“…However, more proximal outcomes (e.g., depression, anxiety) in relation to BPD have been largely unexplored, despite the fact that they occur at rates ranging from 25% to 61% in residential treatment facilities and are 4.7 times more prevalent in addictions samples than in community samples (Hasin & Nunes, 1997; Huang et al, 2006; Kessler et al, 2003; Nunes, Sullivan, & Levin, 1997; Regier et al, 1990; Rounsaville et al, 1991). These findings have important implications for treatment settings, as many residential addictions facilities have begun to treat both SUDs and the comorbid psychopathology that may contribute to relapse (e.g., anxiety, depression; Harrison et al, 2008; Kosten, Rounsaville, Kleber, 1986; Moore, Young, Barrett, & Osborn, 2009; Willinger et al, 2002; Yong, Barrett, Engelhardt, & Moore, under review). It is possible that BPD features serve as an additional barrier to treatment due to their impact on the maintenance of these forms of comorbid psychopathology.…”
