Veterans are particularly vulnerable to experiencing concurrent issues related to depression and alcohol misuse. Despite this well-established susceptibility, research explicating targetable mechanisms that can account for this comorbidity remains limited. The present study sought to examine the explanatory role of ruminative thought processing within the depression and alcohol misuse relationship.
The sample included 230 veterans presenting to a general mental health clinic at a large Veterans Affairs (VA) hospital (83% male, 58% African American, M = 50.61, SD = 13.79). As part of their intake evaluation, veterans completed a brief battery of self-report questionnaires to assist with diagnostic clarification and treatment planning.
A significant total effect was observed between depression and alcohol misuse. An indirect effect between depression and alcohol misuse via rumination was also found. Notably, when examining two subtypes of rumination, an indirect effect between depression and alcohol misuse via reflective pondering but not brooding was evinced.
Findings suggest that ruminative thought processing may be an explanatory risk factor within the depression and alcohol misuse relationship. By testing the simultaneous indirect effects of brooding rumination and reflective pondering, the present study also offers novel insights concerning the circumstances under which reflection may become a maladaptive process.
退伍军人特别容易同时出现与抑郁和酒精滥用相关的问题。尽管这种易感性已经得到充分证实，但仍缺乏能解释这种共病的可靶向机制的研究。本研究旨在探讨沉思性思维处理在抑郁和酒精滥用关系中的解释作用。
该样本包括 230 名前往大型退伍军人事务部 (VA) 医院综合心理健康诊所就诊的退伍军人（83%为男性，58%为非裔美国人，M=50.61，SD=13.79）。作为他们的入院评估的一部分，退伍军人完成了一套简短的自我报告问卷，以协助明确诊断和制定治疗计划。
抑郁和酒精滥用之间观察到显著的总效应。还发现了沉思通过反刍在抑郁和酒精滥用之间的间接效应。值得注意的是，当检查两种沉思亚型时，发现抑郁和酒精滥用通过反思性思考而不是沉思之间存在间接效应。
研究结果表明，沉思性思维处理可能是抑郁和酒精滥用关系中的一个解释性风险因素。通过测试沉思性反刍和反思性思考的同时间接效应，本研究还提供了关于在什么情况下思考可能成为一种适应不良过程的新见解。
