It depends on why she is screaming. Is she mad, or excited, or just thinks it is fun? To redirect the behavior, you have to analyze the function of the behavior. If it’s just for fun or due to excitement, I’d pick her up and put her on her room every time, immediately.
If she’s upset, she needs help with coping skills. I would not ignore a kid in crisis or one who is truly upset, so then you have to anticipate the screaming and teach her to substitute alternate behavior that is not so loud. She’s found this gets her feelings out and gets people to pay attention. See if you are sure you are responding to her bids for attention when she isn’t screaming.
