Yale REDCap survey consent and screening for a study on how psychedelics affect the brain

The Yale REDCap survey gathers consent and eligibility screening for a research study on how psychedelics affect the brain. Participants expect about 45 minutes at a computer, an eligibility questionnaire covering psychedelic and other drug use plus mental health and unusual sensory experiences, and SMS verification of a mobile number. Researchers indicate there is a 24 to 48 hour wait while eligibility is checked, with $10 compensation via Amazon gift card. The study requires a stable internet connection and a non-VPN IP address in an OECD country, and it includes an optional visual detection game. The consent flow also emphasizes honesty and effort, disallows copy and paste AI-generated responses (with an option to identify as an AI agent), and states that payment may be withheld if responses appear fraudulent, illogical, or inattentive.
