Procedure
RECRUITMENT
The study used an experimental design and recruited participants through opportunity sampling. Recruitment methods included social media (e.g. Facebook, Instagram, LinkedIn), posters placed around the University campus and through word of mouth. Digital and paper advertisements contained a QR code for participants to access study information and a consent form. Once participants had provided informed consent, they completed baseline measures housed in the Gorilla Experiment Builder. Participants were then randomly assigned 1:1 to either the nature or urban condition using the Gorilla randomizer node. This process is automatic and not influenced by the researchers. Participants were shown a brief, 6-min video of either a nature or urban setting and were presented with an attention check question to measure adherence. Participants were then asked to complete the post-experiment self-report battery. At the end of the study, participants were given a full debrief of the study aims and were invited to be kept updated with the study results. Signposting to mental health services was also provided. Lastly, participants were automatically entered into a prize draw for the chance to win one of three possible cash voucher prizes (1 × £30, 2 × £10).
