I see private practice therapists, and the study is talking about public mental health practices, and also possibly spending per those officially diagnosed with a mental illness, which I have not been. So I'm not sure you can conclude that public and private services are of the same quality in those states. There could be spillover in attitude towards mental health, but it's also possible public services in certain states aren't very good because private practices pick up the slack, and vice versa.

But I live in one of the top ten states, and didn't have any problems.
