Mediational Role of Drinking to Cope in the Associations of Depression and Suicidal Ideation with Solitary Drinking in Adults Seeking Alcohol Treatment

摘要

Background: Little research on solitary drinking has focused on clinical samples. Previous research in college students has found that depression, suicidal ideation, and drinking to cope with negative affect are associated with drinking in solitary, but not social, contexts. These associations have not been examined among individuals with alcohol use disorder, despite their high rates of depression and suicidal behavior. Method: To fill this gap in knowledge, the associations of depression and suicidal ideation with solitary and social drinking were examined among 96 individuals seeking alcohol treatment, the majority of whom had alcohol use disorder (97.9%). Multiple mediation models were conducted to examine the mediating effects of two drinking to cope variables (drinking excessively to cope and coping motives) on the associations of depression and suicidal ideation with drinks per month and heavy episodic drinking in social and solitary contexts. Results: Significant indirect effects were found for depression and suicidal ideation with solitary drinking variables through greater drinking excessively to cope. No significant indirect effects were found for social drinking variables. However, a positive direct association was found between suicidal ideation and greater social drinks per month that was not mediated by drinking to cope. Conclusions: These findings suggest that greater depression or suicidal ideation, through their effect on greater drinking to cope, are associated with greater solitary drinking in a treatment seeking sample. Drinking context should perhaps be considered in alcohol interventions, particularly when treating individuals suffering from depression or suicidal ideation.
