Aloha HD,

I'm doing both right now- (yup, I will do anything to feel better... )

The major differences I see are time and the severity of illness. I spend 3 day a week, 3 hrs a day in IOP and 1.5 hours a week in group therapy sponsored by the psychology group I use for private therapy sessions.

For me, I am more comfortable at the IOP program because my MI is so severe. Most have had recent Sui attempts or are unstable BPD etc... The DBT is intense and the others can be very helpful when dealing with crisis situations. The weekly group therapy is mainly moderate anxiety, moderate depression, mod PTSD, ADHD... Although there is one person who has severe resistant depression like me.

Good luck and I hope you find the right fit for you!
