There is a need to know whether callous-unemotional (CU) traits identify a more severe group of oppositional defiant children (ODD). The aim of this study is to ascertain cross-sectionally and longitudinally the specific contribution of CU levels and the presence of ODD in the psychological state of preschool children from the general population. A total of 622 children were assessed longitudinally at ages 3 and 5 with a semi-structured diagnostic interview and questionnaires filled out by parents and teachers. In multivariate models simultaneously including ODD diagnosis and CU levels, controlling by socioeconomic status, ethnicity, sex, severity of conduct disorder symptoms and other comorbidity, high CU scores were related to higher levels of aggression, withdrawn, externalizing and global symptomatology, functional impairment and higher probability of comorbid disorders and use of services. The contribution of CU traits on children's psychological state was not moderated by the presence/absence of ODD. Stability for CU traits and number of ODD-symptoms between ages 3 and 5 was statistically significant but moderate-low (intra-class correlation under .40). Assessment and identification of CU traits from preschool might help to identify a subset of children who could have socialization problems, not only among those with ODD but also among those without a diagnosis of conduct problems.
有必要了解冷酷无情（CU）特质是否能识别出更严重的对立违抗障碍儿童（ODD）群体。本研究的目的是从横断面和纵向角度确定CU水平以及ODD的存在对普通人群中学龄前儿童心理状态的具体影响。共有622名儿童在3岁和5岁时接受了纵向评估，采用了半结构化诊断访谈以及由家长和教师填写的问卷。在同时纳入ODD诊断和CU水平的多变量模型中，控制社会经济地位、种族、性别、品行障碍症状的严重程度和其他共病情况后，高CU分数与更高水平的攻击行为、退缩、外化和总体症状、功能损害以及共病障碍和使用服务的更高可能性相关。CU特质对儿童心理状态的影响并不因ODD的存在与否而有所不同。3岁至5岁之间CU特质和ODD症状数量的稳定性具有统计学意义，但为中低水平（组内相关系数低于0.40）。从学龄前阶段评估和识别CU特质可能有助于识别出一部分可能存在社交问题的儿童，不仅包括患有ODD的儿童，也包括那些未被诊断为品行问题的儿童。
