Insights
New Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric Sleep Disturbance and Sleep-Related Impairment item banks offer reliable child and parent assessments for sleep health. These tools aid clinical research and practice in pediatric sleep medicine.
Area of Science:
- Pediatric Sleep Medicine
- Psychometrics
- Patient-Reported Outcomes
Background:
- Assessing pediatric sleep disturbances and their impact on daily functioning is crucial for effective clinical care and research.
- Existing measures may not fully capture the subjective experience of sleep issues in children.
- Development of robust, validated tools is needed to improve pediatric sleep health assessment.
Purpose of the Study:
- To develop and evaluate the measurement properties of child-report and parent-proxy versions of the Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric Sleep Disturbance and Sleep-Related Impairment item banks.
- To establish the reliability and validity of these new pediatric sleep health measures.
Main Methods:
- A national sample of 1104 children (aged 8-17) and 1477 parents (of children aged 5-17) were recruited from an internet panel.
- Psychometric properties were evaluated using item-response theory, including factor analysis and reliability testing.
- Validity was assessed through correlations with existing pediatric sleep health measures and comparisons between clinical and non-clinical groups.
Main Results:
- Factor analysis identified two dimensions: Sleep Disturbance and Sleep-Related Impairment.
- The final item banks comprised 15 items for Sleep Disturbance and 13 for Sleep-Related Impairment, demonstrating high reliability (>0.90).
- Validity was supported by expected correlations with existing measures and higher scores in children with sleep problems or chronic conditions.
Conclusions:
- The PROMIS Pediatric Sleep Disturbance and Sleep-Related Impairment item banks provide valuable subjective assessments of pediatric sleep difficulties and daytime impairment.
- These measures are suitable for use in clinical research and practice to evaluate pediatric sleep health.
- Future research should focus on evaluating the responsiveness of these measures to clinical change in various patient populations.
Study Objectives:
To develop and evaluate the measurement properties of child-report and parent-proxy versions of the Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric Sleep Disturbance and Sleep-Related Impairment item banks.
Methods:
A national sample of 1104 children (8-17 years old) and 1477 parents of children 5-17 years old was recruited from an internet panel to evaluate the psychometric properties of 43 sleep health items. A convenience sample of children and parents recruited from a pediatric sleep clinic was obtained to provide evidence of the measures' validity; polysomnography data were collected from a subgroup of these children.
Results:
Factor analyses suggested two dimensions: sleep disturbance and daytime sleep-related impairment. The final item banks included 15 items for Sleep Disturbance and 13 for Sleep-Related Impairment. Items were calibrated using the graded response model from item-response theory. Of the 28 items, 16 are included in the parallel PROMIS adult sleep health measures. Reliability of the measures exceeded 0.90. Validity was supported by correlations with existing measures of pediatric sleep health and higher sleep disturbance and sleep-related impairment scores for children with sleep problems and those with chronic and neurodevelopmental disorders. The sleep health measures were not correlated with results from polysomnography.
Conclusions:
The PROMIS Pediatric Sleep Disturbance and Sleep-Related Impairment item banks provide subjective assessments of child's difficulty falling and staying asleep as well as daytime sleepiness and its impact on functioning. They may prove useful in the future for clinical research and practice. Future research should evaluate their responsiveness to clinical change in diverse patient populations.
