Recent work on procrastination has begun to unravel the genetic and environmental correlates of this problematic behavior. However, little is known about how strongly procrastination is associated with internalizing and externalizing psychopathology, and the extent to which shared genetic/environmental factors or relevant personality constructs (e.g., fear of failure, impulsivity, and neuroticism) can inform the structure of these associations. The current study examined data from 764 young adult twins who completed questionnaires assessing procrastination and personality and structured interviews regarding psychopathology symptoms. Results indicated that procrastination was positively correlated with both internalizing and externalizing latent variables, and that these correlations were driven by shared genetic influences. Moreover, the association between procrastination and internalizing was accounted for by fear of failure and neuroticism, whereas the association between procrastination and externalizing was primarily explained by impulsivity. The role of procrastination in psychopathology is discussed using a framework that highlights common and broadband-specific variance.
近期关于拖延行为的研究已开始揭示这种问题行为的遗传和环境相关因素。然而，对于拖延行为与内化和外化心理病理学的关联强度，以及共享的遗传/环境因素或相关人格特质（如害怕失败、冲动性和神经质）在何种程度上能够解释这些关联的结构，我们所知甚少。本研究对764名年轻成年双胞胎的数据进行了分析，这些双胞胎完成了评估拖延行为和人格的问卷，以及关于心理病理学症状的结构化访谈。结果表明，拖延行为与内化和外化潜在变量均呈正相关，且这些相关性是由共享的遗传影响驱动的。此外，拖延行为与内化之间的关联可由害怕失败和神经质来解释，而拖延行为与外化之间的关联主要由冲动性来解释。本文使用一个突出共同和宽带特异性变异的框架，讨论了拖延行为在心理病理学中的作用。
