I went to ACA meetings for about 6 months back in 1986. I have also attended various other twelve step groups. However, I haven't been to a 12 step meeting in over 13 years.
I was not a JW at the time, so I was unaware of what the Org's view of them were.
My opinion of ACA and other 12 step groups.
The good
1. I found a group of people that understood my pain without deep explanations.
2. I was able to come to grips with the tremendous shame I felt.
3. I came to understand my family dynamics and my role in them.
4. Received emotional support and encouragement.
The Bad
1. Even though the literature does not directly state it is the ONLY way to be "sober", "clean", and "abstinent", the is an underlying message that it is.
2. One MUST rely on a "higher power" in order to achieve wellness. I don't care what they say...IT'S GOD.
3. Because of anonymity, there are no studies, or facts, to SUPPORT that 12 programs are successful. And what has been written, only shows how miserably AA, NA, etc., fail overall.
4. Encourage people (ACA) to act like small children. Hence, "listening to your inner child".
5. Contradicting messages. For example, telling people they are "powerless". Yet, saying they "made the decision". One that is powerless cannot make decisions.
6. The disease concept. In the case of twelve step programs, people diagnose THEMSELVES. No medically supervised diagnosic testing is done. "If you think you are, then you are".
7. Anyone who even HINTS at drinking, druggin, eating, etc. too much, is an alcoholic, addict, or compulsive eater. And if that person does not agree they are in "denial".
8. Group Think is rampant in 12 step programs. Particularly in treatment programs. I have seen it first hand. If you express an opinion contrary to what is "official" others in the group pressure you to change your opinion. "you are in denial" "you will NEVER recover".
An excellent book to read on this subject is:
