The six week outpatient program I attended consisted of 3 hour and half information/lecture sessions a week, one hour and a half group therapy meeting a week, and one hour long individual therapy meeting a week. In addition, we were encouraged to attend at least 3 AA or NA meetings a week.
For me, the outpatient experience was valuable and I do not regret any of it. After I finished the six week program, I continued on with the treatment center's Early Recover Program (one hour and half group therapy session with additional individual therapy sessions available) for the rest of the first year. I don't regret that experience either.
However, all the time I was involved in treatment, I was also attending AA and NA meetings and I believe the 12 step programs were far more important for my long term sobriety and I continue to work them today.
By the way, for what it is worth, today is exactly my 7 year anniversary in recovery. I don't regret that either.
