Question: Can anyone please provide recommendations for how / where I can recruit healthy participants (roughly between the ages of 18 - 25) for an online survey-based study?
Context: I am designing a study comparing certain variables in a specific patient population vs healthy age-and-sex-matched controls. I have access to the clinical population, but am unsure where I can recruit healthy controls (my university's psychology student participant pool is not available to me). Data collection will be via a very brief online survey. Ideally any recommended platform would enable me to choose participants based on age-sex combination. My team is open to paying participants.
