We used structural equation modeling to assess the role of impaired emotional awareness and clarity (Impaired Awareness/Clarity) and inability to control behaviors when experiencing emotional distress (Inability to Control Behaviors) as an account for the relationship between intolerance of uncertainty (IU) and negative affect (NA) in individuals with Substance Use Disorders (SUDs) and healthy controls (HCs) used for comparison. One-hundred and thirty-one individuals with SUDs (42.75% female; mean age = 39.74 ± 11.83) and 131 sex-matched HCs (mean age = 40.02 ± 12.34) entered the study. Participants completed questionnaires assessing the constructs of interest. Single-group analyses aimed to identify a baseline model for each group and test the hypothesized direct/indirect relations' overall significance. Then, a multigroup analysis tested the invariance of model parameters between SUD and HC groups. The model in which IU had both direct and indirect relationships with NA through Impaired Awareness/Clarity and Inability to Control Behaviors was a good fit to the data. The indirect relationship of IU with NA through Inability to Control Behaviors was significant and moderate-sized. The relationship involving Impaired Awareness/Clarity and Inability to Control Behaviors was small-sized and significant in single group analysis only. The multigroup analysis supported the association of IU with NA through Inability to Control Behaviors in the SUD group. Overall, our study highlights the crucial role of the Inability to Control Behaviors in SUDs and suggests that its association with IU might fuel NA in this population.
我们使用结构方程模型来评估情绪意识受损和清晰度受损（意识/清晰度受损）以及在经历情绪困扰时无法控制行为（无法控制行为）在物质使用障碍（SUDs）个体和用于比较的健康对照（HCs）中对不确定性不耐受（IU）与负面影响（NA）之间关系的解释作用。131名患有SUDs的个体（42.75%为女性；平均年龄 = 39.74 ± 11.83）和131名性别匹配的HCs（平均年龄 = 40.02 ± 12.34）进入了研究。参与者完成了评估相关构念的问卷。单组分析旨在为每组确定一个基线模型，并检验假设的直接/间接关系的总体显著性。然后，多组分析检验了SUD组和HC组之间模型参数的不变性。IU通过意识/清晰度受损和无法控制行为与NA具有直接和间接关系的模型与数据拟合良好。IU通过无法控制行为与NA的间接关系显著且中等大小。涉及意识/清晰度受损和无法控制行为的关系仅在单组分析中较小且显著。多组分析支持了SUD组中IU通过无法控制行为与NA的关联。总体而言，我们的研究强调了无法控制行为在SUDs中的关键作用，并表明其与IU的关联可能会加剧该人群的NA。
