Background

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.

Method

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_age = 50.61, SD_age = 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.

Results

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.

Conclusions

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.

寻求治疗的退伍军人中的抑郁症症状和酗酒：通过反刍思维的间接联系。

背景

退伍军人特别容易遇到与抑郁症和酗酒有关的并发问题。尽管存在这种公认的敏感性，但阐明可解释这种合并症的可靶向机制的研究仍然有限。本研究试图研究反刍思维过程在抑郁症和酗酒关系中的解释作用。

方法

该样本包括230名退伍军人，他们在一家大型退伍军人事务（VA）医院的一家普通精神病诊所就诊（男性83％，非洲裔美国人58％，M_年龄 = 50.61，SD_年龄 = 13.79）。作为摄入量评估的一部分，退伍军人完成了一系列简短的自我报告调查表，以帮助进行诊断说明和治疗计划。

结果

在抑郁症和滥用酒精之间可观察到明显的综合效果。还发现抑郁与反刍酒精滥用之间存在间接影响。值得注意的是，当检查两种反刍亚型时，通过反射性思考而不是沉思而不是在抑郁和酒精滥用之间产生了间接影响。

结论

研究结果表明，反刍思维处理可能是抑郁症和酗酒关系中的一个解释性危险因素。通过测试育雏沉思和反射思考的同时间接影响，本研究还提供了有关反射可能成为不良适应过程的情况的新颖见解。
