The high rate of comorbidity between alcohol use and emotional disorders is well demonstrated, but the mechanisms underlying their relationship remain largely unidentified. One possibility is maladaptive responding to negative affect, such as worry and rumination. The present study sought to examine worry and rumination as putative mediators explaining the link between emotional disorders and alcohol use disorders. Methods Mediational analyses were conducted using a sample (n = 232) derived from a larger late adolescence/early adulthood longitudinal dataset (Youth Emotion Project; Zinbarg et al., 2010). Results A significant indirect effect was observed for emotional disorder severity on alcohol use disorder severity via rumination, but not via worry or the shared variance between worry and rumination. Conclusions These findings suggest that rumination may specifically confer risk for the development of alcohol use disorder for individuals with emotional disorders. Further, ruminative thinking may serve as a specific treatment target to reduce vulnerability to alcohol use disorder.
酒精使用与情绪障碍之间的高共病率已得到充分证实，但其关系背后的机制在很大程度上仍不明晰。一种可能性是对诸如担忧和沉思等负面影响的适应不良反应。本研究旨在检验担忧和沉思作为假定中介因素，以解释情绪障碍与酒精使用障碍之间的联系。方法 使用从一个更大的青少年晚期/成年早期纵向数据集（青年情绪项目；津巴格等人，2010年）中抽取的样本（n = 232）进行中介分析。结果 观察到情绪障碍严重程度通过沉思对酒精使用障碍严重程度有显著的间接影响，但通过担忧或担忧与沉思之间的共同方差则没有。结论 这些发现表明，沉思可能特别会使患有情绪障碍的个体面临酒精使用障碍发展的风险。此外，沉思性思维可能作为一个特定的治疗靶点，以降低对酒精使用障碍的易感性。
