The Youth Self-Report Form's (YSR's) factor model was derived from traditional exploratory factor analytical procedures. Assuming appropriate model specification, psychometrically invariant items, and that its items provide useful psychometric information across nations omitted from its normative samples, the YSR is widely used in cross-national studies of nonreferred children. Item response theory analytical procedures reveal (a) 2 dimensions partly overlapping with the YSR's Internalizing and Externalizing second-order factors; (b) variance (i.e., differential item functioning) in how well a few items discriminate for nonreferred children across two nations; and (c) variance in estimating severity levels in children with identical psychopathological severity cross-nationally. Addressing psychometric variance, limiting redundancy, and matching children's psychopathological severity levels with items measuring this severity might promote more accurate and economical assessment.
青少年自我报告表（YSR）的因素模型源自传统的探索性因素分析程序。假设模型规范恰当、项目具有心理测量不变性，且其项目能在其常模样本中未涵盖的各个国家提供有用的心理测量信息，YSR被广泛用于非转介儿童的跨国研究。项目反应理论分析程序揭示：（a）两个维度与YSR的内化和外化二阶因素部分重叠；（b）少数项目在两个国家对非转介儿童的区分能力存在差异（即项目功能差异）；（c）在跨国评估具有相同精神病理严重程度的儿童的严重程度水平时存在差异。解决心理测量差异、限制冗余，并使儿童的精神病理严重程度水平与测量该严重程度的项目相匹配，可能会促进更准确、经济的评估。
