一些理论已经提出了一个共同的内在因素，以帮助解释情绪和焦虑症之间的关系。这些疾病往往是共病和强烈的共变。其他理论和数据表明，人格特质可能至少部分地解释了抑郁和焦虑之间的共病。本研究探讨了神经质和情绪和焦虑障碍共同的内化维度之间的关系。一个样本的种族多样化的青少年（N=621）完成自我报告和同行报告的神经质的措施。参与者还完成了DSM-IV的结构化临床访谈。结构方程模型表明，一个单一的内化因素是共同的终身诊断的情绪和焦虑障碍，这个内化因素与神经质强烈相关。神经质与内化因子（r= 0.98）的相关性比与物质使用因子（r= 0.29）的相关性更强。因此，神经质具有聚合效度和区分效度。这些结果进一步证明神经质是情绪和焦虑症结构理论中的一个必要因素。在本研究中，内化精神病理学与神经质之间的相关接近1.0，表明神经质可能是内化精神病理学的核心。未来的研究需要在其他人群中检查这种可能性，并复制我们的发现。
Several theories have posited a common internalizing factor to help account for the relationship between mood and anxiety disorders. These disorders are often comorbid and strongly covary. Other theories and data suggest that personality traits may account, at least in part, for comorbidity between depression and anxiety. The present study examines the relationship between neuroticism and an internalizing dimension common to mood and anxiety disorders. A sample of ethnically-diverse adolescents (N=621) completed self-report and peer-report measures of neuroticism. Participants also completed the Structured Clinical Interview for DSM-IV. Structural equation modeling showed that a single internalizing factor was common to lifetime diagnosis of mood and anxiety disorders, and this internalizing factor was strongly correlated with neuroticism. Neuroticism had a stronger correlation with an internalizing factor (r=.98) than with a substance use factor (r=.29). Therefore, neuroticism showed both convergent and discriminant validity. These results provide further evidence that neuroticism is a necessary factor in structural theories of mood and anxiety disorders. In this study, the correlation between internalizing psychopathology and neuroticism approached 1.0, suggesting that neuroticism may be the core of internalizing psychopathology. Future studies are needed to examine this possibility in other populations, and to replicate our findings.
