Insights
Parent reports of child sleep duration can be improved using simple adjustment factors. These factors help align parent estimates with objective sleep measurements for better research and clinical use.
Area of Science:
- Pediatric Sleep Medicine
- Objective Sleep Measurement
- Parental Reporting Accuracy
Background:
- Parental reports are commonly used to estimate child sleep duration.
- Discrepancies exist between parental reports and objective sleep measures like actigraphy.
- Accurate sleep duration data is crucial for child health research and clinical assessment.
Purpose of the Study:
- To develop and validate adjustment factors for parent-reported child sleep time.
- To improve the accuracy of parent reports to match objective sleep measurements.
- To enhance the utility of parental sleep reports in research and clinical settings.
Main Methods:
- A community sample of 217 children (ages 4-9) participated.
- Children wore actigraph wristwatches for 7 days to objectively measure sleep.
- Parents completed nightly reports of their child's sleep duration.
Main Results:
- Parental reports overestimated sleep duration by approximately 24 minutes per night compared to actigraphy.
- Child age, gender, and sleep quality showed minimal impact on the accuracy of parent reports.
- Developed adjustment factors significantly reduced the difference between reported and objectively measured sleep.
Conclusions:
- Simple adjustment factors can substantially improve the accuracy of parent-reported child sleep duration.
- These validated factors enhance the correspondence between subjective and objective sleep data.
- The findings support the use of adjusted parent reports for clinical and research applications in pediatric sleep.
Objective:
To develop and evaluate adjustment factors to convert parent-reported time in bed to an estimate of child sleep time consistent with objective measurement.
Methods:
A community sample of 217 children aged 4-9 years (mean age = 6.6 years) wore actigraph wristwatches to objectively measure sleep for 7 days while parents completed reports of child sleep each night. After examining the moderators of the discrepancy between parent reports and actigraphy, 3 adjustment factors were evaluated.
Results:
Parent report of child sleep overestimated nightly sleep duration by ∼24 min per night relative to actigraphy. Child age, gender, and sleep quality all had small or nonsignificant associations with correspondence between parent report and actigraph. Empirically derived adjustment factors significantly reduced the discrepancy between parent report and objective measurement.
Conclusions:
Simple adjustment factors can enhance the correspondence and utility of parent reports of child sleep duration for clinical and research purposes.
