Résumé
The Epworth Sleepiness Scale for Children and Adolescents (ESS-CHAD) measures daytime sleepiness, but had not previously been validated in children <12 years of age. Data from a sodium oxybate (SXB) study in pediatric participants with narcolepsy with cataplexy (ClinicalTrials.gov, NCT02221869) were used in this validation study. SXB-naive participants completed an open-label titration period prior to entering a 2-week stable-dose period; participants taking SXB at study entry entered a 3-week stable-dose period. The analysis population (N = 100) had a mean (SD) age of 11.9 (2.39) years. Internal consistency as assessed by Cronbach's alpha was 0.750 (95% CI, 0.681-0.819). The intraclass correlation coefficient for the test-retest reliability assessment (n = 64 with stable or no stimulant use at study entry) was 0.755 (95% CI, 0.626-0.844). Responsiveness to change, measured as the mean within-person change in 1-week ESS-CHAD score over time in SXB-naive participants (n = 59) from baseline (before taking SXB) to end of the stable-dose period (taking the titrated amount of SXB), was -6.31 (95% CI: -7.61, -5.00; nominal P < 0.0001). For convergent construct validity, the mean (SD) scores for female (n = 40) and male (n = 60) participants were 13.98 (4.440) and 14.65 (4.050), respectively (nominal P = 0.4430). For divergent construct validity, the mean (SD) scores were 16.31 (2.978) in the group who were taking neither SXB nor stimulants at study entry (n = 32) and 13.47 (4.400) in the group taking SXB with or without stimulants at study entry (n = 68; nominal P = 0.0003). This evidence supports the validity of the 1-week ESS-CHAD in a pediatric population with narcolepsy.

OBJECTIVE/BACKGROUND
The Epworth Sleepiness Scale for Children and Adolescents (ESS-CHAD) measures daytime sleepiness, but had not previously been validated in children <12 years of age.
PATIENTS/METHODS
Data from a sodium oxybate (SXB) study in pediatric participants with narcolepsy with cataplexy (ClinicalTrials.gov, NCT02221869) were used in this validation study. SXB-naive participants completed an open-label titration period prior to entering a 2-week stable-dose period; participants taking SXB at study entry entered a 3-week stable-dose period.
RESULTS
The analysis population (N = 100) had a mean (SD) age of 11.9 (2.39) years. Internal consistency as assessed by Cronbach's alpha was 0.750 (95% CI, 0.681-0.819). The intraclass correlation coefficient for the test-retest reliability assessment (n = 64 with stable or no stimulant use at study entry) was 0.755 (95% CI, 0.626-0.844). Responsiveness to change, measured as the mean within-person change in 1-week ESS-CHAD score over time in SXB-naive participants (n = 59) from baseline (before taking SXB) to end of the stable-dose period (taking the titrated amount of SXB), was -6.31 (95% CI: -7.61, -5.00; nominal P < 0.0001). For convergent construct validity, the mean (SD) scores for female (n = 40) and male (n = 60) participants were 13.98 (4.440) and 14.65 (4.050), respectively (nominal P = 0.4430). For divergent construct validity, the mean (SD) scores were 16.31 (2.978) in the group who were taking neither SXB nor stimulants at study entry (n = 32) and 13.47 (4.400) in the group taking SXB with or without stimulants at study entry (n = 68; nominal P = 0.0003).
CONCLUSIONS
This evidence supports the validity of the 1-week ESS-CHAD in a pediatric population with narcolepsy.
