The time commitment depends on the type of study. Surveys may take 10-20 minutes, where focus groups may take 1-2 hours. Treatment studies could take months or years, but you may only be asked to come in for a visit once every few months. It all depends on what the study is looking at. The time commitment will be outlined in the informed consent, but you should ask the study team if this is a concern before agreeing to take part in the study.
