Obstructive sleep apnea knowledge-and-attitudes “OSAKA” questionnaire
The “Osaka questionnaire” for obstructive sleep apnea most commonly refers to the Obstructive Sleep Apnea Knowledge and Attitudes (OSAKA) questionnaire, which is a validated instrument used to measure clinicians’ knowledge about and attitudes toward OSA. [1]
The OSAKA questionnaire is not a patient screening test for diagnosing OSA. [1]
Questionnaire format
The OSAKA instrument contains two domains: knowledge items and attitude items. [1]
- Knowledge domain: 18 items scored as true/false statements. [1]
- Attitude domain: 5 items scored on a Likert scale. [1]
- Total length: commonly described as a 23-item instrument. [3]
Target population and intended use
The OSAKA questionnaire was developed to assess physicians’ knowledge and attitudes about adult OSA. [1]
The questionnaire is used in educational research and quality-improvement studies evaluating knowledge gaps and confidence regarding OSA recognition and management. [1]
Pediatric variant “OSAKA-KIDS”
A pediatric-adapted version exists for childhood obstructive sleep apnea, named OSAKA-KIDS. [2]
- OSAKA-KIDS length: 23-item, self-administered questionnaire. [2]
Domain content structure
The knowledge and attitude items are designed to probe multiple OSA-related areas, including epidemiology, pathophysiology, symptoms, diagnosis, and treatment. [3]
Scoring approach
The knowledge domain produces a knowledge score across the true/false items. [1]
The attitude domain uses Likert responses to generate an attitude/confidence score reflecting perceived importance and confidence in OSA management. [1]
