最近人们对精神病理学的维度和上位因素模型产生了兴趣。虽然早期研究根据代表“内化”和“外化”行为的两个维度来模拟精神病理学，但最近的研究已经开始确定一个独特的“精神病”维度。这项研究估计了包括所有三个维度的精神病理学的全局维度模型。还使用分类模型来解释跨维度的异质性。利用国家合并症调查的数据，11 个轴 I 诊断、行为障碍和三个精神病指标被用于探索性和验证性因素分析，确定了三个相关维度：内化、外化和精神病。潜在概况分析基于这些维度的因子得分，确定了五个在定性和定量上都不同的同质群体。讨论了以人为中心的精神病理学层次维度建模的好处。
There has been recent interest in dimensional and super-ordinate factor models of psychopathology. While early studies modelled psychopathology in terms of two dimensions representing "Internalising" and "Externalising" behaviours, more recent studies have begun to identify a distinct "Psychosis" dimension. This study estimated a global dimensional model of psychopathology that included all three dimensions. A categorical model was also used to explain heterogeneity across the dimensions. Using data from the National Comorbidity Survey, 11 Axis I diagnoses, conduct disorder and three indicators of psychosis were used in exploratory and confirmatory factor analyses which identified three correlated dimensions: Internalising, Externalising and Psychosis. Latent profile analysis, based on the factor scores from these dimensions, identified five homogeneous groups that differed both qualitatively and quantitatively. The benefits of person-centred modelling of the hierarchical dimensions of psychopathology are discussed.
