Linking Depression with Negative Alcohol-Related Consequences: A Structural Equation Model Among a Clinically Depressed Population.

Previous research suggests that rumination acts as a mediating mechanism in the association between depression and drinking motives, particularly drinking to cope, as well as negative alcohol-related consequences. In this study, we tested the connections between depressive symptoms, rumination, drinking motives, alcohol consumption, and alcohol-related problems in a clinically depressed population ( = 209). Structural equation modeling was used to test the models. Specifications were based on the results of a previously evaluated model in a sample of college students. The complex model showed a significant positive association between depressive symptoms and rumination. Drinking motives (enhancement and coping) were linked to more negative alcohol-related consequences. In a simplified model, pronounced depressive symptoms were associated with both increased ruminative thinking and more negative alcohol-related problems. Rumination was connected with stronger drinking motives (combined in one general factor), which were again associated with alcohol consumption and alcohol-related problems. The use of self-report measures to determine diagnostic validity. In a clinically depressed sample, depressive symptoms were linked to increased negative alcohol-related consequences. This association was partially explained by rumination and drinking motives. However, rumination was less relevant than previous studies suggested.
