Insights
Parental reports of young children's sleep duration are highly correlated with objective measurements. This suggests parent-reported sleep data can be valuable for surveys assessing relative sleep differences in populations.
Area of Science:
- Pediatrics
- Sleep Medicine
- Research Methodology
Background:
- Accurate sleep duration data is crucial for child development studies.
- Parental reporting is a common method for collecting sleep data, but its validity requires assessment.
Purpose of the Study:
- To evaluate the accuracy of parental reports on young children's sleep duration.
- To compare parent-reported sleep hours with objectively measured sleep hours.
Main Methods:
- 21 healthy children aged 3-4 years participated.
- Objective sleep monitoring was conducted over 3 consecutive nights using a small instrument.
- Parents reported their children's sleep hours during the same period.
- Statistical analyses included Pearson's correlation coefficients and paired t-tests.
Main Results:
- A high correlation (r=0.90, p<0.001) was found between reported and objectively measured sleep hours.
- Parents tended to overestimate children's sleep duration.
- The difference between reported and actual sleep hours was approximately 0.92 hours.
Conclusions:
- Parental reports of sleep duration show high validity when compared to objective measures.
- Despite a tendency for overestimation, parent-reported sleep data is suitable for surveys focusing on relative sleep differences within a population.
Abstract:
The aim of this study was to evaluate the validity of sleeping hours of young children as reported by their parents. The subjects were 21 healthy children aged 3 to 4 years. They were asked to attach a small instrument for calculating sleeping hours objectively, over 3 consecutive nights. Parents reported the sleeping hours of their children during the study periods. The mean values were used in the analysis. Pearson's correlation coefficients and paired t-tests were used to evaluate the correlations and differences between the reported and objectively measured sleeping hours. The correlation coefficient and difference between the reported and assumed (objective sleeping hours representing the difference between times for falling asleep and waking) sleeping hours were 0.90 (p<0.001) and 0.79 hours (95% confidence interval: 0.59-0.99), respectively. The correlation coefficient and difference between the reported and actual (the assumed sleeping hours minus the sum of epochs being scored as awake during the assumed sleep) sleeping hours were 0.90 (p<0.001) and 0.92 hours (0.73-1.10), respectively. Although parents tended to overestimate the sleeping hours of their children, the correlation between the reported and objective sleeping hours is high, which indicates that reported sleeping hours could be used in a survey that requires data on relative differences in sleeping hours amongst a given population.
