Abstract

The factorial structure of the Inventory of Callous Unemotional Traits (ICU) is currently under dispute. The present study aims to test the factorial structure of a Greek adaptation of the ICU by considering item keying variance and examining alternative theoretical and empirically derived models. Additionally, it aims to investigate the nomological network of the ICU subscales, after controlling for item keying variance. The sample consisted of 1536 Greek-Cypriot adolescents, who completed a battery of questionnaires, including the ICU. Results showed that the consideration of item keying variance improved the overall fit of all the examined models and led to significant changes in the predictive validity of the subscales, while method factors presented distinct patterns of associations with external variables. Overall, results suggest that ICU is contaminated by item keying variance, which can be filtered out to provide clinically useful insight into the factorial structure of the ICU.

摘要

当前对残酷的非情绪性状量表（ICU）的析因结构存在争议。本研究旨在通过考虑项键控方差并检查替代的理论和经验推导模型来测试希腊文ICU改编的阶乘结构。此外，它的目的是在控制项目关键差异后，调查ICU分量表的法理网络。样本包括1536名希族塞人青少年，他们完成了包括ICU在内的一系列调查问卷。结果表明，项目项差异的考虑改善了所有检验模型的总体拟合度，并导致子量表的预测有效性发生了显着变化，而方法因素则呈现出与外部变量相关的独特模式。全面的，
