Listen to Eddie and make your delivery more natural. I’ve never seen an IRB requiring you to talk to research participants like a stiff. Relax. Be yourself. Treat them with respect and be natural. For instance, when you call somebody, ask for the person instead of identifying yourself immediately. If you called a your friend would you say “This is Judy Thomas from the University, is Cynthia there?” I wouldn’t.
Try it out. You’ll be surprised how far it gets you.
