The Children's Sleep Habits Questionnaire (CSHQ) is often used to assess sleep in children with autism spectrum disorder (ASD), but little is known about its factor structure in younger children with ASD. We evaluated alternative factor structures and measurement invariance for CSHQ items in 2- to 4-year-olds with ASD or typical development (TD). Bifactor models indicated subscales' variance was subsumed by a general factor predominantly reflecting sleep initiation and nighttime awakening items. A factor consisting of 7 of these items was measurement invariant across ASD and TD. Thus, comparisons between young children with ASD and TD is appropriate for a measure composed of 7 CSHQ items relating to sleep initiation and awakenings but not for other CSHQ item composites.
《儿童睡眠习惯问卷》(CSHQ)常用于评估自闭症谱系障碍(ASD)儿童的睡眠情况,但对于 2 至 4 岁 ASD 儿童的该问卷因子结构知之甚少。我们评估了 ASD 和典型发育(TD)儿童的 CSHQ 项目的替代因子结构和测量不变性。双因素模型表明,子量表的方差被一个主要反映睡眠起始和夜间觉醒项目的一般因素所包含。由其中 7 项组成的一个因子在 ASD 和 TD 之间具有测量不变性。因此,对于由 7 项与睡眠起始和觉醒有关的 CSHQ 项目组成的测量工具,比较 ASD 和 TD 年龄段的儿童是合适的,但对于其他 CSHQ 项目组合则不适用。
