“…Many groups use therapeutic models to assist with bringing about or maintaining change in substance use and relationships, and use approaches such as cognitive behaviour therapy (CBT; Horvarth & Yeterian, 2012), mindfulness approaches including dialectical behaviour therapy (DBT; Baer, 2006), or 12-step mutual help programs founded on principles of Alcoholics Anonymous (Emrick, 1987). Other groups provide opportunities for health education (Moos, 2008), for example, to increase a client's understanding of the addictive process, reduce the risks of ongoing substance use (Tross et al, 2008), build life skills (Arria et al, 2013), or enhance confidence and self-efficacy (Stevens, Jason, Ferrari, & Hunter, 2010).…”
