Psychological inoculation protects against the social media infodemic.

Misinformation can have a profound detrimental impact on populations' wellbeing. In this large UK-based online experiment (n = 2430), we assessed the performance of false tag and inoculation interventions in protecting against different forms of misinformation ('variants'). While previous experiments have used perception- or intention-based outcome measures, we presented participants with real-life misinformation posts in a social media platform simulation and measured their engagement, a more ecologically valid approach. Our pre-registered mixed-effects models indicated that both interventions reduced engagement with misinformation, but inoculation was most effective. However, random differences analysis revealed that the protection conferred by inoculation differed across posts. Moderation analysis indicated that immunity provided by inoculation is robust to variation in individuals' cognitive reflection. This study provides novel evidence on the general effectiveness of inoculation interventions over false tags, social media platforms' current approach. Given inoculation's effect heterogeneity, a concert of interventions will likely be required for future safeguarding efforts.

Determinants of nurse's and personal support worker's adherence to facial protective equipment in a community setting during the COVID-19 pandemic in Ontario, Canada: A pilot study.

BACKGROUND: Appropriate and consistent facial protective equipment (FPE) use is critical for preventing respiratory illness transmission. Little is known about FPE adherence by home care providers. The purpose of this study is to adapt an existing facial protection questionnaire and use it to develop an initial understanding of factors influencing home care providers' adherence to FPE during the COVID-19 pandemic. METHODS: A survey was shared with home care providers during Wave 2 of the COVID-19 pandemic in Ontario. Descriptive statistics and logistic regression by FPE adherence were conducted across individual, organizational, and environmental factors. RESULTS: Of the 199 respondents (140 personal support workers; 59 nurses), 71% reported that they always used FPE as required, with greater adherence to masks (89%) than eye protection (73%). The always-adherent reported greater perceived FPE efficacy, knowledge of recommended use and perceived occupational risk, lower education, and not experiencing personal barriers (including difficulty seeing, discomfort, communication challenges). DISCUSSION: Adherence rates were relatively high. In this context, with participants reporting high levels of organizational support, individual-level factors were the significant predictors of adherence. CONCLUSIONS: Initiatives addressing perceived FPE efficacy, knowledge of recommended use, perception of at-work risk, and personal barriers to use may improve FPE adherence.
