There are a handful of scholarly summaries of the alcohol treatment literature. Of the many treatment procedures for which clinical trials have been conducted, one half dozen are clearly shown to be effective. This effectiveness is supported by consistent findings across several studies. They do not have a spiritual or disease model or 12-step foundation. All these treatments are essentially cognitive-behavioral in nature, and involve the correction of distorted thinking, the identification of goals, and the development of new habits.
Several qualifications are in order.
These clinical trials have primarily tested treatments, not support groups. I hope you will find it comforting to consider that as we evolve we will not only be different, but even better.
