We examined whether executive functions (EFs) mediate the relation between procrastination and attention-deficit/hyperactivity disorder (ADHD) symptoms in college students. One hundred fourteen undergraduates were recruited for study participation. Participants completed measures of academic performance, procrastination, ADHD symptoms, EFs (as measured by five EF facets: time management, organization/problem-solving, restraint, motivation, and emotion regulation), and common comorbid concerns for college students between May 2017 and May 2018. A mediational framework was utilized to examine the associations among procrastination, EFs, and four ADHD symptoms domains. Results indicated that both procrastination and GPA correlated with EFs and three ADHD symptom domains. While EFs mediated the association between procrastination and ADHD symptoms, follow-up analyses suggested that self-management of time and organization/problem-solving are the specific pathways through which procrastination is indirectly associated with ADHD symptoms. Promising areas for future research and potential intervention targets are discussed.
我们考察了执行功能（EFs）是否在大学生中在拖延和注意力缺陷/多动障碍（ADHD）症状之间起中介作用。招募了 114 名本科生参与研究。参与者完成了学业表现、拖延、ADHD 症状、执行功能（通过五个 EF 方面进行衡量：时间管理、组织/解决问题、克制、动机和情绪调节）以及大学生常见共病问题的测量，时间在 2017 年 5 月至 2018 年 5 月之间。采用中介框架来检验拖延、EFs 和四个 ADHD 症状领域之间的关联。结果表明，拖延和 GPA 均与 EF 和三个 ADHD 症状领域相关。虽然 EFs 中介了拖延和 ADHD 症状之间的关联，但后续分析表明，时间管理和组织/解决问题的自我管理是拖延与 ADHD 症状间接相关的具体途径。讨论了未来研究和潜在干预目标的有前景的领域。
