It has been a while ago, but I was expected to work a step per week while in intensive outpatient for the 6 weeks of the IOP section of their program. I was also expected to make a meeting the 2 nights a week I was not in Intensive Out Patient. And to have a sponsor before I graduated to "aftercare" (2 x 2 hour sessions a week in the treatment center instead of 5 x 4 hour sessions) for the rest of the year of treatment.
Looking back..my stepwork while in treatment was sorely lacking in depth, more focused on what I thought they wanted to hear than "reality". To top it off, I used "doing my 4th step in treatment" as a handy excuse to not work a real 4th step with my sponsor for a year.
