Trying to find out title of scary movie I saw in the 80s

I'm trying to find information on a movie that I remember watching as a kid. If I remember correctly, the movie aired on one of the big 3 (ABC, CBS or NBC) on a Saturday night back when the TV stations used to do the Saturday night movie thing. I've always assumed this movie was made-for-tv, but it could have been a movie that had been at theatres at one point.
From what I can remember, the movie was about a little girl who killed her family members one by one. The movie's climax has the little girl confronting her mother (trying to kill her?).
I must have seen this movie between five and ten years old. I guess the house I remember seeing it in would have put me around 10ish, which would've meant I saw this movie in the mid-80s. I don't know if that was the first time it aired or not.
My parents kept me from seeing scary movies as a kid, so seeing this movie was pretty scary to me at the time. I've always thought it was that movie that made me dislike the horror / scary movie genre. Now that I'm an adult, I'd like to watch this flick to see if it was really scary or not.
Any clues or ideas about how I can pinpoint this movie would be very appreciated. Thanks in advance.
