Procedures and randomization
Participants were invited to complete a brief screening survey, advertised on Prolific, to determine trial eligibility. To maximize sample representativeness (and account for a proportionally higher number of young adults on the Prolific platform), separate screening adverts were created for males and females, with each being stratified further into two age groups (18–25 years, and ≥26). This ensured that ~10% of screened individuals would be in the 18–25 age group, which is broadly consistent with the general UK population (based on UK Census data, 2011).All eligible individuals were invited to complete a baseline survey (All surveys were hosted on Qualtrics (
