This study evaluated whether sluggish cognitive tempo (SCT) is separable from ADHD-inattention (IN) and uniquely associated with internalizing dimensions in preschool children in South Korea.
Mothers of 172 preschool children (ages 4-6 years; 52% girls) rated children's SCT, ADHD-IN, ADHD-hyperactivity/impulsivity (HI), oppositional defiant disorder (ODD), aggression, emotional reactivity, anxiety/depression, somatic complaints, withdrawal, and sleep problems.
Eight of 10 SCT symptoms showed convergent and discriminant validity with ADHD-IN. ADHD-IN remained significantly positively associated with ADHD-HI, ODD, and aggressive behavior after controlling for SCT, whereas SCT was no longer positively associated with these externalizing behaviors after controlling for ADHD-IN. Both SCT and ADHD-IN were uniquely associated with greater emotionally reactivity, anxiety/depression, and withdrawal. Only SCT was uniquely associated with somatic complaints, and only ADHD-IN was uniquely associated with sleep problems.
Findings replicate results with children and adolescents, thus expanding evidence for the validity of SCT in early development.
本研究评估了迟缓认知节奏(SCT)是否可与注意力缺陷多动障碍的注意力不集中型(ADHD-IN)相区分,以及是否与韩国学龄前儿童的内化维度存在独特关联。
172名学龄前儿童(4至6岁;52%为女孩)的母亲对孩子的SCT、ADHD-IN、ADHD多动/冲动型(HI)、对立违抗障碍(ODD)、攻击行为、情绪反应性、焦虑/抑郁、躯体不适、退缩行为和睡眠问题进行了评分。
10项SCT症状中的8项与ADHD-IN具有聚合效度和区分效度。在控制SCT后,ADHD-IN仍与ADHD-HI、ODD和攻击行为显著正相关,而在控制ADHD-IN后,SCT与这些外化行为不再呈正相关。SCT和ADHD-IN均与更高的情绪反应性、焦虑/抑郁和退缩行为存在独特关联。只有SCT与躯体不适存在独特关联,只有ADHD-IN与睡眠问题存在独特关联。
研究结果重复了在儿童和青少年中的研究结果,从而扩展了SCT在早期发育中有效性的证据。
