“…Indeed, treatments that incorporate some of these principles have recently provided very encouraging results in reducing drug treatment dropout and increasing the rates of abstinence among drug users. For instance, behavioral activation approaches that aim to activate individuals’ important goals and to increase their value by increasing individuals’ engagement in rewarding activities that support such goals (Jacobson et al, 1996; Lejuez, Hopko, Acierno, Daughters, & Pagoto, 2011; Lejuez, Hopko, & Hopko, 2001; Lewinsohn, 1974) have been successful in increasing substance-use treatment retention (Magidson et al, 2011), decreasing alcohol use among college students (Reynolds, MacPherson, Tull, Baruch, & Lejuez, 2011), and increasing smoking abstinence over 6 months (MacPherson et al, 2010). Furthermore, treatments designed to promote the use of healthier, nonsubstance-related strategies (in other words, alternative means) to fulfill chronic motivations related to substance use (e.g., sensation seeking) may lead to reductions in motivation to drink alcohol or use illicit drugs (Conrod, Castellanos-Ryan, & Mackie, 2011).…”
