I'm not sure I understand what you mean by a hospital psychology unit, but that may just be because you are from the UK. In the US hospital units are generally called psychiatric units because they are very medically based (read medications).

It sounds like maybe you are being referred to an outpatient hospital program? Would that be right? If so, it is hard to tell you what to expect because there are so many different configurations that exist.

I've never done outpatient hospital programs, but have been inpatient many times and know how the outpatient programs work (at my hospital). There are several types of outpatient hospital programs at my hospital. Generally the people in the program were inpatient recently and the outpatient program is a step down program. But I do think it is possible to go straight into the outpatient program without having been inpatient recently. Generally, the outpatients arrive on the hospital unit in the morning and stay until mid-afternoon. They participate in the groups that go on throughout the day. They see their psychiatrist each day.

The other program offered is a psychiatric outpatient program that is completely separate from the inpatient unit. I don't know as much about that program.

Generally I think these programs are very group-based. I've never seen any individual therapy going on, but again, I'm not even sure I'm addressing the kind of program you are talking about.

Whatever the case, I hope it all works out for you. Keep us informed.
