Cleveland Adolescent Sleepiness Questionnaire (CASQ)

Name of questionnaire Cleveland Adolescent Sleepiness Questionnaire (CASQ)
Type of questionnaire-description,age Self-report questionnaire

Measures day time sleepiness in ages 11-17 years of age.  Can be used clinical (in patients with OSA) and nonclinical (healthy adolescents)

 
Number of items 16 questions
Number of domains & categories 2
Name of categories/domains Degree of sleepiness – 11 questions (sleep in school, sleep in evening, sleep in transport) 
Alertness in school – 5 questions
Scaling of items 1 to 5 (Likert-type responses)
1 - never
2 - rarely
3 – sometimes
4 – often
5 – almost every day

Items involving alertness or feeling “wide awake” were reverse coded before summing.
Scoring available: with permission or free No scale; Score ranges between 16-80.  Higher scores would indicate greater sleepiness.  Total scores on the CASQ were negatively correlated with objective measure of sleep duration.
Scoring test-retest reliability Not reported
Scoring internal consistency Yes (Cronbach's α = 0.89)
Validity Construct validity: results correlated well with 2 other well established sleep questionnaires - School Sleep Habits Survey and Pediatric Daytime Sleepiness Scale. Weakly associated with PSG findings
Language English
Available forms (short and/or long etc.) Long
Translations in other languages (if yes, then list the languages) Portuguese, Persian6

Availability of questionnaire: needs permission from developer, cost or freely available Freely available (appendix to the reference given below1).  Contact author prior to use.
Limitations Enrollment issues may have led to a non-representative range of normal sleep behavior. No objective measures of sleepiness utilized (e.g. MSLT).
Link to the questionnaire (if available) Appendix of the reference given below1
Other comments Very easy to administer, may be used in conjunction with objective testing of pediatric sleep disordered breathing and daytime sleepiness. 
CASQ scores were significantly correlated with age, sleep debt and sleep duration. 
Offers a visual aspect to answer choices.
Patient populations in who questionnaire has been validated Middle school and high school age children1, children with sleep disordered breathing1, children with asthma2
