Recent years have seen a shift toward alternative nosologies of psychopathology, which frequently include a dimension of externalizing psychopathology. The Hierarchical Taxonomy of Psychopathology is one such framework. Research using data from the Adolescent Brain and Cognitive Development (ABCD) Study has identified a broad-based externalizing dimension, but no research to date has sought to empirically identify finer-grained externalizing subdimensions despite the research benefits associated with the use of homogenous dimensions. Furthermore, no work to date has examined whether externalizing dimensions are invariant over time. Thus, the current study had two primary aims: Aim 1-identify the hierarchical structure of externalizing psychopathology and examine evidence of discriminant validity of identified dimensions and Aim 2-assess the longitudinal measurement invariance of a broad externalizing dimension in the ABCD Study, as well as specific underlying subdimensions. The results for Aim 1 analyses identified a coherent factor structure comprising a broad externalizing dimension and three subdimensions (conduct problems, irritability, and neurodevelopmental problems), and these factors showed important similarities and differences in relation to external correlates. Aim 2 analyses showed that strong invariance was supported for the conduct problems and irritability dimensions, while partial strong invariance was supported for broad externalizing and neurodevelopmental problems. Quantification of measurement (non)invariance revealed small effect sizes. The results highlight important directions for future research on externalizing psychopathology in the ABCD Study.

近年来，精神病理学的分类方法已转向其他体系，这些体系通常包含外化性精神病理学维度。精神病理学层次分类法就是这样一个框架。利用青少年大脑与认知发展（ABCD）研究数据开展的研究已经确定了一个基础广泛的外化性维度，但尽管使用同质维度具有研究优势，但迄今为止尚无研究试图通过实证确定更细化的外化性子维度。此外，迄今为止也没有研究考察外化性维度是否随时间保持不变。因此，本研究有两个主要目标：目标1——确定外化性精神病理学的层次结构，并检验所确定维度的区分效度证据；目标2——评估ABCD研究中一个广泛的外化性维度以及特定潜在子维度的纵向测量不变性。目标1分析的结果确定了一个连贯的因子结构，包括一个广泛的外化性维度和三个子维度（行为问题、易怒和神经发育问题），并且这些因子在外部相关因素方面表现出重要的异同。目标2分析表明，行为问题和易怒维度支持强不变性，而广泛外化性和神经发育问题支持部分强不变性。测量（非）不变性的量化显示效应量较小。研究结果突出了ABCD研究中外化性精神病理学未来研究的重要方向。（PsycInfo数据库记录（c）2025美国心理学会，保留所有权利）
