The study generated survey data. Participants were aged over 18 years and were recruited from the UK general population. The study was conducted online, and participants were recruited via social media sites. On those sites, brief study details were provided, along with a weblink to access the information sheet and survey questions. Prior to taking part, individuals were informed that participation would involve being presented with questions about experiences of adversity and mental health. Responses were entirely anonymous, with no personal identifier information collected. Participants were required to acknowledge their consent via a tick box.
