As a counter-anecdote, I know a mentally ill person (mostly functional, luckily, but he gets paranoid delusions during the worst times). His family pressed the doctors hard to have him involuntarily committed one time since he refused to go. From what I can tell, the primary effect of that is that he now has an intense distrust of doctors and those family members, and it would be a lot harder for doctors to help him now, even if they tried to approach him with more empathy.
The only people now who can sometimes talk him down when he's having problems are me and a couple of other family members that did not participate in pushing for involuntary committal.
