I think overall the availability of some types of mental health care is much lower than in the past.
With Reagan and the 1980s came a movement towards “community mental health.” Psychiatric facilities were massively defunded and many shut down, with the Federal government pushing treatment to community mental health providers, States mostly shut down the majority of their State psychiatric facilities.
The feel good reason for this is that there was an assertion that lots of people were being (expensively) institutionalized who could survive out in the community with the proper help. Community mental health providers who generally control chartered areas of States, could provide community based resources. These took the forms of some low security psychiatric facilities, but mostly it was group homes, and support staff who would check up on people in independent living.
This certainly has not been all bad, and in fact for some populations it’s been really good. One population that has done really well with this transition are people with developmental disorders, who frankly were largely just institutionalized because they need some level of care for much of their days but really don’t need to be in a locked down institution. However, when they reach adulthood it is often too great a burden for parents to take care of them–and most of them also outlive their parents. Group homes are a much better living situation for them, giving them more exposure to the community and something more akin to a normal life, but with the help and support they need.
One population that I think has probably not benefitted well from this transition are people with forms of schizophrenia that involves psychotic episodes, schizophrenia is increasingly understood more as a term for a lot of somewhat related mental health afflictions, so you never want to generalize about “all people with schizophrenia”, but a lot of people with the more tragic forms of schizophrenia do very poorly in the community. However, they often don’t meet the new criteria for institutional care, and they are usually too strong willed to be kept in group homes and voluntary treatment–many end up in serious drug addiction and homelessness. These are people who have truly a tragic condition, you hate to say that anyone would be better off in a locked psychiatric facility, but some of these people actually fall in that exact category, and by and large they cannot get the care they need.
When I worked for Virginia’s BHD, our State psychiatric facilities had two classifications of commitments–civil and forensic. Forensic meant that they were essentially committed as part of a criminal court process. Forensic commitments were always given a high priority for placement because there is basically a court order saying these people have to be committed or put in prison. Civil commitments likely are a much bigger population of people who need them, but because criminal court commitments take up sort of first preference, there are limited civil beds available and a ton of people that basically don’t get the care they need.
