Literature on the Inventory of Callous-Unemotional (ICU) traits has suggested different versions of the instrument for assessing these traits during development. However, consensus on the instrument version and the best factorial solution remains a matter of debate, with only a few studies having validated ICU versions from a longitudinal perspective. The current study aims to contribute to the literature by comparing ICU models in a longitudinal sample of early adolescents (N = 739; 70.6% of eligible subjects, 371 females and 368 males, in the 6th grade at baseline assessment and in the 8th grade at the second assessment). We tested the validity of various versions of the ICU scales and their respective dimensions by conducting a series of confirmatory factor analyses to verify the factor structure, alongside assessments of internal consistency. For the best-fitting structure, we then analyzed gender and longitudinal invariance in addition to construct and predictive validity, using internalizing and externalizing criteria as well as prosocial behavior. From the comparative analysis, it emerged that the abbreviated 11-item ICU scale version displayed overall better data fit than the full 24-item version. Moreover, its confirmed gender invariance underscores its applicability across genders within the studied age group. With regard to longitudinal invariance, our findings advise caution when comparing ICU scores across early adolescence. Practical implications are discussed.
关于无情无感（ICU）特质量表的文献表明，在该量表的编制过程中有不同版本用于评估这些特质。然而，对于量表版本和最佳因子分析解决方案仍存在争议，仅有少数研究从纵向角度验证过ICU量表的版本。本研究旨在通过比较处于青少年早期的纵向样本（N = 739；占符合条件受试者的70.6%，371名女性和368名男性，基线评估时为六年级，第二次评估时为八年级）中的ICU模型，为相关文献做出贡献。我们通过进行一系列验证性因子分析来检验ICU量表不同版本及其各自维度的有效性，以验证因子结构，并同时评估内部一致性。对于拟合度最佳的结构，我们随后除了构建效度和预测效度外，还使用内化和外化标准以及亲社会行为分析了性别和纵向不变性。从比较分析中可以看出，缩写的11项ICU量表版本总体上比完整的24项版本显示出更好的数据拟合度。此外，其已证实的性别不变性突出了它在研究年龄组内不同性别中的适用性。关于纵向不变性，我们的研究结果建议在比较青少年早期的ICU分数时要谨慎。文中还讨论了实际意义。
