Abstract Background Sleep problems have an impact on executive functioning in the general population. While children with Down syndrome (DS) are at high risk for sleep problems, the impact of these sleep problems on executive functioning in school‐age children with DS is less well documented. Our study examined the relationship between parent‐reported and actigraphy‐measured sleep duration and sleep quality with parent and teacher reports and neuropsychology assessments of executive functioning among school‐age children with DS. Method Thirty school‐age children with DS wore an actigraph watch for a week at home at night. Their parent completed ratings of the child's sleep during that same week. Children completed a neuropsychology assessment of their inhibitory control, ability to shift and working memory. Their parents and teachers completed rating scales to assess these same constructs of executive functioning. Results Parent reports of restless sleep behaviours on the Children's Sleep Habits Questionnaire (CSHQ), but not actigraph‐measured sleep period or efficiency, were predictive of parent reports of concerns with inhibitory control, shifting and working memory, and of teacher reports of inhibitory control. No measure of sleep was predictive of executive functioning as measured by the neuropsychology assessment. Conclusion The study findings corroborate the preliminary literature that parent‐reported sleep problems are related to executive functioning in school‐age children with DS, particularly in the area of inhibitory control across home and school. These findings have implications for understanding contributing factors to academic performance and school behaviour in school‐age children with DS.
