Hi jgarlovsky,
Good to hear from you! I work mainly with the adolescents, too! Yep, we often get the toughies, but I think that's more to do with the dual diagnoses, that is, teens with psych disorders combined with developmental disorders. So we have the psychotic teens who have the mental capacities of, on average, grade-schoolers.
I'm not exactly sure what you mean by "relapse" rate, but sometimes we do send them back to you guys for emergency treatment if there is a sharp(dangerous) change in behavior. I think the the tough cases are the ones that we can't handle and get sent to residential placements THAT ARE lockdown.
Being there for so long, I've seen the kids literally become adults (age 15 when I started, 18 now) and some of them make it out of the system okay, move away and get jobs. It's nice when they call and say Hi. It's really amazing what the right meds, some compassion and support, and a whole lotta patience can do. But you're right, the pay sucks, but I get by (barely).
I graduated from undergrad at a UC. You can PM me for more specifics.
