Introduction Alcohol use disorders (AUD) and major depressive disorder (MDD) co-occur frequently in both the general population (Carton et al. 2018) and specifically among those seeking treatment for substance use (SU) (Grant et al. 2004). Individuals in SU treatment with cooccurring mood disorders experience worse outcomes (Torrens et al. 2005) and higher rates of relapse following treatment termination (Hasin et al. 2002). Identifying shared vulnerabilities associated with these disorders has the potential to improve identification of at-risk individuals entering SU treatment and could yield more effective and targeted intervention strategies. Thus, the current study examined the role of two psychological factors commonly implicated in the onset and maintenance of AUDs, delay discounting and distress tolerance, that may influence co-occurring MDD among a sample of individuals receiving inpatient SU treatment. * Julia W.

Delay discounting, or the tendency to perceive something as less valuable when its receipt is delayed, has been consistently linked to disordered alcohol use among adults (Bailey et al. 2018; Bickel et al. 2014). Although less attention has been paid to the relation between delay discounting and depression, emerging research suggests that individuals with MDD also have higher rates of discounting (Pulcu et al. 2014). Indeed, depression has been shown to be associated with abnormal reward processing (Beddington et al. 2008), such that individuals high in anhedonia and hopelessness (two critical symptoms of MDD) are less likely to value rewards that take place in an uncertain future. A large body of literature also shows links between distress intolerance (the inability to tolerate psychological distress), and both problematic alcohol use, and depression (Khan et al. 2018; Allan et al. 2014
