Although the qualifications for membership in 12 step support groups is specifically defined, generally it is the individual members themselves that decide if the "belong" to the group or not.
Alcoholic AnonymousBoth Alcoholics Anonymous and Al-Anon open their doors and offer fellowship to anyone who fits the eligibility outlined in Tradition 3 and generally leave that determination up to the individual. Basically those who attend these 12 step meetings either feel a sense of "belonging" or they do not and move on.
Tradition 3: The only requirement for A.A. membership is a desire to stop drinking.
Tradition 3: The relatives of alcoholics, when gathered together for mutual aid, may call themselves an Al-Anon Family Group, provided that, as a group, they have no other affiliation. The only requirement for membership is that there be a problem of alcoholism in a relative or friend.
The reason that Tradition 3 was emphasized by the founders of the 12 step programs was to protect the fellowship from outside influences; to insure that the meetings would maintain their primary focus and not be diluted by the influx of others issues or influences.
Some old timers today believe that the fellowship has in fact been diluted by the inclusion into its meetings those who are primarily dealing with issues other than problems with alcohol, such as drug abuse. They feel that the program has gotten away from its spiritual foundations and primary purpose and may become diluted to the point of ineffectiveness.
