Child and Adolescent Sleep Checklist (CASC) is designed to identify sleep
habits and to make a screening of sleep problems among preschoolers, elementary
school children, and high school students.
CASC has three versions. Parental / caregiver version is for all age groups
(ages 3-18) to be filled out by the caregivers. Student version (for elementary
school; ages 6-12) is to be filled out by students themselves under the
instruction of the examiners; i.e. teachers, caregivers, or medical professionals).
Student version (for high school students; ages 12-18) is to be filled
out by the students without instruction. In order to enable both cross
sectional and longitudinal studies, all these versions use same set of
CASC is open for clinical use and for research use. PDF files of the questionnaire can be downloaded through the link at "Download
CASC" page. For industrial use or commercial use, please contact us.
To maintain consistency of the questionnaire and the scoring results among
the studies, please use the questionnaire without modification. Currently available language options are English (international version)
and Japanese. Translation to other languages is welcomed. In order to avoid
having multiple translations for a language, please let us know of the
new language version when you have created. We are pleased to upload the
new language version on the CASC website.
