WESTCHESTER, Ill. A study published in the October 15 issue of the Journal of Clinical Sleep Medicine (JCSM) features the Cleveland Adolescent Sleepiness Questionnaire (CASQ), a new self-completed instrument to measure excessive daytime sleepiness in adolescents.

The study, led by James C. Spilsbury, PhD, of the Division of Clinical Epidemiology and Biostatistics in Cleveland, Ohio, focused on a subsample of 411 adolescents between 11-17 years of age, who were recruited from area schools and churches, as well as a second subsample of 62 adolescents with a diagnosed sleep related breathing disorder, all of whom completed the CASQ along with two other surveys measuring daytime sleepiness and other sleep parameters (sleep duration on school nights, sleep duration on non-school nights, and sleep debt). The third source of adolescents for the sample consisted of participants in a community-based cohort study (Cleveland Sleep and Health Study) who did not have evidence of a sleep related breathing disorder by objective overnight polysomnographic monitoring or reported snoring.

According to the study, the CASQs internal consistency was good. Correlations between the CASQ and the two other surveys measuring daytime sleepiness and sleep parameters gave preliminary evidence of the CASQs construct validity based on the following findings:

Greater CASQ scores, reflecting increased daytime sleepiness, were significantly associated with decreased sleep duration in both normative and sleep disorder samples, as well as with increased sleep debt in the normative sample.

CASQ scores were positively correlated with age.

The CASQ displayed convergent validity by its strong positive correlations with the two other surveys measuring daytime sleepiness and other sleep parameters.

Adolescents with a sleep related breathing disorder had higher CASQ scores than adolescents without a sle
