This exploratory latent-variable study sought to identify common sources of variance between two multifaceted sets of constructs: executive functions (EFs) and negative thoughts/affect. One-hundred ninety-two college students completed nine tasks representing three types of EFs (inhibition, updating, and shifting) and a set of questionnaires assessing four facets of negative thought/affect (anxiety symptoms, depression symptoms, worry, and rumination). Results indicated that, although the four negative thought/affect constructs were substantially correlated with one another, trait worry was the construct uniquely associated with EFs. Specifically, worry was associated with general EF abilities underlying all three subtypes of EFs (common EF), but was not associated with specific EF abilities (i.e., shifting-specific and updating-specific). These findings highlight the importance of partitioning common and specific variances in both EFs and negative thought/affect when examining the associations between these two research domains.

执行功能（EFs）和负面想法/影响。192 名大学生完成了九项任务，代表三种类型的 EF（抑制、更新和转换）和一组评估负面思想/影响的四个方面的问卷（焦虑症状、抑郁症状、担忧和反刍）。结果表明，尽管四个负面思想/影响结构彼此之间存在显著相关性，但特质担忧是与 EFs 唯一相关的结构。具体来说，担忧与所有三种 EF 亚型（共同 EF）背后的一般 EF 能力有关，但与特定的 EF 能力无关（即，转换特定和更新特定）。这些发现强调了在检查这两个研究领域之间的关联时，对 EFs 和负面思想/影响中的共同和特定方差进行划分的重要性。
