the dissemination and transparency of HPV vaccine information. More efforts are needed to provide a strong guarantee for HPV vaccination uptake among female university students.

Mitigating Health and Science Misinformation: A Scoping Review of Literature from 2017 to 2022

Literature on how to address misinformation has rapidly expanded in recent years. The aim of this scoping review was to synthesize the growing published literature on health and science misinformation mitigation interventions. English-language articles published from January 2017 to July 2022 were included. After title/abstract screening, 115 publications (148 empirical studies) met inclusion criteria and were coded for sample characteristics, topics, mitigation strategies, research methods, outcomes, and intervention efficacy. A marked increase in misinformation mitigation research was observed in 2020-2022. COVID-19, vaccines, and climate change were the most frequently addressed topics. Most studies used general population samples recruited online; few focused on populations most vulnerable to misinformation. Most studies assessed cognitive outcomes (e.g., knowledge), with fewer assessing health behavior, communication behavior, or skills. Correction (k = 97) was the most used misinformation mitigation strategy, followed by education and other literacy initiatives (k = 39) and prebunking/inoculation (k = 24). Intervention efficacy varied, with 76 studies reporting positive, 17 reporting null, and 68 reporting mixed results. Most misinformation mitigation interventions were limited to short-term online experiments focused on improving cognitive outcomes. Priority research areas going forward include expanding and diversifying study samples, scaling interventions, conducting longitudinal observations, and focusing on communities susceptible to misinformation.

Celebrity Identification and Reasoned Action: An Integrative Model of the Relationship Between Media Use and Breast Cancer Screening Intention

This study investigates the relationship between media use and breast cancer screening intentions by integrating the celebrity identification model and the theory of reasoned action. It tests an integrative model with survey data from 315 U.S. adult women. The study found that media use for breast cancer information was positively associated with parasocial interaction (PSI) and identification with celebrities who have or have had breast cancer; PSI was positively associated with attitudes, descriptive and injunctive norms in breast cancer screening, while identification with celebrities was positively associated with descriptive norms; attitudes, injunctive norms and descriptive norms were positively associated with breast cancer screening intentions. The study supports the mediating effect of PSI, identification, attitudes, and descriptive and injunctive norms on the association between media use and breast cancer prevention intentions.

Red media, blue media, and misperceptions: examining a moderated serial mediation model of partisan media use and COVID-19 misperceptions

Misinformation and misperceptions about COVID-19 have undermined democratic system. Partisan media are regarded as one of the culprits for facilitating the spread of misinformation. Grounded in the extended communication mediation model, this study analyzes a U.S. survey sample and examines the conditional indirect effects of partisan media use on COVID-19 related misperceptions. Findings show that using conservative and liberal media both have positive effects on misperceptions and message derogation. Conservative media use has a negative impact on perceived response efficacy, whereas liberal media use positively influenced it. Furthermore, the effect of liberal media use on misperceptions became negative when serially mediated by perceived response efficacy and message derogation. Lastly, discussion network heterogeneity was a significant moderator, such that the indirect effects of partisan media use on misperceptions became weaker among those with a more heterogeneous discussion network. Theoretical and practical implications are discussed.
