Abstract Distress tolerance has been implicated in the emergence of internalizing symptomatology, notably depressive symptoms. However, few studies have tested potential mechanisms underlying the relationship between distress tolerance and depressive symptoms, and further, this has not been tested among substance users, who commonly experience both low distress tolerance and elevated depressive symptoms. The current study focused on the construct of rumination, which has been suggested to be a coping response to stress associated with substance use and depression. Two forms of rumination, brooding and reflection, were tested as potential mediators of the relationship between distress tolerance and self-reported depressive symptoms among 128 individuals entering substance abuse treatment. Brooding (i.e., to overly focus on symptoms of distress) mediated the relationship between distress tolerance and depressive symptoms. However, reflection (i.e., to attempt to gain insight into problems) was unrelated to distress tolerance. Findings suggest the important role of brooding as a mechanism underlying the relationship between distress tolerance and depressive symptomatology. J. F. Magidson A. R. Listhaus C. J. Seitz-Brown K.

Introduction Depressive symptoms are commonly elevated in substance using populations. Over 50 % of individuals present to substance abuse treatment with clinically significant depressive symptoms (Johnson et al. 2006), which are associated with increased likelihood of substance abuse treatment dropout (McKay et al. 2002; Tate et al. 2004; Thase et al. 2001) and relapse (Hasin et al. 2002). Despite the clinical significance of comorbid depression, few studies have tested conceptual models to better understand factors that contribute to depressive symptoms among substance users. Emerging evidence suggests a relationship between distress tolerance (DT), defined broadly as one’s capacity to withstand aversive physical and psychological states (Brown et al. 2005; Simons and Gaher 2005), and both elevated depressive symptoms (Abrantes et al. 2008; Daughters et al. 2009; Harrington 2006; Schmidt et al. 2006) and major depressive disorder (Ellis et
