Effect of Nap on Daytime Functioning in Primary School Students
- Conditions
- Sleep Deprivation
- Registration Number
- NCT04270539
- Lead Sponsor
- The University of Hong Kong
- Brief Summary
Previous studies showed that insufficient sleep has a negative impact on children's physical and psychological health. Napping was found to decrease sleepiness and improve daytime functioning in adults and adolescents. The effects of napping on children, however, is unknown. The current study aims to test the effects of short daytime classroom naps on daytime functioning and behaviour in elementary school children.
- Detailed Description
This study is an interventional study testing the effects of short daytime nap on children's cognitive functioning and daytime behaviour. Primary school children will be randomised to either experimental (nap) or control group (no nap) by class. Measurements include parent-report questionnaires, children's self-report questionnaires, and cognitive tasks.

- Primary Outcome Measures
Name Time Method Change in objectively measured cognitive performance (working memory) Day 1 (before napping), Day 1 (after napping), two weeks and two months after intervention accuracy in match to sample task
Change in objectively measured cognitive performance (sustained attention) Day 1 (before napping), Day 1 (after napping), two weeks and two months after intervention Lapses defined by reaction time (RT) more than 500ms in psychomotor vigilance task
Change in objectively measured cognitive performance (inhibitory control) Day 1 (before napping), Day 1 (after napping), two weeks and two months after intervention reaction time (ms) in Go-no go task
- Secondary Outcome Measures
Name Time Method Change in daytime behaviour (emotional & behavioural problems) Day 1 (before napping), Day 1 (after napping), two weeks and two months after intervention Daytime behaviors as measured by Strengths and Difficulties Questionnaires (SDQ). Higher scores suggest more emotional and behavioural problems.
Change in daytime sleepiness Day 1 (before napping), Day 1 (after napping), two weeks and two months after intervention Daytime sleepiness as measured by Pediatric Daytime Sleepiness Scale (PDSS). Higher scores suggest more sleepiness.
Change in daytime behaviour (ADHD symptoms) Day 1 (before napping), Day 1 (after napping), two weeks and two months after intervention Strengths and Weakness of Attention-Deficit/ Hyperactivity-symptoms and Normal-behaviors (SWAN). Higher scores suggest more severe ADHD symptoms
