Introduction: Depression is one of the most prevalent mental illnesses in the United States, and is characterized by feeling sad or empty most of the day, nearly every day (American Psychiatric Association, 2013). The experience of childhood trauma is one of many factors that may lead to depression, while trauma can also yield other adverse life outcomes, such as alcohol-related consequences (Felitti et al., 2001; Neumann, 2017). One of the specific aims of this investigation was to examine the direct influences of childhood trauma on depression. We also examined selected direct and indirect influences of childhood trauma on drinking outcomes through the potential mediating mechanism of depression. We examined three distinct drinking outcomes, 1) impaired control over drinking (i.e. the inability to stop drinking when intended), 2) heavy episodic drinking (four or more drinks on one occasion for men, four or more for women), and 3) alcohol-related problems. Methods: A survey was administered to 940 (466 women, 474 men) university students. Structural equation modeling was used to examine the data. Potential two- and three-path mediated effects were examined with the bias corrected bootstrap technique in Mplus (MacKinnon, 2008). Results: Emotional abuse was found to be positively associated with depression. In contrast, having an emotionally supportive family was found to be negatively associated with depression. Congruent with the Self-Medication Hypothesis, depression was found to be positively associated with impaired control over drinking. Physical neglect was found to be positively associated with impaired control. Lastly, emotional abuse was found to be indirectly linked to increased heavy episodic drinking and alcohol-related problems through depression and impaired control.
