“…The BDI reflects the magnitude of depressive symptomatology over 1 week, which can be strongly influenced by recent life events and environmental circumstances (Richter et al, 1998), including substance abuse treatment. In multiple studies, a diagnosis of a unipolar mood disorder was associated with relapse in AUD treatment [see (Durazzo et al, 2008, Hobbs et al, 2011, Suter et al, 2011, Greenfield et al, 1998, Rounsaville et al, 1987)], while level of self-reported depressive symptomatology was not related to relapse in others (Soyka and Schmidt, 2009, Durazzo et al, 2008, Bradizza et al, 2006, Greenfield et al, 1998). Comorbid recurrent MDD may be associated with greater probability of relapse for a number of reasons: Individuals with AUD and comorbid MDD demonstrate greater maladaptive coping skills, dysfunctional emotional regulation, and abnormal functioning of the hypothalamic-pituitary-adrenal cortex axis (Kahler et al, 2002, Compare et al, 2014, Moses and Barlow, 2006), which are associated with increased risk of relapse (Moos and Moos, 2007, Seo and Sinha, 2014, Berking et al, 2011); those with AUD and comorbid MDD may resume alcohol consumption to ameliorate the core symptoms of recurrent MDD (Hesselbrock et al, 1986, Pettinati et al, 2013).…”
