The present study sought to address an issue in the drinking to cope (DTC) motives literature, namely the inconsistent application of treating DTC motives as a single construct and splitting it into DTC-depression and DTC-anxiety motives. Specifically, we aimed to determine if the effects of anxiety and depression on alcohol-related problems are best explained via their associations with DTC with specific affects or via their associations with a more global measure of DTC by testing four distinct models: the effects of anxiety/depression on alcohol-related problems mediated by DTC-anxiety only (Model 1), these effects mediated by DTC-depression only (Model 2), these effects mediated by a combined, global DTC factor (Model 3), and these effects mediated by both DTC-anxiety and DTC-depression (Model 4). Using path analysis/structural equation modeling across two independent samples, we found that there was a significant total indirect effect of both anxiety and depressive symptoms on alcohol-related problems in every model. However, there was a slightly larger indirect effect in all models using the global DTC motives factor compared to even the model that included the two distinct DTC motives. Our results provide some preliminary evidence that at least at the between-subjects level, a global DTC motives factor may have more predictive validity than separate DTC motives. Additional research is needed to examine how to best operationalize DTC motives at different levels of analysis (e.g., within-subjects vs. between subjects) and in different populations (e.g., college students vs. individuals with alcohol use disorder).
本研究旨在解决饮酒应对(DTC)动机文献中的一个问题,即把DTC动机视为单一结构与将其细分为DTC抑郁动机和DTC焦虑动机这两种做法的应用不一致。具体而言,我们旨在通过检验四个不同模型来确定焦虑和抑郁对酒精相关问题的影响,是通过它们与具有特定影响的DTC的关联来解释最好,还是通过它们与更全面的DTC测量指标的关联来解释最好:焦虑/抑郁对酒精相关问题的影响仅由DTC焦虑介导(模型1),这些影响仅由DTC抑郁介导(模型2),这些影响由综合的、全面的DTC因素介导(模型3),以及这些影响由DTC焦虑和DTC抑郁共同介导(模型4)。通过对两个独立样本进行路径分析/结构方程建模,我们发现每个模型中焦虑和抑郁症状对酒精相关问题都存在显著的总间接效应。然而,与包含两个不同DTC动机的模型相比,使用全面的DTC动机因素的所有模型中的间接效应略大。我们的结果提供了一些初步证据,表明至少在个体间水平上,一个全面的DTC动机因素可能比单独的DTC动机具有更高的预测效度。需要进一步研究,以探讨如何在不同分析水平(例如个体内与个体间)和不同人群(例如大学生与酒精使用障碍个体)中最好地操作化DTC动机。
