McKeon is known for carefully researching her roles and characters. For her role in "The Division", she spent time with a police force, while for her role in "Strange Voices", she spoke with patients about the condition to prepare for her role. In an interview with John Tesh, she said, "What's really interesting is that I find that people are very forthcoming to actors. I mean, almost more forthcoming than they are to priests or shrinks, because they somehow feel that their story is going to be out there in someway...But, once you get into talking with them and finding out about their world, it's fascinating and it's heartbreaking at the same time."
