This study examined the role of callous-unemotional (CU) traits in preschoolers with externalizing behavior problems (EBP) and their response to time-out (TO). One hundred ninety preschoolers (76% boys, M = 4.92) with at-risk/clinically elevated levels of EBP participated in an 8-week summer treatment program (STP-PreK). Total number of minutes spent daily in TO for intentional aggression (IA) and repeated non-compliance (RNC) were recorded during the initial (T1) and final (T2) phases of the STP-PreK. After accounting for severity of EBP and levels of TO at T1, higher levels of CU traits predicted greater total levels of TO at T2. An interaction also emerged between symptoms of oppositional defiant disorder (ODD) and CU traits in predicting IA. Specifically, greater ODD symptoms predicted fewer number of IA related TO at T2, but only for children with low CU traits. Implications for treatment are discussed.
本研究考察了冷酷无情（CU）特质在有外化行为问题（EBP）的学龄前儿童中的作用及其对暂停（TO）的反应。190名有风险/临床EBP水平升高的学龄前儿童（76%为男孩，M = 4.92）参加了一个为期8周的暑期治疗项目（STP-PreK）。在STP-PreK的初始阶段（T1）和最后阶段（T2），记录了每天因故意攻击（IA）和反复不服从（RNC）而花费在TO上的总分钟数。在考虑了T1时EBP的严重程度和TO水平后，较高水平的CU特质预测了T2时TO的更高总水平。在预测IA方面，对立违抗障碍（ODD）症状和CU特质之间也出现了交互作用。具体而言，更多的ODD症状预测了T2时与IA相关的TO次数较少，但仅适用于CU特质较低的儿童。文中讨论了对治疗的启示。
