    To examine SARS-CoV-2 vaccine confidence, attitudes and intentions in Australian adults as part of the iCARE Study. Design and setting Cross-sectional online survey conducted when free COVID-19 vaccinations first became available in Australia in February 2021. Participants Total of 1166 Australians from general population aged 18–90 years (mean 52, SD of 19).

    How well do covariates perform when adjusting for sampling bias in online COVID‑19 research? Insights from multiverse analyses
    (Springer Nature (Alemania; Reino Unido), 2022) Joyal Desmarais, Keven; Stojanovic, Jovana; Kennedy, Eric B.; Enticott, Joanne C.; Gosselin Boucher, Vincent; Vo, Hung; Košir, Urška; Lavoie, Kim L.; Bacon, Simon L.; Losada, Analía Verónica; iCARE Study Team (Canadá)
    COVID-19 research has relied heavily on convenience-based samples, which—though often necessary—are susceptible to important sampling biases. We begin with a theoretical overview and introduction to the dynamics that underlie samplingbias. We then empirically examine sampling bias in online COVID-19 surveys and evaluate the degree to which common statistical adjustments for demographic covariates successfully attenuate such bias. This registered study analysed responses to identical questions from three convenience and three largely representative samples (total N=13,731) collected online in Canada within the International COVID-19 Awareness and Responses Evaluation Study (www.icarestudy.com). We compared samples on 11 behavioural and psychological outcomes (e.g., adherence to COVID-19 prevention measures, vaccine intentions) across three time points and employed multiverse-style analyses to examine how 512 combinations of demographic covariates (e.g., sex, age, education, income, ethnicity) impacted sampling discrepancies on these outcomes. Signifcant discrepancies emerged between samples on 73% of outcomes. Participants in the convenience samples held more positive thoughts towards and engaged in more COVID-19 prevention behaviours. Covariates attenuated sampling diferences in only 55% of cases and increased diferences in 45%. No covariate performed reliably well. Our results suggest that online convenience samples may display more positive dispositions towards COVID-19 prevention behaviours being studied than would samples drawn using more representative means. Adjusting results for demographic covariates frequently increased rather than decreased bias, suggesting that researchers should be cautious when interpreting adjusted fndings. Using multiversestyle analyses as extended sensitivity analyses is recommended.

    Impact of biological sex and genderrelated factors on public engagement in protective health behaviours during the COVID-19 pandemic : cross-sectional analyses from a global survey
    (BMJ Publishing Group (Reino Unido), 2022) Dev, Rubee; Raparelli, Valeria; Bacon, Simon L.; Lavoie, Kim L.; Pilote, Louise; Norris, Colleen M.; Losada, Analía Verónica; iCARE Study Team (Canadá); GOING-FWD Consortium (Canadá)
    Given the main objective of this study was to examine whether sex and gender-related factors were associated with the public’s adherence to COVID-19-recommended protective health behaviours. Design This was a retrospective analysis of the survey that captured data on people’s awareness, attitudes and behaviours as they relate to the COVID-19 policies. Setting Data from the International COVID-19 Awareness and Responses Evaluation survey collected between March 2020 and February 2021 from 175 countries. Participants Convenience sample around the world.

    Understanding national trends in COVID-19 vaccine hesitancy in Canada : results from five sequential crosssectional representative surveys spanning April 2020–March 2021
    (BMJ Publishing Group (Reino Unido), 2022) Lavoie, Kim L.; Gosselin Boucher, Vincent; Stojanovic, Jovana; Gupta, Samir; Gagné, Myriam; Joyal Desmarais, Keven; Séguin, Katherine; Sheinfeld Gorin, Sherri; Ribeiro, Paula; Voisard, Brigitte; Vallis, Michael; Corace, Kimberly; Presseau, Justin; Bacon, Simon L.; iCARE Study Team (Canadá)
    To examine rates of vaccine hesitancy and their correlates among Canadian adults between April 2020 and March 2021. Design Five sequential cross-sectional age, sex and province-weighted population-based samples who completed online surveys. Setting Canada. Participants A total of 15 019 Canadians aged 18 years and over were recruited through a recognised polling firm (Leger Opinion). Respondents were 51.5% female with a mean age of 48.1 (SD 17.2) years (range 18–95 years) and predominantly white (80.8%).
