I would look up individual programs in your area, perhaps ask your treatment team. A lot of IOPs in my area are focused on substance abuse, but PHPs are for everyone. I have been to IOPs that are for everyone, however. We learned all sorts of things that others have mentioned, like anger management, sobriety maintenance, coping skills, DBT, setting boundaries, and so on. I know of two PHPs one is for adolescents and is noon-6pm and one is 9am-2pm and two IOPs one is 3pm-6pm (also for adolescents) and one 6pm-9pm (for substance misuse).
