The Inventory of Callous-Unemotional Traits (ICU) is a widely used measure of callous-unemotional (CU) traits that may aid in the assessment of the diagnostic specifier "with limited prosocial emotions," which has been added to diagnostic criteria for conduct disorder. Though there is substantial support for use of the ICU total score, the scale's factor structure has been highly debated. Inconsistencies in past factor analyses may be largely attributed to failure to control for method variance due to item wording (i.e., half of the items being worded in the callous direction and half worded in the prosocial direction). Thus, the present study used a multitrait-multimethod confirmatory factor analytic approach that models both trait and method variance to test the factor structure of the ICU self-report in a clinically relevant, high-risk sample of justice-involved male adolescents (N = 1,216). When comparing the fit of empirical and theoretical models, goodness of fit indices (χ² = 1105.877, df = 190, root-mean-square error of approximation = .063, comparative fit index = .916, Tucker-Lewis index = .878, standardized root-mean-square residual = .051) provided support for a hierarchical four-factor model (i.e., one overarching callous-unemotional factor, four latent trait factors) when accounting for method variance (i.e., covarying positively worded items). This factor structure is consistent with the way the ICU was constructed and with criteria for the limited prosocial emotions specifier. In addition, measurement invariance of this factor structure across age, race, and ethnicity was supported, and the predictive validity of the ICU was supported across these demographic groups in predicting self-reported antisocial behavior and rearrests over a 5-year period following an adolescent's first arrest.

《冷酷无情特质清单》(ICU) 自我报告版：涉及正义的男性青少年的因素结构、测量不变性和预测有效性。


冷酷无情感特征清单 (ICU) 是一种广泛使用的冷酷无情感 (CU) 特征测量方法，可能有助于评估“亲社会情感有限”的诊断说明符，该诊断说明符已添加到品行障碍的诊断标准中。尽管人们大力支持使用 ICU 总分，但该量表的因子结构一直备受争议。过去因素分析中的不一致可能很大程度上归因于未能控制由于项目措辞而导致的方法差异（即一半项目的措辞是冷酷的方向，一半的措辞是亲社会的方向）。因此，本研究使用多特征多方法验证性因素分析方法，对特征和方法方差进行建模，以测试 ICU 自我报告的因素结构，该样本是涉及正义的男性青少年的临床相关高风险样本（N = 1,216）。比较经验模型和理论模型的拟合度时，拟合优度指数（χ2 = 1105.877，df = 190，近似均方根误差 = .063，比较拟合指数 = .916，Tucker-Lewis 指数 = .878，标准化均方根残差= .051）在考虑方法方差（即共变积极措辞的项目）时为分层四因素模型（即一个总体冷酷无情因素，四个潜在特质因素）提供了支持。该因素结构与 ICU 的构建方式以及有限亲社会情绪说明符的标准一致。 此外，该因素结构在年龄、种族和民族之间的测量不变性得到了支持，并且 ICU 在预测青少年自我报告的反社会行为和重新逮捕后 5 年内的预测有效性在这些人口群体中得到了支持。第一次被捕。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
