Executive function (EF) is frequently an area of vulnerability in conditions associated with intellectual disability, like Down syndrome (DS). However, current EF evaluation approaches are not designed for children with underlying neurodevelopmental conditions and may not demonstrate construct validity due to interpretational confounds. The current study evaluated the construct validity of a novel battery designed to reduce measurement confounds in the assessment of EF in young children with DS. Participants were 124 children with DS (ages 2 to 8 years) who completed a set of adapted EF tasks. Exploratory graph analysis demonstrated that a two-factor solution (an Inhibition factor and a Working Memory/Flexibility factor) was the best fit for the data, providing evidence of construct validity for the adapted EF battery.
执行功能（EF）在与智力残疾相关的病症中，如唐氏综合征（DS），常常是一个易受影响的领域。然而，当前的执行功能评估方法并非为患有潜在神经发育病症的儿童设计，并且由于解释性混淆因素，可能无法证明其结构效度。本研究评估了一种新型测试组合的结构效度，该测试组合旨在减少对患有唐氏综合征的幼儿进行执行功能评估时的测量混淆因素。参与者为124名患有唐氏综合征的儿童（年龄在2至8岁之间），他们完成了一组经过改编的执行功能任务。探索性图表分析表明，双因素解决方案（抑制因素和工作记忆/灵活性因素）最适合该数据，为改编后的执行功能测试组合提供了结构效度的证据。
