My general residency had an Anxiety, Personality DO, Substance Abuse, Bipolar, Perinatal, and Treatment resistant depression/ECT clinics. We also had a "general" clinic that would take anything in-between. Psychosis experience was basically spending a day at community mental health, our psych ER, plus the 1st 2 years seeing a lot of psychosis in an inpatient.
For my child fellowship we have an ADHD, Anxiety, treatment resistant depression/ECT, and Autism. We also have general clinics that can takes kids that don't fit into those.
Personally, I really like having speciality clinics. It helps even out the types of patients you see and you get to work with attendings who are experts in those areas.
