We are a group of researchers from Florida International University, investigating social group use and effects. Now, you’re invited to participate in a 20-minute study that examines the use of health-related social media. You will not be exposed to any risk beyond the risk experienced in everyday life. Your response to the survey questions will be completely confidential. Your participation is voluntary. As some of the questions are personal, if you feel any discomfort you can contact the researchers (María R.
