“…Research regarding the social networks of those seeking treatment for alcohol abuse indicates that treatment is more successful for individuals whose social networks are larger (Zywiak, Longabaugh & Wirtz, 2002), contain more non-family members (Gordon & Zrull, 1991), and actively support the individuals' recovery (Beattie & Longabaugh, 1997;Beattie & Longabaugh, 1999;Humphreys et al, 1999;Humphreys & Noke, 1997;Longabaugh & Wirtz, 2002). As individuals participate in treatment programs and alter their drinking behavior, the alcohol-specific attitudes and behaviors of their networks change as well, though many of the network members themselves stay the same (Beatttie & Longabaugh, 1999;Kelly et al, 2011;Humphreys et al, 1999;Mohr et al, 2001): changing the alcohol-specific attitudes of pre-existing network members appears to support individuals' recovery from alcohol abuse.…”
