support for abstinence in the social networks of individuals with AUDs result in drinking outcomes similar to or better than those attained with more traditional treatments (Litt et al., 2007; Litt et al., 2009; UKATT Research Team, 2005). Similarly, drinking outcomes are improved when individuals attend AA as an adjunct to professional treatment (Bond et al., 2003; Kelly et al., 2011b; Stout et al., 2012), consistent with the association of stable AA attendance with abstinence in the current study.
