movie from 70's

[dakini]

Hi
I'm looking for an American movie—I know, this is a forum about european movies but I don'y know where to ask...

So, it's a girl that was admitted to psychiatric hospital by her parents
There she is raped, etc.

Eventually she became kind of obsessed with sex and kind of a Satanist, as I remember.

Eventually she comes home and takes revenge on her parents...

Any ideas of the name of the movie?
I remember that it was a 70's movie, and one of the hospital employees was a Black male...
Thanks.

Have a look at...

Defiance of Good 1974 (Edit - Hmmmm - doesn't really have the 'return home and take revenge' aspect)

Sharon 1976 (Edit - Nope - Just watched it and it's not got the 'prison' aspect...)

both featuring Jean Jennings - the 'troubled girl' who get institutionalised - Defiance of Good also seems to have a 'Satanism' overtone
