Abstract

Existing structural models of psychopathology need to be expanded to include additional diagnostic constructs beyond mood, anxiety, substance use, and antisocial behavior disorders. The goal of this study was to locate eating disorders within a hierarchical structural model of psychopathology that is anchored by broad Internalizing and Externalizing factors. Participants were female adolescent twins (N = 1,434) from the Minnesota Twin Family Study. The authors compared the fit of 4 models in which eating disorders (a) defined their own diagnostic class, (b) represented a subclass within Internalizing, (c) formed a subclass within Externalizing, and (d) were allowed to cross-load on both Internalizing and Externalizing. In the best fitting model, eating disorders formed a subfactor within Internalizing. These findings underscore the value of developing more comprehensive empirically based models of psychopathology to increase researchers' understanding of diverse mental disorders.

摘要

现有的精神病理学结构模型需要扩展,以纳入除情绪、焦虑、物质使用和反社会行为障碍之外的其他诊断结构。本研究的目的是在一个以广泛的内在和外在因素为基础的精神病理学层次结构模型中定位饮食障碍。参与者是来自明尼苏达州双胞胎家庭研究的女性青少年双胞胎(N=1434)。作者比较了 4 种模型的拟合度,其中饮食障碍(a)定义了自己的诊断类别,(b)代表内在因素中的一个亚类,(c)形成外在因素中的一个亚类,(d)允许同时在内在和外在因素上交叉加载。在拟合度最好的模型中,饮食障碍是内在因素的一个子因素。这些发现强调了开发更全面的基于经验的精神病理学模型的价值,以增加研究人员对不同精神障碍的理解。
