This study compared a series of higher-order models encompassing symptoms of both clinical and personality disorders. The final model was then correlated with a latent variable model of normal personality traits. A total of 420 undergraduates completed a battery of self-report symptom and personality questionnaires, with informant-reports and diagnostic interviews provided by overlapping subsamples. A three-level model with two factors at the highest level and four factors at the second level was the best fitting model. The higher-order internalizing and externalizing factors were then correlated with 30 latent personality facets. Results demonstrate an elevation on the neuroticism facets for the higher-order internalizing factor, along with low positive emotions, low actions, and low competence. The higher-order externalizing factor was negatively associated with most conscientiousness and agreeableness factors, while showing an elevation on excitement-seeking, impulsivity, and angry hostility. Future studies should replicate these models with the inclusion of more low base-rate disorders (i.e., psychosis).
本研究比较了一系列包含临床症状和人格障碍症状的高阶模型。然后将最终模型与正常人格特质的潜在变量模型进行关联。共有420名本科生完成了一系列自我报告症状和人格问卷，部分重叠子样本提供了知情者报告和诊断访谈。一个在最高层次有两个因素、在第二层次有四个因素的三级模型是拟合度最佳的模型。然后将高阶内化和外化因素与30个人格潜在方面进行关联。结果表明，高阶内化因素在神经质方面有所升高，同时积极情绪较低、行动力较低且能力较低。高阶外化因素与大多数尽责性和宜人性因素呈负相关，同时在寻求刺激、冲动性和愤怒敌意方面有所升高。未来的研究应纳入更多低发病率障碍（如精神病）来复制这些模型。
