The effect of enhanced messaging on COVID-19 testing intentions and behaviour dataset

University of Sydney

Dataset description

This dataset includes 1527 participants (from 18 to 39 years old, both males and females) receiving 2 audio-visual interventions addressing common COVID-19 testing barriers for people with lower health literacy. Participants were recruited from New South Wales, Australia into this randomised controlled trial. Anonymous quantitative data on outcomes for each group including the intention to undergo testing for COVID-19 if symptomatic, intentions about other prevention behaviours (self-isolation if symptomatic, social distancing of 1.5 m, washing hands regularly, and wearing masks in crowded indoor areas), understanding of messaging, risk perceptions, social stigma, and self-efficacy (ie, confidence in overcoming perceived barriers to testing) is included in this dataset. The file type is .XLS.
