Rage-reduction, holding, or attachment therapy

Are these practices that should be avoided?

In the 1969 movie, Change of Habit, Elvis Presley stars as an inner-city doctor and Mary Tyler Moore plays a nun who, in cognito, is collaborating with the doctor to improve life in a ghetto (see IMDb). In a subplot, Dr. Carpenter (Elvis) provided something like rage-reduction therapy for a little girl with autism; the child is cured in, like, one session. Readers can watch a produced version of the trailer on YouTube:

Of course, rage-reduction therapy didn’t work quite the way it was depicted in the movie. For those who know about rage-reduction therapy, this is no surprise.

The theory is that by having the patient rage, the patient’s “inner anger” will be dissipated—Hence, rage-reduction therapy. Rage-reduction therapy is sometimes recommended for children (and youths) who have “reactive attachment disorder,” who have experienced horrible early lives, who have autism, who are “maladjusted,” and so forth.
