Objective: The present study aimed to validate the German version of the Conners Early Childhood (EC)™ among German-speaking children. Method: A total of 720 parental and 599 childcare provider ratings of 2- to 6-year-old children were surveyed throughout Germany. Validity was assessed by calculating exploratory factor analyses (EFAs) and confirmatory factor analyses (CFAs), and a series of multivariate analyses of variance (MANOVAs) to analyze associations between Conners EC™ symptom ratings and sociodemographic variables. In addition, parent and childcare provider ratings of Conners EC™ scales were correlated with a number of other well-validated German measures assessing preschoolers’ behaviors. Results: Although the EFA yielded different factors than the original scales, CFA revealed acceptable to good model fits. Conclusion: Overall, we confirmed the factor structure of the Conners EC’s™ American original within the German validation. The use of the American factor structure is justified and can be recommended to facilitate international research on psychopathology in early childhood.

目的：本研究旨在验证德语版 Conners Early Childhood (EC)™ 的德语版本。方法：对全德国 2 至 6 岁儿童的 720 名父母和 599 名儿童保育提供者的评分进行了调查。通过计算探索性因素分析 (EFA) 和验证性因素分析 (CFA) 以及一系列多变量方差分析 (MANOVA) 来分析 Conners EC™ 症状评级与社会人口学变量之间的关联，从而评估有效性。此外，Conners EC™ 量表的父母和儿童保育提供者评级与许多其他经过充分验证的德国评估学龄前儿童行为的措施相关。结果：尽管 EFA 产生了与原始量表不同的因素，但 CFA 显示可以接受良好的模型拟合。结论：总的来说，我们在德国验证中确认了 Conners EC's™ 美国原件的因子结构。美国因素结构的使用是合理的，可以推荐用于促进幼儿心理病理学的国际研究。
